摘要:
Nuclear devices are detonated periodically inside an underground cavity in which a working fluid absorbs most of the thermal energy released by the device detonation. The kinetic energy contained in the shock wave created within the working fluid is absorbed by shock absorbers located outside the inner wall of the cavity. This wall consists of adjacent plate segments that separate and recoil outwardly as do pieces of shells of fragmentation grenades. The shock wave kinetic energy is transferred to the segments that are constrained in their outwardly-directed flight by shock absorbers. The shock-absorbing system is solidly attached to the rock structure surrounding the cavity. The loading transmitted to the rock is of a much lower intensity than that which the plate segments sense, though of a much longer duration. The momentum trapped in the shock wave is thus absorbed by the rocks but in a manner such that the rock structure is not affected. The survival of that rock structure insures that the cavity could be used a very large number of times, sequentially spaced. The cavity is sealed positively from the outside at all times by specially-designed bellows that surround individual shock absorber elements.

An external combustion engine including a rotary motor equipped with non-sliding vanes but conformable to the shapes of the envelopes within which they are contained and forced to operate and a combustion member comprising a sleeve in which a piston is free to reciprocate. The two end closures of the sleeve and the piston ends cooperate to form combustion chambers at both ends of the piston strokes. The motor compresses air for admission in the combustion chambers where fuel is burned and is also used for expanding the combusted gas resulting from the fuel combustion. The gas expansion produces more energy than is required to compress the air. The energy difference constitutes the energy yielded by the engine in the form of shaft power. The air admission the combusted gas exhaust from the combustion member, the fuel injection and ignition are all timely controlled by the piston motion. The air compression and the gas expansion may be performed by a different set of vanes, but may also be performed by the same set of blades, depending upon the manner in which the motor is constructed. In one motor configuration, rigid blades are articulated to allow the blade conforming, whereas blades are flexibly constructed in another alternate motor configuration, to the same end.

摘要:
A slidable vane motor is used in conjunction with an externally located combustion member in which fuel is burned and compresses air for delivery to the combustion member and expands the combusted gas resulting from the fuel combustion in the compressed air. The vane motor and combustion member thus cooperate to form an external combustion engine. The energy extracted from the expansion of the gas is greater than the energy required to compress the air. The energy difference is delivered by a drive shaft external to the engine. The motor vanes slide quasi radially in guiding slots as the motor rotates to cause volumes of air trapped between contiguous vanes to decrease and trapped volumes of gas to increase concurrently. The vanes are thus subjected to pressure differentials which are applied quasi normally onto the vane sliding surfaces. The resulting torque is reacted by the action of high pressure air cushions located between the cooperating surfaces of the vanes and their slots. Physical contacts between the vanes and the slots is thus prevented. A similar use of air cushions is made to eliminate friction between the vane edges, other moving parts of the motor and those parts of the motor which are fixed.

Structures are constructed and arranged on a camp site to provide shelter to evacuees seeking survival, as a GROUP, in case of a nuclear attack on or near their city. The construction, disposition, arrangement and shapes of the structures are such that people inside these structures are not affected by the blast of the nuclear explosion, for peak overpressure levels well above those which conventional structures cannot survive. The structures and the camp site are equipped to provide the elimination of fallout dust in a short time so as to bring the total exposure of the evacuees to radioactivity levels low enough to be safe, until the radioactivity within miles has decayed down to levels acceptable for long time exposure. The sheltering structures are interlinked to provide a quasi normal indoor way of life during the period of necessary confinement of the evacuees, so that no evacuee feels the urge to leave the protection provided within the compound against the surrounding grounds radioactivity. The compound configuration is set up to provide the maximum effectiveness for defense against any marauding gangs, until protection can be secured from the police authorities in charge. The size and the implementation for autonomous survival of the camp site are such that no support from the outside world is required for a period of up to several weeks. The overall camp site set up is also such that peacetime and economical use of the camp facilities and amenities can be made, when it is not utilized as survival camp, which, of course, is the most fervent hope of everyone.

A double-bar riding wheel positioned between two circular cross-section bars acting as support. One end of each bar is partly restrained but permits a limited amount of rotational movement of the bar. The other end of each bar is held by an operator's hand by means of a handle, thus providing the wheel actuating motion by lifting the handles. The bar cross-sections generally increase from one end to the other. The riding wheel is equipped with two shafts, one attached to each one of the two sides of the wheel. The combination of the variations of the bar shapes lengthwise and of the shaft shapes lengthwise makes it difficult for the wheel to remain astride of the two bars while being urged to ride forward by the operator. The shapes of both shafts and bars are such that the degree of difficulty increases from one end of the bars to the other. The object of the operation, is to make the wheel ride the full length of the bars, or at least to proceed as far as possible from the starting point. The movements of the handles are automatically limited so that only one shaft may fall off its rolling position on top of a bar, thus stopping the wheel riding. The wheel is prevented from ever falling between the two bars. Indicia on the bars are used to record the location where the wheel then stops. Various coordinated motions of both hands are needed to control and steer a successful wheel ride, which requires manual skill and dexterity from the operator.

Apparatus and method for packaging, guarding and sealing a portion of a publication. The pages of the publication contained in the portion thus packaged, guarded and sealed are prevented from being viewed until and unless a seal is broken, at which time these pages and/or content can then be freely viewed. The cover, pages and content of the other portions of the publication which are not so protected, packaged, guarded and sealed are permitted to be viewed as though the protecting apparatus guarding the sealed off portion of the publication were not present. The apparatus and the method can be used with publications of varied sizes and for guarding portions of the publication which may contain various amounts of pages, as required and as deemed appropriate at the time the publication whole content is assembled for binding. Once the seal has been broken, it is made impossible to replace it without leaving evidence and/or proof that the protector has been tampered with and that the content of the sealed portion has therefore been viewed.

A method and an apparatus for processing ripe avocados in which the pulp is separated from the outer skin and from the seed in sequenced operations. The pulp can then be reduced to a paste-like product and frozen for easy preservation, handling and marketing. The avocado pulp does not acquire its consistency and reach its oil content until the fruit has ripened to a stage where the pulp is soft. At this stage, a few days are available to process the avocado before it spoils. The ripening process occurs naturally after the fruit has been picked off the tree, providing it is left undisturbed with the seed and the skin untouched. Otherwise, no ripening takes place. Because the external surface of a ripe avocado is so soft and because its seed is so hard, the extraction of the edible and tasty pulp is difficult to perform with automatically operating machinery. Such machinery and the attendant method are the subject of the present disclosure. The ripe avocado is firmly held by means of its seed while the skin and the pulp are removed automatically.
摘要:
A bar-riding wheel positioned on a single circular cross-sectional bar. One end of the bar is partly restrained but allows for a limited amount of swinging and/or rotating motions. The other end of the bar is held by the operator's hand, by means of a handle, and provides its actuating motion to the wheel by lifting the handle. The bar cross-section generally increases from its free end to its partly restrained end. The riding wheel exhibits a deeply shaped groove such that as the wheel rolls in the direction of the increasing cross section of the bar, the center of gravity of the wheel eventually rises, up to and beyond a point where the wheel riding position becomes unstable. A mobile counterweight system causes the instantaneous center of gravity of the riding wheel to be located below its instantaneous axis of rotation at all times. The object of the operation is to successfully manipulate the bar such that the riding wheel rolls as far as possible, in the unstable region without toppling over. The farther the wheel rolls along the unstable region, the greater the skill of the operator. Indicia on the bar provides an accurate measurement of the operator's skill.

A specially shaped vessel containing a mixture of solid matter and liquid in which fresh liquid and fresh solid matter are introduced at one end and the processed liquid and solid matter are extracted at the other end. When such a vessel stands, both ends act as the two sides of a communicating vessel arrangement. The liquid levels are always the same on both sides of said vessel. Liquid is poured out from only one end through a spout equipped with a strainer to prevent the solid matter from leaving the vessel. Both ends are covered by a separate lid. To add fresh liquid and solid matter and to extract steeped solid matter, the lid covering the proper end is taken off, while the vessel is standing. To pour liquid fully processed, the lids are left in place, but the outlet lid needs only be turned slightly. As needed, both fresh liquid and solid matter to be steeped are introduced through the inlet end. As liquid and solid matter are extracted and as fresh liquid and fresh solid matter are added, always in the same direction, the mixture of liquid and solid matter, said solid matter thus macerating in said liquid, slowly works its way from the filling end to the extracting end of the vessel. As the vessel contents rest, between periods of either filling or extraction, the liquid remains still and undisturbed, thus being given the opportunity to decant. Depending upon the degree of maceration desired, the natures of the liquid and of the solid matter, the size of the vessel and the rate at which steeping takes place, the ideal rate of extraction is established. If and when used for only one type of liquid and of solid matter, the macerator-decanter can operate without interruption continuously for ever. The quality and characteristics of the extracted products, both liquid and solid matter, are thus automatically caused to remain consistently the same and at their optimum ideal conditions, once established.
