Abstract: A blade is provided for the cycloidal marine propellers or cycloidal aerial rotors. Said blade is provided with the capabilities, in response to the control system commands to dynamically and in real time; vary its relative pivot point position, change its planform by extending or retracting a trailing edge extension, differentially if needed on the right and left, turn the flap along the trailing edge in either direction or allow it to be turned by the flows. Said blade is also optionally provided with one or more elastic trailing edges whose stiffness is dynamically, and possibly differentially along the blade span, variable by the control system. For the reversal of the leading and trailing edges for operation in reverse airflow and other conditions the blades are provided with edges that can be made rigid when functioning as the leading edge and flexible if needed when functioning as the trailing edge. Also the blades are provided with the capability of varying their cross-sectional profile thickness and reshaping it. Finally the blades are given on command flow permeability along much of their surface. These capabilities will enable each control system controlled blade to continually optimally adjust to and make the best use of its immediate operating environment as it travels along its trajectory within each revolution.

Abstract: The bolts of this invention have been provided with the various means for preventing torque transmission to the bolt head when the nut is being tightened, thereby eliminating the need to hold it by a wrench while the nut is being tightened. A nut with a helical or similar cut is provided in order to assure more even distribution of stress among its thread coils. A few different flexible bolts are provided for assembling misaligned flanges and other misaligned connections. Lastly fasteners comprising very strong and light synthetic fiber string with a simple hoist-like assembly on one end and a round stopper-head on the other have been provided, not using the thread at all, to replace the heaviest, longest and most expensive bolts and nuts used on large pipes and pressure vessels or in applications where weight reduction is important.

Abstract: A system and a method for tracking items stored in a refrigerator which includes the identifying unit comprising a few known devices such as bar code reader or voice command processor for identifying the incoming and outgoing items also including an olfactory sensor. Said sensor in addition to identification is to be used also for assessing the items' degree of freshness for the purpose of determination of its actual expected maximum storage time—this determination will be made by the computer processor accessing the pertinent database(s) while using the digital smell signature for said access, when necessary. Said database will contain the storage data for opened or unpacked or cooked items for which the storage time data on the package is not applicable as well as possibly the items ingredients and the nutritional content. The items actual shelf storage location will be determined by means of the miniature motion detectors in combination with the optical scanners located in each shelf compartment or by means of making the shelves and the horizontal surfaces of compartments electrostatically charged and detecting the capacitative change. On the way in or out the item will be identified and the content of the appropriate section on display will be updated.

Abstract: A lock-washer of conical, annular or other shapes capable of elastic flattening when the threaded connection, of which it is a part, is tightened and having tabs along the perimeter of the central hole. For most embodiments the tabs' tips form a circle of a diameter slightly larger than that of a threaded part which is to pass through the central hole. When during tightening the axial force acting on the lock-washer reaches a pre-determined level and the lock-washer flattens, its central hole diameter decreases and the tab tips enter the thread channel, which will cause the thread to jam, thus preventing further tightening, thereby limiting the axial load in the threaded connection to a pre-determined level. Another embodiment provides a lock-washer which compresses and expands radially during tightening providing a visual and/or audible signal for the worker when said expansion and a corresponding axial load reach the designated level.

Abstract: A cycloidal rotor system having airfoil blades travelling along a generally non-circular, elongated and, in most embodiments, dynamically variable orbit. Such non-circular orbit provides a greater period in each revolution and an optimized relative wind along the trajectory for each blade to efficiently maximize lift when orbits are elongated horizontally, or thrust/propulsion when orbits are vertically elongated. Most embodiments, in addition to having the computer system controlled actuators to dynamically vary the blade trajectory and the angle of attack, can also have the computer system controlled actuators for dynamically varying the spatial orientation of the blades; enabling their slanting motion upward/downward and/or backsweep/forwardsweep positioning to produce and precisely control a variety of aerodynamic effects suited for providing optimum performance for various operating regimes, counter wind gusts and enable the craft to move sideways. Thus a rotor is provided, which when used in a VTOL rotorcraft, will require lower engine power to match or exceed the operating performance of VTOL rotorcrafts equipped with prior art cycloidal rotors, this rotor also offers increased efficiency and decreased required power when used for generating the propulsive force for various vehicles or used as a fan.

Abstract: A replacement for cylindrical dowel nuts is provided and is a hollow cylindrical nut with a threaded hole on top and an unthreaded hole at the bottom which is for the threaded shank to enter. This hollow dowel nut elastically compresses during tightening to act like a lock-washer to prevent loosening. Several solutions are provided to make the top of the nut thicker to fit more thread coils than what wall thickness would otherwise permit. To improve loosening prevention further and also provide overtightening prevention a hollow nut with flatter bottom and a narrow gap bisecting the lower hole are used which during tightening cause right and left edges of said gap to be pushed towards the bolt strongly gripping it which prevents overtightening and loosening. “C” shaped nuts also provided which cause misalignment and jamming in the thread when compressed thereby also preventing loosening and overtightening.

Abstract: Springs of different types are provided with the ability to dynamically change stiffness. For one embodiment turning the elastic beams with elongated cross-section inside a leaf spring's housing plate, leaf springs stiffness is varied. Friction forces between plates are also controlled by using a thin layer of electro-rheological fluid between plates whose viscosity is greatly varied by application of voltage. Second embodiment springs made of hollow tubing filled with oil wherein inside pressure is changed by an actuated membrane or piston whose movement drastically increases the hydrostatic pressure inside the tubing and thus increases tensile stress in the tubing's wall and expands the diameter of tubing which may be of cross-section purposely suited for expansion, thereby increasing its stiffness or decreasing it with any desired frequency or changing the stiffness possibly in milliseconds for a period of time. These springs that are also provided with limited actuation capability are especially suitable for counteracting vibration when changing stiffness with same frequency as vibration. When a number of such springs are used to support one load, they can be used for dynamically varying the load distribution or preventing a change to said load distribution in real time. Another embodiment features annular corrugated tubing which with the increase in inside pressure will substantially lengthen, producing large coil radius expansion and accordingly large decrease in spring stiffness, still another embodiment uses corrugated tubing inside a retaining cylinder; said tubing expands lengthwise when inside pressure is increasing but retaining cylinder forces the lengthening tubing to produce new coils inside of it resulting in spring length increase that is actuation and large stiffness variability resulting from coil number variability.
