    摘要: An improved method for manufacture of multifilamentary superconductors of the A.sub.3 B type having the A-15 crystal structure, such as Nb.sub.3 Sn, is disclosed in which rods or wires of the A material are disposed throughout a matrix consisting of Cu and the B material in substantially elemental form. The matrix is formed by compaction of powders of Cu; powders of the B may be mixed therewith or the B material may be infiltrated into pores between the individual Cu particles after compaction. The resultant composite has A, B and Cu distributed uniformly throughout its volume and can be worked to any desired final shape and size for heat treatment to form the A.sub.3 B material without intermediate annealing steps.

    摘要: The rate of calcining carbonaceous material in a rotary kiln is increased by introducing oxygen into the inlet of air fans mounted on the kiln. The introduction of oxygen is effected during a predetermined portion of each kiln revolution and is effective to enrich the oxygen content of air supplied to the kiln to approximately 23-25% oxygen. By so enriching the interior kiln atmosphere during calcining of material such as petroleum coke, greater temperatures are obtained than will be obtained by the use of air alone thereby accelerating the evolution and combustion of volatile materials during calcination. The accelerated evolution and combustion of such volatiles enables the rate at which carbonaceous materials can be calcined in a kiln of a predetermined length to be increased.

    摘要: A device for use in vacuum suction systems for withdrawing fluids from a patient's body cavity, such as the stomach, wherein the device includes a chamber that is located in the flow stream of such fluids between the patient and the source of vacuum. At predetermined intervals, the device forces a quantity of the withdrawn fluid from the chamber, back into the suction tubing leading to the patient such that some of the fluid previously removed from the body cavity is forced backward toward such cavity under a positive pressure to dislodge any obstructions that may have occurred in the tubing or at the end of such tubing. In the preferred embodiment, the device is effectively self-contained and needs no source of positive pressure or electricity for its operation and is readily and fully operable from present commercial intermittent suction systems without revamping or otherwise modifying existing systems.

    摘要: A vaporizer interlock system is disclosed which is used in an anesthesia machine having two calibrated vaporizers for providing an anesthetic to a patient and further having a selector valve with three positions, two extreme positions where one of the two vaporizers is being utilized and a middle position where neither vaporizer is used. The system prevents opening of either vaporizer when the selector valve is in the middle position. Also, when the selector valve is moved to one of its extreme positions selecting one of the vaporizers, the other vaporizer is prevented from being moved from its "off" position. The "on" vaporizer must thereafter be placed in its "off" position before the selector valve can be returned to its middle position. In addition, a quick disconnect means is shown for quickly attaching and detaching the vaporizers from the anesthesia machine.

    摘要: An anesthesia machine is disclosed wherein flowmeters used to denote flow of O.sub.2 and other gases are in the form of precalibrated modules. The modules each contain a flowtube, float and scale and are precalibrated and the modules sealed to prevent tampering or affecting the calibration. The flowmeter modules are thus readily inserted into or removed from the anesthesia machine by a single plug-in maneuver to a common manifold without further calibration or leak testing. A key index system prevents the mislocation of any particular flowmeter module in a machine.The flowmeter module has a lower manifold at its bottom where all plug-in connections are located. A flowtube containing the float extends upwardly from the manifold and has an easily visible scale for accurate readings. Internal tubing within the flowmeter module returns gas from the flowtube back to the outlet connection in the lower manifold. The flowmeter modules may be, therefore, completely tested for leaks, calibrated at the source and tamperproof measures included to prevent disassembly or in any way upsetting the calibration short of factory rebuilding the flowmeter module. Because the units are factory sealed, replacement of flowmeter modules may be made by personnel in the field unskilled with such machines.

    摘要: Ferrous parts are bonded together in a copper brazing furnace under suitable temperatures and a furnace atmosphere which, in the absence of parts, is comprised of at least 90% nitrogen, up to 7% combined hydrogen and carbon monoxide with hydrogen being greater than 50% of the total of CO and H.sub.2 and having a dew point between approximately -40.degree. to +10.degree. C. In the preheat section of a continuous belt furnace or the like, the dew point may range between -20.degree. to +10.degree. C. while in the furnace hot zone, the dew point is maintained between approximately -40.degree. to -10.degree. C. A brazing paste which is preferably a combined copper and 25-75% copper oxide paste is utilized. With such furnace atmosphere and paste composition, clean part surfaces, which permit superior wetting by molten copper and thus acceptable copper flow and penetration into the joint being bonded, are obtainable. The furnace atmospheres utilized enable increased life to be obtained from furnace materials such as brick insulation, muffles, conveyor belts, and heating elements.

    摘要: A liquid-vapor converter of a compact skid-mounted design is provided that efficiently converts a cryogenic liquid into a vapor, and which includes, in the same skid mounting, all necessary components necessary to receive the liquid and to provide therefrom a high pressure source of gas, particularly for use in recovery of product from oil wells. The design includes an internal combustion engine as a motive force to drive the main pump for pressurizing the vapor for its intended use. A heat exchanger receives the liquid and circulates the same through tubing, where the liquid is vaporized in the heat exchanger by ambient air being passed across the tubing to warm the liquid, thus effecting such vaporization. The heat exchanger utilizes heat from the engine exhaust to preheat the incoming ambient air prior to its passing in heat transfer relationship across the tubing. In addition, further heat may be provided to the incoming ambient air by positioning the engine radiator and/or the hydraulic oil cooler in the ambient air stream inlet. The overall converter is particularly adapted for use in oil well drilling locations where extreme care must be taken to avoid open flame or fires, such as off-shore drilling rigs.
