Abstract: ABSTRACT          There is provided a faucet assembly which includes structure defining a fluid passageway, valve means to close and open the fluid passageway, a shaft for operating the valve means, cam means on the shaft, and a switch operated by the cam means.  The cam means and switch are arranged such that when the valve means closes the fluid passageway the switch is "off", and after the shaft has rotated through a small angle in the direction to open the valve means the switch is "on".  Resilient stop means is provided to arrest rotation of the shaft at a position wherein the passageway is fully open, the stop means being such as to allow limited further opening rotation of the shaft upon application of additional torque.  The said cam means is shaped to again cause the switch means to turn "off" when the shaft has undergone said limited further rotation.

Abstract: ON-LINE REGENERATION OF HYDROTREATING CATALYST     Abstract A hydrotreating catalyst is regenerated as it concur-rently hydrotreats a hydrocarbon fuel by introducing a low concentration of oxygen into the catalyst bed either con-tinuously or periodically.  At low oxygen concentrations the carbon deposits on the catalyst are burned off without harming the catalyst and without significantly affecting the hydrotreating process.  In a preferred embodiment the hydrotreating process is hydrodesulfurization, and regener-ating is done periodically with oxygen concentrations between 0.1 and 0.5 volume percent.

Abstract: "HORIZONTALLY ROTATING BLADE-TYPE CONDITIONING DEVICE FOR  SWATHERS"          ABSTRACT OF THE DISCLOSURE         A frame assembly mounted in the windrow discharge area on a swather or windrower on which a plurality of hori-zontal assemblies, are mounted thereto.  On these assemblies are mounted fraying and cutting blades.  These blades are operated at a required speed to fray and distort the tips of the stubble and/or cut and reduce the length of the straw of the standing stubble so as to ensure that the supportive strength of the straw is not exceeded by the weight of the swath or windrow placed upon it.  This will eliminate any dis-tortion or buckling of the remaining conditioned standing stubble straws.  A windrow delivery plate is mounted on the swather frame assembly within the windrow discharge area.          This plate assures delivery of the windrowed material onto the swath support fingers which effects a gradual release of the windrowed material onto the remaining standing frayed and con-ditioned stubble directly behind the frayer conditioners track of travel in the field.  The conditioned stubble height is con-trolled by an axle type gauge wheel assembly.

Abstract: FUEL INJECTION PUMP                   ABSTRACT OF THE DISCLOSURE       A single plunger distributor type fuel injection pump for multi-cylinder internal combustion engines having improved features for preventing cavitation in the fuel distribution passages upon fuel cutoff and for providing a uniform residual fuel pressure in the idle fuel distribution passages.  The pump does not have the usual delivery valve for maintaining a high residual fuel pressure in the distribution passages.  In-stead, the passages upon injection termination drain into a spill chamber, the pressure within which builds up to resist fuel flow from the passages and minimize cavitation therewithin. The spill chamber pressure is relieved by a bleed passage opening into the low pressure fuel supply chamber.  The pressure in the idle fuel distribution passages is maintained at a low predetermined level by connection of the passages to the fuel supply chamber between injection intervals.

Abstract: ABSTRACT:          "Method of making monocrystalline ternary semiconductor material".     A significant problem in making monocrystalline ternary semiconductor compound material, for example cadmium mercury telluride, is to produce useful quantities of the material which have electrical properties within a narrow band of values, and this depends on the material having a composition within a narrow range. Monocrystalline cadmium mercury telluride may be made by preparing a melt of the material, quenching this melt so as to produce a poly-crystalline ingot 16, sealing the ingot 16 in an ampoule 13, and then forming a molten zone 20 at one end of the ingot 16 and passing this molten zone through the ingot 16 so as to form monocrystalline cadmium mercury telluride 21. The width of the molten zone 20 is from 25 to 40% of the length of the ingot 16.

Abstract: Abstract of the Disclosure Uniform protective coatings are deposited on components with a high strength bond by utilizing a supersonic plasma stream and a transferred arc sys-tem of selectively reversible polarity.  By maintaining plasma stream velocity at a sufficiently high Mach number, and using stream temperatures and static pressures which establish a shock pattern characteristic that diffuses the arc, the workpiece is made cathodic relative to the plasma gun at predetermined in-tervals.  This creates a sputtering effect in which electrons and atoms are ejected from the workpiece despite the impacting plasma flow and the ambient pressure level.  This sputtering action is undertaken to clean the workpiece once it is sufficiently heated and to cause intermingling of molecules of the substrate material with molecules of a deposition powder injected into the plasma flow.  This preparatory deposition, together with the clean workpiece surface, enables a subsequent buildup of securely bonded and highly uniform material.
