Abstract: A sterilizing unit for air ducts having an aluminum housing and at least one UV emitting probe extending downward into the duct. The upper surface of the unit overhangs the side walls for easy installation into the duct. At least one UV emitting probe in connection with the circuitry extends downward into the air duct. There is a light sensor, or monitor, that extends from the upper side of the unit to a point near the probe in order to provide a visual indication of the condition of the UV probe without exposure to the UV light. An on/off switch on the upper surface of the device allows for safety in servicing the sterilizing unit.

Abstract: A method and system for determining the effectiveness of operation of a branch of a branch unit in a processing system the processing system including at least one performance monitor counter (PMC) and at least one monitor mode control register (MMCR) to configure the operations of the at least one of the PMC, includes accumulating count data during branch unit operation with the at least one during a predetermined sampling period, and determining effectiveness of branch prediction based on the accumulated count data.

Abstract: A method and system for determining the efficiency of operation of a dispatch unit in a processing system, the processing system including at least one performance monitor counter (PMC) and at least one monitor mode control register (MMCR) to configure the operations of the at least one PMC, includes counting a number of instructions dispatched by the dispatch unit during a predetermined sampling period, counting a number of times a predetermined number of instructions are dispatched by the dispatch unit per cycle during the predetermined sampling period, and determining the efficiency of the dispatch unit according to the counted number of instructions and the counted number of times the predetermined number of instructions are dispatched by the dispatch unit.

Abstract: A method of high retained strain forging is described for Ni-base superalloys, particularly those which comprise a mixture of .gamma. and .gamma.' phases, and most particularly those which contain at least about 30 percent by volume of .gamma.'. The method utilizes an extended subsolvus anneal to recrystallize essentially all of the superalloy and form a uniform, free grain size. Such alloys may also be given a supersolvus anneal to coarsen the grain size and redistribute the .gamma.'. The method permits the manufacture of forged articles having a fine grain size in the range of about ASTM 5-12 (5-60 .mu.m).

Abstract: The invention provides finely divided vulcanized rubber having a particle size of generally less than 20 microns for re-use in the rubber industry. Vulcanizates produced from compositions containing the finely divided vulcanized rubber, either as the sole rubber component or in admixture with unvulcanized rubber, have properties significantly better than those of vulcanizates of similar compositions containing conventional reclaimed rubbers. Vulcanized rubber is converted into the finely divided rubber by the steps of (1) contacting vulcanized rubber with a fatty acid, (2) contacting the product of step (1) with a solid alkali and (3) forming a dispersion of the product of step (2) with a liquid which dissolves the alkali but does not affect the rubber. Alternatively, the finely divided vulcanized rubber results from the steps of (1) contacting the vulcanized rubber with a liquid effective to swell the rubber and thereby weaken it e.g.

Abstract: A plunger assembly for moving a batch of rod-like articles, principally from a conveyor into a tray, is provided with locating means, such as a flexible strip, which is movable with the plunger and which exerts light pressure on the top of a batch to control the articles as they are transferred.

Abstract: A magnetic recording element of the type including a base and a coating upon a surface of the base, the coating comprising magnetic particles dispersed in a polymeric binder and a lubricant, the improvement comprising a lubricant chosen from the group consisting of a trifluoride of cerium, lanthanum, praseodymium, neodymium, and samarium.

Abstract: Apparatus is provided for automatic production testing of large digital circuit modules. A test station, under computer control, applies test bit patterns and clock pulses to the module under test, analyzes the resultant outputs, and isolates any fault found to one or several IC's. The test station contains power supplies and air cooling for the module, and a keyboard display and printer for use by the test operator. Test programs are developed off-line and are loaded from magnetic tape into a disk pack where they are available to the computer. The flip-flops on the module to be tested are used as an extension of the test station through the addition on the module of circuitry to allow the flip-flops to be reconfigured from their normal circuit configuration into a shift register connected at one end to one of the module connector pins.

Abstract: A hydraulic actuator arrangement has a pair of double acting actuator devices coupled together for movement in unison. Each device has two control valves respectively operable to cause the device to move in opposite directions. The four control valves are resiliently coupled so that both actuator devices are normally energised simultaneously. Each control valve has an associated pressure relief valve so that failure of any one of the control valves permits the pressures on either side of the associated actuator device to be equalized.

Abstract: Granular materials are separated on a dry pinched sluice separator having at its discharge end a conical concave surface. The material to be separated is allowed to flow downwardly over the separator chute under gravity and fluidization and the so separated materials traverse the concave surface.

Abstract: Article dispensing apparatus for use in a hotel room or the like includes an article support such as a rotatable carousel having a plurality of compartments. Access to any individual compartment is attained by means of a door on the apparatus. A detent means prevents the door from being opened unless the carousel is in a dispensing position. Opening of the door to attain access to an article causes an interlock to latch the carousel in the dispensing position and simultaneously produces a record of the value of an article in the compartment opposite the door when the door was opened.

Abstract: An electric arc furnace powered by direct current includes three electrodes of negative polarity depending into the vessel from above and a plurality, e.g. six, of electrodes of the opposite polarity mounted in the hearth of the vessel. Switching means are provided selectively to connect one or more of the vessel electrodes in circuit whereby to regulate the lobes of power dissipation from the dependent electrodes as required. The vessel electrode design is such as to enable the furnace to be tapped whilst maintaining a reservoir of metal for the succeeding charge.
