Title: Permeable nozzle method and apparatus for closed feeding of molten metal into twin-belt continuous casting machines
Inventor: SZCZYPIORSKI WOJTEK
IPC: B22D11/06
Filed: 1990-10-23
Abstract: Method and apparatus for the feeding of molten metals through nozzles having gas-permeable walls, cooperating with twin-belt continuous metal-casting machines.  The closed-channeled, multi-passaged nozzles have gas-permeable refractory walls, allowing the escape of gases that may be dissolved in the molten metal and become expelled or liberated from it while the molten metal is flowing through the passageways in the nozzle.          Gaseous voids in the continuously cast product are thereby avoided, notably in aluminum casting as shown by experimental results to date.  The nozzles are made from gas-permeable refractory material having interconnected porosity -- that is, interconnected void interstices -- extending through the nozzle walls.          The interconnected void interstices are of sufficient size for allowing the passage of hydrogen gas through the walls, while being sufficiently small for preventing the leakage of molten metal.  The gas-permeable refractory material is relatively non-wettable by the molten metal.  For example, the nozzles are made of fibrous sintered refractory material -- for instance, fibers of alumina or silica intertwined and cohered within a major volume-percentage of interstitial voids, which provide the interconnected porosity.  Such fibrous material displays high resistance to thermal shock.  It is relatively compliant to nozzle clamps, with consequent resistance to breakage, while the coefficients of thermal conductivity and thermal expansion of such fibrous refractory material are advantageously low.

Title: Throttle Actuator Safety Method for Automated Transmission
Inventor: COTE WILLIAM F
IPC: B60W50/02
Filed: 1990-12-10
Abstract: A safety method is provided for use with control systems for vehicles such as trucks, and in particular for electromechanical controls (10) that assist the driver in shifting the gears (12), operating the clutch (16), and in actuating the throttle (22, 24, 26) by remote control.  The method, which is for use in a vehicle's throttle-actuator subsystem (26A), utilizes a transmission control processor (42A) and a throttle control processor (42B).    The method ascertains whether, when the driver of the vehicle removes his foot from the accelerator pedal (24A), control of the fuel pump (26C) returns to the idle governor as it should.  The flow of fuel is stopped if it does not return properly.  Also, a method is provided that monitors the throttle actuator (26A) to insure that it accurately follows throttle commands such as the position of the accelerator pedal (24A).

Abstract: ABSTRACT The present invention is a process for prefractionating a pressurized, helium-containing feed gas mixture (typically containing helium, natural gas and nitrogen) to produce a helium-enriched stream which comprises the following steps:  (a) the pressurized, helium-containing feed gas mixture is liquefied and subcooled by indirect heat exchange; (b) the liquefied, subcooled,  pressurized, helium-containing feed gas mixture is expanded whereby it is partially vaporized, thus producing a partially vaporized frationation feed stream; (c) the partially vaporized frationation feed stream is stripped in a cryogenic distillation column thereby producing as an overhead, the helium-enriched stream, and a bottoms liquid, the helium-lean stream; and (d) the cryogenic distillation column is reboiled by vaporizing at least a portion of the helium-lean stream.     The present invention is also applicable as an improvement to a process for the production of a crude helium product (i.e., > 30 vol% helium).

Abstract: A method of removing water from lubricants, coolants and the like consisting of the following described steps. Firstly, pass lubricants through a heater at a predetermined flow rate to  decrease  its  viscosity.    Secondly,  pass  the  heated lubricants through a vertical separation vessel which agitates the lubricants such that water entrained in the lubricants is released as steam. Thirdly, recirculate the heated lubricants repeatedly through the separation vessel at a recirculation flow rate that exceeds by many times the flow rate through the heater, thereby improving the degree of separation of water from the lubricants with each pass through the separation vessel.   Fourthly,  draw lubricants periodically from the separation vessel as the flow rate through the heater permits.

Abstract: AN IMPROVED METHOD AND APPARATUS FOR COMPILING CODE IN A COMPUTER SYSTEM HAVING A LIMITED NUMBER OF REGISTERS                           ABSTRACT      Computer  software developers have  avoided using register oriented linkage conventions  in systems having a limited number of registers where the programs to be compiled may include an indeterminate number of parameters of differing types.  By creating a formal parameter descriptor with each call being processed that includes an indeterminate number and type of parameters, the program may be compiled using a register oriented linkage convention.  The formal parameter descriptor  is  located  in  a  location  accessible  to  the executing subprogram but unaffected by it.  The invention is particularly useful for compiling unprototyped C language programs using processors having limited registers such as the Intel? 80x86 processors.

IPC: B65B63/02
Filed: 1992-07-29
Abstract: The present invention provides a method of compacting a sheet article, for example an article of underwear, to produce a stable, substantially rigid, compacted article. This reduces space required for storage and distribution and facilitates packaging of the article. Compaction is effected by planing the article, or a plurality of articles, in a mold cavity, and subjecting them to elevated pressure for a certain time.      The pressure and time are selected to compact the article sufficiently for form the stable, rigid body, but simultaneously not being so great as to either damage the article or compact it so much that water or other liquid is required to recover the article from its compacted state to its original state.
