Abstract: ABSTRACT OF THE DISCLOSURE:         The invention relates to a process for simulta-neously producing fuel gas and process heat from carbona-ceous materials containing sulfur and dust.  In this process, the gasification of carbonaceous materials is carried out at a pressure of up to 5 bars and a temperature comprised between about 800 and 1100°C by a treatment with oxygen-containing gases in the presence of steam in a cir-culation fluidized bed defining a gasifying stage, and about 40 to 80% of the carbon contained in the starting carbona-ceous materials are thus reacted.  Sulfur compounds are removed from the resulting gas in a fluidized state at a temperature comprises between about 800 and about 1000°C, and the gas is then cooled and subjected to dust collection. Finally, the gasification residue together with the by-pro-ducts which have become available in the purification of the gas are fed to another circulating fluidized bed defining a combustion stage, and the remaining combustible constitutent are burnt there with an oxygen excess of 5 to 40%.  This pro-cess has a high flexibility regarding the conversion of the energy content of the starting material into fuel gas and process heat so that it permits a quick adaptation to the requirement for energy in a given form.

Abstract: ABSTRACT OF THE DISCLOSURE       There is disclosed a method of using an exhaust gas catalyst for treatment of exhaust gases developed by burning a hydrocarbon based fuel in an internal combustion engine.  These exhaust gases contain varying amounts of unburned hydrocarbons, carbon monoxide and oxides of nitrogen depending upon the operating conditions of the internal combustion engine. This specification teaches the use of an improved catalyst composition in which a support medium is provided for supporting the catalyst system, the support medium having an upstream support portion and a downstream support portion over which the exhaust gases pass in succession.  The upstream support portion of the support medium has palladium deposited thereon and the downstream support portion of the support medium has tungsten deposited thereon.  The catalyst system has particular utility as a three-way catalyst operating at approximately stoichiometric conditions or as a catalyst for use in conjunction with the fast burn engines or as an oxidation catalyst.

Abstract: ABSTRACT OF THE DISCLOSURE          An independent rear wheel suspension for a motor vehicle having front wheel drive includes a wheel support member, and two laterally extending control arms pivotably connected  at  their  outboard  ends  to  the  wheel  support member and at their inboard ends to the vehicle chassis.          The two laterally extending control arms are longitudinally and  vertically spaced  apart.   One  arm has  an  integrally formed spring seat  which  seats  a  coil  spring  interposed between the arm and the vehicle chassis.  A trailing arm is rigidly connected to the wheel support member and has its front  end  connected  through  a resilient  bushing.   The resilient bushing  has  an  outer  sleeve  coaxially mounted about an  inner  sleeve with  layers  of bonded elastomeric material  and  coaxial  rings  interposed  therebetween  and bonded to the inner and outer sleeves.   In addition, the suspension can be constructed to control toe-in of the rear wheel during jounce or recession of the rear wheel.   The central  axis  of  the  inner  and  outer  sleeve  are  angled rearwardly and inboard.  The outer sleeve is axially fixed to the front end of the trailing arm and can axially move against the resilient forces of the elastomeric material.          As the wheel recesses, the bushing allows the front end of the trailing arm to move inboard and promotes the wheel to toe-in during recession.

Abstract: ABSTRACT OF THE DISCLOSURE     The  invention  features   methods  and  apparatus   for obtaining  silicon  carbide  whiskers  on a continuous basis.          Coked rice  hulls or other carbon and silicon containing feed materials are  continuously fed  to a  conversion zone  in an unagitated state in  order to  promote whisker  growth.  The conversion zone  is continuously  purged, preferably  with an inert  gas  such  as  nitrogen.   The  purging gas is vented directly out of the conversion zone and  carries away gaseous reaction products  and impurities, prevents  oxidation of the whiskers and  keeps glasses from condensing and depositing on the  furnace surfaces,  The  feed materials are  fed in a dry state to the conversion zone  in order to prevent erosion  of the furnace walls.  After conversion and cooling the whiskers are separated  from the mass of  particulate silicon carbide.          The whiskers find use as reinforcements.

Abstract: ABSTRACT OF THE DISCLOSURE    An a.c. input circuit for converting a sensed a.c. voltage into a logic level voltage includes a rectifier for converting the sensed a.c. voltage to a d.c. voltage which is supplied through a coupling impedance to the light emitter of an optical isolator.  While the a.c. input voltage is below a first predeter-mined voltage, a switchable low impedance circuit path in parallel with the light emitter is rendered conductive to maintain a low impedance across the light emitter to prevent the light emitter from becoming conductive.  A switchable high impedance circuit path in parallel with the switchable low impedance circuit path becomes conductive once the sensed a.c. input voltage reaches the predetermined voltage to drive the light emitter into hard conduction.  The switchable high impedance circuit path remains conductive until the sensed a.c. input voltage drops below a second predetermined value, at which point the light emitter is turned off and the switchable low impedance path becomes conductive.

Abstract: BOILER WATER TRIP SYSTEM               ABSTRACT OF THE DISCLOSURE          A boiler water trip system comprises a flow transmitter for sensing a flow of water into a boiler, a pressure transmitter for sensing a pressure of steam entering a first stage of a turbine powered by the boiler, a unit power transmitter for sensing the power generated by the turbine, a feeder water temperature transmitter and a drum level transmitter for sensing the level of water in a steam drum connected to the boiler.  Function generators are connected to the pressure and unit load transmitters for obtaining a measure of flow out of the boiler.  The higher of the two flow values are compared with the feed water flow to the boiler to generate an error signal which is integrated.  The integrated error signal corresponds to a calculated boiler water level amount.  If the boiler water level rises above or falls below set limits and, simultaneously, a drum level rises above or falls below said amounts as determined by the drum level transmitter, a tripper is activated to trip the boiler.  The flow error signal and the integrater are connected to a unit for determining whether the drum level has risen above or fallen below its set limits to push the flow error signal toward a correct value when there is no actual flow error between the feed water to the boiler and flow out of the boiler.

Abstract: ABSTRACT   In the present invention, a frame, mounted above the platen of a typewriter or a word processing machine, supports a drive roller in contact with the platen.  This drive roller is also in contact with a tray-moving mechanism, supported above the drive roller.  A plurality of trays carried in the frame are supported above the platen so as to hold sheets of paper or envelopes vertically between trays and in alignment with the sheet insert side of the platen.  When the platen is turning backward, the drive roller actuates the tray-moving mechanism, causing a tray to move, separating it from the next adjacent tray and permitting a sheet of paper which had been placed therebetween to drop into position against the platen.          Thus the sheets are fed automatically against the platen when the platen rotation is reversed.
