Abstract: Abstract of the Disclosure Phyllosilicate minerals and certain fibrous amphiboles which exhibit in their structure, sequentially, octahedral layers containing magnesium, aluminum and/or iron oxides and tetrahedral layers of silica, are superficially leached with dilute acid to remove the outer octahedral layer under controlled conditions which preserve the basic structural integrity of the mineral sub-strate.  The acid leach exposes silanol groups on the outer silicate layer of the mineral so that they become available to form silicon-to-oxygen-to-silicon-to-carbon bonds through con-densation with organo-silanes.  The condensation of the organo-silane with the conditioned mineral surface 's accomplished by mixing the acid leached silicate mineral with the organo-silane in a suitable solvent system under mild conditions.          The organo-silane may be chosen from either of two classes; those which impart an oleophilic surface to the mineral or those which enable the mineral surface to form additional chemical bonds with reactive sites within certain polymers and prepolymers.  The mineral products of this invention which have been treated to possess oleophilic surfaces are superior additives for rheology control in lubricants, polyolefins, paints and oil well drilling fluids, as well as heat and moisture resistant re-inforcing agents for rubbers; while those mineral products treated to possess surfaces chemically reactive with polymers and per-polymers when incorporated in such systems impart to the finished composites improved mechanical properties and heat and moisture resistance.   1a

Abstract: COMBUSTION APPARATUS UTILIZING AN AUGER HAVING AN INTEGRAL AIR SUPPLY SYSTEM                 Abstract of the Disclosure A combustion apparatus utilizing an auger having an integral air supply system.  The apparatus includes a cylindrical combustion chamber containing a  rotatable auger.  Waste is delivered to one end of the combustion chamber and is conveyed through the chamber by the auger, and ash and the non-combustible residue is discharged from the opposite end while the waste gases are discharged through a cyclone separator to remove fly ash. The auger is composed of a tubular shaft and a hollow spiral flight.  Air is introduced into the downstream end of the shaft and flows through the hollow flight and exits through outlet holes in the flight into the combustion chamber.  A portion of the air is introduced into the mass of waste being conveyed by the auger to provide primary air for combustion, while a second portion of the air is discharged from the flight into the upper zone of the combustion chamber above the level of the waste, to provide secondary combustion of the waste gases.

Abstract: ABSTRACT OF THE DISCLOSURE         An MOS transistor constructed using silicon on sapphire technology in which the channel region can be elec-trically connected either to the source or drain terminal is disclosed.  The transistor is advantageous in that the shift of the threshold voltage of the transistor in the presence of radiation is substantially decreased.  Connecting the channel region of the transistor to the source terminal also substantially reduces what is normally referred to as the "kink" effect in MOS transistors utilizing floating substrate channel regions.  Reducing the sensitivity to radiation and the kink effect results in a transistor having improved electrical characteristics.

Abstract: CLOSED LOOP CONTROL SYSTEM FOR HYDROSTATIC TRANSMISSION                     ABSTRACT     A hydrostatic transmission for accelerating, driving and braking a high inertia load, such as the swing mechanism of a power shovel or crane, includes an engine-driven swashplate-type variable displacement constant speed reversible main hydraulic pump coupled in a closed loop circuit to a swashplate-type fixed displacement variable speed reversible hydraulic motor. A pair of control lever operated pilot pressure modulated pump displacement control valves selectively direct control fluid from an engine-driven fixed displace-ment constant speed charge pump to the stroking pistons of the servo control cylinders on the main pump to thereby control motor direction and speed. The charge pump also supplies replenishing fluid to the main pump/motor circuit through replenishing check valves. A network of three flow control valves is connected across the main pump/motor circuit and to the charge pump outlet to measure the fluid pressure drop across the motor and thus provide a torque feedback signal to modulate the control valves and thereby maintain maximum motor torque for the control lever position selected. A balancing signal is also transmitted from the charge pump to further modulate the control valves and thereby render them insensitive to variations in charge pump pressure appearing in the torque feedback signal.

Abstract: Abstract In a punch press for making metal can tops with closures, respectively, especially those closures of easy-open construction involving an integral but fractured section, cooperative dies are caused in each cycle to perform at a single station first a forming operation, then a peripheral coining step, pref-erably during the last phase of the forming, and lastly a primary and a secondary swaging or "fracture sealing" operation, the latter occurring as the dies separate. The invention, though not so limited, is applicable to production of can tops of the type disclosed in U.S. Letters Patent 3,881,830, for example, and has particular merit in enabling can top production to occur largely at a single station.  It thus conserves manufacturing space as well as lowers cost.

Abstract: Abstract of the Disclosure A fixed displacement pump is connected to deliver operating fluid to a torque converter and to a transmission shift control valve that is operable for selectively coupling working fluid to one or more hydraulically operable shift elements of a trans-mission. A converter pressure regulator valve maintains the pressure of the working fluid at the converter at a predetermined minimum and this pressure prevails generally throughout the system.  When the transmission shift control valve is actuated so as to couple one or more shift elements to the pump which require more than the predetermined minimum pressure for acceptable operation, a pilot flow occurs through the shift control valve to actuate a boost valve which activates a main transmission pres-sure regulating valve so as to cause the pressure of the fluid passing to the one or more shift elements to rise to a level for effecting acceptable operation thereof.
