Abstract: ABSTRACT OF THE DISCLOSURE   A single chip microcomputer having an instruction decoder and a function circuit for example, ROM, RAM, ALU, or the like, is further provided with a parallel input shift register, which receives data from the instruction decoder.  Output signals from the shift register are transferred to an external terminal or to a data bus by means of gates upon receipt of a testing mode control signal from a testing mode control circuit.  By means of the testing mode control signal, the test output signal of the instruction decoder is sent to the external terminal only during testing by means of direct testing of the instruction decoder, testing is more simplified and testing time is drastically shortened, resulting in an increase in production and a decrease in manufacturing cost.

Abstract: ABSTRACT OF THE DISCLOSURE         Method and means are provided herein for entraining gas as a blowing agent in a thermoplastic melt to provide foamed thermoplastic extrudate.  The method includes providing an extruded flowing mass of thermoplastic melt.  The flow of the melt is constained into a tubular configuration over a finite distance.  An annular sheet-like flow of gas is impinged under pressure on the tubular configuration of melt substantially transversely of the direction of flow thereof to entrain the gas in the melt.  Subsequently the melt with entrained gas is returned to a flowing mass configuration, where the flow rate and temperature of the flowing mass with entrained gas is controlled to optimum values for subsequent extrusion.  Finally, the flowing mass, with entrained gas is extruded to produce the foamed thermoplastic extrudate.  The cell pressures achievable by the present invention are higher than the cell pressures achievable by fluorocarbon blow-ing agents and therefore, less brittleness is an intermediate benefit achieved by the present invention in the ultimate extruded foam products. The oriented foams have been stretch oriented 1.5 times initial dimensions in both the machine and transverse directions of extrusion and this has been found to be highly satisfactory in producing foams of reduced brittleness and enhanced structural strength.

Abstract: "HEAVY-DUTY TRIP MECHANISM FOR GROUND WORKING IMPLEMENTS"      ABSTRACT OF THE DISCLOSURE         Normally, spring loaded trip mechanisms increase in resistance and pressure as they move rearwardly.  This device includes a swing arm above the shank with a roller engaging the upper surface of the shank.  The tension springs extend from the swing arm to the upper end of the shank arm near the pivot thereof to the frame and are ad-justable so that the initial tripping pressure may be set.          Once this pressure is reached, the shank and arm move rear-wardly causing the roller and swing arm also to be forced rearwardly thereby extending the springs.  The geometry of the swing arm and springs, together with the shank is such that once the tripping pressure is reached and the shank commences to move rearwardly, the resistance drops rapidly instead of increasing thus letting the arm clear the object without any increase of contact force.  Once cleared, the springs return the shank to the working position.

Abstract: MANIPULATOR APPARATUS WITH ENERGY EFFICIENT CONTROL             Abstract Manipulator apparatus is provided with an energy efficient control arrangement.  The control arrangement in a point-to-point mode of operation utilizes a servo valve to selectively admit fluid from a pressurized source to one end of a cylinder. A piston is slidably mounted within the cylinder and connected to move a manipulator arm that is movable in a plurality of axes.  The servo valve is closed when a predetermined arm velocity is reached and a bypass valving arrangement is opened to  interconnect the ends of the cylinder.  At a predetermined position of the manipulator arm, the control arrangement closes the bypass valving arrangement and the manipulator arm is decelerated as the arm approaches the desired final position.  The pressurized source includes an accumulator and two high pressure check valves that each connect a respective end of the cylinder to the accumulator when the pressure at the respective end of the cylinder exceeds the accumulator pressure to supply pressurized fluid to other axes of the manipu-lator.  The control arrangement compares the decelera-tion of the arm with a reference table of scheduled points representing desired velocity at respective positions to selectively control the opening and closing of the bypass valving arrangement during deceleration.  During repetitive work or repeat cycles of operation, the reference table is modified in accordance with adaptive procedures to provide accurate control of the deceleration of the arm and the point at which the bypass valve is closed to initiate the deceleration.

Abstract: METHOD OF PRODUCING NOVEL SILICON CARBIDE ARTICLES        ABSTRACT OF THE DISCLOSURE   A method of producing articles comprising reaction-bonded silicon carbide (SiC) and graphite (and/or carbon) 18 given.  The process converts the graphite (and/or car-bon) in situ to SiC, thus providing the capability of eco-nomically obtaining articles made up wholly or partially of SiC having any size and shape in which graphite (and/or carbon) can be found or made.  When the produced articles are made of an inner graphite (and/or carbon) substrate to which SiC is reaction bonded, these articles distinguish SiC-coated graphite articles found in the Prior art by the feature of a strong bond having a gradual (as opposed to a sharply defined) interface which extends over a distance of mils.  A method for forming SiC whisker-reinforced ceramic matrices is also given.  The whisker-reinforced articles comprise SiC whiskers which substantially retain their structural integrity.

Abstract: PURIFICATION OF CHLOROSILANES                         ABSTRACT           Chlorosilanes contaminated with boron-containing impurities can be purified by passing the chlorosilane vapor through a silica fixed bed.  Normally the boron level in trichlorosilane is reduced by about 90-99+ % by the use of this process.  The capacities of the silica columns for the purification of trichloro-silane generally are in the range of 1500-2000 pounds trichlorosilane per pound of silica.  The purified chlorosilane is particularly well suited for the production of polycrystalline silicon.  Polycrystalline silicon containing 0.03 ppba (parts per billion atomic) has been prepared from trichlorosilane purified with this process.

Abstract: GATE VALVE STRUCTURE            Abstract of the Disclosure An improved valve seat structure for an expanding gate valve. The valve seat structure comprises a "floating" seat ring (60) which is loosely received in an annular seat pocket (52) surrounding the flow passage through the valve and is provided with an axial dimension which exceeds the depth of the seat pocket. The front seat face(61) of the seat ring is disposed ad-jacent the gate assembly (24, 26) and is provided with an annular groove (63) with an annular resilient sealing element (64) therein which protrudes beyond the face of the seat ring and forms a ring of sealing contact area encompassing the flow passage (14) when the gate assembly is expanded there-against. The rear face (66) of the seat ring (60) is also provided with an annular groove (63') and a second annular resilient sealing element (64') therein which protrudes beyond the rear of the seat ring. The two annular sealing elements are disposed coaxial and the inner diameter of the front seal-ing element (64) exceeds that of the rear sealing element (64') so that the front sealing element is therefore located a greater radial distance from the flow passage (14) than is the rear sealing element. Accordingly, when the gate assembly is expanded against the seat ring (60), the annular area of the front face of the seat ring which is exposed to flowline pressure exceeds the annular area of the rear face of the seat ring which is exposed to the flowline pressure whereby the seat ring is pressure energized towards the bottom (54) of the seat pocket (52). The annular resilient sealing elements (64, 64') and bottoms of the annular grooves (63, 63') are provided with cooperating wedg-ing surfaces (80, 94 and 80', 94') which act to wedge the front face sealing element (64) towards the gate assembly and the rear sealing element (67) towards the bottom (54) of the seat pocket. The sealing elements increasing the sealing ability of the valve seat in accordance with increasing flowline pres-sure and permit the valve seat structure to compensate for non-parallel condi-tions between the sealing surfaces of the gate assembly and valve seat and the valve body (12).
