Abstract: ABSTRACT    The invention comprises a packer design for use in high temperature well bores.  The packer is set by pres-suring the well fluid through a tubing string, which moves a piston and shoe assembly on the packer mandrel, compressing a non-elastomeric high temperature packer element.  The piston and shoe assembly combination is maintained in position after pressure is decreased, and the packer element is maintained in a compressed state by belleville springs which compensate for the lack of resiliency of the non-elastomeric packer element.

Abstract: METHOD OF POLYMERIZING HYDROXYL ENDBLOCKED POLYDIORGANOSILOXANE USING QUATERNARY AMMONIUM      CARBOXYLATE-CARBOXYLIC ACID CATALYST            Abstract Hydroxyl-endblocked polydiorganosiloxane oligomer is polymerized through the use of a catalyst mixture of quaternary ammonium carboxylate and carboxylic acid.  The method heats the mixture of oligomer and catalyst to a temperature in the range of from 90°C to 150°C, removing water from the mixture, until the desired degree of condensation is achieved.  When cooled, the product is a stable polydiorganosiloxane of increased molecular weight. The catalyst can be inactivated by heating and removing volatile byproducts.  One embodiment of the method adds an acidic or neutral reinforcing filler to the mixture before polymerization to yield a storage stable silicone polymer-filler mixture which is useful in a manner similar to conventionally produced silicone polymer-filler mixtures.

Abstract: ABSTRACT            An acoustic microscope comprises an acoustic trans-ducer that performs both generation and detection of an acoustic wave.  A sample holding member mounted opposed to an acoustic wave transmitting and receiving surface of the transducer holds the sample in an acoustic wave propagating medium and provides behind the sample a layer with an acoustic impedance unequal to that of the sample.  The sample holding member can be moved laterally.  Acoustic waves reflected from front and rear surfaces of the sample and acoustic waves reflected from a surface of the sample holding member in the absence of the sample are detected to measure amplitudes and return times of the reflected acoustic waves.  The velocity of sound through a sample of unknown thickness and the acoustic impedance of the sample can be determined from the measured values.  The arrangement combines the advantages of the conventional transmission and reflection types of acoustic microscope.

Abstract: ABSTRACT     A repeatably rejuvenating filtration system of the pneumatic hydro-pulse type is disclosed as including the feeding of a solid/fluid feed slurry to be filtered into operative engagement with the interior porous wall surfaces of a plurality of open ended tubular filter elements so that filtrate passes outwardly through the walls of the filter elements and the solids are collected as a cake on the interior wall surface.  The cake of solids on the interior wall surface is subjected to an axial discharge fluid flow through the interior of the filter elements along the length of the cake for removal of the cake axially along the interior of the filter elements.  The system includes an arrangement for providing a pressure actuated pulse of fluid that may operate through the cylindrical walls toward the axial bore of the filter tubes to dislodge the filtered material, and may operate substantially simultaneously with the axial discharge flow for conducting the dislodged filtered material from the open ended bores.   The versatility of the system enables the use of a recirculating arrangement that is effective to concentrate the solids content and control the thickness of the cake deposit.

Abstract: SLACK ADJUSTER FOR A DISC BRAKE                  Abstract of the Disclosure A slack adjuster is for a disc brake of the type which includes a disc mounted for rotation about an axle and a caliper brake having a housing mounted on the axle in alignment with a friction surface of the disc.  A braking piston is mounted in the housing for axial movement toward and away from the friction surface of the disc.  Brake actuation produces rotating movement of a powershaft mounted in the housing which will in turn produce a corresponding axial movement of the braking piston through a non-rotating powershaft nut.  An adjusting sleeve is between the piston and the powershaft nut and is threadably coupled to the piston and capable of rotation relative thereto to adjust the axial position of the piston.  The adjusting sleeve is capable of rotating in a direction which will cause the piston to be adjusted toward the disc and is prevented from rotating in the opposite direction by a one-way clutch shaft between the adjusting sleeve and the housing.  A lost motion element allows rotation of the powershaft to produce corresponding rotation of the adjusting sleeve after the piston has moved toward the disc through a desired running clearance without having made any frictional contact therewith and employs a force limiting clutch element to prevent corresponding rotation of the adjusting sleeve when the powershaft is rotated in a direction to produce movement of the piston away from the disc.  The clutch shaft can be selectively operated in both directions for initial adjustment of the adjusting sleeve.

Abstract: Abstract of the Disclosure A pressure control valve for the compressed air brakes of a railway vehicle includes a triple pressure control valve with a constant pressure chamber, a selector valve and a selector reservoir.          Upon the occurrence of pressure reductions in the main brake line for service braking, the selector valve remains at rest.  When stronger pressure reductions in the main brake line occur, the selector valve evacuates the selector reservoir which lags in relation to the main brake line pressure as result of the force exerted by a pre-stressed spring until a specific minimum pressure is attained by a retention valve.  In a subsequent brake release, the selector valve will produce a pressure balance between the constant pressure chamber and the selector reservoir to facilitate the brake release process and a balancing or proportioning of the pressure control valve at an optionally reduced normal pressure head in the main brake line.  The selector valve includes a piston retained in a middle position by a spring buffer and by two valves positioned on both sides of the piston and spring loaded in their respective closing directions.  On one side, the piston is loaded by the main brake line pressure and on the other side by the pressure in the selector reservoir.

Abstract: TISSUE PAPER     ABSTRACT            Soft, absorbent paper webs and processes for making them. In the process, an aqueous dispersion of the papermaking fibers is formed into an embryonic web on a first foraminous member such as a Fourdinier wire. This embryonic web is associated with a second foraminous member known as a deflection member. The surface of the deflection member with which the embryonic web is associated has a macroscopic monoplanar, continuous, patterned network surface which defines within the deflection member a plurality of discrete, isolated deflection conduits. The papermaking fibers in the web are deflected into the deflection conduits and water is removed through the deflection conduits to form an intermediate web. Deflection begins no later than the time water removal through the deflection member begins. The intermediate web is dried and foreshortened as by creping. The paper web has a distinct continuous network region and a plurality of domes dispersed throughout the whole of the network region.

Abstract: VARIABLE DELAY LINE             Abstract of the Disclosure A delay line circuit provides variable delay and phase shift to electric signals propagating along the delay circuit.  The circuit is formed of a set of varactors constructed either as varactor chips or as a set of mesas upstanding from a gallium arsenide substrate.  A ground plane interconnects bottom terminals of the varactor chips while a strip line conductor interconnects top terminals of the varactor chips.  In the case of the mesa configuration, a metallized layer covers the regions between the mesas without contacting the base portions of the mesas.  The strip line conductor makes contact with the respective mesas via a set of metallic posts upstanding from respective ones of the mesas.          Dielectric material may be inserted between the strip line conductor and the metallic layer to position the strip line conductor relative to the metallic layer, which layer serves as a ground plane in a transmission line comprising the strip line conductor.
