Abstract: In one embodiment, a process is provided for treating virgin poly(arylene sulfide) resins, wherein a heated polymeric slurry, comprising a virgin poly(arylene sulfide) resin and water is contacted by an acidic treating solution comprising an acidic component and an aqueous component, wherein the amount of the acidic component in the acidic treating solution is less than the amount necessary to result in a partial curing of the virgin poly(arylene sulfide) resin. In a second embodiment, the process is provided for treating a virgin poly(arylene sulfide) resin, wherein the virgin poly(arylene sulfide) resin is slurried in an acidic treating solution comprising an acidic component and an aquoues component and the concentration of the acidic component in the aqueous treating solution is less than the amount necessary to result in a partial curing of the virgin poly(arylene sulfide) resin. The polymeric slurry is then heated to an elevated temperature, below the melting point of the virgin resin, while in the substantial absence of a gaseous oxidizing atmosphere.

Abstract: The coffee-making apparatus has an infusion chamber (1) which has a filling valve opening (2), a filling nozzle (3), an outlet valve opening (4) to an outlet (5), an opening (6) to a coffee pipe (7) and an inlet (8) for the infusion water. A stationary bearing sieve (9) and a valve piston (10), controlling the infusion process, are arranged displaceably in the infusion chamber. The valve piston (10) is arranged outside the basic area of the bearing sieve (9) and the outlet valve opening (4) extends above the bearing sieve (9) transversely to the longitudinal axis of the valve piston (10). By this means, on the one hand full utilisation of the filter area is achieved and, on the other hand, the valve piston (10) is prevented from removing appreciable amounts of heat from the infusion water. Cleaning of the infusion chamber (1) is also facilitated by the abovementioned design. <IMAGE>

Abstract: An arriving coin (10') of too large a diameter runs with one edge onto a run-on ramp (44). The raising of the coin (10') also causes the raising of the lower strand (12'') of a conveyor band (12') conveying a stream of coins. The raising brings about a lateral deflection of the lower strand (12'') in the direction of the arrow, the coin (10') to be separated out also being displaced laterally, thereby slipping off from the left-hand supporting edge (22) and tipping into a sorting-out orifice (14). The conversion of the raising movement of the lower strand (12'') into a lateral deflection is brought about by a guide roller (28) which is mounted on an arm (26) pivotable about an axis (50) and which is prestressed against the lower strand (12'') by means of a spring (30). Because the coin (10') to be separated out runs onto the ramp (44), a build-up of coins conveyed thereafter is prevented, thereby guaranteeing a high uniform output of the apparatus. The apparatus makes it possible to separate out coins of too small and of too large a diameter. <IMAGE>

Abstract: A liquid-crystal display apparatus comprising two substrates (1, 2) opposing each other and having elec­trodes (3, 4) formed on the opposing surfaces (1a, 2a), at least one of the electrodes (3, 4) being transparent, a nematic liquid crystal layer (8) interposed between the substrates (1, 2) and having pre-tilt angle ϑ of greater than 1° with respect to the surfaces (1a, 2a) of the substrates (1, 2), and having a twisting angle of 180 to 360° from the first substrate (1) to the second substrate (2), a first polarizer (9) arranged on that side of the first substrate (1) which faces away from the electrode (3) formed thereon, a second polarizer (11) arranged on that side of the second substrate (2) which faces away from the electrode (4) formed thereon, and an optical retardation member (10) or a combination of an optical retardation member (10a) and a quarter-­wave plate (10b), each located between the polarizers (9, 11). The value of R = Δn·d·cos⁺ϑ ranges from 0.4 to 0.8, where Δn is the optical anisotropy of the nematic liquid crystal material (8), d (µm) is the thickness of the liquid crystal layer (8), and ϑ is the pre-tilt angle of the liquid crystal material (8). The value of R′ = Δn′·d′ ranges from 0.22+0.55m to 0.42+0.65m, or from 0.47+0.55m to 0.67+0.65m (m = 0, 1, or 2), where Δn′ is the optical anisotropy of the optical retardation member (10) and d′ (µm) is the thickness of the optical retardation member (10). Owing to the optical retar­dation member (10) located between the polarizers (9, 11), and also to the specific values of R and R′, the apparatus can perform high-quality monochrome display with great background whiteness and high image contrast.

Title: Foamable polymerisate based on polyphenylene oxide and a vinylaromatic compound, process for its preparation and use thereof
Inventor: SPEIKAMP HANS-DIETER DR
IPC: C08F291/00
Filed: 1989-07-27
Abstract: Hitherto, heat distortion resistant foams based on polyphenylene oxide and a vinylaromatic compound have been prepared by polymerising the vinylaromatic compound in the presence of polyphenylene oxide. The finished polymer blend is then granulated, mixed with the blowing agent in the extruder and subsequently expanded. This process is complex and expensive. In the process according to the invention, the foamable polymer is prepared in a one-step process, ie. the mixing with the blowing agent takes place during the polymerisation. In addition, caking on the reactor walls is prevented by adding the starting materials in a specific sequence, which results in an increase in yield. Expansion then follows. The foams produced from the foamable polymers are preferably employed for thermal insulation.

Abstract: A molded bonded fibrous sheet is completely sealed in a facing sheet during the molding operation. A fibrous layer containing uncured binder is placed in a mold. Facing sheets covering the major faces of the layer are included. Under the application of heat and pressure the mold faces form the layer into the desired shape and thickness, while at the same time the cover sheets and fibrous layer are trimmed by cutting edges. A shoulder connecting the cutting edge of one of the molds to the mold face forces the adjacent sheet into contact with the other sheet, and the cured binder seals the sheets to each other and to the severed edge of the fibrous layer, thereby encapsulating the fibrous layer within the cover sheets. A similar arrangement can be utilized in connection with a press to adhesively apply a facing sheet to the body and edge portion of a previously formed substrate.

Abstract: An integral phase shifting network (215,216,217) of a transmitter filter (104) provides a means to reduce the size and increase the efficiency of an antenna coupling network. The network to shift the phase of the transmitter filter (104) is printed by depositing conductive material directly on a ceramic block (230) using low-loss circuit elements and can be tuned easily by removing conductive material if required in certain applications. By utilizing an integral phase shifting network (215,216,217), either transmit filter (104) or receive filter (112) having a highly reactive and capacitive out-of-band impedance in the receive or transmit band, respectively, can be connected to a common antenna port without external transmission lines.

Abstract: An output buffer is described which includes a plurality of pull up transistors (54) connected in parallel and/or a plurality of pull down (64) transistors connected in parallel. A desired amount of resistance (53, 63) is included in the path connecting the gates of the pull up transistors, and in the path connecting the gates of the pull down transistors, thereby providing a distributed RC network causing pull up and pull down transistors to turn on in sequence. This the rate of change of the pull up and pull down current constant, thus reducing ground and Vcc bounce. In another embodiment, a single pull up transistor and/or a single pull down transistor is used. The single transistors have a relatively high gate resistance such that along the channel width of the transistor, the gate capacitance and the gate resistance operates as a distributed RC network. In this manner, portions of the channel begin conducting sequentially, as is the case where a plurality of pull up and pull down transistors are used.
