Abstract: A process for extruding polymer material, in which the material (18) is rapidly compacted and forced through an extrusion aperture (16). The rate of extrusion may be such as to cause rapid heating of the material (18) without melting of the material (18), followed immediately by cooling of the material (18) to retain to a substantial extent the molecular orientation in the material (18) as it passes through the aperture (16). The process is conveniently performed in Conform Apparatus (10, 10 a ) having an extended grip area for the material (18).

Abstract: A power supply control circuit for use in an automobile telephone to which power is supplied in response to a power switch signal and to an ignition voltage. The power switch signal is generated by a power switch in a handset of the telephone. The ignition voltage is produced by turning on an ignition key. The power supply control circuit comprises an emergency switch which manually produces an emergency switch signal. An emergency switch monitor circuit monitors the state of the emergency switch and produces an emergency control signal when it receives the emergency switch signal. Upon the emergency control signal, an ignition voltage control circuit produces the ignition voltage regardless of the condition of the ignition key. Upon the emergency control signal, a power switch control circuit produces the power switch signal regardless of the condition of the power switch. By receiving the ignition voltage from the ignition voltage control circuit and the power switch signal from the power switch control circuit, the automobile telephone can quickly be turned on in an emergency situation.

Abstract: A power operated contact apparatus extends and retracts one or more electrical leads into and out of a cryostat for making and breaking, at a cryogenic temperature, electrical contacts with a superconductive circuit. A pair of rigid elongated leads extend into a cold space of the cryostat which is at or near a cryogenic temperature. A connector is fixed at the inner end of each lead for making electrical contact in the cold space with a mating connector of the superconductive circuit. A guide journals each lead for axial movement and seals against the lead using an elastomeric O-ring coated with a lubricious polymer. A foundation is attached and sealed to the cryostat and to the guide means so that the connector on the inner end of the lead is extendable into making electrical contact with the connector of the superconductive circuit in the cold space. An air cylinder operated four bar linkage extends and retracts the leads to and from making electrical contact with the superconductive circuit in the cold space. The leads are cooled by flowing cryogen from the cryostat through them, which flow is turned off when they are disconnected, and prevented from freezing up outside of the cryostat by a flow of air directed around the leads.

Abstract: In known centrifuges for continuously separating materials of different densities, nozzles for the discharge of the dense material are arranged on the drum shell in the discharge area of the dense material, which nozzles are operatively connected to an adjusting device located outside the centrifuge drum by adjusting members arranged inside the centrifuge drum. The nozzle openings are here opened and closed by means of hydraulic pressure-fluid media. This is not only complicated and costly but also problematic with regard to the sealing of the pressure fluid. In addition, the adjusting members arranged inside the centrifuge drum are not accessible from outside and are therefore also difficult to service and exchange. These disadvantages are removed according to the invention in a particularly simple manner by the adjusting members (4) for opening and closing the nozzle openings (14) being arranged on the outside on the centrifuge drum (1) and by being in operative connection with the adjusting device (6, 9) via mechanical connecting elements (5, 10). …<IMAGE>…

Abstract: Flexible, metallic endless belts for continuous metal-­casting machines usually have the imperfections that are more or less inherent in the parent strip metal from which the belt is made. Belts, as they revolve in the machine, are normally steered through sensing the lateral or side-to-side position of one edge while this edge passes a sensing station. The repeated side-to-side belt motions ("excursions") cause flattening and wear of belt coatings under edge dams, and this uneven wear of belt coatings in turn leads to less uniform heat transfer in the belt while in the moving mold. Such mechanically induced distortions in turn adversely affect the quality of the product being cast. The present invention provides a steering method and system responsive to a single signal source, fixed on a belt edge. This single signal source can be achieved by notching or otherwise cueing a belt at one place along an edge so that the steering sensor senses this cue notch as the belt is revolving. A first electrical circuit is arranged to sense this cue notch and to activate or initiate, i.e. to cue the commencement of, a sensing control operation. The result of the latter control operation, in response to sensing of the tracking error of a predetermined control place or region on the belt following the "cue", then governs the steering mechanism and thereby eliminates or substantially reduces the prior-art continual "hunting" steering problems in twin-­belt metal casting machines.

Abstract: There is disclosed a BCH code decoder for correcting a natural number N of error bits occurring in a code sequence composed of bits encoded by a BCH encoding method, and a method therefor. In the BCH code decoder and the BCH decoding method, first to N-th syndromes are generated from an inputted code sequence encoded by the BCH encoding method, respectively, and first to N-th check codes are generated by subtracting predetermined syndromes to be calculated when an error occurs at a predetermined bit of said code sequence from said first to N-th syndromes, respectively. Thereafter, error correction information is generated when a number of error bits represented by said first to N-th syndromes is equal to the sum of one and a number of error bits represented by said first to N-th check codes, and one or more error bits of said inputted code sequence are corrected according to said error correction information, thereby outputting the decoded code sequence.
