Abstract: The invention relates to a pressure-resistant sealing device for the opening of a hollow body, preferably a cable protection tube having a cylindrical sealing part which can be inserted into the tube opening and consists of elastic material. This sealing part has at least one through-opening and a section, running up to this through-opening, for the insertion and holding of a cable. Arranged on the two end sides of the sealing part are pressure plates which, via compression elements, press the sealing part outwards towards the inner wall of the tube and inwards towards the surface of the cable. The invention is seen in that the sealing part consists of a number of inner compression rings which can be plugged into one another and are mutually supported. These inner compression rings are arranged on both sides of a sealing element on the cable. The inner compression rings are in each case surrounded by an outer clamping ring, these clamping rings for their part consisting of in each case two clamping ring halves having through-openings for attachment elements.

Abstract: A burst mode digital data receiver automatically adjusts its logic reference voltage to be equal to one-half of the sum of the minimum and maximum excursions of a received data signal. The receiver includes a differential amplifier circuit which has a first input for receiving the data signal and a second input connected to a voltage reference circuit. The voltage reference circuit is responsive to an output signal from the amplifier circuit to produce the required logic reference voltage at the second input to the amplifier circuit by generating a feedback signal which causes the amplifier circuit to have a first gain value during the absence of the data signal and while the data signal is less than its peak amplitude and a second gain value approximately twice the first gain value for a predetermined time after the peak amplitude of the data signal is reached.

Abstract: A method for transmitting commands from an originating program to a receiving program uses the data area (26) of instructions. A first set of commands are predefined for use in the command area (24) of the instructions. A second set of commands, excluded from the first set of commands, can pass through operating system modules (18), including driver software (16), by inserting them in the data area (26) of an instruction. The second set of commands are identified by including identification codes in the data area (26), such as a predefined random number key. In addition, the command area (24) can be used to eliminate the majority of normal commands quickly by always using a specific address and command in the first set of commands to transmit the second set of commands.

Abstract: An improved clutch control system in a continuously variable transmission driven vehicle monitors driver selection of forward or reverse and implements the specific parameters for each. The control logic provides a preselected time interval for sensing of a pressure drop associated with the transition from one operating mode to another, such as from neutral to forward. The system provides for sensing that pressure drop and providing a desired fluid flow rate for clutch actuation consistent with the desired performance. The system also monitors pressure in the fluid actuation system at the end of the predetermined interval to ascertain when the pressure reaches a desired higher level indicative of a control characteristic to provide desired vehicle response to driver demand. Fluid flow to the clutch is controlled at a corresponding rate to provide a desired operating characteristic and to facilitate transition into a subsequent vehicle operating mode. Length of time frame for the associated timer depends upon characteristics of specific engines. The timer times out in a time normally required for reaching the desired, second pressure level to allow transition to subsequent operating mode.

Abstract: A control to control the acceleration mode for a gas turbine engine so as to allow the engine to accelerate rapidly with adequate stall margin by simulating a compres­sor stall limit. The stall limit is attained by generating a limiting ratio of burner pressure and another engine pressure as a function of corrected compressor rotor speed assuming that the stall margin is independent of compres­sor bleed, power extraction and degradation of engine effi­ciency. Control logic means to compensate for fan bypass duct pressure losses in a system that controls the accele­ration mode for a twin spool gas turbine engine so as to allow the engine to accelerate rapidly with adequate stall margin by simulating a compressor stall limit. The stall limit is attained by generating a limiting ratio of bur­ner pressure and another engine pressure as a function of corrected compressor rotor speed assuming that the stall margin is independent of compressor bleed, power extraction and degradation of engine efficiency. Compensation is by generating an engine pressure ratio signal as a function of corrected low pressure compressor rotor speed and using the difference between the signal and actual engine pressure ratio for modifying the simulated compressor stall limit.

Abstract: A method and apparatus for manufacturing electrodes for capacitors having a plurality of thin metal coatings on a ceramic dielectric substrate, with the coated substrates assembled in a mononlithic structure. A layer of green ceramic material (10) is formed on a support tape. This green ceramic tape (10) is moved in registration with a stencil web (20) overlying the tape. The stencil web has openings corresponding to the configuration of the conductive coating to be formed on the tape. The sandwich of tape and web is moved through a sputtering chamber (28) in which a selected metal or alloy is sputtered from a target (30) so as to fall on the stencil web (20), coating the ceramic tape wherever openings are present. The sputtering chamber is arranged so that initially the ceramic tape receives a light, low energy metal coating before being exposed to maximum sputtering. This allows a reflective coating to be formed to reflect thermal energy before the intensity of the thermal radiation reaches a level that would damage an uncoated ceramic. The coated ceramic substrate tape may then be divided and assembled into multi-layer monolithic capacitors. In a related embodiment, the metallic electrodes may be sputtered onto a plastic carrier film to form a transferable layer or decalcomania, with the electrodes later transferred to the surface of the ceramic substrate.
