Title: Multiple frequency digital phase locked loop
Inventor: LEVINE STEPHEN N
IPC: H03L7/099
Filed: 1990-01-12
Granted: 1991-03-05
Abstract: MULTIPLE FREQUENCY DIGITAL PLL            Abstract An improved multiple frequency digital phase-locked loop circuit is described.  The improved digital phase-locked loops utilizes a single circuit to effect both phase and frequency adjustments.  The multiple frequency digital phase-locked loop effects phase adjustments by selectively combining or subtracting a reference clock signal with a derived programmable clock signal thereby generating a composite digital phase-locked loop clock signal.  The multiple frequency provides frequency adjustments by selectively adding or subtracting pulses from the composite clock signal at a rate determined by a programmably controllable clock signal.  The improved multifrequency digital phase-locked loop is suitable for use as a tone detector with the addition of a lock detector wherein the phase-locked loop can be programmed for a plurality of known operating frequencies.

Abstract: In a heat-strengthening station (3) down-stream of a heating furnace the cooling rate of a glass sheet is retarded by means of plates (9, 11), which are set above and below a glass sheet (15) and return some of the thermal radiation back to a glass sheet and slow down convection. Thus, a glass sheet can be heat-strengthened by chilling it at a certain controlled cooling rate. In order to make also the lower plate effectively return some of the thermal radiation applied thereto, despite the rolls fitted in between, the top surface (13) of lower plate (11) is made highly reflective to thermal radiation and further corrugated in a manner that the ribs (12) of the corrugations extend between the rolls (6) close to a glass sheet.

Abstract: The apparatus accepts dry stripped crude fiber such as straw or sugar cane wastes, coconut husks, or elephant grass, compacts them into a relatively dense sheet, and bonds a strong surfacing material such as a heavy paper to the faces and edges. The sheet, continuously flowing from the apparatus, is cut into standard lengths and the cut ends are capped with the same surfacing material. A precompactor near the end of an entrance chute into the apparatus uniformly predensifies the incoming fiber prior to its compaction by means of a ram. The ram is carried on roller bearings especially adapted to withstand the weight and other forces associated with the continuous movement of the ram. The compacted material is continuously propelled by the ram and enters a press, where heat and pressure produce a dimensionally stable sheet bonded together partially by natural resins released from the fibers by the heat, and partially by mechanical interlinking between fibers. In the following operation, the sheet is covered with the surfacing material, which is successively folded over and bonded to the edges of the sheet. The surfacing material, provided in discrete rolls, is continuously available from a feeder station, which facilitates the substitution of a fresh roll as the material is consumed. In the following sawing and end sealing operations, fully surfaced sheets of standard lengths are produced.

Abstract: In a steerable vehicle with two or more axles and with at least rear axle drive, the conventional brake system consisting of service brake device and parking brake device, possibly complemented by an antiblocking system and an antislip control, is assigned an auxiliary brake device for a one-sided braking of the vehicle, the said auxiliary braking device operating in a steering angle-dependent manner. This auxiliary braking device can be actuated as required and, if a predetermined minimum steering angle of the steered wheels is undershot at a driving speed below a specific value, a one-sided braking of the wheel or wheels on the inside of the bend, at least of the driven rear axle or axles of the vehicle, is effected by selective provision of brake pressure. In this way, it is ensured that tight bends are passed through in a track-holding manner following the steering angle to the greatest extent without the vehicle being forced over to the outside of the bend. <IMAGE>

Abstract: Controlled by the central control processing unit (ZSt), which is responsible for switching operations, not only audible but also independent visual communication is provided in an exchange (VE). This can be carried out in parallel with a call which has been set up or when the terminals concerned are idle. A specific information block, selected from several possible information blocks which are stored in listed form in a memory (T), is displayed selectively at the required terminal without affecting switching system operations. The information which corresponds or is to be allocated to the selected information block is presented, for example, on the display (DL). In the case of special user configurations (e.g. Manager/Secretary systems), the permanent address allocation is predefined in the customer data store (KD) for this visual communication, i.e. wherein the actual speech path (switching device, PCM highway) is not occupied. The individual texts which are to be presented on the display (DL) via the control channel (c/d) may be selected from all the stored texts by means of, for example, a key permanently assigned to each text or through a corresponding procedure. <IMAGE>

Title: Logic valve
Inventor: YOSHINO KAZUNORI
IPC: F15B11/04
Filed: 1990-07-11
Granted: 1999-01-19
Abstract: A main poppet body of a logic valve receives inlet pressure  at  first and  second  ends.  A flow restricting orifice between the ends produces a differential pressure that maintains a pilot poppet body moveable in the main poppet body in sealing position, normally against a seat in the main poppet body, thereby preventing fluid at the second end from flowing. An external source of controllable pilot pressure acts on the pilot poppet body to permit a flow of inlet  fluid  from  the  second  end,  thereby  producing  a pressure reduction that tends to move the main poppet body out of its sealing position and consequently to permit an inlet flow past the seat of the main poppet body, to a drain. The position of the main poppet body varies in linear relationship to the pilot pressure applied to the pilot poppet body.

Granted: 1994-11-01
Abstract: The process for low-emission drying of a substance in a drum-type drying installation is suitable in particular for sewage sludge, fish meal and sludges from starch factories, soap factories and paper mills, which substances are preferably to be converted into granules.  The process is likewise very suitable for drying biomass products such as wood chips, grass, sugar beet chips and the like, since the emissions are very greatly reduced by means of this process.          The drying process is carried out in such a way that no unpleasant odours and dusts are emitted to the outside, because the actual drying circulation is closed.  Fossil fuels are used as the heat source for the burner for heating this air stream.
