Title: Process for determining the amount of leakage of a gas-air mixture from closed systems, and apparatus to perform the process
Inventor: ZAZIGIN ALEKSANDR SERGEEVIC
IPC: G01M3/38
Filed: 1982-02-09
Abstract: The apparatus for determining the amount of leakage of a gas-air mixture from closed systems effects a process for determining the amount of leakage of a gas-air mixture from closed systems, and contains a working chamber (3) connected to an apparatus (1) for withdrawing the gas-air mixture and to a vacuum pump (9). An infrared radiation source (11) is arranged with regard to an entry opening (10) of the chamber (3), while an infrared radiation receiver (14) is arranged in the path of the beam leaving the chamber (3) with the gas-air mixture, which receiver is electrically coupled to an input (16) of a comparator circuit (17). Electric valves (7 and 8 respectively) are arranged directly at the inlet and outlet of the chamber (3), and a vacuum pump (6) is arranged at the outlet of the chamber (3) to conduct the gas-air mixture, with the valve (8) closed, until the concentration of a sample gas in the gas-air mixture in the chamber (3) has become equal to its predetermined concentration in the gas-air mixture in the closed system. The time to produce equality of the concentrations, and a pressure gradient in the chamber (3) from the beginning of infeed of the gas-air mixture to a pressure reached at equality of the concentrations, are measured by a timer clock (41) and a pressure transducer (20) which are connected to a computer unit (19); the amount of leakage is determined by the computer unit (19) according to the flow quantity of the gas-air mixture from the closed system. <IMAGE>

Patent DE-3205296-A1 (DE)
Title: Frequency multiplier
Inventor: GEIGER WERNER
IPC: G06F7/68
Filed: 1982-02-15
Abstract: The frequency multiplier consists of a binary counter which counts fixed-frequency pulses for the duration of the period of an input signal. A second binary counter continuously counts pulses of a second frequency which is a multiple of the fixed frequency. When the count of the first binary counter has been reached, the second binary counter is cleared by a comparator and starts to count again from the beginning. Each clearing produces an output pulse. The ratio between input frequency and output frequency is equal to the ratio between the frequency of the pulses counted by the first binary counter and the frequency of the pulses counted by the second binary counter. To multiply the frequency of square wave signals whilst retaining the ratio between the duration of the positive part and the negative part of the input amplitude, pulses of a fixed frequency can be counted into a binary counter in each case for the duration of a positive or negative input amplitude part. To generate an output amplitude part, a chip used for switching the inputs of a comparator can connect the comparator outputs to the outputs of the binary counter used for measuring the amplitude part corresponding to the amplitude part to be generated, or to memories following this counter. The inputs of the comparator to be compared therewith are connected to the outputs of a secondary binary counter which counts pulses of a frequency which is different from the frequency used for measuring the amplitude parts. The output pulses of the comparator or of an AND gate, the inputs of which are preceded by invertors which, in turn, are connected to the outputs of the second binary counter, are divided by two in order to obtain the output signal of the frequency multiplier.

Title: Drive unit for producing kinetic energy by utilising the expansion of noncombustible gases
Inventor: PICKEL NORBERT
IPC: F01K25/10
Filed: 1982-02-23
Abstract: The patent application relates to a novel drive unit which operates on the principle of the heat pump. In contrast to conventional heat pumps, the gas CO2, which is compressed in a compressor driven by an internal combustion engine, is used as the drive medium for the transmission device (engine) itself. The gas CO2 makes it possible to employ pressures of approximately 100 bar, with the result that the dimensions of the drive motor itself can be small. A phase change from the gaseous to the liquid phase is not absolutely necessary in the case of the gas CO2. The power of the internal combustion engine for driving the compressor is only of the order of magnitude of 25 % of conventional internal combustion engines in automobiles for the same output power. The consumption of petrol or diesel is therefore also only of the order of magnitude of 25 % compared with conventional engineering.

Title: Motor pump unit
Inventor: WUNDERLICH ERHARD DR ING
IPC: F04C15/00
Filed: 1982-10-13
Abstract: In the case of a motor pump unit comprising an electric motor and a pump for delivering liquids, preferably liquids serving for obtaining or conveying energy, the problem exists of using the power losses occurring in electric motor and pump to heat the conveyed liquid in order to positively influence the overall energy balance of the system into which the motor pump unit is built, for example an oil heating system or even an absorption heat pump system. To solve this problem it is proposed that the electric motor and the pump be installed in a closed pot, that the electric motor be wet- running with bare windings and the inside of the pot be a part of the flow path of the liquid delivered by the pump. In addition to other characteristics the electric motor and the pump are preferably arranged perpendicular with the intake mouth uppermost and the entire unit is preferably coated with a thermally insulating layer.

Title: Printing unit guide for typewriters or similar machines with a carriage
Inventor: SPANNEHL HANS-PETER ING GRAD
IPC: B41J25/304
Filed: 1983-03-05
Abstract: The requirements for ever increasing typing speeds also entail a corresponding design of the printing unit guide. The intention of this printing unit guide is, on the one hand, to guarantee a parallel smooth run of the carriage along the recording medium and, on the other hand, to allow easy assembly and simple exchange. The invention is based on the object of providing a printing unit guide which can be assembled and dismantled easily and conveniently, and in which there is no difficulty with the parallelism of the guide rails. This object is achieved in that at least one guide rail (35, 45) has a cylindrical shape, about which the carriage (1) is pivotably arranged. The invention allows precise guiding of the printing unit in the immediate vicinity of the daisywheel, the guide rollers (23, 25) which interact with a guide rail (35, 45) simultaneously taking on the function of the swivel bearing for exchanging the daisywheel. This enables a low number of parts to be used for the printing unit guide, as a result of which there is no slack in the pivots. <IMAGE>

Inventor: VONDERECK HERRMANN
IPC: B05C19/06
Filed: 1983-03-24
Abstract: The adhesive feed device has a heatable adhesive reservoir (7) which has a receiving chamber (8) for a predetermined volume of adhesive and is preceded by a heatable screw conveyor (2) receiving adhesive granules and an adjoining heatable adhesive duct (6) connected to the receiving chamber (8), and which is equipped with a pump (10) which pushes the adhesive out of the receiving chamber (8) via a feed duct (12,13,14) to the application apparatus (1), and also with a return duct (17,18) opening into the receiving chamber (8) for the unused adhesive coming from the application apparatus (1). An adhesive feed process is carried out with this feed device in which the adhesive granules are brought into a conveyor path and then preheated during transport, and the adhesive then flows through a heating path in which it is brought to its processing temperature and is liquefied, and then enters a heated adhesive reservoir, from which it is fed under pressure to the application apparatus and into which the adhesive not used in the application apparatus flows back. This feed device works with the application apparatus in the adhesive and heating medium circuits, and always brings only a given adhesive volume into the processing state, so that fresh adhesive is always ready for use. <IMAGE>
