Title: Cleaning tube for sewage disposal system - has cover with non return valve and cover locking system
Inventor: KESSEL BERNHARD
IPC: E03F3/04
Filed: 1975-12-24
Abstract: The cleaning tube is for sewage disposal systems on an externally accessible link between a waste collector and its draining outlet for cleaning purposes. The cleaning tube has a normally closed cover and it prevents back flow of sewage and acts as seal against sewage gases. The non return valve within tube prevents effectively any back flow of sewage. The cleaning tube (1) top has an inserted length of tube (16) with an automatically acting non return valve (20) locked into a cleaning tube cover (9) by an external actuated toggle lever (13) and locking cam (14). The locking system is operated if there exists a long term back flow danger, even if the non return flow valve acts as a protector.

Title: Regenerative rotary heat exchanger for fluids - has locks and leakage gas control system responding to sample purity
Inventor: SCHLUETER SIEGFRIED HANS-DIETM
IPC: F28D19/04
Filed: 1976-08-02
Abstract: The regenerative heat exchanger is used for liquids and gases. The cylindrical regenerator chamber is filled with heat storing material and the supply and removal pipes of fluids rotate relative to each other. The lock chambers (6) within connection channels (2, 3) are enclosed by circumferential seals and have suction chambers. The gap losses of radial seals are removed by suction. The lock gases and sealing gap leakage gases are drawn away in controlled manner. The min. sucked gas quantity is achieved by the measurement of the purity of a sample of sucked gas. The transfer of toxic substances from crude gas into pure gas is completely prevented. The heat exchanger can hence be used for fluids otherwise used only in perfectly sealed systems.

Title: Auto-thermal coal gasification - by plunger pumps passing fuel portions to mixing head with gasifying agent
Inventor: LANGHOFF JOSEF DIPL CHEM DR
IPC: C10J3/54
Filed: 1977-01-05
Abstract: The autothermal gasification of granular fuel, e.g. bituminous coal with oxygen or air and steam or carbon dioxide, uses a mixing head into which the fuel is pumped in portions by several (three) plunger pumps acting against intermittently-operated plug valves. In the mixing head the fuel is mixed with the gasifying agent before being passed through a burner into the gasifier. The process simplifies the conventional fuel charging procedure and enables the gasification to be carried out at higher pressure (200 bar). The throughput is increased and the gas produced is of higher quality.

Title: Digitally controlled acceleration and deceleration system - generates demand from summed acceleration and speed demands for machine tools
Inventor: ONODA FUMIO
IPC: G05B19/416
Filed: 1978-03-13
Abstract: A digitally controlled accelerating and retarding system for machine tools, automatic curve tracing, magnetic disc drives, etc. is designed to achieve acceleration or retardation to a defined speed in a shorter time and with less energy consumption than with current systems. The position and speed of the controlled object are measured and the movement controlled using a relation between desired position, actual position, and actual speed. In acceleration mode a demand for constant acceleration and a demand for constant speed in the same direction are calculated and summed to produce the demand signal. In deceleration mode the constant acceleration and speed demands are of opposite sign and similarly summed.

Title: Line transmission characteristics analysis - using Fourier processor and quotient of corresp. amplitudes for transmitted and received frequency to obtain line resistance
Inventor: BLAESS GERHARD DIPL ING
IPC: G01R27/28
Filed: 1978-12-06
Abstract: The analysis system uses a series of test pulses of defined amplitude and phase and a Fourier processor to provide the amplitude and phase of the harmonics and individual frequency components of the received pulses. The Fourier processor provides at least one complex amplitude value (Ax) originating from a specific frequency tx within the transmitted test pulses. This amplitude value (Ax) is divided by the amplitude (Ax) of the corresp. transmitted frequency, to obtain a quotient which is multiplied by a correction factor to provide the resistance of the measured line. Pref. a corresp. quotient is obtained for each harmonic of the test pulse, so that the frequency-dependence of the line resistance can be determined, each of the measured resistance values supplied to a storage and display device (ARE).
