Title: Holding brake for railway units
Inventor: SCHMALL JUERGEN DIPL ING
IPC: B61K7/12
Filed: 1984-07-27
Abstract: Trains held by holding brakes must be extended before the brakes are opened because only in this way can it be established whether all vehicles are coupled to one another and to a locomotive driven up to the uphill end of the train in question. In order on the one hand to safeguard the couplings of the vehicles during extension and on the other to prevent unwanted noises which have hitherto occurred when drawing vehicle wheels out from the still closed brake, the invention proposes to make the contact pressure of the brake retarder beam on the inlet end of the brake less than in the remaining brake area. This is done by using differently loaded sets of springs or by the use of sets of springs with different characteristic curves.

Patent DE-3430656-A1 (DE)
Title: Process for producing individual elements or segments for antenna fairings from polyurethane
Inventor: PATSCHKE HARTMUT
IPC: H01Q1/42
Filed: 1984-08-21
Abstract: The present invention relates to a process for producing individual elements or segments for antenna fairings from polyurethane and the antenna fairing itself. In the prior art, problems arise in the individual elements, for antenna fairings, made of PUR rigid foam as regards multiple reflection and narrow band transmittability. The invention provides a remedy by, during the PUR foam formation, controlling, as regards its thickness and bulk density, only the formation of a cover layer or edge zone which is closed towards the surface, in order to obtain the lowest possible dielectric parameters for the material. This is achieved by different temperature controls of the two outer surfaces of the mould so that the individual element in the end has only one integral cover layer or edge zone which is closed towards the surface on one side. The invention thus dispenses with the use of protective films made of other material. <IMAGE>

Title: Speed-measuring arrangement for generating speed-dependent analog signals
Inventor: WEBER ROLAND DIPL ING
IPC: G01P3/486
Filed: 1985-07-29
Abstract: The measuring arrangement generates a control variable for a speed control loop, in which arrangement a signal disc with a periphery which is like a diaphragm or comb is mounted on a shaft whose speed is to be determined, and which has transducers spatially offset by 180 DEG , in the form of light barriers which each generate sinusoidal voltages that are mutually offset by 90 DEG  and are converted into square wave signals with the aid of summing amplifiers and averaged, and from which the actual speed value for a speed governor is formed with the aid of frequency-to-voltage converters. Arranged between the transducers (7, 8) and the summing amplifiers (13, 14) for the purpose of keeping constant the signal amplitudes of the sinusoidal voltages obtained from the transducers are amplitude controllers (11, 12) which by squaring the AC voltages formed by the optoreceivers of the transducers (7, 8) and adding them generate an actual amplitude value, and by subtracting the latter from a desired amplitude value form a manipulative variable for keeping the actual amplitude value constant. <IMAGE>

Title: Flat-seat valve
Inventor: KROEMER GUENTER DIPL ING
IPC: F02M69/50
Filed: 1985-09-12
Abstract: A flat-seat valve for a continuously functioning fuel injection system has a casing 1, 2, the interior of which is divided by a diaphragm 3 into two chambers 4, 5, of which the first chamber 4 is connected to a fuel metering valve and has a valve seat 8, from which a duct 7, connected to an injection nozzle, emerges. In the first chamber 4 a spring 9 is also provided, which endeavours to push the diaphragm 3 away from the valve seat 8. The second chamber 5 is connected to the fuel pump. In order to damp oscillations of the diaphragm 3, a closed, gas-filled elastic hollow body 13 is arranged in the second chamber 5, which body in the event of oscillations of the diaphragm 3 is compressed, causing a rapid subsidence of the oscillations. Alternatively, a plate may be provided in the chamber 5 parallel to the diaphragm 3 and at a small distance from the latter, so that in the event of oscillations of the diaphragm 3, the fuel present between the plate and the diaphragm must be partially displaced, which leads to a rapid subsidence of the oscillations. <IMAGE>

Title: Method of constructing a line drainage system
Inventor: ARNOLD ROLF
IPC: E02B11/00
Filed: 1986-01-27
Abstract: The invention relates to the construction of line drainage systems consisting of drain pipes and filtering envelopes. The technical object of the invention is to create a single-stage method of continuously constructing line drainage systems of high quality while increasing the working productivity and reducing the expenditure of energy while larger moving masses are avoided and to obtain a high uniform packing density of the enveloping material by interaction of casing threads. According to the invention, a filtering envelope, the overall width of which corresponds to at least the pipe circumference, is fixed to the drain pipe by the intermeshing of casing threads at mesh rows running in the longitudinal direction by means of an encasing device working with grippers. While being transported together with the drain pipe to the encasing point, the filtering envelope is laid around the drain pipe in such a way that the edges run parallel to the pipe axis. It is also possible within the scope of the invention to gradually lay further envelopes around the drain pipe before the intermeshing of the casing threads.
