Patent DE-3220419-A1 (DE)
Title: Method for converting a physical quantity, and angle measurement converter for carrying out the method
Inventor: KELLER HANS
IPC: G01D5/24
Filed: 1982-05-29
Abstract: A method for converting a physical quantity (angle, distance) into a proportional output direct current and an angle measurement converter for carrying out the method are proposed in which, in accordance with the principle of a charge amplifier, a measuring capacitor arranged at the input of the amplifier is fed with a squarewave voltage, the amplifier output voltage being simultaneously rectified in such a manner that the switch-on period of a switch forwarding this output signal, for example to a buffer memory, is both shorter than the pulse duration of the feed and squarewave signal and also maintains a predetermined distance from the front and rear edge of this signal. As a result, delays in the charge amplifier and in the switches remain without influence on the output voltage.
Patent DE-3222548-A1 (DE)
Title: Liquid flow controller
Inventor: NOLTE HEINZ
IPC: G05D7/01
Filed: 1982-06-16
Abstract: The invention relates to a liquid flow controller in which, depending on the pressure prevailing in the liquid, an elastic ring works against a profiled core and carries out the control by varying the flow cross-section. In the event of sharply fluctuating pressures on the inflow side, it is possible in such controllers for it to happen that the pressure on the outflow side is briefly higher than on the inflow side, and that a return flow consequently arises through the controller. The liquid flow controller according to the invention is configured such that it prevents such a return flow. It has for this purpose an additional rotary part which closes the liquid line in the event of a return flow. <IMAGE>

Title: Process for the production of a porosity in components or workpieces made of a metal or an alloy
Inventor: KUSAEV JURIJ I
IPC: C22F1/02
Filed: 1982-07-14
Abstract: The process comprises subjecting a component or workpiece made of a metal or an alloy to a heat treatment in two stages. The heat treatment is first carried out in the presence of a gaseous oxidising agent at a temperature of 0.3-1 of the melting point of the starting metal or the starting alloy with formation of a compact oxidation product at a degree of oxidation of 100%. The compact oxidation product obtained is given a heat treatment in the presence of a gaseous reducing agent with reduction of the metal from the compact oxidation product. The heat treatment mentioned in the presence of the gaseous reducing agent is carried out at a temperature of 0.2-1 of the melting point of the reduced metal or of the reduced alloy.
Patent DE-3226494-A1 (DE)
Title: Method for testing an electrical circuit board
Inventor: LINDNER ADALBERT
IPC: G01R1/073
Filed: 1982-07-15
Abstract: The circuit board (1) is pulled in a familiar manner against probe pins (4) of a vacuum adapter by means of low pressure. Before the electrical test starts, the extraction is interrupted for a short time and, at the same time, compressed air is blown in impulses into the evacuated space. This raises the circuit board (1) from the probe pins (4) and abruptly presses it down again. This allows interfering cover layers on the contact points to be reliably penetrated by the probe pins, which considerably improves the contacting. <IMAGE>

Title: Device for heat transfer
Inventor: HEZEL WERNER DIPL ING
IPC: F28F27/00
Filed: 1982-08-31
Abstract: The application relates to a device for heat transfer between a liquid and a gaseous heat carrier. Such a device can be used for heating the air current guided into the cabin interior of a motor vehicle. The quantity of heat to be transferred is determined by controlling the flow rate of the liquid heat carrier conveyed by a pump (17) through a heat exchanger (1) consisting of a plurality of branch circuits (2) extending in parallel. In order to render the quantity of heat to be transferred independent of changing pump speeds, the branch circuits (2) for the liquid heat carrier (3) can be switched individually and essentially in pure open/closed operation.

Title: Circuit arrangement for generating the high tension for television reproduction tubes
Inventor: HEISTER HEINZ
IPC: H04N3/185
Filed: 1982-09-29
Abstract: It is known to obtain the high tension for television reproduction tubes from line retrace pulses by means of a high-tension rectifier cascade. As the line frequency increases, the power dissipation in the rectifier cascade also increases so that the commercially available cascades cannot be used for display devices with a high number of lines. According to the present invention, a resonant transformer (TR) is provided which is tuned to approximately the line frequency, in the primary circuit of which an electronic switch (TS1) controlled with line-frequency pulses is located and to the secondary winding of which the high-tension cascade (KS) is connected. Main field of application of the invention are high-resolution television display devices. <IMAGE>

Title: Circuit for switching on and off a railway crossing safety system
Inventor: HILTNER FRITZ
IPC: B61L29/08
Filed: 1982-10-15
Abstract: In railway systems with radio-controlled railway crossing safety systems, it is to be ensured in the event that a plurality of shunting engines have simultaneous access to the railway crossing safety system that said system is switched off in each case by that engine which has also caused the system to be switched on. On the other hand, it is also to be ensured that this switch-off request can only succeed if no other engine has in the meantime itself caused the railway crossing safety system to be switched on. This request is realised by means of a relay circuit in which each engine acts on separate switch-on and switch-off relays which switch a common switch-on relay or a common switch-off relay (A) for the railway crossing safety system via OR switching operations. The switch-on relays act on associated storage relays (S1,S2,S3) which store the switch-on requests until the associated switch-off relays switch. Contacts (S1/3, S2/3, S3/3) of these storage relays in the switch-off circuit of the common switch-off relay (A) prevent the railway crossing safety system from being switched off as long as a switch-on request is still in existence. <IMAGE>

Patent DE-3306577-A1 (DE)
Title: Device for forming twist selvedges for double-pile fabrics
Inventor: WELZEL GUENTER
IPC: D03C7/06
Filed: 1983-02-25
Abstract: The invention relates to a device for forming twist selvedges for double-pile fabrics, which loops the twist threads around the vertical threads of the upper and lower shed as a half twist and which ties in the twist threads by means of weft threads, the twist needles being guided between the marginal warp threads and rake-like vertical-thread grids being shifted alternately to the left and right in relation to the twist threads. This device can be used for double-pile carpet looms. In comparison with known devices of this type, it has been designed extremely simply and its mode of operation has been improved. It becomes possible to produce a plurality of twist selvedges next to one another directly adjacent to the fabric selvedge, and it can be used as a catch strip, with only one twist-selvedge device for the strips lying respectively one above the other at the two fabric selvedges of the double-pile fabric. This is achieved in that two slides equipped with twist needles for the upper and lower shed are movable simultaneously and oppositely to one another, and the needle frame is arranged in a stationary manner and has grid bars extending through the two sheds, whilst the vertical-thread grid is a component of a double rocker and is laterally movable.

Title: Apparatus for determining the thermal conductivity of a solid material
Inventor: RAPP WILHELM
IPC: G01N25/18
Filed: 1983-05-13
Abstract: The sample 1 is heated by means of a laser flash and the change in temperature at the surface of the sample 1 facing the differential temperature pyrometer 6 is measured. An optimum temperature resolution in a temperature range from 20 to 3000 DEG C is achieved by using three detectors 8, 9, 10 comprising different detector materials. To screen the pyrometer 6 from the laser flash, a second camera shutter 11 closes the beam path to the pyrometer 6 for 2 ms. A first camera shutter 7, which is inverted with respect to the second camera shutter 11, simultaneously opens the beam path from the laser apparatus to the sample 1 and then keeps any stray light from the sample 1 out of the laser apparatus 4. Advantages are the wide temperature range from 20 to 3000 DEG C accompanied by high temperature sensitivity, the short dead time prior to the start of the measurement, the fact that the measuring signal is free of radiation components from the laser apparatus 4, and the fact that the pyrometer 6 does not require screening from the stray laser light. <IMAGE>

Patent DE-3406013-A1 (DE)
Title: Levitation train
IPC: B60V3/04
Filed: 1984-02-20
Abstract: In future, trains will hover over the rails. This would be possible if the holders shown below were attached to the rail heads. The counter holder fits the said holders like the lid on a pot which permits excess pressure to be produced in the pot. Thus, the air cushion is built up between the holders on the respective rail head and the counter holder on the train by forcing in air. Nonetheless, the play between the holders on the rails is so large that the edges of conventional wheels can also be accommodated there. The air cushions are produced by sucking air out of the direction of travel, as a result of which the train is simultaneously sucked forwards; for the purpose of braking, sucking takes place from the opposite direction. However, the actual drive is effected by means of car tyres on the rails and electric drive motors of the locomotive; here, the weight of the locomotive rests on the air cushion. Suction cups according to P 3400827.6 suck tight onto the rails for the purpose of emergency braking. Electrical internal-rotor motors can serve as suction motors, the axis of which motors is a threaded tube and causes it to rotate in such a way that the air column located in it must move forwards in the manner of a screw so that suction or increased air pressure is produced. In the case of the suction cups failing, the counter holders of the train grind on the conventional rail head. <IMAGE>

IPC: G01B17/02
Filed: 1984-03-24
Abstract: It is the object of the invention to develop a device by means of which the test head of an ultrasonic device can be applied inside metallic hollow bodies at measuring sites which are difficult of access by using two methods (toggle lever method and permanent magnet method) in such a way that the measurement of the thickness of the residual wall and testing of welds can be carried out without the expenditure of high costs. This holds, in particular, for measurements in curved metallic hollow bodies whose measurement sites can be reached only by means of a bendable arm. The contact pressure on the ultrasonic test head that is required for the measurement is achieved using the toggle lever method or permanent magnet method. <IMAGE>
