Patent DE-3326286-C1 (DE)
Title: Heating device for a crystal oscillator
Inventor: HAHN HARALD DIPL-ING
IPC: H03H9/08
Filed: 1983-07-21
Granted: 1985-05-23
Abstract: A heating device with a quartz crystal is described which makes possible frequency generation in a cheap and simple manner using a quartz crystal and its heating system without limiting the accuracy. According to the invention, this is achieved by placing the quartz crystal (1) in thermal contact between two semiconductor components (2; 3) as temperature sensors or heaters. This makes it possible to use or to heat cheap types of quartz crystals, for example from the consumer sector. It is furthermore possible to heat very rapidly to the set temperature and also to compensate rapidly for interferences.   <IMAGE>

Granted: 1987-05-07
Abstract: A valve for a gas vessel has a gas-pressure line which leads to a valve chamber and which is closed by means of a closure valve disposed in the valve chamber. The valve for a gas vessel also includes a gas-takeoff line and is configured so that the valve chamber and the gas-takeoff line as well as other gas conducting spaces at the output end of the valve can be purged in the operational ready condition of the valve. The application and removal of the purging flow occurs over different paths and the purging takes place independently of the actuation of the closure valve. For this purpose, a purging line which is equipped with a purging valve is provided. The purging line opens in the valve chamber of the closure valve.

Title: Device for the testing of hollow glass containers
Inventor: ULRICH BOGATZKI HANS
IPC: G01N19/08
Filed: 1986-11-11
Granted: 1987-08-06
Abstract: The device has a sensor element (22) mounted on a rod (24) movable to and fro, by means of which it can be moved into the interior of a hollow glass container (14) into the vicinity of the bottom. The sensor element is provided underneath with a movably suspended plate (30). When the plate (30) comes into contact, inside the container, with an obstacle in the form of a glass thread (bird cage or bottom slug), it is deflected and actuates a proximity switch which emits a signal, by means of which an ejector arrangement is actuated. The device serves especially for the testing of wide-neck containers, in which defects in the form of bottom slugs are substantially more frequent than defects in the form of bird cages. <IMAGE>

Title: Weft-thread feed device for reverse-weft magazines of warp-knitting machines
IPC: D04B23/12
Filed: 1988-12-20
Granted: 1990-05-23
Abstract: A weft-thread feed device for reverse-weft magazines of warp-knitting machines possesses a bobbin creel (1), a first delivery unit (9) with a constant delivery speed, and a second delivery unit (20) with a variable thread-drive speed. The latter is proportional to the instantaneous speed of take-off of the weft threads (S) by the guide carriage (42). Located between the two delivery points (9, 20) is a storage device (14) for compensating the differences between the constant delivery speed and the variable take-off speed. It is thereby possible to deposit above all elastic weft threads on the weft-thread magazine in such a way that they have a constant tension state, in particular are tension-free or low-tension. <IMAGE>

IPC: H01R13/633
Filed: 1991-02-26
Granted: 1992-01-09
Abstract: 2.1 A known connecter makes the latching insertion of a plug into a socket possible, the latching additionally being blocked in the unplugging direction with the aid of a lock. Before unplugging, a locking sleeve on the plug must be operated by hand. 2.2 In the new connecter, the locking element (26) is connected to the end of the cable (22) which feeds the plug (20). A tension force on the cable thus releases the lock and subsequently makes it possible to unplug the plug from the socket (21). Destruction of the plug as a result of inadvertently pulling on the cable is thus prevented. 2.3 Connecters for calling systems on hospital beds. <IMAGE>
Patent DE-4116917-C1 (DE)
IPC: D21B1/32
Filed: 1991-05-24
Granted: 1992-11-19
Abstract: Known pulping (3) is preceded by a wetting stage (2) in which the dry waste paper material (1) supplied is impregnated with or in water (10 or 11) which is free of any printing ink particles of down to microscopically small, extremely fine size and free of chemicals which loosen inks, until at least the lumen of the paper fibres is filled with the pure water. This material, pretreated in this way is first subjected to pulping (3) with addition of a more or less unpurified return water (7) obtained along the paper-manufacturing process, ink-loosening chemicals being added to the return water if required. Since the fibre lumen is already filled with clean water, penetration of particles present in the return water (7) into the lumen of the fibres cannot take place during the pulping (3). In this way, a hitherto unavoidable and irreversible greying of the pulp is prevented. An installation for the manufacture of paper from waste paper material is described. <IMAGE>

Abstract: The two turbochargers are each composed of a turbine and compressor. The exhaust turbines are arranged in parallel and the compressors in series and the second or high pressure compressor arranged between the first or low pressure compressor and the engine is one size smaller than this first compressor. The high pressure compressor (2) should be at least one size smaller than the second exhaust turbine (4) coupled to it and the compressor wheel is two sizes smaller than the compressor wheel of the low pressure compressor (1). There is a bypass valve (5) pref. between compressor (2) output and the exhaust input (12) of turbine (3, 4). USE/ADVANTAGE - Design based on standard turbocharger component gives 2-stage charging for e.g. 4-stroke engines at low cost and high efficiency.
Patent DE-4218054-C1 (DE)
Inventor: LOEBIG NORBERT DR
IPC: H04L12/939
Filed: 1992-06-01
Granted: 1993-11-11
Abstract: When bit streams consisting of a number of information words are switched through in the switching networks of digital communication systems, bit corruption occurs. By correcting these bit errors, only the information word correctly switched through is forwarded to the end subscriber after the switching-through when the switching network halves are constructed in duplicate and are switched to be active in each case. The fact whether an information word has been correctly switched through is determined by means of a combined parity bit check and a bit-by-bit comparison with the information word switched through in parallel after the switching-through has taken place. It must also be ensured that bit corruption by the units (latches) involved in the switching-through process is also discovered and corrected. <IMAGE>

Title: Removal of cpds. contg. ammonia from sewage
Inventor: RENTROP MATTHIAS
IPC: C02F1/20
Filed: 1993-09-09
Granted: 1995-05-04
Abstract: To separate cpds. with an ammonia content from sewage, esp. the filtrate water from biological sludges, the solids are removed before heating in a heat exchanger and the pH value is raised to about 11 to be stripped by steam in a solid body column. The stripping steam is generated through evapn. of a part flow of the water outflow at the stripping column (10) under a vacuum. The part flow (16) is heated in a heat exchanger (14) through the hot water circuit of a sewage gas heating block power assembly. The stripping steam, loaded with ammonia, is wholly or partially condensed through heat release.
