Patent DE-3007288-A1 (DE)
Title: Large hot gas pipe stop valve - has sealing rings actuated by sets of bellows connected in parallel
Inventor: MUELLER RUDOLF
IPC: F16K5/20
Filed: 1980-02-27
Abstract: The stop valve is for large-dia. pipes handling gas at high temp. and pressure having a spherical rotary plug, against which sealing rings are thrust axially by pressure-operated bellows. The rings have two or more sets of evenly-spaced bellows round their periphery and connected in parallel. Each group of bellows has its own pressure circuit, with pressure gauge connected to a regulator, the latter varying the pressure dependent on the discrepancy between the acutal and desired values. The regulators are connected to a control unit which, after flow has taken place for a set period in one group, automatically alters the desired value of the operating pressure in the other group.

Title: Video tape recorder tape application mechanism - has electromagnet actuated by playback or recording keys, which operates sliding rod with connected friction wheel
IPC: G11B15/665
Filed: 1980-05-13
Abstract: The video tape recorder includes an electromagnet in the mechanism which can be switched by actuation of the playback or recording key and moves a sliding rod in the actuation direction. To this rod is connected, via a spring a friction wheel- driving a tape drive wheel for the winding reel. The playback or recording keys also provide the switching of a drive mechanism, pulling out a video tape from a cassette, using a pressure roll. The mechanism is also used for looping the tape round a rotary head and to clamp it between itself and a tape drive shaft for the tape transport. The mechanism is actuatable by a stop key for reversing the pressure roll towards the cassette for tape unwinding. The mechanism contains a swivel lever plate for switching to the unwind state, as well as a swivel lever to prevent the sliding rod to return in its rest position in cooperation with a pin on the swivel lever plate, when the stop key has been actuated.

Title: Compensator for distortion in transmission of PCM signals - compensates for propagation time and word limit and loss of synchronism signal by switching
Inventor: SZIGETI TIBOR DIPL ING
IPC: H04J3/06
Filed: 1980-09-29
Abstract: The application is to PCM signal transmission in which individual words of different messages are interleaved. The proposed circuit counteracts time distortions which can be introduced into a transmission due to variations in the transmission line characteristics. The compensator comprises three stages. In the first (3) the incoming signal (ILN) is corrected for propagation time errors using a first in-first out logic (1,2). The time corrected signal is then operated upon by a word boundary compensator (4) which corrects the time length with reference to the multiplexing frame. Finally a synchronising unit (5) interrupts the signal current if synchronism of the input signal is lost. The equipment operates on 8-bit words and is used on the first three levels of the digital hierarchy.

Title: Method for the production of shell moulds and cores for casting metals and other materials capable of flow
Inventor: REGITZ KLAUS
IPC: B22C9/02
Filed: 1981-02-26
Abstract: The shell moulds are produced from organic non heat-resistant, binder-free moulding materials such as, for example, cotton or paper, which are moistened with water or some other freezable liquid and then frozen to give a sturdy mould shell. Freezing is preferably accomplished by means of liquid nitrogen although other chemically inert supercooled gases, liquids or solids are possible. After the metal has flowed into the mould, a sufficiently thick boundary layer solidifies before the mould loses its strength due to the heat of the metal. In the process, the liquid used for freezing the mould is melted and evaporates and the moulding material is possibly destroyed. The shell mould (2) which forms the mould cavity (3) is held by a supporting frame (1). <IMAGE>

Title: Method for automatic adjustment of the scanning track in magnetic video tape devices with helical track recording
Inventor: LANDECK HUBERT DIPL ING
IPC: G11B5/592
Filed: 1981-12-02
Abstract: In a method for the automatic adjustment of the scanning track for magnetic video tape devices with helical track recording with a replay speed which can be changed step by step by the recording speed, the two magnetic heads, which are arranged offset by 180 DEG on the head wheel, are preset in their position by means of piezoelectric crystal actuators in accordance with the theoretical scanning variation at the respective replay speed (skew input). To avoid the noise zones in the picture given during the transition from one nominal speed to the other, each magnetic head is spatially offset by the actuators in proportion to the function of the change in speed from one nominal speed to the other by a skew input and a relative track offset compared with the last scanned track by inputting a corresponding control voltage before the beginning of scanning.
