Title: Hydroforming process obviating long-stroke, expensive machinery
Inventor: SIEGERT KLAUS PROF DR ING
IPC: B21D26/02
Filed: 1996-08-22
Abstract: In the hydroforming tubular blanks (W), which is economical in machinery and highly-productive, the main press frame has a piston-cylinder closure system (5) acting on a moulding tool with two or more die halves (2, 3), in which high internal pressure will be applied to the tubular blank.

Inventor: LOTH-KRAUSSER HARTMUT
IPC: H02J1/14
Filed: 1996-09-14
Abstract: The invention concerns a method and arrangement for disconnecting consumers who are connected to a voltage source, specially a direct voltage source. For the purposes of the present invention direct voltage systems are, for instance, the well-known mobile equipment driven by solar cells, primary or secondary batteries. The present invention is based on the knowledge that several consumers are often present in a voltage system, apart of which can be disconnected immediately when one or several conditions for disconnection are fulfilled, while another part of the consumers should be gradually disconnected due to technical safety reasons or psychological aspects. According to the invention consumers connected to a voltage source can be disconnected in two steps, that is, the power passing through the consumers is reduced, for which a slow regulation is offered, and later the power passing through the rest of the users is disconnected. The invention also concerns a circuitry to carry out the invented method, which has a controllable resistance element (M2) to disconnect at least one first consumer (V) and a controllable connecting element (M1) to disconnect at least one further consumer (V1), which are controlled by a regulating circuit. The regulating circuit is designed in such a way that it is only after the power is flowing through the first consumer (V) that the power of the other consumer (V1) can be disconnected.

Title: Low temperature production method by mixture Joule-Thomson process
Inventor: ALEXEEV ALEXANDER DIPL ING
IPC: F25B31/00
Filed: 1996-11-26
Abstract: The method generates low refrigeration and freezing temperatures by an oil lubricated compressor from which the liquid part of the refrigerant and oil mixture is separated out from the high pressure flow and used to pre-cool the gas part by use of a throttle valve. The compressor (1) passes high pressure gas and oil mixture through a post-cooler (2) into an oil separator (6). The gas part passes to an adsorber (7) to reduce the flow to fine droplets and a pre-cooler (8). The liquid part also passes through the pre-cooler via a throttle valve (9) back to the compressor. The gas part is also throttled by valve (4) after passing through heat exchanger (3) and evaporator (5), after which it is passed through the heat exchanger at a lower temperature back to the compressor.

Title: Leak monitor for pipeline for gas or liquid
IPC: F17D5/04
Filed: 1997-05-28
Abstract: The leak monitoring strip has a conductor (21) made of a material which changes its conductivity when exposed to the particular fluid from inside the pipeline.  The conductor is applied to the back of a self adhesive strip (22), which is stuck to the pipe and covered by a porous layer (23), to soak up any leaks.

Title: Reamer for cylindrical bore
Inventor: ENDE WOLFGANG DIPL ING
IPC: B23D77/00
Filed: 1997-07-16
Abstract: The reamer forms a bore for a fitted bolt, particularly in work of aluminium alloy, the rotary tool being fed forward for a set stroke and then returned to the starting position. A gas, vapour or initially liquid cleaning agent is delivered under pressure into the work, emerging into the swarf-chambers of the tool near the latter's tip, so that the fine dust formed is extracted from the bore in the rearwards direction. Spiral cutters (3) extend along the reamer (1), which has to the rear of its cylindrical guide pin (4) a cone friction surface (5) with an angle of less than 10 degrees and of a predetermined length. The cutters extending for this length have a negative rake. The length of the cone surface can be approximately 5 mm and its angle approximately 2 degrees. The negative rake can be roughly 45 degrees, and it can extend for between 0.01 and 0.05 mm.
Patent DE-19733327-A1 (DE)
Title: Printer for printing endless sheet medium
Inventor: KIKUCHI SHINJI
IPC: B41J11/42
Filed: 1997-08-01
Abstract: The printer (1) conveys a recording carrier (P) in a first direction using a tractor unit (6) in an endless printing operation. The tractor unit conveys the carrier in a first and second direction. A control unit determines whether the leading edge sensor (5) has detected the leading edge in due order. The printer begins the conveying back of the carrier (P) in the second direction, if a transition is arranged between two sheets of the recording carrier (P) at a specified position (STOP). So the leading edge sensor (5) will detect the leading edge during the return conveying, the control unit compares a first value, corresponding to the amount which the recording carrier (P) is conveyed, since the beginning of the return conveying until the detection of the leading edge, with a second value. The second value corresponds to the distance of the leading edge sensor (5) from the specified position (STOP).
