Title: Laser interferometer for surface investigation - has beam splitter, mirror and detector element built into basic unit, with one element movable w.r.t. unit and has fibre=optic coupling
Inventor: HEIMBECK HANS-JOERG DR
IPC: G01B9/02
Filed: 1992-02-19
Abstract: The laser interferometer contains a beam divider dividing the light from a laser light source into two paths.  One beam is directed as a reference beam onto a mirror element, the other to the surface under investigation as a measurement beam.  After reflection the beams interfere and the interference pattern is detected. The divider (2), mirror (3) element and detector element (5) are combined in a mechanical base unit.  The beam from the laser source, which is mounted separately from the base element. is coupled into it via an optical fibre. USE/ADVANTAGE - For investigating surfaces, esp. manufactured surfaces of optical quality.  At least main part of interferometer is small and light.

Patent DE-4208194-A1 (DE)
Inventor: ABELEN THOMAS
IPC: F04C29/02
Filed: 1992-03-14
Abstract: The invention concerns a method of operating an oil-sealed vacuum pump (1) with an outlet nozzle (8) provided with a flap valve (9), an oil feed duct (11) which has a valve (13) and has its outlet in the suction chamber of the pump, an electric drive motor (14) for the rotor (4) with coils (15 and 20), and a capacitor (16). The valve (13) in the oil feed duct (11) is closed when the pump (1) is switched off or in the event of a power cut. To ensure that a vacuum is maintained even when a mechanical fault occurs, it is proposed that the valve (13) in the oil feed duct (11) should be controlled by the rotational speed of the rotor (4) and drive motor (14) so as to remain open at normal operating speed and to close when speed is reduced; the auxiliary coil (20) of the motor can serve as a sensor.
Patent DE-4208208-A1 (DE)
Inventor: GRUETZMACHER KLAUS DIPL ING
IPC: B21B9/00
Filed: 1992-03-14
Abstract: The invention concerns a process for reducing scale formation during hot forming of metal, in particular steel. The metal, which is formed in its heated state and under brief high pressure, the deformation being substantially plastic, is subjected during a subsequent stress-relief phase, during which the degree of plastic deformation is reduced, to treatment with an inert gas such as nitrogen. In a device for carrying out the process, a device for supplying inert gas is connected to the device used for hot forming the metal; the former has a large number of jets directed towards the formed metal as well as a system for restricting the supply of inert gas, after the metal has been formed, to the stress-relief phase. In the hot-rolling of steel, for example, inert gas jets are arranged at the output end of a roll stand in such a way that the inert gas is blown obliquely against the direction of feed of the steel into the space created around the formed metal between the output end sections of the last roll housing and the open espaces of the roll gap at the sides of the formed metal. An inert gas pressure higher than the atmospheric pressure thus builds up in the said space.

Title: Assymetric wound synthetic yarn bobbin - is wound with faster reciprocating guide movement in one direction than the other
Inventor: SCHIPPERS HEINZ DIPL ING DR IN
IPC: B65H49/02
Filed: 1993-04-22
Abstract: To wind a synthetic yarn on to a bobbin, a reciprocating movement is given to the yarn at a lower speed in one direction than in the other. At the start of winding, the yarn is wound round the bobbin sleeve as a reserve, outside the reciprocating path zone. The yarn reserve is on the side of the bobbin where the yarn is moved at a slower reciprocating speed. Also claimed is a method to take off a synthetic yarn, over the head of the bobbin, where the yarn is taken from the side of the bobbin where the yarn has been wound at a higher reciprocating speed. Pref. in the reciprocating guide action, the synthetic yarn is moved towards the yarn reserve at a lower speed than in the opposite direction. USE/ADVANTAGE - For the assymetrical winding of a bobbin with synthetic yarn material. The operation reduces the risk of yarn breakage when winding and taking-off over the top of the bobbin with a high speed take-off.
