Patent DE-4419038-A1 (DE)
Title: Element which generates multiple beams, and an optical printing device equipped therewith
Inventor: KATAOKA KEIJI
IPC: G02B5/18
Filed: 1994-05-31
Abstract: The present invention relates to a multiple beam generating element which generates an even number of multiple beams which have a uniform light intensity. The multiple beam generating element has a diffraction grating which is constructed from the repeated arrangement of basic phase patterns, the basic patterns being comprised of at least two types of rectangular patterns of non-uniform width and different phase height. The basic phase patterns are produced by superpositioning rectangular patterns of non-uniform width and individual phase heights in order to form a multiple layer. In an optical printing device having the diffraction grating the multiple beams which emerge from the multiple beam generating element are introduced into an acousto-optical multi-channel element, a Dove prism (inverting prism, erecting prism) rotates the angle of the aligned direction of the multiple beams whose light intensities have been modulated, and the beams are then sampled in by means of a rotating polygonal mirror. High rates and high resolution can be achieved in optical printing devices with the aid of the use of a diffraction grating which generates multiple beams with a uniformity in terms of light intensity.

Title: Eddy current heating using wind power
Inventor: PFEIFFER BERND
IPC: F03D15/20
Filed: 1994-08-15
Abstract: Energy generated by a vertical-axis wind-driven wheel is transmitted by a shaft to a disc rotating in a heat-exchanging medium. Within the disc eddy currents are generated. There are permanent magnets stacked on either side of the disc or beside each other above the disc. No auxiliary energy sources are needed.  The generated temperature in the medium lies above 100 degC and is thus suitable for a district heating supply. The control of the generated energy is by moving the magnets closer or further away from the disc. For this purpose, the magnets are mounted on shafts with a handle.

Title: Vulcanization sleeve for repairing or retreading vehicle tyres
Inventor: SCHMERMBECK DIETER
IPC: B29D30/56
Filed: 1987-05-16
Abstract: The vulcanization sleeve described is designed to be air-tight at least in the tyre processing region to allow evacuation of air and gaz bubbles from the space between the sleeve and the tyre or the tread or tread cap, and it covers the processing region during vulcanization in an autoclave. The problem is to find a solution which while maintaining the advantages of the so-called cold process enables during vulcanization a considerable increase in the longevity of the sleeves, a simplification in handling and in particular the application by vulcanization of treads in the form of sections of otherwise endless pieces of tread. This is achieved by the fact that the vulcanization sleeve is made of a plastic foil (6) of thermoplastic polyurethane, and in the event of a partial covering of the tyre, this sleeve is provided possibly with a sealing ring (7).
