Title: Welding device for inert-gas welding, with observation of the welding spot by a fibre-optic waveguide
Inventor: GAWLIK NORBERT
IPC: B23K9/095
Filed: 1985-01-30
Abstract: The invention relates to a welding device, in particular for automatic arc welding under inert gas, consisting of a welding torch and an inert-gas feed connected to it. In order to optically scan the welding spot or the arc during the welding operation, an optical scanning system is connected to the inert-gas feed. The scanning system has a fibre-optic waveguide (quartz fibre, quartz-fibre bundle and the like) which produces the optical transmission to an emission spectrometer, by means of which the radiation emitted from the welding spot is determined spectroscopically, it being possible to control the welding operation for exact weld scanning by means of an electronic analysing system allocated to the emission spectrometer. According to the invention, the fibre-optic waveguide is arranged at the inert-gas feed in such a way that the path of rays from the welding spot to the fibre-optic waveguide leads through the inert-gas stream. In this way, the path of rays is kept free of fume and dirt particles and the like to a very large extent during the welding operation.

Title: Optical switching device
Inventor: ROY RICHARD D
IPC: H04B10/213
Filed: 1985-03-27
Abstract: Optical switching arrangement having an optical light guide between a light source and a light detector. The light guide is constructed with one or more intestices, and switching is brought about by moving optically coded diaphragm elements along one of the intestices. A microcomputer is connected to the detector and can be programmed in order to identify from the coding which screening element has been moved, so that a single computer input is used to read a multiplicity of switches.

Patent DE-3643918-A1 (DE)
Title: Coking system
Inventor: NASHAN GERD DR
IPC: C10B5/02
Filed: 1986-12-22
Abstract: Coking system in which feedstock mixtures are charged batchwise to an indirectly heated reactor, and a plant in which a plurality of reactors are combined into reactor blocks. Coke oven plants have hitherto been constructed in a battery type of construction, a battery being associated with a relatively large number of coke ovens which are dependent on one another structurally and in terms of heating technology. In the novel coking system, it is intended that the individual reactors should be operable independently of one another structurally and in terms of heating technology. The reactor is designed as a large-volume coking reactor which is bounded by two rigid walls and whose chambers have plane-parallel heating walls which are supported rigidly against the reactor walls and have vertically arranged heating flues fitted with separate controlling and/or regulating elements. The regenerators or recuperators are arranged between the heating walls and the side walls. The large-volume coking reactors are preferably combined into reactor blocks without the individual reactor losing its independence, that is to say, for example, that it can be exchanged or repaired without adversely affecting neighbouring reactors. The preferred field of application is the coking of feedstock mixtures based on bituminous coal. <IMAGE>

Title: Bend-compensating roll
IPC: D06C3/06
Filed: 1987-01-10
Abstract: The flexurally elastic coupling between the roll core and the roll shell of the bend-compensating roll is effected by a back-up ring, the radially aligned annular disc of which is provided, both on the outside and on the inside, with axially aligned flanges clamped to the associated shell by way of spaced clamping ring pairs. Although a 100% frictional connection is thereby achieved between the back-up ring and the roll core, on the one hand, and between the back-up ring and the roll shell on the other, the elasticity of this connection is ensured by the annular disc, which is preferably of spoked design. <IMAGE>

Title: Method of contact-free detection of ultrasonic waves in a specimen
Inventor: ARNOLD WALTER DIPL PHYS DR
IPC: G01H9/00

Abstract: In a method of detecting ultrasound at rough surfaces with the aid of optical interferometry, a phase-conjugating mirror is used to restore the original beam quality after reflection at the rough surface. For the purpose of phase conjugation, a crystal or a liquid is used for four-wave mixing, a pump beam being generated with the aid of a separate laser or by beam splitting of a single laser. It is also possible to use a crystal which shows the self-pumped phase conjugation.
