Title: Carbon di:oxide wave guide laser - uses mirrors mounted on bellows end covers for accurate alignment and decoupling of thermal expansion of body
Inventor: SEPP GUNTHER DIPL PHYS DR
IPC: H01S3/03
Filed: 1980-07-26
Abstract: The laser body (10) is formed as a cylinder made of ceramic material and has bores (14,15) for resonator rods (12), water cooling, gas reservoir and electrodes. Central to the laser body (10) is the bore hole for the capillary (13), and in addition, radial bores serve as electrode inlets and for connection of the gas reservoir to the capillary (13). At both ends of the body (10), the mirror holders are glued or fixed and fulfill the function of gas reservoir cover plates. Each mirror mount is so constructed that it firstly acts as a centralisation for the resonator skeleton rods, and secondly carries the resonator mirror (18) allowing satisfactory adjustment to one another and to the capillaries. They also decouple the thermal expansion of the laser body (10) and resonator skeleton (12) since they are mounted on bellows (19). The quartz rods are protected from the environment and are shock proofed which allows the laser to be used in mobile operation.

Title: Tertiary alcohol prepn. - by reacting iso-olefin or hydrocarbon mixt. contg. iso-olefin with water in the presence of a catalyst
Inventor: OKUMURA YOSHIHARU
IPC: C07C29/04
Filed: 1980-08-06
Abstract: Tert. alcohol is prepd. by allowing isoolefin or a hydrocarbon mixt. contg. it to react with water in the presence of a solid catalyst. Improvement is that neo type polyhydric alcohol or its deriv. is present. The velocity of hydration of isobutylene and the conversion are promoted, and tert. butyl alcohol can be obtd. in high yield while suppressing undesirable side-reaction. A neo type polyhydric alcohol has a considerably higher b.pt., which makes it easy to separate from tert. butyl alcohol, therefore, the polyhydric alcohol can be used repeatedly. Isobutylene can be isolated from a hydrocarbon mixt. contg. isobutylene by the above method.

Title: Device for measuring displacement, speed and/or distance
Inventor: GAERTNER WALDEMAR DIPL PHYS
IPC: G01P3/36
Filed: 1981-03-16
Abstract: In devices for the contactless measurement of displacement, speed and/or distance with the aid of grating/grid sensors, there is the problem that after they have been aligned the grids are no longer permitted to move relative to one another. To date, it has been possible to fulfil this requirement only with difficulty. The invention proposes mounting the grids (6,7) fixed on abutting external faces of a splitter tube (11) whose partially transmitting mirror (8) is illuminated by the optical system (4) of the device. The grid representations are converted into electric signals by photosensors (14, 15) and fed to a differential amplifier (16). The latter feeds a display unit (17). <IMAGE>

Title: Gas turbine set, in particular with combined internal and external combustion
Inventor: WEILER WOLFGANG DIPL ING
IPC: F02C6/00
Filed: 1981-03-30
Abstract: The present gas turbine set has, inter alia, a power turbine downstream of the compressor drive turbine of the gas generator, as well as at least one heat exchanger provided for the purpose of optimising the course of the process. In order to be able to operate the gas turbine set with as low as possible a demand on high-grade fuels, in a preferred embodiment the set is to have a low-pressure primary combustion chamber with a downstream heat exchanger, and a high-pressure secondary combustion chamber. The intention is for the primary combustion chamber to be assigned to the operating process downstream of the power turbine, for the secondary combustion chamber to be assigned upstream of the compressor turbine, and for the heat exchanger to be assigned with its cold path between the compressor and secondary combustion chamber but with its hot path between the primary combustion chamber and the gas outlet (exhaust), and thus to design the primary combustion chamber for operation using inexpensive fuels, for example of fossil type.
