Title: Beam intensity control for semiconductor laser - has photodiode whose current leads are galvanically separated from those of semiconductor laser
Inventor: PFEIFFER EUGEN ING GRAD
IPC: H01S5/022
Filed: 1979-08-03
Abstract: The semiconductor laser has two light emitting surfaces, one being optically coupled to a glass fibre, while the other one being optically coupled to a photodiode (4) for detection of the laser radiation intensity. The current leads (32,33) of the laser (33) and the current leads (42,43) of the photodiode are galvanically separated. Further glass fibre is preferably arranged between the second light emitting surface inthe form of a window (37) and the photodiode. Alternately, an optical component may be inserted between thin second light emitting window and the photodiode. This arrangement prevents the photodiode current to be affected by the laser current which is of much greater strength. Such an effect would limit the laser modulation to a few Mbit. The laser assembly is mounted in an electrically conductive housing (1).

Patent DE-2946493-A1 (DE)
Title: Automatic contactless optical evaluation of reflecting surface quality - using photoelectric transducers and point or laser illumination source
Inventor: DREYBRODT WOLFGANG PROF DIPL P
IPC: G01N21/55
Filed: 1979-11-17
Abstract: An arrangement for automatic contactless evaluation of the quality of reflecting surfaces enables the quality factors to be converted into electrical signals by photoelectric transducers such as phototransistors, photomultipliers, or imaging tubes. They provide practical, reliable, and economical evaluation of large surfaces. An optically reflected light field is created by point or parallel light illumination from a laser or point source. The field is scanned by the photoelectric transducers whose signals are evaluated to derive the quality factors. An image of the intensity distribution of the reflected light may be formed on a ground glass plate to enable direct visual evaluation instead of automatic sensing and signal evaluation. The quality characteristic may be the variance of the measured signal divided by its square.
Patent DE-3001770-A1 (DE)
Inventor: ZOBELEY FRITZ
IPC: B66B9/04
Filed: 1980-01-18
Abstract: In such a piston/cylinder unit (1) which serves to drive an elevator car (3), the cylinder (7) is mounted in the foundation on a support (8) which at the same time constitutes the cooler for the hydraulic fluid. The feed and discharge of the hydraulic fluid to and from the cylinder (7) is effected here via the support (8), which is constructed as a hollow cylinder and has cooling ribs (9) on its outer surface. The hydraulic fluid heated during the work cycle can be recooled via these ribs instead of a separate cooler, which is usually difficult to accommodate. <IMAGE>

IPC: G21C7/10
Filed: 1980-05-27
Abstract: A gas-cooled, high-temperature reactor of pebble bed type comprises an active zone of spherical fuel elements in a pressure vessel having a (steel) liner. The top liner is perforated by pipe lengths through it and the concrete top of the vessel; guide tubes for shutdown and control rods are detachably suspended from the bottom ends of these pipes.

In a preferred embodiment the recesses are each formed as an annular groove typically of trapezium cross-section. At least one of these grooves is wider than the diameter of a ball. For a pebble bed reactor where control andshutdown rods pass through the top cap of the vessel and are guided in tubes inside the vessel. The connection between each of these tubes and the associated pipe length through the vessel top cap is easily made by the device shown, which requires no welding or other complicated operations and can be readily disconnected.

Patent DE-3115566-A1 (DE)
Title: Method for producing gas-filled double glazing and plate press for implementing the said method
Inventor: THIES WOLFGANG
IPC: E06B3/673
Filed: 1981-04-16
Abstract: The invention relates to a method for producing gas-filled double glazing. A first plane of glass is placed on a frame in a sealing manner, and then this pane of glass, which has been provided with the frame, is introduced into a chamber which contains the filling gas. In this chamber, the second pane of glass is pressed onto the opposite side of the frame, also in a sealing manner. A plate press, which has been modified in accordance with the invention, is used to implement the method, in the case of which two mutually opposite sides are provided with a flexible seal. The two other sides are in each case provided with a pressure lock, through which the first pane of glass, which is provided with the frame and the second pane of glass are introduced into the plate press. The pressure locks are preferably ball locks, and may also be double locks if so required to reduce the amount of gas lost. The filling gas is situated inside the plate press at a pressure which is slightly greater than the outside pressure. The gas which is lost when the locks are opened is compensated for by a filling gas feeding pipe which leads to the interior of the plate press. The method and the corresponding plate press make it possible rapidly and completely to fill the space in the double glazing with the desired filling gas.
