Title: Hydrostatic cylinder for location of shaft support bearing - has outlet throttle to respond to sudden load variations with bearing segment attached piston located in hydraulic cylinder
Inventor: MILLER HELMUT DIPL ING
IPC: F16C32/06
Filed: 1975-12-22
Abstract: The shaft (2) of a rotary machine such as a turbine is supported by a bearing segment (3) which has hydrodynamic lubrication. A piston (4) which is attached to the bearing segment (3), is located inside a hydraulic cylinder (7). The cylinder is connected to a hydraulic supply line (6) that includes a throttle valve (10) and a stop valve (9). Under normal running conditions, the pressure in the hydraulic cylinder is constant since the load variations from the shaft (2) are minute. During starting up of the turbine, dynamic loads are created which are several times greater than the normal running loads. Since they occur suddenly, the throttle valve (10) prevents the hydraulic fluid from escaping, thus the shaft is fully supported.

Title: Optical scanning system examining mass produced parts - uses TV camera system with digitised video output for profile assessment
Inventor: SCHIEF ALFRED DIPL PHYS
IPC: G01B11/02
Filed: 1976-02-24
Abstract: The object is placed in the field of view of the famber so that the horizontally-scanned image area is at right-angles to the vertical axis of the component (1). The video signal produced by each line of the scan is assessed by a digital processor. A certain line (n) of the scanning raster is taken as a reference and a certain number of subsequent lines (n+k) are used for measurement of the component profile. Each line output signal drives a digital counter so that: for each line of scan for a standard component a digital value can be assigned to it. Any variation in the shape of a component under test from the norm is detected by the counter and an alarm signal initiated. The system is equally useful in checking the profiles of the edges of cutting tools.

Title: Heat insulated tube for use in mine workings - haelectrically conductive outer surface connected to inner tube to prevent charge build-up
Inventor: PUTTER WERNER JAN DE
IPC: F16L59/14
Filed: 1976-03-20
Abstract: Heat insulated tube comprises inner (e.g. steel) and outer (e.g. PVC) tubes arranged concentrically with a heat insulating and resisting layer between them. The outer surface of the synthetic tube is coated with an electrically conductive layer (e.g. of thermosetting resin contg. C black).

Patent DE-2702879-A1 (DE)
Title: Solar heating system for water or desalination use - circulates unpressurised water between radiation-absorbent, plastic-coated films
Inventor: BRUECHER FRITZ
IPC: F24S10/50
Filed: 1977-01-25
Abstract: Water for swimming pools or other purposes is heated, or saltwater is vaporised, by the absorption of the heat of the sun. The water to be heated is delivered through a header pipe between two inclined films. These are joined water-tight along their edges, and the water is distributed uniformly between them, without pressure and falling naturally, exposed to the sun's radiation. At the bottom, the water is collected in a second manifold and is transferred for further use. The inclined arrangement of the films pref. consists of an absorbent film which, to increase its absorbency is coloured matt black or is coated, and a ripple surface film. This, to reduce the speed of flow of the water, and to distribute it more uniformly in a thin layer, as well as to increase its surface area, is covered with bosses of different sizes and shape corresponding to the application. The design ensures the highest degree of efficiency with the cheapest possible equipment. No additives are used in the water exposed to the radiation so tht heat exchangers liable to corrosion are not necessary.

Patent DE-2749053-A1 (DE)
Inventor: DREIKOPF KLAUS
IPC: B65H63/06
Filed: 1977-11-02
Abstract: No permanent evaluatable signal is produced when a light barrier is used to scan a thread in conjunction with a downstream dc amplifier when the width of the thread is substantially smaller than the diameter of the smallest possible focal spot, since the amplitude of said signal is so small that it is of the order of magnitude of the signals produced or occurring due to other disturbing influences. The problem becomes soluble when an ac amplifier (4), whose output is connected via a Schmitt trigger (5) and a monostable multivibrator (6) to an evaluation device (7), is connected downstream of a reflected-light barrier (2) via a capacitor (3). If thread pieces directed transverse to the conveying direction are conveyed along a thread track (1), said pieces pass the focus of the reflected-light barrier (2), whose light-receiving part sends a short, weak pulse via the capacitor (3) into the highly-amplifying ac amplifier (4). The amplified pulse switches the Schmitt trigger (5), which flips the monostable multivibrator. The downstream evaluation device (7) evaluates the pulses. <IMAGE>

Title: Switched mode power supply with oscillator for tv receiver - has supply for drive stage obtained from output connection of output stage
Inventor: DIETHELM OTTO ING GRAD
IPC: F42C11/02
Filed: 1977-11-04
Abstract: The supply unit is designed for use with a TV receiver. It has an oscillator, a drive stage, an output stage and an output transformer. The supply voltage for the drive stage (3) is obtained from the output of the output stage (4) by rectifying the output pulses of a secondary winding (7) of the output transformer (10). The output stage oscillates freely whilst the unit is on and is coupled back to the transformer secondary. This feedback loop is broken when the unit is off. The advantage lies in needing no additional transformer.
