Title: Alternating light photometer with gas discharge lamp - has photo-electric transducers as radiation receivers with output signals fed to processor with scan and hold circuits
Inventor: ZOECHBAUER MICHAEL DIPL PHYS
IPC: G01N21/25
Filed: 1978-12-01
Abstract: An alternating light photometer uses a gas discharge lamp as the radiation source. A cyclically-operating beam modulator is provided to generate periodically following measuring and comparison radiations. Photo-electric transducers serve as radiation receivers. Their signals are delivered to a signal processor containing scanning and hold circuits. The processor is controlled by scanning pulses of the modulator. The switching on of the gas discharge lamp occurs for only a short time, essentially during the opening of the radiation path through the modulator. This increases the serviceable life of the lamp and hence that of the photometer and its consistency of results. A signal generated by the scanning arrangement (9) of the modulator (2) can be used to switch the lamp (1) on and off.

Title: Mechanical alphanumeric display with electromagnetic selection - has coloured flaps with sprung retainer in retracted position
Inventor: WEGENER KARL-HEINZ
IPC: G09F9/37
Filed: 1979-06-01
Abstract: A mechanical alpha-numeric display has pairs of flaps (1, 2) representing different colours for the same segment of each character operated in sequence by two electro-magnets and with a double acting mechanical lock (13) to ensure that only one flap at a time is in the display position. The electro magnets only operate for short pulses during character change. The electro-magnets operate against spring pressure, with the retracted position of the flaps tensioning the springs (11, 12). The retracted flap is held by the lock (13) until the other flap is retracted and trips its end of the lock. This prevents the flaps from striking each other. The mechanical display is simple and requires only short power pulses to change the display.

Title: Stabilising marine or fluvial sediments exposed to erosion - by depositing grout comprising e.g. clay and gravel, protecting structures in e.g. submarine petroleum fields
Inventor: PARKER WILLIAM REGINALD
IPC: E02D3/12
Filed: 1979-06-20
Abstract: A method of stabilising an erodable marine or fluvial sediment consists of depositing directly on the sediment a grout comprising a pasty or colloidal non-hardening material, pref. mud or clay, incorporating particles of a solid material, pref. gravel. The group is brought to the required position above the sediment by forcing it through an under-sea tube fitted with a mobile delivery head which spreads the group over the sediment. The invention eliminates the inconveniences of existing processes. These include using concrete, an inverse filter, rock or gravel, synthetic material, plants or bitumen plates. They are in general different to apply and costly and may not be always reliable or compatible with the environment. The method according to the invention protects under-sea structures. e.g. pipes or the feet of stands in petroleum drillings against damages produced by undermining caused by waves and currents in the sea. It supports sections of piping which have been undermined, is compatible with the environment and the bed is stable for a long period. It can be applied with precision from a ship without supervision by divers.

Viscous sludge is helped move towards the discharge position along the walls of a cylindrical centrifuge by a scraper formed of annular steel rings, with slots between wall-contacting projections, which shares the reciprocating movement of the resilient slider ring. Used partic. for purifying wine, beer, fruit juices etc., without losing these while removing the sludge in specific amts. rather than at specific intervals as with known appts.
Patent DE-2946304-A1 (DE)
Inventor: WILLIMCZIK WOLFHART
IPC: F01C3/06
Filed: 1979-11-16
Abstract: A rotary piston displacing machine for use as a pump compressor or power engine, as well as a hydrostatic coupling. The machine has a disk-shaped rotor rotatable in a housing, several similar diametrically opposed rotary vanes which penetrate the annular groove of the working space, which vanes can be joined or formed together in a second rigid rotor, the impeller, the disk-shaped rotor having a rotational axis forming an acute angle with the axis of the impeller. The disk-shaped rotor is positioned obliquely on the working space and is provided with radial slots for receiving the vanes which reach down to the bottom of the working space to sealingly lock the adjacent working chambers formed in the working space. The displacement operation takes place by the rotation of the vanes and the changing cross-section of the groove of the working space. If the cross-section of the working space approaches zero on one point of its periphery, i.e., when the disk-shaped rotor touches this point at the bottom of the working space, this displacing machine has neither a dead space volume nor squeezing points. It is sufficient if only one vane locks sealingly the adjacent chambers of the working space within the area of greatest cross-section since a stationary separating point exists already there. The shape of the cross-section of the working space, the shape and number of the vanes, and the shape of the rotors can be selected freely within a wide range. However, a certain symmetry of the rotation must be maintained, and the parts must be naturally adapted one to another. This rotary piston machine is suitable for use as a machine for displacing all kinds of freely flowing media, as well as for use as a power engine in the form of a displacer turbine.

Title: Optical sensing measurement system - responds to rapid intensity changes and suppresses low change rates using filtering comparator
Inventor: DRIESCHNER HANS-PETER
IPC: G01V8/20
Filed: 1979-12-01
Abstract: The optical measurement system i.e. for detecting the presence of a vehicle uses a sensor producing an output signal dependent on the light it receives and operates independently of light source variations caused by obscuring dirt etc. It operates economically and reliably and is easily installed and reacts to system light intensity increases but not to ambient intensity changes. Two varying threshold signals (US1,US2) are dependent on the sensor output signal (USi). One is greater and one less than the sensor signal by a given voltage level. Theshold signal variations faster than a defined rate of change are suppressed by low pass filters (5,6) whose outputs are compared with the sensor signal by comparators (7,8). A sensor light variation is only indicated when the sensor signal exceeds the upper or falls below the lower rate limited threshold.
