Title: Control circuit for quasi-analogue light strip display - has anodes and cathodes of luminous elements reactively joined together
Inventor: SCHENK CHRISTOPH DIPL PHYS
IPC: G01D7/00
Filed: 1975-03-29
Abstract: A control circuit for a quazi-analogue light strip display in which the luminous elements are double indexed. Anodes of luminous elements with the same first coding digit are joined together, and cathodes of luminous elements with the same second digit are also joined together. The light strip display is controlled by a time division multiplex method so that luminous elements of the set activated at the anode are illuminated, where position number is smaller than or is equal to the number determining the end of the luminous strip to be illumionated, allocated to the analogue input variable.

Title: Pressurised pipeline sampling pipe - has sample vessel with moving piston and magnetic valves for pressure reduction
Inventor: HOLSTE DIETER
IPC: G01N1/20
Filed: 1975-04-02
Abstract: The device is for automatic sampling from a pressurised feed pipe line. It has a cylindrical sample collection venel (15) attached to the pipeline (8) by a sampling pipe (4) at its front side, within which a sealed piston (9) is mounted. The sample venel (1) is filled with water moving the piston (9) up to the sample inlet and the water input pipe (10) is closed and the cutlet-off slide (5) of the sampling pipe (4) is opened to take up the pressure within the feed pipe (8). This pressure is released at intervals by means of a magnetic valve, allowing passage of sample to the collector vessel. A pressure equaliser (13) in front of the valve (14) is used to reduce the pressure difference developed in the feed pipe (8) during sampling.

Title: Pneumatic shock absorber for engine - has pressure chamber and flexible piston to produce damping action
Inventor: WAIBLINGER FRIEDRICH
IPC: F16F9/04
Filed: 1975-04-10
Abstract: The pneumatic shock absorber is used for an engine mounted in a vehicle frame. The body of the shock absorber has two flanged cup-shaped halves (14, 18) which are clamped together also the flanges (10) by equally-spaced bolts (11). A barrel-shaped piston inside the housing consists of two flexible rings (8, 9), held together by a mounting bolt (4) and two flanged support discs (6). A flexible membrane (7) is clamped between the support rings and the flanges of the housing. Thus the upper half of the shock absorber forms an airtight chamber (21) which can be pressurized by an inlet valve (17). The air in this chamber is therefore providing the required damping under normal operating conditions. When excessive loads are applied, the flexible piston element (8, 9) assist the damping action.

Title: Pipeline butt welding device - with seals forming chamber around butt joint filled with inert gas
Inventor: PANZER WALDEMAR
IPC: B23K9/32
Filed: 1975-05-20
Abstract: An auxiliary device for butt welding operations, esp. for pipelines, consists of two sealing elements which are introduced to both sides of an intended butt weld seam and form a sealed chamber around the weld. Inert gas is introduced to this chamber through a sealing element at one end and it escapes to atmosphere through a tube in the other element or through the butt joint. This prevents oxidn. and results in welds of higher quality without having to fill the complete pipeline with inert gas. The inert gas consumption is much less and it can be controlled for optimum weld quality.

Title: Ink ribbon movement reversing system for printing unit - has one ribbon spool remaining in unit and carrying non inked ribbon serving as anchorage
Inventor: BRANDENBURG KLAUS DIPL ING
IPC: B41J33/00
Filed: 1975-06-26

Title: Prerolled concrete reinforcing bar - producing depressions to reduce the work of forming ribs in finish rolling
Inventor: SCHWARZ WILHELM
IPC: B21B1/16
Filed: 1975-12-24

Title: Overload protection for electric machine - is disconnected when tripping value is exceeded in consequence of pulses received by several threshold value indicators
Inventor: AMEY WALTER DIPL ING
IPC: H02H6/00
Filed: 1976-01-08
Abstract: The tripping value is set in accordance with the machine rated current. Tripping value of the overload relay (6) is automatically changed, depending on an overcurrent appearance, and when the overcurrent disappears it is reset to the value for operation with rated current. A blocking unit permits the machine disconnection after the tripping value has been reset, only if the machine current exceeds a specified value. In one embodiment, the motor (1) is connected through a current converter (5) to the load switch (2) and power network (3). The switch blade is mechanically coupled to a load coil (4) which receives the output of the relay circuit (6). The current line is connected to two threshold value units (7,8) in parallel, one of which (7) is in series with a timing unit (16).

Title: Solar radiation energy collector - has zig-zag formation and parabolic mirrors alternatine with absorber surfaces
Inventor: RUECKSTAEDTER HANS
IPC: F24S23/74
Filed: 1976-04-20
Abstract: The collector is constructed as in 2552598, but has alternate sections of absorber surface and mirror which are arranged at angles to each other so that the max. incident radiation is reflected onto the absorber surfaces.
