Patent DE-2513376-A1 (DE)
Title: Protection circuit for motor vehicle - misconnects battery when accident occurs by actuating relay via mercury impact switch
Inventor: FUCHS HELMUT
IPC: F02P11/02
Filed: 1975-03-26
Abstract: The protection circuit, for motor vehicles, disconnects the battery from all its load circuits when an accident occurs and thereby prevents fire caused by electrical sparks. A mercury switch is connected in series with a secondary relay coil across the battery and actuates the relay when the vehicle experiences a sudden impact or rolls over etc. The secondary relay's contacts connect a main relay's coil to the battery. THe main relay operates and its contacts disconnect the load circuits from the battery. The circuit actively disconnects by application of a voltage rather than by its removal.

Title: Versatile grill cooker with central upright heating unit - holders for several coaxial spits for maxinium heat use
Inventor: FINK ALBERT
IPC: A47J37/04
Filed: 1975-04-10
Abstract: A grill cooker has a heating unit (10) mounted upright on a support frame (12 to 16) whilst several stations for the grill spits (30), mounted grouped round the heating unit on the support frame have battery-fed drive units (20) which have drive sockets (24) in which the spits can be vertically inserted. Using independent grilling stations allows optimum use of the heat radiated from the heating unit and the multiple grill unit allows each station to be used for grilling a different food. The heating unit is preferably connected on the underneath to a collecting tray (11) so that in the case of a charcoal heating unit the ash can be readily collected.

Title: Modulated light video recorder - uses modulation by variation of scanning speed at full intensity to avoid beam power loss
Inventor: HARTMANN WERTHER
IPC: G11B7/125
Filed: 1975-07-02
Abstract: An optical method for recording video signals is esp. by means of a modulated laser light beam tracing a spiral track on a recording medium. The power loss involved in intensity modulation by passing the beam through a variable stop aperture is avoided. The modulation is effected by varying the time of exposure whilst maintaining full intensity of the beam. This may be effected by continuous variation of the relative velocity of beam and recording base caused by deflection of the beam backwards or forwards along the direction of the track. The rigid, rectangular body (23) has a mirror (22) on one side. A piezoelectric oscillator (20, 21) is mounted at opposite ends of the body (23). An apparent widening of the approaching beam (26) leads to the formation of the recording bundle (27).

Title: Chopper circuit using transistor bridge - has capacitance divider connected across input and connected to transformer primary
Inventor: HANKE MARTIN
IPC: H02M3/337
Filed: 1975-08-14
Abstract: The chopper circuit comprises four transistor (1-4) connected in a bridge circuit with the output transformer primary (5) in one diagonal and the d.c. input on the other. The switching losses in the transistors can be reduced by fixing the transformer primary mid-point potential. The primary mid-point (15) is connected to the mid-point (14) of two identical capacitors (12, 13) connected across the d.c. input terminals (10, 11). This holds the transformer mid-point voltage approximately constant and reduces the turn-off losses of the slowest transistor. Losses may be further reduced by adding an inductor (18) in the primary lead between the capacitor connection point and the bridge connection point.

Abstract: A fire alarm system uses parallel coupled sensors on a common loop and responds to changes in resistance to trigger the alarm. An additional facility enables the system to recognise faults in operation of the equipment. The circuit consists of an indicator stage with an alarm state indicator and a relay indicating either normal operation or operational fault. A pulse voltage generating circuit and status checking stage operate over voltage transformers with the alarm loop. The alarm loop has a number of ionisation chamber sensors in parallel with a coupling Zener diode.

Title: Hanging garden hydroculture container - consists of vertical of zig zag shaped sheets preferably suspended from rail and with grooves for seeds
Inventor: ISSEL WOLFGANG DIPL PHYS DR IN
IPC: A01G31/04
Filed: 1975-11-19
Abstract: The grass grows on a vertical wall (1) which, for example, can be made of fabric reinforced rubber which is suspended by means of two rollers on a continuous track. Each side of the wall (1) has horizontal grooves (3) in which the seeds are placed. Two spray-pipes (4) moisten each side of the wall with a nutrient solution which trickles downwards through perforated grooves, to moisten the seeds. After the seeds have been sown, the vertical walls are placed in an environment offering optimum germination and quick growing conditions, such as natural daylight. After leaving the growing location, the walls are harvested or rolled up and taken where the fodder is needed. The harvested walls are finally conveyed through a cleaning chamber, before being freshly sown with seeds. The walls can also be zig zag shaped, with each sloping side used for growing, and a row of knobs preventing the seed from falling off.

Abstract: In an electrical recording material signal-coded electrical energy causes a change in the material's surface to a signal-analogous relief structure opt. with a concomitant colour change. The material comprises a first, conductive layer or a carrier made conductive by known techniques. A second intermediate layer serves to inject electrons into the system and comprises special macromolecular materials which forms coordinate bonds with semiconducting or photoconducting metal cpds, or forms chelate-type complexes and/or H-bonds or become polarised by the signals induced electrical field. A top layer is also provided which contains semiconducting metal cpds., ionic crystals and, opt. other additives as well as a binder. A novel method of recording/reading information is achieved. Reading is effected by measuring reflection changes using visible light.

IPC: F16H15/20
Filed: 1976-10-27
Abstract: The steplessly adjustable friction wheel drive has friction bodies sliding on axes intersecting at a single point, thrust by an external support against an inner roller body. The driving and driven shafts and roller body are coaxial. The roller body (AK) is concave and the friction bodies (RK) are convex, and the roller body also slides. Independently of the setting of the friction bodies, the tangent points between it and the friction bodies always lie on a line passing through the intersection point of the axes. The bodies can be pressed against each other by a pre-loading mechanism causing the roller body and the support to slide in relation to each other, and dependent on the torque.
