Title: Day and night vehicle indicator lighting - has lamp branch connected between resistance and blocking diode in series with rotary switch
Inventor: KUHN HANS-ULRICH
IPC: B60Q3/04
Filed: 1976-09-03
Abstract: The auxiliary lighting (V) such as parking light, number plate light and instrument panel display is connected in parallel to a day-night rotary switch terminal (K). The terminal leads to a blocking diode (D) in series with a resistance (R) to the negative side of the supply. At the junction point (P) with diode and resistance, a display lamp (L) is connected via a switch contact to the positive supply. The current flows by day via the display lamp (L) and the diode to the lamp circuit (V) to negative. By night, the rotary switch terminal (K) is turned to positive and the lamp current flows via the display lamp (L) and the resistance (R) to the negative pole.

Title: Solar energy converter with black porous absorber - through which gaseous or liquid medium passes in continuous flow
Inventor: SCHIEBER FRANZ
IPC: F24S10/80
Filed: 1976-09-14
Abstract: Solar energy collector has a highly porous black coloured absorber through which a liq. or gaseous medium passes in a continuous flow. The absorber is mounted in an insulated, housing with a transparent plate e.g. glass covering the surface facing the sunlight.

Title: Data-processing machine wiring - comprising fine parallel wires embedded in fluorine-contg. polymer ribbon together with perforated metal earthing sheet
Inventor: PRITSCHOW GUENTER DR ING
IPC: H01B7/08
Filed: 1976-09-28
Abstract: Data-processing machine wiring includes sets of fine wires embedded parallel to each other in a ribbon of fluorine-contg. plastic. Some of the wires are used as earth returns. To allow them all to be used as signal wires, one or more perforated metal sheets are embedded in the plastic, to serve as earths. Two methods are given. Each of the parallel signal wires are separately insulated, the metal sheet woven in and out among the insulated wires, and finally the ribbon completed with a layer of plastic on each side. Alternatively, the signal wires, without separate insulation, are embedded side by side between two sheets of plastic, a metal sheet placed at each side, and two further sheets of plastic added to complete the ribbon. The metal sheets could be either perforated metal tapes or woven tissues of metal wires.

Title: Electric incandescent lamp with anti-lock thread - has normal thread pattern interrupted by axial indentations formed by stamping before rolling of threads
Inventor: FRITZ HUBERT ING GRAD
IPC: H01K1/46
Filed: 1976-12-17
Abstract: The electric light bulb assembly has an anti-jamming screw base. It comprises a glass envelope (1) with a tungsten filament connected to the brass base and to a brass end contact (23) insulated from it by a ceramic or plastics ring (22). To allow for thermal expansion of the thread when the bulb is hot and to prevent binding of the thread in the socket which makes the bulb difficult to remove, the base thread has a number of creases (211) distributed around the base and parallel to the tube axis. Each crease is formed by stamping before the thread is rolled onto the base shell. The crease depth is that of the thread so that the thread is interrupted at intervals and the helix is divided into sections.

Title: Distance measurement using light intensity variation - uses square law of light intensity fall off with distance
Inventor: MEHNERT ERICH HERBERT
IPC: G01C3/00
Filed: 1977-01-28
Abstract: A method of distance measurement and an optical-electrical device using the method rely on light emitted from the object whose distance is to be measured. The device is pointed at the object in the same way as a rotor device, but has no moving parts and operates solely on measurement and evaluation of the distance-dependent intensity of illumination. The light beam is measured point by point and the distance T1 evaluated from the equation E1/E2 = r12/r22 where r1 and r2 from the object. One distance is determined as a reference, enabling the second distance to be determined from the measurement.

Title: Inspection machine for glass bottles - has electronically controlled device which rejects defective bottles and uses friction disc to rotate bottles on test rollers
Inventor: SCHMID CARL
IPC: B07C5/34
Filed: 1977-02-18
Abstract: The glass bottles are placed upright on the conveyor from which they are deflected by a guide onto two further conveyors of the inspection machine. A worm drive pushes the bottles with the required spacing onto the test rollers. The bottle is then rotated one and a half times by the friction disc. This motion checks that the bottle is dimensionally correct and at the same time an optical device checks that the bottle is free from cracks. The sound bottles pass along the conveyors where they are deflected by guides so that they return to the initial conveyor. Defective bottles are blown into a chute by a jet of air from a nozzle actuated by an electronic control system.

Title: Exposed sunblind bottom vertically track guided rod - has end pawls moving and locked in track notch serrations
Inventor: FRITZ GERHART
IPC: E04F10/06
Filed: 1977-06-22
Abstract: On the sunblind awning, esp. for a high-rise building, ther is a horizontal rod extending along the bottom edge, with ends led so as to move up and down on vertical guide tracks. Each end of the rod(20) has a pawl mounted on it. This is movable into a notched serration(28) on the sliding track(18) after the sunblind is raised by knocking onto top attachments(26). When it is being lowered resilient spring(30) action holds it in this advanced position. With the blind completely lowered, knocking on bottom attachments(32) causes the pawl to be moved back out of the notching, where it is held until the top attachments are knocked. This ensures that clamping is not relaxed, allowing the canvas to blow out in strong winds and twist the rod.

Title: High speed electromagnetic suspension track - has L=shaped vehicle magnets exerting vertical support and flat guiding forces
Inventor: HOLZ RUEDIGER ING GRAD
IPC: B61B13/08
Filed: 1978-01-14
Abstract: The high-performance high-speed guiding track uses an electromagnetic support and guiding system. There are two spaced T- or L-shaped iron rails (6) for electromagnetic support and guidance of a vehicle (1). The latter bears L-shaped support and guide magnets (7, 8) alternately singly or in groups one behind the other, in two lengthways rows. The support magnets (7) are in electromagnetic contact with the appropriate rail so as to generate vertical force. The guide magnet's (8) contact with their rail, causes a horizontal or inclined force to be generated. This combines the advantages of flexible guidance with those of inexpensive support and equipment construction.
