Title: Passive IR intruder location alarm - sweeps over monitored region and detects changes from previous sweep, using timing pulses from encoder
Inventor: BOOTH CHRISTOPHER HUGH
IPC: G08B13/19
Filed: 1979-03-23
Abstract: Infra-red radiation (3, 4) from the region to be monitored is reflected by an inclined mirror (6) on to a concave mirror (13) which focusses it on an infra-red detector (14). The inclined mirror is rotated about a vertical axis by a drive motor (8) and the field of view of the detector is swept continuously round. After amplification and filtering, the detector output is converted to digital form, synchronised by timing pulses from an encoder (16, 17) on the mirror shaft (7). The digital signals are fed into a shift register whose length corresponds to one rotation of the mirror. The register output is continuously compared with its input to determine whether an intruder has caused any significant change since the previous rotation. If so, the alarm is given and the direction of the intruder is indicated.

Title: Inertially operated camera for car - has shutter released by roller on inclined plane
Inventor: RENTZSCH MANFRED
IPC: G03B17/38
Filed: 1979-05-28
Abstract: An inertially operated camera for fitting to a car has the compact camera (2) held in a mounting with an inertial switch (5) on the one side to press the shutter release above a set retardation. A time delay is built into the release switch so that the resulting pictures represent a set condition after application of the brakes, or after impact. The inertial switch has an inertial mass which rolls on a first cam slope. The slope alters so that the mass accelerates and strikes the release lever. It rolls back to the start so that subsequent retardations are recorded on the automatic camera, mounted behind the windscreen.

Title: Foil-type press-button switch - has printed contacts on top foil and baseplate separated by perforated insulation foil
Inventor: TESSENDORF GUENTER ING GRAD
IPC: H01H13/807
Filed: 1979-06-29
Abstract: Simplified assembly of foil-type press-button switch is due to the application of silver paste screen printing technique for forming the printed contacts and conductors. In addition, multiple foils carrying the printed circuits increase the functional capacity of the switch for applying in cars, washing machines or radio and tv sets. In its simple form the switch comprises a cover foil (I) of insulating material featuring markings (4) on the top surface indicating the pressing zone for switch actuation. The bottom surface of the foil carries printed contacts with conductors leading to edge connection for leads (5). The foil is separated from an insulating base plate (3) whose upper surface (8) carries corresponding printed contacts and conductors with end termination for leads (6). The separation is ensured by a foil (2) featuring holes (16) in the zones of contacts, the separation foil provided with adhesive on both sides so that it adheres to the top foil and base plate when the assembly is pressed together.
Patent DE-2930659-A1 (DE)
Title: Automatic phase adjustment in coherent TV carriers - in accordance with phasing pattern corresp. to barker codes by using IF with continually changing phase
Inventor: KRICK WOLFGANG DIPL ING
IPC: H04J1/18
Filed: 1979-07-26
Abstract: To avoid high summation peaks resulting from a number of modulated TV carriers using the same transmission line, measures such as setting up a fixed phase relationship between the carrier waves are insufficient. It becomes necessary to provide for a continual automatic adjustment of the phases in order to reduce to a minimum inter-and cross modulation interference. The invention prescribes a method for setting the phase relationship of neighbouring carrier channels in accordance with a phasing pattern that corresponds to the Barker Codes characteristic for Pulse Compression codes. This is achieved by including into a frequency conversion channel (AX) a phase regulator loop (PLLS) which is controlled by a phase setting member (PE) and the input from another generator (fo). An intermediate frequency generator (ZG1), for example at 38.9MHz, is applied to the sending converter unit (ZF/HF) as well as to the modulation circuit of the receiver unit phase setting stage (PLLE). By means of a mixer stage contained in the regulator loop (PLLS) the thereby generated intermediate frequency has a continually changing phase which is compared with an intermediate frequency of a reference carrier pair, and the result is used to modify the phase of Ax as well as all neighbouring channel pairs until the total phase pattern corresponds to the optimal distribution over the carrier bundle.

Title: Periscope synchronism verifier for e.g. armoured vehicle gun - uses mechanically and electrically perturbation factors produced in angle transmitter
Inventor: FRANCKE ERWIN
IPC: F41G3/32
Filed: 1979-12-19
Abstract: The system for verifying the synchronism of the line of sight of a periscope with elements to be aligned on objectives, e.g. a gun on an armoured vehicle, comprises producing the image of an optical verification mark in the eyepiece of the periscope. The mark is projected by the periscope and is reflected by a mirror fixed on the gun. A reflection image corresp. to the verification mark is produced in the eyepiece. The reflection image is made coincident vertically and laterally with the control mark of the eyepiece by adjustment of the mirror in the zero position of the gun and of the line of sight of the periscope. The gun is then brought into the elevation zone and the deviation of the reflection image from the control mark is measured vertically and laterally.
