Title: Radio direction finding beam angle determn. - uses measurement of sine and cosine of strongest signal to determine incidence angle
Inventor: FLIEGE HANS-JOACHIM DIPL ING
IPC: G01S3/14
Filed: 1976-11-27
Abstract: The method automatically determines the angle of incidence of a radio direction finding beam. It determines the angle of two beam with the largest signal amplitude from more than one beam of quasi-coherent or incoherent light. The angle is derived from several measurement of sine and cosine which are summed to produce total sine or cosine values. The sine value is divided by the cosin value to produce an average tangent value and the arc tangent of this value is computed to produce the angle value.

Title: Fixed length frequency sampling circuit - has high frequency oscillator output synchronised with data signals
Inventor: TRETOW JOCHEN ING GRAD
IPC: H04L27/20
Filed: 1977-01-29
Abstract: The fixed length sampling of an oscillator to produce telegram sequences is simplified by synchronising with the high frequency oscillator output. The telegram switching stage (1) generates outputs to a Schmitt trigger stage that controls (2) the sampling of a high frequency oscillator. A zero crossing detector switches on the oscillator output and the control stage provides synchronisation with the data. The oscillator includes additional capacitance that operates during the zero crossover.

Title: Spring loaded plunger of ski binding - also operates brake lever by rack and pinion drive
Inventor: LANGBAUER JOSEF
IPC: A63C7/10
Filed: 1977-03-14
Abstract: The toe clamp (12) on a safety ski binding also includes one or two brake levers (16) which are released when the ski becomes detached from the ski boot. A spring loaded plunger (14) which is depressed when a boot is located in the ski binding, is also part of a rack and pinion drive together with the brake lever. When the plunger is released due to the removal of the boot, the spring force pushes it outwards. This causes the brake lever to swivel to its active position (16a) where it protrudes below the lower surface of the ski, thus preventing the escape of the detached ski.

Title: Decorative effect for jewellery - uses sensors controlled by waves to change shape, colour or brightness of jewellery articles
Inventor: HOHENBERGER WILHELM
IPC: A44C15/00

Title: Increasing data content of telemetry signal - using logarithmic transfer characteristic during coding
Inventor: BLUM ALBERT DIPL ING
IPC: H04B1/66
Filed: 1978-07-22
Abstract: The remote measuring system periodically samples the variable being measured and codes the sample for transmission. The transformation employed to code the samples has logarithmic characteristics. A logarithmic amplifier is located before an A/D converter or alternatively a high-resolution A/D converter is used followed by code conversion using a code conversion memory. The advantage lies in reducing the inaccuracy in measurements introduced by coding for transmission.

Title: Assembling multiple contact pin plugs - by stamping pins from metal strip, attaching to strip contacts, automatically cutting off and supplying to assembly point
Inventor: DREISBACH BODO DIPL ING
IPC: H01R43/20
Filed: 1978-11-03
Abstract: Contact pins are mounted in a row in an insulator, and are shaped as blades at one end and as wrapping pins at the other. They are held on a stamped out strip, cut off and separately delivered to the assembly point. A programmed assembly with different contact pins is carried out by the use of an adjustable strip feed. Cutters cut the required number of different contact pins from the strip coils in one operation. Flexible, changeable guiding channels connect the cutters to the assembly points. Their number corresponds to that of contact pins in the plug. This arrangement enables different contact pins to be inserted so that, e.g. the earthing contact engages before the others to prevent flash over between contacts. The pins can be mounted in selected positions so that some positions can be left blank.
