Title: Sensor measurement spring with triple bending beam
Inventor: THIESSEN KLAUS
IPC: G01P15/12
Filed: 1982-05-29
Abstract: The invention describes a sensor with a triple bending beam. The middle bending beam has the greatest cross-section, so that it essentially determines the spring rate or the characteristic frequency of the sensor. The strain gauges are fitted to the upper or lower bending beam of the triple bending beam. The sensor according to the invention makes it possible, especially in an acceleration sensor, either to increase the output signal of the sensor considerably or, if the output signals remain the same, to increase the characteristic frequency of the sensor considerably. A sensor according to the invention is hence particularly suitable for accelerometers. <IMAGE>

Title: Process for extreme drawing of crystalline polymers under high pressure
Inventor: MEIER DALE J PROF DR
IPC: B29C55/02
Filed: 1982-08-06
Abstract: A solid, crystalline, organic polymer is converted into a filament, rod or film by means of extreme drawing of the same at a temperature in the range of 70 DEG C below to just below its melting point at the operating pressure, the polymer, during and directly after the drawing, being subjected to a hydrostatic pressure of at least about 500 atmospheres, which is transmitted by a liquid medium which is inert to the polymer. High-density polyethylene and isotactic propylene are preferred polymers. A drawing ratio of at least 20:1 and up to 60:1 can be used. The pressure can be up to 2500 atmospheres or above. The drawing rate for polyethylene is over 500% per minute. The extreme-drawn products are transparent, essentially free of internal pores and have, in the case of polyethylene, very high moduli of elasticity in tension of up to 65 to 70 GPa (gigapascals).

Patent DE-3333071-A1 (DE)
Inventor: GEIGER ERICH
IPC: H04N11/06
Filed: 1983-09-14
Abstract: An analog digital conversion is provided for two color difference signals, for example for a recording according to a timeplex method. The color difference signals are adjusted in their amplitude at the input of the analog digital converter such that the modulation range of the analog digital converter is always fully used independent of the original amplitude of the color difference signal. The amplitude is restored back to its original value after a digital to analog reconversion. This results in an improvement of the signal to noise ratio during the transmission. The amplification provided to the various signals can be controlled by comparator circuits comparing the signal level with a reference signal.
