Title: Thickness measuring apparatus using ultrasonic technique - with fluid column standing waves produced by frequency modulated generator
Inventor: KROEGER HANS DIPL ING DR
IPC: G01B17/02
Filed: 1975-03-15
Abstract: The equipment consists of a high frequency generator (1) using variable-capacitance diodes (7) and frequency modulated by a saw-tooth generator (6), the amplified oscillator output (8, 9) being connected to a ring-modulator (2) and to a frequency-to-voltage converter (12). The ring-modulator output drives an ultrasonic transducer (3) coupled through a fluid column to the measured object (5). Standing waves are maintained in the liquid when the oscillator and resonant frequencies correspond. The liquid column resonant wave passes through a high-pass filter to a detector (13), three-input gate to a sample-and-hold circuit. A window-detector selects the required operating frequency band and in combination with the generator (6), AND gate circuit and DC signal from the frequency converter (12) causes the sample-and-hold circuit to provide a DC output which is proportional to the thickness (d) of the test-piece.

Title: Pressure transducer diaphragms production method - uses sintered pulverised metal material for extreme durability
Inventor: BROSA ERICH
IPC: G01L7/08
Filed: 1975-12-13
Abstract: The production method for the manufacture of wear-resistant diaphragms for pressure transducers uses sintered pulverised metal as the base material. The powder is subjected to pressure in a die to produce the required form of diaphragm. Cup-shaped components can be produced with greater dimensional accuracy by employing electrochemical erosion. The diaphragm (3) can be mounted in the transducer element by heat-shrinking onto a carrier (6) which is similarly manufactured from sintered material. The diaphragm carrier then forms the transmitting element between the diaphragm and the actual transducer cell (8). This method produces an element of extreme wear-resistant properties.

Title: Directional aerial for surveillance of rooms or spaces - has cylindrical parabolic reflector and strip radiator for optimum sensitivity
Inventor: LINDNER KURT DIPL ING
IPC: H01Q19/15
Filed: 1976-02-18
Abstract: In surveillance systems for rooms or open spaces intended to detect intruders the area close to the aerial is difficult to cover. If the sensitivity is too great spurious alarms may be generated, e.g. by vegetation moving in the wind. If too low, intruders may pass undetected if close to the aerial. This defect is overcome by using a parabolic reflector (R) which is part of a long cylinder (L). The strip radiator (E) is placed on the line forming the focal line of the reflector. The length of the reflector (L) is chosen to be at least approximately equal to the square root of ZXW, where Z is the distance between sondes or aerials and W the wavelength of the electromagnetic emission.
