Title: Measuring effective impedance of capacitor from generator frequency - by using square-wave generator to eliminate residual capacitances
Inventor: LAMBECK MARTIN PROF DR ING
IPC: G01D5/24
Filed: 1980-07-25
Abstract: The method overcomes the problems of capacitive components not influenced by the measurement parameter and of oscillator amplitude stabilisation. It gives information concerning the effective impedance component rather than just the apparent impedance. This is achieved by using a square wave generator. For measurement of the thickness of insulating layers on insulated metal bodies an earthed electrode is attached to the insulation so as to form an auxiliary capacitor with the metal body which is connected in series with the measurement capacitor. The capacitance is derived from a voltage measured against time. The method is applicable where the capacitor is used as a distance measurement transducer or for measuring the dielectric constant of the medium contained in the capacitor.

Title: NC machine tool for furniture manufacture - has upper and lower tool holders which operate simultaneously
IPC: B27M3/18
Filed: 1980-12-12
Abstract: Wooden furniture is manufactured on a numerically controlled machine tool. The machine tool has a base (1) with uprights (2) which support guide beams (3). The workpiece (13) moves through the machine on a chain or belt conveyor (4) and passes between an upper tool holder (9a) and a lower tool holder (9b). The tool holders are also able to move laterally on guides (7) and longitudinally on guides (8). As the workpiece moves through the machine work is carried out simultaneously on both faces by tools carried by the tool holders. The speed of production is thus increased and the velocity of the workpiece is independent of the dwell time between successive operations. It is also possible for operations involving tool movement in both longitudinal and lateral directions to be performed.

Title: Sensor instrument
Inventor: WILL GEB KLEIN
IPC: G10H1/32
Filed: 1981-02-18
Abstract: The sensor instrument (Sensista) is a single-surface, mouldable, movable height-variable key panel of plastic compound and there is no need for an unambiguous finger/key correlation. The novel key panel is moved with whole (whole-area) hands, the movements being converted into acoustic vibrations - in this case chords. In the mechanical instrument of this class, the key panel is stacked on the previous keys which, reduced to a minimum, become sensors for the novel key panel. The key sequence is retained. The key panel, used in the electronic music field, is characterised by the fact that the sensoric movements of the hands or the pulses triggered by them are scanned by electric sensors, i.e. music is switched with corresponding light signals, high tones are accompanied by bright light signals, deep tones are accompanied by dark light signals. The essential aspect is association and combination of sensitive and acoustic and visual impressions. <IMAGE>
