Title: Thermal flow speed measurement - using combined heater-sensing elements at two measurement points independent of heating times
Inventor: MAGORI VALENTIN DIPL PHYS
IPC: G01P5/18
Filed: 1979-08-27
Abstract: A thermal flow measurement device is esp. for measuring flow speeds below 2 m/sec. A heater periodically heats the medium passing the beginning of a measurement path which then heats a temp. sensor at the end of the path. The time phase difference between the heating processes at both ends is measured. The measured phase difference and hence flow speed are practically unaffected by the heating times. These are speed and sensor material dependent. Each end of the measurement section (1) is defined by a measurement element (3,7) which is simultaneously a heating and temp. sensing device of thermally conducting material. These may consists of thick film heater elements with thermally coupled pyrodetectors mounted on a polarised ferroelectric foil.

Title: Engine suspension and method for suspending an engine on a chassis
Inventor: FUKUSHIMA MASAO
IPC: F16F7/108
Filed: 1981-02-26
Abstract: A damper rod of an engine mounting is designed in such a way that it forms two suspended masses, which are interconnected by elastomer devices, so that the rod has two resonance frequencies. The resonance frequencies are selected in such a way that they detect the vibration range in which resonance noises can occur in the passenger compartment, so that a first phase shift of the vibrations passing through the damper rod produces an interference with the vibration passing through the main mounting of the engine, in order to make the engine mounting softer overall and to absorb vibrations, which would otherwise lead to resonance noises in the passenger compartment. The effect of the second resonance overlaps with the first resonance in order to expand the softer behaviour of the engine mounting until the second phase shift has occurred. <IMAGE>

IPC: D06C23/02
Filed: 1981-05-02
Abstract: Parts are removed from the pile on the surface of the carpet used as initial material, in such a way that the desired patterning is formed by a differing pile height. Carpets consisting of natural resin fibres, especially coconut or sisal fibres, are processed for preference. The removal of the pile parts takes place expediently by means of conventional woodworking machines, especially shaping or milling machines. The method allows patterning in any form, arrangement and orientation of the patterning points at an adjustable, constant or varying cutting height.
Patent DE-3118458-A1 (DE)
Inventor: JUERGENSEN HEINRICH
IPC: H04N1/028
Filed: 1981-05-09
Abstract: A light pick-up device for transparency and/or opaque scanning in either a drum or flat bed scanning device consists of a hollow body, which exhibits a light entry opening for the modulated light coming from the master. The inside surface of the hollow body, which is designed as a light pick-up surface for the opto-electronic conversion of the scanning light into an image signal, consists of a multitude of sub-surfaces, whose surface normals are oriented in the direction of the incoming scanning light. The sub-surfaces are the light surfaces of either opto-electronic transducers or are the end faces of optical fibers whose other end faces are coupled to an opto-electronic transducer. Because the disruptive influence of scratches and shadow edges in the master is suppressed, a high efficiency and a good uniformity of the scanning are achieved with the light pick-up device.
