Title: Optical sensor detecting specific substances in material
Inventor: TIEFENTHALER KURT
IPC: G01N33/543
Filed: 1985-05-29
Abstract: Optical sensor for the detection of specific substances and refraction index alterations in gaseous, liquid, solid or porus materials to be tested- is designed with integrated optical elements. It consists of a wave conducting film (1) proivded with a diffraction screen (4) acting as a grid coupling or Bragg reflector applied on a substrate (2). In certain cases for the selective detection of specific substances in a material (3) under test, the grid region at least is covered with a selective chemisorption layer, whereby the material under test is applied at least in the region of the grid, either directly on the wave conducting film (1) or on the selective chemisorption auxiliary layer (5).  By chemisorption of a substance to be detected and contained in the material under test, a further layer (6) is deposited on the wave conducting film.  The sensor works on the basis that the chemisorption of a further layer (6) and/or a refractive index alteration of the material (3) under test, produces an alteration of the effective refractive index (N) of a light wave conveyed in the wave conductin film (1).  The optical arrangemnt (1-5) defects this alteration.

Title: Integrated frequency dividing cct. - has two Exclusive-OR gates cross coupled to give output when all four inputs are identical
IPC: H03K3/037
Filed: 1972-10-19
Abstract: The integrated frequency divider for clock pulses consists of two cross coupled Exclusive-OR gates (10, 12), or two Exclusive-NOR gates, each constructed from metalozide-silicon transistors. Each gate has one input cross coupled to the other gate output, and its second input connected to a common input (14), to which the clock pulse is applied. The divided pulses appear at the gates two outputs (16, 18). When the pulse signals on all four inputs (X1, X2, Y1, Y2) have the same binary value, the output gives a first binary state, while when all the input pulse signals do not have the same value, the output gives a second binary stage. The advantage of the divider circuit lies in its compactness.

Patent CH-659854-A5 (CH)
Inventor: HORVATH ATTILA JANOS TIBOR DR-
IPC: F02B27/02
Filed: 1980-11-21
Abstract: The supercharging method by intake oscillation in piston engine is based on a symetric and pneumatic resonance oscillation of the suction circuit (fig. 7), wherein gas masses (2, 4) determine essentially the proper vibration of the oscillating system with a plurality of masses (fig. 4) comprised of the suction circuit, oscillating symetrically. In a supercharged engine with turbo blower, the symetric resonance oscillation which is the most efficient at low engine speed is generated both by the cylinder group during its suction stroke and by the oscillating flow of the turbo blower (5). Despite of the oscillating flow which is amplified by the rotor of the blower, the compression flow is not exposed to the so feared pumping, because the suction circuit is so arranged that the undimensioned Horvath number, which clearly defines the behaviour of the compression flow of the turbo blower in an unstationnary operation, is not higher than one.

Title: Anti-blocking device for juice drainage channels - in horizontal wine press
IPC: B30B9/02
Filed: 1971-09-29
Granted: 1972-06-02
Abstract: The device is generally placed under the press and serves for the evacuation of the juice to an Archimedean screw. Two fine-meshed wire cloth screens are located between the press and the evacuation gutter; these can be opened and closes so that the juice alone flows into the gutter, to the exclusion of any other matter in the grapes. The pips, pulp and marc are only liberated for evacuation by the screw at the end of the pressing process, when the juice will already have been evacuated from the gutter. Loss of juice is thus avoided as the marc, when evacuated, will contain only a very small quantity of juice. The screens are brought together and sepd. again by the action of right- and left-handed screws driven by an electric motor.
