Abstract: Photo-optical keyboards for providing electrical signals responsive to the keying of the keyboard. The keyboard structure consists of an arrangement of individual keys disposed and identified in accordance with the particular application and adapted for longitudinal motion on depression thereof. Located below the plurality of keys is a matrix of light sources and photo detectors disposed in such a manner that depression of any single key will interrupt the light path between one of the light sources and one of the detectors to provide a change in the electrical state of the associated circuitry. The light sources and detectors are arranged so that in general a single light source illuminates a plurality of detectors, and each detector may be illuminated by any of a plurality of light sources, so that the number of light sources and sensors required for the complete keyboard is substantially less than the number of keys to be sensed. A microprocessor based system for scanning the light sources and detectors is disclosed. In general individual light channels in the keyboard structure are not required as a scanning technique avoids undesired optical cross-talk. By making a portion of each key substantially transparent, light from the light sources may be directed upward through the keys to illuminate the keyboard.

Abstract: A self-igniting thyristor has a zener diode integral with the thyristor, which zener diode bridges the central junction of the thyristor and the breakdown voltage of which determines the breakover voltage of the thyristor. The breakdown voltage of the zener diode is determined by the field geometry in that part of the PN junction of the zener diode which is located near the surface of the semiconductor body, where the breakdown is arranged to take place. A conducting screen is arranged over said portion of the PN junction of the zener diode and is separated from the underlying portion of the surface of the semiconductor body by an insulating layer. The thyristor is provided with means for influencing the potential of the screen, which in turn influences the field geometry and thus the breakdown voltage of the zener diode and the breakover voltage of the thyristor.

Abstract: The invention refers to a transmitting/receiving switch in PIN diode technology substantially intended for the frequency range of 1.5-30 megahertz and transmitter power up to 1200 watts. Included combinations of inductances and capacitances, which have the purpose of isolating high frequency signals from direct current supply circuits and which according to earlier known design methods would have been expensive and difficult to implement for the above-mentioned frequency and power range are chosen according to form high-pass filters. In this manner lower and more easily implementable values are achieved simultaneously with decreased time constants and thereby also faster switching times. The direct current supply circuits are provided with active circuits connected in such manner that no resistances which can increase the time constants in switching from transmitting to receiving and vice versa are disposed in series with the current supplies. The direct current biases are held constant and well-defined by current generators.

Abstract: The present invention relates to a lensless spectrum nalyser, preferably of integrated optical type, with a radiaon source (1) connected to a waveguide (2) which is onnected to an electro-optical deflector (3), exploiting Pockel's effect. The radiation from the deflector (3) is guided by the waveguide (2) on to a detection matrix (4). The electro-optical deflector (3) then consists of an electrode matrix (5) with the electrodes (6-11) arranged in or in the vicinity of an electro-optically active material (21). The electrodes (6-11) which are of different widths and are arranged at different distances from each other are arranged along a line (18) which is largely disposed at right angle to the incident radiation. By this means, the deflector acquires lens properties and can perform the desired Fourier transformation of the electric signal connected to the deflector (3). In the course of this transformation, the incident radiation is divided up into bundles of rays representing different Fourier components and focused along a focal line (20) along which the detection matrix (4) is arranged. Since the deflector possesses lens properties, it becomes possible to elaborate the entire device according to the invention in integrated form, enabling the device to be manufactured in its entirety by application of photolithographic technology.

Abstract: Ice lollies are frozen in two-parted moulds which are inserted in rows of freezing pockets in an ice lolly freezing machine. The moulds are thawed loose from the freezing pockets in which freezing has been carried out, are lifted out of the freezing pockets, separated for releasing the frozen ice lollies, assembled and inserted again into a row of freezing pockets. Before the moulds are lifted, a moderate heating of the freezing pockets is carried out sufficient for thawing loose the moulds with respect to the pockets. Then the moulds are lifted and moved to a position outside the area of such freezing pockets of such freezing machine. At the position the moulds are heated for thawing loose the ice lollies. Then the moulds are separated and the ice lollies removed while the moulds are positioned outside the area of the freezing pockets. Now the moulds are moved back to the area of the freezing pockets and are inserted into an empty row of freezing pockets. A corresponding picking-up device moves the lifted moulds in close condition to a position outside the area of the freezing pockets and at such position a thawing up medium is supplied to the outer surfaces of the moulds. The moulds are then moved back to the area of the freezing pockets.
