Abstract: A device such as a sieve or feeder (1) is provided with two parallel shafts having respective out-of-balance weight means (5) comprising weights (10) located in casings, each shaft being driven by its own motor (3), preferably of asynchronous type. The out of balance weight means (5) are of different dimensions for each shaft and the centre of gravity of the device is so positioned that the ratio of the distances between the centre of gravity and the respective axes of rotation of the out of balance weight means, is inversely proportional to the products of the weights of the respective out of balance means and their mean distance to the respective axis of rotation so that an elliptical stroke can be obtained. The direction of stroke can be altered by changing the ratio of the values of power supplied to the two motors. <IMAGE>

Abstract: A structured copper strain buffer, which is thermally and electrically conductive is provided for use with semiconductor electronic devices. A thermo-compression diffusion bond is used to attach a metallic foil to a structured copper disk to form the strain buffer. The individual strands of copper within the strain buffer are capable of independent movement. The structured copper strain buffer provides a means of attachment to a semiconductor device without causing a stress to be generated at the attached surface of the device as the device expands and contracts with temperature changes.

Abstract: The information concerned is in the form of a light intensity and/or light polarisation and/or spectral composition varying in one, two or three dimensions and/or over time and the conversion of the information is performed by electrooptical modulators, which for example comprise liquid crystals, and photodetectors, such as for example photoresistors. According to the invention, the electrooptical modulators (1) consist of a material of intrinsic hysteresis with respect to the dependence of the light transmission on the modulator voltage. The modulators (1a, 1b...) are located in the path of rays between at least one light source and photodetectors (2a, 2b..), of which at least one is arranged behind each modulator (1), seen from the light source. Each modulator has on its one side an electrode which is isolated from the other modulator electrodes and determines the geometrical size of the modulator. Each photodetector (2) is electrically connected to the electrode (12) of a neighbouring modulator. In this way, many registers of simple construction are obtained. The shift registers are activated either electrically by means of voltage sources (4 and 5) or optically. <IMAGE>

Abstract: A rotating electrical machine having an oblique air gap between the stator and rotor, with an inclination angle  alpha  = 25 DEG -155 DEG or 205 DEG -355 DEG with respect to the rotation axis of the shaft of the rotor, makes possible a reduction in the magnetisation current and hence also an improvement in the machine utilisation factor. This is achieved by reducing the air gaps. The new design furthermore produces improvements with respect to shortening and reducing the size of the shaft diameter (material saving), reducing the cross-section of the electrical conductors while improving the cooling, reducing the insulation-voltage level, and improving the starting torque and the current. It furthermore raises the possibility of simplifying production of the pole cores. <IMAGE>

Abstract: The non-synchronous arrangement comprises an optical scanner which produces a video signal by scanning in a field with a row pattern comprising straight, equidistant, parallel lines over the object. Recording takes place at a field frequency equal or lower than the standard for television. The video signal is converted to a standard TV signal for presentation on a TV monitor of standard type. Two separate memories are used and a recorder unit cyclically and in sequence connects the video signal from the scanner to each of the memories for registration of picture information. A changeover from one memory to the other, i.e. from one being read out to one not being read out, occurs before each recording of new picture data. A readout device works in conjunction with the registration unit, and forms a standard TV signal as input to a TV monitor. (Provisional Basic advised week 85/04)

Abstract: A method of and apparatus for effecting rapid, reliable and risk-free, pressure-tight connection of a plasma generator to a reactor, such as a shaft furnace for metal oxide reduction. First electrical contact means arranged on a plasma generator, substantially enclosed by a cover, automatically connect the plasma generator to stationary second contact means when the plasma generator is moved by remote-control to a fully installed operating position from a partially installed sealing position in which the plasma generator has its front end partially inserted in the reactor tuyere and seals the reactor. A remote-controlled valve, which seals the reactor from the surroundings when the plasma generator is in an outer completely retracted position, is opened once the plasma generator is in its sealing position, after which the plasma generator is moved to its operating position. Remote-controlled locking bars are caused to press and lock the plasma generator to the reactor in order to effect pressure-tight connection, and at the same time the locking bars connect the plasma generator to the return conductor to the current source, thus providing extra security against the current circuit being connected before a pressure-tight seal has been achieved.
