Patent EP-0002108-A1 (EP)
Inventor: KNIGHT PETER ALAN
IPC: C08J5/18
Filed: 1978-10-23
Abstract: A coloured acrylic sheet having an attractive 3-dimensional depth of colour resulting from the use of a mixture of pigments or a pigment and a dye wherein an inorganic pigment, distributed non-uniformly throughout the sheet and a colourant is distributed uniformly through the sheet, the particles of non-uniformly distributed pigment being concentrated preferentially towards one surface of the sheet and are visible through the opposite surface of the sheet which is preferably substantially free from the non-uniformly distributed pigment. The attractive appearance is further enhanced by shaping the sheet and the sheet is particularly suitable for forming articles of sanitaryware.

Abstract: There is disclosed an electrical drive motor, in particular for the water pumps in the field of aquaria, wherein the housing is universally sealed liquid- and gas-proof and wherein a permanent-magnetic coupling is located on the motor shaft acting through the sealed housing wall. In order to render this drive motor independent so that it may be used for various units, is able to be connected thereto with no problems and in addition thereto is reliable, the side of the motor housing directed toward the water pump is defined as a thin-walled diaphragm with a planar outer surface which is engagable with a likewise planar sealed diaphragm surface of the pump casing, in the area of the diaphragm securing means being provided for connecting the motor housing to the pump casing. Such a motor may be used with no problems in the field of aquaria and may even be used submerged in water.

Abstract: The bicycle of a light type comprises a frame (1) carried by two wheels (2, resp. 3). The rear wheel may be driven by handles (5) and, preferably, by a free wheel mechanism arranged into the hub (8) of the wheel. The bicycle is deprived of a train driving mechanism and of a construction between the front wheel (2) and the rear wheel (3). This arrangement allows a decrease of the effort exerted on the pedals (6) and a healthier position of the body of the user. The shaft which carries the handles (5) traverses the hub (8) of the rear wheel. It is connected therein by a transmission (17, resp. 47, resp. 50) presenting at least a gear change. Said shaft (7) is supported by two bearing (12, resp. 13) extending at each side of the hub (8). By means of this bearing, the rear wheel (3) is connected by a screw fixing device to the frame (1), independently of the shaft (7). The saddle (10) is positioned above the rear hub (8) and carried by a vertical bar (9) of the frame.

Abstract: Die Erfindung betrifft eine Anordnung zur forcierten Kühlung einer Magnetspulenwicklung mit Kühlmittelanschlußstellen zur Einspeisung und Ausleitung eines Kühlmittels in die bzw. aus der Wicklung, deren supraleitende Leiter durch Stromdichte I, Feldstärke H und Temperatur T festgelegte Arbeitspunkte haben, die von dem jeweils nächstliegenden Sprungpunkt des supraleitenden Materials verschieden weit entfernt sind. Bei diesen bekannten Kühlanordnungen wird jedoch eine Ausbreitung einer von einem kritischen Leiterbereich ausgehenden normalleitenden Zone durch das Kühlmittel noch unterstützt, da bisher das Kühlmittel immer an diesem kritischen Leiterbereich in die Wicklung eingespeist wurde. Die Erfindung sieht deshalb vor, daß en der Kühlmittelanschlußstelle (24) mit der geringsten Entfernung zu dem Leiterbereich (14) der Wicklung (2), dessen Arbeitspunkt einem Sprungpunkt am nächsten liegt, eine Ausleitung des Kühlmittels (A) aus der Wicklung (2) vorgesehen ist. Die Supraleister können insbesondere als Hohlleiter gestaltet sein. Derartige Kühlanordnungen können insbesondere für supraleitende Großmagnete mit beispielsweise D-förmiger Gestalt vorgesehen werden.

Abstract: A field controlled thyristor having its base (30,31) doped more lightly near the gate (41) than near the anode (32) achieves a low forward voltage drop, high blocking gain, and fast switching speed at any given forward blocking voltage rating. Although the high resistivity region (30) around the gate area allows the device to pinch off anode current flow at zero gate bias due to the gate junction inherent potential, a small forward gate voltage can trigger the device into conduction. The high resistivity of the channel area between gates provides DC blocking gains greater than 60. The device can be fabricated using conventional planar processing techniques.
