Abstract: 1,039,915. Semi-conductor devices. STANDARD TELEPHONES & CABLES Ltd. May 21, 1965 [May 25, 1964], No. 21566/64. Heading H1K. A semi-conductor device having the structure shown in Fig. 3 constitutes a thyristor in which current between the terminal electrodes is controlled by the electrode connected to the P region between the junctions 1 and 2, the flow of current between the junctions 2 and 3 being divided between the paths 7 and 8. Fig. 3 is purely diagrammatic; the invention is concerned with a method of making such a structure in which, having formed the N region 9, e.g. by epitaxial deposition, on an N+ substrate providing the region 10, the junctions 2 and 3 are diffused into the free surface of region 9 and junction 1 is then diffused into the P region bounded by junction 2, so that the end product is a planar device (Fig. 4, not shown). In Fig. 5 (not shown) a third P region has been diffused into the surface of the region 9 between the terminal P regions, to provide a second control electrode which functions by field effect. This third region is isolated from the P region bounded by the junctions 2 and 3, but may surround the latter of these regions (Fig. 6, not shown). Exposed junction edges are protected by silicon dioxide, and the junction 1 may be locally short-circuited (at 16, Fig. 6) to prevent spurious triggering by " spikes " on the input voltage. The device is made of boron- and phosphorusdoped silicon; the use of an intermetallic compound semi-conductor is also mentioned.

W., Aug. 12, 1947, No. 22332- [Class 132 (ii)] [Also in Group XVIII] In a coin-freed amusement apparatus, a hollow steel ball 9, normally lying at the bottom of a forward compartment of a casing 8, is under the influence of an electromagnet 15 behind a partition 8c ; insertion of a coin energizes the magnet which is then traversed over the partition by manipulation of a handle 21a in an endeavour to convey the ball past hazards 11 to a basket 10. In Fig. I the electromagnet 15 is carried at the upper end of a lazy-tongs 20 mounted on an operating spindle 21 carried in a swivel bearing 22. Cables 23 connected to the outer ends of the two lowermost links of the lazy-tongs are wound about and secured to the operating spindle so that, by turning the spindle by means of its handle 21a, the lazy-tongs is extended against return springs 24 to raise the electromagnet 15 and ball 9, whilst rocking the operating spindle sideways in its bearing 22 enables the magnet to be moved sideways to negotiate the ball past the hazards and into the basket 10. In Fig. 2 the lazy-tongs is mounted to rock on a fixed pivot 28 passing through the cross-over point of the lowermost links. The operating spindle with its handle 21a, projects forwardly and is journalled in a bearing block mounted .to rock on the pivot 28. A pinion on the spindle engages arcuate racks 20d, 20f secured to the lowermost links of the lazy-tongs which can therefore be extended by turning the handle 21a and traversed laterally by rocking the handle about the pivot 28 of the spindle bearing block. In both constructions the hazards 11 are discs of flattened dome-like formation and are separated by gaps 13, just sufficient to allow the ball to be passed between an adjacent pair. The apparatus may incorporate a plurality of balls and electromagnets mounted for movement as described, in order to permit simultaneous operation by several players.

Abstract: 930,344. Ships' navigation lighting. A. VREUGDENHIL. June 21, 1961 [June 21, 1960], No. 22408/61. Class 118. The direction in which a ship turns is indicated by an arrow comprised by illuminating a pattern of electric lamps contained in downwardly pointed conical covers 4. By having conical-shaped covers the appearance of illumination produced by reflection from the covers is avoided since they will not reflect light from the horizon and above into the horizontal. By pointing the covers downwardly they are made to throw out light all round so as to be visible from all quarters. Two double-headed arrow arrays are preferably arranged one on each side and above a ship's bridge, the shaft and one head of each arrow being illuminated by throwing a two-pole switch to indicate a turn. The intensity of illumination is controlled to cope with varying conditions. The bridge has pilot indicators to show the state of the signal.
