Title: Improvement in or relating to amusement devices
IPC: A63B69/00
Filed: 1949-12-01
Abstract: 693,746. Chance apparatus. CLEAVE, S. A. Nov. 16, 1950. [Dec. 1, 1949] No. 30901/49. Class 132 (ii). An amusement device comprises a hinged flap and a ball positioned in front of the flap, the whole being so arranged that when the ball is kicked against the flap, the flap is displaced in a manner actuating a free-wheel device causing movement of a pointer over a scale. As shown, the flap 9, Fig. 2, is pivoted on a horizontal axis and when struck by the ball 7 its resulting motion causes an upward movement of a vertical rod 17 shown more clearly in the rear elevation of the device in Fig. 4. The upward movement of the rod 17 is transferred by a pin 20 on the rod 17 to a chain 16 extending between two sprocket wheels 13, 15 the upper one of which is a free wheel. The resultant impulse to the chain sets the free wheel spinning whilst the rod 17 returns to its normal position. The spinning effect is indicated by a pointer 3 secured to the free wheel, the pointer 3 being backed by a dial. A goal may be represented on the dial and an electrically conductive strip 21 may extend between the posts of the goal. The pointer 3 may also be electrically conductive so that as it rotates it may contact the conductive strip once during each revolution and momentarily complete an electric circuit to a lamp or bell 23. Should the pointer stop between the goal posts, the continuous illumination of the lamp or ringing of the bell indicates a goal. An automatic coin-freed mechanism may be provided to which a coin must be inserted before the flap or the ball can be actuated. The Provisional Specification describes a modification in which instead of a pin 20 being fixed to the rod 17, the rod 17 carries a pawl engaging a ratchet carried by a sleeve or wheel mounted on the pointer spindle by a free wheel connection, so that as the rod 17 moves upwards the pawl engages in a ratchet ,and rotates the pointer spindle through the free wheel connection.

Title: Improvements in or relating to processes for the manufacture of magnesia containing refractory materials
Filed: 1946-10-17
Abstract: Magnesia-containing refractory material is made by sintering in a reducing atmosphere pure or impure magnesia which is not already fused or sintered.  A temperature of 1600 DEG  C. or lower, e.g. 1400-1500 DEG  C., may be used for nearly pure magnesia obtained from sea water, the temperature necessary for sintering being lower than if an oxidizing or neutral atmosphere is used.  A magnesia of 89 per cent purity may be sintered at 1300 DEG  C.  An electric oven with a graphite lining may be employed.  The reducing atmosphere may be obtained by burning fuel with a slight deficiency of air.ALSO:Magnesia-containing refractory material is made by sintering in a reducing atmosphere pure or impure magnesia which is not already fused or sintered.

Abstract: 197,973. Michell Bearings, Ltd., and Newbigin, H. T. Nov. 21, 1921. Thrust and end-pressure bearings.-The pads which take the thrust in a Michell bearing are so disposed circumferentially round the thrust collar that the centre of pressure in the padsupporting member falls below the centre of the shaft, in order that the cylinders and pistons of a dynamometer device may be located in the lower part of the thrust block. The support F for the bearing pads E is U-shaped, and is provided with a liner f<3> against which abut the ends of two cylinders G one on each side of the shaft. Rotation of the member F about the shaft is prevented by a crown piece Q. Each cylinder G fits over a piston head H fixed in the bosses formed in the lower part of the block. Normally the inside face of each cylinder bears against the piston head which takes the thrust. The shape of the pad-support F enables it to be turned through 180‹ and withdrawn with the pads without disturbing the shaft. Speeifica,- tion 104,375 is referred to.

Title: Semiconductor element and device and method of fabricating the same
IPC: H01L29/866
Filed: 1963-08-06
Abstract: 1,060,303. Semi-conductor devices. MOTOROLA Inc. Aug. 6, 1963 [March 18, 1963], No. 31031/63. Heading H1K. In a device comprising a P(N) zone formed as an inclusion in one surface of a zone or body of N(P) type the breakdown voltage of the intervening PN junction is increased by providing a lateral extension of the P(N) zone of higher resistivity on the surrounding surface which is terminated by a ring of N(P) type of higher conductivity than the N(P) zone or body. In a transistor of this type, Fig. 3, the N type base zone 15 has a higher resistivity surface extension 20 terminated by a ring 21 of heavily doped P material extending into the collector region proper 12. Such a device may be made from a P type silicon wafer by diffusing donor impurity through oxide masking to form the base zone proper, then similarly diffusing acceptor material in to form the emitter zone and ring 21 and epitaxially depositing lightly doped silicon on the cleaned surface to form the base zone extension, relying on back diffusion from the ring and emitter to extend these to the surface. Finally the surface is oxidized and contacts made to base and emitter zones through apertures in the oxide layer. As an alternative the base extension is formed after the base proper but before the emitter and ring, or the ring is formed right at the start. In another method the base extension is formed at the start by first diffusing donor impurities into the appropriate parts of the surface and then epitaxially depositing silicon over the upper surface. The donor impurity diffuses outwards into this but to give only a lightly doped surface layer. The base proper, emitter and ring are formed in subsequent diffusion steps. In a modification of this process an out-diffusion step replaces the epitaxial deposition. An NPN transistor may be made by forming first the base proper and then the emitter and ring by diffusion into an N type wafer and then exposing the surface, which is still oxide masked to gallium vapour, which diffuses through the oxide to form the base extension. In yet another method of making the PNP transistor the base extension is formed at the start as an inversion layer by oxidizing the surface of the P type wafer in an atmosphere of argon rich in water vapour, the remaining zones being formed by diffusion as before. The effective resistivity of the base extension may in this case be subsequently increased by etching to reduce the thickness of the oxide layer. The possibility of forming P type inversion layers by oxidation in pure oxygen is also envisaged. Protection against surface contamination is effected by mounting in metal cans in conventional manner.
