Title: Superconducting power supplies
IPC: H01L39/10
Filed: 1975-08-22
Abstract: 1514486 Superconductive arrangments SCIENCE RESEARCH COUNCIL 22 Aug 1975 [22 Aug 1974] 36910/74 Heading H3X [Also in Division H2] A superconductor supplied from an alternating current source is periodically switched to the non- conducting state by a pulse of heat synchronized with the onset of each non-conducting half cycle to develop a resistive region, the heat pulse being produced by a pulse of current having a duration of less than one quarter of a cycle (e.g. 2 milliseconds for a frequency of 50 cycles per second) which is applied to each of a plurality of stainless steel or constantan heating foils 2, 4, 6 spaced across the parallel wires 8, 10, 12, 14 forming the superconductor. When switching to the non-conducting state is effected, the superconductor has a resistive region produced initially by the heat pulse which subsequently expands and then contracts along the length of the superconductor wires during the remainder of the half cycle. The arrangement may be applied to the flux pump described in Specification 1,513,153, the wires 8-14 being paired to form the oppositely wound superconductive windings.

Abstract: 1,151,115. Valves. A. SCHOEPE, and F. E. SCHMUCK. 1 June, 1967 [23 June, 1966], No. 36959/68. Divided out of 1,151,114. Heading F2V. A float valve 40, for maintaining constant the level of liquid in a container 24, comprises a housing having upper and lower parts 80 and 90, respectively, the former part having integrally formed therewith a rigid float guide 34 and the latter part being supported by a casing member 54 resting on the flange 46 of a generally conical inlet member 42, 48, 50, 52. The two parts of the housing are detachably secured together by a bayonet joint provided by forming on the housing lower portion 90 circumferentially spaced and inwardly projecting engagement flanges 160 which slidably engage and overlie circumferentially spaced outwardly projecting flanges 162 formed on the housing upper portion 80. The degree of relative rotation between the two housing portions is limited by a stop member 164. The guide is generally rectangular in cross-section and is formed with two opposite continuous sides 156, the remaining opposite sides 158 being formed with latticed-grooves therein. The float is disposed slidably but non- rotatably on the guide such that rotation of the float causes rotation of the guide and hence of the housing upper part and consequential disengagement of the two housing parts. Between the housing parts is disposed a diaphragm 82 composed of three interconnected concentric parts 100, 96, 92 of which only the central part 96 is movable towards and away from a seat 86 as a result of the presence or absence respectively of liquid in a chamber 108 formed between the diaphragm and housing upper part, such motion of the part regulating the flow of liquid between the inlet member and an outlet port 60 from which port liquid passes through channels in the casing 54 and finally through a slot 78 into the container. The quantity of fluid in the chamber 108 is regulated by a pin 84 which has sections of varying diameter, some of which are grooved, and is movable, to permit flow from the inlet to the chamber or from the chamber to an exhaust opening formed in the housing upper part, in dependence on the position of the float, the pin being connected to the float by links 38, 36. The nature of the pin and casing ensures that solid material is deposited in the casing, from which it can be subsequently removed upon separation of the housing parts, and that no such material enters chamber 108.

Title: Structural Balancing Game
IPC: A63F3/00
Filed: 1967-08-15
Abstract: 1,175,105. Balancing game. M. I. GLASS [trading as MARVIN GLASS & ASSOCIATES]. 15 Aug., 1967 [9 Feb., 1967], No. 37488/67. Heading A6H. A balancing game apparatus comprises a plurality of generally planar platform members 10, a plurality of supporting post members 14 adapted to be vertically positioned between the platform members to thereby provide a multilevel construction, and each of the platform members having raised portions 20 thereon providing limited access along the surface of the platform between the inner surface portion thereof and the side edges of the platform. As shown, the apparatus is constructed using posts 14 of various colours which are placed on circular markings 24 of the same colour with an alarm device 16 mounted on the top. The players achieve their score by removing posts 14 in accordance with instructions by a spinner device which indicates the colour of the post to be removed and the player may select a post of that colour from any level of the structure and must remove the post from the exit having an arrow or other marking, indicated at 50, of the same colour as the post. He may move, but not remove, other posts in order to move the selected post 14 away from the structure, and the player may also move the selected post to another level, through one of the openings 26, before finally withdrawing it from the structure through an exit of the same colour. The player may also sacrifice one of his previously acquired posts 14 in supporting the structure during the removal of a post. Each of the different colour posts has a different value, and the players final score is determined by the total value of posts acquired. During the play of the game, the upper platform 10 is frequently tilted and this causes the alarm 16 to sound and warn the player that he is in danger of toppling the entire structure. Points are acquired only by successfully removing posts 14 while maintaining the platform 10 in position and if a player collapses the structure he is automatically out of the game, and the remaining player having the most points is the winner.
