IPC: H01L35/12
Filed: 1962-11-05
Abstract: 1,042,594. Casting processes. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Oct. 21, 1963 [Nov. 5, 1962], No. 41765/62. Heading B3F. In a method of casting thin rods a mould member 1 (the Figure, not shown) is inserted through an opening 4 in the top of a vessel 2 containing molten material. The mould member 1 has an end portion 3 and an enlarged portion spaced axially therefrom so that when in the required position in the vessel, the end portion 3 lies just beneath the surface of the molten material and the enlarged portion co-operates with the opening 4 so as to seal the vessel. Pressure created in the vessel or a vacuum created in the mould member causes the molten material to rise into the end portion of the mould member where it is allowed to solidify and so form a thin rod which is subsequently removed from the mould member.

Abstract: 1407095 Strapping articles FMC CORP 11 Sept 1972 [15 Nov 1971] 42056/72 Heading B8C [Also in Division B5] Strapping apparatus has rollers 34, 36 to feed a polypropylene polyester or nylon strap around a yoke 20 to a stop 19 on an anvil 18, and a flag 70 to sense the formation of a loop of the strap at the roller 36 after the end of the strap has engaged the stop, the flag actuating a switch 72 to cause a gripper 30 to grip the strap end against the anvil and to reverse the rollers 34, 36 to remove the loop. Manual actuation of another switch causes further reverse driving of the rollers to pull the strap out of resiliently mounted plates (244, 245, Fig. 17, not shown) in the yoke and to tension it around an article. The reverse driving continues until the removal of stack in the chain driving roller 36 causes an idler sprocket to actuate a limit switch. The bight of the strap is then gripped between the anvil and a gripper 32 and a composite cam member (190, Fig. 6, not shown) is moved to cause a tongue 24 between the strap end and the bight to pivot away and to be replaced by a pivotal electrically heated blade. A platen 26 is also raised to cut the bight and, after removal of the blade, resiliently to press the strap ends together. The grippers 30, 32 are released and on reverse movement of the cam member the anvil is pivoted out of the way to release the joined strap. The apparatus is pneumatically operated.

Abstract: 931,597. Semi-conductor devices. SIEMENS & HALSKE A.G. Dec. 14, 1959 [Dec. 17, 1958], No. 42427/59. Class 37. A high positive temperature coefficient resistor comprises a ceramic of Perovskite structure including barium and titanium as major constituents and antimony as a doping material, the proportion of antimony being such as to produce a ratio of the maximum resistance to the resistance at the Curie temperature which is at least 90% of the highest magnitude obtainable by doping with antimony. Where the basic ceramic material is of the formula (Ba x Sr 1  -  x )TiO 3  the quantity of antimony required to produce a maximum value of the maximum resistance ratio varies with the value of x as shown in Fig. 2, although the maximum value itself is substantially independent of x. An exemplary material with a positive temperature coefficient of resistance over the range 0-100‹ C. is made by mixing antimony oxide, barium carbonate, strontium carbonate and titanium dioxide in the molecular proportions 0.005: 0.6: 0.4:1, 1, heating the mix at a rate of 300‹ C. per hour to 1000‹ C., maintaining at 1000‹ C. for 2 hours, and then cooling to 500‹ C. in 3 hours. The resulting product is ground to a fine powder which is pressed into shape and sintered in an oxidising atmosphere at 1360‹ C. for 10 minutes, and subsequently cooled.

A fuel element assembly for use in a boiling coolant reactor comprises a first flow path adapted for the generation of vapour through heat exchange between a surface of each of a group of nuclear fuel elements and liquid coolant, separating means arranged to receive vapour and liquid mixture from the first flow path and separate vapour from the liquid, and a second flow path arranged to receive vapour from the separating means and adapted for the superheating of vapour through heat exchange between another surface of each of said nuclear fuel elements and the vapour. In the boiling water reactor shown in Fig. 1 a number of fuel assemblies 26 are fitted at their lower ends into a support plate 22 and extend upwardly through the liquid space into a vapour space 18. Each assembly is provided with a conduit 30 communicating with the vapour space and extending through a scrubber 28, each conduit 30 carrying a deflector plate 32. The fuel assemblies are surrounded by three thermal shields 34, 36 and 38 provided with orifices 39 at their lower ends, and a ring-shaped inlet water header 40 also encircles the assemblies. A hemispherical insulated plate 42 is attached at its periphery to the support plate 22 to form a collection chamber 44 for superheated vapour connected to an outlet nozzle 46 extending through the lower thermal shield 24 and the bottom of the pressure vessel. Each fuel assembly 26 may be as shown in Fig. 3 and comprise a number of tubular fuel elements 52 extending between support blocks 54, 56, the lower face of the upper support block 54 being inclined upwardly from its centre to direct coolant impinging on it outwardly to its periphery. Water passes upwardly over the outsides of fuel elements 52 and into a cyclone separator 60 where steam is separated and water flows back through openings 78 and 80 to the water space. The steam passes out of the separator 60 through an outlet 67 on to a deflector plate 32 and then through scrubber 28 (Fig. 1) and vapour space 18 (Fig. 1) into tube 30; from the tube 30 the steam passes through the insides of tubular fuel elements 52 to the vapour space 44 (Fig. 1).
