Title: Improvements in or relating to electric resistance elements and process of manufacturing same
IPC: H05B3/50
Filed: 1938-12-16
Abstract: 510,221. Wire and ribbon resistances ; casting composite articles. MANUFACTURE GENERALE METALLURGIQUE. Dec. 16, 1938, Nos. 36715 and 36716. Convention dates, Dec. 20, 1937, and Dec. 1, 1938. [Class 37] [Also in Groups XI and XXII] A resistance element comprises a tubular sheath of cast metal clamped by the contraction of the metal around an insulated resistance member surrounding the supporting centre piece, and having gills partly embedded in the metal. A central tube 1, Figs. 1 and 1a, has staggered slits 2 formed in it to compensate for its longitudinal expansion. A resistance member 3 is wound on the centre piece 1 between layers 4, 5, of wound mica sheets and is enclosed by a tubular sheath 6 of cast metal carrying heat-radiating gills 7. Rings 10, 11, forming terminal connections are also cast and are held in position by contraction of the metal, the ring 10 making contact with the end of the resistance 3 and the ring 11 with the centre tube 1. At the other end the sheath 6 surrounds an insulating plug 13 at the end of the tube 1, which is connected to the end 14 of the resistance 3 so as to form a return conductor. An insulating sleeve 12 is located between the sheath 6 and the ring 10. The central holes of the gills 7 are notched or serrated so as to allow molten metal to flow past them when casting the sheath 6. The gills are separated by intermediate rings, which may be integral with the gills. As shown in Fig. 4 each gill 7 has around its hole a boss 23 formed by stamping. Each boss has a portion 24 of smaller diameter and terminates in an inwardly projecting flange 25 having four notches cut in it. The stepped portion 24 is fluted at 27 and fits into the boss 23 of the next gill. Bosses of different shapes may be employed, or the gills may be spaced by separate rings. The desired number of gills are fitted together and the central tube 1 wound with the resistance 3 is inserted through the central holes. The assembly is supported at both ends by mould heads 33, 34, Fig. 5, and clamped between cheeks 37, 38, by bolts 36 and springs 35. Each head 33, 34 is in two or more parts and the head 33 has a hole 39 through which the metal to form the tubular sheath 6 is cast. The metal flows along the core through the notches in the flanges 25, air escaping through the flutings 27, thereby preventing the formation of blisters.

Filed: 1972-08-03
Abstract: 1383424 Foundry moulding machine S LARKIN 3 Aug 1972 36366/72 Heading B3F A foundry moulding machine for forming two parallel rows of "flaskless" sand moulds has a moving bed 20 upon which are mounted four hinged walls 40, 41, 42, 43 forming two moulding chambers. At a moulding station 39 a toggle mechanism lowers a cover plate 50 upon the walls 40, 41 to clamp them in grooves 78. A pair of patterns 86 (Fig. 5) are introduced into opposite ends of the so-formed moulding chamber 40, 41,50 and the chamber is filled with sand through a hole 51. The patterns 86 are moved towards one another to compress a sand mould formed in the chamber 40, 41, 50 and, after withdrawal of the patterns 86 and cover-plate 50, the walls 40, 41 are moved away from the sand mould by springs 47, 48. The bed 20 slides rightwards to present the formed mould to an extracting device 96 at one side of the moulding station 39. While the mould is extracted from walls 40, 41 a further mould is formed in the walls 42, 43, which have been moved into the moulding station 39. The bed 20 then moves leftwards to present the second mould in walls 42, 43 to a second extracting device 96 on the other side of the moulding station 39 and the walls 40, 41 return to the moulding station 39 for the production of another mould. In this way, by reciprocating the bed 20, two lines of moulds are built up opposite the extracting devices 96. The extracting device (Fig. 9) comprises a box 102, of approximately the same cross-section of the moulds formed. A rubber ring 106 extends around its periphery and is brought into contact with a mould in a moulding chamber by a ram 98. Pressure air is then admitted to the box 102 through a port 110 during forward ejection movement of the box 102 to distribute pressure equally over the mould surface and avoid deformation. A pattern shuttle (not shown) is provided which lifts and lowers pairs of patterns into and out of the moulding station 39.

Title: Improvements in or relating to the coiling of strand material
Inventor: NYSTROM AXEL CONRAD
IPC: B65H54/82
Filed: 1969-07-22
Abstract: 1,254,479. Coiling strand material. WESTERN ELECTRIC CO. Inc. 22 July, 1969 [24 July, 1968], No. 36718/69. Heading D1T. An apparatus for coiling strand material, and of the kind in which the strand 20 is first coiled around a strand-engaging surface 60 such that as each fresh turn is wound onto the surface 60 the lowermost turn on the surface 60 disengages therefrom in coiled form, is characterized in that there is means 68 for applying a force that substantially completely circumscribes said surface to urge the strand material against the surface 60 prior to its becoming disengaged. As shown in the drawing the means 68 is a coiled tension spring. The spring 68 rests on a stationary plate 70 in a housing 72. As the convolutions 62 progress downwardly over the surface 58, the convolutions urge the spring 68 to rotate about its circumferential axis and progress also around the surface 60. This reduces wear on the spring 68. The strand 20 is laid onto the surface 60 by a roller 64 carried by a rotating plate 34 driven by a belt 32.  A plurality of rods 76-76 extend downwardly from the drum-type capstan 60 and cooperate with levers 78-78 which swing inwardly into engagement with the rods to form an accumulator system when one of the takeup devices (not shown) is changed. A tapered guide 80 helps to constrain the portions of the wire 20 as they fall to the takeup. The means 68 may be a band of elastomeric material, or a series of contiguous rollers held together resiliently by a spring or rubber band. The strand engaging surface 60 may be stationary or moving.

Abstract: 1438569 Seed planting MASSEY-FERGUSON INC 2 Aug 1973 [14 Aug 1972] 36721/73 Heading AID Each row unit, of a multi-row seed planter is adapted to decelerate seeds arriving from a common seed dispenser D through a hose 21, for subsequent delivery to the exit chute member 73 by engagement of the seed with a pair of feed members of which one or both is driven, so that seeds are slowed by engaging the feed members to the speed of the driven feed member. The moving member may be a wheel 45, the periphery of the wheel being an annular member 47 of foam material, with the flexible member 47 riding in a trough 67, the space between the trough 67 and the member 47 being less than the thickness of the seeds to be deposited. The seeds, travelling at a high velocity in the hose 21, are slowed to the peripheral speed of the wheel 45 (which depends on the speed of the planter) when they pass through the space between the trough 67 and the flexible member 47, the flexible member 47 being compressed by the seeds. The speed reducing wheel may be driven from the press-wheel 15, or by an electric, hydraulic, or air driven motor. The trough 67 may be replaced by an idler wheel. Alternatively, a moving conveying belt may be used to decelerate the seeds.

Title: A contact field arrangement in an automatic telephone or telegraph exchange

IPC: H01H67/26
Filed: 1959-10-30
Abstract: 885,609. Automatic exchange systems. TESLA, NARODNI PODNIK. Oct. 30, 1959, No. 36907/59. Class 40 (4). In a two - stage cross - bar switching system incoming lines are fed to the first stage over a split and staggered multiple. As shown in Fig. 2, 100 incoming lines 00 . . . 99 are given access to 30 inter-stage links 1 . . . 30 (leading to a second stage switch) over three cross-bar switches I, II, III assembled effectively as one large switch. It is seen that a pair of incoming lines, say 02, 12 have access to links 3 . . . 8 whereas lines 03, 13 have access to links 4 . . . 9 and so on. The arrangement gives flexibility without giving up the advantages of bare-wire multipling. Chain arrangements, Fig. 3, are described for selecting a link when an incoming line is marked (either calling or called). The marking, say of line 03, involves the operation of a horizontal magnet 3H A  and the operation of a D relay (say 1D) indicative of a group of twenty lines. The D relays are chain connected so that only one can operate at a time. The H A  magnets are similarly connected. It will be noted that the two 3ha contacts isolate a portion of the chain corresponding to links 4 . . . 9 and with 1D operated circuits are made for the horizontal magnets 3H B  . . . 8H B  of the second stage switch. These magnets are associated one for one with the vertical magnets 4V A  . . . 9V A  of the first stage switch. The operated state of a V A  contact indicates that the associated link is busy and disables the corresponding horizontal magnet H B  of the second stage switch. Selection of a link is then effected by the operation of the quickest acting H B  magnet in the isolated portion of the chain. An alarm circuit comprises a relay PRI whose differentially wound windings are normally operated over the hb contact chain and the d contact chain, so that failure of one of the contacts unbalances the relay to cause it to operate. The ha contact chain is also tested by relay PRII whose release brings up an alarm. PRII is prevented from releasing by a contact n when the chain is in use. Arrangements are also shown for increasing the number of link circuits, by providing an additional cross-bar switch providing two extra links for each subscriber, the modifications for the chain circuit being indicated.
