Title: Metallic cords and method and apparatus for making them
Inventor: CURTIS GEOFFREY
IPC: B21F7/00
Filed: 1964-06-02
Abstract: 1,101,718. Wire cord. STEEL CORDS Ltd. 1 June, 1965 [2 June, 1964], No. 22727/64. Addition to 1,017,073. Heading D1T. A method of manufacturing a wire cord comprises leading the wires of two or more wire groups, each of a number of wires between two and six inclusive wound with winding twist on a single bobbin, from their bobbins through a twisting device which forms them into a cord, and then leading the cord to a take-up device. By "winding with winding twist" is meant winding a group of wires over the end end of a bobbin whilst the main parts of the wires of the group are restrained from rotation, so that the group is twisted as each turn is made around the bobbin. In an apparatus Fig. 1 for carrying out the method, the wires on each bobbin 2 are unwound overend of the bobbin by means of a flyer 4, are temporarily separated by guide pins 6, passed through holes in a stationary lay plate 8, and thence through a die 9 to a lay pulley 10 in a cradle 11 that rotates about the axis of the lay plate to twist the wires together. The twisted wires then pass through a false twister 13 to temporarily increase the amount of twist of the wires in a manner straining them and producing a "dead" cord. The dead cord finally passes through an eye 14 rotating at the speed of the cradle 11 and thence via a pair of bell-shaped fliers 15 to a take up drum. The lay plate 8 may be in the form of an apertured disc, Fig. 3 (not shown) having slits extending from its periphery to each aperture to facilitate threading. Alteratively the lay plate 8 may be replaced by a plurality of pulleys held in a desired array by a frame Fig. 4 (not shown), there being one pulley for each wire.

Abstract: 879,096. Feedwater control of steam generators. SULZER FRERES S. A. June 29, 1960 [July 17, 1959], No. 22809/60. Class 123(2) In a forced-flow steam generating and heating plant, wherein feed water is forced by a pump E successively through an evaporating section I and superheating sections II, III in counterflow to a regulatable flow of nuclear reactor coolant having constant input and output temperatures, above and below a predetermined partial load the feed water is supplied respectively at a rate corresponding to, and greater than, that at which steam is led off the surplus water at the lower loads being separated at 2 and returned through a control valve 7 and a line 8 to the pump E for recirculation. In order to set the desired value to be maintained by a feedwater regulating circuit, including a restrictor 1, a pressure drop signal transmitter 13, a regulator 14, and a speed adjusting device 141 for the pump E, the regulator 14 is influenced by a signal derived by a pick-off 4 and transmited by a unit 16 and a control unit 15 and also by the pressure drop in a restrictor 3 which is signalled by a unit 17 through a regulator 18 to combine with the signal from the unit 15 in a summation unit 19. The combined signal then passes to the regulator 14 by way of a limiting unit 20 which sets a lower limit to the rate of feed-water flow so that the flow remains constant if the load drops below the predetermined partial load. Water is fed by means of a pipe 10 to an injection point 5 through a valve 9 which is controlled by a temperature pick-off 6 signals from which are transmitted at 11 to a regulator 12 connected to the valve 9 which is also provided with a signal transmitter 21 to transmit signals, according to the position of the valve 9, through an interrupter 22 and an integral regulator 23 to the unit 15 in order to correct the temperature at the point 4 slowly. The interrupter 22 is connected with the limiting unit 20 to break the connection between the units 21, 23 when the limiting unit 20 comes into action. The regulators 12, 15, 23 and the limiting unit 20 can be adjusted in relation to the load by means of signal lines 24, 26, 25, 27. The liquid separator 2 is provided with a blowdown pipe 29.

Abstract: 1,237,800. Making valve stem inserts; forging. J. F. SCHERER. 5 May, 1969, No. 22873/69. Headings B3A and B3H. [Also in Division F2] A method of making a pneumatic valve stem insert from a cylindrical metal tube 7 of uniform wall thickness comprises, compressing the tube axially to form a peripheral flange 12 intermediate the tube ends, radially expanding a first section 55 of the tube located between the flange and one end of the tube, radially expanding a second section 65 of the tube to form an internal taper 13, which is at least partially located between the flange and the other end of the tube, and threading the first section both internally and externally. The flange 12 is formed by locating the tube 7, which may be of brass, between a pair of male punches 50, 51 each of which is surrounded by steel sleeves 52, 53 and as the flange is formed the section 55 is axially compressed to increase the wall thickness. The punch 50 is replaced by a similar punch but of larger diameter further to enlarge the diameter of the section 55 and to increase its wall thickness. The section 65 is then bulged by a male die prior to expanding the diameter of the upper portion 70 of the section 55 while simultaneously rough forming the tapered valve seat section 13 by means of a male die 71. The die 71 is replaced by a die (78) which forms the taper to its final size, Fig. 13 (not shown). The end of the section 65 is crimped to form a section 16 either by a pair of semi-cylindrical discs (80) being moved into engagement therewith Fig. 12 (not shown) or by a female die forming a tapered or cylindrical small end section. Alternatively an interior rib may be formed by a pair of thin semi-cylindrical discs, Figs. 17, 18 (not shown). All the forming operations are carried out as rapidly as possible so that the metal will be heated continuously as it is worked and not allowed to cool between work steps. After forming, the internal and external threads 32, 40 are cut so that they are not co-extensive. Finally a rubber sleeve 6 is moulded around the insert.

[Class 44] [Also in Group X] Means for suspending a T-section lath d, used to support building boards from a purlin f, comprises a hanger e and a gapped rigid ring a which is inserted through a hole e in the web of the lath, turned to the position shown in Fig. 2, and then hooked over the upturned portion e<1> of the hanger e. In a modification shown in Fig. 6 a gapped rigid ring a is used to connect a fish-plate g to a lath d, the ring a being inserted through coinciding holes h in the fish-plate and the lath and turned to a locking position. This arrangement may be used to support as shown the lath d on the flange of an angle lath i or to connect two adjacent laths d end to end by using two rings a. The fish-plate may be of inverted U-section to fit over the web of the lath. In a further modification the holes in the fish-plate are slightly offset to those in the lath and a ring of rectangular cross-section is employed, a binding effect being thus produced when the ring is turned to a locking position. With this arrangement, as shown in Fig. 10, when a plain fish-plate is used an additional binding effect may be obtained by forcing the fish-plate k against the web of the lath d.
