The method of making the rail comprises casting a cylindrical or polygonal section ingot 22 of tread alloy, allowing it to cool, casting an annular ingot 24 of adjoining portion alloy around the ingot 22, and allowing it to cool. Alternatively the two ingots may be continuously cast together. The billet 20 formed by the double ingot is preheated and is elevated with a dummy block 36 by mechanism (not shown), into alignment with an electrically heated container 30 in the extrusion press, and a ram 34 moves the billet 20 and block 36 into the container 30 and crushes them against the die 32. The interface 23 between the ingots 22, 24 is presented to three or four die openings 38 and the three extruded rails formed are pressquenched. Alternatively the rails are heated and quenched subsequently. When the ingot 22 is polygonal in section, it is rotated prior to each extrusion to orient the sides with the die openings.

Class 40 (6) In a circuit of the "bootstrap" type in which a capacitor is charged over a resistor, part at least is connected in series with a rectifier which is biased to a non-conducting state over part of the sweep. Capacitor 1, Fig. 1, normally held discharged by valve 12 conducting, charges when a negative pulse cuts off valve 12, the resulting rise in potential being fed out through cathode follower 6 which also feeds back over coupling capacitor 8. Diode 17 is held cut-off whilst valve 18 conducts but upon a negative auxiliary pulse being applied to valve 18 during the sweep, resistor 16 is connected effectively in parallel with resistor 2 due to diode 17 conducting. In a modification, Fig. 2, the main sweep pulse is fed to the suppressor grid and the auxiliary pulse to the control grid of a pentode 24, resistor 16 being connected to the screen grid. In a further modification, Fig. 3 (not shown), in which the sweep rate is decreased during the auxiliary pulse, the resistor 2 is omitted and the valve 18 is arranged to be normally non-conducting and fed with a postive auxiliary pulse to render it conducting.

Title: Improvements in and relating to sewing machines

Abstract: 852,616. Sewing machines, sewing. UNION SPECIAL MACHINE CO. Feb. 5, 1959 [Feb. 7, 1958], No. 4042/59. Class 112 Multi-needle machines, stitch-forming devices, stitched seams. A sewing machine comprises a pair of reciprocating needles disposed one behind the other in the direction of work feed, work feeding means adapted to advance the work by increments each equal to twice the distance between the needles, a threaded looper mounted to swing in the feed direction for co-operation with both needles, and spreader mechanism for co-operating with the looper. The multi-needle machine described in Specification 709,545 and adapted to produce parallel lines of double-loop stitching of the Federal 401 type, is modified by replacing one or more of the needles with a pair or pairs of needles spaced in the direction of work feed, and by adjusting the feed stroke to twice said spacing. The needles 23a, 23b carry threads 67, 68 respectively, and the looper 41a carries a thread 69. In Fig. 10 the looper, bearing a pair of needle thread loops seized on the previous descent of the needles, is moving rearwardly, and the loop of thread 69 extending from the looper to the work is held open by the laterally moving spreader 56a for the descent therethrough of the needles. In Fig. 17 the looper has shed the previously seized loops and the needles are about to ascend, the looptaker having moved to the inoperative position. In Fig. 18 the looper has moved forwardly into the loops formed by the, ascending needles, and the previously formed stitches are being set. The machine produces a modified form of Federal Type 402 stitch, as shown in Fig. 16, the stitch length being equal to half the feed stroke. The machine can produce one or more seams of said stitches. In addition, one or more seams can be produced with only one needle to form Type 401 stitches of stitch length equal to the feed stroke. The machine may be provided with an auxiliary roller feed as described in Specification 709,545, or with a needle feed as described in Specification 687,812. In a preferred form of looper arrangement, as shown in Figs. 23 and 25, the looper 100 has a vertical stem 101 received in an aperture formed in a holder 99 and locked in adjusted position therein by a set screw 102. A needle guard 103 is mounted on top of the holder, has a hole through which the stem 101 passes, and is locked in adjusted angular position by a set screw 104. The holder is formed integrally with a needle deflector 105.

Title: Improvements in or relating to semi-conductor devices
IPC: H01L31/16
Filed: 1962-02-02
Abstract: <PICT:0943316/C3/1> An electro-luminescent element 10 employed in combination with a photo-conductive body 10 has a pn or pin structure and is provided with radiationless recombination centres of a large capture cross-section so that these centres saturate at low current values, higher current values producing radiative recombinations such that the radiation increases according to the nth power of current, n being greatly in excess of unity.  For the embodiment described, n is twenty.  As shown, the element 10 is gallium phosphide having excess phosphorous in a P region 12 and excess gallium in a N region 13. Copper conductors 15, 17 attached by indium gallium solder, emerge from a base 2 of Bakelite covered with an aluminium cap 1.  The element 10 lies on a glass dome 8 beneath which photo-conductive body 3 is potted in epoxy resin 9. The body 3 is a disc of moulded and sintered cadmium sulphide containing 10-4 atoms of copper for each CdS molecule and an equal concentration of gallium.  The top surface of the disc has intermeshing comb-shaped gold electrodes. Copper conductors 4 and 6 are connected by means of silver paste.  The gallium phosphide element 10 contains impurities of iron and zinc and is produced as follows. Separate limbs of a quartz tube contain 10 gms. of gallium contaminated with iron and 3 gms. of phosphorus, respectively.  The gallium is heated to 1220 DEG  C. and the phosphorus to 430 DEG  C. and after slow cooling GaP crystals are formed in a Ga phase.  The phosphorus remaining is removed from its limb and replaced by 200 mgs. of zinc.  The limb containing Ga and GaP is now heated to 1220 DEG  C. for 30 mins. while the Zn is heated to 500 DEG  C. so that a certain proportion of Zn can dissolve in the melt of Ga and P. After cooling, the product is washed at 100 DEG  C. in dilute HCl to isolate the segregated crystals of GaP through which a search is conducted to find crystals having yn junctions. Impurities are present to the extent of 1016 atoms of iron and 2.1016 atoms of zinc/c.c. of GaP. Germanium, aluminium phosphide, or silicon carbide, may be used in place of gallium phosphide. The arrangement may be used as a modulator of current through the photo-conductor as shown, or, given feedback to the electroluminescent element, as a bi-stable element, and may be modified as a radiation intensifier or bi-stable element.
