Title: Improvements in or relating to a transitional coupling device
IPC: B61G5/04
Filed: 1960-01-22
Abstract: 925,221. Transitional couplings; combined buffer and draw gear. NATIONAL CASTINGS CO. Jan. 22, 1960 [Jan. 23, 1959], No. 2428/60. Class 103(5). A railway vehicle having an end sill 8a, side buffers, and a draw hook 4a, Figs. 1, 2, is provided with an automatic coupler head which is pivoted to the draw hook and provided at each side with a spring urged thrust element 51, 52 which abuts against the sill and holds the coupler in an operative position. A block or adapter 38, Figs. 2, 6, which is open along a central vertical longitudinal plane is loosely pivoted to angle on the hook by a pin 39, and channel shaped caps 43, 44 are bolted to the sides of the adapter to provide guides for shanks 31, 32 integral with the coupler head and for the thrust blocks 51, 52, the shanks and blocks having flanged ends 71, 64 which cooperate with flanges 57, 55 on the caps to limit outward longitudinal movement of the shanks and blocks with respect to the caps. The channel passages so formed contain springs 75 which force the thrust blocks against the vehicle sill and hold the coupler in a horizontal position. An underbridge or bracket 85 beneath and rigid with the adapter 38, Fig. 4, provides a surface 99 which engages with the undersurface 102 of the sill 8a when the coupler is pivoted down, Figs 3, 7. Corner surfaces 83 engage the front surface of the sill, and a handle 88 pivoted in the underbridge may be swung clockwise to move an arm 93 to the dotted position shown in Fig. 3 where it prevents anti-clockwise movement being given to the pivoted down coupler. To prevent unwanted movement of the thrust blocks 51, 52 in the coupler down position, the toes 111 on latches 105 pivoted at 106, Fig. 6 may be engaged in slots 109 in the bases of the caps 43, 44 so that the thrust elements are locked in position. In an embodiment where the automatic coupling is to be permanently operative and therefore non-pivotal, Figs. 8 and 9 (not shown), the latches 105 and openings 109 are omitted and the abutting surfaces of the thrust blocks extend vertically downwards a farther distance to prevent tilting. The hook need not be exposed for coupling and the lever 93 and the underbridge arrangement are also omitted. In this embodiment the springs 75 provide buffing resistance.

Abstract: 553,056. Chlorination of titanium -bearing materials. CLEVELAND, F. J. (Pittsburgh Plate Glass Co.). March 7, 1941, No. 3143. Drawings to Specification. [Class 1 (iii)] Titanium-bearing materials containing 15 per cent. and upwards of titanium and generally from 10 to 50 per cent. iron, including ilmenite, titano-magnetite or titanium-bearing residues such as titanium oxide, such materials not containing carbonaceous matter such as coke, charcoal or peat or other non-gaseous reducing agents other than such as may be employed as a binder, are chlorinated by a process in which, after initiation of the chlorination, the material and chlorine are introduced into the reaction zone with a gaseous reducing agent provided from an external source at such a rate that the heat evolved maintains a temperature above 600‹ C. in at least a portion of the reaction zone, without introducing from an external source either an oxygen-containing gas or a non-gaseous reducing agent other than such as may be employed as a binder. Carbon monoxide, phosgene, hydrogen, sulphur chloride, carbon tetrachloride and sulphur vapour are mentioned as gaseous reducing agents. Varying the amount of reducing agent renders it possible to produce a titanium residue containing only a minor quantity of iron, or to form and volatilize iron and titanium chlorides in substantial amount and equimolecular proportions of chlorine and gaseous reducing agent may be used. To remove iron without removing titanium a slight excess of reducing agent over that necessary to reduce the iron present to the metallic state is used. To chlorinate both iron and titanium the quantity of reducing agent may be increased up to the quantity theoretically necessary to reduce both to the metallic state. The furnace may be of firebrick and may be preheated by burning coke, and the reaction may be started by burning coke in air or oxygen. Binding agents mentioned are molasses, tar, stillresidue from distillation of oils, asphalt, bitumen, sodium silicate and hydrated titanium oxide. Specification 535,179 is referred to.

Title: Improvements in and relating to electric control systems for the transmission of electric energy to a load circuit through capacitance storage apparatus
IPC: B23K11/26
Filed: 1942-03-17
Abstract: 556,118. Control systems for resistance welding; automatic control systems for condenser charging. BRITISH THOMSON-HOUSTON CO., Ltd. March 17, 1942, No. 3499. Convention date, March 20, 1941. [Class 38 (iv)] Voltage control, thermionic control systems. A condenser 6 is charged to, and maintained at, a definite potential, e.g. 3000 volts, when a main switch 47 is closed and discharged through a transformer 2 supplying a welding or other load circuit when a switch 109 is closed. Closing switch 47 energizes the filaments and space discharge devices from circuit 49 after a time relay 55 energizes relay 44, to remove a short circuit on condenser 6, and relay 51, to commence the charging of the condenser. A discharge device 9 in the charging circuit has a grid 12 which is subject to a fixed positive voltage determined by a glow discharge tube 18, which voltage is progressively annulled by the negative voltage of a potentiometer contact 38 as the condenser charge builds up; any subsequent fall in condenser voltage is prevented by the reestablishment of charging impulses resulting from the fall in potential of contact 38. When the switch 109 is closed to make a weld a relay 79 removes a short circuit on a peaking transformer 86 which overcomes the negative grid bias of a condenser 71 and ignites a discharge device 63 to cause immersion ignition valve 59 to fire and discharge the condenser and a relay 34 applies negative potential to grid 12 to prevent the condenser being charged ; the transformer 86 is fed through a static phase shifting circuit 78. A discharge device 98 is connected through the immersed igniter of valve 94 across the transformer 2 and poled to ignite when the transformer polarity reverses. at which time the grid 99 of the device, which is normally biased to cut off is rendered positive by connection through contacts 108 to the anode of the device 98. The valve 94 is thereby ignited and current through valve 59 commutated to prevent reversal of condenser potential. Contact 108 is closed by relay 106 on operation of switch 109 and opened again after time slightly more than that taken by the condenser to discharge. The valve 94 would therefore extinguish itself towards the end of the collapse of transformer flux but positive cut-off may be obtained to shorten the welding time and avoid sparking at the welding electrodes by connecting a transformer 104 in series whereby A.C. impulses are superposed on the current curve ; saturation of this transformer by the D.C. is prevented by its design. Means for adjusting the phase of the voltage from transformer 104 is provided.
