Title: Improvements in or relating to processes for the manufacture of welded rail joints without turning the rails and welded rail joints obtained by these processes
IPC: E01B11/50
Filed: 1946-05-01
Abstract: 635,686. Uniting by fusion. CARPMAEL, M. H. (Soc. Anon. des Ateliers de Secheron). May 1, 1946, No. 13241. [Class 83 (iv)] In making a rail joint by electric arc welding with coated electrodes a gap is left between the rails and supporting members are placed at least opposite the foot and web portions and the gap then filled with weld metal. The rails are separated, preferably by electric arc cutting, by a gap preferably greater than 10 mm, i.e. from 12 to 16 mm., a support plate 4 of copper with a recess 5 to form a bulge reinforcement thickening in the joint is placed under the gap which is filled with weld metal between the feet. The thickenings 9, 10 of weld metal are tooled at 11-14 so that no trace of the edge of the weld is visible. A grooved support of copper, iron, carbon or fireclay is then applied over the gap at the web and weld metal applied so as to project from the gap to form a reinforcement. Two further grooved supports are then placed under the head of the web and weld metal, similarly applied. The gap in the rail head is then filled with weld metal from electrodes of higher carbon content. In a modification the web support and one of the head supports may be replaced by a support 15. The thickening on the under side of the foot may be partly obtained by bending down the rail foot at 16, weld metal then being applied at 19 and 18. Pieces of metal may be applied and covered with weld metal when a large quantity of metal is required. In another form the webs may be slit at 23 prior to bending, which may be effected either hot or cold or bending may be dispensed with. In a further form the end of the feet are upset at 28, 29 prior to applying the weld metal. The copper support plates may be replaced by iron plates which form part of the joint.

Abstract: 1,146,576. Controlled non-linear inductors; transistor oscillator switching circuits. ClTCOMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS. 25 March, 1966 [26 March, 1965], No. 13391/66. Headings H3B and H3T. A non-contact-making relay comprises a saturable core CM having at least one control winding ec, the magnetization of the core by the control winding determining the degree of coupling between two windings eo 1  and eo 2  in the base and collector circuits, respectively, of a transistor oscillator TR, and hence controlling on-off operation of the oscillator. A load R L  is connected between the collector and a source of collector voltage- U (terminals P, Q being linked), and carries a unidirectional output current when the oscillator is functioning. Increase of control current in either sense to a value where the rectangular hysteresis loop core saturates terminates oscillation. When oscillation is commenced by reducing the control current, the oscillatory condition is sustained by a condenser C. The difference between the threshold control currents for operation and release may be minimized by a high resistor (r 2 ) connected between collector and base, Fig. 4 (not shown), and lower value resistors (r 1 ), (r 3 ) in the emitter and base circuits. The core includes a polarization or bias winding ep, and a positive or negative feedback winding er which is connected into circuit by removing the connection PQ and linking terminals P to M and Q to N. Stable operation in response to a single pulse may be obtained by connecting this feedback winding for positive reaction.

Pulses are produced from NAND gates 21, 24 respectively on the insertion of 25 c. and 50 c. coins these pulses being applied via a gating network 13 to appropriate ones of flipflop circuits 32, 49, 57 and 62 (each comprising a pair of cross-coupled NOR gates) depending on the value of the coin and the total value already accumulated in the memory circuit 12 and after a time delay provided by multivibrator 34 the outputs of the set of flip-flops are applied as inputs to corresponding flip-flops 42, 50, 58 and 63 in the memory circuit 12. The outputs of AND gates 64, 69 and 72 and the output 7.6 of flip-flop 63 respectively provide indications of total credit of 25 c., 50 c., 75 c. and $1.00 and are connected via a socket (68) to external selector means to enable selections to be made up to the corresponding value (Figs. 1 and 7, not shown).
