Title: Improvements in apparatus for the supply of electric current to travelling cranes
Inventor: LEE SAMUEL
IPC: B66C13/12
Filed: 1962-12-01
Abstract: 979,862. Power supply for overhead travelling cranes. S. H. HEYWOOD & CO. Ltd. Nov. 22, 1963 [Dec. 1, 1962], No. 45565/62. Heading B8B. Electric current passes from a junction-box C, Fig. 1, to a box A<SP>2</SP> on the crab A<SP>1</SP> of an overhead travelling crane through a cable B which passes round a drum D on a carriage A supporting the crab. The carriage A is traversed across a bridge C<SP>1</SP> on wheels c, Fig. 5, by a rope b the ends of which are secured adjacent the two junction-boxes. This rope also moves the crab on the carriage and as these movements take place the cable B is picked up from the bridge C<SP>1</SP>. The upper run of the cable is supported by brackets a, Fig. 3, on the carriage. A second cable or cables may pass round a drum D<SP>1</SP>. To reduce the length of the bridge over which the carriage travels a second carriage may be mounted over, under or side by side with the first carriage. One cable links the two carriages and a further cable links the crab thereto. If necessary a third carriage may be provided.

Title: Improved reinforcing elements for ferroconcrete constructions
IPC: E04C5/04
Filed: 1962-12-03
Abstract: A grid-like reinforcing element comprises a plurality of steel bars connected to one another at the points of interaction by means of a synthetic plastics material glue.  The steel bars pass longitudinally under a pressing tool where their points of intersection with transverse terms are flattened and a measured amount of glue is added.  They are then moved forward in a step movement to a press beam under which the transverse bar are passed and adhered to them, heating elements being provided to prepare the glue.  The transverse bars may be passed between squeezing rolls to flatten points of intersection with the longitudinal bars or alternatively neither set of bars need be flattened.

Abstract: 1,080,269. Gas-blast circuit-breakers. WESTINGHOUSE ELECTRIC CORPORATION. Nov. 4, 1965 [Nov. 19, 1964], No. 46748/65. Heading H2B. When a dual-pressure gas-blast circuit-breaker is opened, gas from a high pressure reservoir is applied to a piston 29 causing it to open a blast valve 27 and to move one contact 51 away from a co-operating contact 66 to interrupt the current through the circuit-breaker. Then the venting of high pressure gas from a cylinder 57 to the left of a piston 59 permits high pressure gas acting on the right of the piston 59 to cause this piston to move the contact 66 to provide an isolating break. Subsequently gas passing through a bleed hole 46 in the piston 29 equalizes the pressure on both sides of the piston so enabling a spring 28 to move the piston 29 and contact 51 back to the initial position and to close the blast valve 27. To reclose the circuit-breaker, high pressure gas is admitted to the right of the piston 59 to move the piston and contact 66 to the closed position shown. A resistor, Fig. 3 (not shown) may be connected between the contact 51 and a spring-biased fixed auxiliary contact which co-operates with the contact 66. Fig. 1 (not shown) illustrates the valves and control circuits for the circuit-breaker, certain of the valves being common to all the poles of a multi-pole arrangement.
