Title: Improvements relating to the welding of fins to tubes
Inventor: HALL ARTHUR SAMUEL
IPC: B21C37/22
Filed: 1964-03-20
Abstract: 1,092,633. Welding by pressure; making finned tubes. TUBE PRODUCTS Ltd. Jan. 7, 1965 [March 20, 1964; Sept. 8, 1964], Nos. 11803/64 and 36683/64. Headings B3A and B3R. In continuously welding a straight longitudinal or helical fin to the surface of a tube by electric resistance welding, the edge of the fin which is applied to the surface is shaped to provide one or more sharp or narrow ribs or crests which are continuous and engage the surface of the tube initially so that the heating effect of the current is initially concentrated in the ribs or crests. The fin may have a chamfered end to provide a single welding edge and two such fins 15, 16, Fig. 3, may be welded to a tube 17 by a pair of grooved roller electrodes 18, 19. The current flow is from one electrode through the tube to the other electrode. The fin may be of greater radial length with a blunt edge remote from the edge to be welded. The inner edge of the fin 29, Fig. 7, may have two parallel crests, separated by a groove and the crests may be knife edged, may have narrow lands or may be radiused. More than two crests may be provided and they may lie on a curve or in a flat plane. Instead of supplying current through the grooved rollers the current may be supplied to the sides of the fin through separate roller electrodes 32 or sliding contacts. Opposed fins may be wound helically on a tube and welded by grooved roller electrode inclined to the tube axis and the rollers may be idle or driven. Opposed straight longitudinal fins may be welded to a tube by grooved driven roller electrodes. In making a tube plate opposed fins are welded to tubes and the outer edges of the fins are welded together. Alternatively a number of tubes each having one fin welded by the described method are formed and the free edge of each fin is welded to the unfinned side of the adjacent tube.

Title: Improvements in electric switches
IPC: H02B1/28
Filed: 1925-05-14
Abstract: 254,845. Sykes & Dyson, Ltd., and Sykes, P. May 14, 1925. Switches, quick-action of the dead-centre type, have mounted on a rod carrying the switch blades the boss of a short arm carrying a pin working in a transverse slot in the end of a link pivoted about its lower end, the pin bearing on a collar which confines a spring beneath itself. The casing a is provided with a lid b and carries spring contacts c and fuze bridges. Blades e corresponding numerically to the contacts c are mounted on a rod f journaled at its ends in the casing a, the rod carrying a short arm g through which passes a pin h engaging a slot i<1> in a plunger i. The latter is recessed at i<2> to engage a ball rotatable in a recess a' or may be mounted to rotate about a pin. The pin h bears on a washer k movable loosely on. the plunger and serving to confine a spring l between itself and an enlargement i<3> on the plunger. The dead-centre position is arranged at the point in the movement of the rod f where the contacts are about to engage, so that directly the blades are freed they are accelerated to full open position and in closing they are moved slowly to near the position of first contact and are then accelerated to full contact position. Projections g<1>, g<2> limit the travel by engaging the plunger, and in a multi-contact switch a number of spring devices may be used, for example one at each end of the rod and the other at an intermediate point or points. For interlocking the switch mechanism with the lid b the handle m has a projection m<1> co-operating with a projection b<1> on the lid to prevent opening the latter when the switch is closed and a second projection b<2> on the lid prevents movement of the handle to close the switch while the lid is open.

Title: Improvements in or relating to a system of heating, e.g. a building, by the circulation of hot water
IPC: F24D3/10
Filed: 1957-04-17
Abstract: 826,279. Heating buildings; hot water supply systems. BROSENIUS, K. H. April 17, 1957 [April 18, 1956], No. 12548/57. Classes 64(1) and 64(2) An insulated hot water tank 2, with an expansion tank 24, contains a heat exchanger 20 (in which a domestic water supply is heated) and is connected through a pump 17 to radiators 16a or other heat consumers, the pump being controlled for intermittent operation by a thermostat 18 in one of the rooms heated by the radiators. The bottom of the tank is at substantially the same level as the bottom of the water chamber of he boiler 1 which feeds it. The return conduit 9 from the accumulator tank 2 to the boiler 1, instead of communicating through the tank wall near the bottom as at 9a, does so at the same level as the supply pipe 8 but communicates with the bottom part of the tank only, by way of a conduit 10 which is of large bore and which may be a channel member, Fig. 1a or a sheet metal tube and may be covered with insulation 11 such as cork. This arrangement is said to obviate the return of hot water to the boiler when the firing of the latter ceases. In one embodiment, Fig. 2 (not shown), the pipes 8, 9 pass through the wall of the accumulator tank 2 near its top and in this embodiment, sheet metal flues of the boiler may have a surrounding water jacket communicating with the tank 2. An expansion tank may fit loosely in the top of the tank 2 as a cover, Fig. 3 (not shown).
