The crank-shaft 16 shown is turned by a gear-wheel 18 driven through a flexible drive shaft by an external I.C. engine or electric motor. A chisel 31 may be resiliently mounted and struck by the hammer piston; alternatively, the impact tool may be a ramming stamp which is attached to the hammer piston. The cylinder 21 can communicate with atmosphere via ports 25, 26 when opened by the passage of the piston. During an upstroke of the cylinder 21 with the lower ports 26 closed, the air is compressed in the lower chamber until the cushion of air is such as to move the piston on its upstroke to close the upper ports 25 and compress the air trapped in the upper chamber. During the downstroke of the cylinder 21, compression of the air above the piston is completed before the piston is compelled to move downwardly on its working stroke by the compressed cushion of air. As soon as the lower ports 26 are closed, the air trapped in the lower chamber begins to be compressed. The ports may be replaced by a single large port or a slot. Handles 37 are resiliently-mounted on buffer springs 35. The rotary mechanism on the tool may be a cam or eccentric instead of the crank shown.

Title: Improvements in or relating to thermostatic control devices for gas ovens
IPC: G05D23/02
Filed: 1945-01-08
Abstract: 587,709. Temperature-responsive actuating- elements. BRITISH THERMOSTAT CO., Ltd., and SHERLOCK, J. E. Jan. 8, 1945, No. 647. [Class 64 (ii)] [Also in Groups XIV and XXIX] A temperature control device for a gas oven comprises a gas cock 3 and a thermostatic valve 7 which is operated by the differential expansion of a brass tube 15 surrounding a rod 14 of non- expansible metal disposed in an oven the operating temperature being determined by a rotatable knob 2 which adjusts the position of the brass tube 15, and is situated at a point remote from the cock and valve. Rotation of the knob 2 transmits axial motion to the tube 15 which carries gears 19 meshing with the gears 20 to open the gas cock 3, and allow gas to flow from the inlet 5, via the valve 7, which is normally held off its seat 8 by the rod 14 against the action of a spring 9, to the outlet 10. Passages 12 and 13 provide a bye-pass. When the gas cock is open, further rotation of the knob 2 merely adjusts the position of the tube 15, and hence the rod 14 to which it is attached at its end near the knob, .since the gears 19 and 20 no longer engage. The tube 15 is in screw-threaded engagement with the housing 11 at 17 to enable its position to be adjusted. A spring-loaded button 21 radially disposed in the knob 2 co-operates with a fixed viser 22 to prevent accidental turning on of the gas. In a modification, Fig. 3, the knob 2 is connected to the brass tube 15 by a flexible transmission device, e.g., a Bowden cable 24, to a pulley wheel 25, which has a slot or recess 26 in permanent engagement with an arm 27 fixed to one end of the brass tube 15.

Abstract: 977,731. Welding by pressure. AMALGAMATED DENTAL CO. Ltd. Jan. 3, 1961 [Jan. 7, 1960], No. 674/60. Heading B3R. In welding hardenable stainless steel to cemented tungsten carbide or to austenitic stainless steel, a third metal, capable of wetting the hardenable stainless steel, is inserted between the components to be welded. The components are welded directly together without being bridged by a third metal as in brazing. A stem 3 of hardenable stainless steel (12-18% Cr, 0.1-0.8% C) is carried in a water-cooled copper electrode 1 and a sintered tungsten carbide cylinder (not shown), with 6-15% cobalt, of the same diameter is located in a nickel-chromium alloy collet 6 on a disc of platinum on a copper electrode 7. The upper electrode loaded by a weight 8 is lowered and a shim of 33% Cu-67% Ni alloy, larger in diameter than the stem, is placed between the stem and cylinder and a flux, e.g. a fluoride based flux incorporating nickel powder, is placed between the shim and the cylinder. A control apparatus causes preheating oxyacetylene flames to be applied to the work to preheat to 600‹ C and then the application of current to the electrodes to effect a resistance weld. The parts are then allowed to cool in the reducing flames. The tungsten carbide may be a dental bur tip welded to a stainless steel shank and tips may be welded simultaneously to both ends of a shank. Other metals for insertion between the parts are copper 50-80% nickel alloys; platinum; platinumrhodium alloy; pure iron; high speed steel; cobalt-tungsten-iron alloys; nickel; cobalt; copper; nickel-iron alloys and nickel-chromium alloys, some being in foil or powder form. The hardenable stainless steel may comprise 10-18% Cr and less than 1% Ni.

Abstract: 875,718. R.F. couplings. MARCONI'S WIRELESS TELEGRAPH CO. Ltd. Sept. 8, 1959 [Jan. 7, 1959], No. 693/59. Class 40(7) To prevent difficulties arising due to mis-match between a driving source and a power amplifier the amplifier is divided into two similar units fed from the source by means of a hybrid network. The network is arranged so that the outputs to the amplifiers are in phase quadrature and the hybrid is provided with an absorber load arm to absorb substantially the whole of any energy reflected back from the amplifiers. The amplifiers feed a common output channel. In one embodiment an H line hybrid is used comprising four #/4 lines in ring formation with one of the two lines connected at each of the four junctions having a characteristic impedance of Z0 and the other an impedance of Z0/#2. With the driving source connected to point 1 of such a hybrid phase quadrature outputs are obtained from points 5 and 6 for application over equal length lines to amplifiers Al and A2. Signals reflected from the amplifier inputs are in antiphase at point 1 and in phase at point 4. They will thus not affect the driving source but be absorbed by load R1. The outputs of the two amplifiers may be combined in phase by a further hybrid H3. Specification 723,151 is referred to.
