Abstract: 216,668. Smith, J., and Thompson, F. May 7,1923. Coin action, with h delivery proportionate to value of coin; diverting i m p r o p e r coins. - In a coinfreed vending machine having diverting means to cause coins to move along a desired path, and of the kind in which a pivoted cam lever or plate is connected to a diverting lever which is thrown across the path of the coin when this operates the cam lever, the cam and coin diverting levers are mounted so that they move in the same plane or in parallel planes. In apparatus for selling- sixpenny, penny, and halfpenny articles, thecoins being inserted in a single slot communicating with a vertical shoot 48, Fig. 1, the sixpence drops down the shoot to release mechanism 156 while the penny and halfpenny are diverted into side shoots 49, 50 respectively, and a farthing into a return shoot 57. The diverting means comprises a cam lever 51 pivoted at 53 and connected by an encircling pin 55 to a diverting lever 52 below the parallel pivot 54 of the latter. The cam lever normally reduces the width of the shoot 48 and the rim of the coin moves it into a recess 56 thereby setting the lever 52 across the shoot 48 to direct the coin into the proper shoot. Means for preventing the operation of the vending machine by coins &c. which are too thin comprise a pivoted member 58, Fig. 2, forming one wall of the coin aperture and having hooks 61 engaging a diverting lever 60 below its pivot 62. A proper coin is directed into the proper channel while a thin coin passes straight through to be returned or to fall into the coin drawer. The member 58 is provided with an adjustable plate 63 secured by an adjusting screw 64 to adjust the coin aperture for thickness of coins.

Abstract: 129,830. Roberts, G. H., and Booth, W. N. Jan. 27, 1919. Muffle furnaces; crucible furnaces; metal-heating furnaces.-In a furnace of the type in which the outer walls are separated from the walls of the heating-chamber by a space through which the waste gases circulate before passing to recuperators, the recuperators are situated in a flue below the furnace and surrounded by the outer walls. The waste gases flow in the opposite direction to that of the air or gas, or both, being heated. In the gas-heated muffle furnace shown ia Fig. 5, combustion gases pass around a chamber A, and the waste gases pass by openings a to the space b and thence to a flue below the furnace, where they heat the air for combustion in pipes G, G<1> provided with radiating-gills, and the gas in a pipe N with branches leading to two burner nozzles. A layer of heat-insulating material E may be disposed within an outer casing F. In a modification provided with a single burner, the fuel gas and air are preheated together in a single gilled pipe. Fig. 9 shows a crucible tilting furnace wherein combustion gases from burners M ascend around a crucible A, pass through holes a, and descend a jacket flue b<1>, heating the gas in an annular tube 0, and the air in a pipe G branched in the flue D to give greater heating-surface. Fig. 11 shows a billet-heating oven furnace supplied with hot gas from producers through an intake Q, the waste gases, aftet passing through the jacket b, heating air in pipes G<2> within a flue having an outlet R.

Abstract: 824,996. Colour television. ADMIRAL CORPORATION. April 16, 1957 [June 1, 1956], No. 12386/57. Class 40 (3). [Also in Group XL (c)] Apparatus for producing a continuous wave signal from television colour signal bursts comprises a circuit which is caused by the bursts continuously to ring and which provides an output which is applied to an oscillator to cause it to produce a signal of known frequency and phase relation to the output of the ringing circuit. The Figure shows part of a colour television receiver comprising an input capacitor 39 to which the colour video signal is applied. The valve 35 is self-biased by the voltage across the capacitor and is gated by a pulse applied to cathode winding 45 from the line output transformer, the pulse being shaped and delayed by a circuit 41, 42 and being timed such that only the colour synchronizing signal bursts pass through the valve. These bursts cause a circuit comprising a crystal 53 and a balancing capacitor 51 to ring continuously. The ringing voltage is applied to an electron coupled Colpitts oscillator 65, to synchronize its operation. The resulting output signal is obtained from a transformer 82 and applied to the demodulator of the receiver and a voltage for operating a " colour killer " circuit is derived from the grid of the oscillator.

Abstract: 1,056,143. Circuit assemblies. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. March 18, 1965 [March 24, 1964], No. 12396/64. Heading H1R. In an electrical circuit module in which terminal members from the components in the module extend through an end face of the module, the said end face is formed with a plurality of transverse slots which accommodate conductive members extending from positions of connection with said terminal members to positions adjacent opposite edges of said end face, at which latter positions at least some of the conductive members are formed with tag portions extending away from the end face. As shown, Fig. 1, a module comprises a bobbin 1 carrying a coil 2 and four sealed reed contact units 5. Terminal members 9, 9<SP>1</SP> from units 5 and coil 2 respectively, pass through an end check 4 and an end plate 7 which is placed against end check 4, quadrantal corner projections 11 on the latter mating with corner cut-outs on the end plate. Conductive members 16, located in parallel slots in the end plate 7, have connecting portions 21 to which terminal members 9, 9<SP>1</SP> are soldered, and tag end portions 17 which over-hang the limits of the module so that adjacent modules may be interconnected by the soldering together of overlapping tags. Other conductors may have only one tag 17 (e.g. conductor 18) or no tag (e.g. conductor 19). Alternatively, the tag portions may be turned through 90 degrees (Fig. 5, not shown), in which case abutting tags of adjacent modules are soldered together. Similar conductors are located in slots in end check 3, such conductors extending normal to conductors 16, as shown, or alternatively lying parallel thereto. Terminals from the units 5 passing through end check 3 are soldered to connecting portions on the appropriate conductors, while a second terminal from the coil 2 is brought out through a slot in end check 3 and soldered to a flat bollard on a conductor. Alternatively, a second end plate similar to 7 carrying the conductors may be employed in conjunction with end check 3. A diode 26 may be accommodated within the module, terminals 27, 28 therefrom being brought out through end check 4 and end plate 7 and sol dered to connecting portions 21 of conductors 18, 19, as shown. A screening member (not shown) embraces the coil on three sides. A plurality of adjacent modules are held together by spring clips around corner projections 10, 11 as described and claimed in Specification 1,054,772. In a modification, Figs. 4, 4a, 4b (not shown), conductors 16 are retained in slots 46 by transverse strips 48, and quadrantal projections 10, 11 are notched to facilitate the use of a tool for applying and removing retaining clips.
