Title: Welding machine for seam flanges of metallic sheets
IPC: B23K11/31
Filed: 1964-01-29
Abstract: 1,048,942. Welding by pressure. ROSTFRIA TAK A.B. Jan. 29, 1964 [Dec. 10, 1963], No. 3793/64. Heading B3R. A machine 5, Fig. 5, for welding together upright seam flanges 3, 4 of metallic sheets 1, 2, comprises roller electrodes 7, 8 to engage the flanges 3, 4, one on each side thereof and secured on shafts 44, Fig. 7, transversely movable toward and away from each other under the action of a clamping device which yieldingly tends to move the electrodes 7, 8 toward each other, the shafts 44 being driven by a motor 20, Fig. 1, so that the machine 5, upon rotation of the shafts 44 and electrods 7, 8, is advanced along the flanges 3, 4 to join them to form a weld 6 by electric resistance welding. The machine 5 moves on runners or rails 26, Fig. 1, and motor current and welding current, respectively, are fed to terminals 12, 14. The electrodes 7, 8, Figs. 6 and 7, are secured to flanges 42 on the shafts 44 each mounted in a bearing case 46 mounted on a shaft 48 extending through a sleeve-like projection 50 on a plate 36, Fig. 1, carrying the welding head 24. The electrodes 7, 8 can thus be swung about the shafts 48 and are urged towards each other by the clamping device comprising a spring-loaded rod 52, Fig. 6, extending between hook-like projections 54, 56 on the cases 46 by electrically insulating pivots 58, 60, the rod 52 being longitudinally displaceable in the pivots 58, 60. A tensioning device 62 connected to one end of the rod 52 abuts against the pivot 60 and holds spring plates 64 mounted on the other end of the rod 52 against the pivot 58. The device 62 comprises a cam 66 abutting a spacer 74 and rotatable about a bolt 68 by moving a handle 70 upwardly so that the electrodes 7, 8 may be moved apart to enable the machine 5 to be placed with the electrodes 7, 8 positioned one on each side of the flanges 3, 4. The rod 52 comprises two telescopic parts to enable the pressure exerted by the device 62 to be adjusted. The shafts 44 are driven from the motor 20 by gears 90, 92, 94, 96 from the output shaft 88 of a gear-box 22. To prevent overheating of the electrodes 7, 8 cooling fluid is supplied to a duct 57 in each shaft 44 through radial holes 53, 55 in grooves 43, 47, packing rings 51 being provided in grooves 41, 45, 49. In a modification, Fig. 11, for welding seams along non-planar surfaces, the machine is guided manually and the electrodes 7, 8 are arranged with their shafts parallel to the output shaft 112 of the motor 20. The base-plate of the machine carries only the welding head 24, the motor 20 and a gear-box 110, a transformer and conductors (not shown) for the welding current being separately disposed. The tensioning device 62 of the clamping device for the electrodes 7, 8 may be omitted.

In apparatus for feeding bottles A to a washing machine C, the bottles are discharged by a conveyer B into unidirectional rotating inverting mechanism B<SP>1</SP> from which they are delivered through a fixed shoot B<SP>3</SP> and a pivoted shoot D to baskets c of the machine. The mechanism B<SP>1</SP> is a star-wheel preferably formed with three lobes b, each of which has a radial portion bl to support a bottle. The outer end of each part bl is formed as a rib b<SP>2</SP> which tilts each bottle in the direction of travel. Stationary guide plates B<SP>2</SP> on each side of the bottle retain it in position during inversion. The shoot D is carried by an arm d pivoted to the axis of the washing machine. This shoot moves with the machine after receiving a bottle until the latter is housed in a basket. When this occurs the shoot returns to receive the next bottle from the shoot B<SP>3</SP>. In a modification, the guide at each side of the shoot is replaced by a fixed guide B 4 , Fig. 5, and a guide B 5  which is pivoted at B 6 . The position of the guide B 5  is varied by a cam B 7  in order that the ribs b<SP>2</SP> may project different distances into it and so vary the effective widths of the parts b<SP>1</SP> to accommodate bottles of various diameters.

Road-traffic signals on vehicles.-In manoeuvre apparatus for use on motor vehicles, the emergency or stop signal is not operated unless with one brake on the other brake is also applied. The emergency signal may be an electric lamp having in its circuit two switches connected in series, one switch being connected to the foot brake and the other to the hand brake. In a modification using a single switch, a movable contact bar 6 supported by a spring 7 is connected by springs 12, 13 respectively to the operating members of the foot and hand brakes. If the foot brake is operated the bar 6 is tilted until it meets the edge a of a slot 10, and on operation of the hand brake the member 13 pulls the bar 6 into contact with a terminal 9, thus completing the circuit of the emergency lamp 14. In vehicles fitted with direction indicators, the indicator lamps may be in circuit with the contact members 5, 6 so that the indicator circuit is broken simultaneously with the lighting of the lamp 14. A modification is described wherein the bar 6 is mounted on two springs and co-operates with two terminals. A separate switch may be fitted so as to use the lamp 14 as a parking light.

Filed: 1925-02-25
Abstract: 237,553. Atwater Kent Manufacturing Co., (Assignees of Silva, A. de V.). July 26,1924, [Convention date]. Thermionic amplifiers. - The inherent retroaction of a themionic valve amplifier is reduced by inserting an impedance in the connection between a tuned circuit and one of the electrodes. The Figure shows resistances R in the connections to the grids g of valves V, V1, V2; these resistances have a resistance of the order of 600 ohms which is sufficiently small to maintain the decrement of the tuned circuit low. The value of the impedance R is dependent on the amplification factor, plate impedance, grid-to-plate capacity of the valve and a constant depending on the number of valves employed in cascade. The coupling transforms T, T1, T2, have their secondaries tuned by condensers C, C1, C2 and are so arranged that the ratio of inductance to capacity is large. The coupling co-efficient is of the order of 30 per cent between the primary and secondary winding of the transformers. Reference has been directed by the Comptroller to Specification 149,199.
