Title: Dual-energy percussive arc welding system
IPC: B23K9/22
Filed: 1966-06-24
Abstract: 1,088,733. Control systems for percussive arc welding apparatus. SIPPICAN CORPORATION. June 24, 1966 [June 30, 1965], No. 28284/66. Heading H2H. Percussive arc welding apparatus comprises two electrodes E1, E2 to be welded together, the electrode E2 being held in a fixed holder H2 and the electrode E1 in a holder H1 movable by a solenoid W, S so as to bring the electrode E1 into impacting contact with the electrode E2 when welding together of the two electrodes is required. Closure of a switch SW1 energizes a transformer T to charge two capacitors C1 C2 over the contacts 1, 2 of a relay RLY, which, when energized, closes the bottom contact of contacts 2 before that of contacts 1. Operation of a push-button PB1 by the welding operator energizes relay RLY to change over the contacts 1, 2. The potential of capacitor C2 is then applied across the electrodes E1, E2 and the potential of capacitor C1 subsequently applied to the winding W of the solenoid. The solenoid thus carries the electrode E1 towards the electrode E2 and when the electrodes are at a predetermined spacing an arc is struck due to the potential thereacross. This causes melting of the ends of the electrodes and the continuing movement of the solenoid brings the electrodes into impacting engagement, whereupon welding together of the two electrodes is achieved. The speed of advance of electrode E1 is controlled by a variable resistor R1 and the potential across the electrodes adjusted by a variable resistor R2.

IPC: D21C5/02
Filed: 1927-10-25
Abstract: 279,516. Grenaudier, L. Oct. 25, 1926, [Convention date]. Pulp, preparation of.-In the recovery of pulp, particularly wood pulp from printed paper, and the removal of ink therefrom, the material in a wet or dry state is reduced to small pieces, then boiled in a solution of soap containing 1 part per 1000 with constant stirring and skimming, the boiling being continued until the scum has become nearly white. The material is then rinsed with ordinary water, pulped in a beater and then boiled in a solution of weak alkali, preferably sodium carbonate containing 1 part per 1000, hot water being added during the boiling to dilute the solution at the end of this boiling operation to 1 part in 1500, with stirring and skimming, the operation being continued until the scum is white. The product is finally rinsed with ordinary water. The heating may be done before the first boiling, and, for the production of pasteboard or coloured paper, the boiling with soap solution may be omitted.

Title: Improvements in pumps
IPC: F04B47/00
Filed: 1921-10-25
Abstract: 191,510. Wilson, E. C. Oct. 25, 1921. Assembling parts.- Relates to deep well pumps in which the working barrel and the footvalve and its casing can 'be removed along with the pump-rod and consists in a construction in which the barrel is forced positively on to its seat and the valve casing is resiliently forced on to its seat. In the construction shown in Fig. 1, the tube 10 forms the delivery pipe and is connected by coupling- collars to extensions 17, 11 the lower of which carries a tapered seating 38 for the foot-valve casing 41 which is tapered to correspond. The part 19 of the outer casing is tapered internally to receive a similarlytapered portion 26 on the barrel 12 which forms a stuffing-box for the plunger 13. When the pump-rod 14 is pulled upwards a flange 49 on the lower end of the plunger engages the tapered part 26 of the barrel 12 and the latter is thus raised with the rod 14. The flange 49 in rising further engages the head 50 of a rod 16 to which the foot-valve casing 41 is secured and the latter is thus raised with the other parts. In lowering the parts into place, the rcd 14 is pushed down until the flange 37 on the plunger comes into contact with the gland 27 of the barrel 12 which can thus be pushed down to force the tapered parts into firm contact. A spring 52 forces the foot-valve casing into its seat. Various modifications are described and shown.

Title: Method and apparatus for facilitating the starting and the landing of aeroplanes
IPC: B60V1/00
Filed: 1922-10-21
Abstract: 187,627. Soc. Anon. des Ateliers d'Aviation L. BrÚguet. Oct. 22, 1921, [Convenation date]. Starting; stopping way; runners and skids.-When taking off from or alighting upon land or water, the air below the wings of an aeroplane is maintained under pressure by a fan or air-compressor driven by either the main motor or by an auxiliary engine. In the application of the invention to a monoplane, front and rear flaps b, e, Fig. 1, are pivoted at the under surface of the wings A, side flaps h, Fig. 2, also being pivoted to the wing tips at points g. All the flaps b, e, h are provided at their lower edges with a strip of leather or indiarubber c, f, q, and the rear flap e is made of a flexible material to conform when closed with the curve of the wing A. In a modification the rear flap is formed by the wing itself, the rear portion of which is hinged and provided with a rubber edge. On landing, as the flying speed diminishes and the air pressure decreases, the flaps b, e, which are connected together for simultaneous movement by rods k, m, l, are opened by a spring R, the movement of the rod m clutching in the fan M. At the same time the pilot lowers the side flaps h by releasing the cables r. The flaps exert a braking action when landing. When taking off air is forced into the receptacle formed by the flaps, the wings and the ground or water, and on a sufficient flying speed being attained, the flaps b, e, are closed by the air pressure, thereby automatically stopping the fan M, and the pilot raises the side flaps h.

A machine for automatically feeding and " running " bolts, set-screws or nuts, comprises three parallel cylinders 1, 2 and 3, Figs. 2 and 6, arranged close together in a triangular cluster mounted in a vertical head 4. The cylinder 1 constitutes a magazine into the forward end 1A of which a vertical guide 5 projects. The components 6 (bolts in the example shown) are fed from the guide 5 one at a time by an escapement device 8 into the part 1A. A push-rod 7 connected by a rod 8 to a pneumatically-operated slide (not shown) pushes the component into a socket 21 carried by a pivotal arm 22, Fig. 3, operated by means carried in the third cylinder 3. The arm is attached to a bush 27 which through a pin 28 and slots in the bush is constrained to rotate during a reciprocating movement of an airoperated piston to which the bush and pin are also connected. The socket 21 and component therein are thus brought into alignment with the axis of the tube 2 which is provided with a spindle 39 and chuck 38 for " running " the component. The spindle is driven by an air motor (not shown) and the chuck 38 may be magnetic.
