Abstract: 308,355. Bridger, T. E. March 22, 1928, [Convention date]. Coating; coating non-metallic surfaces with metals. - In a process for spraying metal, especially on to metallic and non-metallic surfaces, the metal to be sprayed is revolved at high speed and is placed under a high electric potential, an intermittent make-and-break contact with the metal being provided so that the metal is fused or broken down and carried into the arc produced from whence it is expelled in fine metallic spray which is deposited on the surface to be coated. Two wheels 1, 2 which revolve at a very high speed are provided with removable peripheral rings 1A, 2A one composed of the metal to be sprayed and the other of a metal of high fusing point. The wheels are mounted on the cranked ends 3, 4 of spindles 5, 6 which are driven from a flexible shaft 7 by pinion 8 mounted on a sleeve 9 on the spindle 5 and engaging a pinion 7A on the said shaft, the upper end of the sleeve 9 being provided with a friction wheel 10 which engages and drives a friction wheel 11 mounted on a sleeve 12 on the spindle 6. The apparatus is contained in a closed casing 15 provided with a mouthpiece 15A. The current is led to the wheels 1, 2 through the spindles 5, 6, non-rotatable discs 18 being secured to the upper ends of the cranked portions 3, 4 of the spindles and provided with depending portions 18A with which contact wire brushes 19 secured to and rotating with the parts 3, 4. To adjust the positions of the rings 1A, 2A so that they are always in contact, levers 20, secured on the lower ends of the spindles 5, 6, are connected by links 21, Fig. 4, to a bridge 22 mounted on guide rods 23 secured to the handle 17 and provided with a trigger device 22A. To prevent oxidation of the sprayed particles, hydrogen or other non-oxidizing gas may be introduced into the casing 15. In a modification, the discs 1, 2 are mounted directly on the spindles 5, 6 and contact not with each other but with a conductor roller or wheel. In a further modification, Fig. 7, the disc 1 is mounted on a spindle 3B and is driven by a belt and the disc 2 on a spindle 4B formed on or secured to the outer end of an arm 32, the other end of which is slidably mounted on pins 33 secured to, but insulated from, the frame. A spring 35 presses against the arm 32 to keep the disc 2 in contact with the disc 1 and a link 36 connected to the arm 32 is also connected by a pivoted lever 37 to a much stronger spring 38 which tends to keep the discs 1 and 2 apart. The action of the spring 38 is however overcome by an insulated cord 39 connected at 37A to the lever 37 and at its other end to a foot pedal. The disc 2 may be replaced by a brush or wipe contact mounted on the arm 32. The discs 1, 2 may be provided with detachable covers and baffles 45 may be mounted so that the primary spray of metal is directed into the secondary spray as shown.

Abstract: 688,801. Launching rockets from aircraft. ROBERT, R. A. April 18, 1951 [April 20, 1950], No. 9018/51. Class 9(ii) Apparatus is provided for launching rockets from aircraft in which the rockets are fed progressively downwards to the firing position, each rocket being fired electrically when current pickup members carried by the next following rocket cooperate with conductors which are shortcircuited until the lowermost rocket is in the firing position. Rocket bombs 201<SP>1</SP>, 201<SP>2</SP>, 201<SP>3</SP>, arranged horizontally in a vertical bank are constrained at the rear end by guide members 202, 203, the lower ends of which are flush with the magazine outlet. As shown in the Figure, the rocket 201<SP>1</SP> has moved into the firing position. The guides 202, 203 comprise upright members 206, 207 coated on the facing surfaces with conductive plates 208, 209. The plates are maintained at the same potential by electrical connections throughout their lengths. Below the plates 208, 209 are conductive strips 210, 211 connected to opposite poles of a source of potential and secured on insulating strips 212, 213. A cap member 215 is secured by resilient fingers 216, 217, 218 to the rear 214 of each rocket. In each cap is an electric plug socket 219 with contacts 220, 221 receiving a plug 222 and connected by a lead and a friction finger 223 with the plate 208 or strip 210 and similarly with the plate 209 or strip 211. The leads from the plug 222 extend thorugh a cable 225 into the next rocket below and are connected to a firing device for that rocket. The cap member 215 carries two diametrically opposed stops 230 which maintain the tail fins in a folded position until the rocket has been fired. The movable part 231, 236 of each fin is urged to the extended position by springs 233, 237 surrounding the pivot pins, 234. As the rockets are fed to the magazine outlet the friction fingers 223, 224 are in engagement with the plates 208, 209 so that no current can flow through the cables of the cap members. These friction fingers escape from the plates into contact with the strips 210, 211, as the rockets move into the pre-firing position, while in the firing position the fingers are free from the strips 210, 211. Thus no current can pass through the firing device of each rocket until the rocket is in the launching position. With the rocket 201<SP>2</SP> in the pre-firing position, its fingers 223<SP>2</SP>, 224<SP>2</SP> being in contact with the strips 210, 211, the cable 225<SP>2-1</SP> is traversed by a current and the firing device for the rocket 201<SP>1</SP> is energized and the rocket propelled forwardly. The propulsion gases force the cap member 215<SP>1</SP> rearwardly away from the rocket and the rocket 201<SP>2</SP> moves into the firing position.
