Filed: 1973-10-29
Abstract: 1440836 Sink-float separation PROCESS EVALUATION & DEVELOPMENT CORP 29 Oct 1973 [27 April 1973] 50197/73 Heading B2H [Also in Division Dl] In a method of removing foreign matter such as stones, gravel and coarse sand from fibrous material the material is repeatedly immersed and refloated in a liquid flotation medium, e.g. water, in a U-shaped tank. The foreign matter being loosened and removed in the loop of the V, the fibrous material being transported from the loop and removed from the liquid. An apparatus for performing this method comprises an elongate open V-shaped tank 11 with means, e.g. chute 15, to introduce dirty fibrous material, means to repeatedly dunk the fibrous material, e.g. rollers 21 to 28 with fingers 19, and a sloping foreign matter collecting zone 17 in the loop of the V. A discharge device 18 is located at the bottom of zone 17. The liquid medium is drained from the fibrous material at the outlet end of the tank, if necessary with the assistance of pressure rollers and the water is recirculated. Separation of the foreign matter can be assisted by the introduction of air through a sponger 51. In the outlet leg of the tank the roller centres are arranged progressively higher and follow a sloping tank bottom 35. A trap door 35g can be operated if it is necessary to recycle the fibrous material through the tank. The final rollers 26, 27, 28 have smooth metal end plates 19a on the fingers 19 and the roller 28 additionally has rubber flaps 19b to give a squeegee-like action on the perforate tank bottom 35a. The foreign matter discharge device 18 is a tubular section with gate valves 31, 32 allowing periodic removal of foreign matter while the apparatus continues to operate.

Title: Improvements in or relating to apparatus for applying ribbon-shaped ties to articles
IPC: B65B51/08
Filed: 1964-12-14
Abstract: 1,087,200. Twisting wires together. ROYAL INDUSTRIES Inc. Dec. 14, 1964 [Feb. 3, 1964], No. 50846/64. Heading B3E. [Also in Division B8] A device for passing a flat strip of binding material, such as wire-reinforced paper, part way round an article, e.g. a gathered bag neck, and securing the ends by twisting, comprises means to feed the strip through a severing head to a folder which bends it to U form about the article and places its end in the path of a rotary twisting head, the fed length passing adjacent the head on its way to the folder, the head then rotating with substantially simultaneous severing and twisting of the strip length. Strip 16 is fed from a reel (not shown) by a friction sector 40a on a disc 40 through a fixed member 59 with a cutter face 64 to lie adjacent a flat 81, Fig. 5, of the twister 54. The device is driven by a continuously rotating motor through a one-revolution clutch which is connected to a shaft 50 carrying the disc 40, a sector gear 36 and a plain disc sector 38. During twisting the gear engages a pinion 74 on the twister shaft 60 which also carries a cutter disc 56. In operation, a bag neck 8 thrust into a throat 13 rotates a trigger 84 clockwise to pull to the right and then release an arm 90. The arm causes pivoting of a stop member 32 about a pin 97 to disengage a step 28 on the clutch 26 so that the shaft 50 rotates. Strip is fed to the position of Fig. 1 while rotation of the twister shaft 60 is prevented by the plain sector 38 engaging a flat on an extension 76 of the shaft. A cam 52, also on the shaft 50 then permits a lever 104 to rotate anti-clockwise about a pivot 106 so that a folder arm 98 moves from the position of Fig. 1 to that of Fig. 2 to bend the strip about the neck 8 and place its end adjacent the twister flat 80. The gear sector 36 now engages the pinion so that the twister 54 and cutter 56 rotate with consequent severing and twisting to form the finished closure. A guide 181 forces the tie against the back portion of the twister head to cause tight twisting.

Filed: 1971-11-18
Abstract: 1356799 Carburetter throttle valves FORD MOTOR CO Ltd 18 Nov 1971 [4 March 1971] 53536/71 Heading F1B A carburetter throttle valve 22 can be positioned in either a fully closed or idle position 34, 36 respectively, the fully closed position arising on shutdown of the engine and during deceleration. Throttle valve 22 is allowed to close only as far as the idle position 36 by actuator 52 of vacuum servo 42 unless a valve 68 is opened by a spring 71 to connect the vacuum servo to a vacuum reservoir 66 which is charged via a restrictor 64. Valve 68 is held closed by a solenoid whose coil 76 is in series with a manifold vacuum controlled switch 80 and ignition switch 72 when these are both closed as in normal running. On deceleration, the vacuum applied to switch 80 via line 92 is enough to open contacts 84 so allowing valve 68 to open to apply vacuum to servo 42 so that the throttle valve can fully close. When ignition switch 72 is turned off, the throttle valve is similarly allowed to close fully by the action of servo 42, but because the vacuum in reservoir 66 decays over a few seconds, the throttle valve resumes the idle position 36 for restarting the engine.
