The bar 19 is connected to the ends of the levers 27, 29 by ball-and-socket members 55, 57, the ball, e.g. of steel or P.T.F.E. of each member being formed on shafts 49 which are slidably mounted, against the action of springs 53, in the levers. The levers are pivotally mounted on brackets 35 and are each provided with a slot 81 defined by a bar 75 and spaces 77, 79; a crank-pin 71 operates within the slot and is rotated via a gear-box 59. The gear-box is driven by an electric motor 31, which rotates a flywheel 83 coupled to the clutch 33 by a belt 85. The movement of the bar 19 is transmitted to the punches 21 by means of respective abutment pins 137. When certain selected punches are not required, their respective pins are withdrawn thereby allowing. the selected punches slide freely within a retaining member 141 on the bar during a punching stroke; notches 161, Fig. 4, are formed in the punches in order to permit such free sliding movement. The pins are retained in their operative or inoperative positions by means of a rubber block 165 engaging a projection 159 on each pin; the rubber is faced with a skin 167 of, e.g. flexible copper to prevent wear by movement of the projection thereover. The single rubber block may be replaced by separate resilient members, e.g. one for each pin. The clutch 33 and a coacting brake 111 are both electromagnetic which, together with the motor 31 are controlled by an electronic circuit Fig. 7 (not shown). The punching stroke may be initiated by actuation of a foot-operated switch 183 or, automatically by a switch 185 when the material is inserted into the machine.

Title: Recovery of wax from mixtures of wax and feathers
IPC: A22C21/04
Filed: 1954-02-12
Abstract: <PICT:0770293/III/1> Wax, used for dipping poultry to facilitate the removal of the feathers, is recovered from the mixture of wax and feathers by subjecting the mixture within a perforated container to the action of steam and pressure in such manner that the wax is melted and forced out of the container.  In a suitable apparatus, the mixture of wax and feathers 28 is placed in a square container 10 having a base 11 and sides 12, the base and lower portion of the sides being perforated.  The container 10 is mounted on legs 13 and stands in a water-bath 14 above the water level, and the lower perforated part of the container is surrounded by a casing 15 extruding below it and having its lower edge immersed in the water. The casing 15 houses steam-supply piping 16 controlled by valves 17. A pair of hollow pillars 18 upstand from opposite sides of the casing 15, the lower portions thereof being closed at 19 so that steam pipes 20 may be connected thereto for supplying steam to the piping 16. The upper parts of the pillars 18a constitute guide rods for a pair of hollow tubes 21 between which is connected a cross-piece 22 supporting a hydraulic jack 23, the piston 24 of which is connected to a pressure plate 25 located in the container.  The pressure plate 25 is hollow with a square base 26 and triangular sides 27, and by operation of the jack 23 may be forced into the container 10 to exert pressure on the mixture 28.  Springs 29 assist in the return of the pressure plate.  To raise the plate and jack, the cross-piece 22 is connected by a cable 30 to a counter-weight 31, the jack and the pressure plate being kept in the lowered position by stops 32 inserted in holes 33 in the pillars, and the hollow tubes 21 contacting with the stops.  A hinged side 15a of the casing enables the wax to be removed from the surface of the water bath and a hinged side 10a of the container enables the feathers to be removed.  In operation the steam is turned on and the wax passes through the perforations on to the water bath.  After about 5 minutes, the steam is turned off and the jack operated to exert pressure on the mixture of wax and feathers to expel more wax. The process is then repeated and the dewaxed feathers are removed from the container.

Abstract: 1,090,444. Electrostatic precipitators. W. KAUFMANN. Feb. 1, 1966 [Feb. 3, 1965], No. 4363/66. Addition to 985720. Heading B2J. The electrostatic precipitator of the parent Specification is modified in that the discharge electrodes have a plurality of lateral projections, the height and spacing of which are so related to the diameter of the opening in, and the length of, the ring-shaped cleaning elements that the cleaning elements oscillate as they slide along the discharge electrodes thereby improving the cleaning effect. In Figs. 1 and 2 the discharge electrode 1 is in the form of a corrugated wire, the depth and the pitch of the corrugations being so related to the length and to the diameter of the opening of the cleaning element 2 that oscillation of the element takes place, the element thereby impinging on the electrode and causing it to vibrate. More than one ring - shaped cleaning element may be used per electrode. In a modification, the discharge electrode is helical in construction and may be made to vibrate. The central opening of the cleaning element in this case may be eccentric or non- circular in construction. In a further modification, the cleaning element consists of two wire rings held at an axial distance from each other. Instead of the lateral projections being formed by the corrugated or helical shape of the electrode, the latter may be constructed as a barbed wire or may consist of a strip of sheet metal folded like a bellows and partly extended or in which folds or pockets are made as by stamping.
