Abstract: 1460743 Packaging products in sleeves JA CANNINGS Ltd 18 Nov 1974 [6 Dec 1973] 56681/73 Heading B8C Packaging apparatus for loading a product 30 into a sleeve 32 comprises a carriage 22 adapted to receive the sleeve and the product end-to-end, means for transporting the carriage from a loading station 24, where it receives the sleeve 32 and the product 30, to a discharge station 26 where the package, comprising the product within the sleeve, is discharged, a mechanism 44, 46, 54, 60 on the carriage 22 adapted to align the product 30 with the open end of the sleeve 32 and to advance the product into the sleeve, and operating means 70, 76 located between the loading and discharge stations so that the product is aligned with, and loaded into, the sleeve as the carriage moves between the stations 24, 26. A plurality of carriages 22, each comprising a base plate 28, is carried, in succession, from the loading station 24, to the discharge station 26, by two parallel endless chains (16), Fig. 1, not shown, a high pressure jet acting upon the package at the discharge station 26 to move the package sideways on to a take-out conveyer, not shown. Each carriage 22 has a fixed wall 40 which carries an arm with a soft foam pad 36 to pick-up the lowermost product in a hopper, not shown, and a pair of elements 38 which are raised to pick off the lowermost of a stack of flattened sleeves in a magazine, not shown, the product and the sleeve both being deposited on to the base plate 28 at the station 24 as the carriage moves in the direction X, Fig. 4, and a cam follower 58, Fig. 2, on a spring-loaded bell-crank and slide mechanism 56, 46, engages a cam 70, Fig. 4, to move a wall 44 away from the wall 40. When the wheel 58 leaves the cam element 70 the bar 44 moves back towards the wall 40 so that the flat sleeve is erected and the product is aligned with the open sleeve. Continued movement of the carriage 22 in the direction X causes a ramp section 86 to push the erected sleeve beneath a bridge 42 from which jets of compressed air issue to open fully the erected sleeve. Simultaneously, a cam follower wheel 64 rides along the section 76 of a cam element 74 to move a bar 60, Fig. 2, in the direction of a slot 62 and advance the product fully into the sleeve. As the follower wheel 58 moves along a cam section 72 the bar 44 is withdrawn slightly in a direction away from the wall 40 to release the grip upon the package so that the latter is ready for discharge, the follower wheel 64 moving along the cam section 78 to retract the bar 60.

[Also in Division F1] An hydraulic variable speed gear comprises a pump (or motor) 15 on an input shaft 11 and having a rotor 16 carrying sliding vanes 17 spring-biased against the inner cylindrical surface 18 of a stator 19, and an enclosing motor (or pump) 24 on an output shaft 13 and having a rotor carrying vanes 21 spring-biased against the outer cylindrical surface 20 of the stator 19, the transmission ratio being varied by moving the stator radially to vary the spacings between the shaft axes 11, 13 and the cylindrical surfaces 18, 20, respectively. As shown, the shafts 11, 13 are parallel but not concentric, the surfaces 18 and 20 are concentric, and the stator 19 is moved laterally by rods 27 mounted in endcheeks 25, 26 fast with the stator. Again, the surfaces 18, 20 may be eccentric, and the shafts 11, 13 concentric. The vanes 17, 21 may be inclined so that they trail and reduce friction, or they may be located in a cage to reduce radial loading. The stator is movable between two end positions in which the surfaces 18, 20 are respectively concentric with the pump 15 and motor 24, the respective shaft being freerunning. A known valve (not further described), connecting the reservoir 10 with a duct 30 communicating between the pump and motor, may be included in the gear so that on opening the valve in either of the two end positions, both shafts will be free running.

Abstract: 1376694 Cameras SEIKO KOKI KK 19 Dec 1972 [21 Dec 1971] 58554/72 Heading G2A A shutter mechanism comprises an electromagnet 68 which when energized causes a photoelectrically timed daylight exposure to be made and when not energized causes a mechanically timed, flash exposure to be made. Energizing of the electromagnet may be controlled according to the level of subject brightness or according to whether or not a flash-bulb has been inserted. As shown, for high subject brightness a photoelectric element 61 and transistor switch 66, 67 cause electromagnet 68 to be energized and hold members 10, 11, 15 in the positions shown. Release 2 moves a lever 27 so that a lever 24 can rotate to strike a shutter operating member 18 and to open a timing switch S4. Member 18 is stopped by a projection 15b and held by a latch 20 until electromagnet 68 is de-energized by the charging of a capacitor 62 whereupon member 10 is released to remove latch 20. For low subject brightness, electromagnet 68 is de-energized and projection 15b and latch 20 are rotated out of the path of shutter operating member 18. Member 18 rotates to close flash synch switch S5 and is returned by a spring 17 to effect a mechanically timed exposure. In Fig. 6 (not shown) insertion of a flash-bulb (69) automatically disconnects the electromagnet (68) from the battery (60). Removal of the bulb disconnects the flash circuit and energizes the electromagnet.

A strip of foil, e.g. Al, Ni, Cu or Fe, is fed from a coil 11 through a seal 12 to a chamber 13 where it passes over a water-cooled roll 14 in an inert atmosphere. The foil 10 is sprayed with a molten superalloy, e.g. Fe, Ni or Co alloys, from a plasma gun 16 or any other metallizing gun, supplied with powdered alloy from hopper 17. The molten alloy solidifies on the foil and the resulting composite is passed between rolls 18 to consolidate the strip 15. The operation may be repeated in order to produce strip of greater thickness. The foil 10 can be removed from the strip by passing the composite through an etching solution to dissolve it away from the strip 15 after cold rolling.
