Abstract: 1,059,712. X-ray film cassettes. GENERAL ANILINE & FILM CORPORATION. Jan. 22, 1965 [Jan. 24, 1964], No. 2908/65. Heading H5R. A cassette carries radiographic sheet material in a film holder clamped inside the cassette frame and is unloaded automatically by insertion of the cassette into a film processing machine which frees. the film sheet for removal. The cassette comprises a rectangular frame 1 with flangedover edges 2a, 2b, 2c on three sides, the channel-shaped flanges on two sides having welded inside spacing strips 4a, 4b, and 5a, 5b to provide a location for the X-ray transparent cover plate 3 and the film sandwich A-F. The latter is made up of two elements, hinged together by means of a slot in the upper element and tab 39 on the lower one, and effectively biased apart by this and a slight curvature of the lower element. The upper element comprises a top plate A of aluminium, a layer E of chipboard and a fluorescent intensifying screen F, and the lower element, a bottom plate B of stainless steel and a padding C of velveteen, the film emulsion being contained between the two elements. The bottom plate B carries on its underside a number of pressure pads (8a-8e), having bevelled edges, which abut against similar ones 7a-7e on the base 1 of the cassette when the film sandwich is inserted into the cassette, such that a pad (8) slides up over the corresponding one 7 pressing together the upper and lower elements of the sandwich and thus clamping the film emulsion between them and into firm engagement with the intensifying screen. After exposure of the film, the cassette is inserted into a light-tight opening in the front of the processing machine (Figs. 3-5, not shown). The cassette is provided with a lever 28 having a lug 19 which engages a fixed stop inside the processing machine. As the cassette is advanced, the lever rotates about its supporting pivot 29 and its other end drags forward an arm 30, having a lug 40 which abuts the end of the film sandwich further inside the cassette such that the film sandwich is pushed forward into the processing machine until the pads (8) slide down off those 7, freeing the film, and the sandwich elements abut the rollers (12, 12a). The film is caught by the rotating rollers and extracted for processing.

Abstract: 979, 078. Web coating apparatus. RESEARCH LABORATORIES OF AUSTRALIA Ltd. Jan. 26, 1962 [Feb. 3, 1961], No. 3146/62. Heading D1L. [Also in Divisions B2 and G2] A machine for applying developer to paper comprises a base, means on the base to feed paper forward at a regulated speed, an applicator roller supported in bearings on the base immediately beneath the plane in which the paper moves, means to feed developer to said roller and means to rotate said roller to cause the surface thereof adjacent to the paper to move in the same direction as the paper but at a greater linear speed whereby a liquid wedge is built up between the roller and the paper while urging the paper forward. In the embodiment shown a base 1 carries a tank 3 of coating liquid 6 and a coating roller 5 dips into said tank to pick up the liquid and transfer it to material e.g. paper 41. In front of roller 5 a pair of feed rollers 18, 19 are provided for feeding the material to the coating roller 5. The rollers 18 and 5 are belt driven and the arrangement is such that the peripheral speed of the coating roller 5 is substantially higher than that of the feed roller so that a wedge 40 of coating liquid builds up between the roller 5 and the material 41. An adjustable guide bar 45 is provided to deflect the material downwardly just sufficient to have correct contact pressure with the film of coating liquid. This bar also acts to prevent the wedge of coating liquid spilling over the rear edge of the material as it passes through. The bar 45 may be replaced by a roller. A pair of auxiliary feed rollers may be positioned after the coating roller 5 and an agitator 9 is preferably provided in the tank 3 to keep the coating liquid mixed.

Title: A device for orientating cylindrical objects on a conveyor
Inventor: RAFFE JOSEPH PETER
IPC: B65G47/244
Filed: 1958-01-30
Abstract: 844,798. Conveyers. CHISWICK PRODUCTS Ltd. Jan. 26, 1959 [Jan. 30, 1958], No. 3173/58. Class 78 ( 1 ). Cylindrical objects, such as lidded tins 2 having an opening-lever 3, are uniformly orientated whilst being conveyed on an endlessbelt 1, by a device mounted astride the belt. This device comprises a stop-member 12 having a part 13 mounted on a pivot 11 and a part 14 pivotally mounted on a bolt 15 on the part 13, and a wheel 30 rotatable on a stub-axle 31 carried by arms 24, 25 which are pivoted at one end on a shaft 23 extending transversely of the belt and at the other end are biased by a spring 32 so as to urge the wheel toward the belt 1. When a tin reaches the device, its leading edge abuts the stop-member 12 which in its normal position will prevent further forward movement of the tin since the part 14 of the stop is prevented from swinging by a member 19 having a part 20 extending across the conveyer into the path of movement of the part 14. At the same time, the wheel 30 presses down on one side of the tin and this off-centre pressure, together with the forward movement of the belt, effects rotation of the tin until the edge of the opening lever 3 strikes a roller 17 on the part 14 of the stop 12 and pivots the stop about its pivot 11 clear of the retaining-member 19. The tin then pivots the lower part 14 of the stop about the bolt 15 out of its path and is conveyed forward by the belt. In a modification an index may be provided on the container capable of actuating the stop-member release by means of a photo-electric cell. The stopmember may be magnetically held in its normal position and released by a trip-mechanism acting on the object. In a further modification the object may be rotated whilst it abuts the stop-member by endless parallel bands which engage on each side of the object and which are driven in opposite directions. More than one device can be used side-by-side on a single conveyer. The device may be used on a rotary table conveyer.

Feb. 1, 1934, No. 3400. Addition to 392,811. [Class 8 (i)] [See also Group XXXV] In an electromagnetically - actuated compressor as claimed in the parent Specification in which the compressor piston 4 is supported by a mass 3 and forms with springs 2 an oscillatory system having a natural frequency equal to that of the alternating field of the electromagnet 1, the supply of energy to the oscillatory system is controlled by the output pressure of the compressor. The pressure may act on a piston 5, Fig. 4 to oscillate an arm 7 and vary a resistance 8 in the current supply circuit. Alternatively, the arm 7 may be connected to the magnet 1 to vary the air gap between the magnet and mass 3. In a further construction, Fig. 5, the air pressure acts as a piston 5 carried by the mass 3 to vary the frequency of the oscillatory system. The cylinder 9 may in this case be replaced by a clearance space in the compressor cylinder to produce a similar effect. The magnet coil S, Fig. 1, is mounted on the shell h or on a core attached to the shell to facilitate replacement, a bridge i being provided to reduce the leakage field. Eddy currents in the shell are prevented by making it of insulating material, or by dividing it and providing layers of insulating material between the parts. The suction and discharge pipes r, t, of the compressor are formed as springs to support the casing on the base plate p.
