Abstract: 997,230. Seaming non-metallic sheet material. PNEUMATIC SCALE CORPORATION Ltd. Dec. 27, 1961, No. 46322/61. Heading B5K. [Also in Division B8] Apparatus for trimming and sealing the mouth portion of a plastics bag comprises continuously moving means for gripping and closing the opposed walls of the mouth portion adjacent its marginal edge, and a heated element spaced from the gripping means to simultaneously trim the edge and seal the bag by fusion together of the opposed walls. In one embodiment, plastics bags 12, which may contain an article of clothing 11 (Fig. 20), are advanced along a conveyer 10 past a guide member 26 (Fig. 1), to belts 16, 18, e.g. of leather which are mounted on pulleys 28, 30 and smooth out and flatten the mouth portions 14 of the bags before they are presented between metal belts 20, 22 driven by pulleys 104, 108 and arranged preferably at right angles to each other as shown in Fig. 11. While gripped solely by the metal belts, the mouth portion 14 of each bag engages a heated wire 24 arranged at between one and three degrees to the horizontal to trim and seal by fusion the mouth portion. The pulleys 104, 108 and belts 20, 22 are cleaned of surplus plastics material by heated members 190, 192. A mechanism for detecting whether a part of the bag contents is caught between the metal belts 20, 22 comprises a needle 302 (Fig. 20) which stops the machine when engaged by the upper belt 20. To ensure that the closure is positioned centrally of the thickness of the bag, the belts 16, 18 are carried by a bracket 52 vertically adjustable by means of a hand wheel 82 (Fig. 3). The metal belts 20, 22 may be moved to give edge-to-edge or edge-to face contact thereof to deflect the mouth portion up or down as desired by adjustment of brackets 115 carrying the pulley shafts 112, 114 and attached to a slide wall 116 of frame 118. The latter may be adjustably rocked in a shaft 152 by rotation of a hand-wheel 166 operably connected to spaced ears 158 on the frame to adjust the position of bag mouth engagement according to the contents thickness, and the wire 24 is mounted on brackets on the frame to be adjustable with the belts.

Abstract: 1,131,237. Photographically producing printing plates. UNION CARBIDE CORP. Nov.9, 1965 [Nov.9, 1964], No.47538/65. Headings G2C and G2M. Bi-metallic printing plates are produced by photo-sensitizing a membrane of an association product of a phenolic resin and an ethylene oxide polymer which has been rendered insoluble in organic solvents, imagewise exposing the membrane to render the exposed areas water-insoluble, applying an aqeous solution of a hydrophobic metal salt to the membrane which is either (i) reduced to the metal and deposited on to a hydrophilic metal support on which the membrane is coated or (ii) contacting the membrane with such a support and reducing the metal salt, so that the metal is deposited on the support. Specified hydrophilic metal supports are aluminium, chromium, zinc, nickel, lead, magnesium and steel and specified hydrophobic metal salts are salts of copper, silver or gold. The phenolic resin may be a resole or a novolak resin and is sensitized with a haloalkalane such as iodoform. The reduction of the metal salt may be performed chemically or electrolytically. In the examples, paper is coated with the association product, baked to insolubilize it and then photo-sensitized with iodoform. The material is then imagewise exposed and soaked in aqeous methanol and then in copper sulphate solution. It is then contacted with a steel plate and a positive copper image is deposited thereon by chemical reduction. Alternatively, the association product may be coated on a steel plate, baked, sensitized, exposed and treated with a copper salt as above which is then chemically or electrolytically reduced to a positive copper image. If a continuous tone transparency is used in exposure step, continuous tone plates are produced.

Abstract: 475,858. Autographic recorders. LAMSON PARAGON SUPPLY CO., Ltd., and GARWOOD. V. W. May 14, 1937, No. 13661. [Class 106 (i)] In an autographic recorder having a cashdrawer released by the operating mechanism, the arrangement is such that if the record strips are restrained during the rotation of the operating shaft, the operating mechanism and drawer release mechanism become locked and can only be freed by use of a key whereby access may be gained to such mechanism. Frictionally mounted on the hub of one of the usual feed rollers 10 is a disc 16 that also bears on the strip and is pin-and-slot connected to a lever 21 pivoted on the feed roller. If the strips are arrested during the rotation of the feed rollers, the disc 16 is also arrested and the consequent relative movement between the disc and roller rocks the lever 21 clockwise to cause its arm 24 to abut a stop 26, or one of a series of such stops, and thus lock the operating-means. The cash-drawer 3, which is normally released at the end of the operation, is thus held closed. Operation of the machine is prevented, while the drawer is open, by a hooked lever 37 that intercepts a stud 38 on the feed roller. The closing of the drawer disables the lever through lever 31 and link 34. The operating-means, after having been locked by either of the levers 21, 37 may only be released by some person having a key giving access to the interior of the casing, whereby he is enabled inanually to disable a non- return pawl 14 and reset the mechanism.
