Title: Apparatus for binding bundles of sheets
IPC: B65B27/08
Filed: 1974-07-22
Abstract: 1464987 Binding GLORY KOGYO KK 22 July 1974 [23 July 1973 7 June 1974] 32301/74 Heading B8C Apparatus for binding a stack of sheets 3 into a bundle comprises a casing, rotatable sheet holding means 5, means 13 for supplying a tape 10 having a thermoplastic adhesive layer, means 16 for inserting the leading end of the tape 10 into the stack 3, drive means for the holder 5 and tape bonding means 17 for fastening the tape 10 around the bundle. The holding means 5 is driven by motor M acting through a gear train 34, 35, 39, 21, clutch 37 and brake 38, a further gear train 41-44, 46 driving a shaft 45 bearing timing cams C 1 -C 6  for synchronizing operation of the means 13, 16, 17, the latter cam C 6  controlling operation of the clutch 37 and brake 38 to control rotation of the holder 5. On pushing a stack 3 between plates 4 defining the holder 5, a rod 64, Fig. 3, is engaged and depressed within a shaft 20, actuating a switch S to start the motor M. Rotation of the cam C 1 , Fig. 5, causes a lever 49 to pivot about a pin 48, motion being transmitted through a linkage 50, 51, 54, 56, 63 including pressure regulating means 40, to the shaft 20. A member 32 on the shaft 20 acts against followers 31, Fig. 3, to urge the plates 4 together against a spring 33, thus gripping the stack 3. The holder 5 is then rotated to position the sheets horizontally, and a finger 15 of the insertion means 16, Fig. 7, is advanced on a rail 81 by means of a lever 88 under the action of the cam C 5 , so that the stack 3 is opened up. A plate 14, Fig. 8, is then pushed into the opening under the control of the cam C 4  by pivotal movement of a spring-biased lever 96. The leading end of the tape 10 is drawn into the stack by the plate 14, whereupon the finger 15 is retracted followed by the plate 14, to leave the tape 10 gripped by the stack 3. The holder 5 is then further rotated to wind the tape 10 around the stack 3, and the bonding means 17 is raised under the control of the cam C 2  and levers 122, 123, 117, Fig. 11, so that a heated pad 118 contacts a limited area of the tape 10, Fig. 12 (not shown) to form a preliminary adhesive bond to retain the loop formed around the stack 3. The cam C 3  next actuates a spring-loaded lever 112, Fig. 9, to cause a cutting blade 105 and slotted arm 103 to co-operate, thus cutting off the loop of tape 10, and the bonding means 17 is finally actuated once more to adhere the loose tape end to the rest of the loop. The stack 3 may then be withdrawn, the plates 4 of the holding means 5, of thin resilient sheet metal, sliding out from under the tape 10.

Title: Improved process for preparing dicyclopentadiene dicarboxylic acids and salts thereof
IPC: C07C51/15
Filed: 1954-11-09
Abstract: Alkali metal salts of dicyclopentadiene dicarboxylic acids are prepared by feeding an alkali metal cyclopentadienyl into an inert liquid hydrocarbon containing an excess of dissolved carbon dioxide. The free acid may be obtained from the salt by treatment with dilute mineral acids.  The reaction may be carried out at temperatures between -50 DEG  and +250 DEG  C.  The alkali metal, i.e. sodium, potassium or lithium, used in the preparation of the cyclopentadienyl is preferably in the form of a fine dispersion, wherein the particles have an average particle size of less than 50 microns, in an inert hydrocarbon which is reacted with the cylcopentadiene in the presence of an alcohol activator such as methanol, ethanol or isopropanol. Specified hydrocarbons which may be used for the alkali metal dispersion or the solution of carbon dioxide are benzene, toluene, xylene, hexane, heptane and light naphthas.  Specified starting materials are cyclopentadiene, methyl cyclopentadiene and mixtures thereof which may contain diluent paraffin and aromatic hydrocarbons. The acids or derivatives thereof may be used in alkyd resins or polyester lubricants or as solvents or plasticisers.  The invention is illustrated by a series of runs in which a slurry of cyclopentadienyl sodium in xylene is fed intermittently into a stainless steel turbo-mixer containing xylene saturated with carbon dioxide under various pressures, the temperature of the reaction mixture being between 20 DEG  and 44 DEG  C.  The results are given in a table and are compared with results obtained by the known process of adding carbon dioxide under pressure to a slurry of cyclopentadienyl sodium.

Abstract: 998,409. Window blinds. HUNTER DOUGLAS INTERNATIONAL (QUEBEC) Ltd. Sept. 8, 1961, No. 32406/61. Heading A4B. A flexible screen 10 of gauze-like fibreglass is secured at one end to a spring- loaded roller, has its sides guided in edge tracks 11, and is provided at its free end with a rail 20 having catch means adapted, when the rail is brought to the closed position and in urged in one direction away from the plane of the opening to be screened, to engage co-operating catch means fixed to an edge of the opening, movement of the rail in the opposite direction away from the plane of the opening causing the catch means to become disengaged. As shown, the rail 20 may have at each end a plate 32 slidable in the channel formed by the front and rear flanges 14, 16 of the edge track 11, the plate having a slot 41 which engages a tongue 40 fixed to the edge track. When the screen is brought to the closed position a resilient sealing strip 28 of arcuate cross-section on the bottom of the rail is pressed against the sill 29; the curvature of the strip 28 causes the rail to be urged forwardly so that the lower edge of the slot 41 engages beneath the tongue 40. The lower portion of the flange 16 of the edge track is bent slightly at 43 so as to widen the bottom of the guide channel; this allows the rail 20 to pivot rearwardly above its upper edge when upward pressure is applied to the operating bar 23, thus disengaging the slot from the tongue. In a modification the slot 41 is replaced by a lug or tongue for engagement with the tongue 40. In other embodiments, the slide plates 32 are omitted, the catch means comprising apertures in the rail for engaging lugs or hooks -on the sill, or a continuous longitudinal hook-type flange on the rail for engagement with an opposed hook-type strip on the sill. The screen may be mounted with the roller at the upper or lower end or a side edge of the opening. Specification 998,408 is referred to.
