Title: Vinyl Chloride Polymer Compositions and methods for making Open-Cell Vinyl Chloride Polymer Foams
IPC: C08L27/06
Filed: 1968-07-11
Abstract: 1,168,233. Open-cell vinyl chloride polymer foams. GENERAL MOTORS CORP. 11 July, 1968 [2 Aug., 1967], No. 33023/68. Headings C3C, C3P and C3T. A composition comprising a vinyl chloride polymer plastisol and a dispersion of a toluenesoluble siloxane copolymer consisting of R 3 SiO¢ monovalent units and SiO 2  tetravalent units in a ratio of 0À3-0À7, where R is an alkyl or monocyclic aryl hydrocarbon radical (which may be halogenated) is claimed. The composition may be mechanically frothed with air to form a liquid foam which is then heated to fuse the foam into an open-cell foam. In examples the compositions contained vinyl chloride polymer, stabilizers, e.g. complexes of barium, zinc, cadmium, lead, tin and/or calcium salts of fatty acids, plasticizers, e.g. n-octyl n-decyl trimellitate and a copolymer of (CH 3 ) 3 SiO¢ and SiO 2  units.

Title: Machine for splicing and repairing motion picture film
IPC: G03D15/04
Filed: 1945-12-06
Abstract: 618,865. Film splicers. WALLINGSFORD, A. Dec. 6, 1945, No. 33044. Convention date, Dec. 6, 1944. [Class 98 (ii)] A kinematograph film splicer comprises means for holding the ends of the two sections of film in overlapping relation, means for holding transparent adhesive tape to cover the overlapping ends, and means for pressing the tape and film ends together. As shown, two rolls 5 and 6 of adhesive transparent cellulose tape are rotatably supported in a housing 19 towards the rear of the base 1, and the tapes 7 and 8, which leave the housing through the aperture 39, pass with adhesive surfaces facing each other to a cam-shaped device 17 which co-operates with a plate 73 to grip the tapes. Between the housing 19 and the gripping device 17 is arranged an anvil plate 2 located over a well 40 and having (a) pins 43, which engage a pair of perforations in each length of film, the films being arranged to overlap only within the width of the adhesive tapes ; (b) openings 42 in position coinciding with the film perforations ; and (c) slots 41 adjacent the openings 42, the inner edges 45 of said slots being spaced apart by the width of the strip film. Pivoted at the rear end of the base 1, on a rod 10 supported in bosses 66, is a presser member 9 biassed into the position shown by a spring 16. The presser head 11 comprises a fixed plate 12 to which a plate 15 is connected by the heads of countersink screws 55, (Fig. 7, not shown), the two plates being normally held apart by springs. Attached to the plate 12 and extending through channels in the plate 15 are two cutter blades 13 and a punch 14 for each of the holes 42 in the anvil 2. The films are placed in overlapping relation on the anvil on top of the tape 7, and the presser lever is pulled down, whereupon the punches perforate the tapes where they cover the film perforations, and the blades 13 cut-off the tape projecting beyond the edges of the film, the presser head serving to secure the tapes and film lengths. For joining torn films, the ends are not overlapped, but placed in correct relation. In a modification, specially suitable for repairing films carrying a sound track, the ends of the films to be spliced are cut at an angle to the film edges, and in this case the sets, one for each margin of the film, comprising the slots 41, pins 43, and holes 42 on the anvil 2, and the cutter blades 13 and punches 14 in the pressure head 11, have to be suitably staggered relatively to each other.

Abstract: 1,177,871. Boots &c. UNIROYAL Inc. 11 July, 1968, No. 33061/68. Heading A3B. A machine for opening the seam between the two quarters Q<1>, Q<11> of a footwear upper includes a base plate 22 having a slot shaped passageway 25, a splitter 54 located below the slot 25, a hold down 56 above the slot 25 and a pair of guides 35, 36 at the entrance to the slot 25 which can be adjusted either jointly or separately. The base plate 22a, 22b is held by clips 26 on the table 28 of a twin needle sewing machine 16 which sews the opened out edges q<1>, q<11> (Fig. 9) back on to the quarters Q<1>, Q<11>. The quarters are guided into the slot 25 by a spring bar 55a and by guides 35, 36 which are mounted on plungers 33, 34. The plungers 33, 34 are threaded into axially fixed gears 41, 42 which mesh with gears 49, 50 on a shaft 47. In its neutral position (Fig. 1) both sets of gears are in mesh and rotation of the shaft 47 causes the guides 35, 36 to move towards or away from each other. The shaft 47 can also be moved axially (Fig. 4) to disengage either one of the gears so that the guides 35, 36 can be adjusted separately. The splitter 54 has an inverted boat shape with a pointed end 54a and a central rib 54d and opens the edges q<1>, q<11> of the seam as shown in Fig. 9. The hold down 56 is pivoted to a rod at its forward end and is urged downwardly by springs and has two wings 57, 57 which flatten and hold down the quarters Q<1>, Q<11>. After leaving the seam opening machine the quarters pass to the foot 18 of a twin needle 19 sewing machine 16 which stitches the folded back edges q<1>, q<11> to the quarters Q<1>, Q<11>.

Filed: 1962-08-29
Abstract: Monocarboxylic acids, obtained by the reaction of formic acid, or of carbon monoxide and water, either with alkanes in the presence of hydrogen acceptors or with alkenes, are purified by contacting with sulphuric acid of at least 90% by weight concentration, at preferably 10 DEG  to 50 DEG  C. and preferably in an amount between 0.1% and 10% by volume, and subsequently separating the sulphuric acid phase therefrom and optionally washing the raffinate with water or aqueous solutions of alkali or alkaline earth metal citrates, hydroxides, carbonates or bicarbonates.  The carboxylic acid is preferably made in the presence of a catalyst of boron trifluoride and water and optionally also phosphoric acid.  The thus purified product may then be distilled.  In the example, wherein the synthesis of the crude acid from olefins, and carbon monoxide over a H3PO4, BF3, H2O catalyst mixture is described, the storage properties, colour and nickel content of refined and crude acids are compared.
