Abstract: 1,018,515. Seaming non-metallic sheet material; laminates. O.-B. RASMUSSEN. July 20, 1964 [May 22, 1963], No. 20338/63. Headings B5K and B5N. A laminate of films of cross-laminated thermoplastic material is seamed by placing the films 5, 6 on top of one another, punching a series of holes 7 through the layers along the desired seam, applying on each side of the laminate thermoplastic material over the holes 7, and causing this thermoplastic material from each side to unite within the holes 7 while embracing each side of the laminate without bonding to the sides of the laminate. Each of the films 5, 6 comprises two plies of high density polyethylene oriented by stretching and which is laminated so that the directions of orientation of the two plies form an angle with one another. The holes 7 may be punched in a curved or straight line and are preferably circular. Molten thermoplastic material, preferably polyvinyl chloride, may be extruded upon or rolled on to each side of the films 5, 6 and solidifies to form knobs or caps 8, 9 connected at 10 through the holes 7. In an alternative embodiment, Fig. 2 (not shown), continuous strips 11, 12 are placed on each side of the films 5, 6 and are united by highfrequency or ultrasonic welding located at the holes 7. In a third embodiment, Fig. 3 (not shown), a single strip 13 is folded around the edges of the two films to be united and welding performed through the holes 7. The invention is applicable to forming a bottom seam on flattened tubular bags.

Abstract: 632,534. Electric cables. HOLMES, E. P. July 28, 1947, No. 20357. [Class 36] In order to protect the paper insulation 2 from the heat produced when a cable is provided with a sheath 6 of extruded copper, aluminium, or other high melting point metal, a heatprotective layer of metal 3 is provided to cover the insulation and an air space is left between the layer 3 and the sheath 6. The layer 3 may consist of a wound tape of metal or metallized paper or cellulosic material. Aluminium foil backed with paper may be used. The surface of the metal may be bright to provide good heat reflecting qualities. As shown in Fig. 2, the metal foil 3 may be crinkled or otherwise formed with projections 4 to separate it from the sheath and form air-spaces 5. The sheath may alternatively be separated from the foil 3 by a helical winding of asbestos cord. Fig. 4 shows a modification in which the paper-backed aluminium foil 8 is covered with cotton tape 9 having entwined metal strands which make contact with the sheath 6. The tape may become charred when the sheath is extruded but the insulation within the foil 8 is unaffected. The overlapping turns of the tape maintain airspaces 5. Fig. 5 shows a further modification in which the protective layer consists of a wound tape comprising a cellulosic layer 11 and a layer 10 of aluminium foil, one edge of the compound tape being folded over as shown at 12 to form air-spaces 5.

Title: Improvements in or relating to processes for preparing monochloroacetic acid and aryloxyacetic acid compounds and the compounds resulting from said processes
IPC: C07C205/37
Filed: 1950-08-17
Abstract: Monochloracetic acid is prepared by chlorinating a mixture of 15-75 per cent glacial acetic acid and 85-25 per cent acetic anhydride at 70-110 DEG  C.  Using approximately one molar proportion of chlorine, a product containing small amounts of chloracetyl chloride and chloracetic anhydride is obtained which on hydrolysis with sufficient water, generally 1-3 per cent by weight of the product, preferably at about 60-150 DEG  C., yields monochloracetic acid having a crystallizing point above 59 DEG  C.  The product may be used directly for the production of aryloxy derivatives by reaction with hydroxyaryl compounds and an aqueous base, for example at about 50-100 DEG  C.  The chlorination is preferably initiated at about 95-110 DEG  C., and a 5-10 per cent excess of chlorine is used. Reaction of the product with a phenol and alkali or alkaline earth hydroxide or alkali carbonate gives a salt of the phenoxyacetic acid which may be converted to the free acid or other salts or to alkyl esters.  Phenols specified include chlor, brom, iodo, fluoro, nitro, alkyl, alkoxy, and aryl phenols or naphthols.  Examples describe the chlorination of mixtures containing various proportions of acetic acid and anhydride, hydrolysis of impurities by heating with water or reaction of the crude products with 2,4-dichlor- or 2,4,5-trichlor-phenol, p-chlor-o-cresol, o-chlorphenol or b -naphthol.  The reaction product with phenol and caustic potash is converted to phenoxyacetic acid which is esterified to give methyl phenoxyacetate.  The crude chloracetic acid is also neutralized with caustic soda, sodium cyanide added at 50-60 DEG  C., and cyanoacetic acid recovered.

Title: Case packing machine
IPC: B65B5/06
Filed: 1959-06-17
Abstract: 873,342. Case packing machines. FOOD MACHINERY & CHEMICAL CORPORATION. June 17, 1959 [Aug. 20, 1958], No. 20768/59. Class 94(1). A machine for packing articles, such as cans, into a case, comprises a collecting platform 30, Fig. 9, on which the cans are assembled in parallel lanes 135a/135b between a plurality of removable guide members 100a to 100e and means whereby on the complete number of cans having been assembled the guide members 100a to 100e are withdrawn and a reciprocating pusher member displaces the cans transversely of said lanes through a shoot and into the case. As shown the guide members 100a to 100e are semi-cylindrical guide bars housed in semi-cylindrical grooves in the platform 30 whereby, on rotation, their flat faces may be flush with the platform, Fig. 10, to permit the cans to be pushed thereacross, or they may project up from the platform 30, Fig. 9, to define the lanes 135a to 135d. The cans are moved into the machine on a continuously moving conveyer belt 51, Fig. 1, between parallel guide plates 65a to 65e and thence across a ramp on to the platform 30. A case (such as A in Fig. 1) is arranged with its open mouth embracing the four sides of a shoot 40, whereupon the lower flap of the case adjacent the open end thereof engages a switch 320 to start a packing cycle. In this cycle a support plate 290 is raised into a horizontal position to support the case A. A reciprocating pusher 35 then descends and pushes the assembled cans off the platform 30 and through the shoot 40 into the container A which is then lowered by the arm 290 to the position shown. Thereafter a toothed member 117 causes all the guide bars 100a to 100e to pivot to their upstanding position, a member carrying can sensing fingers 140a to 140d is moved from a retracted position to a can sensing position, and some stop members projecting up through the ramp between the conveyer 51 and the platform 30 are moved sideways from a can engaging position to a position aligned with the guide plates 65b to 65e. The pusher plate 35 is also raised and withdrawn to its rearward position. As the cans from the conveyer belt 51 push each other on to the platform 30 the leading can in each lane eventually contacts a corresponding spring-biased can sensing finger 140a to 140b and when these fingers have all been depressed by a leading can the can stop members between the platform 30 and the conveyer 51 are once again moved into the path of the incoming cans. A support bar 144 carrying the can sensing fingers 140a to 140d then moves away from the cans on the plate 30 to provide a clear path for the pusher member 35 when the next empty case is applied to the shoot 40.

Title: Improvements in or relating to photographic reproduction in colour
IPC: G03C7/30
Filed: 1938-07-14
Abstract: ,516,937. Colour photography BUTEMENT, C., and DUFAY - CHROMEX, Ltd. July 14, 1938. No. 20952. [Class 98 (ii)] Multicolour photographs are produced by (a) exposing to the object a support bearing two silver halide layers to produce red and green colour separation records; (b) exposing simultaneously a single support bearing a single layer to produce the third colour record and developing this to produce a record in yellow; (c) developing the two layer material and exposing the residual silver halide in one layer by light to which that in the other layer is insensitive; (d) developing the exposed layer to the appropriate colour, i.e., magenta or bluegreen and exposing the residual silver halide in the remaining layer; (e) developing this to blue-green or magenta and removing the silver from both layers; (f) superimposing the resulting two colour record on the yellow record. Preferably the support of the two layer material is transparent and the second exposure is effected through this. In an example a celluloid support carries red and green sensitive layers and is printed under a multicolour screen transfering, a magenta filter being provided between the layers if the red sensitive layer is also sensitive to green. A yellow filter is used during the exposure. The material is then developed and the red-sensitive layer fogged by exposure to red light e.g. from a cadmiummercury vapour discharge lamp and the residual silver developed to blue-green with a-naphthol and diethyl-p-phenylene-diamine. The green layer is then fogged by green light e.g. from a mecury vapour discharge lamp or by white light and developed to magenta with p-nitrobenzyl cyanide and diethyl-p-phenylene-diamine. The silver from both layers is then removed with Farmer's reducer. The yellow record is prepared by exposing bromide paper to blue light under the transparency reversing the image andtoning it yellow or employing a yellow colour developer, e.g., actoacetanilide and diethyl-pphenylene-diamine, as the second developer in the reversal process. The records are then superimposed in register. If the two layer material is on an opaque support this is stripped .off after superimposition. Specification 486,424 is referred to.
