Title: Improvements in or relating to laminates
Inventor: GATES WILLIAM ELLIOTT FREW
IPC: B32B27/00
Filed: 1961-03-13
Abstract: 953,663. Laminates. IMPERIAL CHEMICAL INDUSTRIES Ltd. Feb. 26, 1962 [March 13, 1961], No. 9041/61. Heading B5N. A laminate consists of a film of isotactic polypropylene, or a mixture of isotactic polypropylene with a small proportion of polythene, bonded to a film of polyethylene terephthalate. The laminate may be made by extruding a melt of polythene, preferably having a density below 0.93, on to one side of one of the films and pressing the other film against the coated surface. Alternatively other adhesives and/or primer or anchor coats as listed below may be used. The polypropylene film may be pretreated by corona discharge or with ozone, ionizing radiation, flame, or chromic acid in sulphuric acid, to produce superficial oxidation. Either or both films may be unoriented, oriented, or oriented and heat set. The polyethylene terephthalate film may be pre-metallized, preferably on the bonded surface, and care is preferably taken to avoid crystallization of the film. Alternative adhesives usable are solutions of atactic polypropylene in toluene, petroleum ether or other hydrocarbon, solutions of chlorsulphonated polythene, cyclized rubber, vinylidene chloride copolymers, polyvinyl acetate nitrocellulose, rubber, nylon-8, polyethylene terephthalate/sebacate, or butadiene acrylonitrile resins. Primer or anchor coats such as a syrup of melamine-formaldehyde or thermosetting resins such as butylated urea-formaldehyde resin may be used on the polypropylene film, or an alkyl titanate, e.g. tetrabutyl titanate on the polyethylene terephthalate film. Other primer or anchor coats usable are N-alkoxy methyl polyamides, and phenol-, urea-, or melamine-formaldehyde resins. A biaxially oriented polyethylene terephthalate film treated with a primer or anchoring coat may be laminated with a polypropylene film by extruding the latter molten on to the treated film and cooling immediately, as by passing through the nip of cold steel, and silicone rubber faced, rollers, with the polypropylene film in contact with the steel roller. Solutions of static polypropylene used as adhesive may contain carbon black. The products may be used for packaging, the polyethylene terephthalate film being less gas-permeable and, when oriented and heat-set, less shrinkable on heating, than the polypropylene film, but the latter being more readily heat-sealable. Sealed packages may be sterilized at temperatures up to 150‹ C. The inventions claimed in the following Specifications are disclaimed: 868,159. 891,417, 909,947 and 913,289, Specification 715,914 also is referred to.

Title: Improvements in or relating to locomotive axle-box guides
IPC: B61F15/04
Filed: 1923-04-03
Abstract: 209,649. Rawdon, E. W., and Roberts, E. M. April 3, 1923. Axle-bearing guiding arrangements have a wedge interposed between the axle-box body and the horn plate adapted to be adjusted to take up forward and rear play of the axle-box body by means of a ratchet and a pawl or pawls carried by a sliding block. The wedge 14, between the horn plate 11 and axle-box 10, is recessed at 16 to take the head of the bolt 17, the bolt being screwed through the brace member 12. A ratchet wheel 20 is bored to receive the bolt 17 and operates it through feathers working in featherways 19 on the bolt, the ratchet wheel being also provided with a base flange slidably engaged by lugs 23. A yoke member 36 attached to the axle-box straddles a box 25 attached to the brace member 12, one side of the box, Fig. 3. being cut away to permit pawls 32, pivoted at 33 to a sliding block 30, to engage the teeth of the ratchet wheel 20. A square-shanked bolt 39 passes through the block 30 and works in horizontal slots 38 in the box 25, the ends of the bolt also passing through vertical slots in the yoke piece 36. Vertical play of the axle-box does not operate the pawls due to the sliding motion in the slot 37, but pounding or horizontal motion of the axle-box reciprocates the sliding block 30, enabling the pawls 32 to turn the ratchet wheel 20 to tighten the wedge 14. The pawls 32 consist of a number of hook-shaped plates each controlled by a separate spring 35 and each slightly longer than the other, this ensures that one pawl is always in engagement with a tooth of the ratchet wheel and permits fine adjustment to be made. The head of the bolt 17 may be dispensed with, the end being threaded to the opposite hand of the existing thread and engaged by a nut housed in the recess 16.

Abstract: 623,604. Mounting cap bars &c. in spinning &c. machines. CASABLANCAS HIGH DRAFT CO., Ltd., and NOGUERA, J. April 8, 1947, No. 9349. [Classes 120 (i) and 120 (ii)] In a means for detachably mounting cap bar rods carrying three cap bars 2 and an end cap bar 2a on back roller slides 3 of a textile spinning or preparing machine, the slides 3 are provided with rearwardly extending portions 4 having a cavity 5 in one side and an open ended groove 6 in the opposite side. The cavity 5 receives one end 1b of a cap bar rod 1 and the end la of the next adjacent cap bar rod engages in the groove 6. The end 1a of each rod 1 is attached by a set screw 7a in an aperture in one arm 7 of a double-armed depending portion of the end cap bar 2a in such a manner that the end 1a protrudes through the arm. The other arm 8 is provided with an open ended slot 9. The design is such that the cap bar 2a and the slide extension 4 can be mutually engaged by sliding end 1a of the rod into groove 6 and the slot 9 over the next adjacent cap bar rod 1 the end 1b of which is supported in the cavity 5. The arms 7 and 8 then embrace the slide extension 4. The cap bar 2a can then be rotated with the attached rod 1 into the operative position or into the open position (shown in full and chain-dotted line respectively in Fig. 2). The cap bar rod 1 is thus retained in the groove 6 for all angular positions except the engaging and disengaging position.
