Abstract: 215,732. Farman, H. et M. May 9, 1923, [Convention date]. Axle distance members and radius rods and torque rods.-The front axle is connected to the frame independently of the springs by pivoted links which act as radius rods and also as torque. rods for the front wheel brakes. In the form shown in Figs. 1 and 2 the links 8, 9 are connected by ball joints 10 to the axle frame 1 and the link 9 is connected to the axle 2 by a ball joint 14, thus serving as a radius rod, while the link 8 is fixed at 13 to the axle and acts both as a radius rod and a torque rod. Laminated springs 4 are pivoted at 5, 6 to the frame and the axle respectively. The rear axle may be provided with similar main springs 4. According to the Specification as open to inspection under Sect. 91 (3) (a) the radius rod's may project forwards from the axle, or they may converge rearwardly and their rear ends may be united and connected to the frame by a single ball joint. In the form shown in Fig. 11 (Cancelled), the axle 2 is guided in a transverse vertical plane by means of links 42, 43 pivoted at their ends to the frame and the axle. The brake reaction is taken up by a rod 44 fixed at the centre of the axle and passing through a transverse slot in a frame member 45, the slot permitting the axle to rock in the aforesaid vertical plane. The main springs are. fixed at the middle to the frame, and one end is connected by a shackle to the axle while the other is free to slide on the flange of the longitudinal frame member. This subject-matter does not appear in the Specification as accepted.
Patent GB-668274-A (GB)
Title: Improvements in or relating to the production of self-supporting films
IPC: B29C43/24
Filed: 1948-04-12
Abstract: <PICT:0668274/IV (a)/1> A molecularly oriented film of a solid ethenoid polymer is obtained by drawing from a molten mass of the polymer a continuous layer of the polymer adherent to a surface continuously moving away from the mass of molten polymer and maintained at a temperature below the melting point of the polymer, subjecting the film-layer to shear during the drawing to orient continuously the molecules of the film in the direction of movement, and continuously stripping the film from the moving surface.  The ethenoid polymer employed is an ethylene homopolymer or copolymer of the formula <FORM:0668274/IV (a)/1> where R1 is hydrogen or alkyl, R2 and R3 are hydrogen or monovalent radicals such as alkyl, phenyl or substituted phenyl, or vinyl, and the ratio x : y exceeds 1 : 5. The film, as it is being formed, may be frictionally passed across an opposing surface which has a temperature above the melting point of the polymer.  The surface of the film in contact with the surface of the carrier band or drum may be smooth or glossy but the other surface is of a somewhat rougher or matt texture and is particularly receptive for adhesives so that the film may readily be laminated with other sheet materials.  The ethenoid polymer may have a molecular weight of 2,500-30,000.  It may be a simple polymer of ethylene or it may be a copolymer of ethylene with one or more organic compounds having double carbon bonds and capable of forming dimers or higher polymers.  The polymer may be compounded with hydrocarbon elastomers such as crude rubber, reclaim rubber, balata, polybutene, polybutadiene, and butadiene and isoprene or styrene copolymers, having molecular weights of 1,000 to 40,000.  The elastomer ingredient may be present in proportions up to 66 per cent by weight of the ethenoid polymer. As shown, the polymer composition is placed at the nip of two calender rolls, the roll A being heated internally to a temperature above the melting-point of the polymer, e.g. 270 DEG  F., and roll B being heated to a temperature below the melting-point, e.g. 190 DEG  F.  Roll A may be stationary or may rotate slowly.  Roll B may rotate 5-30 times faster than roll A.  The solidified film formed on roll B is thus subjected to a frictional drag by roll A and is molecularly oriented.  The upper surface of the film becomes roughened as its is pulled off the roll A.  The film passes round roll B and then round another roll C which is at a lower temperature, e.g. 50-70 DEG  F.  It then passes to take-up roll D. Pigments and dyestuffs may be incorporated in the polymer composition.  Upon the rough or matt surface of the film there may be applied a solvent-, heat-, or pressure-sensitive adhesive coating with or without additional lamin  of woven or unwoven fibrous or non-fibrous sheets, e.g. of cloth, textile fibres, paper, regenerated cellulose, cellulose esters or ethers or polyvinyl compounds. Specifications 471,590, 497,643 and 668,273 are referred to.

Patent GB-1063227-A (GB)
Title: Improvements in or relating to a method of manufacture of twine type yarns from synthetic resins
IPC: D02G3/06
Filed: 1964-03-07
Abstract: Twine type yarns are made by extruding fluent synthetic resin in sheet or tubular form, if the latter, converting the tube into sheet form, and if desired, cutting the sheet into strips or bands, orientating the extruded material longitudinally until it will split over its area and twisting to form a twine type yarn of split sheet, strips or band.  In a modification, an extruded tube is orientated prior to cutting into sheet form.  Specified synthetic resins include polyethylene, polypropylene, polyamides, polyesters and admixtures thereof, polypropylene being preferred. Fibrilation may be assisted if necessary by the action of friction on the material e.g. by brushing.  Orientation may be effected by passing the material through hot air or hot liquid and stretching longitudinally suitably to a draw ratio of 11 to 1. Where polypropylene is used temperatures of 280 to 300 DEG F. for hot air and 245 to 280 DEG F. for hot liquid (e.g. glycol and water) are suitable.  Yarns so made are useful as baler twine, ropes, nets and cordage.

Title: Process for carbon disulphide production
Inventor: FOLKINS HILLIS OTTY
IPC: C01B31/26

Abstract: Carbon disulphide is produced by interacting, in the gaseous state and in the presence of a catalyst, sulphur and a gas composed principally of ethane and/or propane but which also contains methane or an inert gas in a proportion sufficient to prevent the formation of tar, coke and the like.  The inert gas may be nitrogen, carbon disulphide, hydrogen sulphide, or sulphur dioxide.  A hydrocarbon gas which already has the required composition may be employed, or the required composition may be produced from a gas containing hydrocarbons other than methane, ethane and propane, e.g. a refinery or natural gas by removal of such other hydrocarbons and adjustment if necessary of the methane and/or inert gas content.  2-30 mol. per cent of methane or inert gas may be employed.  The apparatus and process are similar to those of Specification 10532/55. Specification 644,030 also is referred to.
