Filed: 1961-01-17
Abstract: 989,291. Piston packings. DUNLOP RUBBER CO. Ltd. Dec. 22, 1961 [Jan. 17, 1961], No. 1820/61. Heading F2T. A thimble shaped rolling lobe diaphragm, Fig. 8, is made of an elastomer having at least two layers of reinforcing textile cords which extend longitudinally of the walls of the thimble, the cords in one layer intersecting with the cords in the other layer. The diaphragm may be used in an hydraulic mechanism in which it is clamped at its open end in a cylinder whilst a piston extending inside it reciprocates with its top portion whereupon its walls are flexed between the piston and the cylinder to prevent fluid from escaping past the piston. In making the diaphragm, a sheet of cords, obtained by slitting open a tube formed of helically wound silk, rayon or polyethylene terephthalate cords coated with a vulcanizable rubber composition, is wrapped around coaxially aligned formers with the cords inclined relative to their longitudinal axes. The sheet, Fig. 5, is pinched as at 5 around a pin 15 extending from the former 13 into a groove in the former 12. The portion of the sheet on the former 13 is then rolled on to that on the former 12 to form a thimble which is then transferred to a tapered former 16, Fig. 7.

Patent GB-584828-A (GB)
Title: Hydrolysed interpolymers of acrylonitrile and vinyl esters
IPC: C08F8/12
Filed: 1945-01-26
Abstract: Interpolymers of acrylonitrile and vinyl esters of organic carboxylic acids are hydrolysed to yield products which are resistant to water and to high temperatures and are substantially unaffected by outdoor exposure.  The molar ratio of acrylonitrile to vinyl organic ester should be within the range of from 1/10 to 10/1 so that the resulting hydrolysed interpolymer is soluble in solvents such as acetone and dimethyl formamide, and may thus be dry spun or converted into shaped articles such as filaments, fibres and films.  For oriented films and fibres it is preferred to use interpolymers in which the molar ratio is between 1/3 and 3/1 .  The term "hydrolysis" here includes alcoholysis as well as hydrolysis with the use of water in the presence of a base or an acid, and part or all of the ester groups may be replaced by hydroxyl groups.  One of the methods by which the process may be carried out consists in controlled hydrolysis by means of an alcoholic or aqueous alkaline solution of the interpolymer and separating off the hydrolysed product.  Another method consists in passing the already spun fibres of the interpolymer through a suitable hydrolytic bath.  Or an alkali may be added to an aqueous dispersion of the interpolymer, and the resulting product precipitated as by the addition of a salt.  The articles prepared by this invention, such as fibres or filaments, are stretched to at least twice their original length.  After-treatments upon the hydrolysed interpolymer may be carried out to increase the softening temperature of the material.  For this purpose, cross-linking agents such as the methylolureas, formaldehyde, polybasic acids or diisocyanates may be employed.  The vinyl organic esters specified are vinyl acetate, propionate, butyrate, benzoate, isobutyrate, pimelate and vinyl 2-ethyl hexanoate.

Abstract: 328,229. Miller, J. G., and Bullers, Ltd. Jan. 21, 1929. Holders for cables and conductors.-A self-releasing suspension clamp for electric cables comprises a cradle - member pivoted to a suspension member, the relative pivotal movement between the members moving a clamp towards, or away from, the cradle member, so that the clamp will release the cable if the line should break. In the embodiment, a cast iron triangular plate 1 is formed with a cradle 2 for carrying the cable. A gap 3 is formed in the cradle channel and an aperture is provided in the plate 1. A boss 6 in the plate 1 is adapted to carry a bolt 7 on which is pivoted a link 8. A link 9, forked at both ends, is pivoted to the link 8 and on a pin 10, and to a clamp 12 by a pin 11. The clamp 12 is channelled to fit over the cable, and is formed with an upstanding lug 14 pivoted to the pin 11. Bolts 15 connect the clamp 12 to an extension 5 of the plate 1. A suspension member 16 is formed with a forked end 17 pivoted to the plate 1, one limb of the forked end being slotted to pass over the pin 10 and to provide lost motion. In operation, a reduction in tension on one side of the clamp due to breakage of the line causes the cradle to move relatively to the suspension member, thus releasing the cable from the clamp. In a modified construction, shown in Figs. 5 and 7, a cradle 22 is formed with curved arms 23 pivoted by links 27, 28 to a clamp 25. Bolts 31 pass through the clamp 25 and the cradle 22. The forked end 33 of a suspension member embraces the cradle 22 and is pivoted to the cradle by bolts 34. Lost motion is provided between the suspension member and the cradle by a peg 35 which engages a slot 36 in a cross-link which connects the intermediate pivot pins of the two sets of links.
