Filed: 1939-08-15
Abstract: 532,067. Couplings. SIEMENS BROS. & CO., Ltd., and CRUTCH, L. S. Aug. 15, 1939, No. 23558. [Class 38 (i)] [Also in Group XXXIX] In a repeater for connection in a submarine or other cable, the pieces of apparatus A, such as valves, transformers, resistances and so on, are mounted on the sides of metal discs D which are rigidly held together by rods R to permit their mounting in a water-tight casing of circular or elliptical cross-section to form several compartments. A central tube T passing through holes in the discs and having apertures O between each pair of discs carries the wiring W between the compartments. The rods R are insulated from the discs and may be covered with insulation so that they may support the wiring within the compartments. In Fig. 1 the casing C is bolted at each end to a plate DIS which receives the cable ends, and the discs D have spacing pieces SP which bear against the inner wall of the casing. In Fig. 2, the casing PC is of pot form and the rods Rare secured in bosses BT, BS on the plate DIS and on the base of the pot. The discs may be earthed in order to form screens between the compartments. In the arrangement shown for leading in the cable, the end EC of the cable is jointed at J to a stub of concentric cable, of which the inner conductor IC with its covering of insulation PA is passed through a hole in the plate DIS where it is sealed by means of further insulation S, packing material WP and a plug PS. The outer conductor OC is connected by a lug LU to the plate DIS, which may be suitably connected to the casing. The armouring wires AW of the cable are wrapped over a conical sleeve CS and are clamped in a groove in a headplate H by an outer sleeve CC, these members being secured to the plate DIS by long bolts LB. An end cap E covers the whole joint.

Patent GB-649719-A (GB)
Title: Improvements in or relating to the production of interpolymers and of moistureproof sheet wrapping material coated therewith
Inventor: BERRY WILLIAM
IPC: C08J7/052
Filed: 1947-08-29
Abstract: Copolymers suitable for forming moisture-proof coating compositions are prepared by polymerizing a mixture comprising vinylidene chloride, acrylonitrile and one or more of the group consisting of citraconic acid anhydride and mesaconic acid.  The acidic constituent may also be a mixture of citraconic and itaconic anhydrides obtained by distillation of citric acid.  The preferred mixtures contain more than 80 per cent of vinylidene chloride (e.g. 87 per cent), between 0.5 and 10 per cent of the acidic ingredient and the remainder acrylonitrile.  To produce a polymer sufficiently soluble in volatile organic solvents it is generally necessary to use a modifying compound of the formula R.R1C=O, where R and R1 may be hydrogen or a hydrocarbon radical, such as aldehydes and ketones, e.g. methyl isobutyl ketone.  6.5 per cent of modifying compound based on the weight of the polymerizable mixture is preferably used. Polymerization may be effected in bulk, solution or emulsion or by granular processes.  A catalyst, e.g. ammonium persulphate, is preferably employed and may be used with an activator, e.g. sodium metabisulphite.  Dispersing agents such as sodium long chain alkyl aryl sulphonates are used in emulsion polymerization and modifiers such as long chain mercaptans are preferably employed.  An emulsion polymerization is described in which the mixture is maintained at 40 DEG  C. with stirring for 20 hours and the product coagulated with aluminium sulphate.  The polymers may be dissolved in such solvents as methyl ethyl ketone for application to cellulosic base films in the production of moisture-proof, heat-sealable sheet wrapping material.  Specification 622,481 and U.S.A. Specification 2,278,415 are referred to.

Title: Improvements in slitting and rewinding mechanism
IPC: B65H27/00
Filed: 1920-08-18
Abstract: 155,227. Cameron Machine Co., (Assignees of Johnstone, R. M.). Dec. 11, 1919, [Convention date]. Feeding and winding webs.-In order to neutralize the longitudinal irregularities or wrinkles caused by the pull on paper or fabric while being fed through machines, temporary longitudinal minute undulations are formed in the web bv means of a grooved roller or a grooved fixed plate which in the case of cutting machines is preferably placed immediately after the cutters. A slight narrowing of the web results, and hence there is no tendency for the adjacent coils, in rewinding, to interlock. The grooved roller may be, itself, a cutting roller, or the front or back rewinding drum or the top winding drum, or may be in the form of a spring dandy roller. The grooves in the roller or plate may be straight or undulating, as seen developed in Figs. 26, 25, 24, but are always non-helical. Figs. 4 and 5 show a grooved roller 18 which acts also as the roller against which the score cutters 23 cut, smooth spaces 33 being left for this purpose. Fig. 7 shows a similar roller which acts as a shear cutter. Fig. 12 shows the drum 18 as a top pressure roller. Fig. 14 shows a grooved plate 18<b> which may be used instead of the roller. In each Figure the re-winding shaft is shown at 22, and the cutter at 23.

Filed: 1926-10-01
Abstract: 282,899. English Electric Co., Ltd., and Law, A. H. Oct. 1, 1926. Friction wheels.- In friction gearing of the kind in which a floating ring or rings is employed to maintain in frictional contact a group of rollers lying therewithin, for example as described in Specification 234,669, each ring is composed of two or more concentric parts 11, 12, 13, each ring being shrunk upon the ring or rings within it. The inner surface of the ring 11 thus has an initial circumferential compressive stress. Preferably the rings increase in thickness with their diameters. Each ring is case hardened and ground true, or the inner ring may be of material having a hard structure throughout, the composite ring being reground if necessary. As shown, the floating ring is built up of six groups of rings bearing upon a driving- roller 1 and an idler 4, both of which engage a driven roller comprising six hard steel rings 7 bolted together and keyed upon a shaft 9. The floating ring may be positioned by stationary thrust pads of the kind described in Specification 259,387 bearing against its ends.

Filed: 1976-08-11
Abstract: 1523009 Latch mechanism E WHITTAKER 11 Aug 1976 [11 June 1976] 24321/76 Heading E2A  A door latch comprises a rotary bifurcated bolt C biased to the unlatching position by spring E and cam surfaces S, T which bias the keeper towards the bolt into two fastening positions. The keeper comprises a link I able to pivot within narrow limits and bearing a striker pin H. The pivoting of the keeper is controlled by cam follower K 1  hinged at M to slide L and biased towards link I by torsion spring N. Slide L is biased outwards by spring O. Initial engagement of cam follower K, with cam S and pin H with leading edge C, of bolt C forces slide L against spring O until it retracts enough for pin H to pass down C 1  and around the nose into gap C 2 , when cam follower K 1  rises up cam S and forces pin H into the fork of bolt C to give a "safety" latching engagement (Fig. 4). Further inward movement of the keeper rotates the bolt and causes its leading edge to depress cam follower K 1  with cam S lodged in recess K 2 . The bolt C passes through a "dead-centre" position and then draws pin A inward with cam follower K 1  riding, as before, up cam T, contacting the leading edge C, of the bolt and wedging the fastening (Fig. 5). To undo the fastening finger P 1  is rotated to withdraw the slide L and hence cam follower K 1 , allowing the keeper to be withdrawn. A locking mechanism is provided. wherein detent L may be moved by cam X to engage pin P 1  and prevent its rotation.
