Abstract: A rigid sheet comprises a polymeric constituent formed from monomers in which vinyl chloride predominates and reinforcing fibres, the polymeric constituent being rigid at room temperature when not reinforced, and the fibres being uniformly dispersed throughout and all lying in or substantially in the plane of the sheet. In one embodiment the polymeric constituent comprises a dispersion or emulsion of polyvinyl chloride in water together with a solution of a vinyl chloride copolymer in an organic solvent e.g. a vinyl chloride/vinylidene chloride copolymer dissolved in toluene or a vinyl chloride/vinyl acetate copolymer dissolved in methyl ethyl Ketone and, optionally, a hydrocarbon fraction.  Alternatively, the polymeric constituent comprises a mixture of the said copolymers, one being dispersed in a solution of the other e.g. the vinyl acetate copolymer is dispersed in a toluene solution of the vinylidene chloride copolymer.  Asbestos and/or glass or organic fibres are added.  In the first example toluene solutions of a vinyl chloride/vinylidene chloride copolymer and of a styrene/diester of maleic acid and a C8 alcohol copolymer are mixed with additional toluene, powdered polyvinyl chloride, an aqueous polyvinyl chloride latex, stabilizers, talc, asbestos and pigment. This mixture is used to form the base layer of a laminated sheet and a similar mixture, without the styrene copolymer and containing a greater proportion of polyvinyl chloride, is used to form the body layer.  The aqueous phase of both mixtures may contain a minor amount of another latex e.g. a butadiene/acrylonitrile copolymer latex.  In the second example the body layer comprises a toluene solution of a vinyl chloride/vinylidene chloride copolymer, a vinyl chloride/vinyl acetate copolymer, asbestos stabilizers, talc and water.

Abstract: 1,219,569. Shaft seals. DUNLOP CO. Ltd. 29 May, 1968 [30 May, 1967], No. 24776/67. Heading F2B. A shaft sealing ring 1 comprises an elastomeric sealing lip 2 formed with a series of studs 8 which entered around the periphery of the ring adjacent the lip sealing area 4, 9 and, in use, create a pumping action tending to return fluid leaking past the lip sealing area. In the embodiment shown, the lip 2 is urged against a rotatable shaft (not shown) by a garter spring 7 and prevents leakage of oil from side 5 to side 6 of the ring. Figs. 1 and 2 show the ring in its initial unworn condition and Figs. 4 and 5 show the ring when worn. In the unworn state the lip has a sealing edge 4 and the studs are inoperative. After a period of use, the edge 4 and the studs 8 are worn down to provide a cylindrical sealing area 9 as in Figs. 4 and 5, each stud forming a dovetail extension of the area 9 having curved surfaces 10 and 11 which act, according to the direction of shaft rotation, to return any oil droplets leaking past the area 9, to the side 5 of the ring. In a modification, Figs. 7-12 (not shown), the studs (22) are spaced apart from one another. In another modification, Figs. 16-18 (not shown), the end faces (44) of the studs (42) are conical. If desired the region of the ring adjacent the studs may be formed, for example by trimming, to render the studs operative to oppose leakage in the initial unworn state of the ring.

Abstract: 781,045. Beta-ray density gauges. WILLIAMS, H., and MOLINS MACHINE CO., Ltd. Sept. 7, 1954 [Sept. 8, 1953], No. 24777/53. Class 40 (3). In a beta-ray density gauge comprising a betaray source, and an ionization chamber which may be pivoted into position to receive radiation which has traversed the object under test a pair of slidable shutters are arranged to come together and cut off the beta-radiation, the arrangement being that the first shutter is coupled to the chamber and the second shutter to the first so that second moves towards the first when the first starts to move. As shown, the beta-ray source 1 passes radiation through a cigarette rod 2 passing between guides 3, 4 to an inization chamber 12. Chamber 12 is mounted in a support 13 which may pivot at 14 to rest on a buffer 19. During the pivotal movement levers 20, 21, 22 and 25 raise the lower screen member 27 (Fig. 2) which then starts to cut off radiation from the source. Member 27 carries on a pivot 35, levers 36, 37 joined by links 42, 43 to the upper shielding member 32. The links have surfaces 38 which co-operate with fixed cams 39, 40. Thus as the lower shield rises levers 36, 36 are rotated and upper shield member 32 rapidly approaches the lower one. When the shields are in contact the entire assembly moves upwardly until a window 44 of transparent beta-ray-proof material allows inspection of the beta source. As the ionization chamber is pivoted back to its operative position cam follower 38 contacts cam 41 separating the upper and lower shield members again. Specification 781,043 is referred to.

Title: Method of embossing and colouring polyvinyl materials
Inventor: HOGG WILFRED HENRY
IPC: D06Q1/08
Filed: 1950-10-12
Abstract: A leaf of a vinyl polymer which softens at a low temperature and which contains colouring matter dispersed therein, is superposed on a polyvinyl material and impressed with a hot die to fuse the leaf and material together to form coloured embossments. From 50 to 200 parts of the colouring material, e.g. metal powders such as bronze or aluminium and other, particularly inorganic pigments, are added to 100 parts of the vinyl polymer.  Suitable vinyl polymers soften at about 60-130 DEG C., e.g. copolymers of vinylchloride with one or more other mono-olefinic compounds containing a CH2=C< group, and particularly a copolymer of vinyl chloride and vinyl acetate containing 5-15 per cent. by weight vinyl acetate, a ternary copolymer of vinyl chloride, vinylidene chloride, and vinyl acetate, or vinyl chloride/vinylidene chloride copolymers containing 10-30 per cent. by weight vinylidene chloride.  The leaf is formed by dispersing the colouring matter in a solution of the polymer in a volatile solvent and evaporating the solvent.  The solvent may be a mixture of toluene and acetone, methyl ethyl ketone, methyl isobutyl ketone, or a mixture of either of the two latter with toluene or xylene.  A small proportion of a heat stabilizer for the polymer, e.g. lead stearate or cadmium stearate, is desirably added.  The dispersion is spread on a glass or metal plate or conveyer belt to a thickness of 0.0025-0.015 inch by a doctor blade and dried by a gentle air current.  Leaf of 0.004 inch upwards may be formed by calendering the copolymer with the colour dispersed therein, and this leaf may be thinned by stretching.  The die is heated to 110-150 DEG C. and, to prevent sticking, may be left to cool while in contact with the material, or coated with an aqueous solution, e.g. of glue size, polyvinyl alcohol, sodium alginate, methyl cellulose, or albumen, which dries but does not become tacky on heating.  An example contains Geon 400 x 65 (a ternary copolymer of vinyl chloride, vinylidene chloride and vinyl acetate) 100 parts, toluene 650 parts, acetone 350 parts, bronze powder 125 parts. and cadmium stearate 1 part.

Title: 3 digit pbx connector
IPC: H04Q3/00
Filed: 1950-10-13
Abstract: 683,339. Automatic exchange systems. AUTOMATIC ELECTRIC LABORATORIES, Inc. Oct. 13, 1950 [Nov. 26, 1949], No. 25048/50. Class 40 (iv). A final selector of the Strowger type, especially for making connection to an idle line in a P.B.X. group, responds to three digits, the first digit selecting the level, the second digit rotating the wipers to the first contact of the group and the third digit indicating the number of lines in the group to be tested. A calling subscriber, over a preceding switch train, seizes the final selector over line conductors 93, 94 by operating line relay 10 to energize release relay 20 and busy control conductor 92, which has meanwhile energized transfer relay 30. Line relay 10 responds to the first digit and pulses the vertical magnet 1 to lift the wipers 6-9 to the selected level, V.O.N. contacts 2, 3 reversing at the first step. At the end of the digit, transfer relay 30 falls back slowly to prepare the circuit for pulsing the rotary magnet 4, which responds to the second digit through the winding of series relay 40. Relay 40 operates to by-pass armature 78 and energizes ring cut-off relay 70, which locks up and grounds supervisory lead 91. Relay 40 restores at the end of the second digit. The first pulse of the third digit is absorbed in operating busy and test relay 50, which locks up over contacts 54. After the first pulse, line relay 10 re-energizes and operates relay 30, which locks up, releases relay 70 and opens the locking-circuit of relay 50. If wipers 7, 8 find battery on contact 201, indicating an idle line, busy relay 50 restores to operate switching relay 60 and release transfer relay 30. Switching relay 60 locks up, starts the ringing machine, returns ringing tone to the calling party and breaks the circuit to the rotary magnet 4 so that the remaining impulses of the third digit are ineffective. Relay 60 completes the circuit for ringing the called party through the upper winding of ring cut-off relay 70. When the called party answers, relay 70 operates and locks up to remove ring-back tone and energize back-bridge relay 80 over the called loop. Relay 80 reverses the polarity over the calling loop and completes the talking connections. If, on the other hand, wipers 7, 8 find ground on contact 201, indicating a busy line, busy relay 50 locks to this ground so that relay 60 remains inert. Line impulses then step the wipers as before until an idle line is found or until the digit is ended. In the latter case, relays 50 and 30 remain operated and 70 remains released to return busy tone to the calling party. Calls to individual lines are made by using one as the third digit.
