Title: Polymerization of alpha-halogen substituted acrylic compounds
IPC: C08F20/62
Filed: 1946-05-23
Abstract: Colourless transparent polymers are produced by polymerization of monomeric a -halogen acrylic acid compounds in the presence of 0.1-15 per cent of the monomer of a compound soluble in both the monomer and corresponding polymer and which reacts with any oxalyl halide compounds present or which may be formed during or after polymerization.  Specified compounds are lower molar weight monohydric alcohols, e.g. methyl, ethyl, n-propyl, isopropyl, n-, sec.- and tert.-butyl, amyl, cyclohexyl, allyl, methallyl, crotyl, benzyl and cinnamyl alcohols.  Listed a -halogen acrylic acid compounds include methyl, ethyl, propyl, butyl, phenyl, benzyl, cyclohexyl, allyl and methallyl esters of a -chloro- and a -bromo-acrylic acids, a -chloroacrylamide, N-methyl a -chloroacrylamide and the corresponding a -bromo compounds and a -chloroacrylonitrile.  The process may be carried out in mass, by solvent, granular or emulsion polymerization methods and may be promoted by use of light or other catalysts, e.g. benzoyl, succinyl peroxides, peracetic acid.  Generally, polymerization is effected by heating, e.g. at 20-120 DEG  C., preferably between 35 DEG  and 65 DEG  C., and the polymer subsequently hardened by heating between 100 DEG  and 120 DEG  C. for from 8-24 hours.  The products may be moulded, e.g. to form optical media, which are scratch-resistant, transparent and non-brittle and which may be shaped by grinding and polishing.  Specifications 518,970, 527,494, 618,965, [Group IV (b)], 636,318, 636,320, 636,321, 636,322, and U.S.A.  Specification 2,247,790 are referred to.

Title: Process for the production of filaments and foils from poly-bis-1,2,4-triazoles
IPC: C08G73/08
Filed: 1968-04-02
Abstract: 1,215,067. Poly - bis - 1,2,4 - triazole filaments and films. GLANZSTOFF AG. 2 April, 1968 [8 April, 1967], No. 15691/68. Heading B5B. [Also in Division C3] Poly-bis-1,2,4-triazole films or filaments are produced by dissolving a polyacyl oxamidrazone of the formula in which R represents an aromatic ring system or a -CH=CH- group, in aqueous alkali metal hydroxide, spinning or pouring this solution into an acid precipitation bath; washing and then heating the resultant foils or filaments in an inert atmosphere to a temperature of 230‹ to 350‹ C. to produce the triazole rings. The heat treatment may be started at one temperature and the temperature gradually increased. The filaments or films can be stretched in the spinning bath, or before, during or after the washing. Polyterephthaloyl or polyisophthaloyl oxamidrazone can be used as starting material. Dilute inorganic acids, solutions of salts of strong acids with weak bases e.g. NH 4 Cl, or acid salt solutions are suitable precipitation bath liquids.
Patent GB-1501433-A (GB)
Title: Devices for locking a spool on a hub
IPC: G11B15/66
Filed: 1975-04-16
Abstract: 1501433 Securing reels on hubs COMPAGNIE INTERNATIONALE POUR L'INFORMATIQUE 16 April 1975 [17 April 1974] 15737/75 Heading F2U  A reel 1 is locked and unlocked respectively on a hub 2 by successive repeated to-and-fro movements of a member 8. The member 8 may be moved rearwardly towards the portion 35 of the hub either manually or electromagnetically against the action of a return spring 6, the member being secured both to a sleeve 5 which slides over the hub drive-shaft 4 and a rod 9 which slides through the shaft. The sleeve 5 has a groove 7 for carrying one end of three springs 19, three pivots 14 for levers 13 and a pair of pins 23, 24 for co-operating with an annular toothed cam 25 which is free to turn in a groove 26 of the hub. Successive axial movements of the sleeve 5 with its pins 23, 24 causes the cam to step round such that alternate movements permit the pin 24 to enter a groove 28 and increase the length of the return movement to cause a locking action. In the unlocked position shown in Fig. 2 and Fig. 7 (A) the reel 1 is slipped on the hub. During the first rearward movement of the member 8, when the pin 23 steps round the cam, Fig. 7 (B), the levers 17 flip round on their pivots 18 as the springs 19 pass their over-centre positions so that arms 20 press the reel axially against a flange 3 of the hub. Upon the first return movement of the member 8 under the action of the spring 6, the pin 24 enters one of the grooves 28, Fig. 7 (C) to cause the shoes 12 to project radially further in their recesses by their levers 13 and lock radially against the reel 1 through the interposition of a friction tape 30; during this action the levers 17 remain in axially-pressing engagement. The reel now is fully looked. To unlock the reel a second rearward movement of the member 8 is made; this causes the cam to step round by the action of the pin 23 so that upon the second return movement when the pin 24 again enters a groove intermediate the grooves 28, Fig. 7 (A) the shoes 12 remain retracted, Fig. 2, and the reel 1 can be slipped off the hub against the spring pressures of the levers 17 causing the levers to pivot back to the position shown in Fig. 2.

Title: Improvements in or relating to apparatus for indicating whether or not a potential difference exists between two conductors
IPC: G01R1/067
Filed: 1938-05-27
Abstract: 515,261. Electric tests. REYROLLE & CO., Ltd., A., HARLE, J. A., LEYBURN, H., and WATERS, M. May 27, 1938, No. 15847. [Class 37] A combination of an instrument for indicating the existence of a potential difference between two conductors and testing means for simultaneously testing the instrument and its connections. The prod 3 is connected to a tube 2 which forms one plate of a condenser, the other plate being tube 4 and the dielectric of the condenser consisting of synthetic resin impregnated paper formed in layers. A metal cup 6 provides connection between the tube 4 and one side of gas discharge tube 8. The other side of tube 8 is connected to earth through clip 13, wires 14, insulated lead 15 and the secondary of transformer 16. The tube 8 serves as an indicator and is viewed through the tube 11. A screen 5 is embedded in the dielectric and is connected to the wires 14. The earthed metal cap 9 is fitted with an insulating handle 10. When testing a conductor the prod 3 is placed thereon and the tube 8 is viewed. If this tube is not glowing it is not taken as an assurance that the conductor is earthed until the apparatus has been tested in situ. To do this the switch 17 is closed between the oscillator 18 and transformer 16 to inject a high frequency current into the indicator circuit. If the tube 8 still fails to glow it will show that the previous indication is unreliable as the apparatus or one of its connections to conductor or earth is faulty.

The train comprises (1) a crane truck, a platform truck and a second crane truck for taking up the old track, (2) a motor truck with dynamo supplying power to the cars, (3) an excavator wagon, (4) a screening wagon followed by two or more hopper wagons for the useless ballast, and (5) a second crane and platform set for supplying the new track. Ballast wagons may be added for making up the track with new ballast. Each crane 17, Fig. 2, is carried on a frame 14 with hinge 15 and screw adjustment 16 for levelling and has a roller block 19 running between irons 2J as the jibs are swung out over the old roadbed. The excavator, Fig. 3, has an endless chain of buckets 23 moving around a triangle with sides 24 - - 26 adjusted by racks or screws. The pivot 28 is hollow to convey the material on to a conveyer 30 leading to the screener 32, Fig. 6. The screened ballast passes back 'by lateral conveyers 37 to a transverse conveyer 38, Fig. 5, which throws it on to the road-bed. The spent ballast is led by a central conveyer 34 to a scraperconveyer 35, Fig. 7, having a channel with hinged base discharging into a hopper-car 7, the base being closed when the car is full and the spent ballast taken to the scraper-conveyer of the next hopper-car. The excavator and screener may be mounted on one truck. When the excavator and cranes are aligned lengthwise, the whole train is within maximum loading-gauge. In operation, the cleaned ballast is levelled manually, but the finished track can be tamped mechanically from a compressor truck at the end of the train.
