[Also in Division C1] The active material for a positive electrode consists of solid fluorinated carbon (CFx) n  where n is an integer and x ranges from 0À5 to 1, obtained by fluorination of at least one form of crystalline carbon such as artificial graphite and/or flake graphite. The electrode can be used in a cell having a light metal anode, e.g. Li, Na or Al and a non-aqueous electrolyte, e.g. LiClO 4  in propylene carbonate. A sheet of non- woven polypropylene fabric can be used as separator and the cell is assembled and sealed in an atmosphere of dry argon.  The positive electrode can be made by mixing the fluorinated carbon material with a binder, e.g. polyethylene or polyethylene tetrafluoride, and an electrically conductive agent, e.g. acetylene black, and moulding the mixture about a central metal screen such as a nickel screen, and then sintering. An organic solvent-type binder such as styrol-benzene or a water soluble binder such as carboxymethyl cellulose can also be used and after a paste electrode is formed the solvent can be removed by heating.

Patent GB-596467-A (GB)
Title: The preparation of new polymerisable organic materials and polymers and copolymers thereof
IPC: C08F36/20
Filed: 1945-07-25
Abstract: Polymerizable esters are obtained by reacting in presence of a base a chloroformate of an allyl, or an alpha-methyl and/or beta-methyl or halogen-substituted allyl ester of a hydroxy acid containing one hydroxy, one carboxy and two or three carbon atoms per molecule, with a dihydric alcohol to give a hexa-ester of the formula CH2=CX1.CX2H.O.CO.R1.O.CO.O.Z. O.CO.O.R11.CO.O.CX3H.CX4=CH2, where X1 and X4 may be hydrogen, halogen, or methyl, X2 and X3 are hydrogen or methyl, R1 and R11 are divalent hydrocarbon radicals of two or three carbon atoms, and Z is a divalent organic radical.  The products may be polymerized, e.g. in presence of a polymerization catalyst at raised temperatures.  Chloroformates of the allyl esters specified are prepared from phosgene and the allyl esters themselves.  Allyl esters specified are those derived from allyl, b -methallyl and b -chlorallyl alcohols, or methyl vinyl carbinol and glycollic or hydracrylic acids, and these may be prepared in presence of a catalyst such as p-toluene sulphonic acid.  Dihydric alcohols specified are ethylene, trimethylene, a -propylene and di- and other polyethylene glycols.  Suitable bases are pyridine and quinolines. The esters may be purified by fractional crystallization or distillation, the latter in presence of a dissolved polymerization inhibitor such as hydroquinone disulphonic acid.  A polymerization catalyst specified is benzoyl peroxide which may be used in an amount up to 5 per cent by weight of the ester, which may be polymerized alone or in admixture with methyl methacrylate, vinyl chloride, vinyl acetate, styrene, maleic anhydride, dyes, pigments and fibrous and mineral fillers. The esters may be used to bond sheets of fibrous materials or as coating compositions.  In an example, glycollic acid is heated with allyl alcohol and benzene, the water of reaction is removed by distilling off the water-benzene azeotrope, and the allyl glycollate obtained is reacted with phosgene to give allyl glycollyl chloroformate.  The latter is treated with ethylene glycol and pyridine to give glycol di-(allyl glycollyl) carbonate, which is polymerized by heating with benzoyl peroxide.

Filed: 1927-07-19
Abstract: 274,867. British Thomson-Houston Co., Ltd., (Assignees of Hall, C. I.). July 26, 1926, [Convention date]. Make-and-break switches, mechanical; timing devices.-Lamps 48, 49, 50 are lit in cycles to give " Stop," " Go," and "Change" signals for road-traffic by a controller comprising a motor driving a number of cams, means being provided to regulate the length of the cycle, the ratio of the time intervals of the signals with respeet to one another, and the length of any signal independently of the others. The driving motor comprises a disc 5 and armatures 3, 4, and its speed may be regulated by shading coils adjusted by a knob 8 to vary the length of the cycle. A sleeve 15 carrying cams 20, 21, 22 is frictionally connected to a shaft 16 carrying cams 17, 18, and the sleeve and shaft are rotated by a train of gears 11<a> - - 14. The sleeve 15 and shaft 16 may be turned relatively to each other by a knob 19 secured to the shaft carrying a spring-pressed ball 26 round an apertured disc 23 so that the ratio of the time intervals of the " Stop " and " Go " signals controlled by the cams 17, 21 respectively is varied. A lever 35 carries a bar in the paths of the cams 17, 21 and a bar 56 at the upper end of the lever is thus moved tn allow one or other of spring contacts 32, 33 to fall and engage contacts 41, 42 in the circuits of lamps 48, 49. The cams 18, 22 are adustably secured to the cams 17, 21 and allow the lever 35 to move to such a position that it allows a further spring contact 34 to fall and engage a contact 44 in the circuit of the lamp 50, thereby giving warning of a change in the signal at any desired interval before the change. The cam 20 operates a lever 36 to restore the lever 35 after a complete cycle. A flashing signal only can be given by moving the double-pole switch shown in Fig. 2 to close contacts 51, 53, so that when a spring contact 40 engages a contact 44 in the " Change " signal circuit by the operation of a lever 65 and toothed wheel 64 on the shaft 16, the lamp 50 is caused to flash. The Stop " and " Go " signals may be made to flash by the provision of teeth on the appropriate cams.

Abstract: 1,182,262. Hydraulic shock-absorbers. NICKOLS AUTOMATICS (E.M.I.) Ltd. 2 May, 1967 [2 May, 1966], No. 19249/66. Heading F2S. An hydraulic shock-absorber, to control, e.g. the motion, e.g. of a pneumatic actuator for the turret of a capstan lathe, comprises a doubleacting piston 10 which works in an oil filled cylinder 14 and has a rod 12 for coupling, e.g. to the pneumatic actuator, the two ends of the cylinder 14 being connected by a first path consisting of an external pipe of large bore, e.g. ¢ inch, having one, or as shown, two skip valves 18, 20, and allowing substantial free flow of oil from one end of the cylinder to the other, and a second external path including one, or as shown, two restrictor valves 26, 28, through which a restricted flow of oil may be directed by closing of one of the valves 18, 20, and an air pressurized oil reservoir 24. The valves 18, 20, which are pneumatically operated, electrically controlled, and spring biased to the open position, are arranged in series with the valve which controls the actuator of the turret to assure correct operation. If the electric control is such that air is admitted to the actuators when control current is interrupted the system will fail to safe. With both valves 18, 20 open there is a relatively unrestricted flow of oil between the ends of the cylinder. On forward motion of the rod 12, in the direction of the arrow, the valve 18 is closed so that oil flows through the pipe 36, the restrictor 28, pipe 30, the reservoir 24, pipe 22 and the open valve 20 to the other end of the cylinder 14. The valve 20 closes during movement of the piston in the opposite direction, oil flowing through pipe 34, restrictor 26, pipe 30, the reservoir 24, pipe 22, and the open valve 18, to the front end of the cylinder 24. A buffer valve (42) is included in the pipe to check the return feed of the turret and includes a pneumatically operated piston and cylinder unit (46), (48) which controls a through passage the size of which is controlled by an adjusting nut 52, a microswitch, not shown, being located near the fully retracted position of the turret, Fig. 3, not shown. A further stop valve may be interposed in the pipe 30, Fig. 1.

Abstract: 1,150,212. Sand packing. SPO Inc. 3 May, 1966, No. 19556/66. Heading B3F. Jolting apparatus for use in foundry moulding comprises a table 13 having a stem 15 within which is slidably mounted a stationary support 19 attached to a base 20, the table being resiliently carried on the support 19 by springs 22, 23, an annular jolting member surrounds the stem and in the inoperative position bears against the underside of the table 13, and a member 28 is provided which has inner surfaces which are in sliding contact with surfaces 26, 30 and 32 of the stem, and an inwardly directed flange 37 on the jolt member 35 divides an annular cavity between the stem and member into first and second chambers 40, 41, respectively. In operation gas pressure from a source 44 is supplied through first port means 47 to 51 and 52 to the chamber 40 which causes the jolt member to move downwardly away from abutment with the table 13. This movement causes compression of gas in the second chamber until second port means 54 is opened to exhaust gas from the first chamber 40. When this occurs the pressure in the second chamber 41 rapidly urges the jolt member 35 towards the table 13 to effect the jolting action. The reciprocating movement will continue until the gas pressure from source 44 to the first chamber is stopped. The pressure in the second chamber is maintained by gas supplied from a source 60. In an alternative embodiment the support member forms a piston within the stem of the table so that a squeezing action may be effected by the table when used for jolt squeezing for the production of sand moulds. Also, the apparatus may be inverted and suspended from a structure to facilitate alternative squeezing and jolting operation.
