Title: Improvements in processes for applying surface coverings of plastic composition
IPC: B05D3/02
Filed: 1951-11-27
Abstract: In a thermal process for applying to wires, filaments and other surfaces coverings of plastic composition based on cellulose esters and furfural, the exact baking temperature of the mixture at which reaction of the furfural with the cellulose ester takes place is indicated by including in the basic mixture malachite green or other amino or alkylamino dye of the triphenylmethane group or nigrosine or other dye of the azine group, e.g. safranines and derivatives thereof, mauvines and indulines.  These dyes may be used mixed with other dyes which remain stable at the temperature in question, e.g. dyes of the azo group.  An indicator of malachite green and Azosal (Trade Name) in a mixture based on cellulose ester and furfural gives the mixture a black colour turning red when raised to 260 DEG  C.

Title: Improvements in or relating to switching arrangements comprising mechanical energy storage means
IPC: H01H3/30
Filed: 1962-07-19
Abstract: 958,743. Electrically tripped switches. SIEMENS-SCHUCKERTWERKE A.G. July 19, 1962 [July 24, 1961], No. 27806/62. Heading H2B. A circuit-breaker or rectifier shorting switch having energy storage means releasable to effect operation has a piston which is pneumatically or hydraulically operable to restore the contacts and recharge the energy storage means, the piston also constituting an armature of an electromagnet so that the restoration of the contacts and recharging of the storage means can be performed electromagnetically. As shown, a three-phase shorting-switch has fixed contacts 1 and a bridging disc 2 provided with two separated contact buttons 2a for each fixed contact. The storage springs 7 act on the disc 2 to urge it into engagement with the fixed contacts 1 and it is retained by a shaft 3 held in the position shown by these aligned cylinders 13. When a trip coil 8 is energized a plunger 11 moves the middle cylinder 13 to the left against the biased pin 4a and the shaft 3 and contact disc 2 are moved downward by springs 7 assisted by disc springs 14. After contact engagement the shaft 3 engages a resilient steel seating 15 on the piston 12 so that its inertia is absorbed by the piston and a spring 16 below the piston. The piston 12 may be moved upward to open the contacts 1, 2 by compressed air supplied through a pipe 20 or by energization of a coil 19 to attract the magnetic piston 12 to the magnetic casing part 17. As the shaft 3 is moved upward the middle cylinder 13 is realigned with the other cylinders by the biased pin 4a to hold the contacts open.

Title: Carbon-filled sheet and method for its manufacture
IPC: D21H17/67
Filed: 1962-07-19
Abstract: A carbon-filled sheet which may be used as a filter or by further treatment as an electrically conductive sheet is produced by the steps of preparing an aqueous slurry of fibres and carbon particles which is fed to a paper machine headbox while simultaneously feeding thereto a colloidal solution of a cationic agent the entire slurry then being deposited immediately on the screen of a paper making machine.  The carbon content of the sheet may lie within the range of 15% to 75%.  As shown in Fig. 1 a dispersing agent may be fed into the slurry of fibres and carbon in the beater to ensure homogeneity of the slurry and an acid agent e.g. alum or hydrochloric acid is added to the headbox to maintain the pH of the mixture between 3 and 6 and preferably between 4 and 5.  The carbon may comprise activated carbon particles up to 150 mesh size but preferably less than 325 mesh, or for the conductor sheet, graphite particles up to 100 mesh in size and preferably less than 200 mesh.  The colloidal cationic agent is preferably an aminemodified starch and is added to the slurry in amounts ranging from 0.2% to 10% of the solids content, a substantial portion of the cationic agent being retained in the final product.  The fibres used are preferably cellulosic but may be combined with or even replaced by organic or inorganic synthetic fibres such as regenerated cellulose acetate rayon, polyamide, vinyl acetate and vinyl chloride copolymer, polyester, glass, quartz and ceramic fibres, the last named including a mixture of fused alumina and silicate fibres.  Where the sheet is to be used as an electrically conductive paper it is further treated by impregnation with a dispersion of graphite particles in a suitable resin, excess impregnating material being removed, the sheet dried and then supercalendered.  The resin used is preferably of the type having a low dielectric constant and which provides a waterproof coating resistant to acids and alkalis. Chlorinated natural rubbers and chlorinated resins are particularly suitable.  Specification 961,637 is referred to.

Title: Improvements in or relating to polymer manufacture
IPC: C08G81/02
Filed: 1963-07-16
Abstract: In a process for polymerizing a conjugated diene using an organo-lithium catalyst, 0.02 to 1.0 parts by weight of a multivinyl aromatic compound per 100 parts of the diene are added to the polymerization mixture to reduce the cold flow tendency of the polymer without producing gel.  Specified dienes are butadiene, isoprene, piperylene, 2,4-dimethyl-1,3-butadiene, 1,3 - octadiene and 4,5 - diethyl - 1,3 - octadiene. Specified multivinyl aromatic compounds include benzene, naphthalene and biphenyl derivatives. Divinyl benzene is exemplified.  The catalyst has the general formula RLix, where R is an aliphatic, cycloaliphatic or aromatic hydrocarbon radical containing from 1 to 20 carbon atoms and x is an integer of 1 to 4.  n-butyl lithium is exemplified.  Random or block copolymers may be formed by copolymerizing the dienes with minor amounts of mono-vinylidene-containing monomers.  In one example, butadiene and styrene are copolymerized in the presence of tetrahydrofuran to prevent block copolymer formation.  The usual hydrocarbon diluents such as cyclohexane are used.  The polymerization is terminated with a solution of 2,21-methylenebis - (4 - methyl - 6 - tert - butyl - phenol) in a mixture of toluene and isopropyl alcohol.  The polymer may be vulcanized using conventional techniques.

Abstract: 445,199. Nail - cutting machines. BRITISH UNITED SHOE MACHINERY CO., Ltd., COOPER, B. P., HENSHAW, J. N., Belgrave Road, Leicester. Oct. 3, 1934, No. 28267. [Class 83 (iv)] In a machine for forming tacks or like fastenings from strip material fed to stripsevering means through a guide for the material, a driving device is incorporated which imparts to the guide rotary and transverse movements. The machine is similar in construction to that described in Specification 116,097, [Class 83 (iv)], but differs in the drive for lifting and rotating the guide or stripcarrying nozzle. The shaft 19 is driven at constant speed in timed relation with mechanism for actuating the shear blades for severing a tapered blank from the end of the strip 1. A universal joint connects the driving shaft 19 with a shaft 23 which is carried in a vertically adjustable bearing. On the end of the shaft 23 a flanged disc 29 and a pinion 27 are keyed, both offset from the axis of the shaft by approximately the same amount, Fig. 2; the pinion has a plain portion 31 equal to its pitch diameter which is arranged to engage with a plain portion 45 on a pinion of equal size which is carried eccentrically by a short shaft 35. The latter is carried by a vertically slidable member 49 connected. through yoke-and-link mechanism to the nozzle carrier. A sprocket wheel 37 on the end of the shaft 37 drives, through a chain 39, a wheel of twice its diameter to rotate the blank-carrying nozzle. The pinion 27 is in its lowest position as shown, Figs. 1 and 2, during which the strip is being sheared and the speed of rotation of the nozzle is substantially nil, the speed increases gradually as the centre of the pinion moves through the circular path Y, Fig. 2, and its point of tooth engagement with the wheel 33 is moved farther from the centre of rotation of the shaft 23, reaching a maximum when the nozzle is at its position of maximum lift ; the speed of rotation then decreases until it is again substantially nil when the strip has completed 180‹ of rotation and rests again on the shearing die for the next cutting operation.
