Filed: 1949-03-15
Abstract: 658,341. Magnetic tests and measurements. OFFICE NATIONAL D'ETUDES ET DE RECHERCHES AERONAUTIQUES. March 15, 1949, No. 7012. Convention date, Aug. 5, 1948. [Class 37] Apparatus for measuring magnetic field strength comprises a magnetic member the permeability of which is affected by the field, projecting into a short length of wave-guide fed with U.H.F. A.C. and tuned by a plunger. The reading of a meter measuring the standing voltage at a suitable point is thus a measure of the field strength. To compensate for variations with supply voltage, the voltages at corresponding points in guides which are identical except that one has a conducting bar M' (Fig. 2) in place of the magnetic bar M are compared. In another embodiment (Fig. 3) a wave-guide CD tuned by plungers (not shown) and containing bars or rows of bars at the ends the bars at one end only being magnetic, has a detector S connected to the large side of guide CD. This arrangement avoids the errors in the Fig. 2 arrangement due to imperfections in the mounting of the probes and pistons.

Title: Improvements in transfer sheet arrangements for use with continuous copy sheets in typewriters and the like
IPC: B41J17/00
Filed: 1937-03-10
Abstract: 490,401. Carbon paper assemblages. DOUGLAS, W. March 10, 1937, No. 7039. [Class 16] In a set of carbon trans fer sheets the sheets bave headings embraced be tween a pair of paper or like strips which project at both ends laterally beyond the sheets, and the strips are secured together only at one or both ends and to the headings of the sheets at two separated points and extend beyond the points of attachment tc within the width of the transfer sheets. In one form several superposed transfer sheets each provided with laterally projecting reinforced headings are embraced by two stiffer strips of manilla paper which extend across the headings and are secured together at both ends, and to the transfer sheets at both lateral borders, by eyelets. In another form, the transfer sheets are secured to the embracing strips at two separate points at one lateral border only, and the top edges of the headings of the sheets are sloped to facilitate interleaving the record sheets. In a modification of the latter form, some transfer sheets are secured together and to the embracing strips at one lateral border, and the remainder of the transfer sheets are similarly secured at the opposite lateral border. In the arrangement shown, the embracing strip b, which when the set is being used is situated below the set, is divided at m and each portion thereof provided with a tongue e. The strips b are secured together and to the transfer sheet headings by eyelets e. With fanfold record sheets or webs, one tongue e is inserted between the first and second record sheet whilst the other tongue e is inserted between the second and third record sheets. In a further form, one of the embracing strips extends as a backing strip the full length of the transfer sheets, and the other is also of extended form, but after extending partly of the length of the transfer sheets is then reversely folded to extend above the top edges of the transfer sheets to facilitate the passage of the set between the platen and pressure rolls of a typewriter. In a modification of the latter form, the two embracing strips are integral, and the fold which occurs at the top edges of the transfer sheet headings is slotted to permit the passage of webs of record sheets between the strips. Further, the other fold in the strip which extends upwardly of the set is also slotted or cut away to reduce the thickness of the set. The heading of the transfer sheet may be a folded paper strip secured together at the free ends to form a guide sleeve for the web of a set of interfold copy sheets, the transfer sheet being adhesively attached to one surface of the sleeve.

Patent GB-712042-A (GB)
Title: Improvements in or relating to method of forming fibres, ribbons, films, and similararticles
IPC: D01F6/18
Filed: 1951-03-28
Abstract: Fibres, films, ribbons and similar articles are produced by extruding an ethylene carbonate spinning solution of an acrylonitrile polymer or copolymer into a coagulating bath comprising dipropylene glycol. Either a polyacrylonitrile or a copolymer of acrylonitrile containing at least 80 per cent. of acrylonitrile may be used.  Examples given are copolymers with b -morpholino-ethylvinyl ether, vinyl esters, ethers and ketones, acrylic acid and other unsaturated acids, their esters, amides or nitriles, styrene and substituted styrenes and N-vinyl compounds. The spinning solutions have a solid content of between 15 per cent. and 30 per cent. of polymer.  The coagulating bath containing dipropylene glycol should contain less than 30 per cent. by weight of ethylene carbonate and recovered dipropylene glycol may be added during the process to effect this.  It is advantageous to use a bath which, exclusive of ethylene carbonate, consists of pure dipropylene glycol, but the commercial grade can be used containing impurities such as mono-, and diethylene glycols or mono-, and tripropylene glycols, provided the impurities do not exceed 25 per cent. by weight, exclusive of ethylene carbonate.  The fibres, which are withdrawn from the spin bath at high speeds, are easily washed with water and can be stretched and heat treated.  The use of dipropylene glycol enables bath temperatures of 80 DEG C.-150 DEG C. to be used with spinning speeds of 30-200 metres per minute, fibres of good quality being obtained.  Further, losses due to decomposition and transesterification of ethylene carbonate, which occur with other glycols, are almost negligible with dipropylene glycol and recovery of both ethylene carbonate and dipropylene glycol is readily effected, enabling the process to be worked continuously for long periods.  Specification 676,889 is referred to.

Title: A new dinitrile disulphide compound
IPC: C08L21/00
Filed: 1961-02-28
Abstract: Synthetic rubbers are vulcanized by 2, 2,21-dithiobis-isobutyronitrile in amount of 0,5 to 5 parts by weight per 100 parts of rubber.  Suitable rubbers are the highly unsaturated synthetic rubbers such as styrene-butadiene and acrylonitrile-butadiene copolymers.  The compound may be used alone or in conjunction with other vulcanizing agents when it acts as an accelerator.  Examples of other vulcanizing agents are maleimide, N-phenylmaleimide, N-isopropylmaleimide, N-ethylmaleimide, N-3-chlorophenylmaleimide, N-1-naphthylmaleimide, N,N1-ethylene-bis-maleimide, N,N1-m-phenylene-bis-maleimide, N,N1-p-phenylene-bis-maleimide, 2,6-bis-(maleimido methyl)-4-t-butyl phenol and N,N1-(2,4-tolylene)-dimaleimide.  Examples describe the vulcanization of rubber compositions containing the 2,21-dithiobisisobutyronitrile and carbon black.ALSO:The invention comprises 2,21-dithio-bis-isobutyronitrile and its preparation by the reaction of elemental sulphur with 2,21-azo-bis-isobutyronitrile in an inert solvent.  The reaction yields a mixture of tetramethylsuccino-nitrile and the desired 2,21-dithio-bis-isobutyronitrile, from which the latter is separated. The reaction is preferably carried out at 50 to 100 DEG C. in an inert solvent such as benzene, chlorobenzene or o-dichlorobenzene. In Example I, the azonitrile is added to a refluxing solution of sulphur in benzene, and the product is extracted with ether to remove the organic material.  The tetramethyl succino nitrile and 2,21-dithio-bis-isobutyronitrile are then separated by fractional crystallisation.  The 2,21-dithio-bis-isobutyronitrile is a vulcanising or accelerating agent for rubbers (see Group IV(a)).
