Title: Halogenated vinyl ether polymers
IPC: C08F8/20
Filed: 1946-11-18
Abstract: Rubbery vinyl ether polymers are halogenated between 5 DEG  and 100 DEG  C., preferably between 20 DEG  and 60 DEG  C., in solution in an organic solvent inert to the halogen at least to the extent that the polymer is gelatinized and in the presence of sufficient of a stabilizer against depolymerization by heat to give a rubbery product on removal of the solvent after halogenation.  Specified solvents are chloroform, trichlorethylene, carbon tetrachloride, a - or b -tetrachlorethane, chlorobenzene and o-dichlorobenzene. Stabilizers listed include thiosemicarbazide, benzyl tetrasulphide, dehydrothio-p-toluidine, allyl polysulphide, n-butyl monoethanolamine polysulphide, thiourea, b -naphthylamine, phenyl-b -naphthylamine, ethyl-a -naphthylamine, 4,41-diamino-diphenyl aniline, p-hydroxy-N-phenyl morpholine, b -naphthol, phenyl-b -naphthol, 4-tert.-butyl phenol, 4-tert.-m-cresol, 2:6-dichloro-4-tert.-amyl phenol and sodium sulphide and polysulphide.  Specified polymers include rubbery polyvinyl ethers, e.g. polyvinyl methyl ether, isopropyl ether, n-butyl ether and isobutyl ether, and copolymers obtained by copolymerization of vinyl ethers with one another or with other vinyl compounds, e.g. acrylonitrile.  Preferably, the free halogen is employed in solution in an inert organic solvent, e.g. carbon tetrachloride, although compounds yielding halogens may also be used, e.g. calcium and sodium hypochlorites.  The halogenated polymers may be modified by addition of plasticizers, agents absorbing ultra-violet light, basic stabilizing agents, metal or metal oxide vulcanizing agents and organic and inorganic fillers; specified are chlorinated diphenyl, chlorinated paraffins, dibutyl phthalate, dibutyl sebacate, phenyl salicylate, urea, phenoxy-propylene oxide, zinc, zinc oxide.  The rubbery products may contain 2-30 per cent halogen and have reduced tack, solubility and flammability, those containing 20-30 per cent combined halogen being thermosetting.  Specific physical properties may be obtained by using mixtures of different halogenated polyvinyl ethers or of the same polyvinyl ether halogenated to different degrees.  Specification 482,512 is referred to.

Abstract: 394,585. Manual exchange systems. STANDARD TELEPHONES & CABLES, Ltd. and HARDWICK, J. R., Connaught House, Aldwych, London. Dec. 5, 1932, No. 34354. [Class 40 (iv).] Calling and supervisory arrangements between two stations, e.g. a police box and a police station, comprise a calling lamp at the box and a lamp at the station which is signalled in a distinctive manner from the box until the call is answered or cancelled. To call the box B, the operator at police station P plugs in and sends momentary ringing current to operate relay B which is followed by C and E. On cessation of ringing, B and C relapse but E holds over D which also pulls up. A relay interrupter group G, H, I intermittently loops the line to flash line lamp S at the police station, it being assumed that the operator has unplugged while attending to other calls (the cord lamp would, otherwise, be flashed). The lamp KL at the box is, as shown, lit by relay E but it may be flashed by interrupter relay I. When the call is answered, A pulls up, disconnects the relay equipment, and lamp S glows steadily. The lamp KL and interrupter group can only be restored to normal by operating relay F which may be done by key K accessible only to the police (the public may use the box) or by sending a pulse of ringing current from the police station to operate B and C. If the public use the box during a police call from the station, the interrupter relays are disconnected from the line by relay A until the public call is terminated. Operating current may be derived from D.C. or A.C. mains.

Abstract: 173,756. Seguin, A. Jan. 8, 1921, [Convention date]. Impulse and momentum speed indicators.-Comprises a main member revoluble at a speed proportional to that to be measured and a comparison member having a definite free motion of its own. The main member is a snail-cam 9 secured on a shaft 1 which rotates at the speed to be measured, while the comparison member is a spring 24 bearing against the cam at its free end. An arm 15, which is normally rotated in the reverse direction to the cam by a frictional device from a pinion 12 in gear with a pinion 11 on the shaft 1, is driven in the opposite direction by a stud 27 on the end of the spring 24, during the free motion of the spring on leaving the cam, through an angle constant for all speeds, the end positions of the oscillatory motion of the arm 15 determining the speed. The shaft 13 carrying the arm 15 has at the other end an arm 16 having projecting studs 17, 18, an angular distance a apart, which may be made equal to the angle between the end positions of the arm 15. The indicating-pointer 20, mounted frictionally to allow of its taking up a definite position, is actuated by an arm 23 on the same shaft which strikes against one or other of the studs 17, 18. Alternative means are described for obtaining the constant movement of the arms 15 by use of a spring or of pulleys and belts. A balance-wheel with a spiral-spring may replace the spring 24. Indication may be effected optically by the passage of the stud 27 rendered luminous past a graduated slit.
