Abstract: 1429215 Linear particle accelerators C.G.R.- MEV 6 July 1973 [7 July 1972] 32358/73 Heading HID A linear accelerating structure comprises a sequence of cylindrical resonant cavities a 1 , b 1 , a 2 , b 2 , and a corresponding sequence of coaxially arranged annular cavities c 1 , c 2  disposed around the periphery of the cylindrical cavities and each coupled to an associated pair of adjacent cylindrical cavities. In the embodiment of Fig. 6, adjacent cavities a 1 , b 1  are coupled, via apertures s 1 , t 1 , through the annular cavity c 1 , while the alternate pair of cylindrical cavities b 1 , a 2  are coupled by apertures u 1 , v 1  in their common wall, direct coupling between cavities c 1  and a 2  being prevented by staggering the apertures u 1 , v 1  with respect to the apertures s 1 , t 1  (Fig. 7, not shown). In the embodiment of Fig. 11, which is made up of a sequence of identical structural components, every adjacent pair of cylindrical cavities is coupled by an annular cavity, and the cylindrical cavity common walls possess no coupling apertures. The annular cavities may have three re-entrant portions (Figs. 12 and 14, not shown), rather then the two exhibited in Figs. 6 and 11, and the coupling apertures s and t, instead of, as shown, being near the ends of the annular cavities, may be near their centres, and obliquely directed through the cylindrical cavity common walls (Fig. 13, not shown). The cylindrical cavities and the annular cavities may be provided with plunger tuning means (Figs. 9 and 10, not shown). Standing wave operation of the accelerating structure is referred to, and data on relative dimensions are given.

Abstract: 1,076,176. Telegraph receivers. GERAETEWERK KARL - MARX - STADT VEB. Aug. 14, 1964, No. 33369/64. Heading B6F. In a teleprinter having an automatic linespacing action coupled with carriage-return action, a partial line-spacing occurs if only a carriage-return signal is received and also partial line-spaces if a further signal is received during an actual carriage-return movement. As shown in Fig. 5, A, B represents a line of printing and the subsequent lines C, D; E, F &c. are at half-line-space intervals. When a carriage-return signal is received a half-line space is effected so the carriage travels, relative to the paper, in a diagonal direction B, N; if a signal is now received it is printed at Ox in half-line C, D and another half-line spacing occurs and if a still further signal is received, it is printed on line E, F at Px. This occurs until the carriage is fully returned and there is thus no possibility of an incoming signal printing on top of existing printing.

Abstract: 1391124 Telegraphy; isolating arrangements; switching circuits ITT CREED Ltd 20 July 1972 34015/72 Headings H3T and H4P An arrangement to electrically isolate a telegraph line 1, 2 from receiving apparatus and which provides output signals representative of positive, negative and zero current on the line comprises a ring modulator formed by two transformers 10, 12 with a source of switching pulses connected to a winding of one transformer and a threshold amplifier input connected to a winding of the other, with an input from the line connected to centre taps of the remaining windings of the transformers. Outside tape of the remaining windings may form diagonals of a bridge rectifier network 6-9. Outputs from a HF generator connected to terminal A is divided by cross connected toggles 14, 15, the output from 15B being applied through a constant current A.C. amplifier 16 to winding 11. In addition B outputs of 14, 15 are combined in a NAND gate 17 while A outputs are similarly combined in a NAND gate 18, outputs N1, N2 being illustrated at (N1, N2), Fig. 3 (not shown). Line signals applied to the transformers are switched by a signal applied to winding 11 hence a modulated output is obtained from winding 13 which after amplification in feedback amplifier 17 is applied to a threshold amplifier A18 providing a 0 when its input exceeds a threshold level, such as t, Fig. 3 (not shown), and a 1 when it does not. These signals are applied to B inputs of toggles 19, 20 which are respectively strobed by signals (N2, N1) hence provide respective outputs Y, X. When line current is zero, output on 18 is at a constant 1 hence toggles 19, 20 are set and a circuit given in Fig. 2 (not shown), connected to X, Y outputs of 19, 20 provide a Z signal in this condition. The threshold of amplifier A 18 may be adjusted by a variable resistor 22. A threshold stabilizing arrangement, Fig. 4 (not shown), may be incorporated.

The block copolymer may be prepared by coupling the components in solution in the presence of sulphur dichloride. The diene rubber may be a polymer of butadiene, isoprene or piperylene, optionally with styrene, acrylonitrile, acrylates, methacrylates and fumarates. The ethylene/propylene terpolymer may be derived from dicyclopentadiene, cyclo-octadiene, trivinyl cyclohexane, 2,5-hexadiene or 1,4-hexadiene as third comonomer. Preferably a solution of the rubber in the monomers is polymerized in bulk by heat or a free radi al initiator, e.g. a peroxide or azo compound, to 20 to 30% conversion of the monomers, and the product is suspended in water with the aid of hydrolysed polyvinyl acetate or hydroxyethyl cellulose and the polymerization completed. The products may be compounded with conventional stabilizers and lubricants and moulded. Examples describe the preparation of block copolymers by reaction of polybutadiene, butadiene/styrene and polypentenamer rubbers, toluene solutions with S 2 Cl 2  and adding a toluene solution of an ethylene/propylene/ dicyclopentadiene terpolymer, and graft polymerizing styrene and acrylonitrile thereon in bulk in the presence of dodecyl mercaptan, di-tbutyl-p-cresol, di-t-butyl peroxide and benzoyl peroxide, the polymerizations being continued in aqueous suspension in the presence of partially hydrolysed polyvinyl acetate, sodium dodecylbenzene sulphonate and sodium chloride.
