Inventor: GOSSELAIN PIERRE ALEXANDRE
IPC: C08G2/00
Filed: 1962-05-24
Abstract: A high molecular weight polymer of carbon sub-oxide is produced by liquid-phase irradiation of a solution of carbon sub-oxide in a halogenated hydrocarbon solvent. The irradiation may be effected by means of g  rays from fission products or from a cobalt-60 source, or by means of X-rays, U.V. rays or electrons from an electron accelerator.  The solvent may be methylene chloride, chloroform, carbon tetrachloride, ethyl bromide or heptyl bromide. The irradiation is preferably effected at - 50 DEG  C. to + 50 DEG  C.

For operation above 150 MHz, the vertical deflection means is delay line apparatus as in U.S. patent Specification 3,694,689. Fig. 1 also includes glass or ceramic envelope 12, phosphor screen 14 with A1 coating 18, focussing anodes 28, 29, mounting and shielding member 50 at near ground potential shielding the vertical plates from h.v. p.d.a. anode 54, and scan expansion mesh 58 ensuring full overlap operation of the two beams. Arcuate configurations of plates 36, 37 corrects vertical trace bowing by the mesh (Fig. 2, not shown). Additional control is possible by variable potentials to compensator plates 70, 71 to compensate for part tolerances and misalignment. Plate 75 prevent interference between plate pairs 32, 33, and intergun shield 80 prevents electrostatic field interferences and minimizes capacitance between plates 40, 41 to reduce h.f. cross-talk. Shield 80 with shields 82, 84, 85 corrects battery distortions, especially keystone type while further correction may be provided by arcuate exit edges on plates 40, 41. In Figs. 3, 4, 5 (not shown), slotted half-discs (120), (121) insulatively attached to shield (80) isolates plates 40, 41 from p.d.a. anode 54.

Filed: 1926-08-24
Abstract: 267,401. Dap - Motor - Patent - Ges. July 3, 1926, [Convention date]. Revolving-cylinder pumps.-In an engine or pump comprising curved or straight continuously rotating cylinders 1 with their pistons 2 alternately held stationary and moved through twice the stroke, the pistons in the stationary position are locked against forward as well as backward movement by an oscillating member pivoted to a stationary part of the engine and coacting with both moving parts. The pistons are connected with a ring i having teeth m and the cylinders with the hub d having teeth n. A lever on a fixed pivot engages the two sets of teeth., shown in Fig. 2, and so long as the lever h bears on the concentric parts of the teeth n the pistons are locked against rotation in either direction. The forward movement of the pistons is obtained by means of a planet pinion 5 and connecting rod 13 with a spring connection 14 to the piston carrying frame. Specification 242,280, [Class 110 (ii), Rotary engines &c.], is referred to.

Title: Improvements in or relating to telephone and like electric cables

Filed: 1930-07-10
Abstract: 356,376. Telephone cables. HACKETHAL-DRAHT - UND KABEL - WERKE AKT.-GES., Staderlandstrasse, Hanover, Germany. July 10, 1930, No. 20972. Convention date, July 10, 1929. [Class 36.] To compensate the pair to phantom cross-talk couplings in a telephone quad, a length of the quad is so stranded that only one core of one pair of conductors 2, Fig. 2, E, is maintained adjacent the other pair 1. During the stranding of the compensating length the twist of the pair 2 is stopped, but the natural twist of the pair 1 and the lay of the quad is preferably continued. A fractional part of a run of cable, such as one of a number of lengths in series, may be formed as above with couplings which compensate for the total couplings of the remainder of the run, but preferably the couplings of each length are measured continously on the stranding machine and compensation is set into operation as soon as the couplings reach a predetermined value. To avoid the formation of pair to pair couplings due to the pair 2 of the compensating length being distorted into an oblique position, as shown at G, Fig. 2, the pair 2 is oscillated between the positions A, B through E. Fig. 1 shows a stranding machine for carrying out the invention; each pair of heads a, band c, d carrying core spools run round each other to strand the cores to pairs, whilst both pairs of heads rotate about a common axis to give the quad stranding. A predetermined location of the cores in the stranding nipple e and thus in the quad is obtained by passing the cores through adjustable guides f, g, between the heads and the stranding nipple, the guides being normally in positive connection with the heads belonging to the same pair, but may be moved independently by devices h, i. The pairs of heads a, band c, d may be locked in any position in relation to the whole system in order that the twisting of a pair of cores may be stopped when it is desired to set the compensation into operation. To prevent displacement of the cores with reference to each other, the pairs before quadding and the quad after stranding may be wound with paper strips or threads.

Abstract: 223,200. Wolders, C. T. Oct. 11, 1923, [Convention date]. Angular bending; coiling; mandrels.- In a tube-bending machine of the type in which the tube is secured at one end to a rotatable former and drawn thereby over a positively rotated internal mandrel provided with rollers, the rollers are arranged in openings in a freely rotatable container, and rotation is effected by a positively-driven spindle engaging the rollers. The tube is passed over a mandrel 6 secured at one end to a bed 22 and supported by rollers 31, and is clamped at 5 to a grooved former 3 rotated on a shaft 2. The mandrel consists of a roller container 11 and guide 16, which are rotatably mounted on a shaft 8 rotated by an electric motor 7. The container has oblique slots to receive a set of conical rollers 14 and a set of barrel-shaped rollers 15, which engage with and are rotated by the tapered spindle 9 carried by the shaft 8, the container being carried round by the rolling motion of the rollers. The shaft is given an axial movement so as to free the rollers when inserting or removing the tube. In coiling a tube the former 3 is replaced by a helically-grooved former, and the bed and the supports carrying the rollers 31 'are laterally traversed by screws 28 rotated by spur and bevel gear from a shaft connected to the shaft 2. In forming spirals a grooved former co-operates with a mandrel which together with the supports of the rollers 31 is movable vertically, and in forming conical spirals the mandrel is given a lateral and also a vertical traverse. The mandrel is lubricated by a pump driven by the motor and supplying oil to a duct in the sleeve 18 which communicates with the container 11.
