Title: Improvements in or relating to cellular thermoplastic polymers
IPC: C08J9/04
Filed: 1964-08-26
Abstract: A process for preparing cellular thermoplastic polymers comprises heating under pressure a composition comprising a thermoplastic polymer, an azido cross-linking agent and a blowing agent, to a temperature above the softening point of said composition and sufficient to release the gas from said blowing agent and to effect azido modification of said polymer and then reducing the pressure to allow expansion of the composition to form the desired cellular thermoplastic polymer.  The reduction of the pressure may be carried out in more than one stage. Thermoplastic polymers specified are polypropylene, polyethylene, copolymers of ethylene and propylene, polystyrene and polyvinyl chloride.  An elastomeric polyolefin such as an ethylene-propylene copolymer rubber or polyisobutylene may be included in the composition. In the examples, decamethylene disulphonylazide, tetramethylene bisazidoformamide, dodecamethylene disulphonylazide, 4,41-diphenyl disulphonyl azide and a chloropolysulphonazid are used as cross-linking agents and azobis-formamide and methylene chloride are used as blowing agents. The foamed and cross-linked thermoplastic polymer may be formed into sheets or shaped articles at high temperature by pressing between plates or in a matched set mould.

Title: Improvements in or relating to the sizing of artificial silk
IPC: D06M15/263
Filed: 1935-12-20
Abstract: Artificial silk threads are sized by treatment with aqueous dispersions of one or more esters of polymerized acrylic or methacrylic acid containing also glue.  The methyl or ethyl polyacrylic or polymethacrylic esters may be used.  The artificial threads may be sized in skein or warp form.  They may be of cellulose acetate or cuprammonium regenerated cellulose.  The sizings are fast to washing and dyeing and need not be removed. The sized threads do not stick, and a close warp may be woven satisfactorily.  For warp sizing there may be used 100--150 grams per litre of a composition consisting of 6 parts glue, 56 parts of a 25 per cent aqueous dispersion of a methyl ester of polyacrylic acid, and 38 parts of water.  The sizing is effected at 60 DEG  C.  For skein sizing a somewhat lower concentration is used and the temperature may be 30--40 DEG  C.  The material may subsequently be centrifuged, and dried, with frequent shaking during the drying step.  The Specification as open to inspection under Sect. 91 comprises also the addition to the sizing bath of other organic colloids instead of glue.  This subject-matter does not appear in the Specification as accepted.

Filed: 1962-09-18
Abstract: 990,564. Selective signalling systems. HEWLETT-PACKARD CO. Sept. 18, 1962, No. 35577/62. Heading G4H. [Also in Division H3] To measure accurately the number of clock pulse periods in a given time period the partial pulse periods at the beginning and end are expanded in time and used to alter the integral number of pulses counted. As shown in Fig. 1 the beginning and end of the given time period may occur at or between pulse peaks so that measurement of the times 5, 6 is necessary. In the latter case this is achieved by measuring time 7 and taking its complement. Timer 9 applies a start pulse to lead 12 to cut off normally-conducting transistor 15 until the occurrence of the next clock pulse on terminals 10. A time-delay expander 35 comprises a one-shot asymmetrical oscillator in which the time taken to charge capacitor 23 in the one sense is multiplied by a factor of say 10 to charge the capacitor in the opposite sense. The time 5 results in a tenfold duration of potential at terminal 33. Gate 41 therefore applies an appropriate number of clock pulses to a binary-coded decimal counter 43. Meanwhile complete clock pulses are entered through 37 to advance the main counter 39, the first pulse being ignored. At the end of the prescribed time a stop signal on lead 14 operates a like time delay expander 47 the resulting count being complemented before application to counter 43. One or more carries may be made to the counter 39 via gate 45, the residue in 43 giving the first decimal place of the count.

Abstract: 1,187,150. Superconductors; lasers. COMMISSARIAT A L'ENERGIE ATOMIQUE. 7 Aug., 1967 [7 Sept., 1966], No. 36231/67. Headings H1C and H1K. [Also in Division G6] Energy is transferred to the plasma inside the chamber 6 from the magnetic field in the annular chamber 8, produced by the current, J, in the superconducting layers 9, 9a. The transfer is effected by raising the temperature of the layer 9a, thereby changing its state from the superconductive to the normal and interrupting the current J. The resultant potential difference across the ends of the chamber 6 produces an arc in, and a radial contraction of, the plasma column due to the pinch effect. The layer 9, 9a is formed of an alloy of niobium and tin and is brought to the superconductive state by the introduction of liquid helium through the apertures 13. The current, J, is produced in 9, 9a by the rotating field of coils 12 as described in Specification 1,187,149. To interrupt J, the transition of 9a is effected by the heating resistance, 10, and by a magnetic pulse produced in solenoid 11. In a modification, Fig. 2, the chamber 6 contains a laser rod 16 which is pumped by the plasma produced in a gas-filled tubular casing 17 surrounding the rod. An apertured end-plate 4 provides an emission window.

An apple pushed on the prongs 18 of a rotated hollow mandrel 16 is peeled by a spring- pressed knife 38 moving in an arc along the apple and is cored by a semi-circular coring tool 20 which slides in'over the pronged mandrel end 17 until the core is cut right through and the apple is transferred to the corer 20, where it is held by projections 44 thereon. The peeling knife 38 and the corer 20 are connected to a sliding carriage 6 which is oscillated by a connecting rod 12 from a lever 14 rocked by cams on a hand rotated cam wheel 57. When the carriage reverses (to the left, Fig. 1) the coring tool 20 with the apple also reverses until an abutment 45 reaches a fixed abutment 46 so that the lever 21 swings up so that the apple is pressed against a fork 47 to discharge the apple. During this reverse of the carriage the peeling knife swings up out of the way by rotation about the pivot (27, Fig. 2, not shown). The core still held on the mandrel 16 is pushed off by a rod 19. The peeling knife 38 is shaped with guide lugs. The thickness of the peel is adjusted by setting the guard plate 39 nearer or further from the knife edge. The arcuate movement of the peeling knife is derived from fixed pins (42, Fig. 4, not shown), rocking a pin 29 as the carriage travels to the right, the knife being connected to the pin 29 as in Fig. 3 (not shown).
