Title: Manufacture of Internally Ribbed Tubing
Inventor: BRADSHAW HARRY OSBORNE
IPC: B21C37/20
Filed: 1967-02-16
Abstract: 1,162,752. Swaging. TUBE PRODUCTS Ltd. 22 March, 1968 [16 Feb., 1967], No. 7465/67. Heading B3H. A metal tube with an internal helical rib is made by swaging a plain bore tube 1 on to a helical mandrel 2 using rotary swaging dies 3, whilst permitting the tube and mandrel to rotate relatively to the dies at speeds different from each other. This causes the tube to unscrew itself from the mandrel as swaging proceeds. The opposed swaging dies 3 are mounted for radial reciprocation in a rotary head (10), Figs. 3, 4 (not shown), driven by an electric motor (6), Fig. 2 (not shown). The dies are backed by hammers (12) carrying hardened rollers (13) which engage with a ring of stationary rollers surrounding the head. During swaging the rotating dies 3 alternately grip and release the tube thereby causing its rotation. Mandrel 2 has a shank 4 gripped by spring-biased friction blocks 5 which allow the mandrel to rotate but at a speed lower than that of the tube 1. The clamping pressure on the blocks 5 is adjustable for varying the rate of feed of the tube through the swaging machine. The ends of the helical portion 2 of the mandrel may be tapered.

Abstract: 140,595. Yates, D. H. March 26, 1919. Cylinders.-In steam-engines of the " uniflow '' type, an automatic relief valve is combined with the manually-actuated stop valve for putting the extra-clearance space into communication with the cylinder. Within the valve-chest 1, formed or mounted on the cylinder 2, is a cylindrical stop valve 6, moved to and from the seating 4 by means of a screw 17 and a hand-wheel 21. The screw 17 is formed with a spherical end held in a spherical seat within members 19, 20 by a cap 16.

Abstract: Acetone-soluble copolymers of acrylonitrile and vinylidene chloride are dry-spun into an evaporative atmosphere and the freshly extruded fibres are stretched from 75 to 300% at from 15 DEG -40 DEG C. Preferably, the fibres are stretched 100-300% at ordinary room temperature.  Stretching may be effected in air or in water or other non-solvent for the fibres, which may contain a textile lubricant. The fibres may subsequently be stretched a second time from 500-2,000% of the length immediately before this second stretching, especially from 700-1,500%, at not less than 95 DEG C., e.g. in hot air, steam or hot water, preferably in saturated steam at superatmospheric pressure.  Between the two stretching operations the fibres may be collected and stored on bobbins.  After the hot-stretching, the fibres may be annealed by heating while they are free to contract, e.g. in water at 90 DEG -100 DEG C., or in saturated steam at atmospheric pressure.  Fibres so treated have high dimensional stabilities to wet and dry heat. Specifications 643,198, 674,323, 709,995, 849,029 and 897,697 are referred to.

Abstract: 686,357. Firearms. BREVETS AEROMECANIQUES SOC. ANON. April 9, 1951 [April 15, 1950], No. 8229/51. Class 92(ii) Relates to self-loading firearms of the kind in which the breech-block 1 can be retracted by a longitudinally guided slide which is mounted in a casing rigid with the firearm support 5; the firearm recoils with respect to this support. According to the invention one of the abutment parts 9 or 10 of the slide and breech-block respectively is retractable with respect to the part on which it is mounted so as to enable the firearm and breech-block to be removed frontwardly away from the support. In the construction shown the firearm as a whole, including the breech-block 1 recuperator spring 2, and breech casing 3, is slidable on the fixed support 3 upon which the cocking device is mounted. The cocking device comprises a guide 5 for a slide 6, the latter being fitted with a spring- controlled pivoted abutment 9. In use the slide 6 is pulled rearwardly by a cable 7 against the action of a spring 8, and the abutment 9 engages an abutment 10 on the breech-block to withdraw the breechblock to its cocked position. When there is no pull on the cable 7 the spring 8 holds the slide in the forward position and the abutment 9 is then depressed by a member 13 rigid with the support S.

A mercury arc rectifier system comprises more than one path 1, 4; 2, 5 or 3, 6 for the load current through the rectifier 10, the paths 1, 4 &c. being in parallel and of unequal impedance, the proportions of the load current passing through the paths 1, 4, &c. being adjustable by means of grid control applied to the anode in one or more of the parallel paths 1 &c. The anodes 1, 2, 3 are grid controlled by the grids 11<SP>1</SP>, 11 2 , 11<SP>3</SP> which are suitably biassed by means of the phase-shifting grid transformer 17<SP>1</SP>, 17<SP>2</SP>, 17<SP>3</SP>, the circuits of the anodes 4, 5, 6 including regulating chokes 151, 15<SP>2</SP>, 15<SP>3</SP>. When the phase-shifting transformer is arranged to prevent the anodes 1, 2, 3 from firing only the anodes 4, 5, 6 will pass current, the regulation being that given by the chokes 151, 15<SP>2</SP>, 15<SP>3</SP>, which may be a desired maximum. If the phase-shifting transformer is now arranged for zero firing delay only anodes 1, 2, 3 will pass current the regulation now being that inherently provided by the reactance of the transformer 121, 12 2 , 123. At an intermediate position of the phaseshifting transformer a regulation value between these two will be obtained. Thus the phaseshifting transformer becomes a regulation controller but it has no control at no load. Any known form of grid control may be used.
