Patent GB-181807-A (GB)
Title: Improvements in or relating to automatic firearms or the like
IPC: F41A3/46
Filed: 1921-03-17
Abstract: 181,807. Marga, U. A. March 17, 1921. Breech actions, sliding barrel and breech-block. - Relates to automatic guns of the short barrel-recoil type having on the breech-block a locking-member operated to the locking-position by the firing-pin. According to the invention, the locking-member is a sliding bolt adapted to be displaced normally to the axis of the gun by a rebound action firing-pin. In Fig. 1, the invention is shown applied to a gun having a barrel 5 which rotates during its short recoil. The laterally sliding locking-bolt 24, mounted in the breech-block 4, is moved outwards by the advancing firing-pin 9 to engage a hooked catch 23 on the barrel. The bolt 24 and catch 23 are disengaged, to unlock the breech, by rotation of the barrel 5 caused by a stud 7 on the barrel engaging a helical slot 8 in the casing. Firing is effected by an inclined sliding hammer 14, which, during the opening of the breech, bears against the side of the breech-block and acts as a brake. In the modification shown in Fig. 3, the barrel 5 does not rotate, the bolt 17 being moved to its unlocking position by inclined bearing surfaces between the bolt and the locking-catch 23 on the barrel.

Title: Improvements in or relating to an electrolyte for electrolytic shaping of a workpiece containing niobium, tantalum and/or vanadium
IPC: B23H3/08
Filed: 1963-03-04
Abstract: A metallic workpiece containing as a major component V, Nb, or Ta is electrolytically shaped by flowing between the workpiece as anode and a cathode an electrolyte having a concentration of at least 0.007 N of an ionizing non-hydrolizing bromide of a positive ion above U on the electromotive scale together if necessary with a soluble chloride to provide adequate conductivity.  Typically anode current densities of 500 to 8000 A/Sq. inch are employed the electrolyte temperature being 100 to 120 DEG F.  If bromide alone is used, e.g. of Na, K, Ca or NH4, a concentration of 0.018 N should be provided, while if supplemented by chloride the bromide concentration may be 0.007 N with a chloride concentration of approx. 0.25 N, e.g. 0.8 g Na Br with 15g NaCl per litre.

Abstract: 990,492. Automatic speed control systems. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. April 23,1963 [March 6, 1963], No. 8945/63. Heading G3R. In a flying tool control system having a circular saw 7 carried by a bar 13 mounted between cranks 15 to cut a moving tube 3 issuing from a tube mill, the speed of the cranks is controlled firstly in accordance with the speed of the moving tube during cutting, and secondly cyclically during the remainder of the revolution of the crank; the relative effectiveness of the two control components being adjustable to vary the cut length. The field 25 of a Ward Leonard set driving the cranks is controlled in accordance with the difference between signals from a tacho generator 31 driven from the tube mill, and a tachogenerator 29 driven from the WL set. In addition a further control signal dependent on the position of the cranks is derived from a selsyn 47 driven from the WL set and energized from a constant frequency generator 43 having its field energized according to tube speed by tachogenerator 31. This output signal from the selsyn is processed in a phase sense discriminater 49 and subtraction unit 57 to provide a cyclically varying signal, a proportion of which is picked off by potentiometer 61 to determine the crank speed for the remainder of the revolution, and hence the cut tube length. The range of resulting control signals relative to the steady tube speed signal are illustrated in Figs. 6,7 (not shown).
