Patent GB-132117-A (GB)
IPC: F41B11/00
Abstract: 132,117. Armstrong, Whitworth, & Co., Sir W. G., Waddingham, W. H., and Taylor, A. Nov. 6, 1918. Launching torpedoes.-Relates to compressed-air apparatus for launching torpedoes from torpedo tubes, and consists in means controlled by the pressure in the compressed air reservoir for shutting off the reservoir when the pressure falls to a predetermined minimum during the launching operation. As shown, the launching valve between the reservoir 10 and the tube 12 com. prises a piston 11 which is normally kept against its seat 111 by the air pressure above it and by a spring 112. To launch a torpedo, a spring- controlled handle 20 is pulled, causing an arm 18 linked to it to press on a distance-piece 173, which opens a valve 19, venting off the air pressure above the piston 11. This piston is thereupon lifted by the pressure around its lower part, and compressed air passes to the launching tube. When the pressure in the reservoir 10 falls to the predetermined minimum, a diaphragm 15 subjected underneath to such pressure yields to a spring plunger 16, which rocks a lever 17 and removes the distance-piece 173 from between the arm 18 and the valve 19. This valve is then closed by its spring, and the pressure above the main valve 11, being no longer vented off, closes the valve, thereby shutting off the reservoir.

Title: Improvements in or relating to the manufacture of permanent magnets
Filed: 1940-08-21
Abstract: In the manufacture of an anisotropic permanent magnet, an iron base alloy containing 5-11 per cent of aluminium, 10-20 of nickel and more than 12 but less than 16, preferably 13.5-15.5, of cobalt, is subjected to the action of a magnetic field while cooling through a temperature range from 1200-1280 DEG C. down to from 700 DEG C. to 600 DEG C.  The alloy may also contain up to 10 per cent. of copper or up to 5 of titanium, but if both elements are present their total must not exceed 10 per cent. and the ratio of the aluminium content to that of the nickel is 1 : 2.  The cooling is effected at an average rate of 1/2  DEG C.-5 DEG C. per second, preferably 1.5 DEG C.-3.0 DEG C. for an alloy without titanium and at an average rate of 3 DEG C.-4 DEG C. for an alloy containing titanium.  The rate of cooling is selected according to the nickel and aluminium contents, being slower for the lower proportions of nickel and faster for the lower proportions of aluminium.  An ageing treatment may be applied to the alloy after its subjection to the magnetic field, e.g. by heating it to a temperature exceeding 450 DEG C. but not exceeding 750 DEG C. for 1-24 hours and the alloy may then be subjected to a second magnetic field of the same direction as the first field.  The alloy may be prepared as described in Specification 450,431 and cast, and in the cast condition may be subjected to the process described in Specification 478,127 to improve its machining qualities and machined before subjecting it to the action of the magnetic field. In an example, an alloy containing 52.5 per cent. of iron, 9 of aluminium, 17 of nickel, 15.5 of cobalt and 6 of copper is cooled from 1255 DEG C. down to 600 DEG C. at an average rate of 3 DEG C. per second in a magnetic field of 2,000 gauss or more.  After further cooling at any desired rate the alloy is aged at 550 DEG C. for 16 hours, cooled in still air to room temperature, and finally magnetized in a field of 1000-2000 gauss applied in the same direction as that of the first field. Specification 522,731 also is referred to.

Abstract: 275,360. Hoare, G. R., Hoare, H. J., Gibson, J. C., Hoare, D. E. E., and Sanna, F. May 27, 1926. Electric appliances; massage.-Massage rollers 28, 30 are carried by a casing 3 enclosing an electric generator, the armature 10 of which is rotated by a pinion 26 engaging a crown wheel 27 on the roller 28. A switching device is mounted on the end 4 of the casing to enable the path of the current to be varied. The armature spindle 11 carries two discs 13, 14, the disc 13 being connected directly to the spindle and carrying insulating projections 15. The disc 14 is insulated from the spindle and is connected to one end of the armature winding, the other end of which is connected to the spindle. Brushes 25 connected to a rod 24 engage the discs 13, 14 so that the current is short-circuited except when the projections 15 engage the corresponding brush 25. The rod 24 is connected to a metal plate 23 over which and in contact with which a pointer 22, Fig. 5, slides. The pointer is connected electrically to a rod 19 through a knob 21 as shown in Fig. 5. The knob 21 can be rotated to bring the rod 19 into contact with a metal strip 16, Fig. 4, which also makes contact with the casing 3. Rotation of the knob in the opposite direction brings the rod 19 under a contact 18, Fig. 4, and separates it from a stud 17 connected by a wire 33 to the spindle 11. The contact 18 is connected by a wire 34 to the bearing 32 of the roller 30. When the rod 19 is in contact with the metal strip 16 the current flows from the armature to the casing 3 and through the body to the rollers 28, 30. When the rod 19 is in the central position the casing 3 is cut out of circuit and the current can be carried to an additional electrode connected by a wire to the rod 24 and thence to any part of the body and back through the rollers. When the rod 19 separates the contacts 17, 18 the current passes from the roller 28 through the part of the body being massaged and back through the other roller. The end 4 of the casing can be rotated in either direction to alter the timing of the interruption of the current by the disc 15 relatively to the maximum E.M.F. generated.
