Patent GB-110634-A (GB)
Title: Improvements in or connected with Ships' Telegraphic Apparatus.
Inventor: CHADBURN WILLIAM
IPC: B63H21/22
Filed: 1916-11-15
Abstract: 110,634. Chadburn, W., and Chadburn, W. R. Nov. 15, 1016. Mechanical telegraphs.-In ships' telegraphie apparatus in which a transmitter is mounted on a stationary place on the ship, and a receiver is carried by a revoluble turn-table or platform, a transmission means is provided whereby the turning of the turntable will have no effect on the pointer of the receiver. Fig. 1 shows a turn-table 1 rotatable about a standard 2 and carrying a receiver 10. The transmission shaft 8, making one revolution for each movement of the pointer of either transmitter or receiver over one dial division, enters the fixed base 5 of the table 1, and conveys its motion by bevel-wheels 9, shaft 11, bevel-wheels 12, telescopic shaft 13, 14, (the parts of which are relatively non-rotatable), bevelwheels 15, and shaft 16 to the receiver 10. The receiver 10, shown in cross-section in Fig. 5, contains a Geneva-stop device, the disk 21, Figs. 1<b> and 5, of which carries a pointer 32 and the disk 20 of which is driven by bevel-wheels 34, 35 from the shaft 16. The bevel-wheels 12 give the shafts 13, 14, 16 a two-to-one motion relative to the shaft 8, and the bevel-wheels 34, 35 reduce this motion so that the disk 20 revolves at the same rate as the shaft 8. The effect of the shaft 16 having twice the angular motion of the disk 20 is to limit the movement of the latter, when the table 1 rotates to its extreme limits, to positions indicated by the radial lines 24, Fig. 1<b>, thus preventing the movement of the disk 21 and pointer 32 by motion of the table. Included 'in the mechanism are a gong 18, universal coupling devices 43, a roller rest 46 for the shafts 13, 14, and a ball-bearing at 44 for the shaft 16. An electric lamp, partly or wholly obscurable, is located in both transmitting and receiving instruments.

Title: Improvements in or relating to magnetic brakes
IPC: B61H7/08
Filed: 1924-07-08
Abstract: 240,913. Chopra, N. D., and Bullen, F. J. July 8, 1924. Electromagnets.-An electromagnetic brake, in particular a skid brake, comprises a plurality of independent pole pairs in a unitary structure, the poles of each pair being disposed transversely of the length of the brake and the pole pairs being arranged along the length. The pole pairs may be separately energized and may be adapted separately to engage the rail or other co-operating surface. Fig. 1 shows a skid or track brake comprising three electromagnets or pole-pairs 5, 6, 7, mounted in a frame 4 and adapted to engage a rail 8. The coils 9, 10, 11 of the magnets are connected to a controller having contacts 14, 15, 16, 17 whereby the magnets may be successively energized in the order 5, 6, 7, to graduate the braking effect. The pole pairs of the magnets may each be slidably mounted on the frame 4 so that they engage the rail successively. The electrical connections may instead be arranged so that the magnet 6 is first energized, and on further movement of the controller the magnets 5 and 7 are simultaneously energized. Bronze or other material commonly used for lining brakes may be fitted to the magnets as described in Specification 240,912.

The alloy may also contain Mg 0.03-0.4 per cent.  The Cu, Ni and Ti constituents may be added to a Zn-rich melt in the form of a Cu-Ni-Ti alloy hardener which may contain Cu 45-90 per cent, Ni 8-40 per cent and Ti 2-15 per cent and which may be made by melting Cu, adding Ni and then adding commercially pure Ti while protecting the melt with an inert atmosphere.  In forming the Zn alloy, commercially pure Zn is melted, the Al is added and the hardener alloy is added while the melt is at a temperature between 1100-1300 DEG F.  Alternatively the Al may be added in two equal portions, one before and one after the hardener.  The melt may then be fluxed, e.g. with ammonium chloride after which Mg may be added if required.
