Title: Improvements in methods of manufacturing metal powder
IPC: B22F9/04
Filed: 1922-02-07
Abstract: 197,031. Shimadzu, G. Feb. 7, 1922. Ball and like mills.-A chemically-reactive fine lead or other metal powder is produced by rotating a vessel charged with lead balls or pieces of metal so as to cause abrasion of the balls or pieces between each other and the inner surface of the vessel. Hard metal balls may be introduced into the vessel with the piece of lead. A hollow cylindrical iron vessel with feed and discharge openings at its ends may be used. An air blast from a blower within the vessel blows the fine powder out of the discharge opening into a collecting-chamber; or the vessel may be pierced all over with small holes through which the fine powder is blown out. Instead of air, dry carbonicacid gas, nitrogen, &c. may be used to discharge the metal powder from the hollow cylinder, and the velocity of the air or other gas may be regulated to determine the fineness of the powder removed from the cylinder.

Title: Improvements in or relating to padlocks
IPC: E05B67/00
Filed: 1935-02-05
Abstract: 451,246. Padlocks. CASTELL, J. H., 42, Tavistock Square, London. Feb. 5, 1935, No. 3726 [Class 44] Padlocks of the kind comprising two parts A, B pivoted about a connecting spindle D are locked against relative movement in the closed position by one or more locking pins E movable in bores 7, 8 parallel to the spindle D, the ends of these pins being brought flush with the division 18 between the parts A, B by the axial movement of a key inserted into an enlarged bore 12 in the member B. The key may act directly on the pins E or through set pins F. The spindle D is pinned to the member B and has a reduced portion 5 engaged by a set screw in the member A, a smaller set screw in the reduced portion acting as a stop to prevent complete rotation. Integral with or secured to the end of the spindle D is an enlarged head 10 having extensions 13, Fig. 2, extending across the annular gap in the bore 12, these extensions co-operating with corresponding recesses 16, Fig. 5, in the key to ensure that the key is inserted in the correct position. Bits 15 on the key of different lengths depress the pins E when the key is inserted and different padlocks may have pins of differing lengths requiring keys with correspondingly different bits 15. Alternatively, as described in Specification 189,825, [Class 44], all keys of a group of padlocks have the same configuration of bits but individual locks and keys are provided with interengaging incised and cameo letters or figures s, s1 formed on the ends of the head 10 and of the bore in the key. A key having the letter cut away, or its surround if the letter is incised in the key, consequently acts as a master key for the group. To prevent an ordinary key from being readily filed to act as a master key the letters or the surrounds of incised letters may have hard steel pins plugged or screwed in. The shackle pin C may be fixed to one arm or a divided pin may be used with its two halves fixed to the respective arms. Instead of an annular groove 5 being formed in the spindle D a segmental slot may be cut in it so that a second set screw to act as a stop is unnecessary.

Title: Improvements in or relating to receiving apparatus for high frequency electric signals
IPC: H04B15/06
Filed: 1926-02-10
Abstract: 247,564. Westinghouse Electric & Manufacturing Co., (Assignees of Beers, G. L.). Feb. 10, 1925, [Convention date]. Void [Published under Sect. 91 of the Acts]. Thermionic heterodyne receivers, amplifiers, and detectcrs.-A supersonic heterodyne receiver is provided with a balanced amplifier 2, the output of which is fed, together with local oscillations from the source 4, to the grid of the first detector 8. The grid circuit of the detector S is tuned by a condenser 15 linked mechanically to the condenser 3 for tuning the loop aerial 1. The circuits of the valve 2 may be balanced by a reversed coil 16 coupled to the plate coil 6 and connected through a small condenser 17 to the grid. Alternatively a small condenser may be connected between the plate of the valve 2 and one end of the loop aerial, the other end of the aerial being connected to the grid, and its midpoint to the filament. Either of these arrangements prevents self-oscillation of the valve 2 and also dissociates the aerial from the local oscillations produced by the source 4. The supersonic beats are amplified by one or more valves 11 and rectified in the second detector 12. The selectivity afforded by the tuned amplifier 2 reduces interference from. undesired signals, particularly signals which, in heterodyning with harmonies of the local frequency, would produce beats suitable for amplification by the amplifier 11.
