Abstract: 367,711. File and rasp cutting; serrating saws &c. SMITH, H. G., Majestic Hotel, Kings Cross, Darlinghurst, near Sydney, Australia. July 27, 1931, No. 21423. [Class 83 (ii).] A machine for cutting files comprises a fixed headstock and sliding tailstock with chisel tools, radially housed in the headstock, working in opposed relation so that the necessity for a blank-supporting bed is eliminated. The machine is also applicable for serrating saws &c. A blank 15, the tang of which is held by a chuck on the tailstock 12, is supported at the tip by a socket 14 which slides in the headstock 11 and may be drawn towards the tailstock by weight and pulley or coupled thereto by a bar 116. The chisel tools 110, disposed radially in angular relation to the blank, are carried by plungers 48 slidable in the fixed housing, the number depending upon the contour of file to be cut, e.g. three chisels are used for cutting triangular files. Compression springs 50 force the chisels towards the blank and the blow required to make the teeth is obtained by retracting the chisels against the spring pressure and suddenly releasing, this is achieved by a rotating interrupted cam 44 engaging lugs 109 on the plungers 48. The springs 50 are contained in telescopic casings 51 which terminate in piston elements, these slide in cylinders 53 and enable the compression in the springs to be varied according to the blow required, automatic control may be effected either hydraulically, as shown, or entirely mechanically; in the former method fluid pressure from a pump and accumulator is transmitted through a non- return valve 64 and hand pressure-adjusting device 61, fluid pressure to the pistons controlling the springs being automatically varied by a cam bar 70, Fig. 3, moving with the tailstock, operating a plunger 71 in a second pressure-adjusting device 74. The interrupted cam is rotated through a clutch by a belt pulley 19, the clutch being automatically thrown out of engagement at the end of each complete operation by a trip gear 25, 26 actuated by a stop 29 on the tailstock. The tailstock is fed, continuously or intermittently, towards the headstock by screw and split nut gear and retracted by a hand-wheel 107. In cutting round files the blank may be given a stepped rotation by a pawl-and-ratchet gear 31, 32 operated at the end of each return of the tailstock by a cam 34, Fig. 1. A reversible tailstock having two file-holding chucks may be used.

Abstract: 398,327. Converting. AKT.-GES. BROWN, BOVERI, ET CIE, Baden, Switzerland. Aug. 3, 1932, No. 21750. Convention date, Aug. 3, 1931. [Class 38 (ii).] Relates to an arrangement for interchanging power between D.C. networks. Associated with the networks a, b and c, d respectively, are pairs of vapour discharge devices GI, GII, and GIII, GIV, the anodes of which are connected to polyphase windings Q1, Q2, and Q3, Q4 of a transformer T that has an energizing winding P fed from a three-phase network N. The secondary star-points and cathodes of each pair are cross-connected (e.g. the star point of Q1 is connected to the cathode of GII). Discharge devices GII and GIV are provided with grid control to enable them to function as inverters, and the grid control is such that the discharge device associated with the network supplying power does not conduct current. If power is flowing from a, b to c, d, D.C. is converted to A.C. by means of GII and is fed via the windings Q2, Q3 and the rectifier GIII to the D.C. circuit c, d. If the D.C. circuits have a common conductor then the two discharge devices associated therewith may have a common containing vessel and cathode. All the discharge devices may have control grids, and regulation may be obtained by an adjustment of the phase of the grid potentials. The arrangement also permits of interchange of power between the A.C. network N and the D.C. networks a, b and c, d. Preferably choking coils D1, D2 are included in the D.C. circuits.

Breathing apparatus comprises a casing divided into first and second chambers 9, 10 by a diaphragm 8, the first chamber 9 communicating with the medium surrounding the casing and the second chamber 10 communicating with a mouthpiece, valve means 28, 29 controllable by the diaphragm to regulate gas flow from a reservoir through the second chamber to the mouthpiece, first injector means for assisting flow of gas from the valve means to the mouthpiece and second injector means for assisting flow from the reservoir through the valve. The demand valve 28, 29 is opened or closed in response to movements of the diaphragm 8, the valve being operated by a pivotal arm 46 the free end of which extends outside the valve housing 23, 24 and into the chamber 10, a bent lever 43, 44 pivotal in a bushing 42 fixed on the valve housing transmitting movement of the diaphragm to the free end of the arm. One part 43 of the bent lever bears against the diaphragm, the other part 44 pressing against an adjustable screw 49 in the free end of the arm so that the loading of the diaphragm is adjustable. When pressure in the chamber 10 is below that in the chamber 9, the diaphragm operates the lever and arm to move the valve member 28 from its seat 29 into a sleeve 32 against a spring 33. The sleeve is closed at one end and surrounded by passages 35 which are filled with metal wool and connect the reservoir with the valve. When gas flows through the valve, a suction effect on gas within the sleeve urges the valve member further into the sleeve thus creating an injector effect and increasing opening of the valve. Gas flowing through the valve passes into a pipe 40 which extends through the chamber 10 and terminates in a pipe 13 leading to the mouthpiece. Flow of gas from the pipe 40 creates an injector effect on gas in the chamber 10.
