A shaft 10 for the periodic actuation of a chain conveyer for a typographical or paperworking machine is driven by a spur pinion 12 operated intermittently, e.g. in single-revolution steps, by a rack 14 which is alternately engaged with and disengaged from the pinion by the rotary movement of a support casing 32 about a pivot 36 effected by a control cam 44. The rack 14 is reciprocated between guides 18, 19 and reaction rollers 24, 25 on a frame 20 carried by casing 32 by means of a crank mechanism, which also operates a link 48 driving the cam 44. The rack 14 is effective during its up-stroke and near the end of its travel cam 44 is so positioned that a loading spring 40 can rotate the frame 20 and casing 32 clockwise to disengage the rack 14 from pinion 12 and cause a series of locking teeth 52 on casing 32 to engage pinion 12. The latter remains locked on the idle downstroke of rack 14, at the end of which cam 44 rotates casing 32 counterclockwise to disengage teeth 52 and re-engage rack 14 with pinion 12 preparatory to the next upstroke of the rack. The casing 32 carries an adjustable screw 42 which is engaged by cam 44.

A number of circumferentially extending grooves at the periphery of a drum cutter of a mineral-mining machine are each adapted to receive a laterally extending projection 5 of a bit holder 4 so that when the projections 5 are housed in the grooves the bit holders are prevented from being moved in the radial direction or from being tilted or turned while permitting the bit holder to be moved in the circumferential direction of the drum. In one embodiment inwardly directed lugs 5 on each bit holder 4 engage around T-section bars 2 secured to and projecting from the peripheral surface of the drum. In a second embodiment channels of T-shaped cross-section are formed in the peripheral portion of the drum, and in a third embodiment rectangular channels are cut in the peripheral portion of the drum and members fixed to the periphery of the drum to overhang the sides of the channel. The members are formed by fixing a band over the mouth of the channel and parting the band intermediate its edges. Portions of the bars 2 or channels are cut away to permit of the entry of the lateral projections of the bit holders into the recesses and these portions are closed after the entry of the bit holders by locking members which cause the bit holders to be pressed tightly together.

Abstract: 636,364. Gas and steam turbine plant. SOC. RATEAU, and ANXIONNAZ, R. Aug. 29, 1947, No. 23977. Convention date, Sept. 3, 1946. [Class 110(iii)] The exhaust from gas turbines T1, T2, Fig. 3, is used in a waste-heat boiler G to generate steam which is used in a'turbine Tcp and afterwards delivered to an external user by pipe E. To meet extra demands at the pipe E, the boiler is heated by a burner A controlled by a flow meter r3 in the steam pipe leading to the turbine Tcp. Alternatively, to meet extra demands for power from the gas turbine T2, the flow of exhaust gas through the boiler G and the flow of exhaust gas and air through the heat-exchanger R are regulated by circulating fans V3, V, and V2 under control by the flow meter r,. The pressure of the delivery to the pipe E is maintained by throttling the steam turbine inlet. The speed of the power unit is controlled by a speed-governor r2 which controls the fuel supply to the combustion and re-heat chambers Ch1, Ch2. The plant shown in Fig. 1 has no exhaust heat-exchanger. The fuel supply to the combustion chambers is regulated to maintain constant the pressure of the steam supplied to the turbine Tcp. Alternatively, the fuel supply of the combustion chamber Ch1 is so regulated and that of the chamber Ch2 is regulated to maintain constant the inlet or the outlet temperature of the turbine T2. Extra heat may be applied to the waste-heat boiler G.

The unit also includes an elongate member 102 adapted for attachment to valve 5. In use when the flexible wall 215 is depressed the opening 106 is first closed by the tapered end 117 of the member 102 engaging seat 107 and the valve 5 is then opened, gas or aerosol entering chamber 110 via aperture 116. Release of the wall 215 will effect closure of valve 5 and dispensing of the gas or aerosol via opening 106. The unit 100 may be adhesively or heat bonded to the container 1. The flexible end wall of the unit 100 of Fig. 1 may be replaced by a reciprocable piston member (Fig. 8 not shown). In a further modification the metering unit side wall is of concertina type and the end wall to which the mixing unit is to be connected is rigid (Fig. 9 not shown). The unit 100 may, as shown, be used in conjunction with a mixing unit 200, and in this case the container 1 will be charged with pressurized gas. The mixing unit 200 of plastics material e.g. polypropylene frictionally engaged or otherwise attached to the unit 100 e.g. by a bayonet joint, screw threads or a snap fitting arrangement, contains a granular material having a particle size of 10-100 microns. The unit 200 includes an outer body 201 provided with an outlet 205, and an inner body 204 frictionally fitted or bonded to the outer body and defining therewith a flow path for conducting pressurised gas dispensed from the unit 100 into the chamber 217 containing the granular material. The path comprises passages 209 and an annular passage 218. Prior to use the outlet 205 and the other end of the mixing unit 200 are sealed. An alternative form of mixing unit (Fig. 4) is attached to the outlet end of a modified metering unit 100 by means of a flanged locking ring 316 screw threadedly secured to the metering unit.
