Title: Improvements in or relating to polishing machines
Inventor: BEECH ERNEST EDWARD
IPC: B24B57/00
Filed: 1956-10-03
Abstract: 825,294. Polishing. WALL Ltd., H. Aug. 19,1957 [Oct. 3, 1956], No. 30202 /56. Class 60. Apparatus for the application of a polishing composition to the surface of a polishing disc comprises a reciprocating carriage 1, Fig. 1, adapted to hold an elongated cake of polishing composition and to bring one end of it into contact with the disc at the end of each stroke, and an intermittent feed device for advancing the cake towards the disc relative to the carriage by a variable amount, comprising a pair of rollers which grip the cake. The cake of polishing composition (not shown) is held in the reciprocating carriage 1 between rollers 2 and 3. The roller 2 is carried by a spring-loaded cover 4 hinged at 5 to the carriage 1, whilst the roller 3 is mounted on the carriage 1 and driven intermittently, by the reciprocation of the carriage, through gearing actuated by a ratchet-wheel 17 ; a pawl 19 engaging the ratchet-wheel 17 is carried by a bell-crank to which is connected a lost-motion rod 23. The roller 2 may also be driven or, as shown, freely rotatable. An electric motor 12 drives an eccentric 10 through reduction gearing in the casing 11, bearing faces 9, 91 attached to the carriage transmitting the reciprocating motion thereto, but the carriage 1 may be reciprocated by electrical, hydraulic or pneumatic means. The upward motion of the carriage causes the angled portion 23<SP>1</SP> of the lost-motion rod 23 to slide, together with a block 24 to which it is attached, in a slot 241 in the fixed part of the apparatus, until such movement of the block 24 is prevented by an adjustable stop 25 held by a clamping screw 26. Further upward motion of the carriage 1 causes the rod 23 to move the bell-crank 21, 22 clockwise and thus to advance the cake of polishing material from the carriage towards the polishing disc. After the predetermined amount of angular movement has been imparted to the ratchet-wheel 17 the latter is held by a pawl 26<SP>1</SP> whilst the bellcrank 21, 22 and pawl 19 are caused to move anti-clockwise during part of the down stroke of the carriage. The motor is adapted to be switched off automatically when the polishing cake is almost wholly consumed by providing a pivoted member 27, Fig. 4, which is normally depressed by the cake to pull a spring-urged rod 28 downward and, as the end of the cake is fed past the member 27, releases the rod 28 to open a motor control switch. The Provisional Specification describes apparatus for the intermittent distribution of a flowable composition to the polishing disc incorporating a plunger which forces the compound through an orifice, or, alternatively, rollers may be actuated intermittently to squeeze the compound from a collapsible container.

Abstract: 534,762. Washing machines ; coupling shafts. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 17, 1939, No. 30251. Convention date, Nov. 17, 1938. [Class 138 (ii)] [Also in Group XXIV] Relates to a washing-machine of the kind in which an agitator is oscillated by a shaft which extends through a tubular vertical post, the agitator being connected at will to the oscillating shaft by a clutch operated by a cap that covers the upper end of the agitator hub. The upper end of the agitator 13, Fig. 2, terminates in a hub 14 which is rotatably mounted on a driving head 15 pinned to the oscillating shaft 11 and supported by a thrust washer 18 resting on the upper end of the tubular post 8. The agitator is slidable on the head 15 and may be lifted off the shaft for cleaning. According to the invention, clutch keys 21, Figs. 2 and 4, slidable in radial slots 20 in the head 15, have pointed teeth 22 on their outer ends that are adapted to engage in grooves or serrations 23 m the hub 14. The keys are held in their inner position, shown in Fig. 4, by a resilient split ring 24, and are thrust outwards, to lock the agitator hub to the head 15, when a plunger 31 having a pointed lower end 44 is forced downwards between their inner ends. The upper end of the plunger is screwed to a cap 32 that covers the agitator hub, so that downward or upward movement of the cap locks the agitator to, or releases it from. the shaft 11. The plunger is held in the agitator by a plate 38 that has its edges spun into a groove 40 in the hub. A snap ring 45, carried in a groove 46 in the teeth 47 between the serrations 23, engages notches 26 in the clutch keys and prevents the agitator from moving off the shaft 11.

Title: Improvements in or relating to apparatus for the purification of gases
Inventor: HARTLEY WILFRED
IPC: C10K1/22
Filed: 1953-11-02
Abstract: 746,788. Purifying gas. HUMPHREYS & GLASGOW, Ltd. Oct. 22, 1954 [Nov. 2, 1953], No. 30277/53. Class 55(2). In gas purifying apparatus of the type wherein the gas pas. ses through a down wardly-moving pack. ed bed of iron oxide which is removed at the bottom and re. plenished with re. vivified oxide at the top, the revivified oxide is fed through a shoot rotatable about the axis of the purifier, the discharge end of the shoot being of fish-tail profile sc as to extend across substantially the whole width of the bed. As shown, the shoot 10 has a cylindrical upper part 11 co-axial with the container 12, and is supported by a circular plate 16 resting on rollers 17. The shoot is rotated, so as to sweep across and correctly form the upper surface of the oxide bed, by a pawl mechanism (not shown) which engages ratchet teeth on the periphery of the plate 16. The upper part of the shoot is located by rollers 9 which bear against rings 20 on the shoot. The outlet from the shoot is a narrow slot and cut-outs may be provided in the trailing edges of the bottom of the shoot to facilitate feeding out of the oxide as the shoot is rotated. The ends of the shoot are cut away to provide side outlets 15 through which oxide is discharged to build up against the walls of the container. The bottom 14 of the shoot, moreover, is of convex profile to produce a concave upper surface of the oxide bed, which compensates for the reduced density of the packing of the oxide near the walls due to the frictional support offered by the walls to the oxide. The depth of the oxide bed may be controlled by fixing adjustable extension plates to the lower edge of the shoot. The upper part of the shoot, and the container, may be of non-circular cross section.

Abstract: 427,650. Valve circuits for wireless reception. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London.-(Assignees of Travis, C. ; 354, West Allen's Lane, Philadelphia, U.S.A.) Nov. 3, 1933, No. 30587. Convention date, Nov. 5, 1932. [Class 40 (v)] In a system in which automatic gain control is applied to an amplifier, the signal is rectified and the D.C. component of the voltage produced is amplified and applied to effect the gain control through a second rectifier which is biassed to delay the application of the control potentials until the signal reaches a predetermined amplitude. As shown, the detector diode 19, 16 of the double-diode triode valve 9 has a load resistance R1, the D.C. component of the voltage developed across which controls the bias of the amplifier triode portion of the valve 9 in which an adjustable amount of the audio frequency component is amplified. The anode load resistance R4 is connected between the cathode 16 and earth, amplified audio frequencies being fed to a succeeding amplifier through a condenser 25. The grids of the controlled valves 1, 6 are connected through the lead 23 to the diode anode 20 whose circuit includes the resistance R4 and the section lying below the adjustable point Y on a potential divider P connected between earth and the high-tension supply. The cathodes of valves 1, 6 are connected to a tapping 22 lying above the point Y so that the grids are initially biassed negatively owing to the difference of potential between the points 22, Y. When no signal is being received the potential drop in the resistance R4 is greater than that between the point Y and earth so that the anode 20 is negatively biassed and no A.V.C. voltages appear in the lead 23. When the signals exceed a predetermined amplitude, the potential drop in resistance R4 is diminished to such a point that the anode 20 is positive and A.V.C. potentials reach the lead 23. The diode 16, 20 is shunted for audio frequencies by a condenser C3. In a modification, Fig. 2, (not shown), the output load of the valve 9 for audio-frequencies is a transformer feeding a subsequent amplifier, while in a further modification, Fig. 3, (not shown), the amplifier is arranged to feed a push-pull amplifier. Reference has been directed by the Comptroller to Specification 407,317.
