In the embodiment described the lever 19 comprises one side of the pocket and the coin gauging member is a pin 23 carried by the lever. Alternatively the gauging member may comprise a lever pivoted on the pocket and connected to the lever 19. The other side of the pocket is comprised by a resilient plate 18 having a flange 22 normally closing an exit opening in another edge of the pocket. The pocket is rotatably mounted on a central spindle 12 of the quantity wheel 13 and, by means of a pocket front plate 7, on a shaft 9 of a handle 14, which is journalled in a fixed coin plate 2 and carries an injector plate 15. In operation the handle 14 is turned anticlockwise, an edge 15B of the injector plate co-operating with a drive tongue 27 carried by the lever 19 to rotate the, pocket 4 until a lug 40 on the front plate 7 engages a projection 41 on the back of the coin plate and coin slots 6 and 17 are aligned. A coin is then inserted and the handle 14 rotated clockwise, an edge 15A of the injector plate urging the coin into the pocket and pivoting lever 19 to bring striker 25 into engagement with the quantity wheel 13. On further rotation edge 15A engages a blocking surface of pawl 29 carried by front plate 7 to rotate the pocket and quantity wheel until a tongue 31 on flexible plate 18 engages a stop 32 to open the edge of the pocket and allow the coin to fall out. Pawl 29 presents a ramp surface to the edge 15B of the injector plate, preventing "pumping" of the meter mechanism. The, pre-paid quantity obtained may be changed by adjustment of the angular position of the coin plate 2 with the aid of notches 33 and fixed pin 34.

Filed: 1973-10-31
Abstract: 1440358 Percussive tools NIPPON PNEUMATIC MFG CO Ltd 31 Oct 1973 50720/73 Heading B4C A percussive tool comprises a hammer piston 12 movable upwardly by the pressure of liquid and downwardly to deliver blows to a tool 50 by gas compressed in the upper chamber of the cylinder 11, a limit valve 38 being provided which is actuated when the piston is raised to deliver the gas pressure of the upper chamber to a side valve 24 which lifts to cut off the liquid pressure source (20), Fig. 2 (not shown), and to open the lower chamber 16 and port 19 to the liquid outlet 23, 21. The gas, (e.g. nitrogen) is contained in a reservoir 31 which is replenished from a gas cylinder 42 and communicates with the upper chamber via the side valve chamber 29 and a duct 41 when the piston is in the lowered position shown. In this position the side valve 24 is pressed down on its seat 22 by the gas in the chamber 29 so that the liquid pressure from the source (20) can pass via grooves 26 and 27 to the port 19 of the lower chamber 16 to cause the piston to lift. When the piston covers ducts 40, 41, the gas trapped in the upper chamber is compressed and when the piston contacts the limit valve 38 to lift it off its seat, the compressed gas is communicated via a duct 46 to the side valve 24 in order to lift the valve off its seat 22 to open the lower chamber 16 to the liquid outlet 21 and shut-off the groove 27 from the liquid inlet groove 26. The piston 12 is then propelled down by the gas compressed in the upper chamber. When the duets 40 and 41 are again uncovered, the gas pressure is restored to normal and the side valve 24 is lowered. To damp abnormal liquid exhaust pressures, the side valve is provided with a slidable central member 32. If desired, the limit valve 38 may be lifted by gas pressure instead of by contact by the piston 12.

Abstract: 1419179 Dewatering dilute slurry WESTINGHOUSE ELECTRIC CORP 5 Nov 1973 [10 Nov 1972] 51205/73 Heading BID [Also in Division F4] Dilute slurry, e.g. from the final settling stage of a sewage treatment plant, is delivered to a reservoir 24 into which dips an endless moving belt 18 of absorbent material, which picks up some water therefrom before the slurry is conveyed by pump 34 to the upper run of a screen belt 20. Belt 18 absorbs more water from the underside of belt 20 and is squeezed to remove water by rollers 32 and 46. Water removed by roller 32 may be recycled to upstream of the plant, discharged or delivered to belt-washing nozzle 48. After filtering on the upper run of belt 20 the slurry cake is squeezed and lifted from the belt by roller 40 and scraper 44. Separate drive rollers 12, 14 enable a slight relative movement of belts 18, 20 to assist dewatering on the upper run, but rollers 12, 14 could be replaced by one roller. Belt 18 may be foamed polyurethane or fibrous synthetics (exemplified) and may be covered with mesh material, in which case belt 20 need not pass through reservoir 24 as shown. Figs. 2, 3 (not shown) illustrate the reservoir into which the belts are pressed and which contains rotary brushes 30 to prevent solids settling on the belts or reservoir floor. Belt 18 could be further squeezed in its upper run by passing through one or more sets of four rollers (not shown).

Abstract: 1,202,562. Cathode-ray tubes. EIDOPHOR A.G. 10 Nov., 1967 [16 Nov., 19661, No. 51357/67. Heading H1D [Also in Division H4] In a schlieren-optical system in which a modulated electron beam is scanned across a deformable light-modulating surface, the electrostatic charge deposited at each individual image point is confined to the area of the image point, and a secondary or neutralizing charge is deposited on the surface in the area surrounding each image point in order that images that are traced in single lines or that are built up of an arbitrary sequence of spots may be optically reproduced. The complete scanning cycle for forming the image is repeated at a constant repetition frequency and the surface deformation at each image point neutralized or at least substantially reduced during the interval between successive scans. The neutralizing charge travels at least substantially incidently with the image tracing charge which is preferably deposited intermittently. The neutralizing charge is necessary because the electrostatic pressure generated by the arbitrarily deflected electron beam would by itself cause the oil film modulation to disperse at the image points since the overall electrostatic surface charge produced when the oil film is raster scanned and which prevents the oil film from laterally yielding to the transient pressure when the individual image points in a line are traversed by the electron beam are absent. The neutralizing charge may be generated by defocusing the electron beam which also deposits the image forming charge. Preferably the neutralizing charge is generated by alternately underfocusing and overfocusing the image-forming beam. As described with reference to Fig. 3 (not shown) this alternating underfocusing and overfocusing may be effected by a trapezoidal voltage applied to a focus modulating system in the cathode-ray tube, the focus of the electron beam passing through the image plane at a speed determined by the steepness of the flank of the trapezoidal voltage. The magnitude of the neutralizing field and the charge density in the neutralizing field are varied by controlling the amplitude of the trapezoidal voltage. The frequency of the trapezoidal voltage is so chosen that it has no common submultiple with the image repetition frequency. Besides stabilizing the oil film against lateral spreading of the deformation at the image point, the neutralizing charge also assists in the smoothing out of the image point deformation by the surface tension of the oil film. If the image is formed by a plurality of differently positioned writing cycles, then the tracing and neutralizing electron beam is blanked out during the positioning cycles.
