Abstract: 903,353. Rotary filters. STAMICARBON N.V. Feb. 10, 1961 [Feb. 12, 1960], No. 5116/61. Class 46. A cylindrical filter drum 5, Fig. 1, is supported between rollers 7a (one of which is driven continuously or intermittently) and 7. Suspension is supplied at 11, 12, 13 and divided into two streams. Some of the liquid carries oversize material into a trough 14 (with optional assistance from a backwash spray, not shown, at the top), while remaining liquid and undersize, if any, are discharged at 3. The feeding device may be arranged at the top of the drum but in that case the drum must be provided with a conical rim at the forward end, (see 18, Fig. 6), for discharge of oversize and its attendant liquid, and either, the drum axis must be inclined towards the forward end, or a brushing or like device must be provided. Such a device is shown in Fig. 6. A long brush 19 is pivoted at each end to a disc (only 21, the right hand one, being shown), the discs being rotated counter-clockwise so that each point on the brush executes a circular movement in a vertical axial plane to sweep oversize from between the bars 6. One of the rollers 7a is driven intermittently by the brush drive mechanism through gearing. Preferably the screen bars are fine-gauge rectangular or wedge-section wires. Alternatively the drum may be formed of perforated plate. The apparatus may be used to carry out the method of Specification 791,520 or 791,857.

Title: Improvements in liquid dispensers
IPC: B67D7/70
Filed: 1922-02-22
Abstract: 199,427. Golby, F. W., (Bowser & Co., Inc., S. F.). Feb. 22, 1922. Actuating by foot power; rack-and-pinion actuated pumps; indicating action of; single-acting bucket pumps; suction reservoirs; valves, arrangement of.-Apparatus for dispensing liquids comprises a liquid reservoir 16 in which is mounted a pump cylinder 24 provided with an inlet valve 26 and a reciprocating bucket 33. The liquid displaced during the downstroke passes through the bucket rod 32 and a valved piston 34 carried by the rod and working in a transparent cylinder 28, from which the liquid is forced during the upstroke through a valved delivery pipe 101. The rod 32 is rigidly attached by means of a member 41 to a rack 38 gearing with a pinion 45, which is mounted in a sliding member 44 and is actuated by a rack 39 connected to a pedal 42. During the first downstroke of the pedal. the pinion is locked by a catch 49 pivoted on the slide 44, and the two racks and the pinion and rod 32 move down together, forcing the liquid from the cylinder 24 into the cylinder 28. At the end of the screw, a screw 63 on the member 41 engages a bracket 62 on a bar 60, which is pivoted at 61 to the levers 55, 56 pivoted on the frame on which the racks slide. These levers carry a bar 54 provided with a slot 53 in which slides the end 52 of a spring 51 controlling the catch 49. When the bar 60 is moved down by the screw 63, the levers move the bar 54 into the position shown in Fig. 6, thereby detaching the catch from the pinion and moving it into a notch in the frame 40, so that the pinion rotates during the upstroke of the rack 39 under the action of a spring. During this movement, the rack 38 and rod 32 do not move. On the next downstroke of the rack 39, the pinion rotates and raises the rack 38 and rod 32, so that the liquid is forced from the cylinder 28 into the delivery pipe. At the end of its upstroke, the rack 38 lifts a latch 70 from a bar 68, to which the lever 56 is pivoted, and allows a spring to move the bar 68 to the left, thereby returning the levers 55, 56 and bar 54 to the starting position shown in Fig. 4, in which the catch 49 engages the pinion. The movement of the bar 68 may operate the hammer 73 of a bell to indicate the completion of a delivery stroke. The catch 49 and bar 54 prevent the return of the rack 39 until the first downstroke has been completed, and the release of the dog 70 necessitates the completion of the second downstroke of the rack 39.

Title: Improvements in sound reproduction
IPC: G03B31/00
Filed: 1934-02-16
Abstract: 432,221. Scenic exhibitions. DOWDING, G. V., 215, Hainault Road, Leytonstone, London. Feb. 16, 1934, Nos. 5203 and 11859. [Class 132 (i)] [See also Groups XX, XXXIX, and XL] As air vibrations of a sub-audible frequency produce sensations of feeling or emotion on human beings, the dramatic or emotional sensations provided by visual scenes, e.g. in stage plays, or pictures produced by cinematography or television, or the realism of sound reproduction is enhanced by emissions of such vibrations under the control of means associated with scene producing or sound reproducing apparatus. As a continuous emission is liable to produce painful effects, it is arranged that the emission is intermittent or of varying amplitude or frequency. When accompanying sound reproduction, the sub-audible vibrations may be superposed on the sound and reproduced by the same loud-speaker, and their amplitude may be controlled in accordance with sound Volume. Mechanical or electrical air vibrators may also be used. In the arrangement shown in Fig. 1, a sound or picture film 5 has contacts 4 adapted to make connection between fixed contacts 6 to short circuit part of the bias resistance which normally paralyzes a valve oscillator 2 so that oscillations are supplied to a loud-speaker 1. Manual control 7 may be used in addition. When an electrical vibrator is used, its circuit may be closed by a relay operated over the contacts 4, 6. In modifications two sets of contact devices may be provided in order to change the tuning of the valve oscillator or to vary the amplitude of vibration or to select different vibrators. In the arrangement shown in Fig. 5 for controlling the subaudible vibrations in accordance with sound volume, the oscillator 19 tuned by a condenser bank 21 is connected over potentiometer 24 to the control grid of variable mu valve 25. Sound currents over circuit 29, 30 are rectified at 31 and the resultant voltage over resistance 32 is applied over a de-coupling network to the control grid of 25 in such a sense as to oppose the normal bias due to resistance 26 which gives small gain. The output of 25 is further amplified and applied to the sub-audible loud-speaker 37 or may be injected into the sound amplifier for reproduction by the normal loud-speaker.

Abstract: 763,629. Controlling vehicles. POWER JACKS, Ltd. May 2, 1955 [Feb. 23, 1954], No. 5234/54. Class 79(5). [Also in Groups XXIX and XXX] A hydraulic system comprises a pump 23 driven by an internal combustion engine, a single-acting jack 26 and a control valve A, the pump being continuously driven at idling speed by the engine. When the valve A is moved to the position for hydraulic actuation of the jack 26 the throttle of the engine is automatically opened. When idling the pump delivery passes to exhaust through a pipe 24. On operation of the valve A to the position in which the pump delivers to the jack pressure builds up and actuates a ram 29 connected to the throttle lever 30. In a modification, in order to control the speed of operation of the jack, the line to the ram 29 includes a restriction and a pressure release valve therefrom, the closure of which is progressively controllable with the movement of the valve A. In Figs. 1 and 3 (not shown) the valve A closes an electric contact so as to energize a solenoid actuating the throttle lever. The system may be provided for using the tailboard of a vehicle as a hoist for assisting loading and unloading, the tailboard being actuated by single-acting jacks which are returned by gravity.

Title: Shutter system for a motion picture camera
IPC: G03B9/10
Filed: 1974-02-05
Abstract: 1432727 Cinematographic shutters ELMO CO Ltd 5 Feb 1974 [6 Feb 1973] 05331/74 Heading G2E A shutter system for a cine camera comprises three sector blades driven in synchronism about a common axis, each adjacent pair of blades being coupled by a lost-motion device to permit limited relative angular displacement, the driving means comprising a motor connected to the first blade by a fixed gear train and to the third blade by a gear train including a cog capable of planetary motion about a second cog, the angular displacement between the blades being caused by a lever producing this planetary motion. The shutter drive is transmitted from a motor 14 through gear wheels 15 to 19'to a wheel 12 integral with the third blade 5 and through gear wheels 15, 16 to a wheel 13 connected to the boss 3. The transmission ratios are the same therefore wheels 12 and 13, and hence blades 1 and 5 are rotated at the same speed. When the shutter aperture is at a maximum, Fig. 1, blade 4 is driven due to a tab 8 thereon engaging a tab 6 on blade 1. To close the aperture e.g. for fade-out filming, a control lever 20, which is connected to the shafts of gear wheels 18, 19 by link work, is rotated about shaft 2 and moves wheels 18, 19, relative to wheels 12, 21 causing wheel 12 to rotate relative to wheel 13 without interrupting the gear train from motor 14. Blade 5 thus rotates clockwise relative to blades 1 and 4 until a tab 10 on blade 5 engages tab 9 on blade 4 causing blade 4 to rotate relative to blade 1 until finally tab 8 on blade 4 engages tab 7 on blade 1 when the shutter is fully closed. For fade-in filming the above process is simply reversed. In an alternative embodiment the blades entrain each other by pin and slot connections.
