Title: Improvements in and relating to filtering apparatus
IPC: B01D33/00
Filed: 1922-05-16
Abstract: 200,642. Oliver, E. L. May 16, 1922. Rotary filters.-The casing of a rotating-drum filter is provided with an oscillating agitator having, at either end of the filter, curved supports 76, 84, Fig. 8, which extend from pivots 86, 87, placed near the axis of the drum and above liquid level, to opposite sides of the agitator. The agitator is formed of curved end pieces 80 and longitudinal angle-bars 82. The arms 76 are continued beyond their pivots and connected by links 75 to cranks on the main driving shaft 69, from which the oscillatory motion is thus derived. The interior of the drum is divided into compartments connected by pipes 6 - - 12, and passages through one of the trunnions 4, Fig. 3, to a valve 33 at the end of the trunnion, by means of which each compartment is successively placed in communication with separate passages for the discharge of filtrate and wash-water under suction and with a source of gas under pressure, which aids the removal of the cake from the drum. The pipe 42, Fig. 2, connecting the valve 33 to the source of pressure is provided with a valve 45 which is opened intermittently, so that the cake is loosened just before each internal compartment comes opposite a scraper 47. The operation of the valve 45 is derived from cam timing-gear 31, the shaft of which rotates, for each rotation of the filter drum, a number of times equal to the number of the compartments of the drum. The perforated surface 18 of the drum is covered by several layers 19 of filter fabric, and wire 20 is wound round the otuside to prevent displacement of the fabric when pressure is applied within the drum.

Patent GB-731540-A (GB)
Title: Improvements relating to method of conducting chemical reactions and apparatus therefor
IPC: C01D7/18
Filed: 1950-06-03
Abstract: In a method of continuously conducting exothermic reactions between a solution of a reactant and a gas and involving a change of phase of the reaction product so formed from the dissolved to the crystalline state, of the type which comprises circulating in a closed cyclic path a body of supersaturated solution of the reaction product containing a slurry of such product, continuously feeding a reactant-containing liquid and subsequently in the cycle, a gaseous reactant and thereafter passing the mixture through cooled pipes at a velocity to create a turbulence equivalent to a calculated Reynolds number of 500 or more, and withdrawing a product slurry, the method is characterized by passing the body of supersaturated solution of the reaction product through the cooled pipes immediately after the addition of the gaseous reactant.  The method is exemplified in the Figure by the production of sodium bicarbonate from brine and ammonia and carbon dioxide.  A body of sodium chloride, ammonium chloride and sodium bicarbonate, saturated with and carrying a slurry of the latter is circulated in a cycle comprising a surge tank 5, a pump 6 <PICT:0731540/III/1> delivering liquid to a gas-injection stage 14, a cooled tubular reactor 7 and return pipe to tank 5.  Ammonia and carbon dioxide are fed from metering supplies 12 and 13 to the injection stage 14 whilst brine is fed from a tank 1 provided with an agitator through pump 3 to vessel 5.  A portion of the slurry is withdrawn by pipe 15 for recovery of the sodium bicarbonate produced. Production may also be effected in stages, two cycles above described being arranged in series.  In such a case all the brine and ammonia but only half the required carbon dioxide are added in the first stage.  A clear solution with no crystals results and is in part withdrawn for use as the liquid reactant in the second stage where the remainder of the carbon dioxide is injected.  The invention is also stated to be applicable to the production of ammonium sulphate by reacting a slurry of gypsum with ammonia and carbon dioxide and to the treatment of chromium ores with carbon dioxide to produce sodium dichromate and sodium carbonate.  The velocity of the circulating slurry through the tubular reaction zone should be held at a minimum consistent with reaction rate to avoid excessive crystal breakage but should always be sufficient to create the turbulence equivalent to the calculated Reynolds number of 500.

Title: A method of automatically cutting off the liquid supply to reservoirs and devices for effecting the same
IPC: F16K31/30
Filed: 1928-05-12
Abstract: 291,052. Muller, J. May 25, 1927, [Convention date]. Tanks.-A method of and apparatus for automatically cutting off the supply of liquid to reservoirs &c., such as the petrol reservoir 1, Fig. 1, as they become full comprises a filling tube 7 which is closed at its lower end and provided with lateral openings 10 over which slides a tubular valve 17 operated by a float 24. In use, a cover 11 with spring-pressed closure disc 13 secured by bayonet fitting 12 is removed and the tube 7 connected to the filling means. When the liquid reaches the predetermined height the float stem 23 abuts on the guide stem 19 of the valve and shuts off the supply. When the filling valve is disposed at the bottom of the reservoir the float operates through a cord, or for side filling through cords and levers. The float may be fixed to the valve, or it may have pins operating in inclined curved grooves in the valve to give a rotary movement. An easy movement is required between the valve and the tube and to ensure fluid-tightness at the completion of the filling, the openings ;nay be closed by a pair of discs or pump plungers forced over the openings by an interposed spring. An arrangement with a filling funnel is shown in Fig. 7 in which the funnel neck 55 terminates in a flange 56 and carries a sliding cap 58 which is secured by a bayonet fastening 59 on the filling tube 7 when the cover 11, Fig. 1, is removed. The flange 56 with interposed washer 60 is pressed by the enclosed spring fluid tight against the top of the tube 7. The neck of the funnel is normally closed by a manually operated valve 54. This funnel allows, as soon as filling is completed, of the removal of the excess of liquid remaining in the filling apparatus.

Title: Mechanism for counting the cigarettes delivered by a cigarette making machine
Inventor: COFFIN ERNEST VICTOR
IPC: A24C5/32
Filed: 1948-05-25
Abstract: 644,184. Counting-apparatus. IMPERIAL TOBACCO CO. (OF GREAT BRITAIN & IRELAND), Ltd. May 25, 1948, No. 14039. [Class 106 (i)] [Also in Group VI] A counter for the cigarettes delivered by a cigarette-making machine is driven from the machine through a clutch which is engaged only whilst cigarettes are issuing from the machine. In a machine wherein cigarettes cut from a continuous rod are transferred laterally from a travelling band 4 to a transverse band 5 by deflector vanes 3 on a continuously rotating shaft 1, the counter 20 is driven from the shaft 1 through chain and sprocket gearing 12, 16, 17 and a normally engaged clutch 23. Secured to the shaft 1 alongside the deflector vanes 3 is a block 13 to which is pivoted, adjacent each vane 3, a radially extending flap 15. As each cigarette arrives before a vane it abuts the flap and rocks it to a position such that, in the further rotation of the shaft, it passes to the right of a fixed curved guide 40 where it has no action on the clutch 23 so that the drive to the counter is maintained and the cigarette counted. If, at any time, no cigarette is received by a deflector vane 3, the corresponding flap 15 is not deflected and, in its further rotation from the lowermost position of Fig. 1, passes to the left of the guide 40 and between it and a pivoted guide 34 deflecting the guide 34 for a quarter of a revolution of the shaft 1 and, through an actuating arm 32, disengaging the clutch 23 against the action of a spring 24. The clutch is held disengaged by successive undeflected flaps 15 passing to the left of the guide 34 for as long as cigarettes fail to arrive before the deflector vanes 3 so that the drive to the counter 20 is interrupted. The machine shown has a second' set of deflector vanes 2 for forming a second row of cigarettes on the band 5, but the counting mechanism responds only to the cigarettes handled by the deflector 3.

Thermionic generators and ampliflers. - To prevent self-oscillation due to internal capacitycoupling in a multivalve amplifier used for shortwave transmission, the input and output circuits of successive amplifiers are tuned to different frequencies, these being derived from a local heterodyne oscillator. As shown a master oscillator 11 generates a frequency of 10,000 kilocycles. A local heterodyne 21 generates a frequency of 1,000 K.C., and is coupled to the input circuits of amplifiers 14, 15. The output of amplifier 14 is tuned to the difference or beat frequency of 9,000 K.C., which is then transferred to the input of amplifier 15 where it beats with the frequency of 1,000 K.C. from the oscillator 21. The output circuit 18 is tuned to the resultant difference frequency of 8,000 K.C. and this is fed to the transmitting circuit 13, with or without further amplification. Any known method of modulation may be used, such as the key 24 on the plate circuit of the amplifier 14.

Abstract: 698,678. Television receivers. GENERAL ELECTRIC CO., Ltd., and BRABHAM, H. B. S. June 7, 1951 [June 7, 1950], No. 14222/50. Class 40 (iii). In a television receiver employing a cathoderay tube, the picture signal, which may contain some distortion, is applied to one intensitymodulating electrode of the tube and a second signal, which contains the same general information as the picture signal and is derived therefrom, in a suitably modified form, is applied to another intensity-modulating electrode of the tube, whereby distortion originally present may be subjectively reduced in effect. In the arrangement illustrated in Fig. 1, whereby sharp edges which have been lost from the signal waveform due to the restricted bandwidth of the transmission waveform may effectively be restored to the signal applied to the cathode-ray tube, the picture signal applied to the cathode of the tube 5 is also applied with reduced amplitude and after integration by the network comprising potentiometer 6 and stray capacity 11 to the grid 8 of the tube 5. If desired, an actual capacitative component may be included in addition to the stray capacity. On account of the delay effectively introduced by the integrating circuit it may also be desirable to insert a delay network into the circuit to delay the signal applied to the cathode of the valve. In an alternative arrangement an integrating circuit is supplied from the cathode of a valve whose anode is coupled to the cathode of the cathode-ray tube. In a further arrangement, the second signal is derived by a circuit effecting double-differentiation. As a further alternative the two signals may be derived from separate receivers receiving the same radio transmission. In the arrangement shown in Fig. 7, the second signal is taken from the cathode circuit of the valve 42 whose anode load is such as to give the valve a voltage amplification factor of unity, thus compensating for the loss of gain at low frequencies.
