Title: Improvements in apparatus for the removal of solid particles from gases
Inventor: SWIFT PETER
IPC: B01D47/02
Filed: 1955-02-16
Abstract: 782,202. Washing gases. DALLOW, LAMBERT & CO., Ltd. Feb. 13, 1956 [Feb. 16, 1955], No. 4643/55. Class 55 (2). Solid particles are removed from gas by passing the gas over the surface of a liquid W, usually water, towards a space 7 defined by a baffle, or baffles, 6 arranged above the liquid, in such manner that water is entrained in the gas stream and passes upwardly through the space 7 into contact with a curved baffle 8 which produces turbulence and constrains the gas to flow laterally under the edges of the curved baffle and through the spray falling therefrom, the water flowing down the baffles 6 being, at least in part, entrained by the ascending gas-water stream and recirculated. The gas flow is produced by an exhaust fan 9, the gas being admitted at 3 into the space between an inner casing 4 and an outer casing 1. The gas is divided into two opposed streams which collide and change direction abruptly immediately below the space 7. This removes some particles from the gas, the remainder being removed in the region of turbulence below the baffle 8. The cleaned gas passes to the outlet 5 through an inclined spray eliminator 15 consisting of spaced plates which are shaped to define zigzag gas passages, the upper edges of the plates being downwardly lipped to collect residual droplets and, because of the general slope of the eliminator, to allow them to gravitate to one side of the casing 4 and, from thence, back to the sump 2. In a modification, a vertical partition is arranged in the middle of the space 7 to divide the opposed gas-water streams which then collide with the partition instead of with one another. The sloping baffles 6 are apertured at intervals at 14 to provide entrances to lutes 13 which lead water from the baffles 6 back to the sump 2. The lutes project beneath the surface of the water W, and the water level in the lutes is higher than the level in the sump to an extent dependent upon gas pressure differential above and below the baffles 6. The sides of the lutes may be extended upwardly from the baffles 6 to the baffle 8, in which case the turbulence of the gas escaping under the baffle 8 between the lutes is increased. The sludge in the sump 2 may be removed through doors, or through a bottom drain valve, or by a conveyer of the drag link type. Automatic means may be provided for maintaining the correct difference in water levels in the sump and in the lutes.

Title: Dynamic readout of pulse counters
Inventor: KREBS PETER ERIC
IPC: H03K21/08
Filed: 1970-01-30
Abstract: 1,263,876. Counter read-out. SOLARTRON ELECTRONIC GROUP Ltd. 31 Dec., 1970 [30 Jan., 1970], No. 4689/70. Headings G4A and G4H. When a decade counter 40 1 -40 p  is to be read out, an input 46 steps ring counter 45 to enable gate 47 1  and resets bi-stable 50 so that fast clock, pulses 44 are applied to all decades 40 through gates 41 and to a single decade counter 53 which is preset to 9. When units decade reaches a count of 9, gate 47 1  sets bi-stable 50 to close gate 55, so that counter 53 which is counted down by the clock pulses, now holds the count originally registered in decade 40 1 . To read out the next decade 40 2  a further input 46 is applied to step ring counter 45 to enable gate 47 2  and decades 40 and 53 are respectively counted up and down from the count registered at the end of the preceding decade read-out, until decade 40 2  reaches 9. The process is repeated for the following decades 40. The output of counter 53 may be decoded and applied in parallel to the cathodes of indicator tubes 58 which are switched on in synchronism with the decade read-out by the outputs 46 of ring counter 45.

Filed: 1933-02-16
Abstract: 415,079. Thermionic valves and circuits. KRAMOLIN, L. L. DE, 25, Nassauischestrasse, Wilmersdorf, Berlin. Feb. 16, 1933, No. 4804. Convention date, Feb. 17, 1932. [Classes 39 (i) and 40 (v).] An amplifier comprising two or more discharge paths arranged in series, i.e. with the anode of one connected to the cathode of the next, is characterized by the feature that capacity shunt-losses from the cathode of the second or succeeding stages are minimized. This result may be secured by using indirectly-heated cathodes ; or some of the cathodes may be of the photo-electric type ; or a tuned rejector circuit coupling may be used between the stages. One tube may be a diode operated at saturation to serve as an impedance-coupling to the next stage of amplification ; or it may be a triode or tetrode and take part in the process of amplification. Owing to its high A.C. impedance, the saturated diode also serves as an effective decoupler, and humeliminator. Fig. 3 shows an arrangement in which the triodes a, d, both connected in series, are coupled through a saturated diode d1 to the next and similar stage of amplification b, e, e1. The amplifier d may be back-coupled to the amplifier a (Fig. 2, not shown) ; or reaction may be added to the amplifier d alone (Fig. 8, not shown). Fig. 7 shows a series arrangement of two tetrode amplifiers a, d; whilst Fig. 10 shows a triode and diode combination a, d, directly coupled to a succeeding amplifier b, automatic grid bias being provided through a resistance 24. Further, to reduce capacity leakage, certain of the electrodes are used to screen one unit from the next. The indirectlyheated cathodes are of the "smooth" type, the surface being coated with metallic barium by a distillation process. Fig. 6 shows a multi-stage valve construction in which an amplifying triode system 9, 7, 10 is combined with a diode system formed of the outer bariumcoated surface of the anode 10 and an additional anode 13. In Fig. 9, the triode 7, 9, 10 is combined with a diode, consisting of a photoelectric cathode 11 and an anode 13. Fig. 11 shows an indirectly-heated triode 7, 9, 10, in series with a saturated diode 10, 13 directlycoupled to a directly-heated triode stage 25, 26, 27 ; an extension 28 serves to screen the lower assembly of electrodes from the upper. A series arrangement of two indirectly-heated triodes may also be mounted on the same bulb (Fig. 5, not shown). Specifications 316,306, [Class 40 (v)], and 402,431 are referred to.

Abstract: 662,733. Piles; consolidating earth. STEUERMAN, S. Feb. 20, 1948. [July 1, 1939] No. 5135/48. Classes 68 (i) and 68 (ii). [Also in Group V] A process for intimately mixing a loose mass of material and a liquid comprises simultaneously vibrating the material and directing into the mass a flow of the liquid. For "densifying" soil, a vibrator 38 and a conduit 37 are sunk to the required zone 40. Water is fed to the zone through the conduit 37 and enters the soil where the vibrator (of the eccentric weight type) is operating. The external pressure is provided by the difference in height of the water 35a in the conduit 37 and the natural water level 36. As the zone 40 is densified, the vibrator and conduit are raised and a higher zone 39 treated. To sink the vibrator into position, it is provided with a conduit 38b; water is supplied on the outside of the conduit to permeate, as at 79, into the soil and to supply the external pressure. Water is also supplied through nozzle 92 in the vibrator, and this stream densifies the soil, forming a funnel-like crater into which soil 73 is emptied, and also densified. Additional external pressure may be applied by means of weights 77 on the conduit 38b. In pile driving, the pile is made in situ by forcing cement paste through a further nozzle 93 in the vibrator, and dropping concrete aggregates into the crater instead of soil.

Abstract: 220,667. Dubilier, W. Feb. 23, 1923. Hiring telephones.-High-frequency signalling- currents are excluded from, or admitted to, the house conductors of a lighting, power, or telephone system, by means of enclosed blocking circuits which are magnetically coupled to the line, and may be put out of action by the insertion of a coin when the occupier desires to listen to the signal communication. The main conductors A shown in Fig. 1, divide into a number of branch circuits B, B<1>, B<2> and separate blocking circuits are shown for the main line and the several branches. A blocking circuit comprises inductance coils D in series in one or both lines, and one or more condensers C across the lines. When both lines are insulated from earth, the mid-point of the condensers C may be earthed. The coils D have only a few turns and are coupler to coils E of greater resistance and inductance forming part of circuits E, F tuned to the high frequency. The blocking device is enclosed in a locked or sealed casing H and may be controlled by switches arranged to short-circuit the coils D or to disconnect the condensers C. The switches are normally in position to render the blocking-device effective, and are shifted into position to pass the high-fre quency currents for a predetermined time by the insertion of a coin into the casing. When a number of carrier currents of different frequency are employed, separate blocking-devices tuned to the respective frequencies are arranged in. series. in the lines, each having separate control switches, operated by independent coin-freed mechanism. The various blocking-devices maybe arranged in compartments in a single-casing.
