Title: Improvements in by-product condensers and methods of operating same
IPC: C10K1/04
Filed: 1921-01-10
Abstract: 157,828. American Coke & Chemical Co., (Assignees of Roberts, A.). April 17, 1915, [Convention date]. Condensing and washing plant and processes; washers.-A predetermined temperature is maintained in separate units of a coal gas condenser by spraying liquid under automatic control into each unit. The condenser comprises a number of columnar units 8 built up from sections 9 extending between a lower inlet manifold 11 and an upper delivery manifold 10. The gases enter at one end 16, and in passing upwardly through the columns are sprayed by an oil or emulsion which in evaporating reduces the temperature to the point desired, thereby determining the constituent brought down in the particular unit. The condensates may be withdrawn through openings 32 into seal pots 33 and thence into a reservoir. The delivery of gas through each column is separately controlled by valves 24 operated by hand wheels 25. A common oil manifold 38 has depending pipes 29 carrying nozzles 30. Each column has openings at its upper and lower ends for a thermometer. A temperature-actuated device for controlling the supply of oil is shown in Fig. 2. A volatile liquid in the vessel 40<g> responding rapidly to changes of temperature within the column operates a pressure valve controlling the supply of compressed air to a diaphragm valve 40<e> operating the oil supply valve. The incoming gas manifold and the columns may be jacketed. Within each section 9 are brackets 49 upon which rest removable racks carrying pivoted baffle plates 51; or the baffles may be triangular in cross-section or be staggered horizontal plates.

Abstract: 576,558. Eddy-current brakes. HEENAN & FROUDE, Ltd., and HAYES, C. T. Feb. 10, 1942, No. 1725. [Class 103 (i)] [Also in Group XXXV] The exciting coil of an eddy-current clutch, brake, or dynamometer, is supplied from a constant speed generator which is excited by' an exciter mounted on, or driven by, the movable element of the eddy-current apparatus, the excitation of which thus varies with the speed of the movable member according to a desired law. The exciting coil 11 is supplied by generator 3, run at constant speed by three-phase motor 2. The field coil 7 of generator 3 is supplied, through control resistances 9, 10, by an exciter 12 running on the same shaft as a moving element of the eddy-current apparatus. The exciter 12 has a shunt winding 13 and a winding 14 separately excited by a small generator 4 running with generator 3. Generator 4 also supplies reverse winding 5 which removes effects of residual magnetism in generator 3. To run up to speed, the switch 16 enables generator 3 to be shunt excited at the same time the winding 5 is reversed by switch 17, to prevent the generator reversing its polarity. To stop, winding 7 may be disconnected, or motor 2 may be switched off.

Title: Process for Production of Magnesium Hydroxide and Calcium Chloride
Inventor: STOWE ROBERT ALLEN
IPC: C01F5/22
Filed: 1967-01-13
Abstract: 1,178,162. Magnesium hydroxide and oxide; calcium chloride. DOW CHEMICAL CO. 13 Jan., 1967, No. 1843/67. Heading C1A. Mg(OH)2 and CaCl2 are produced by dryslaking calcined limestone and/or dolomite, introducing it into a precipitator in the form of a slurry dispersed in part of the precipitator effluent, mixing it with MgCl2 brine such that there is an excess of Ca(OH)2 relative to Mg salts in the precipitator, and separating the precipitated Mg(OH)2 from the CaCl2 solution. Calcination may be effected in a rotary kiln at 1150-1450‹ C. on material crushed to size ¢-2¢ ins. Slaking may be effected by spraying the calcine with 0À4-1À5 g. H2O per g. CaO, e.g. at 100‹ C. in a revolving cylinder with a residence time of 2-60 mins., sufficient to hydrate CaO but not MgO, and to remove excess water as steam. The precipitator may be operated at 50-60‹ C. under constant agitation and with a residence time of 2-24 hrs. The excess of Ca(OH)2 may provide a soluble alkalinity (ml. of 0À1NHCl required to neutralize 100 ml.) of 4-30. The brine may also contain CaCl2 and some NaCl, and up to 90 p.p.m. boron, and the effluent preferably contains at least 15 wt. per cent CaCl2. The Mg(OH)2 may be degritted in a cyclone, filtered and ignited in a rotary kiln to form dense periclase. The CaCl2 solution may be concentrated and sprayed on to tumbling CaCl2 particles.

Title: Improvements relating to television apparatus
IPC: H04N5/278
Filed: 1947-01-21
Abstract: 633,424. Television. CLAYDEN, R. T., and GIBSON, W. R. Jan. 21, 1947, No. 1848. [Class 40 (iii)] In a television transmitting system marking signals, the timing of which may be varied, are generated independently of the picture signals and caused to modulate the picture signal carrier so that at a receiver the marking signals produce a visible indication in a desired position in the reproduced picture. In the illustrated embodiment the marking signals are generated by means of pulse generators 6, 7, which, respectively, generate pulses at line and frame frequency under the control of the line and frame scanning generators 2, 3. The pulses produced in the generators 6 and 7, the firing time of each generator being controlled by potentiometers 8, 9, have a duration of the order of picture elements and picture lines respectively and are combined in a mixing device 11 and modulated on to the picture signal carrier in the transmitter 1. In the reproduced picture the line frequency marking pulses cause a vertical trace to appear and the frame frequency marking pulses a horizontal trace so that by operation of potentiometers 8, 9 the two traces can be caused to intersect at a feature of interest, the marking traces being black or white, depending on the relative phases of the marking signals and the picture signals. To produce a spot instead of an intersecting line indication the device 11 is arranged to supply an output pulse only when one of the line frequency marking pulses occurs simultaneously with a frame frequency marking pulse. In an alternative arrangement the device 11 may comprise a further pulse generator supplying a train of pulses such as to produce an indication of predetermined form, e.g. lines, spots, squares or circles. The means for operating potentiometers 89, which control the timing of the generators 67, may comprise a control handle in the form of a joy-stick mechanically linked to each slider arm. In a modification, the pulse timing means may comprise a device having a surface on which the picture to be transmitted is projected and which supplies potentials proportional to the co-ordinates of a point thereon selected by the operator, e.g. a device of the kind described in Specification 588,043.
Patent GB-755108-A (GB)
Title: Improvements in or relating to synchronising pulse separator circuits particularly for television
Inventor: COPE JOHN EDWARD
IPC: H04N5/08
Filed: 1954-01-21
Abstract: 755,108. Television. PYE, Ltd. Dec. 30, 1954 [Jan. 21, 1954], No. 1862/54. Class 40 (3). In a circuit arrangement for separating line and frame synchronizing pulses from the picture components of a composite television signal the latter signal is supplied to the cascade arrangement of two limiting devices each of which effects a limiting action on both the " tips " and " bases " of the synchronizing pulses. As shown in Fig. 1, the composite signal with positively-going synchronizing pulses is supplied at A to the input circuit of a first limiter valve V1 which operates with a low anode voltage and removes most of the picture components at the base and most of the noise components at the tips of the synchronizing pulses. The partially limited signal is developed across resistor R4 which forms the A.C. load for valve V1 and the value of which is chosen such that substantial grid limiting occurs in valve V2. V2 is therefore driven heavily into grid current and removes the remainder of the picture components whilst noise on the tips of the synchronizing pulses is removed by anode current cut-off of V2. The signal output from the anode of V2 may be differentiated by means of C3 and R9 and the differentiated waveform obtained at terminal C employed in automatic frequency control circuits for flywheel synchronization. Separation of the frame from the line synchronizing pulses is effected by supplying the output from either terminals D 1 or D2 to conventional pulse separation circuit. The output from D1 may be employed when using a non-linear integrator circuit of the type described in Specification 620,478 (but connected to operate on signals of positive polarity) and that from either D1 or D2 connected to the circuit shown in Fig. 3 when frame pulses of negative polarity are required.

Title: A process for the production of non-hygroscopic choline salts
Filed: 1952-01-24
Abstract: The invention comprises mixed polybasic acid salts of choline and calcium or magnesium.  They are made by treating salts of choline and polybasic acids still containing hydrogen atoms which are replaceable by metal with calcium or magnesium oxides or hydroxides, water-soluble calcium or magnesium salts, or difficultly water-soluble or water-insoluble salts of calcium or magnesium with acids which are weaker than the acid contained in the acid choline salt and thereby converting them into the corresponding calcium- or magnesium-choline mixed salts.  The acid choline salts may be converted into their sodium salts before treatment with calcium or magnesium compounds.  The products are non-hygroscopic.  Choline salts specified are the mono- or di-citrates and phosphates, mono-tartrate and maleinate and acid salts of butane tetracarboxylic acid.  Calcium and magnesium compounds specified are the oxides, hydroxides, carbonates, bicarbonates and chlorides.  Reactions may be effected in water or lower alcohols, the choline salt and calcium or magnesium compound being taken in equimolar quantities.  The products may be precipitated from solution by the addition of organic solvents.  In an example mono-choline citrate is treated in water with calcium hydroxide, the mixed salt being obtained on evaporation of the solution.
