Abstract: 516,645. Gas producers. ADLER, R. July 4, 1938. Nos. 19715, and 19716. Convention dates, July 2, 1937, and Oct. 7, 1937. [Class 55(i)] [Also in Group III] The throughput of coal in a producer and also the supply of air and steam thereto are increased above the normal operating rates to obtain a residue of slag and ash mixed with 25-50 per cent. of carbon by weight, the coal being only partially gasified while maintaining the gas production. The residue forms an adsorption and purifying agent, particularly for bleaching and deodorizing liquids. In an example, a daily input of 25,000 Kg. of Bohemian brown coal consuming 5,000 Kg. steam with sufficient air to give a steam saturation of 45-50 per cent. is increased to an input of 27,400 Kg. of coal consuming 5,500 Kg. of steam, the steam saturation of the air being as before; the yield of slag and ash residue increasing from 1,000 Kg. containing 0 to' 3 per cent. of carbon to 2,500 Kg. containing 40-50 per cent. carbon. The adsorptive power of the residue may be increased by treatment at 650 to 900‹C. with steam in the absence of air, preferably in a muffle or retort furnace. The ground residue may be graded by means of sieves of different mesh.

Abstract: 985,549. Phase discriminators. RANK-BUSH MURPHY Ltd. May 24, 1961 [June 3, 1960], No. 19799/60. Heading H3A. In a television receiver flywheel sync. circuit the phase discriminator comprises a capacitor and rectifier C4, M3 and a rectifier and capacitor M4, C3 series connected in the order stated, a continuous sawtooth wave with steep flyback step as control waveform being applied with opposite polarities from a centre-tapped transformer winding 4 to the circuits C4, M3, and M4, C3 respectively, and sync. pulses from a sync. separator 7 applied between the junction of M3, C3 and R3 and the centre tap of input winding 4. A phase control output is then derived from the centre tap of a resistance R6, R4 connected across M3, C3, and smoothed by network R7, C9. The sawtooth waves are produced by integrating circuits R1, C1 and R2, C2 from pulses induced in winding 4 from scan transformer 1. The winding 4 may be an existing coil transformer coupled with a winding 5 in series with the line scan coil 2 and linearity control circuit 3 for automatic line amplitude control by keeping the total inductance in the line scan valve anode circuit constant, the existing winding 4 being doubled to provide the centre tap and adapt a television receiver for flywheel sync. by plugging in a printed discriminator circuit. In a modification, the junction of M3, C3 and R3 is earthed and sync. pulses applied to the centre tap of winding 4. Alternatively, C4 and M4 may be connected through a centre-tapped transformer across a small resistance in series with and receiving sawtooth current from a scan coil 2.

Title: Method and apparatus for fractionating gaseous mixtures
IPC: B01D53/047
Filed: 1958-06-20
Abstract: Gases are separated by passing under pressure through an absorbent which selectively removes one or more components, and before saturation is approached, de-sorbing with a part of the primary effluent flowing in the opposite direction to flow of gases in the absorbent stage and at a lower pressure to regenerate the absorbent. The process may be applied to drying gases, removing CO2, separating gaseous mixtures including hydrocarbons, chlorinated hydrocarbons and alcohols, and to separating a concentrated N or O/air mixture.  The absorbents used include active carbon, silica gel, alumina, molecular sieves, glass wool, absorbent cotton, or mobil beads.  A suitable apparatus consists of two absorber vessels 1, 2, Fig. 1, filled with an absorbent or layers of absorbent with separator plates, the inlet and discharge of which are connected <PICT:0850443/III/1> together through valved manifolds 9, 10, 18, 22.  A pressurised air stream at about 40 lbs. per sq. in. containing water vapour is admitted through an inlet 11, and passes through a check valve 9b, and 3-way flow switching valve 14 to an absorber 2, and the flow of effluent gas passing out through a pipe 12 is controlled by valves 21a, 23 to about 1 c. ft. per min.  A portion of the effluent gas passes via check 22a through the previously charged absorber 1 downwardly, the effluent and absorbed gas being discharged through a pipe 17 free from the absorbed component. The valves 13, 14 may be actuated automatically in controlled sequence, by solenoids 19, 20, to give an absorption cycle of 10 to 20 seconds, and a similar period for desorption.  The apparatus may be used to prepare a nitrogen-rich concentrate from air using as absorbent a molecular sieve material of 4 Angstrom.  The product as primary effluent contained 3 to 4% oxygen, the rest being nitrogen.  Graphs are given relating flow rate with oxygen content of primary effluent.  In a modified apparatus, a series of pairs of absorbers are used, in which primary effluents are produced, one rich in oxygen and the other rich in nitrogen. Preferably water vapour, and CO2 are removed in a pre-treatment stage consisting of similar absorbers charged with alumina.  For the nitrogen and oxygen concentrating absorbers, 4 Angstrom molecular sieve material is used to absorb oxygen, and either 5 or 13 A. to absorb nitrogen.  The effluents from each absorber stage may be cross-cycled with the other to then become an initial feed. Reference is also made to separating low molecular hydrocarbons e.g. from a mixture of ethane, ethylene, and propylene using molecular sieve materials.

In a method of photo-printing in which a predetermined density range is desired in the copies, although the originals have varying density ranges, a calibration curve 8 is first prepared for the particular copying material by making a series of test exposures in pairs upon the copying material each pair of exposures comprising one yellow light exposure and one blue light exposure in different colour proportions using a neutral density wedge as original to be printed, plotting for each exposure a density curve of print densities against the corresponding original densities of the neutral density wedge, determining from each curve the density range of an original corresponding to the desired predetermined density range of copies, and then interpolating the calibration curve by plotting the so determined original density ranges against the printing light colour proportions of the corresponding test exposures. This curve is then used to read off the proportions of the two colours of the printing light corresponding to the maximum and minimum density values and/or the density range of the original to be printed. In apparatus 1 for controlling the exposure of a photographic printer, an electronic timer is provided, the timer having one setting member 5 for setting the total exposure time and a second setting member 4 for setting the ratio of partial exposures in light of different colours; the member 5 is coupled to a scale 6 of density values movable with reference to a fixed index and the member 4 is coupled to a movable scale bearing the curve 8 and co-operating with the scale 6, the arrangement being such that the maximum density value of the original to be printed as indicated on the scale 6 is set against the fixed index, and the member 4 is adjusted so that the curve 8 cuts the scale 6 at the value corresponding to the minimum density of the original. A plurality of inter-changeable density scales are provided for use with copying materials having different Schwarzschild exponents.

Abstract: 614,077. Inductances. PHILIPS LAMPS, Ltd. July 4, 1946, No. 20012. Convention date, July 16, 1942. [Class 38 (ii)] An inductance 2 with a slidable core 3 has a number of turns 4 into which the core does not move, one or more of which turns may be unwound to alter the ratio between the maximum and minimum values of the inductance. If turns 4 are sufficiently spaced from the main winding 3 for the inductance ratio to change by at least 0.3 per cent on unwinding one turn, the adjustability is usually adequate for the desired ratio to be obtained despite manufacturing tolerances. Such an inductance facilitates the ganging of several tuning circuits.
