Title: A process for the removal of a component from a gas mixture
IPC: B04C3/02
Filed: 1960-11-29
Abstract: A process for the removal of a component from a gas mixture, e.g. H2S, CO2, SO2, HCN or NO from mixtures containing them, comprises entraining particles of a reactant as defined below in a stream of the gas mixture, passing the gas stream with the particles entrained therein through a reaction zone, in which the forward movement of the gas stream at any point is in a direction substantially parallel to the wall or walls delineating the reaction zone at that point, and subsequently removing particulate material from the gas.  The reactant is defined as a substance which will remove a component from a gas mixture by reacting chemically with it or by chemical or physical absorption.  Several removal stages may be used, each for removing a different component, or a mixture of reactants may be used to remove two or more components simultaneously.  Reactants mentioned are iron oxides for removing H2S, NO, and HCN; CaO for removing CO2; MgO for removing CO2 and SO2; and alkalies, e.g. NaOH, for <PICT:0941618/C3/1> removing H2S, SO2 and CO2.  Referring to the drawing, a two-stage process is illustrated in which H2S is removed from a gas mixture, in which gas mixture from the first stage is passed into pipe 4 which is the reaction zone of the second stage. Fresh reactant particles together with a quantity of circulating reactant material (Fe2O3, Fe(OH)3, or NaOH) are fed into this gas stream at 1 from a bin 2 via a cellular wheel 3.  The gas stream containing entrained reactant material passes through reaction zone 4 and into cyclone 5 where the gas mixture passes off through pipe 6. Part of the separated reactant material returns to bin 2 while part is taken off via cellular wheel 8 to bin 9 in which is reactant for the first stage.  The first stage works similarly to the second stage except that part of the reactant material separated in cyclone 13 is drawn off via wheel 15 into a rotary kiln 16 where it is regenerated and returned to bin 2 for the second stage.  The gas leaving cyclone 13 passes to the second stage.

Abstract: 947,619. Aircraft feel simulators. H. M. HOBSON Ltd. Nov. 2, 1962 [Nov. 24, 1961], No. 42187/61. Heading B7G. A feel simulator in an aircraft having a tailplane adjustable to trim the aircraft, imposes on the control column an hydraulic pressure P which varies with the tailplane displacement D, the rate of increase of P with D suddenly becoming smaller at a value of D determined by q, the difference between the total and static pressures, the change-over value of D decreasing as q increases. The Figure shows a housing 15 divided into chambers 24, 25, by a diaphragm 26 connected by a flexible seal 27 to a valve rod 28. The chambers 24, 25 are connected to sources of static and total pressure respectively. The pressure P is maintained in a conduit 16 connected to a jack operating on the control column in known manner, Fig. 2 (not shown). A valve 31 is connected to rod 28 through a relief valve 32 and the rod is subject to springs 33, 34 and 39, the compression of the latter being increased with D by a cam 41 on a shaft 40 rotated with tailplane displacement. The diaphragm is subjected to springs 37, 38, the compression of the latter being decreased as D increases by cams 42 on shaft 40. When q is low, the diaphragm abuts a stop 44A on the housing, and the load on rod 28 is varied only by cam 41 through spring 39. Variation in the load displaces valve 31 to connect conduit 16 to a pressure line 43 or exhaust line 44, until the pressure P beneath valve 31 recentres the valve, so that P is maintained proportional to D. As D increases, the compression of spring 38 decreases, and at a value of D, which value depends on q, the diaphragm lifts off stop 44A, and abuts stop 45 on the valve rod. As D increases further, the load on the valve rod is varied by cams 41 and 42 through springs 39 and 38, the compression of spring 38 decreasing as that of spring 39 increases, to give a nett rate of increase of P with D which is lower than that when spring 39 alone is effective.

Title: Voice-frequency signal receiver with speech-immunity circuit
IPC: H04Q1/46
Filed: 1962-11-09
Abstract: 1,019,532. Speech immunity circuits. STANDARD TELEPHONES & CABLES Ltd. Nov. 9, 1962 [Nov. 16, 1961], No. 42442/62. Heading H4R.  In a voice frequency signal receiver provided with a speech immunity circuit, a non-selective pre-amplifier feeds a series resonant circuit, comprising the mutual inductance of two windings of a transformer and a capacitor, which separates the signal frequency from the speech frequencies, the two being rectified and applied in opposition to a Schmitt-trigger circuit. The pre-amplifier comprises transistors Tr1 Tr2 provided with an amplitude limiter circuit C1, D1, D2. The output is fed through transformer T1 to transformer T2 which has identical windings I, II tuned by capacitor C2 to the signal frequency. This signal is developed across winding III and is rectified by D3, D4 and applied to resistor RS. All other frequencies are developed across winding II and C2, and are rectified by bridge D5, D6, D7, D8 and applied to resistor RG. Amplifying transistor Tr5 has RS and RG connected in series in its base circuit. The Schmitt-trigger circuit comprises Tr3 and Tr4, and with no input signal to the pre-amplifier Tr5 is cut off, holding Tr3 on, and Tr4 cut off, so that the voltage at A is nearly - 36 volts. For input signals comprising speech frequencies, or mixtures of speech and signal frequencies, the base of Tr5 is maintained at a positive potential and thus the receiver is blocked. When the input comprises only the signal frequency, the voltage developed across RS is amplified by Tr5 and cuts off Tr3 which allows Tr4 to conduct so that the potential at A is nearly zero. A plurality of tuned circuits with their associated Schmitt-trigger circuits may be connected across the secondary of the transformer T1. 1. AGC may be used in the preamplifier instead of the limiter circuit.
