Title: Apparatus for measuring the acidity of gases
IPC: G01N27/00
Filed: 1936-01-17
Abstract: <PICT:0448234/III/1> The acidity of sulphuric acid plant exit gases and the like is determined by contacting the gas with a standard oxidizing and absorbing solution such as hydrogen peroxide and then testing the latter, e.g. by the electric conductivity method.  The solution and the gas are contacted first in an oxidizing chamber and then in an absorption chamber so arranged that the same portions of gas and liquid are in contact with each other in each case.  The gas pressure and the head of solution are also maintained constant. As shown, solution from the reservoir 1 flows under constant head 2--3 into the oxidizing chamber 6, then through constant-head device 11 into absorption chamber 12, and finally through constanthead device 20 into the conductivity cell 26.  The gas enters at 8 and is drawn in turn through the oxidation and absorption chambers by the siphon 24 at a rate indicated by flow gauge 21, a drying-vessel 19 being provided to prevent condensation in the flow gauge.  The conductivity cell is connected to a recording ohmmeter (not shown).  At regular intervals a standard resistance may be momentarily inserted in the circuit in place of the cell to provide a calibration point on the chart.

Patent GB-452209-A (GB)
Title: Improvements in or relating to electrical remote control circuit arrangements
IPC: H03G1/02
Filed: 1935-01-18
Abstract: 452,209. Distant - control systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London, and OLIVER, E. C., Merj Kesfa, Baddow Road, Chelmsford. Jan. 18, 1935, No. 1807. [Class 40 (i)] In a system for the remote control of wireless apparatus, step-by-step switches C, R at the controlling and controlled stations move to the same position by a reciprocal control in which C takes one step automatically and sends an impulse to advance R one step, whereupon R takes a further step automatically and returns an impulse to advance C a further step, the cycle being repeated until C reaches a position marked by a selecting key K1-12. An indicating lamp SPL then lights and a control key CK is operated to send a reverse impulse to effect the desired control. One form of control consists in the completion of circuits to allow telegraphy from the controlling station. The operation of a selecting key, in addition to marking a terminal of wiper C3, connects up start relay ST. Relay EC energizes and connects up magnet DMC, which at its interrupting springs releases EC, and the latter in turn releases DMC. The switch C thus advances one step, and SP pulls up and prevents re-operation of EC. The operation and release of EC sends an impulse over the two-wire line to the controlled station where it is repeated by polarized relay N to magnet DMR to advance the switch R one step. Relay CK energizes, whereupon ER operates and releases in the same manner as EC to advance the switch R a second step and to send back an impulse to the controlling station, the relapse of the CK then preventing reoperation of EC. The impulse is repeated by AC to magnet DMC to advance the switch C a second step, whereupon SP falls back. The cycle is repeated until relay PL energized over wiper C3, locks and lights lamp SPL. Upon operation of the control key CK, relay CL extinguishes lamp SPL while relay RV applies current of reversed polarity to the line to operate polarized relay PR which connects up an actuating relay such as E, F over wiper R4 in series with SL. The actuating relay locks, and as soon as the key CK is released, SZ pulls up and homes the switch R. A pair of relays A, B connected to early terminals of wiper R4 are employed for telegraphy over the line. To telegraph from the controlling station, for example, the operation of A is brought about by means of a selecting key and the control key, whereupon telegraph signals from wire TK are repeated by RV over the line to PR, which repeats them through A to wire T. Telephony may be superimposed when key TPK is operated.

Filed: 1937-01-25
Abstract: 489,543. Optical sound-recording apparatus. GROVES, W. W. (I. G. Farbenindustrie Akt.-Ges.) Jan. 25, 1937, No. 2165. [Class 40 (ii)] [Also in Groups XXXVI and XL] A moving iron oscillograph comprises a permanent magnet for polarizing an oscillatory device which consists of two adjacent parts situated opposite the respective poles of an electromagnet so as to oscillate in opposite directions and such that the magnetic circuit for the variable flux is completed through the oscillatory device. In one embodiment, the permanent magnet 1 has polepieces 2, 3, Figs. 1 and 2, and the electromagnet core 7 is fixed to the pole 3 with its two pole faces adjacent magnetic reeds 8 secured between the magnet 1 and its polepiece 2. The two reeds are moved oppositely by the controlling currents in the electromagnet winding 5, 6, and carry a mirror 11 supported for example on knife edges 9 on the reeds and having further knife edges 10 bearing in recesses in the polepiece 2. For high frequencies the mirror is connected to the reeds through an elastic member. A block 4 and shim 13 serve to adjust the distance between the polepieces 2, 3. An adjustable bridge 15 serves to adjust the resonant frequency of the reeds and a damping member 16 serves to restrict the amplitude of vibration. To reduce the change in the reluctance of the polarizing magnetic circuit during vibration, the polarizing flux enters the edges of the reeds 8 from the polepiece 2 as shown in Fig. 6 and Fig. 7 (not shown) and the air gap between the polepiece 2 and the reeds is made greater than that between pole faces 7 and the reeds. In another embodiment, Figs. 8 to 10 (not shown), the polepiece 2 is disposed beneath the reeds 8 and an additional counter support for the mirror provided. In another embodiment, for producing photographic sound records, the mirror is dispensed with, the reeds 8, Fig. 11, being formed with integral serrated diaphragms 20 which control a beam of light 21, Fig. 13a, to produce a push-pull sound track. In the normal position of the diaphragms, as shown the lower apices of the serrations lie in the centre line of the beam 21, but if the sound track is to be reproduced by reversal development the beam 21 must be displaced so that the upper apices of the serrations lie on the centre line of the beam 21. The usual multi-hump variable width sound track may, alternatively, be obtained by arranging the serrations 20 of the two reeds to interpenetrate as shown in Fig. 14.
