Convention dates, Sept. 17, 1932, April 22, 1933, July 22, 1933, and July 22, 1933. [Class 53] A cell particularly for applying potential to the grid of a vacuum tube consists of two electrodes immersed in a glycol or glycerol, such as ethylene glycol or glycerine, or in a compound thereof such as the borate, to which is added a small amount of a weak organic acid such as lactic, malic or tartaric acid. The compound produced by heating boric acid with ethylene glycol or glycerine until dissolved may be used. One electrode may consist of aluminium, magnesium, beryllium, cadmium, zinc or an alloy or amalgam of one or more of these metals, or of chromium, silver or silver plated metals. The other electrode may consist of cuprous oxide, iron oxide, lead peroxide, vanadium pentoxide, cadmium oxide or of a sulphide or selenide of these metals, or of carbon or carbides such as those of nickel and iron. The Figure shows a number of cells in series having a tubular casing 1 of fibre or other material enclosing discs 2, 5 constituting the electrodes separated by plugs 4 of cotton, paper or cloth impregnated with one of the compounds enumerated above. The plugs 4 are enclosed in washers 3 of rubber, paraffined paper, &c. and lead discs 6 divide the tube into compartments and form the connections between the cells. Pressure is applied to all the cells by a spring 8 and the casing is closed by metal end caps 7. Different voltages may be taken from the device by means of tappings. The Specification as open to inspection under Sect. 91 states that the liquid in which the electrodes are immersed may consist of a polyhydric alcohol, benzol, acetone, gum arabic in water, tri-acetin or other organic substance which has no action on the electrodes. Glycerol formate made by heating glycerine and ammonium formate may be used, or the viscous liquid obtained by heating triethanolamine with oleic acid and ethyl ether of ethylene glycol.

Title: Improvements in or relating to electrical trigger circuits employing thermionic valves
Inventor: BEAUFOY RAYMOND
IPC: H03K3/12
Filed: 1954-09-02
Abstract: 801,681. Electric digital - data - storage apparatus. BRITISH TELECOMMUNICATIONS RESEARCH, Ltd. Aug. 31, 1955 [Sept. 2, 1954], No. 25527/54. Class 106 (1). [Also in Group XL (c)] Fig. 2 shows a bistable trigger circuit used in a magnetic storage system in which each of the two digits of a binary code is represented by two successive magnetized states the order in which these occur being reversed in the two cases. The information to be stored arrive at the input in the form of a signal as represented in Fig. 3, A, this waveform is mixed with strobe 1, waveform C, Fig. 3, and produce waveform B which is applied to input B. When the first digit 0 begins tube V1 is conducting and V2 cut off, the cathode voltages of these tubes are as shown in waveforms D and E, Fig. 3. The current through tube V1 causes a positive saturation of the magnetic material passing the recording head, this continuing until the time of strobe pulse 1. This pulse applied causes tube V2 to conduct and V1 to be cut off the cathode potentials change, as shown in waveforms D, E, Fig. 3, and the current flow in the secondary winding of transformer T1 causes a reverse, i.e. negative saturation of the magnetic material passing the recording head. This continues until strobe 2 pulse is applied the controlling potentials for which are supplied by the cathodes of tubes V1, V2. Since when strobe 2 is applied the cathode of tube V1 is at its lower level - 10 volts tube V1 is caused to conduct thus restoring the trigger to the state in which it was when the recording of the digit 0 began. Thus, as shown, in waveform G, Fig. 3, the digit is represented by an ordered pair of magnetized states, similarly digit 1 is represented by a first state of positive saturation and a second of negative. Rectifiers MR14 and MR15 prevent the anode potential from rising substantially beyond the power supply voltage and the resistor R15 and capacitor C5 cause the anode potential to be lowered to a value not higher than that of the power supply. Specification 801,682, [Group XL (c)], is referred to.

Title: Method and apparatus for the analysis by radiation of mixtures of gases and/or vapours
IPC: G01N21/37
Filed: 1957-08-16
Abstract: 849,983. Infra-red gas analysers. HARTMANN & BRAUN A.G. Aug. 16, 1957 [Aug. 18, 1956], No. 25912/57. Class 40(3). In an infra-red gas analyser, modulation of the radiation falling on a detector 13 is produced by periodic variation of the pressure of the gas in a sample chamber 3 through which the gas to be analysed is fed. As shown in Fig. 1, the pressure variation is produced by a piston 6 working in a cylinder 5 and the detector 13 is a diaphragm condenser. In a modification, the piston and cylinder are replaced by a chamber and a deflectable diaphragm, and a filter cell is arranged between the infra-red source 1 and the sample chamber and a non- selective detector such as a bolometer thermocouple or photo-cell is employed. In another modification, Fig. 5 (not shown) including a filter chamber and a diaphragm condenser, the sample is supplied to the sample chamber through a valved pipe and leaves the chamber through a pipe which is alternately opened and closed by a slotted or equivalent rotary disc. In a modification of this, the fluctuation of pressure in the sample chamber is effected by a diaphragm which is vibrated by using a slotted disc at the outlet of a chamber supplied with compressed air. In another modification, a rotary valve alternately connects the sample chamber with the sample supply and with the atmosphere. In another construction, Fig. 10 sample and reference gases are supplied to chambers 3h, 33h by pipes 9h, 380h and the outlet pipes 10h, 131h are closed alternately by a slotted rotary disc 26h. The output from the diaphragm condenser 13h is applied as a feedback to a control valve 38h to balance the absorption by the sample and reference chambers, the gas present in the sample being obtained from a pressure guage 39h. In another construction, Fig. 11, comprising a twin-beam instrument, a sample chamber 3m extends over both beams and is connected to a piston 6m and cylinder 5m. Non-selective detectors 19m, 191m are employed with filter chambers 21m, 211m containing the sample gas and a reference gas respectively. In a modification, the filter chambers are connected to chambers forming the two chambers of a diaphragm condenser. Reference has been directed by the Comptroller to Specification 749,689.

Classes 123(2) and 123(3) A stoker-fired water-tube steam boiler has two grates 12, 14 at the bottom of a furnace chamber which has a wide lower portion 62 with a cross-sectional area appropriate to the combined grate area and an upper narrowed portion 70 to each side of which are disposed gas downpasses 66, 102, the furnace chamber and downpasses being contained in a setting with upright walls and of rectangular cross-section. The front and rear walls of the furnace and downpasses are lined with upright steam generating tubes such as 42. The side walls of furnace portion 62 are lined with steam generating tubes 54, 56, some of which extend vertically lining the side walls of the downpasses 102, 66 and then are bent to line the respective downpass roofs 114, 92 and are connected to a steam and water drum 48. The other tubes 54, 56 are inwardly inclined and then have upright sections 104, 68 defining the side walls of the upper furnace portion 70 and forming partitions separating the upper furnace from the adjoining downpasses. Some of the tubes 104, 68 are inwardly and then upwardly directed to form screens 110, 112 and 76, 78 through which furnace gases flow into the downpasses, all the tubes being connected to the drum 48. Immediately behind the screens are disposed the vertical limbs of L-shaped secondary superheaters 108, 82, their respective horizontal limbs spanning the tops of the downpasses on each side. Beneath the superheater 108 the downpass 102 locates a primary superheater 176, 177 and an economizer section 162 whilst the downpass 66 contains further economizer sections 170, 171, 172 only. The downpass outlets are controlled by dampers so that a constant degree of superheat can be maintained over a wide load range by varying the gas flows through the downpasses. The narrowing of the furnace above the grate gives increased gas turbulence correcting the effect of concentration of combustion products adjacent the rear wall tubes 42.
