Patent GB-614456-A (GB)
Title: Improvements in and relating to the oxidation of aliphatic olefinic hydrocarbons
IPC: C07C409/04
Filed: 1946-06-28
Abstract: Aliphatic mono-olefines other than ethylene are treated in the liquid phase at -50 DEG  to 150 DEG  C. and at atmospheric, raised or reduced pressure with oxygen or a gas containing oxygen in the absence of a catalyst, but under the influence of ultra-violet light. Under these conditions an olefine CnH2n yields an unsaturated hydroperoxide CnH2n-1OOH as the main reaction product, but unsaturated aldehydes, ketones and acids may also be produced.  An example is given in which amylene (mainly trimethylethylene) is treated with oxygen at atmospheric temperature and pressure in an irradiated quartz tube to yield a product containing 3 - methyl - 2 - butenyl hydroperoxide (Me2C : CHCH2OOH) and 2-methyl-2-butenyl hydroperoxide (MeCH : CMeCH2OOH); these compounds yield unsaturated alcohols by reduction with sodium sulphite.  Other specified starting materials are propylene, n-butene-1, n-butene-2, isobutene, n-pentene-1, n-pentene-2, n-hexene-2, n-heptene-3 and mixtures of mono-olefines with one another or with other substances, e.g. paraffins.

Title: Improvements in and relating to electric testing instruments, more particularly for testing thermionic valves and measuring resistances
IPC: G01R31/25
Filed: 1933-07-13
Abstract: 420,762. Detecting faults ; current meters ; resistance measurements. ROOKE, F., Clyvdene, Bramstan Gardens, Bramley, Leeds. July 13, 1933, No. 19818. [Class 37] A portable apparatus for testing thermionic valves for emission, insulation resistance, and inter - electrode short circuits comprises a transformer A having a primary winding A<1> and two secondary windings A<2>, A<3>. The primary winding A<1> is tapped in order to operate on alternating current supplies of different voltages. The secondary winding A<2> is adapted to supply current at a low voltage to the heater or filament of the valve, and is connected to the heater terminals C', C<5> of a valve-holder C. Tappings are taken to a switch B to enable the voltage to be selected. The secondary winding A<3> is connected through a neon lamp F, moving iron milliammeter G, and variable resistance H to the arms D<1>, E<1> of switches D, E which are gauged together. The switch contacts are connected to the sockets c<1>, c<2>, c<3>, c', c<6>, c' of the valve-holder C and to a socket c<8> for connection to a valve having an external connection in such a manner that the secondary winding A<3> can be connected between any two elements of the valve. Short-circuits are detected by a reading on the meter G and a glow in the lamp F. By tapping the valve an intermittent shortcircuit is indicated by flashes in the neon lamp. Emission is measured by the reading of the milliammeter G and causes a direct-current glow in the lamp F. By closing a switch V the reading of the milliammeter G may be adjusted to full-scale deflection by means of the resistance H. Resistances may then be tested by connection to sockets W, X. Resistances P, U, T may be connected between the anode and screen in certain types of valves by closing switches Q, R, S.

Filed: 1933-07-13
Abstract: 422,565. Converting. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London. - (Assignees of Palmer, H. L. ; Toll Street, Scotia, New York, U.S.A.) July 13, 1933, No. 19850. Convention date, July 13, 1932. [Class 38 (ii)] An electric powerconvertingarrangement comprises an arc discharge device 12 having a control grid and a control circuit for the grid including an inductance device 16, a resistor 13 and a transformer 14 supplied with current from the A.C. source 11 so the grid potential is in phase opposition to the anode. The presence of the reactance device, however, by its inductive effect delays the instant at which the grid periodically becomes negative until the anode becomes positive, thereby rendering the discharge device conductive. In response to any predetermined condition, switch means 18 closes its contacts 19 to short circuit the secondary winding of the reactive device 16 and changes the phase of the grid control to bring the grid and anode potentials into exact phase opposition and render the discharge device non-conductive. When the load 10 is inductive, a negative bias is applied to the grid circuit by means of a capacitor 23 and leak 24. In a modification, (not shown), the inductance reactive device is replaced by a capacitance and resistance in parallel, the switch device interrupting the resistance circuit and introducing the capacitance to neutralize the inductance in the grid circuit.

Filed: 1945-08-03
Abstract: <PICT:0596886/III/1> In apparatus for detecting the presence of explosive gases in air or other inert gases, of the kind in which the gas passes through a detecting chamber and an indication is given in accordance with the combustibility of the mixture, the sampling line is provided with an adjustable dilution valve H by means of which inert gas may be mixed with the gas under test, and a scale J or its equivalent indicates the degree of dilution at each setting of the valve.

Abstract: 1458909 Colour television tubes; electron multipliers MULLARD Ltd 4 April 1975 [7 May 1974] 20019/74 Heading H1D A colour TV display tube comprises channel plate I, a gun producing a scanning beam, a colour luminescent screen with phosphor regions P 1 , P 2 , P 3  and a colour-selection electrode system located on, and insulated from the output face of the channel plate, and which comprises two commoned sets of interdigitated selector strip electrodes ES1, ES2. The tube uses lower energy electrons, lower switching voltages and eliminates colour impurities due to non- normal electron emergence (e.g. in 110 degree tubes). The electrode system may be on but insulated from the output electrode of a continuous dynode type plate, or a focusing electrode Mf as in Specification 1,458,910 (Fig. 4, not shown). Cyclical potential differences switch beam bo between strip P 2  and stripes P 1  and P 3 . Electrode Ea may be on the side of the phosphors remote from the support W. Layer Dn may be etched back from the channel exit to reduce charge deposition, may be replaced by dielectric stripes, or may be a pattern of dots or islands on which the strip electrodes are supported, while strips ES1, ES2 may extend partly into the gaps between channels. The phosphors may be dots and electrodes ES1, ES2 need not have straight edges (Figs. 3, not shown). In Fig. 4 (not shown), the dynodes and selector electrode strips are of re-entrant aperture form. Dimension (d7) of electrodes (ES1, (ES2) may be greater than (d5) to reduce unwanted secondary emission. A second focusing grid of the same form and dimensions as a dynode may be included at the position of electrodes ES1, ES2, the latter being replaced by thinner strips insulated from the output face. The spherical form of channels is not essential. Potentials and dimensions are given. Fabrication may be as in Specification 1,434,503, and a continuous type plate may be reduced lead oxide glass. In a flat tube (Fig. 7, not shown), electrodes d(b) provide the horizontal scan of the beam from the offset gun and horizontal strips d(a) provide the vertical scan. Line sequential operation may be used, the system as in Specification 1,331,938 preventing line crawl or colour creep. Alignment problems are avoided by line scanning at right angles to the stripes, line sequential operation avoiding synchronism problems of Indexing type tubes. Colour tube deflection angles may be 130 degrees or more. References are included to several other Specifications 1,458,910 claims a channel plate with focusing electrode provided on but insulated from the input face, the apertures of the focusing electrode having input cross-sectional areas less than the cross-sectional areas of the channel output ends.
