Abstract: 457,532. Valve circuits. MURPHY RADIO, Ltd., 62, Brook Street, Hanover Square, London, and DAVIES, K. S., and FREUNDLICH, H. F. W. J., c/o Murphy Radio, Ltd., Broadwater Road, Welwyn Garden Citv. June 7, 1935, No. 16603. [Classes 40 (iii) and 40 (v)] Signals of different amplitude are differentiated by a screen-grid valve 1 operating on the negative-resistance part of its anode volts-anode current characteristic. Television and synchronizing signals are applied to the controlling-grid, and grid bias, anode, and screen-grid voltage are applied from a potentiometer 3.. 6 such that the valve operates on the negative-resistance part of the characteristic for values of applied grid voltage between the maximum picture signal and the minimum synchronizing-signal. A resistance 2 in the anode circuit is approximately equal, numerically, to the apparent negative resistance of the valve, and the anode supplies a scanning circuit through a lead 14. The valve is shunted by a diode 7 or other unilateral conductor in series with a biassing potential (across the resistance 4), which is equal to the potential of the anode at the lower bend of its grid volts-anode current characteristic.

Abstract: 354,445. Skein holders or swifts. ROYSANCOUR, O. G. J. S. DE, Breda, Holland. May 29, 1930, No. 16675. Convention date, March 29. [Class 120 (ii).] A collapsable swift or reel for skeins or cakes of yarn, rayon, or the like comprises resilient arms which are substantially parallel to the axis of the reel and form an acute angle with the axis of the reel and with the free ends of the arms which constitute yarn carriers. The resilient arms 3 are fixed to a spindle 1 by means of a sleeve 2 which surrounds a preferably square tube in which the arms 3 are enclosed. The reel is collapsed to the position shown in dotted lines by means of a device 6, into the opening 7 of which the reel is pushed, deflections 4 being provided in the arm of the reel to prevent slipping. In the collapsed position the free edges of the yarn-carrying surfaces remain at a substantially constant distance from the axis of the reel while the other edge is brought much closer to the axis of the reel. The yarn-carrying surfaces 5 of the reel are either concave or may be corrugated to prevent shifting of the skeins on the reel. In a modified form the arms of the reel instead of being resilient in themselves are resiliently mounted for example in a holder of rubber.

Title: Method of detecting ionization current of gas discharged devices
IPC: G09G3/28
Filed: 1975-04-25
Abstract: 1505117 Testing ionization in gas discharge tubes; measuring current INTERNATIONAL BUSINESS MACHINES CORP 25 April 1975 [24 June 1974] 17155/75 Heading G1U A gas discharge device having electrodes insulated from the gas is tested by including it between first and second terminals of a bridge circuit also comprising two equal inductive arms between first and third terminals and a capacitor of the same value of capacitance as the unenergized device between the third and a fourth terminal with a power supply connected across the second and fourth terminals. The current through the inductive arms is sensed to indicate the ionization current. In the embodiment shown, Fig. 2 the inductive arms are the split primary windings W 1 , W 2  of a transformer, whose secondary winding W 3  provides the bridge output to an oscilloscope and peak detector. Since the components in the two bridge paths across the supply 20, 21 are equal, the bridge is balanced and when voltage pulses are applied to one or both supply inputs 20, 21 equal and opposite currents (I 1 , I 2 ) flow in the two paths resulting in a zero output from W 3 . When the supply voltage pulses are great enough, the gas discharge devices ignites providing an extra current pulse through one path only, resulting in an output from W 3  which is displayed and peak detected. The method may be used in testing display panels comprising discharge "cells" defined by the volumes between the intersections of orthogonal sets of conductors 10, 12 within a sealed envelope, the sets of conductors being on the bottom and top of the envelope respectively. Each row of conductors 12 has an associated current probe 4 comprising the device shown in Fig. 1. By suitable selection of the horizontal and vertical drive circuitry 14, 16, each cell can be tested for its ionization current. In a modification Fig. 4 (not shown) each probe 4 has a peak detector, each detector is followed by a differentiator, the outputs from which are combined in an OR-gate. By gradually increasing the supply pulse amplitude until a cell fires, the "maximum sustain voltage" can be found.

Title: Process for preparing halogen-containing unsaturated aliphatic nitro-compounds
IPC: C07C205/09
Filed: 1947-06-30
Abstract: Halogen-containing unsaturated aliphatic nitro-compounds are prepared by reacting olefinic halogen compounds, having the general formula <FORM:0637252/IV (b)/1> where R1, R2, R3 and R4 are hydrogen or alkyl groups, to react with aqueous nitrous acid or with nitrous gases, i.e. gases comprising nitrogen trioxide (N2O3) or mixtures of other nitrogen oxides, such as NO and NO2 which under the conditions employed react to yield nitrogen trioxide.  Generally, the olefinic halogen compound is treated with a dilute solution of mineral acid and an alkali nitrite, suitable acids being sulphuric, nitric or phosphoric acid; hydrogen halides are less suitable owing to possible formation of additive compounds with these acids.  Alternatively, the process may be effected by reacting the nitrous gases with the olefinic halogen compound dissolved in an organic solvent such as benzene. Reaction is normally carried out at room temperature but higher or lower temperatures may be used; continuous or batch-wise procedure may be followed at normal, raised or reduced pressures. The main products contain a primary nitro-group and are stated to be new; additive compounds with nitrous anhydride which are probably formed as intermediates may be present and may be decomposed by heat, preferably by mixing the crude product with an inert organic solvent or dispersing agent and heating at 80-110 DEG  C.  In the example, an aqueous solution of sodium nitrite is slowly added to a stirred mixture of methallyl chloride and 20 per cent aqueous sulphuric acid, the resulting oil layer removed, water-washed and heated with toluene to decompose additive compounds and then distilled first to remove solvent and then the desired 2-chloromethyl-3-nitro propene-1.  The latter is purified by dissolving in alkaline lye, extracting with ether, acidifying the purified alkaline solution and then again extracting with ether.  Methallyl bromide, 3-chloro-2-methyl butene - 1, 3 - chloro - 2 : 3 - dimethyl butene - 1 and 3 - chloro - 2 - methyl pentene-1 are other specified starting materials.  The products may be used to combat insects and other noxious organisms.
