Title: Improvements in or relating to thermionic valve circuits
IPC: H04N5/067
Filed: 1938-04-25
Abstract: 514,065. Signal combining circuits. BLUMLEIN, A. D. April 25, 1938, No. 12343. [Class 40 (iv)] [Also in Group XL] A thermionic circuit for. mixing electrical signals or generating pulses comprises two or more valves with a common cathode impedance. In the mixing circuit the signals are applied to the valve grids and the output taken from one or more of the anode circuits since a signal applied to one valve produces potential va,riations across the common cathode impedance. 'The output is limited by arranging that when the positive value of the signal exceeds the desired value the potential of the cathode is such that the amplification of the other valves is reduced or eliminated. Fig. 2 shows a pair of valves 11,12 with a common cathode resistance 13 used for generating pulses. A source of controlling pulses having sharp leading edges is applied to a valve 20 having a delay network 18 in the cathode circuit. The valves 11, 12 being connected to tappings the separation of which is such as to give the required length of pulse. The input may be saw-tooth waves for line scanning in television and the valves 11, 12 may be biased to cut-off and so arranged that the signal changes the current flow from one valve to the other. The valves may be neutralized by cross coupling which tends to sharpen the waveform of the pulse output. Specification 482,740, [Group XL], is referred to.

Abstract: 1,198,844. Periodic brakes. B. & F. CARTER & CO. Ltd. 15 March, 1968 [16 March, 1967], No. 12426/67. Heading F2E. [Also in Division D1] The rotor(s) of a wire twisting machine is controlled so that the rotor(s) may be brought to rest in any selected one of a limited number of angular positions in each of which one or more bobbins on the rotor(s) is in a loading or unloading position. The control of the rotor(s) is effected by selectively rendering operative any one of a series of cam-actuated switches 16, each of which is associated with one of a series of angularly spaced cams 11 mounted on rotor. The rotor is permitted to rotate until the cam associated with the selected switch actuates the selected switch to (a) cut off the drive to the rotor and apply a braking torque sufficient to ensure that the rotor comes to rest in a required loading or unloading position or, alternatively as shown, (b) reduce the drive speed to the rotor and using one cam 10 of a second series of angularly spaced cams all associated with a further cam-actuated switch 15 to cut off the drive and apply the braking torque. The rotor may be braked by a solenoid controlled air valve acting on pneumatically operated rotor brakes. As shown, a master switch may slow the rotor down to 7 r.p.m. before the cam 11 actuates switch 16. The cams 10, 11 are mounted on one of a set of spindles 9, the brake cam 10 being fixed at one end and the retarding cam 11 being positioned at any one of six positions along the spindle so as to actuate one of the switches 16. The switches 15, 16 are supported on a plate mounted parallel to the rotor axis. This switch plate is pivoted into and out of the switch operative position, wherein the switches are in line with the cams, by a pneumatic ram. The operative position for the switch plate is regulated by an adjustable stop (20). The switches 16 are in series with respective control switches so that they are effective only when the control switch is also closed. The cams which actuate the rotor retarding switches 16 may be shaped so as to maintain them closed whilst the rotor moves through 30 degrees, the brake cam 10 then acting at midway between the ends of the retarding cams 11. Upon release of the cam-actuated switches the rotor may be permitted to rotate, e.g. by operation of the restart switch, until it can be brought to rest in the position in which the next bobbin in the frame(s) is in the loading or unloading position.

Title: The metal xanthates of the haloaryloxyalkanols
IPC: C07C329/00
Filed: 1952-05-21
Abstract: The invention comprises metal xanthates of haloaryloxyalkanols, particularly those of formula: <FORM:0710036/IV (b)/1> wherein n represents 2 or 3, X represents a metal and R represents a haloaryl radical.  Such compounds are prepared by reacting together a haloarylalkanol, a hydroxide of an alkali or alkaline-earth metal (including magnesium), e.g. sodium, calcium or potassium hydroxide, and carbon bisulphide.  Products in which X represents sodium or potassium may be reacted with an aqueous solution of an alkaline earth metal salt or heavy metal salt, e.g. barium acetate, zinc chloride, copper sulphate or aluminium acetate, to produce the corresponding metal xanthate.  Reaction temperatures of 20 DEG  to 40 DEG  C. are suitable.  In examples (1) and (2) potassium 2-(2,4-dichlorophenoxy) ethyl xanthate is produced by adding potassium hydroxide to a solution of 2-(2,4-dichlorophenoxy) ethanol and carbon bisulphide in diethyl ether and normal pentane respectively, the reactants being in approximately equimolecular amounts.  Similarly prepared are (3) potassium 1-(4-chlorophenoxy)-2 - propyl - xanthate; (4) potassium 1 - (4-chloro - 2 - methyl - phenoxy) - 2 - propyl xanthate; (5) potassium 1-(2,4,5-trichlorophenoxy)-2-propyl xanthate; (6) sodium 2-(2,4-dichlorophenoxy) ethyl xanthate; (7) sodium 2 - (2,4,5 - trichlorophenoxy) ethyl xanthate.  There are also listed additional compounds of the above general formula, where R-O- represents a 4-choro-2-methylphenoxy-, 2,4-dibromophenoxy-, 2,4,5-trichlorophenoxy-, pentachlorophenoxy-, 2 - chlorophenoxy-, or 2 - bromo - 4 - chlorophenoxy radical, n is 2 or 3 and X is sodium, potassium or calcium.  Zinc 1-(4-chlorophenoxy)-2-propyl xanthate is prepared by reacting potassium 1 - (4 - chlorophenoxy) - 2 - propyl xanthate with zinc chloride.  The haloaryloxyalkanols used as starting materials may be prepared by reacting an alkali metal salt of the appropriate phenol with a monohaloaliphatic alcohol such as ethylene chlorhydrin, propylene chlorhydrin, 2 - chloro - 1 - propanol, 3 - bromo - 1 - propanol, 1 - chloro - 2 - propanol, 3 - chloro - 2 - butanol, and 3-chloro-2-pentanol.  A list is given of ethanols and propanols substituted by the halophenoxy radicals specified above.

Abstract: 545,779. Signalling through wave guides. LELAND STANFORD JUNIOR UNIVERSITY, BOARD OF TRUSTEES OF. Aug. 14, 1940, No. 13009. Convention date, Aug. 24, 1939. [Class 40 (v)] Signals are relayed substantially unidirectionally along a wave guide by selectively receiving the signals traversing the guide which are then amplified and directionally re-radiated for continued passage along the guide in the initial direction of travel. Fig. 3 shows a relay apparatus in which signals art. received by spaced dipoles 2, 21 the phase being adjusted by a concentric line 10 which is adjusted as to length. The amplifier is of the type described in Specification 530,785 the resonators 27, 28, 29 being tuned by means 44 as described in Specification 548,725..Amplitude adjustment is made by knob 111 controlling the loop 24 and the output is fed to spaced dipoles 5, 51 a concentric line 12 providing the appropriate phase adjustment. The output across anode load resistance 45 is utilized to control the bias of a grid 48 to serve as an automatic volume control. The antennae 2, 21 are preferably one quarter wavelength apart so that signals in the reverse direction balance out, or in the case of the transmitting antennae 5, 51 transmission is in one direction only. With two directional signalling little feedback obtains if the relaying stations for the two directions are equally spaced as the attenuation between stations as well as the directivitiy and spacing of the phased aerials restrict the feedback. Fig. 2 shows an amplifier relaying between guides 54, 62 in which adjustable apertured plates 56, 561 are used to match the line to amplifier impedance. Discrimination may be effected by frequency by means of a filter, Fig. 6 (not shown) as described in U.S.A.
