Title: Control valve mechanism
IPC: B60T15/04
Filed: 1944-10-19
Abstract: 593,077. Multiple - way valves. JOHNSON, E. D. Oct. 19, 1944, No. 20261. [Class 135] A valve mechanism, particularly for controlling the How of pressure fluid to two fluidpressure-actuated devices, e.g. vehicle brakes used for steering purposes, and permitting either selective or simultaneous operation of these devices by a single control lever 55, comprises two sets of inlet and exhaust valves 31, 48 and 41, 52, operable by the lever. Conduits 7, 8, connecting with the devices communicate, through passages 22, 24 respectively, with chambers 20, 21, the supply of pressure fluid to which is controlled by the inlet valves 31, 41. When the lever 55 is in its neutral position shown, the exhaust valves 48, 52 are held open by stems 59, 58, engaging cam surfaces 64, 63 on the lever, thereby, venting the pressureactuated devices to atmosphere through ports 47, 51. For selective operation, the lever 55 is rocked about a pin 57 to open one of the inlet valves and permit the corresponding exhaust valve to close, whilst opening further the exhaust valve of the other set. For simultaneous operation, the lever 55 is rocked about, the axis of a shaft 56, mounted for rotation in the valve casing, when, owing to the inclinations of the cam surfaces 63, 64, both exhaust valves 48, 52 are closed and both inlet valves 31, 41 are opened. Pistons 35, 45, interposed, with lost-motion between the inlet valves and the lever 55, produce " feel "for the operator. A latch 65, Fig. 4, is provided, for locking the lever in the position with both inlet valves open.

Title: Improvements in or relating to arrangements for modulating electric carrier wave oscillations
IPC: H03C1/58
Filed: 1951-08-28
Abstract: 699,539. Modulating systems. GENERAL ELECTRIC CO., Ltd., and HARLING, D. W. Aug. 14, 1952 [Aug. 28, 1951], No. 20274/51. Class 40 (v). A modulating system of the rectifier bridge type, particularly intended for use with television signals, comprises a cathode follower stage 2 fed on its grid with a modulating signal 1 and with its output taken across a cathode resistor 6 so as to apply the signals to the vertical diagonal 12, 26 of the rectifier bridge together with a D.C. voltage determined by the variable tap from the grid resistor 7 to the cathode resistor 4. The horizontal diagonal 17, 18 of the bridge is fed from the carrier source 19 through a transformer 20. Output is taken either across a resistor 22 shunting the vertical diagonal, or across a resistor connected in series with the bridge between the corner 26 and earth. The rectifiers are connected so that like poles of one kind are presented to the terminal 17 by the adjacent rectifiers, and like poles of the other kind to the terminal 18. The output across the resistor 22 comprises both side-bands together with pure carrier at an amplitude determined by the D.C. voltage across the resistor 6, which is dependent on the position of the grid tap on the resistor 4. The output is taken to the transmitter 24 through a capacity 23 and an amplifier and filter 21, which may be designed to pass the carriers and one side-band, but only a vestigial portion of the other side-band. The direct current level of the signal voltages applied to the grid of the valve 2 is clamped to a datum level by a diode valve 8. In a modified circuit, Fig. 2 (not shown), the tap on resistor 4 is replaced by a fixed connection, and the predetermined D.C. voltage is created across a resistor connected between the terminal 26 and earth. This resistor is connected in the cathode lead of a second valve similar to the valve 2 but with its grid earthed and its cathode current predetermined by adjustment of a second resistor in its cathode lead.

Title: Improvements in or relating to the manufacture of viscose
IPC: D01F2/08
Filed: 1922-07-27
Abstract: In the manufacture of viscose the treatment with carbon disulphide is effected in or in the presence of benzol or other organic diluent or solvent capable of dissolving or mixing with carbon disulphide; the temperature, during this stage of the process, is reduced by cooling for example to 0-5 DEG C; and the solvent or diluent may be allowed to remain during the ripening stage of the process.  Usually water will not be introduced in substantial quantity, the cellulose being treated with caustic alkali solution the surplus of which is extracted, and the treated cellulose being then introduced into benzol, &c. for the xanthogenation.  The benzol, &c. may be recovered by distillation in vacuo, or by the addition of water, and decanting. The process may be applied to the manufacture of high molecular viscose as described in Specification 183,882, according to which cellulose is treated with reduced amounts of caustic alkali and with the theoretical quantities of carbon disulphide.  Products such as artificial silk, prepared from viscose made according to the process, are distinguished by their greater strength.  Benzol or other diluent or solvent may be added during the preparation of the alkali cellulose, agents capable of chemically binding water being added in order to obtain a much more concentrated application of alkali so that the latter is more intimately seated on the cellulose; suitable agents are alkali or alkali earth metals, or their oxides or hydrides, or sodamide or sodium ethylate; the compound formed may itself serve wholly or in part as the alkali.  In examples of this modification, cellulose is treated with 50 per cent caustic soda solution, the surplus solution removed, and the mass then kneaded in benzol with calcium oxide: cellulose impregnated with a little water is mixed with sodium oxide in the presence of benzol &c.
