Title: Improvements in or relating to the conversion of distillates obtained from coal, andthe like into products of lower boiling point
IPC: C10G15/00
Filed: 1930-09-11
Abstract: The proportion of oils of low boiling-point in distillates obtained by the destructive distillation of coal, lignite peat, and similar carbonaceous materials is increased by subjecting the whole distillate while still in the vapour phase and as it leaves the coal &c. retorts to a silent electric discharge. Hydrogenating gases such as hydrogen, methane, coal gas, or the gas remaining after the condensible constituents have been removed from the products produced by the reaction may be mixed with the vapours.  Vapours from coal retorts are passed through a chamber containing cylindrical metal electrodes connected with a source of current having a voltage of 8000 volts and a periodicity of 100. The distillates may be kept in the vapour phase by surrounding the chamber with a jacket through which hot flue gases are circulated. Voltages up to 100,000 with a periodicity up to 35000 may be used and under such conditions a product having a boiling-point about that of petrol is obtained. Specifications 104,330, 169,063, 275,120, 286,825, 288,270, and 318,270, [all in Class 32, Distilling &c.], are referred to.

Abstract: 1468044 Automatic phase control INTERNATIONAL STANDARD ELECTRIC CORP 20 June 1974 [28 June 1973] 27428/74 Headings H3A and H4A A signal receiving system in which a received input signal, e.g. at aerial AN 0 , is coupled to a receiver by a transmission means, e.g. a line Z 00 , includes a first phase locked loop APLC 00  comprising, a mixer M 02 , a phase detector PD 00 , a filter LF 00  and a voltage controlled oscillator VCO 00  which is coupled to one input of the mixer, the other input of which is coupled to receive a signal corresponding to the input signal and also includes signalgenerating means which applies to input K of the phase detector a modulated suppressed carrier reference signal, and which also supplies to a point CO 00  near to the circuit input a modulated suppressed carrier pilot signal whose carrier frequency is substantially the same as that of the input signal. The first phase locked loop APLC 00  removes from the received signal the phase shift introduced by the transmission line Z 00 , and a second loop FBL locks the phase of the received signal and that of the local reference signal. The pilot signal is transmitted from the signal generator to the point CO 00  near the aerial AN 0  by a further transmission line Z 01  whose phase shift is compensated for by an automatic control loop SLC 00  which includes a controllable delay LS 00 . This control is effected by transmitting down the line a signal from a further input A which is returned from phase locked loop APLC 02  to be compared in phase comparator PD 02  with a further reference signal. The final output from the receiving system is derived from an oscillator DI 00  which is phase locked by a further control loop APLC 01  to the output from loop APLC 00 . Further aerials and control systems may also be provided.

Abstract: 718,383. Engine stop gear. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 4, 1951 [Dec. 5, 1950], No. 28423/51. Class 122(4) [Also in Group XXXVIII] A device responsive to overspeed of an engine comprises a capacitor and a resistor series connected across a source of voltage the frequency of which is proportional to engine speed, a contact making microammeter or other voltage responsive device connected across the resistor responding at a predetermined speed i.e. when the impedance of the capacitor has been reduced sufficiently to increase the voltage drop across the resistor to a predetermined value to stop the engine. As shown, applied to a testing device for internal combustion engines, a push-button 25 is momentarily closed to energize a relay 22 which locks at 23, and, at 24, closes the ignition circuit through the ignition switch 12 and circuit breaker 13 to the ignition coil 15. The voltage thus applied by battery 10 to the ignition coil, pulsates at a frequency proportional to engine speed, and is applied across a capacitor 18 in series with a potentiometer 19. The capacitor impedance is preferably greater than that of the resistor 19 over the speed range in question, so that the voltage drop across the resistor is substantially proportional to speed. At a predetermined maximum permissible speed, a microammeter 21 connected across a portion of the potentiometer 19 closes contacts 21b to short circuit the relay 22 to open the ignition circuit at 24 and thus stop the engine. In another arrangement, Fig. 2, the pulsating voltage is produced by a moving contact 30, pivoted at 31 and oscillated between fixed contacts by a reciprocating part 29 of the engine, whereby the impedance combination 18, 19 is alternately connected across batteries 10a, 10b connected in opposition.
