Title: Improvements in or relating to the transmission of information
Inventor: BRICKNELL JOHN EDWARD HARVEY
IPC: H04B3/54
Filed: 1968-07-08
Abstract: 1,270,109. Signalling on trains. RIPPER ROBOTS Ltd., and BRITISH RAILWAYS BOARD. 8 July, 1969 [8 July, 1968], No. 32403/68. Heading B7N. [Also in Divisions H3-H5] In a train audio information is transmitted on a high frequency carrier over a circuit provided for another facility, preferably a train lighting circuit. The information preferably frequency modulates a carrier of about 30 KHz. As described power from the lighting control circuit is applied via a conventional series regulator circuit, transistor VT1 to VT5, Fig. 1A, to supply a constant voltage to power the transmitter, Figs. 1A and 1B. The microphone input signal from terminal F is amplified in a differential amplifier, VT6 to VT9, and applied via a compound emitter follower, VT10 and VT11, to frequency modulate a magnetic oscillator including transformer T1 and multivibrator, VT12  and VT13. The oscillator output is applied to the power amplifier, VT15 and VT16, for application to the train lighting control circuit, via a gate formed by diode D8 and transistor VT14 which prevents a signal being applied to the power amplifier until a short time after the equipment has been switched on, due to charging of capacitor C10. At the receiver, Figs. 2A and 2B power derived from the lighting control circuit at terminals C and D filtered and stabilized by Zener diode D6, while signals are applied via transformer T1 to operate a Schmitt trigger, VT1, VT2, which cleans up the received waveform and fires a monostable trigger VT3 and VT4 which supplies charging pulses to an integrator C6 and R14. The appropriate frequency compensation for the integrator characteristic is provided in transistor VT5 from which the signal passes to a conventional amplifier feeding a loudspeaker in the rail coach. The arrangement provides public address, music distribution or intercommunication through a railway train without the use of special wires.

Title: Improvements in or relating to a process of and apparatus for making soap
IPC: C11D19/00
Filed: 1935-11-25
Abstract: <PICT:0471172/III/1> In a continuous process for the manufacture of soap, a stream of saponified material is released into a chamber in which a partial vacuum is maintained, glycerine is continuously removed from the chamber as vapour and molten or plastic soap is continuously withdrawn, or the vacuum is maintained by the continuous removal of glycerine vapour whilst the soap is maintained in the molten or plastic condition until its removal.  Soap from cottonseed oil must be kept above 455 DEG  F. and soap from palm oil or tallow above 518 DEG  F., until it is removed from the chamber.  As shown, tallow, cottonseed oil, or other glyceride is pumped from a tank 11, and aqueous potash or other saponifying agent from a tank 22, to a mixer 14.  The pumps 1, 2 are driven through variable-speed gearing 18 set to deliver the materials in proper proportions. The mixture is saponified under pressure in the coil 4 and the resulting mixture of glycerine, steam, and soap is released through a nozzle 51 into a jacketed chamber 5 connected to barometric condensers 7 for the glycerine and 8 for the steam, and to a small vacuum pump 84. Superheated steam or hot inert gas may be admitted to the chamber 5 at 56.  The soap, which is free from water, and is of low glycerine-content, is removed by a pump 6 driven by variable-speed gearing 43, and any desired proportion of water may be mixed with the outflowing soap by a pump 3.  The soap is extruded at 97 by a screw-conveyer 94 driven by variable-speed gearing 95, and jacketed for cooling.  The pump 6 may be dispensed with.  If sufficient water is added to the soap, the extruded bar is a plastic solid, but if the proportion of water is less than about 12 per cent, a friable mass is produced which readily breaks into soap powder.  Specification 396,769 is referred to.
