The apparatus for recording on successive record discs of a stack of discs as described in Specification 723,193 and the stack are modified in that successive discs 5 are linked by a tab 16 of one being inserted in a slit 17 of the next instead of being linked by an adhesive strip and in that the knife for severing the strip is replaced by a thin springy finger 12 for lifting the top disc at the end of each revolution until the tap 16 slips out of the slit 17. The stack lies between two flanges on a sleeve 7 so that if a disc is unofficially removed, torn pieces will disclose the fact. A cap 9 is held on a shaft 4 by a bayonet fastening and a spring 10 presses the stack of discs 5 on to pins 29 in a drive disc 3 in one with the shaft 4 and constant speed drive shaft 2.

Abstract: 1,152,362. Automatic alarm systems. PATRICK & DREW Ltd. 12 May, 1966 [12 May, 1965; 25 March, 1966], Nos. 20119/65 and 13313/66. Heading G4N. A fire or burglar alarm includes a transducer which may be a temperature, flame or smoke detecting device or a microphone connected to amplifiers which respond to a change in transducer output to produce a signal which energizes a relay coil 81. When coil 81 is energized it actuates relay contacts 82 to allow current to pass through variable resistor 90 which is preset so that operating current changes by an amount sufficient to actuate one or other of relay coils 93, 94 to actuate an alarm 97. Opening any one of switches 86, 87 associated with doors or windows, or with a cover of alarm apparatus, also actuates alarm 97. The alarm may be disabled by a switch 102. A resetting switch 103 is also provided. In a modification shown in Fig. 5, the presence of an intruder is sensed by a microphone 11<SP>1</SP>. A signal along line 12<SP>1</SP> changes the current in the primary of the output transformer of the pushpull amplification stage of an amplifier 13<SP>1</SP> and hence in the secondary winding of the output transformer which affects the current flowing in coils 23<SP>1</SP>, 24<SP>1</SP> of relays 25<SP>1</SP>, 261. These relays have fixed contacts 27<SP>1</SP>, 28<SP>1</SP> and a movable contact 30<SP>1</SP> which is preset so that when a predetermined current passes through relay coils 23<SP>1</SP>, 24<SP>1</SP> movable contact 30<SP>1</SP> is mid-way between contacts 27<SP>1</SP>, 28<SP>1</SP>. When an intruder causes current in coils 23<SP>1</SP>, 24<SP>1</SP> to differ from the predetermined value, contact 30<SP>1</SP> will be connected to lead 291 through fixed contact 27<SP>1</SP> or 28<SP>1</SP>. Lead 29<SP>1</SP> is connected to a further relay 37<SP>1</SP> which is thus energized to sound hooters 47. The temperature sensitive device may comprise a fusible conductor in line 22<SP>1</SP> arranged to melt at a predetermined temperature.

Abstract: 528,337. Coking processes. GAS ENGINEERS, INSTITUTION OF, and DENT, F. J. May 4, 1939, No. 13349. [Class 55 (i)] Carbonization is initiated in a portion of the charge in a pressure vessel by a local supply of heat which is subsequently reduced or discontinued, the heat evolved by carbonization in one portion of the charge being transferred by circulating gases to another portion so that a zone of high temperature (600‹ to 1000 ‹C. dependent on the pressure) travels through'the mass. The pressure maintained is at least 25 atmospheres. The gas is circulated by a pump 2 through the vessel 1 which may be of the kind described in Specification 519,246, and back through a condenser 3, liquor being withdrawn through a pipe 4 and surplus gas through an offtake 5. The coal may be preheated to 200‹ to 300‹ C. before use, and the local rise in temperature may be produced by temporarily preheating the circulating gas. When fusible coal is used it is charged in an annular mass round a central core of coke which is heated electrically to initiate carbonization.

Abstract: 1305145 Carbon or graphite felt SIGRI ELEKTROGRAPHIT GmbH 5 May 1971 [3 June 1970] 13355/71 Heading C1A A carbon or graphite felt is produced by heating a felt formed from fibres of a carbon containing synthetic or natural polymeric material to a temperature sufficiently high to effect carbonization, or carbonization and graphitization of the felt, this carbonization or carbonization and graphitization being performed in an inert atmosphere or a reducing atmosphere, the felt being subjected to tensile stress during at least part of the time it is being heated. The tensile stress applied amounts to from 25 to 75% of the tensile strength of the felt in the temperature range in which the tensile stress is being applied. Preferably the stress is applied for only part of the temperature range traversed during the heating from ambient to carbonization or graphitization temperatures. Thus the stress may be applied at temperatures in the range from 200-300‹ C. or 300-1000‹ C., or 1000‹ to 3000‹ C. The starting material may be made from cellulose, polyacrylonitrile, or wool fibre.

Abstract: A mineral oil distillate is hydrogenated, and then separated into paraffins, naphthenes and aromatics by adsorption on a solid adsorbent, for example, silica gel.  The separated fractions may thereafter be subjected to further treatment with oleum and fuller's earth.  The hydrogenation renders any sulphur, nitrogen, oxygen and olefin compounds innocuous in the adsorption step, and may be effected at 250-400 DEG  C. and 5-150 kg./cm.2  The preferred catalyst is NiS.WS3.Al2O3.  The hydrogenated product may be stripped with steam or nitrogen at elevated temperatures.  The paraffins and naphthenes may be successively eluted from the adsorbent by a low molecular weight aliphatic hydrocarbon, such as pentane, and the aromatics by a low molecular weight aromatic hydrocarbon such as benzene.
