Abstract: 550,537. Wireless signalling ; aerials. MARCONI'S. WIRELESS TELEGRAPH CO., Ltd. July 10, 1941, No. 8755. Convention date, July 10, 1940. [Class 40 (v)] An antenna comprises a rod-like radiator 11 having a. disc 19 mounted at the energized end to increase its capacity. The radiator 11 may have a tapered portion 16 arranged within a tapered sheath 15, the numbers 15, 16 being connected to a concentric transmission line 13, 14. The ratio of the diameter of conductor 16 to the bore of the sheath 15 is constant, so as to prevent reflection effects. The tapered sheath 15 is surrounded by a cylindrical shell 17 connected to 15 at its outer end. A conductor 23 connects the edge of the disc 19 to the supporting structure 20, thereby earthing the radiators against lightning &c. The disc 19 and the radiator 11 are each adjustable, Two or more of such radiators may be disposed at equal angles in a common plane and energized in such a way as to produce a rotating field, and-additional similar radiators may be arranged in parallel planes half a wave-length apart, Fig. 8 (not shown). The aerials may be energized simultaneously with two different wavelengths, e.g. by audio and video signals in television, the phase rotations of the two signals being in opposite directions. Fig. 9 shows an arrangement of this kind, the antenna 100 comprising four quarter-wave radiators in each of two planes energized with suitable phase displacement over four transmission lines 68 ... 71. The audio-transmitter A supplies energy to a pair of transmission lines 25, 25<1> and 26, 26<1> differing in length by half a wavelength, the load ends of the lines being turned to face each other, cross-connected as shown and surrounded by a shell 27, half a wavelength long and connected at its ends to lines 25, 26. A pair of balanced output lines 45, 46 and 55, 56 is connected to adjacent ends of the sheaths 25, 26, so that energy from transmitter A is supplied in push-pull relationship to the output lines. The video-transmitter B energizes a single transmission line 35, 36 connected through quarter-wave lines 28, 28<1> to the shell 27 and lines 25, 26, so that energy from B is supplied in push-push to the lines 45, 55. A loop 47 in one of the output lines ensures that energy in phase quadrature is obtained at their far ends, the phase rotation being in opposite directions for the two transmitters. Specification 528,817 is referred to.

Title: Method of manufacture of materials required in the electrometallurgy of aluminium
IPC: C01F7/54
Filed: 1945-04-10
Abstract: Pure carbon for electrodes and double fluoride of sodium and aluminium for electrolytes are produced by treating granular coals yielding mainly silicious ashes with aqueous hydrofluoric acid preferably at about 70 DEG  C. until the ash yield falls below 1 per cent, treating the resulting fluosilicic acid with common salt to produce a precipitate of sodium fluosilicate and a solution of hydrochloric acid, and heating the washed sodium fluosilicate with alumina to produce silica-free double fluoride of aluminium and sodium.  The hydrochloric acid may be used to eliminate iron from coals used to make anodes for manufacturing silicon-aluminium alloys. The sodium fluosilicate may be heated with alumina in aqueous suspension or at 500 DEG  C. dry to produce 2 AlF3.3NaF or at 500 DEG C. with added sodium carbonate to produce 2 AlF3. 6 NaF.  The double flouride and silica may be separated by flotation or by the method of Specification 589,944.  The treated coal is washed, dried, heated at 1300 DEG  C. to expel gases and form a coke suitable for electrodes. Specification 270,703, [Class 50], also is referred to.

Title: Improvements relating to intrusion detectors
Inventor: ORRIN JOHN NOEL
IPC: G08B13/194
Filed: 1968-02-23
Abstract: 1,261,207. Intruder alarms. EMI Ltd. 10 March, 1969 [23 Feb., 1968], No. 8864/68. Heading G4N. An intruder alarm comprises a scanning heat or light-sensitive sensor 2 whose output signal is stored and then compared in a differential amplifier 14 with a subsequent output signal direct from sensor 2, any difference in the signals being used to trigger an alarm 21 and thus indicate the presence of an intruder. The sensor output is modulated at 12 so that it can be recorded on a magnetic tape 10. Tape 10, recording head 13 and reading head 15 are arranged so that either consecutive scanning signals or signals ten scanning periods apart may be compared at differential amplifier 14 to which the signal from the reading head 15 is fed after being demodulated at 16 and amplified at 18. Alternatively, two tapes may be used, one providing comparisons between consecutive signals and the other between signals ten scanning periods apart. An erase oscillator 23 is provided. Tape 10 is mounted on a drum 7 which is driven together with sensor 2 by a shaft 1 of a motor 6. A lamp 3 and commutator 8 may also be driven by shaft. Lamp 3, a xenon flash tube or a gallium arsenide laser, either operates continuously or is operated by pulses from commutator 8 suitably modulated at 9. If the shaft 1 rotates at 3 rev. s<SP>-1</SP>, lamp 3 provides 216 pulses s<SP>-1</SP> of a beam extending 5 degrees laterally and 35 degrees vertically, the upper boundary of the beam being horizontal (Fig. 2, not shown). Reflected parts of the beam are detected by sensor 2 having a similar beam width but inclined below the horizontal. Upwardly directed beams may also be used. The optimum range of the beams is about 20 feet. The lamp 3 is dispensed with if the sensor is of the type responsive to infra-red radiation from the intruder. In an alternative embodiment, the sensor output is stored in a reed-switched commutated sequence of charging resistors and capacitors, each capacitor corresponding to a sector of the scanned region. By this method, consecutive scans only can be compared unless the angular velocity of the commutator relative to the sensor is varied.

Filed: 1925-04-03
Abstract: 254,397. Marks, E. C. R., (Morkrum Kleinschmidt Corporation.). April 3, 1925. Type-printing telegraphs.-A single magnet controls the selecting mechanism and also the supply of energy to the motor. The circuit of the motor is opened by the transmission of a particular code signal, such as the blank signal which is also used to ring a bell, and is maintained open by a catch controlled by the selecting magnet. In a modification, the motor circuit is controlled also by contacts operated by the printer shift mechanism. Lamp signals, auxiliary to the bell signals, serve to distinguish important calls. Control of motor circuit. The actuating bars 108 are selected bv notched selector bars 59 - - 63 under control of the normally energized selector magnet 8 as described in Specification 218,643. The movement of the bell signal actuating bar 108<1> causes the arms 303, 305 to move the member 306 to the right as shown in Fig. 3, thereby opening contact 318, 320 in the circuit of the motor 329. As the magnet 8 remains energized at the end of the signal, the member 306 is locked in its operated position by the engagement of its latched end 310 with an extension on the armature of the magnet 8. When the line circuit is interrupted, which occurs at the commencement of each signal, the latch is released and the parts 303, 305, 306 restored to normal by a spring 304 to close the motor circuit. The motor circuit may also include, in parallel with contacts 318, 320, contacts 326, 327 controlled by the shift mechanism 265, in which case the motor circuit is only opened by sending the shift signal followed by the bell signal. Signalling arrangements. If the bar 108<1> is utilized to operate a bell signal and also to operate arm 303, the bell will ring and the motor circuit be opened each time the bell key is depressed and released, since the depression of any key releases the latched member 306 by momentarily opening the circuit of magnet 8. Bell signals may also be sent by automatic transmission. A signal lamp 334 is lit over contacts 338, 327, 326 each time the member 306 is moved to the right by the depression of the bell signal key, and is extinguished by the depression of a character key which releases the member 306. Urgent signals are indicated by the flashing of the lamp followed by prolonged lighting thereof, while other signals are given by flashing of the lamp only. The apparatus may be modified for open circuit working.
