Patent GB-185780-A (GB)
Title: Improved process and apparatus for gas purification
IPC: C10K1/34
Filed: 1921-04-07
Abstract: 185,780. Cox, K., Kerr, R. P., and Baty, E. J. April 7, 1921. Sulphur.- In the recovery of sulphur from gas the latter is passed through a contact material, such as oxide of iron, aluminium or manganese the temperature of the reaction being controlled by adding heat to or abstracting heat from the contact material and/or the gas so that deposition of sulphur on the material is prevented and the sulphur is carried by the effluent gases and collected in the elemental state. In one form of apparatus the material is supported on a grating D in a container A and the temperature is adjusted by the passage through a coiled pipe E embedded in the material of a heating agent such as steam, water, oil or cil vapours or cooling agents, the outlet of the pipe leading to a jacket c<1> surrounding the gas outlet C. Gas passes from an inlet B through the material to one or more cyclone extractors J in which the sulphur is deposited. A heat exchanger may be used to transfer the heat of the outgoing gases to the incoming gases. Air is usually supplied to the gas as it enters the reaction chamber. Specifications 3608/82, 5959/83, 13844/96, 20920/08, [Class 55, Gas manufacture], and 120,554, [Class 55 (ii), Gas manufacture &c.], are referred to.

Title: Improvements in gyro compasses
IPC: G01C19/38
Filed: 1940-06-12
Abstract: 542,529. Automatic control systems for gyrostatic apparatus. HOLMES, E. L., HUGHES, A. J., and HUGHES & SON, Ltd., H. June 12, 1940, No. 10245. [Class 38 (iv)] [Also in Groups XX and XXXVIII] Alignment.-In a gyro-magnetic telecompass a glass bowl 19 containing an electrolyte is mounted on the azimuthal (vertical) ring 103 of the gyro and supports on a pivot cup 18 two glass-sheathed permanent magnets 10. The glass sheaths carry electrodes 11 ... 14 cooperating with electrodes 20 ... 23 mounted in the bowl and connected to slip rings 31, 32, 33. If the gyro wanders and therefore the bowl 19 rotates relatively to the magnetic element, the relative displacements of the electrodes result in a differential alternating current from an appropriate source flowing through the electrolyte and thence by way of two full wave metal rectifiers to a relay coil which closes a direct circuit in order to operate a spring-returned valve. The movement of the valve causes compressed air to be directed through one or other of two nozzles in order to precess the gyro towards the average direction of the magnetic element. In order to indicate visibly that the directional gyro is synchronizing with the telecompass, a centre zero moving coil milliammeter is arranged in the rectified output circuit of the telecompass. Specification 409,027, [Group XX], is referred to in the Provisional Specification.

Title: Improvements in radio receivers
Inventor: BARTON CHARLES ARTHUR
IPC: H03F5/00
Filed: 1961-03-23
Abstract: 948,364. Transistor radio receiving circuits. PYE Ltd. March 15, 1962 [March 23, 1961], No. 10666/61. Heading H3T. The invention relates to the provision of automatic gain control for a television tuner T employing transistors and which derives its power supply from the voltage drop across a Zener diode D1 connected in the anode circuit of an intermediate frequency amplifier valve V1 to which automatic gain control is not applied. According to the invention, an automatic gain control voltage is derived from a resistor R1 in the anode circuit of a further intermediate frequency amplifier valve V2 to the grid of which an automatic gain control voltage is applied. The voltage at the point B may be applied via a potentiometer to the base of the radio-frequency stage transistor in the tuner T (Fig. 1, not shown); alternatively, delay may be introduced by means of a diode D2. This is conductive so long as the potential of the point B is below that of the point A, clamping the potential of the point C to that of point A; when the potential of B rises further, the diode becomes non-conductive and the potential at C, to which the base of the radiofrequency stage transistor is connected, follows that of point B. In a modification (Fig. 5, not shown), the tuner derives its supply potential from a Zener diode connected in the cathode circuit of an intermediate frequency stage valve and the automatic gain control voltage is derived from the cathode voltage of a controlled intermediate frequency stage. Instead of using the automatic gain control voltage to vary the base bias of a transistor, it may be applied to vary the impedance of a damping diode connected across a tuned circuit in the tuner. Specifications 918,931 and 948,363 are referred to.
Patent GB-422780-A (GB)
Title: Magnetic body, preferably for weak current purposes, and processes for its production
IPC: H01F1/16
Filed: 1933-04-10
Abstract: Magnetic cores, especially for weak currents, are built up of strips, wires, or sheets arranged parallel to the direction of the field and divided transversely to the field by layers of non-magnetic conducting material, which may extend wholly or substantially across the strips &c.  The non-magnetic materials may be copper, aluminium, chromium, or non-magnetic alloys of iron; or cobalt or nickel may be sufficiently non-magnetic for the purpose.  The strips, wires &c. may be drawn or rolled out of bars or ingots produced by arranging alternate layers of magnetic and non-magnetic material, and heating them until they unite; such heating may reduce the materials to a pasty condition but must not be sufficient to fuse them.  The non-magnetic layers are spaced at distances ten or more times greater than their thickness and greater than the distance between adjacent strips &c.  The thickness of the non-magnetic layers is preferably below ,1 mm. and may be below ,001 mm.  The non-magnetic divisions need not extend directly across the strips &c., but may be produced by coating a magnetic powder galvanically or otherwise with non-magnetic material and consolidating it by hammering, rolling, pressing &c.

Title: Demodulation circuits for frequency and phase modulated waves
IPC: H03D3/04
Filed: 1941-08-22
Abstract: 548,509. Frequency and phase modulation. STANDARD TELEPHONES & CABLES, Ltd. (Western Electric Co., Inc.). Aug. 22, 1941, No. 10731. [Class 40 (v)] A demodulating circuit for a frequency-modulated system comprises a magnetic harmonic generator converting the incoming waves into positive and negative pulses, those of one sign being suppressed or inverted, and the resulting pulses being integrated to produce the signal. For receiving phase-modulated waves the pulses are combined with an unmodulated carrier wave. As shown in Fig. 1, a frequency-modulated wave received on an aerial or line is heterodyned at 3 and fed through an amplifier 6 to a saturatedcore inductance 7 of the kind described in Specification 477,875, [Group XXXV]. The wave is thus converted into positive and negative pulses as indicated in Fig. 3. The negative pulses are suppressed by a rectifier 9 and the positive pulses pass through a large condenser C3 and a high resistance R,. A low-pass filter 11 connected across the resistance R3 eliminates high-frequency components and passes the integrated signal current to an amplifier 12 and receiving device 17. Variations in pulse amplitude are eliminated by connecting across the condenser C3 a silicon carbide resistance 14 or a pair of reversely-connected diodes or copper-oxide rectifiers. Instead of suppressing the negative pulses, they may be converted to positive pulses by the use of a rectifier bridge (Fig. 2 not shown). For receiving phase-modulated waves, Fig. 6, the positive pulses from the inductance 7 pass to a modulating-device 13 where they are combined with a wave from a source S of the same frequency as that applied to 7 and with its phase so adjusted that the resultant output is proportional to the phase displacement of the incoming wave and therefore represents the signal. The auxiliary wave S may be sent out from the transmitting station or a control station ; it may be of saw-toothed form, and its frequency may be a harmonic of the carrier.
