Title: Improvements in and relating to electric carrier telegraph systems
IPC: H04L1/04
Filed: 1949-04-06
Abstract: 665,654. Radio signalling; multiplex signalling. BRITISH TELECOMMUNICATIONS RESEARCH, Ltd., and TERLECKI, R. March 15, 1950 [April 6, 1949], No. 9426/49. Drawings to Specification. Class 40 (v). In a frequency or phase-shift carrier telegraph system a pair of carriers is transmitted for each mark and space signal, and the difference in frequency between the carriers is made unequal or, if equal, the two pairs produce by beating at the receiver oscillations of different relative phase. A smaller frequency difference is thus possible and at the receiver a local oscillator unnecessary. A single pair of oscillators with common aerial may be used, and one or both shifted in frequency or phase during keying in the same or opposite directions, e.g. by a relay acting on a modulator. If one only is modulated, it may be of low frequency and raised to a frequency near that of the other unmodulated oscillator by heterodyning with a further oscillator. Additional phase or frequency shifted low-frequency oscillators may be employed in conjunction with a common frequency raising heterodyne oscillator and the oscillations, in conjunction with adjacent frequency oscillations, used for multiplex or frequency diversity signalling. The output stage may be a frequency multiplier. In a phase-shift circuit, Fig. 10 (not shown), an oscillation input valve 29 has two cathode circuits of unequal reactance between tappings of which a tuned output circuit 34 is connected. A modulator valve 36 is cathode coupled across one resistor in one of the two cathode circuits of valve 29 and dependent on the keyed voltage on the grid of the modulator valve 36 the phase of the output oscillation in tuned circuit 34 is varied or reversed.

Title: Improvements in or relating to arrangements for the stereophonic reproduction of signals
IPC: H04S1/00
Filed: 1960-03-18
Abstract: 926,357. Stereophonic reproduction. PHILIPS ELECTRICAL INDUSTRIES Ltd. March 18, 1960 [March 23, 1959], No. 9691/60. Class 40 (5). For stereophonic reproduction of a sum signal A+B modulating a main carrier in frequency and a difference signal A - B modulating a sub-carrier frequency in amplitude, the I.F. stage of the receiver passes the signals to an output band-pass filter 4, 5 forming part of a frequency detector which includes rectifiers 6, 7 and an output impedance 8. The output is taken from the centre tapping of resistor 10 and applied to device 16 which recovers the coherent signals A and B and supplies them through separate low frequency amplifiers 17, 18 to reproducing speakers 19, 20. The device 16 comprises two amplitude detectors, i.e. rectifier cells 31, 32 connected in parallel with opposite polarities and each with output impedances comprising parallel resistors 33, 34 and capacitors 35, 36. The audiofrequency sum signal A+B acts as a threshold voltage for the two rectifiers 31, 32, which together with an amplitude detection of the envelope signal A - B produces at the output stages 33, 35 and 34, 36 respectively an addition and subtraction of the audio-frequency sum and difference signals A+B and A-B. The resultant A and B signals are fed through blocking capacitors 29, 30 to the triodes 17, 18 having negative feed-back. A series resistor 39 at least equal to one-quarter-one-third of the value of discharge resistors 33, 34 reduces detection distortion. Cross-talk reduction is achieved by a resistor 40 and shunting capacitor 15 connected across the output circuits of detectors 31, 32, their time constant being approximately equal to those of output impedances, and the voltage division ratio equal to the cross-talk factor. Similar and additional positive cross-talk correction is given by a variable resistor 41 connected between the cathode resistors of triodes 17, 18. If the sum signal A+B is supplied alternatively with opposite phase to each of the two amplitude detectors, e.g. using a frequency detector connected in push-pull, the amplitude detectors may be connected with the same polarity. A switch 42 connects the output circuits for non-stereophonic reproduction. The arrangement is suitable also for magnetic tape reproduction. In Fig. 2 (not shown), the receiver is transistorized.

A header assembly 11 having groundengaging skids 13 (Fig. 1 not shown) is adjustably supported on the main frame of a combine harvester 10 by means of a pivot and jack 12 the pressure of fluid within which is controlled by a valve 14 to transfer a proportion of the weight of the header to the main frame. The valve 14 comprises a stem 17 with two lands 15, 16 cooperating with ports 23, 24 for supplying pressure fluid to the ram and with ports 25, 26 connected respectively to a pump supply and a reservoir. A further valve 29 is spring-biased to close the connection to reservoir if the supply pressure drops but normally the valve is held open by the pressure of the supply. In operation the piston valve is set to the neutral position shown, by manual movement of screw 20. With an increase or decrease in pressure in the ram, due to undulations in the ground, the fluid operating through port 27 raises or lowers the pressure in chamber 28 to move the piston valve so that pressure fluid is either withdrawn or supplied to the ram in which the pressure is thus kept substantially constant to effect a constant weight transfer.

Abstract: 860,958. Preventing corrosion. IMPERIAL CHEMICAL INDUSTRIES Ltd. April 17, 1959 [March 27, 1958], No. 9931/58. Class 123(1) Corrosion of water cooling systems and the tanks of tanker vessels carrying sea water ballast is inhibited by adding to the water minor amounts of a composition consisting of an alkali salt of a carboxylic acid containing an aromatic or a cyclic aliphatic group, an alkali metal nitrite and an alkali metal borate or phosphate to act as a buffer agent. The carboxylate is preferably a sodium salt of an acid from one of the following groups:-unsubstituted aromatic acids, e.g. benzoic acid; acids as in the first group containing an alkyl substituent, e.g. 4-methyl benzoic acid; acids as in the first group containing an alkoxy substituent, e.g. 4-methoxy benzoic acid; unsubstituted acids produced by the partial or complete hydrogenation of acids as in the first group, e.g. hexahydrobenzoic acid; acids as in the last group containing an alkyl or alkoxy substituent, e.g. 4-methyl cyclohexane carboxylic acid; acids in which an aromatic group is separated from a carboxylic acid group by an aliphatic grouping, e.g. phenyl acetic acid; acids as in the last group containing an alkyl or alkoxy group in the 4-position to the side chain; acids as in the last two groups in which the aromatic nucleus has undergone partial or complete hydrogenation, e.g. hexahydrophenyl acetic acid; acids having the structure Ar-OCH 2 COOH where Ar is an aromatic radical, e.g. 4-nonyl phenoxy acetic acid; the cyclohexyl ether of glycollic acid or substituted derivatives thereof containing alkyl or alkoxy groups, e.g. cyclohexyl glycollic acid and finally acids as in the last group except that hydrogenated aromatic radicals other than cyclohexyl are employed, e.g. decahydro-2-naphthoxy acetic acid. When the inhibitor is used in cooling systems at elevated temperatures, e.g. 80-90‹ C., of the metal surface the carboxylate is present in the proportion of from 1% by weight when a salt of an acid of low molecular weight, e.g. sodium benzoate, is used to 0À02% when a high molecular weight salt such as sodium para-nonyl phenoxyacetate is used, sodium nitrite and sodium borate each being present in the proportions of 0À1 % by weight. When employed under cold conditions, e.g. in sea water ballast tanks, the proportion of carboxylate is increased up to 5 % and the nitrite and buffer agent to 0À5%. Small amounts of calcium and magnesium salts may be admixed with the inhibitor, where these salts are not present in the water, to increase the efficiency thereof.

Title: Switched optical network
Inventor: SMITH DAVID WILLIAM
IPC: H04B10/27
Filed: 1996-07-18
Abstract: Signals from transmitter stations are connected to receiver stations by a switched optical network. To provide a readily expandable, non-blocking network for a large network, groups of transmitter signals are formed into distinct optical wavelength multiplexes each of which is coupled by an optical fibre bus (4) to one input of each of several optical space switches (SW). Each receiver station is connected to an optical heterodyne receiver optically coupled to an output of one of the optical switches (SW). The required signal from the multiplex switched to an optical receiver is demultiplexed by combining with the multiplex an optical source (O) which has been frequency shifted by a frequency shifter (12). This is achieved by means of a secondary optical space switch (SW min ) and an optical combiner (14). The optical space switches (SW, SW min ) are controlled by a controller (6) to effect the desired connection.
