Title: Improvements in or relating to alternating current signalling systems
Inventor: HARGREAVES THOMAS FREDERICK ST
IPC: H04Q1/446
Filed: 1947-04-30
Abstract: 651,461. Voice frequency receivers. STANDARD TELEPHONES & CABLES, Ltd. April 30, 1947, No. 11605. [Class 40 (iv)] In a voice frequency receiver comprising rectifying means to produce from the incoming signal, two D.C. signals of different amplitude having different times of build up and decay and rectifying means to derive a guarding potential, the outputs from the former two are connected in series opposition to give a nett signal of similar duration to the initially received signal, and the guard potential renders an apparent signal ineffective if frequencies other than signal frequencies are present and exceed a predetermined limit. The D.C. signals of different amplitude are obtained by means of rectifier networks VD1, VD2, Fig. 4, which are fed from the secondaries T1a, T1b of the input transformer T1, T1a, having twice as many turns as T1b and being tuned by a condenser C2. The voltage across A-B (curve (iv), Fig. 5), is used to charge a condenser C1 through a resistance R1 which is shunted by a rectifier W1 to provide a quickdischarge circuit and consequently the voltage across E-F (curve (vi)) rises more slowly than that across C-D (curve (v)) but decays more rapidly. In a complete two-frequency receiver, Fig. 14, the pairs of rectifier networks VD1, VD2 and VD3, VD4 are fed respectively by input transformers T1, T2, while a further network VD5 fed by an input transformer T3 for non-signalling frequencies is connected in parallel with VD2, VD4 via rectifiers, so that the guard potential produced is ineffective until it exceeds the potential developed by VD2 or VD4. Rectifiers W5 and W6 feed part of the back bias from VD2 to VD4 and vice versa to oppose potentials due to the filter inefficiency in the non-working circuit when only one circuit is working. Rectifiers W2 serve to hold the points C at earth potential when no signal is being received but are biassed to be ineffective when the potential across Rc which also provides standing bias to V2 and V3 is overcome by the output VD2 or VD4. The potential across resistance RD backbiasses VD2, VD4 to compensate for the difference in contact potential between the rectifiers of the signal and back-bias circuits at low inputs. When the receiver is connected in the receiving channel of a 4-wire line where a common speech and signal amplifier is used, as described in Specification 651,457, the speech output transformer and the transformers T1, T2, T3 are all in series and interference by speech received backwards is prevented by the high impedance of the amplifier valve, Fig. 15 (not shown), or the speech output transformer may be tapped to form a hybrid circuit, Fig. 16 (not shown). The Provisional Specification describes another arrangement in which the rectifier networks are all in series and the primaries of the transformers T1, T2 and T3 are tuned.

Title: Improvements relating to direction finding radio receiving apparatus
IPC: G01S3/06
Filed: 1941-09-13
Abstract: 551,947. Direction-finding radio apparatus. COSSOR, Ltd., A. C., and STRAFFORD, F. R. W. Sept. 13, 1941, No. 11747. [Class 40 (v)] To provide for sense-determination in direction finding systems comprising symmetrical two-element directional aerial arrays 1, 2 and electrically symmetrical feeder systems 3, 4, 6 between the aerial array and the receiver 5, switching means are provided whereby the feeder system can be rendered asymmetrical so that a further position of minimum response can be found by re-orientation of the aerial array. As shown, vertical half-wave dipoles 1, 2 separated by a half wave length are connected in opposition by quarter wave-length feeders 3 and 4, the junctions of which are connected by a further feeder 6 to the receiver. An additional feeder 7 is connected to a tapping on the feeder 4, preferably at a point one-third the length of the feeder from the junction with the other, and a switch 8 allows either the feeder 6 or 7 to be used. After a determination of direction in the usual way, for which the' feeder 6 is in circuit, the feeder 7 is substituted and the array is given a further rotation to a new position of minimum or zero response. Since in this position signals from the two dipoles arrive at the junction of the feeders 4 and 7 in phase, and since those from the dipole 1 have the longer path to travel, the dipole 1 will have been turned towards the direction from which the signals are arriving so that. they reach it in an earlier phase than in the case of the dipole 2. The sense of the incoming signals is thus determined. The feeders 6, 7 are preferably arranged to present a substantially open circuit at their junctions with the feeders 3 and 4 when out of use, for which purpose they may have electrical lengths of an integral multiple of a half-wave length and be open-circuited by the switch 8, or an odd multiple of a quarter wave-length, in which case the switch shortcircuits the feed not in use. In modifications, the feeders 3, 4 extend to a point adjacent the receiver, the length of the feeders 6, 7 being rendered so short as to be immaterial. In one such form, one feeder is longer than the other, the extra length being short-circuited, when determining the direction of the signals.

Abstract: 1,005,295. Pulses radar. VARIAN ASSOCIATES. March 25, 1963 [April 2, 1962], No. 11752/63. Heading H4D. A microwave system comprises a parametric amplifier 5 including a varactor, a circulator 1 for supporting the amplifier with, and removing therefrom, a received radio signal, a klystron pump frequency energy source 6, a varactor-bias supply 8 and means for applying the bias voltage, in the event of removal of the pump signal from the varactor, in such a manner as to maintain a substantially constant phase angle of the received radio signal in the parametric amplifier and to reduce insertion loss of the signal. The embodiment incorporates a solenoid-operated attenuator 7, a waveguide power splitter 9 (see also Figs. 2 and 3, neither shown), ferrite isolators 15 and variable attenuators 16 for adjusting pump level input to the parametric amplifiers 5, and is applied to a monopulse radar aerial network from which signal inputs arrive via circulators 1 and are coupled into the varactor cavities of the parametric amplifiers which may be of the non- degenerate, reflection, self-biasing kind. The phase angle and insertion loss of each varacter cavity is maintained at a constant level by automatic and simultaneous application of varactor bias from power supply 8. The use of parametric amplifiers improves the noise factor of the radar receiver.

Solid carbonaceous material, e.g. shale coke, is gasefied in two stages each fluidized, air being used as gasefying agent in the first stage wherein the temperature of the material is raised to between 850‹ and 950‹ C. before passing to a second stage employing a mixture of steam and oxygen as the gasefying agent, the temperature in the second stage being between 900‹ and 1000‹ C. Heat may be recovered from the gas produced in the first stage in a waste heat boiler and the heat of the residue from the second stage may be used to raise steam or the residue may be combusted if the initial material contained sulphur to produce sulphur dioxide. The process may be combined with a fluidized shale distillation process shale coke being passed from the distillation zone to the first gasefication stage and hot shale coke passed back from the first gasefication stage to the distillation zone to supply the heat for the distillation.

Abstract: 432,303. Refractory compositions. KONOPICKY, K., 1, Hirschengasse, Vienna. April 19, 1934, No. 11845. Convention date, April 19, 1933. [Class 22] A method of producing sintered ferruginous magnesia, the total quantity of fluxing agents (certain or all of lime, silica, alumina) in the sintered product being greater than 2 per cent but not greater than about 12 per cent, consists in adjusting the relative proportions of lime &c. in the ferruginous magnesia, e.g. by adding these oxides or magnesia material containing them, so that the said proportions fall within the area A B C of the ternary diagram shown, and then firing the mixture. Preferably, the proportions are adjusted so as to fall within the area D E N M. The quantity of iron oxide preferably amounts to at least one and a half times the quantity of lime. In an example, to 1 part of a magnesite containing 0À4 per cent of lime, 3À2 per cent of silica, 0À6 per cent of alumina and 0À2 per cent of ferric oxide (corresponding to position 1 of the diagram) are added 1À5 parts of a sintering magnesite containing 3À4 per cent of lime 0À7 per cent of silica, 0À7 per cent of alumina and 9À1 per cent of ferric oxide (corresponding to position 2) to obtain a still good sinter having its lime-silicaalumina proportions represented by position 2<1>. Other examples are given. Specification 394,115 is referred to.

Abstract: 1534063 Separating coatings on material GRANGES ESSEM AB 24 March 1976 [25 March 1975] 11910/76 Heading C7D [Also in Division F4] In a method for the separation of coatings on material by heating (e.g. destruction of paint and varnish from aluminium plates) material from which coatings are to be separated is heated in an oven chamber 11 by some of the gases produced by a burner 22 in a combustion chamber 12. The gases produced are at a temperature sufficient to evaporate substances forming the coating of the material in the oven and contain insufficient oxygen to permit substantial burning in the oven. A fan 15 forces the vapours generated plus the heating gases from the oven to the combustion chamber. A long flame is formed by fuel and primary air from the nozzle 22 and secondary air supplied through the space between the walls of the screen tube 23. Gases from the oven chamber flow past the tube 23 and are guided by the plates 25 to flow longitudinally round the periphery of the combustion chamber and round the outer part of the flame without deflecting it. Vapours generated in the oven are thus burned in the high temperature outer layer of the flame and destroyed. Part of the gas from the combustion chamber is diverted to atmosphere by a conduit 17 which is smaller than the conduit 14 so that the quantity of gas recirculating is larger than that diverted to atmosphere. The process is regulated by the fuel and air supply to the combustion chamber which controls the temperature of circulating gases.

Abstract: 1,014,769. Recording temperature. BARNES ENGINEERING CO. March 23, 1964 [April 11, 1963], No. 12089/64. Heading G1J. [Also in Division H4] In order to determine the temperature of an object by the intensity of infra-red radiation it emits, an infra-red camera is arranged to provide an image of the object together with an image of a calibrated temperature source which is positioned next to the object so that the depth of greyness of the image corresponding to the objects temperature is compared alongside the image of the calibrated source. As shown in Fig. 1, the infra-red camera 10 comprising a rotatable plane mirror 12 and a parabolic mirror 14 is so arranged in front of an object and calibrated source 60 that an infrared detector 18 which detects the infra-red radiation from a part of the field of view provides an A.C. current of such amplitude that a light source 36 fed with this current produces on a photographic plate 42 an image whose greyness is proportional to the intensity of the infra-red radiation. The calibrated temperature source may consist of a number of individual sources in the form of hot plates which are each heated electrically to known temperatures. Alternatively it may consist of a single hot source whose infra-red radiation corresponds to the highest temperature of the object, and by then suitably filtering different parts of the source or, as shown, by suitably alternating the current produced by the hot source radiation, images whose greyness correspond to known lower temperatures may be obtained. The calibrated temperature source may be provided with means (Fig. 4, not shown) for identifying different thermal pictures taken with the infra-red camera.
