Title: Improved liquid-fuel supply means for appliances for producing and delivering heated air
Inventor: GLOVER DENYS THOMAS
IPC: F24H3/02
Filed: 1950-10-12
Abstract: 685,245. Supplying liquid fuel to burners. DANIEL & CO., Ltd., D. A. Aug. 31, 1951 [Oct. 12, 1950], No. 24888/50. Class 75(i) In a system for varying the supply of liquid fuel to an air heater a plurality of fuel supply conduits 1, 2 are provided, each having a spring-controlled supply valve 3 or 4, and leading to a separate outlet control 14 or 16 which enables selection of the supply conduit to be made, the supply valves 3, 4 being controlled by springs 22, Fig. 5, of different strength so that the conduits 1, 2 each supply a different amount of fuel in any given time. As shown, each supply conduit 1, 2 is fed from a common inlet 7 and filter 6, and beyond the respective supply valves 3, 4 the conduits branch into outlet conduits 8, 9 and 12, 13 respectively, each with an outlet control 14, 15 and 16, 17. The outlet controls, 14, 16 and 15, 17 feed into common outlet lines 10, 11 respectively, each leading to a separate heater so that each heater may be fed via either supply conduit 1 or 2 by operation of the outlet controls. The supply valves 3 and 4 are of the same construction, apart from spring strength, and are shown in Fig. 5. Each valve comprises a casing 18 partitioned by a diaphragm 21 into two compartments 19, 20, the lower one 20 of which receives the liquid fuel via an inlet 24 and valve passage 26 and discharges it through a passage 27 and an outlet 25. The upper chamber 19 houses the spring 22 which bears on the diaphragm 21 to urge a valve 28, in the lower chamber passage 26, away from its seating 30 and allow flow of fuel through the valve. The pressure of the fuel in the chamber 20 acts on the diaphragm 21 against the spring 22 to tend to raise the diaphragm and allow valve 28, under the action of a follower spring 31, to move towards its closed position. The extent of the closure of valve 28 depends on the strength of the spring 22. The outlet controls 14-17 may comprise solenoidoperated valves and may be housed, together with valves 3, 4 and filter 6, in a common casing provided with a drain cock. The Provisional Specification states thatt the solenoid-operated outlet controls may be thermostatically or manually controlled. Sepcification 616,006, [Group XIII], is referred to.

IPC: C09C1/16
Filed: 1935-09-10
Abstract: A basic lead carbonate pigment is precipitated by carbon dioxide from dilute solutions of basic lead acetate in the presence of dyes or dyestuff intermediates.  Dilute solutions of intermediates containing carboxyl, hydroxyl, or sulphonic acid groups, for instance b -hydroxynaphthoic acid, anthranilic acid, and p-nitrobenzoic acid may be employed in amounts of 0,5 to 2 mols. of intermediate to 100 mols. of basic lead acetate.  Dyes may be added to the acetate liquor when, like eosin, erythrosin, or Rose Bengale, they are soluble therein, or otherwise as in the case of tartrazine O be added as a dilute solution during precipitation.  Preferably, acetate solutions containing 1,6 to 2,8 per cent of lead are used and precipitation effected at 20--30 DEG  C.  A dilute solution of a salt of zinc, calcium, lithium, magnesium, barium, cadmium, strontium, or thorium having an acid radicle, such as acetate, nitrate &c., which will not form an insoluble compound with lead may also be added during precipitation.ALSO:A basic lead carbonate pigment which may be used as a substitute for pearl essence is obtained by passing carbon dioxide at ordinary pressure into a solution of basic lead acetate having a concentration of 0,5--6,0 per cent of lead at a temperature of 5--85 DEG  C. until the reaction mixture is slightly acid, and separating the precipitate.  Preferably acetate solutions containing 1,6 to 2,8 per cent of lead are used and precipitation is effected at 20--30 DEG  C.  The washed precipitate may be dehydrated by alcohol, acetone, &c.  The lustre of the pigment may be enhanced by adding during precipitation a dilute solution of a salt of zinc, calcium, lithium, magnesium, barium, cadmium, strontium or thorium having an acid radical, such as acetate, nitrate, &c. which will not form an insoluble compound with lead; about 1 to 6 mols. of added salt are used to 100 mols. of basic lead acetate.  Dyestuff intermediates containing carboxyl, hydroxyl, or sulphonic acid groups, for instance b -hydroxynaphthoic acid, anthranilic acid, and p-nitrobenzoic acid, may also be added to increase the lustre; dilute solutions are employed in amounts of 0,5--2 mols. of intermediate to 100 mols. of basic lead acetate.  Dyes may also be present, and may be added to the acetate liquor, when, like rosin, erythrosin, or Rose Bengale, they are soluble therein, or otherwise as in the case of tartrazine O be added as a dilute solution during precipitation. Examples of procedure are given.  Specifications 215,45/91, 7631/92, and 6439/05, [all in Class 1], are referred to.

Title: Improvements in or relating to frequency stabilisation of continuous wave radar systems
IPC: G01S7/03
Filed: 1956-08-24
Abstract: 802,008. Radar; radio receiving systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Aug. 24, 1956 [Sept. 17, 1955], No. 25972/56. Classes 40 (5) and 40 (7). The receiver for a continuous-wave (Doppler shift) radar system consists of a double superhet in which the frequency stability of the final I.F. is improved by deriving a first I.F. from a first local oscillator of limited stability and mixing the first I.F. with a signal derived from a crystal-controlled second local oscillator in such a manner that the effects of variations in the frequency of the transmitter and of the first local oscillator are substantially cancelled. The output of the first local oscillator 2, e.g. a klystron, is mixed at 5 with the received echo signals and direct leakage signals from the transmitter 1 (since they cannot be avoided) to provide a first I.F. signal consisting of an unmodulated carrier component and a Doppler shift echo component. This first I.F. signal is amplified at 6 and applied to the second mixer 11 for conversion to the final I.F. from which the Doppler shift signals are selected at 7 by a band-pass filter as disclosed in Specification 802,006, [Group, XL (b)). The local oscillation applied to the mixer 11 is obtained by mixing at 3 the output of the first local oscillator 2 with a sample of the transmitted signal thereby obtaining a signal which is subject to both the transmitter and first local oscillator frequency errors. First order stability of this signal may be obtained by an A.F.C. loop 12, 13. This signal is mixed at 9 with the output of a crystal oscillator 8 to provide the signal applied to the mixer 11. The final output of the mixer 11 then has the frequency stability of the crystal oscillator 8 as the frequency errors introduced from mixers 5 and 9 cancel.
