Title: Improvements in and relating to Electropainting.
Inventor: LEMMON TERENCE BRIAN
IPC: C08F20/62
Filed: 1966-07-20
Abstract: 1,184,549. Electro-deposition of paints. COURTAULDS Ltd. July 19, 1967 [July 20, 1966], No. 32578/66. Heading C7B. In a method of electro-painting an anode with an aqueous paint embodying a polyanionic binder which is solid at room temperature, the aqueous paint electrolyte is maintained below the coalescence temperature of the binder and allowing the paint film coating the anode to attain said coalescence temperature whilst deposition is taking place, whereupon further electro-deposition of the coated anode is inhibited. The polyionic binder used may be a copolymer containing: (a) 5-55 wt % of one or more of styrene, vinyl acetate, methyl and ethyl acrylates and methacrylates; (b) 10-60 wt % of alkyl acrylates and methacrylates in which the alkyl group contains 3-12 carbon atoms, e.g. the 2-ethylhexyl esters, the n-octyl esters, the butyl esters and the n-hexyl esters thereof; (c) 7.5-15 wt % of N-alkoxy methyl derivative of acrylamide or methacrylamide, the alkoxy group having 1-3 carbon atoms; and (d) 1-20 wt % of alkali metal, ammonium or amine salts of acrylic, methacrylic or itaconic acids. The copolymer is preferably such that a 40% aqueous solution thereof has a viscosity #10 poises at 25‹ C. The electrolyte used may contain 10% solids. The film may be heated from an auxiliary source. The molecular weight of the binder may be limited by use of a mercaptan, e. g. 2-mercaptoethanol, and the paint may contain other water-miscible solvents e. g. alcohols. Alternatively the binder may be a partial phosphate ester made by reacting (a) one or more polymers having at least one epoxy group, e. g. dihydric phenol/epichlorhydrin condensates, with (b) excess orthophosphoric acid, alone or with one or more organic acids or anhydrides, e. g. the fatty acids of drying oils, e.g. linoleic or oleic acids, the binder being rendered soluble in water by neutralizing the residual acidity of the phospate ester with an alkali, ammonia or an amine.

Title: Reheat fuel control systems
IPC: G05D16/20
Filed: 1973-07-10
Abstract: 1452487 Automatic control systems DEFENCE SECRETARY OF STATE FOR 3 July 1974 [10 July 1973] 32903/73 Heading G3R The buzz (high frequency pressure variations) in an aircraft gas turbine engine re-heat section is controlled by varying the fuel supply to the section according to the comparison between a predetermined buzz amplitude and the measured buzz. The latter is obtained from a pressure transducer in the re-heat section via a filter that passes only the pressure variations at buzz frequency. As shown, the buzz signal is obtained from the pressure transducer 30 using a band-pass filter 31, with a characteristic as Fig. 3 (not shown), halfwave rectifier 32 and first order filter 33. The output of transducer 30 is also used by a high frequency filter 36 to derive a signal dependent upon the mean pressure PJ. Circuit 37 divides the sampled buzz signal by the mean pressure to form a normalized buzz signal which is compared with pre-set levels, Fig. 4 (not shown), the comparison being used to control the re-heat fuel supply. According to whether the buzz is below or above a first level (50) the fuel flow is respectively either unchanged or reduced in increments, the aircraft throttle being over-ridden. If a second buzz level (51) is exceeded e.g. for three samples the fuel flow is reduced by a larger amount.

Title: Improvements in or relating to electronic counters
Inventor: MCAUSLAN JAMES HAY LOUDON
IPC: H03K29/00
Filed: 1953-11-30
Abstract: 766,311. Electronic counting apparatus. IMPERIAL CHEMICAL INDUSTRIES, Ltd. Nov. 29, 1954 [Nov. 30, 1953; April 7, 1954], Nos. 33155/53 and 10176/54. Class 106 (1). In counting-apparatus comprising two or more polycathode gas-filled tubes, tens transfer is effected between adjacent orders by applying the signal from the lower order zero cathode together with signals delayed relative to those applied to the second guides (i.e. the transfer electrodes next before the cathodes in the adding direction) to a first coincidence circuit and by applying signals synchronous with the second-guide signals together with a delayed zero-cathode signal to a second coincidence circuit, output signals from the two coincidence circuits being applied primarily to the first and second guides of the higher order tube respectively to add or subtract a transfer digit according to whether the lower tube is counting additively or subtractively. The limits of the delays referred to (approximately one-third of the time for one count at the maximum speed), are specified. For additive counting. negative pulses are applied to the first guides G1 of a lower order tube V1 and delayed signals are applied to the second guides G2. The latter, further delayed by a circuit R1, C1, X1, or a monostable trigger pair, are applied to the first (pentode) coincidence gate V3 to which the zero cathode of the tube V1 is directly connected. As the counting-tube discharge reaches the zero cathode, coincidence occurs and the output of the pentode V3 is passed through a shaping stage V2 and applied to the first guides G3 of the next counting tube V4, a corresponding delayed signal being applied to the second guides. In subtractive counting, negative pulses are applied to the second guides G2 of the tube V1 and delayed signals to the first guides G1. The zero cathode is connected through a delay circuit R2, C2 to the second pentode coincidence gate V6, to which are also applied positive signals, synchronized with the negative second-guide pulses, from a source 30 (e.g. the other anode of a shaping tube feeding-in the negative pulses to be counted). In this case, coincidence occurs as the counting-tube discharge arrives on the adjacent second guide after leaving the zero cathode. The output of the pentode V6 is passed through a shaping stage V5 and applied to the second guides G4 of the next counting tube V4. The same signal, delayed, is applied to the first guides G3. By reversing all the potentials, the counting tubes may be operated as polyanode tubes. The counter may be incorporated in apparatus for determining the position of a shaft, e.g. in weighing-apparatus. Specifications 757,105, 757,922, [both in Group XL (b)], and 771,057 are referred to.

Fissile material (e.g. UO 2 ) is circulated through a reactor 1 in suspension in a carrier liquid such as H 2 O or D 2 O, the suspension being diluted outside the reactor to reduce the viscosity and thereby assist circulation. On leaving the reactor the fuel suspension flows through a heat exchanger 14 and then into a conduit 16 where more carrier liquid is added. The fuel suspension is then pumped through a vertical pipe 6 by helium or carbon dioxide, supplied by a pump 7, and through a hydrocyclone thickener 12 to return the concentrated suspension to the reactor. D 2  and H 2  formed by radiation are catalytically oxidized at 9a and the resultant water returned to 8. Gaseous fission products are removed at 10 and fission products in solution are removed from the carrier liquid at 18. Some of the carrier liquid may be added through a valve 20 to the flow through the heat exchanger 14. Heavy water 2 is pumped through a heat exchanger 5. The reactor is surrounded by a bismuth reflector 3. In a modification, Fig. 2 (not shown), solid moderator particles of BeO are also suspended in the carrier liquid and the suspension is kept mixed in the reactor by a vibrostirrer.
