Patent GB-822146-A (GB)
Title: Fertilisers
Inventor: HARRIS FREDERICK JOHN
IPC: C05B19/00
Filed: 1955-09-21
Abstract: Granular fertilizers are surface coated with an anticorrosive additive comprising a water-soluble condensed phosphate other than a cyclic trimeta- or tetrametaphosphate and which is derived from acids of the formula H4P2O7, H5-P3O10 and (HPO3) x, the coating being caused to adhere to the granules by means of an oil or other similar viscous material, e.g. aqueous solutions of gelatin, or sodium aliginate.  Suitable additives are derived from an acid of formula H4P2O7 by replacing any proportion of the hydrogen ions with alkali metal or ammonium ions.  The additives, which should be present in the proportion of at least 0,25% by weight of the fertilizer, may be applied to the granules in various ways, for example a hydrocarbon oil of viscosity 30,000 Redwood No. 2 seconds at 70 DEG F. and 179 Redwood No. 2 seconds at 200 DEG F. is heated to 180 DEG F. and sprayed on to the granules, whereafter tetra sodium pyrophosphate is added as a dust.  Using this process, a suitable proportion of oil is from 0,1% to 0,5% by weight of the fertilizer.  Alternatively, the tetra sodium pyrophosphate may be sprayed with a similar oil, and this material subsequently mixed with the fertilizer granules. Specification 822,145 is referrred to.

Title: Dispensing frozen foodstuffs
IPC: A23G9/32
Filed: 1937-10-05
Abstract: 503,421. Coating surfaces; coating- compositions. CRAEMER, R. A. Oct. 5, 1937, No. 26998. [Class 95] [Also in Groups XVII and VIII] Relates to a method of dispensing frozen edible products such as ice-cream from a container with the minimum of loss due to adhesion to the container wall. The containers may be paper, cardboard, or parchment cartons, metallic containers or moulds, collapsable paper, &c. containers, or packages formed by ordinary wrapping or by helical winding, such for example as are described in U.S.A. Specification 1,932,169. In order to prevent adhesion, a layer of substance which is liquid at the temperature at which the foodstuff will be removed from the container is applied over the entire surface of the container between it and the contents. The substance may comprise an aqueous solution of a sugar or sugars, ethyl alcohol, glycol or glycerine or any of these. A salt such as common salt may be added to depress the freezing point further. The substance. may be applied by brushing or spraying, and the process may be repeated if necessary. The freezing point should be sufficiently low, e.g. below 15‹ F., and the viscosity should be sufficiently high to cause proper adherence to the container. Gelatine or gum arabic may be added to aid this effect. The substance preferably shows a preferential adhesion to the material of the container, as compared to the contents, and may penetrate to some extent into the material of the container. The coating may be of such a composition as to congeal at storage temperature and to become liquid at dispensing temperature. The container may be pre-coated with paraffin &c. In the case of such water-repellent surfaces it is preferable to use oil as the coating. Glycerine or vegetable oils such as walnut, sunflower or poppyseed oil, and refined mineral oils such as "White Oils," "Crystal oils," and the substances known under the Registered Trade Marks "Lujol," "Oronite" and " Marcol " and by the trade names of Amaline and Wyrol are mentioned.

Title: Preparation of diesters of succinic acid
IPC: C07C69/40
Filed: 1949-10-20
Abstract: Di-esters of succinic acid are prepared by reacting succinonitrile with an alcohol employing between 2 and about 4 molecules of the alcohol for each molecule of the nitrile, the reaction being carried out under the influence of heat in presence of water and a substance which combines with ammonia to form a salt, this substance being in a quantity equal to 2 to 3 times the stoichiometrical equivalent of the ammonia theoretically available in the process.  The alcohol may be aliphatic, aromatic or heterocyclic and may be substituted by iodine, bromine, chlorine or nitro groups; specified alcohols are butyl, sec.-butyl, amyl, benzyl and furfuryl alcohols.  The ammonia-binding agent may be benzenesulphonic acid, ethyl hydrogen sulphate or diethyl sulphate and is preferably sulphuric acid. Ethers formed as a by-product are desirably removed by distillation during the reaction. Examples (5) are given of the preparation of diethyl and dimethyl succinates; some of the monoethyl ester of succinic acid is formed as a by-product.

Title: Improvements relating to automatic telecommunication switching systems
Inventor: WARMAN BLOOMFIELD JAMES
IPC: H04Q3/00
Filed: 1964-07-02
Abstract: 1,080,622. Automatic exchange systems. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. June 22, 1965 [July 2, 1964], No. 27368/64. Heading H4K. Permanent calling condition, resulting in the disconnection of holding earth from the P-wire over primary switch PS, causes the release of relay KB but not of KA so that a gate PG allows scanning pulses on gate GX<SP>1</SP> to open gate GY<SP>1</SP> to produce signal L2. The line circuit exhibits calling condition on resistor R4 to prime gate CG so that scanning pulses on gate GX open gate GY to produce signal L1. Earth on the P-wire operates KA and KB, cut-off relay KK following. Release is effected with negative battery on the P-wire to drop both KA and KB with KK following. Permanent calling condition with KB back but KA held up, leaves KK in a circuit with insufficient energizing current. So long as scanning finds signals L1 and L2 to indicate permanent calling condition, no action is taken, but as soon as the line goes on-hook to remove signal L1 the line circuit is connected up for the return of negative battery over the P-wire to release KA. The relays employed are preferably reed relays and the circuit is preferably constructed in modular form. Where the system is such that, with resistive negative battery applied to the P-wire to release the line circuit, a following call causes the concurrent connection of earth to the P-wire before KA has released, a Zener diode in the path between KA and its negative battery supply produces a drop of a few volts sufficient to balance the voltage drop across the diode MR1 which shunts KB. Relay KA is thereby allowed to release despite the following call.

Patent GB-1471281-A (GB)
Title: Control circuit camera
IPC: G03B7/00
Filed: 1974-06-24
Abstract: 1471281 Cameras HONEYWELL Inc 24 June 1974 [28 June 1973] 27886/74 Heading G2A A camera has a light integrator 142, a voltage reference 158, means 152, 156 for comparing the outputs of the integrator and voltage reference, an electronic flash unit 114, and a binary logic control circuit which samples the output of the comparator during the early part of the shutter opening period and if the light level is low actuates a flash and closes the shutter and if the light level is high controls shutter time in response to a signal from the comparator. Preferably the control circuit also controls a lens focusing motor 50. As shown, on depressing the shutter release, a switch 84 changes over to set a flip-flop 183 which turns on a transistor 168, top of Fig. 3B, to energize motor 50 to rotate anticlockwise and focus the lens (60) Fig. 2 (not shown). When the lens is correctly focused, a circuit 126 resets flip-flop 183 which (a) deenergizes the motor, (b) turns off a transistor 172, bottom of Fig. 3B, to de-energize a solenoid 40 whereby a shutter-diaphragm, Fig. 1 (not shown) starts to open (c) turns off a transistor 144, top Fig. 3A, whereby a silicon photodiode 142 starts to integrate scene illumination, the integrated signal being compared with high and low reference voltages 158 by comparators 152 and 156 respectively. A switch 204, bottom of Fig. 3A, is closed by the shutter blades when they reach f/11 and if the lower reference voltage 156 has not been reached at this point flip-flop 191 remains set to record that flash is necessary. Then when a switch 78, bottom of 3B, whose position is dependent on the focus setting is actuated by the shutter a gate 208 connected to switch 78 and flip-flop 191 is charged over to turn on an SCR 126 whereby a flash tube 114 discharges. Thus the shutter aperture at the time of firing is determined by the focus setting. Gate 209 also resets a flip-flop 195 to de-energize a solenoid 46 to close the shutter. If the illumination is high, flip-flop 191 is reset and the flash is not fired. Instead, the shutter opens until the higher reference voltage 152 is reached, whereupon flipflop 195 is reset to de-energize solenoid 46 to close the shutter. When the shutter has closed and switch 84 been returned, a switch 96 is closed to energize motor 50 to rotate clockwise and cock the shutter and advance the film. The flash capacitor 112 also charges up, completion being indicated by lamp 122. For the circuit to work a switch 90, coupled for instance to a retractable viewfinder, must be closed, as must a switch 92 coupled to the film cartridge compartment door. The automatic focusing system may be replaced by a manual one, in which case circuit elements 216, 218 reset flip-flop 183 as soon as the release switch 84 is charged over.
