Title: Improvements in or relating to methods for the production of anhydrous monocalcium phosphate and in products containing the same
IPC: C01B25/32
Filed: 1938-08-30
Abstract: 518,738. Baking-powders. STEVENS, A. H., (Victor Chemical Works). Aug. 30, 1938, No. 25392. [Class 49] [Also in Group III] Anhydrous monocalcium phosphate, which may be made as described in Specification 518,737 is heated at a temperature above 140‹C. but below that at which pyrophosphate is formed for a sufficient time to produce a thin vitreous coating on the particles. The primary reaction rate with-sodium bicarbonate is thereby reduced and a product suitable as an ingredient of baking-powders and selfraising flours is obtained. Alternatively hydrated monocalcium phosphate may be dehydrated at 100-180‹C. and the heating then continued at 180-220‹C. Temperatures above 230‹C. should be avoided. In the case of the anhydrous salt the heating may be effected by passing the salt rapidly through a flame. The presence of impurities characteristic of phosphoric acid and particularly of alkali metals is desirable.
Patent GB-606812-A (GB)
Title: Improvements in or relating to potential-dividing electric circuits
IPC: H03G3/20
Filed: 1945-10-01
Abstract: 606,812. Impedance networks. COURSEY, P. R., SNELL, L. J., STEATITE & PORCELAIN PRODUCTS, Ltd., and DUBILIER CONDENSER CO. (1925), Ltd. Oct. 1, 1945, No. 25403. [Class 40 (viii)] [Also in Group XL (c)] A condenser with a voltage-sensitive ceramic dielectric forms part of a network which may be used for automatic tone-control, or in a negative-feedback amplifier, or for maintaining a constant output voltage. The dielectric may comprise 95 per cent of barium titanate with 5 per cent of strontium titanate, or some other mixture of titanates of the alkaline earths described in Specifications 574,577 and 601,109, [both in Group XXXVI], so that the capacity varies both with the amplitude of the applied voltage and with its frequency. A D.C. biassing potential may be applied to the ceramic condenser. In a tone-control network, Fig. 6, the voltage-sensitive condenser 1 and resistance 2 are arranged as shown, and with a suitably-chosen ceramic the amplification rises with frequency (and more rapidly for weak than for strong signals) up to a saturation maximum, Fig. 9 (not shown). The resistance 2 and ceramic condenser 1 may be interchanged to form a voltage-stabilizer, Fig. 4 (not shown), the output voltage being relatively constant during changes of input voltage. A tonecontrol device in which lower frequencies are amplified more than higher frequencies, especially at low signal-strengths, is formed, Figs. 7, 8 (not shown), by interchanging the ceramic condenser 1 and resistance 2, Fig. 6, and adding a resistance in series with the former and an ordinary condenser in series with the latter. In an amplifier with negative feedback, Fig. 11, the feedback may be tapped-off above the ceramic condenser 22 and below the resistance-capacity shunt combination 23, 24, so that the amplification and its frequency characteristic both depend on the strength of the applied signal. One pair of opposite arms of a bridge, Fig. 12, may comprise resistors and condensers in shunt, while the other pair comprise ceramic condensers; and such a bridge may be embodied in a circuit with negative feedback, Fig. 13 (not shown).

Abstract: 1,192,235. Storage systems. KAISER INDUSTRIES CORP. 6 June, 1967 [25 July, 1966], No. 26119/67. Heading B8E. A system for storing and shipping cargo between remote points comprises containers 10 for the cargo, storage compartments 16 adapted to receive the containers, a gantry crane 20 for servicing the compartments 16, conveyer means 25 for moving the containers between the crane 20 and a cantilever crane 27, transport means such as a ship 26 for moving the containers between remote points, the ship being serviced by the crane 27, and a computer 23 for controlling the cranes 20 and 27. Containers are carried to or from the system by a train or a road vehicle through passageways 13 above which are the compartments 16 arranged in blocks 14, a crane 20 being provided for each pair of blocks 14. A signal is transmitted from the crane 20 to the computer 23, the signal representing the location of a container, and the latter's identification and contents. The signal may give confirmation that the container has been stored in a specific compartment according to a command from the computer. Each container may be identified by a magnetic plate or a punched card read by means associated with the crane 20 and transmitted to the computer. The latter may retrieve the information about a container from its memory and transmit a signal to the crane 20 to retrieve the container and deposit it on the conveyer means. When the ship 26 is to be loaded identity of the cargo required is fed to the computer which then controls the cranes 20 and 27, the crane 27 transmitting a signal to the computer identifying the location of the containers in the ship. The computer may select the location of the containers in the ship and command the crane 27 according- ly. The computer memory may then be removed from the computer and sent with the cargo so that the memory may be used in a similar system at the destination of the ship to unload the latter. Alternatively, a single computer may control the other system via transcontinental telephone lines. The unloading process is the reverse of the loading process although the containers may be loaded directly from the conveyer means 25 on to the train or road vehicle. The computer may inventory cargo, print bills of lading and other documents, balance the load on ships and measure the time limits for holding refrigerated or perishable cargo. The containers may be enclosed on all six sides, may have only a floor and side walls or may only be a pallet. The conveyer means 25 may be a belt or roller conveyer or electric cars running on rails. Instead of the ship 26 the transport means may be a train, a road vehicle or an aircraft.
