Title: A process of separating and collecting organic acids and bases from beetroot molasses
Filed: 1924-07-05
Abstract: 233,196. Takayama, Y. July 5, 1924. Alkalies and carbon compounds, obtaining; diaphragms; electrolytes, circulating. - Beetroot molasses, or the residue after fermentation of the same and distillation of the alcohol, is electrolyzed so that glutamic, glutimic, and succinic acids or salts thereof, are obtained at the anode and betaine and caustic potash and soda at the cathode. The molasses or fermentation residue may be run through a pipe 9 into a compartment between two diaphragms 4, 4<1> of parchment paper &c. From the uppermost compartment containing the cathode the solution of the bases is run off continuously through a pipe 10. The anode products are washed away through a pipe 8 by a stream of water from a pipe 7. The diaphragms are inclined so that gases collect at one end and are removed by pipes 11, 12. A soluble anode of zinc, iron, aluminium, &c. may be used. The anolyte removed may be treated with an alkali to precipitate iron, or with hydrogen sulphide to precipitate zinc. Heating with a mineral acid then converts the glutimic acid to glutamic acid, which is then isolated as the hydrochloride, calcum salt, or free acid. Succinic acid may be crystallized from the mother liquor . The glutimic acid may, alternatively, be converted into glutamic acid either before removal of the anode metal or, when treating fermentation residues, before electrolysis. Or the glutimic acid and glutamic acid may both be converted into calcium salts, precipitated by alcohol, and separated by treatment with water. Caustic potash and soda in the cathode product are converted into chlorides, sulphates or carbonates and crystallized out after concentration; from the mother liquor, betaine is extracted by means of alcohol. Alternatively, the whole cathode liquid is concentrated and betaine is converted by heat into trimethylamine and distilled.

Title: Improvements in electric relaxation oscillators
IPC: H03K4/86
Filed: 1937-06-11
Abstract: 479,732. Valve generating circuits. RADIOAKT.-GES. D. S. LOEWE. June 11, 1937, No. 16244. Convention date, June 20, 1936. [Class 40 (v)] The frequency of a relaxation oscillator is adjusted without varying the amplitude by variation of the resistance through which the condenser is charged. As shown, a potentiometer comprising resistances 7, 8, 5 is connected across the supply source 1. The condenser 3 is charged from a tapping on the resistance 7 through a resistance 2, the charging-current also flowing through the resistance 5. A further resistance 9 connects the tapping to the positive side of the source 1..The condenser 3 discharges through a gas-filled discharge tube 4 and a low resistance 6, the grid of the tube being biassed by the voltage across the resistance 5. Frequency is adjusted by moving the tapping on the resistance 7, and the connections are such that the current through the resistance 5 and therefore the bias on the grid of the tube 4 are substantially unaffected by the frequency adjustment. The oscillations may be fed to an amplifier 13 through a condenser 12 and a potential divider 15, 16 which applies only a small fraction of the available voltage to the grid. The fine frequency adjustment provided by the resistance 7 may be supplemented by a coarse adjustment in steps, by providing a number of condensers 3 and a number of resistances 9 with a multiple-contact switch for selecting one of each, Fig. 2 (not slown).

Title: Improvements in and relating to coating materials
Inventor: STURM ROBERT HEINRICH
IPC: H01B1/00
Filed: 1946-05-29
Abstract: For the production of a continuous metal or alloy coating on an insulating base, a powdered metal or alloy having a melting point in the range of 44 DEG -250 DEG C. is applied to the base by means of a binding, adhesive, suspension, or fluxing medium, and is thereafter heated at least to its melting point.  After grinding, the powder may be screened through a 250 or 300 mesh sieve, and treated to remove any oxide coating.  Also, it may be mixed with fine grade particles of a higher melting point metal or alloy, such as copper, silver or brass, free from oxide films, all the metallic powders preferably being of flat or platelike particles. The binding or suspension medium may be volatile, or it may comprise a plastic the setting or polymerization temperature of which is at least as high as the melting point of the metal or alloy.  The application may be effected by spraying, printing, dipping, roller coating, spreading, tumbling or brushing.  The heat may be applied by a flame gun or a gas brush, or, in the case of porous bases, impregnation under vacuum may be followed by heat and pressure in an inert gas.  The coating may then be electroplated.

Title: Electroslag refining
IPC: B22D23/10
Filed: 1972-04-11
Abstract: 1380467 Electroslag refining processes BRITISH STEEL CORP 10 April 1973 [11 April 1972] 16677/72 Heading B3F [Also in Divisions G3 and H5] In an electroslag refining process in which one or more electrodes depend into a vessel 1 having an upper reservoir portion 2 and a lower mould portion 3 having a cross-sectional area less than that of the electrode(s), the level of the molten metal pool 18 is maintained at or adjacent the interface of the reservoir and mould portions of the vessel. This is achieved by detecting the formation within the reservoir portion 2 of a pool of molten metal having a surface area equal to or greater than that of the electrode(s) and causing relative movement between the vessel 1 and the ingot 20 formed. When the surface of the molten metal pool is within the mould portion 3, further melting of the electrode 4 results in a decrease in the distance between the end of the electrode and the said surface due to the difference in the cross-sectional areas of the electrode and mould portion 3. As the distance decreases a corresponding increase in current will occur if the voltage is maintained constant. When the surface of the pool 18 is within the reservoir portion 2, further melting of the electrode results in an increase in the said distance and thus a decrease in current. Such reversals in the direction of current change are detected by a device 17 which activates a motor 13 to move the vessel 1 upwardly to lower the level of the pool 18 to a position at or adjacent the interface between the reservoir and mould portions. Alternatively, the motor 13 may be activated when the current reaches a maximum value or when a change in the rate of current variation is detected. In a modification the voltage is maintained constant and variations in the voltage are monitored. At start-up, the vessel 1 rests on a base-plate 5 having a member 7 which extends into the lower end of the mould cavity and is made of a material weldably compatible with the metal -to be refined. The annular space between the wall of the mould cavity and the member 7 is filled with crushed slag 8. A ring 9 of asbestos or steel is placed above the slag 8. The base-plate 5 rests on load cells 6 which monitor the weight of the ingot 20. The height of the ingot and the position of the vessel 1 may also be measured. The vessel 1 may be provided with more than one mould cavity so that a plurality of ingots may be formed simultaneously from a single electrode.

Abstract: 1,262,527. Projectiles; firearm barrels. COLT'S Inc. 31 March, 1969, No. 16733/69. Headings F3A and F3C. A projectile for squeezebore firearms comprises a plurality of sub-projectiles 2, 3, 4 and 5 with annular cavities 14, 19 and 20 between each of the projectiles, each of the cavities containing a readily deformable material, the resistance to compression of which creates a reaction force which separates the sub-projectiles as the flanges 15 are deformed inwardly owing to passage of the projectile through the squeezebore of the firearm. The sub-projectiles are bonded together by P.T.F.E. or a lead alloy which acts as a lubricant after separation. The points of the projectiles may be flame hardened. The deformable material in cavity 14 is constituted by air and is supplemented by propellant gases entering through a passage 16 which is nipped shut in the squeezebore. Wax fills the cavity 19, and the cavity 20 contains air and a propellant charge 21. Compression of the air in cavity 20 causes ignition of the propellant charge, thus facilitating separation. In another embodiment (Fig. 6, not shown), each of the sub-projectiles includes a cylindrical flange (30) and a hardened core (34). The firearm comprises a rifled portion 17 leading on to tapered smooth and cylindrical portions.
