Title: Improved method of electrolytically depositing iron
IPC: C25C1/06
Filed: 1931-05-21
Abstract: 378,962. Electrodeposition of iron. KELSEN, E., 19, Menzelgasse, Vienna, and AUSNIT, E., 3, Rue Clemenceau, Bucharest. .May 21, 1931, No. 15083. [Class 41.] In the deposition of iron sheets a low initial current density, e.g. 2 amps. per sq. dcm., is employed and is raised gradually or by stages to the working value, which may be 5 amps. per sq. dcm., and thereafter maintained constant. The rate of increase should be such as to render the hydrogen absorption uniform throughout the deposit and thereby to prevent scaling due to internal strains. The period during which increase takes place should be not more than 60 minutes, say 30-45 minutes. A hot solution of an iron salt is used as electrolyte ; if the temperature varies, the rate of increase of current density should be modified. A suitable electrolyte contains 90 gms. iron, 49 gms. sodium, 12 gms. barium, and 202 gms. chlorine per litre, the acidity being kept at pH = 3À0 ; it is circulated at 90 C.

Inventor: WHITE BARRINGTON JOHN LEON ARD
IPC: H02P7/20
Filed: 1966-04-05
Abstract: 1,131,352. Control of motors. CLEVEDON ELECTRONICS Ltd. 4 July, 1967 [5 April, 1966], No. 15128/66. Heading H2J. [Also in Division H1] A motor 1 driving dispensing mechanism 4 is started by closing contacts 9 to energize coil 10 for overcoming the effect of magnet 8 which is positioned on the periphery of a motor-driven drum 7. Contacts 6 of a reed relay 5 are thereby closed in series with the motor. The contacts 9 are released when the magnet 8 has moved away from the neighbourhood of the contacts 6. The motor then rotates shaft 2 through a complete revolution to bring the magnet 8 back to its original position, where it will again open the contacts 6 and stop the rotation of the motor. In another arrangement, the device for opening the motor circuit includes a stationary magnet and a magnetic screen which is moved between the magnet and the contacts of the reed relay when the shaft reaches a predetermined angular position.

Title: Apparatus for the detection and removal of selected foreign matter from a material
IPC: B07C5/342
Filed: 1970-03-31
Abstract: 1293208 Detecting yolk in albumen photoelectrically DIAMOND INTERNATIONAL CORP 31 March 1970 [7 Oct 1969] 15172/70 Heading G1A Apparatus for removing yolk contaminated albumen from a stream of uncontaminated albumen flowing over a darkened area of a chute comprises a pair of photo-sensitive devices one responsive to yellow reflected light to cause operation of a flow diverting mechanism. The albumen flows down chute 1 and is illuminated at AB by light source 2. The reflected light passes through lens 4 to beam splitting mirror or prism 5 so that half the light passes through rectangular slit 8 and green filter 12 to fall on photo-multiplier 14 and the other half passes through slit 6 and blue filter 11 to fall on photo-multiplier 13. The photomultipliers are differentially connected to amplifier 18 whose output under balanced conditions is zero. To balance the light falling on the photo-multipliers adjustable diaphragms or polaroid discs 15, 16 may be used or alternatively the dynode voltage may be varied by potentiometer 17. To avoid direct reflection from the surface of the albumen polarizing discs 28, 29, having axes at right angles, are used. In operation, the presence of yolk causes extra light to be transmitted through green filter 12 so that an unbalance appears at the input to amplifier 18 to provide an output which energizes electromagnet 22 to operate air cylinder 23 and move chute 24 into alignment with reject channel 27. The outputs of the photo-multipliers can be displayed on meters 19, 20, 21. The presence of shell or chalaza in the stream affects the quantity of light reflected to both photo-multipliers and thus does not disturb the balanced condition. In a modification the contaminated albumen is sucked out of chute 1 by a gear pump which is driven in response to the unbalance signal.

Title: Improvements in or relating to dehydration by azeotropic distillation
IPC: B01D3/36
Filed: 1938-05-21
Abstract: 515,025. Distilling alcohols &c. USINES DE MELLE. May 21, 1938, No. 15203. Convention date,-May 25,1937. [Class 32] In the dehydration of organic liquids, e.g., alcohols, chlorhydrins, amines, ketones, by azeotropic distillation, the condensed ternary mixture of minimum boiling-point is decanted while at a temperature approximately equal to the temperature of the still-head, the aqueous layer formed is withdrawn and cooled, and is then again decanted to separate the entraining agent. The alcohol to be dehydrated is led from a vat 2 into a distilling column 1 provided, below a number of bubbling plates b of usual, construction, with a plate d traversed by vapour pipes d<1> and an overflow pipe e so that liquid accumulates on the plate d to such depth that decantation can take place. Vapours of .the ternary azeotropic mixture pass off at the top of the column to a condenser and the condensate is returned through line 3<1> to the top plates where it is freed from head impurities. The condensate then collects on the plate d where it separates into two layers, the bottom layer rich in entrainer being returned through the overflow e to the lower part of the column, while the aqueous layer is led off through a valved pipe h and cooler 4 to a decanter 5 and separated into a top layer of entraining agent (which is returned to the column through a line 6) and an aqueous layer practically free from entrainer (which is concentrated by distillation in a column 7, the concentrated alcohol being returned through a pipe 9). Modified constructions of the first decantation chamber are shown (a) in Fig. 3, to allow the bottom layer to be withdrawn and the top layer to be passed down the column ; (b) in Fig. 4, to allow both layers to be drawn off simultaneously. The application of the invention to the direct dehydration of fermented worts as described in Specification 350,473 is also described. In examples: (1) the top layer comprising 54 per cent. water, 36.5 per cent. alcohol, 9.5 per cent. benzene, is cooled and decanted whereupon an aqueous layer containing 59.7 per cent. water and 40 per cent. alcohol and only 0.3 per cent. benzene is obtained ; (2) in the dehydration of monobutylamine with cyclohexane as entrainer the lower layer comprising 39.4 per cent. monobutylamine, 25.8 per cent. cyclohexane, and 34.8 per cent. water, after cooling and decantation yields an aqueous layer comprising 14.8 per cent. monobutyamine, 84.7 per cent. water and 0.5 per cent. cyclohexane. Specification 220,606, [Class 32], is referred to.

Abstract: 1,178,489. Antibiotic tenebrimycin. ELI LILLY & CO. 4 April, 1967, No. 15349/67. Heading C2A. The invention relates to an antibacterial antibiotic tenebrimycin complex, its components tenebrimycins, I, I<SP>1</SP>, II, III, IV, V and VI, mixtures thereof, and acid addition salts thereof. Tenebrimycin complex is produced by cultivating Streptomyces tenebrarius ATCC 17920 or ATCC 17921 or a tenebrimycin-producing mutant thereof, in a culture medium containing assimilable sources of carbon, nitrogen and inorganic salts under submerged aerobic conditions, preferably in the absence of visible light. Tenebrimycin is isolated from the clarified fermentation broth by adjusting to pH 5À5 and passing down a column of Amberlite IRC.50 (cation exchange resin) on the ammonium cycle. After elution with dilute acid, the eluate is concentrated and the pH adjusted to 11, poured into acetone, clarified and the sulphate precipitated by adding H 2 SO 4  to pH 3À5. The precipitate is dissolved in water and treated with an anion exchange resin to recover the tenebrimycin in the form of the base. The complex is fractionated by passing an aqueous solution of tenebrimycin sulphate down a column of Amberlite IRC 50 on the NH 4  cycle and eluting with 0À1 N, NH 4 OH and collecting fractions containing tenebrimycins I, I<SP>1</SP>, II, then III, then IV and finally V by eluting with 0À3 N, NH 4 OH. Further purification is obtained by first forming the helianthate of the component, decomposing the helianthate with aqueous H 2 SO 4  of pH 2À0, followed by treatment with (a) an anion-exchange resin on the OH- cycle and then (b) a retardation exchange resin.
