Title: Improvements in or relating to cathode ray tube apparatus for transmitting images ofan object to a distance
IPC: H01J31/30
Filed: 1936-05-18
Abstract: 478,499. Cathode-ray tubes. ZEITLINE, V., ZEITLINE, A., and KLIATCHKO, V. May 18, 1936, No. 30401 /37. Convention date, May 18, 1935. Divided out of 477,326. [Class 39 (i)] Cathode-ray tube apparatus for transmitting images of an object to a distance comprises an optical system L projecting an image of the object upon a photo-electric screen P arranged in an enclosing envelope T, whereby the consequent photo-emission produces an electron image corresponding to the optical image, a charge storage electrode comprising fluorescent material F disposed in the envelope and designed to accumulate electrical charges corresponding to the electron image, which electrode is scanned by an electron beam R which neutralizes the charges and produces picture signal currents. A visible image may be produced on the layer F which facilitates focusing of the electron image. The charge storage electrode comprises an insulating plate J carrying on one side the layer F and on the other a conductive plate M. The signal currents may be derived either capacitatively from the plate M or from secondary electrons collected by electrode O. The focusing of the electron image may be magnetic, by the coil H, or electrostatic, by electrode O, or both. An accelerating grid Ap is provided. In a modification, focusing is obviated by placing the photo-electric screen and the charge storage electrode close together. In this case the plate M is omitted and the screen P is placed adjacent the plate J which is made so thin that the charges accumulated on the side of plate J facing P are transmitted by conduction to the layer F, the transverse conductivity remaining sufficiently high to preserve the charge image. The plate J may also be of semi-conductive material. Specification 442,666 is referred to.

Abstract: 1,194,365. Antibiotic AV290. AMERICAN CYANAMID CO. 30 June, 1967 [29 July, 1966], No. 30424/67. Heading C2A. The invention relates to an antibacterial antibiotic, antibiotic AV290, its salts and hydrolysis product having the following properties: AV290 base and sulphate are soluble in water and dimethylsulphoxide, moderately soluble in methanol, insoluble in other common organic solvents. Antibiotic AV290 is produced by cultivating Streptomyces candidus NRRL 3218, or an antibiotic AV290 producing mutant thereof, in an aqueous nutrient medium containing assimilable sources of carbon, nitrogen and inorganic salts under submerged aerobic conditions. The fermentation broth is clarified at pH 6À0, treated with activated carbon, washed and eluted with 40% aqueous acetone of pH 2À0. After concentrating, Ba(OH) 2  is added to pH 5À5, the precipitated BaSO 4  removed and the liquid is treated with acidified alumina of pH 3À0. 50% aqueous methanol is used for elution, followed by addition of Ba(OH) 2  to pH 6À3 to precipitate excess SO 4  ions and crude AV290 is recovered. Further purification is by adsorption on Amberlite 1RC-50 (Trade Mark) or CM Sephadex C-25 (Trade Mark) and elution with dilute H 2 SO 4  or aqueous NaCl. Antibiotic AV290 sulphate is converted to the base by treatment with a mixture of Amberlite 1R45 (OH-) and Amberlite 1R20 (H+). The hydrolysis product is obtained by boiling AV290 base with aqueous HCl. A therapeutic composition for administration to humans and animals comprises antibiotic AV290, a salt thereof, or the acid hydrolysis product and a carrier, e.g. for topical or parenteral use.

Title: Heterogeneous selective membranes and a process for the preparation thereof
IPC: C08J5/22
Filed: 1964-08-04
Abstract: A selective membrane, suitable for the potentiometric determination of the activity of ions present in solution, for ion-exchange or for the separation of ions, comprises a substantially water-insoluble active material of a particle size within the range of 1 to 50 microns and suitable for pearl-type electrical conduction and development of chemical equilibria at the two surfaces of the membrane, dispersed in a silicone rubber in such an amount that the particles are sufficiently in contact with each other for pearl-type electrical conduction to occur. The membrane can be made by dispersing the particles in a rubber-forming siloxane, and curing the resulting dispersion, as by adding curing agents and catalysts and curing at ambient or elevated temperature, to obtain said membrane. The active material may be an inorganic precipitate, a metal chelate, an ion exchange resin or a molecular sieve.  In examples, membranes are made by cold-curing a mixture of an active material, a dimethylpolysiloxane, dibutyltindilaurate and hexaethoxydisiloxane, between two plastic sheets, using respectively (1) AgI and (2) BaSO4 as the active materials.

Abstract: 392,200. Type-printing telegraphy. CREED & CO., Ltd., Telegraph House, Croydon.-(Teletype Corporation ; 1400, Wrightwood Avenue, Chicago, U.S.A.) Nov. 12, 1931, No. 31345. [Class 40 (iii).] In a page-printing telegraph, the printing carriage 45 comprising a series of permutation discs 10 .. 14, latch members 20, and a rotatable type carrier 65, is movable in relation to a stationary platen 83. In all positions of the printing carriage, the permutation discs 10 .. 14 are in operative relation to a relatively fixed series of pivoted vanes 1 .. 5 controlled by the code signals. The latch members 20 are pressed towards the discs 10 .. 14 by springs 25 but are normally held out of engagement therewith by a plate 28, the position of which is controlled by a cam 31 on a sleeve 32 slidably keyed on the main shaft 33, which rotates once for each character to be printed. The plate 28 also carries a stop 28<1> which normally engages a type-wheel stop-arm 49 adapted to engage a selected latch member 20. The stop-arm 49 and type-carrier 65 are carried by a shaft 48 driven through friction clutch plates 51 by a worm wheel 53 engaging a worm 54 slidably keyed to the continuously driven shaft 55. The type-carrier 65 supports a series of type-carrying members 68 normally kept in a vertical position by individual springs 69. Each member 68 has a centering and striking projection 71 which,- in the printing position, is engaged by the V- shaped end of a striking lever 73, Figs. 1 and 5, the lower end of which is periodically engaged by a printing bail 76 on the actuating rod 78 driven from the printer main shaft. The printer carriage 45 is supported by rollers 58, Figs. 2 and 4, on the shaft 55 and letter spacing is effected by a worm 34, Figs. 2 and 3, on the sleeve 32, the worm engaging a relatively fixed rack 37, which can be rocked out of the way for carriage return. Additional controls such as case shift, line spacing, carriage return, &c. are effected by notched bars 86, Fig. 2, directly engaging the vanes 1 .. 5. Operation. At the commencement of each cycle, the shaft 33 is stationary and the high part of cam 31 causes the plate 28 to arrest the type-wheel stop arm 49 and move the latch members 20 so that the permutation discs 10 .. 14 can be set by the vanes 1 .. 5. When the last disc has been set the shaft 33 rotates once and the cam 31 permits the plate 28 (1) to release the latch members 20 so that one falls into a row of notches, and (2) by withdrawing pin 28<1> to release the type-wheel shaft 48 which rotates until arm 49 engages the selected latch member 20, thus arresting the shaft 48. The type-carrying member 68 is then operated by the printing bail 76 through the striking lever 73.
Patent GB-417085-A (GB)
Title: Improvements relating to grindstones and processes of treating same
IPC: B24D5/00
Filed: 1933-11-11
Abstract: 417,085. Treating sandstone grindstones. McGILL, W. H., 21, Oxford Street, Winchester, Massachusetts, U.S.A. Nov. 11, 1933, No. 31510. [Class 60.] Grindstones of natural sandstone, such as are used for making wood pulp, are impregnated through at least the service volume with a waterproof binder which retains its binding property at the operating temperature of the stone, disintegration of the stone during grinding by moisture and heat being therefore avoided. In one impregnation process, the stone 2 is baked to drive out moisture and the ends of the central bore are closed by plates 4 and gaskets 8. The stone is then placed in a pressure tank 3, the central bore communicating with the external atmosphere by a tube 15 connected to a vent 13 in one of the plates 4. The end faces of the stone are preferably given a sizing coat 10 of a material impervious to the binding medium. The liquid binding medium is introduced into the tank and air under pressure is admitted through a pipe 20. A vacuum may be created in the tank before the liquid is introduced. The liquid is forced by the pressure radially inwards through the stone from the periphery to the central bore. In a typical case an initial pressure of twenty-five pounds to the square inch is applied and is increased by ten pounds at the end of half an hour and to fifty pounds at the end of an hour, this final pressure being maintained until liquid is delivered through the pipe 15. Preferably a portion of the liquid is then withdrawn from the stone by emptying the tank and maintaining the air pressure, the liquid being forced out into the central bore and withdrawn through the pipe 15. This partly empties the pores in the stone, but leaves their walls covered with the solution ; it also improves the distribution of the binder in the stone. The stone is then allowed to drain, and is finally treated in accordance with the nature of the binding medium. For example, the medium may comprise a phenol-formaldehyde resin dissolved in alcohol with a small percentage of plasticizers, in which case the stone is baked to drive off the alcohol and convert the resin to its insoluble form. Other binders which may be used are high melting point waxes, such as carnauba, candellila and montan, or silicate of soda. The impregnation may be confined to the outer parts of the stone by reducing the time of treatment and then ejecting part of the medium by forcing air into the bore of the stone. The direction in which the medium is introduced may also be reversed.
