Title: Improvements in or relating to cathode-ray tubes for indicating tuning
IPC: H01J31/14
Filed: 1953-03-17
Abstract: 747,492. Cathode-ray tubes. PHILIPS ELECTRICAL INDUSTRIES, Ltd. March 17, 1953 [March 20, 1952], No. 7338/53. Class 39 (1). In a cathode ray tuning indicator the surface of the funnel-shaped luminescent screen 3, Fig. 5, is symmetrical with respect to not more than two axial planes and the steepness of axial sections of the surface varies progres. sively with the angle between the plane of the section and a datum plane, the arrangement being such that wher the two deflecting rods 4 are at cathode potential equipotential lines of elliptical form are produced. The screen is a funnel with a circular smaller end and an elliptical or circular larger end. If the larger end is elliptical the major axis of the ellipse cuts the deflection rods 4; if it is circular the sides of the funnel are straight in the plane cutting the rods 4 and convex in a perpendicular plane, Fig. 6 (not shown), or concave and straight in the respective planes, Fig. 7 (not shown), the transition between the straight and curved portions being a smooth one. The cathode hood which screens light from the cathode is formed with a dome 6 and a cylindrical part 5 having two diametrically opposite recesses 8 near the deflection rods; the recesses assist in making the equipotential lines more nearly elliptical. The structure is supported by stay wires 7. The effect of the elliptical equipotential lines is to increase the shadow angle when the two deflecting rods are at approximately cathode potential, Fig. 3 (not shown); if they are at screen potential the equipotential lines are no longer elliptical, Fig. 4 (not shown). An amplifying system may be housed in the same envelope.

Patent GB-492655-A (GB)
Title: Improvements in and relating to the production of protein filaments
IPC: D01F4/00
Filed: 1937-03-18
Abstract: A solution of zein, which may contain plasticizers, is extruded through a filament-forming orifice into a coagulating medium, during which operation the zein is in contact with a reactive aldehyde, and the filament thus formed is heated to evaporate the solvent and promote reaction between the aldehyde and the zein. The solution may be extruded into air or into water or other liquid coagulating medium.  The reactive aldehyde, e.g. formaldehyde may be present in the solution of the zein, or may be added to the coagulating medium. After withdrawal from the coagulating medium, the filament is subjected to an air current heated to a temperature not above 100 DEG C., and is then skeined and baked at 60-90 DEG  C. for 8 to 10 hours. Specification 492,645, [Group V], is referred to.

Abstract: 1,005,070. Semi-conductor devices. STANDARD TELEPHONES & CABLES Ltd. Feb. 22, 1963 [March 1, 1962], No. 8001/62. Heading H1K. In making a semi-conductor device, in particular a tunnel diode, a mono-crystalline body consisting of a first zone of intrinsic semiconductor material and a second zone of one conductivity type is first formed. The region including part of the boundary between the first and second zones is then doped to form a third zone of conductivity type opposite to that of the second zone with a junction between the second and third zones, and the body is finally etched to reduce the area of this junction to the required size. In one example a slice of germanium 3, Fig. 2, degeneratively doped with gallium to provide p + conductivity type, has a layer 2 of intrinsic germanium formed on it epitaxially. A pellet 4, of an alloy of antimony and arsenic, is then alloyed into the wafer to form an + conductivity type zone 5 at the boundary region between the zones 2, 3. An ohmic contact 7 is then alloyed to the opposite side of the wafer and zones 3 and 5 are finally etched electrolytically, or chemically, using suitable masking, to reduce the area of the junction 6 as required, as shown in Fig. 3.

Abstract: Polysters or polysteramides with terminal hydroxyl, carboxyl and/or amine groups and preferably of molecular weight 500-5,000 have their reaction rates with polyisocyanates reduced by treating them prior to such reaction with an inorganic adsorbent.  The polyester being treated may be in molten or solution form and treatment may be effected (a) by stirring the polyester with the adsorbent and then filtering (b) by passing the polyester through a fixed bed of the adsorbent; or (c) by a continuous method using a fluidized bed technique.  Specified adsorbents are silica gel, silicic acid, activated alumina, activated charcoal or carbon, activated bleaching earths, dixie clay, bentonite, fuller's earth, finelydivided slate, talc or feldspar, a mixture of clay and diatomaceous earth, magnesium oxide and calcium carbonate.  The polyesters are those prepared by reacting a polycarboxylic acid (preferably a dicarboxylic acid) with a polyhydroxy compound (preferably a glycol or a mixture thereof with a minor amount of a polyhydric alcohol).  The polyesteramides are those prepared by reacting a glycol, an aliphatic dicarboxylic acid and an amino-alcohol or a diamine.  Many polyester and polyesteramideforming reactants are specified.  Examples describe treating of polyethylene adipate with an adsorbent and afterwards reacting it with p-phenylene diisocyanate.

Title: Improvements in and relating to the production of antibiotic substances
Filed: 1947-03-27
Abstract: Streptomycin sulphate of increased purity is prepared from streptomycin hydrochloride by bringing the impure streptomycin hydrochloride and the sulphate of an organic base, such as pyridine, triethylamine, aniline or dimethylaniline, into common solution in water, a lower aliphatic alcohol, or a mixture of water and a lower aliphatic alcohol and, where water or a liquid consisting mainly of water is used, adding a water-miscible solvent to precipitate streptomycin sulphate.  The solutions of the impure streptomycin hydrochloride and the sulphate of the organic base may be made separately and mixed together, or the streptomycin hydrochloride or a solution thereof may be added to a suspension of the sulphate of the organic base in water.  With solutions of streptomycin hydrochloride containing less than 100 units per mg. it is advantageous to add the water-miscible organic solvent in portions and to retain those portions of precipitate showing enhanced antibiotic activity.  In examples, streptomycin sulphate is prepared from the hydrochloride by treatment with (1) pyridine sulphate in methyl alcohol; (2) pyridine sulphate in aqueous methylated spirit; (3) pyridine sulphate in water; (4) triethylamine sulphate in water; (5) aniline sulphate in water; (6) dimethylaniline sulphate in water and (7) and (8) pyridine sulphate in aqueous ethyl alcohol.

[Also in Divisions G4-G6] In a gas cooled nuclear reactor the fuel charge tube, 1, is provided with a port, 8, the dimensions of which change in correspondence with gas temperature. The temperature of the sleeve, 2, is at the temperature of the gas in the plenum, 9, while the temperature of 1 varies with the temperature of the gas in 1, heated by the fuel element. Thus, tube 1 changes length as the gas temperature increases and causes 8 to increase in size.
