Title: Improved methods of processing polytetrafluorethylene and products therefrom
Inventor: VINCENT RUSSELL SWALE
IPC: C08L27/18
Filed: 1950-04-20
Abstract: Compositions containing polytetrafluoroethylene in finely divided form are made by mixing coarse grains of polytetrafluorethylene, including scrap polymer in partially sintered form, with a viscous and sticky binder in a mill, and then milling this mass until the particles are reduced in size to the desired extent.  Viscous and sticky binders specified are materials having as principal constituents rubber-like materials, for example natural or synthetic rubber, polyisobutylene, if desired in admixture with toluene, and silicon elastomers, or mixtures thereof with a mineral oil.  Other finely divided materials which may be included in the compositions are metals, carbon black, and pigments such as calcium seleno sulphides, cobalt blue, and chrome green.  The compositions may be used for filling cable joints, for insulation of electrical conductors, and in the production of sheet material and shaped articles. Specification 706,012 is referred to.

Abstract: 1,221,381. Yeast-leavened doughs. FOREMOST-McKESSON Inc. 31 March, 1969 [1 April, 1968], No. 16834/69. Heading A2B. [Also in Division C6] Yeast stable brews capable of being held e.g. for up to 24 hours and subsequently used in the leavening of doughs are prepared by: (1) mixing essential brew ingredients (water, yeast, yeast foods and sugar) with one or more of the following, which act as stabilizing agents, viz. cereal flours, soya flour, dry non-fat milk, whey and calcium carbonate, the mixed brew containing sugar in an amount just sufficient to initiate yeast fermentation reactions to produce gas at a desired uniform and relatively high rate; (2) holding the stabilized brew at a temperature within the range 75-95F. for not more than 45 minutes to achieve the desired gassing rate, the stabilizing agent being effective to control the pH of the brew to within a range of from 4.0 to 4.8 without interfering in the gas producing activity of the yeast in the brew; (3) cooling the brew to a temperature of 60F. or below, as by the addition of ice, to effectively inhibit the gas producing activity of the yeast cells and to temporarily suppress yeast fermentation reactions; and (4) holding the brew at a temperature of 60F. or below. The brew may be mixed with additional ingredients including flour, shortening, sugar, salt and water, to form a leavened dough. Activating agents (cysteine, glutathione and sulphite salts) and maturing agents (potassium bromate, iodate or persulphate, calcium and acetone peroxides, and azodicarbonamde oxidizing compounds) may be included in the dough formulation. Suitable amounts of the stabilizing agents in the yeast brew are: (i) 3-7% cereal flour based on the total cereal flour requirements of the dough, or (ii) 3-10% of the other stabilizing agents mentioned, based on the flour content of the dough (only 2-5% when used in conjunction with cereal flour as a stabilizing agent). Examples 3 and 5 describe the use of the yeast stable brew in a straight dough bakery process and a continuous bread-making process, respectively.

Abstract: 1,221,493. Modifying the dye-affinity of polyamides. NIPPON RAYON K.K. 10 April, 1968 [11 April, 1967; 11 Jan., 1968], No. 17398/68. Heading C3R. [Also in Divisions D1-D2] Polyamides exhibiting enhanced affinity for basic dyestuffs and inhibited affinity for acidic dyestuffs are prepared by heating a mixture of (a) a synthetic linear polyamide having terminal amino groups or (b) the reaction components thereof, and a triazine derivative of the formula in which R<SP>1</SP> is aryl or substituted aryl; R<SP>2</SP> is or where R<SP>4</SP> is a, divalent or trivalent aromatic group or a divalent aliphatic group, R<SP>5</SP> is hydro- .gen or a monovalent aliphatic group, M is the atomic equivalent of alkali metal, alkaline earth metal or manganese, n is one when R<SP>4</SP> is divalent or two when R<SP>4</SP> is trivalent, and R<SP>3</SP> is -OR<SP>1</SP>, -R<SP>2</SP> or -OH. Many triazine derivatives and conventional polyamides including those derived from lactams and amino acids are listed. The triazine derivative reacts with the amino groups via the -OR<SP>1</SP> group(s) which is (are) replaced by the amino group(s). When the triazine derivative is the sole additive it also functions as a viscosity stabilizer. The triazine derivative and a conventional diamine or diamines of the formula may be admixed, and if desired reacted to form a prepolymer, and added to the polyamidecomponent mixture, the whole being copolymerized. Conventional additives such as delustrants (e.g. TiO 2 ), pigments and antioxidants may be added The above polyamides may be used to produce yarns, fabrics, bristles, films and mouldings. The yarns may be subsequently dyed or formed into tricot fabrics using also conventional polyamides prior to crossdyeing.

Title: Process for the manufacture of a polishing agent comprising zirconium oxide
IPC: C09K3/14
Filed: 1963-05-03
Abstract: Zirconia is produced by the reduction of zirconium ores containing silica with carbon, preferably in an electric arc furnace, wherein 60 to 75% of the amount of carbon required by the equation: ZrO2SiO2 + C = ZrO2 + SiO + CO is mixed with the ore and the reaction product is comminuted and dressed in the usual manner. After removal from the furnace, the product is crushed, ground and then treated with a dilute mineral acid to remove any iron, to obtain a grain of specified size, preferably 3 to 5 m , which is isolated by sedimentation.  Washing out is usually effected by decanting or centrifuging but, when decanting the supernatant liquor, traces (i.e. 0.01% to 0.001% calculated on the zirconia content) of non-ionic aliphatic amides of high molecular weight, i.e. 1 x 106 to 3 x 106, may be added.  These amides may be the saponification products of polyacrylic compounds, e.g. polyacrylamide, and give an easily filterable slurry, which may be dried and broken up into particles of the former grain size.

Title: Improvements in or relating to television apparatus incorporating pick-up tubes
Inventor: THEILE RICHARD
IPC: H04N3/34
Filed: 1952-07-16
Abstract: 735,523. Television pick-up tubes. PYE, Ltd. July 15, 1953 [July 16, 1952], No. 17991/52. Class 39 (1). [Also in Group XL (b)] In a pick-up tube of the high velocity scanning type, such as an iconoscope or image iconoscope, variation in width of the scanning lines due to the beam cross-section being larger towards the edges of the screen, where it impinges at a more oblique angle, is reduced or avoided by oscillating the beam transversely to the lines at a frequency high compared to the line frequency, the amplitude of oscillation being varied over the length of each line from a maximum at the centre to a minimum at the edges. In addition the amplitude of oscillation may be varied in successive lines of each frame to compensate for the changing angle of incidence of the beam for the successive lines. The required high frequency oscillation may be obtained by amplitude modulating a constant amplitude oscillation with waveforms derived from the line and frame scanning generators. For accurate compensation which requires a complex modulation waveform, a copy of the scanning pattern is produced on a opaque member by drawing or photography. The opaque member is then incorporated in a monoscope tube and is scanned to produce a signal which is used to amplitude modulate the highfrequency oscillations. Alternatively the copy of the scanning pattern is formed on a slide 1 positioned in front of a flying spot scanner 2, the light passing through the slide falling on photo-cell 3 which may incorporate an electron multiplier. The output from the photo-cell 3 is amplified at 6 and amplitude modulates the high-frequency oscillations at 7, the resulting amplitude modulated waveform being fed to deflecting coil 9 separate from scanning coils 10. The high-frequency oscillations are preferably of a frequency at least twice the highest modulation frequency component of the video signal, e.g. 20 megacycles-per second.
