Title: Improved process for the production of combustible gas
IPC: C10B57/18
Filed: 1930-02-19
Abstract: 353,034. Combustible gas mixtures. BECKER, A. C., 63, Edisonstrasse, Ober. schoneweide, and BERTELSMANN, W., 18, Bondickstrasse, Waidmannslust, both in Berlin. Feb. 19, 1930, No. 5547. Addition to 335,228, [Class 55 (ii), Gas manufacture &c.]. [Class 55 (ii).] The process of obtaining carbon monoxide-free gas from coal gas according to the parent Specification is modified by mixing the gas with the necessary proportions of combustible and non- combustible gases before the carbon monoxide is removed so that on its removal the final gas has the same heating value specific gravity and speed of ignition as the original gas. Water gas, " double gas" produced from mineral or brown coal, low temperature distillation gases or oil gas may be employed. Part of the monoxide may be removed by liquefaction by copper solutions or by reaction with water vapour and the rest methanated. The reaction with water vapour and the methane catalysis are preferably effected under pressure.

Title: Manufacture of azine-dyestuffs
IPC: C09B17/04
Filed: 1928-02-22
Abstract: 285,840. Soc. Anon. des MatiÞres Colorantes et Produits Chimiques de St. Denis. Lantz, R., and Wahl, A. Feb. 22, 1927, [Convention date]. Azine dyes.-Oxazine dyestuffs are converted into mesoarylazine dyestuffs by treatment with arylamines. Intensive conditions are required in those cases where the arylamine residue first replaces a nuclear hydrogen para to an azine nitrogen. According to one example, 8-phenyl- # :a : #<1> : alpha<1>-dinaphthoxazime is treated with aniline to give the corresponding meso-phenyldinaphthazine, and in a second example, the corresponding unsymmetrical oxazime is similarly treated. The phenyl dinaphthoxazimes may be replaced by other aryldinaphthoxazimes, e.g. the naphthyldinaphthoxazime described in example 8 of French Specification 630,707. Aniline may also be replaced by p- or o-toluidine, anisidine or p-phenylenediamine. The meso-phenyl-8-phenylimino-a : # : a<1> : #<1>-dinaphthazine produced in the first example may be sulphonated. In further examples, 6-phenyl-3-phenylaminophenonaphthoxazime and 8-phenyl-5-phenylaminodinaphthoxazime are similarly treated with aniline in order to yield the corresponding azines. Specification 206,488 is referred to.

Title: Deflection yoke and apparatus for its fabrication
IPC: H01F41/06
Filed: 1970-02-06
Abstract: 1292207 Making electromagnetic coils; coiling helices; electromagnetic forming RCA CORPORATION 6 Feb 1970 [12 Feb 1969] 5760/70 Headings B3A B3E and B3Q [Also in Division H1] In a method of making a wire wound electromagnetic coil, a side portion of the wound coil is electromagnetically rammed towards a bounding surface of a cavity containing the side portion by passing a current pulse through the coil while the side portion is subjected to a transverse magnetic field directed across the cavity transversely of the side portion and of the ramming direction. An electromagnetic beam deflection yoke for use with a colour television tube, for example, is wound on an arbor comprising male and female members 21, 22 supported respectively by mounting plates 23, 24. The plate 24 is mounted on a spindle 25 which passes through a hole 27 in a block 28 in the female member, the spindle being rotated to impart rotation to the members 21, 22 in the direction of the arrows. To wind a coil, one end of the wire is attached to a starting terminal 42 and the members rotated. Side deflecting rods 39, 41 and end wire deflecting vanes 49, 51 guide the wire into the winding cavity of the arbor. The rods 39, 41 extend at right angles to the vanes 49, 51. The female cavity forming member 22 includes a window block 32 on either side of which are recesses 33, 34 for accommodating the side conductors of the coil. The male cavity forming member 21 includes body sections 44, 45 which have configurations conforming to those of the neck and flared bulb sections of the cathode-ray tube with which the coil is to be used. The sections 44, 45 are separated by a window aperture 46 which matches the block 32. When winding is complete, the other end of the wire is attached to a terminal 43. The block 28 and the sections 44, 45 are of permanent magnet material or of a magnetically permeable material, e.g. cold rolled steel. The block 32, spindle 25 and plates 23, 24 are preferably of non-magnetically permeable material, e.g. brass or aluminium. When the coil has been wound, with the mated male and female members 21a, 22a, placed between magnets 55, 56, which may be permanent magnets or the poles of an electromagnet, a current is pulsed through the coil via the terminals 42, 43. Since the coil is in a magnetic field having flux lines 57, 58, the current flowing through side conductors of the coil, shown diagrammatically at 59-59a, 61-61a, causes the conductors to move in the direction of arrows 62-65 thereby providing an even compaction of the turns. Further the conductors immediately adjacent the coil window may be made to lie along lines which are concave to the window and along longer than geodesic lines, Figs. 6-8 (not shown). The wire of the coil may be coated with thermoplastic insulation so that the coatings bonde together due to the heat generated by the electrical pulse.

Abstract: 1278924 Coated sheet material IMPERIAL CHEMICAL INDUSTRIES Ltd 19 April 1971 [6 Feb 1970] 5794/70 Heading B2E [Also in Division G2] A method of producing a photographic film base comprises casting a flat polymeric film, molecularly orienting the cast film by stretching in at least one direction and coating the film with a subbing composition comprising a mixture of a polymeric component and a water permeable component. The polymeric film may be made of polyethylene terephthalate or polycarbonate. The film may first be stretched in one direction and subsequently in the other, or simultaneously in both directions. The polymeric component may be a copolymer of conjugated diolefines with one or more vinyl comonomers. The conjugated diolefine may be butadiene or isoprene and the comonomer may be acrylonitrile, styrene, methyl methacrylate, methacrylic acid or itaconic acid. Terpolymers in which one of the vinyl comonomers is an unsaturated carboxlyic acid, such as itaconic acid, are particularly useful and a preferred copolymer is of butadiene, styrene or itaconic acid. Numerous other suitable polymers are listed. The water-permeable component may be gelatin. Additatives which have a swelling or solvent action on the surface of the film may be included, such as chloro-substituted aliphatic acids, phenols and aromatic alcohols. A photo-sensitive layer may be applied directly on to the subbing layer or a conventional gelatin subbing composition may be applied first.

Abstract: 121,062. Claes, J. April 8, 1918. Mixing liquids in definite proportions. - Relates to apparatus for mixing and feeding or circulating lubricants or other liquids and for maintaining the ingredients of the mixture in predetermined proportions. Oil from one or more casks 1, Fig. 1, and water from a small tank 2 are drawn through a pump 3 and passed into one or more conduits 4 arranged beneath the machines in which the lubricant is to be used The mixture passes into a tank 5 containing water, the supply of which is regulated by a float valve 6, and the lubricant is pumped from the mixing-tank 5 to a distributing - tank 8, from which overhead pipes 9 lead to the machines. Some of the liquid from the tank 8 passes into an hydrometer consisting of a pipe 10, Fig. 2, containing a glass tube or float 15 charged with mercury. The liquid enters at a small inlet 11 at the lower end of the tube 10 and escapes by a larger outlet near the upper end, whence it passes by a pipe 14 to the tank 5. When the density of the mixture is reduced, the float 15 sinks and, by means of a lever 17, raises a fork 19 out of two mercury cups 20, thereby breaking an electric circuit 29 containing the starting and stopping mechanism of the pump 3. If the predetermined proportion of water is exceeded, the float 15 rises, owing to the increased density of the mixture, and the pump 3 is re-started. To prevent any variation of pressure of the lubricant from affecting the float 15, the liquid passes through a pressure-regulator 21, Fig. 5, before entering the tube 10. A gallery 22 round the upper end of the receptacle 21 is divided into concentric compartments 24, 25, 27, and the liquid passes down the central tube 23 into the receptacle 21 and overflows into the compartments 24, 25, 27 in turn. The smallest compartment 25 communicates by a pipe 26 with the inlet 11 of the tube 10, and the outermost compartment 27 communicates by a pipe 28 with the tank 5. When the main pumps are stopped, the hydrometer at once sinks and lifts the fork 19 out of the cups 20.

Microinstructions in a digital computer are determined by a ferrite core matrix controlled by a counter circuit. A 16 x 16 matrix is shown, the columns of which are enabled by a ring counter 1-8 and gates 9-16 and a control flip-flop 21 and gates 34, 35, the state of flip-flop 21 supplying a voltage - E to either the odd- or even-numbered columns, e.g. the even numbers, and the state of the ring counter enabling one of the gates to earth one pair of columns, e.g. gate 12 and columns 46, 47, thus allowing a half current to flow in line 46. A set of four flip-flops 17, 18, 19, 20 and twelve gates 22-33 serve to enable one of the rows. Thus when one of the rows is enabled an input on line 38 of the ring counter causes each alternate column to be enabled and the appropriate ferrite core to be reversed. Amplifiers 57 connected to appropriate cores supply the control pulses to the appropriate parts of the machine so as to carry into effect the required instructions. A set of amplifiers form a word the " 1 "s in which are produced by passing all the amplifier input leads through a particular core. The amplifiers may also be connected to the flipflops 17-20 to change the microinstruction.

Abstract: 793,394. Pneumatic tyres. UNITED STATES RUBBER CO. Feb. 29, 1956 [May 16, 1955], No. 6285/56. Class 144 (2). In a pneumatic tyre having a white or other decoratively coloured sidewall portion 17 adjacent the tyre bead 21, the portion 17 is protected against scuffing, on curbing, by a shoulder S formed by the abrupt termination of a radially outer portion 25 of the sidewall which is profiled to provide a concave part 12, buttressing a relatively thin shoulder tread rib 11, merging gradually through an inflection zone 13 into a convex part 14 projecting axially outwardly of the portion 17. As shown, the tyro tread comprises circumferential ribs of increasing width axially inwardly from the shoulder ribs 11, which latter are supported by the part 12 of the sidewall having a concave curvature of radius A. The inflection zone 13 is located about mid-way between the tread rib 11 and the mid-plane C of the tyre section, the subsequent convex part 14 having a radius B. The convexity 14 provides a thickness E of sidewall rubber protectively projecting outwardly of the white or other sidewall portion 17, and the edge 15 thereof, forming the shoulder S, defines one boundary of the maximum tyre width W. The sidewall portion 25 may be black or of any other desired colour, with the opposite sidewall 14a devoid of the white or other portion 17. The Specification describes the preferred relation between the radii A and B, the thickness E, and the radial extent F of the white sidewall portion 17 from the wheel rim edge, to the width D of the tyre at the radially outer edge of the sidewall portion 17. Specification 763,816 is referred to.
