Title: Rubber hydrohalides
IPC: C08C19/16
Filed: 1937-10-14
Abstract: 509,490. Hydrohalogenated rubber. WINGFOOT CORPORATION. Oct. 14, 1937, No. 27947. Void. Convention date, Jan. 28. [Class 70] Rubber hydrochloride and rubber hydrobromide are obtained by passing gaseous hydrogen chloride or hydrogen bromide into a solution of rubber in diethyl ether ; the solution is preferably maintained at about room temperature during the treatment and is then allowed to stand until the rubber hydrohalide has precipitated. The properties of the product may be varied by varying the amount of milling of the rubber prior to solution, by varying the amount of hydrohalide passed into the solution and thus the halogen content of the product and by varying the temperature of reaction.

Title: Improvements in circuits for generating, amplifying or modulating millimetre waves
IPC: H01J25/00
Filed: 1952-11-06
Abstract: 719,435. Travelling-wave tubes. PHILIPS ELECTRICAL INDUSTRIES. Ltd. Nov. 6, 1952 [Nov. 9, 1951], No. 27982/52. Addition to 704,378. Class 39(1). In a discharge tube for generating, amplifying or modulating millimetre waves and having a resonant circuit comprising a plurality of generally parallel coplanar wires stretched on a conductive frame, their spacing being small compared with their length, which is about #/2, and the voltages on adjacent wires being in phase opposition, and in which the electron beam passes normally to the axes of the wires but parallel to the plane in which they lie, as described for example in the parent Specification, adjacent wires 3, 4, Fig. 2 are slightly inclined in opposite directions to the mean direction of their axes so that the distances between adjacent ends of the wires are alternately smaller and greater than the mean distance the ratio between the smaller and greater distance lying in the range 0.7 to 0.9. This ensures that adjacent wires will oscillate in phase opposition with voltage nodes at their ends. The resonant circuit is constructed by winding wire on a frame in a left handed winding operation followed by a right handed winding operation, and removing the wires on one side of the frame after the remainder have been fixed to the frame by soldering. The frame is of molybdenum sheet. Dimensions of an example are given.

The relative speeds of the rolls 6, 6a and a haul-off mechanism (not shown) are adjusted to give uniform feed, and the braiding is allowed to ruck up prior to its entry into the head 8 so that it is not under any tension other than that required to pull it thereinto. The ring 5 has a tapered bore for passage of the braiding, the diameter being smaller where the braiding enters than where it exists, while the mandrel 10 is of less diameter than the braiding and its ends are machined to have a smooth finish, and are preferably of a hemispherical shape, though they may be frusto-conical. A tunnel heater (not shown) may be positioned adjacent the orifice 11 to heat the sheathed braiding. The rims of rolls 6, 6a may be coated with pliable plastics sheaths 7, 7a.

Title: Improvements in the production of free-flowing anhydrous sodium sulphate
Inventor: SPORMANN WALTER
IPC: C01D5/02
Filed: 1960-08-16
Abstract: Free-flowing anhydrous sodium sulphate is produced from solutions containing sodium hydrogen sulphate, which have been obtained in the production of hydroxylamine, by neutralizing with sodium hydroxide, separating sodium sulphate decahydrate from the solution, melting the decahydrate in the presence of SO2 and/or a compound which forms SO2 on heating to at least the fusion temperature of the decahydrate, separating the deposited anhydrous (free from water of crystallization) sodium sulphate, and drying.  A sulphur-dioxide-forming compound may be added to the decahydrate before, during, or after melting.  In an example, sodium hydrogen sulphite solution obtained by dissolving sodium pyrosulphite in water is added with the sodium sulphate decahydrate to a vessel heated to about 90 DEG C. to effect melting. Alternatively, solid sodium pyrosulphite may be employed.

Abstract: 688,112. Magnetron oscillators. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 29, 1947 [Oct. 31, 1946], No. 28893/47. Class 39(i) [Also in Group XL(c)] A magnetron oscillator comprises a plurality of anodes arranged around a central cathode, and separate tank and load circuits connected to opposite anodes 18, 19 as in Fig. 2, or to opposite pairs of anodes 1, 2 and 4, 5 as in Fig. 1, or 45, 46 and 47, 48 as in Fig. 4. Intermediate anodes 20, 21 in Fig. 2, 3, 6 in Fig. 1, and 49, 50 in Fig. 4, differing in high frequency from the adjacent anodes, serve as shields between the tank and load circuits. The tank circuit, is short-circuited and serves solely to determine the frequency of the system, and the load circuit serves solely for deriving the output energy. In Fig. 2 these circuits are coaxial lines, in Figs. 1 and 4 Lecher lines. The tank circuit is tunable by adjusting a slidable short-circuiting member, 38 in Fig. 2, to vary the frequency. The anodes 18, 19 of Fig. 2 are supported from insulating end closures 30, 31 of the metal envelopes 17. Magnetic pole-pieces, permanent or of soft iron, are fixed to the envelope 17 opposite the ends of the cathode 22. Specification 641,489 is referred to.

Abstract: 762,921. Fabrics composed of adhesivelyunited threads. MINNESOTA MINING & MANUFACTURING CO. Oct. 7, 1954 [Oct. 7, 1953], No. 28975/54. Class 140. A non-woven decorative picot ribbon comprises a flat filament layer formed of a large number of continuous lineally aligned viscose rayon filaments to which is bonded a superimposed open mesh layer formed of continuous lineally directed sinuous cellulose acetate monofibres mutually offset and fused together at their crossing-points to form a network with a lineally repetitive pattern with loops extending beyond the sides of the filament layer to provide the ribbon with pearl edges. The lineallyaligned viscose filaments are of hair-like fineness and are much finer than the mono-fibres of the open-mesh layer. They may extend uniformly across the width of the filament layer or constitute two or more separate stripes. They may be present in the form of twisted yarns or in the form of tows that are spread out. They may be coated with a water-resistant organic-polymer binder sizing, such as a vinyl resin, which may be included in a dye bath and the filaments simultaneously dyed and coated. The superimposed open-mesh layer is preferably contageously bonded to the flat filament layer. A large number of viscose-rayon continuous filaments forming a tow 1, are drawn over and under a series of smoothing bars 2, then pass between two teeth of the positioning rake 3 and then over the coating roll 4 which clips into the bath 5 which contains dye and sizing resin dissolved in a volatile solvent. The filament strip is then drawn under positioning bar 8 where it meets the upper surface of the endless carrier belt 9 as it passes over supporting roll 10. A vertical spinneret head 14 is mounted above the carrier belt and is fed with a viscous cellulose acetate solution through a tube 15. The spinneret extruder, which has five holes uniformly spaced in a straight line parallel to the direction of motion of the carrier belt, is reciprocated transversely of the belt. The freshly formed ribbon 16 passes on the carrier belt through drying oven 11 and at 17 it is drawn towards a wind-up roll (not shown). Different structural designs can be achieved by varying the relative speeds of the spinneret and the carrier belt, the mode of reciprocation of the spinneret, the number and arrangement of the extrusion holes, the distance of the spinneret above the belt and the viscosity of the extrude solution.
