Title: Method for producing fiber texture and cube-texture sheets of iron-base alloys
IPC: C21D8/12
Filed: 1960-10-13
Abstract: A process of producing a thin magnetic sheet having a large proportion of cube-on-face oriented grains from a thicker sheet with [001] fibre texture comprising not more than 6% by weight silicon, and/or not more than 8% by weight aluminium, and/or not more than 5% by weight molybdenum with the balance being iron except for small amounts of impurities, said process comprises the steps of (1) cold rolling the fibre texture sheet to effect a reduction in thickness of from 40% to 80%, (2) annealing the resulting thinner sheet at a temperature between 400 DEG C. to 600 DEG C. for 4 to 48 hours to obtain partial primary crystallization, (3) completing the anneal at a temperature between 700 DEG C. to 1000 DEG C. for a period between 1/2 hour to 12 hours to obtain substantially complete primary recrystallization and (4) repeating the steps (1), (2) and (3) at least once in the order set forth whereby a thin magnetic sheet is produced which has at least 40% of the grains with (100) [001] orientation with the crystallographic direction [001] being in the direction of rolling.  The thicker sheet with [001] fibre texture is produced from a hot rolled plate by cold rolling the plate to effect a 40% to 80% reduction in thickness, annealing the reduced plate at a temperature of from 700 DEG C. to 1000 DEG C. for from 1 to 5 hours in wet hydrogen to provide recrystallization and decarbonization and annealing the recrystallized plate at a temperature of from 1100 DEG C. to 1300 DEG C. for from 6 to 48 hours in dry hydrogen whereby the [001] fibre texture sheet is obtained.  A thin magnetic sheet produced by the above process is subjected to a final anneal at a temperature from 1100 DEG C. to 1300 DEG C.  Several examples of the process are given in the Specification.  Specification 882,810 is referred to.

Title: Alkoxy-terminated siloxane polymers
IPC: C08G77/00
Filed: 1954-12-09
Abstract: Alkoxy-terminated polysiloxanes are made by reacting, under anhydrous conditions and in the presence of an alkaline catalyst, a siloxane containing an average of from 1 to 2 hydrocarbon radicals per Si atom and free from Si-bonded alkoxy radicals, preferably a dialkyl or diaryl cyclic trimer or tetramer, with a silicon compound having at least one hydrocarbon radical and at least one alkoxy group attached to the same silicon atom.  The reaction may be effected at room temperature but is preferably conducted at 50 DEG  to 200 DEG  C. Catalysts specified are potassium silanolate, potassium and sodium hydroxides, potassium methoxide and butoxide, tertiary amines and tetramethyl ammonium hydroxide. The molar ratio of the alkoxy compound to the siloxane may be e.g. from 1:1 to 1:100.  The silicon bonded hydrocarbon radicals of the reactants may be alkyl, vinyl, aryl or aralkyl radicals, and the alkoxy silicon compounds may be alkoxy silanes, alkoxy polysiloxanes or alkoxy silcarbones in which the R1 of the OR1 groups may be the same as the Si-bonded R radicals, and may also contain nitrogen, e.g. bis(2-aminoethoxy) dimethylsilane.  The molecular weight of the final polymer may be greater or less than that of the initial polymer.  If desired, light fractions may be stripped from the reaction products.  The products may be used as oils, dielectric agents or intermediates or be reacted with alkyd resins.  In examples: (I) to (II) dialkoxy silanes are reacted with cyclic diorganopolysiloxanes, the catalyst concentration or time of reaction being varied; (12), (13) trialkoxy silanes are reacted with cyclic diorganosiloxanes; (14) trialkoxysilanes are reacted with mono-organosiloxanes; (15) to (20) specific alkoxy organosilicon polymers are prepared, the polymer of Example (16), having the general formula (O3SiRSiO) (R12SiO)n(R11)6, being made by reacting the hydrolysate of dimethyldichlorosilane with hexaethoxydisilylethane.

Abstract: 806,683. Coaxial line terminations. ELLIOTT BROS. (LONDON) Ltd. Dec. 12, 1956 [Dec. 12, 1955], No. 35668/55. Class 40 (8). [Also in Group XL (a)] A discharge tube adapted to be inserted into a waveguide to extract energy therefrom comprises a cathode arranged axially of a cylindrical anode to provide a coaxial transmission line, the cathode extending beyond at least one end of the anode, a transformer associated with said cathode extension adapted to transform the mode of the energy propagated through the waveguide to a mode for propagation along the anode-cathode line, and a body of lossy dielectric material surrounding the cathode at a location spaced from the transformer in the direction of energy propagation. In Fig. 1, the discharge tube is an elongated tubular glass envelope 3a, 3b which may contain gas at low pressure. The anode 2 is supported by a sleeve 4 having an annular flange 5 extending through the envelope to form an external connection. The flange 5 is flexible so as to accommodate axial expansion. The cathode 1 is a hollow tube extending beyond the anode at both ends. At one end it is connected to a transformer 6. At the other end it is supported by a spider 7, and connected via a spring 11 to a contact-pin 13 extending through the end of the envelope, the pin being soldered to a disc 17. A hollow metal sleeve 15 of frusto-conical form is slipped over this end of the tube, its narrower end being coplanar with the end of the anode 2. Cooling fins 18 may be attached to the sleeve. The space between sleeve and tube is filled with a lossy material 16 such as a suspension of ferromagnetic (e.g. carbonyl-iron) dust in a resinous binding medium. The energy propagated along the anode-cathode line is gradually absorbed by the lossy material, with minimal reflection. The dimensions are such that when the tube is inserted into the rectangular waveguide 29, one end of the anode sleeve is level with one wall of the waveguide while the transformer 6 extends through the other wall. A choke block 28 surrounds the junction of the tube with the waveguide. The tube is secured to the choke block by means of a threaded nut 25 which engages with a threaded member 27 forming part of the block. The disc 5 and a contacting metal ring 41 are clamped between insulating washers 24, 40. The ring 41 is connected via a lead 42 and pin 43 to a plug 31 for connection to a coaxial cable, which thus takes the anode potential to a suitable indicating device. The lossy material may be within the envelope instead of outside it, and Figs. 3-8 (not shown), illustrate different forms of distribution and arrangement.

Title: Improvements in compositions of matter and methods of their preparation
IPC: C08C4/00
Filed: 1929-11-21
Abstract: The process of the parent Specification-the treatment of rubber with water at temperatures above 100 DEG  C.-is modified by the addition of sodium chloride, for example, about 1 per cent to the treating water.  This promotes the decomposition of some of the contained proteids into soluble cleavage products, and renders others insoluble in water.  To ensure that all the chloride is removed, it is preferable to add a softener such as petrolatum, pine tar or palm oil before the subsequent washing.  The rubber thus obtained may be mixed with hard waxes, balata, &c. for cable insulation and like purposes.
