Title: Bonding material
Inventor: PINNINGTON AUSTIN ROBINETTE
IPC: C22B1/243
Filed: 1962-05-03
Abstract: A process for preparing a pellet mix of an iron oxide ore or ore concentrate comprises mixing the ore or ore concentrate in a finely divided form with a natural calcium montmorillonite and an alkali metal salt (which is soluble in water and the anion of which forms a calcium salt having a solubility in water at 0 DEG  C. of less than 0.1 parts by wt. per 100 parts by wt. of water), together with sufficient water to allow binding together of the constituents of the mix.  The calcium montmorillonite may be mixed with the alkali metal salt and water prior to mixing with the ore or ore concentrate.  The amount of alkali metal salt used may be in excess of the cation exchange capacity of the calcium montmorillonite. Specified alkali metal salts are sodium oxalate and sodium carbonate. The mix may be formed into green pellets which may then be fired.

Patent GB-462269-A (GB)
Title: Improvements in or relating to the coating of aluminium and its alloys
IPC: C23C22/83
Filed: 1936-06-19
Abstract: An adherent glazing coating is produced upon aluminium and its alloys, by first giving the metal a film coating of oxide, and then applying a coating of urea formaldehyde resin or thio-urea formaldehyde resin.  The oxide film may be produced by anodic oxidation or by a purely chemical treatment of the metal, and this film or the resin coating may be coloured.  The resin, to which may be added pigments, plasticizers, hardening agents such as ammonium nitrate or chloride, and other synthetic resins, may be applied in solution or in suspension, by brushing, spraying or dipping, and, after drying, the resin coating may be hardened by heating.  Several layers, similar or differing in composition, may be applied, each layer being dried and hardened by heating. According to an example: powdered urea-formaldehyde resin is dissolved in a mixture of water, alcohol, triacetin and monomethylic ether of glycol, titanium white is added, and the whole homogenized.  The mass is sprayed on to the oxidized aluminium, dried, and hardened by heating for 3--5 hours at 120--130 DEG  C.  According to the Specification as open to inspection under Sect. 91, resins formed by the condensation of formaldehyde with any carbamide may be used, but this subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to valve amplifiers
Inventor: WATTON WALTER LESLIE
IPC: H03F1/13
Filed: 1952-07-08
Abstract: 745,429. Frequency selective amplifier circuits. ELECTRIC & MUSICAL INDUSTRIES, Ltd. July 1, 1953 [July 8, 1952], No. 17105/52. Class 40 (6). In an amplifier having two or more stages arranged to operate over a predetermined frequency and wherein the amplifier tends to oscillate at a higher frequency, the coupling impedances are chosen to be different so that while the performance is unaffected, the coupling impedances at the higher frequency are such that the tendency to parasitic oscillation is substantially avoided. In the amplifier employing valve stages 1, 2 and 3, parasitic oscillation tends to occur due to feed-back over the heater-cathode capacitance and the heater leads, the inductors 4, 5 and 6 behaving as chokes and the decoupling capacitors as small inductors at the parasitic frequency. By tapping down the grid connections on inductors 4 and 6 the associated circuits are effectively detuned from that associated with inductor 5. Alternatively, the capacitors 20, 22 may be connected to taps on the inductors 4, 6. In a modification a lengthened lead or loop of wire may be included in series with a coupling capacitor, or the leakage inductance of an intervalve transformer may be employed to effect de-tuning. In a further modification the effective anode or grid to earth capacities may be increased.

Filed: 1938-06-09
Abstract: 508,136. Depositing rubber from latex. INTERNATIONAL LATEX PROCESSES, Ltd. June 9, 1938, No. 17133. Convention date, June 19, 1937. [Class 70] Rubber is deposited from latex on fibres free from coagulant, by adding to the latex a coagulant and stabilizing agent, so that the latex is stable at the temperature of treatment in the absence of fibres, but unstable in the presence of the fibre to be treated, and placing the fibre in contact with a small quantity of such latex. The bringing of the latex into the isoelectric zone as described in Specification 508,137 is disclaimed. The fibres may be introduced into a bath of the latex, and squeezed until they contain 50-200 per cent of their weight of latex. The treatment may be carried out at room or elevated temperature. Numerous examples are given in the Specification of which the following is typical. A latex mix consisting of 100 parts of rubber as 60 per cent latex, 2 parts of potassium hydroxide, 0À4 parts of glue, 1À25 parts of "Aquarex D " (stabilizer), 0À5 mercaptobenzothiazole, 4 parts of casein, 2 parts of zinc oxide, 0À5 parts of " BLE," (antioxidant, condensation product of acetone and diphenylamine), diluted with water to 40 per cent solids content, was made into a treating bath by adding to 10 parts by weight of the solids, 3 parts of " Sulphanol " (R.T.M., a sulphated fatty alcohol stabilizer) 2À7 parts of formic acid, and 84À3 parts of water. Wool flannel immersed for 60 minutes at room temperature increased in weight by 12À2 per cent by deposition of solids from the bath.

Title: Counterflow method of manufacturing methyl methacrylate and acrylate
IPC: C07C69/54
Filed: 1956-06-07
Abstract: Dimethyl ether formed as an undesirable byproduct during the manufacture of methyl acrylate or methacrylate by esterification of the corresponding acid and/or amide with methanol in a strongly acid medium is retained within the reaction system by scrubbing the reaction gases, after condensing the bulk of the ester, with at least one of the reactants to absorb the dimethyl ether which is re-cycled in the absorbed condition.  This inhibits the continued formation of ether and permits a higher esterification temperature.  Apparatus are described for reacting the sulphuric acid mixture resulting from the hydrolysis of acrylonitrile with methanol to give methyl acrylate, and absorbing the dimethyl ether formed in the inflowing methanol or sulphuric acid mixture.
