Title: Method of producing iron powder
IPC: B22F9/22
Filed: 1946-03-21
Abstract: Iron powder is produced by reducing iron ore at a temperature below its softening point by rendering the iron powder rustless and separating the non-metallic particles from the rustless iron in an aqueous liquid.  The iron particles are rendered rustless during or after reduction by treatment with nitrogen or a substance containing nitrogen, e.g. ammonium or cyanide compounds or silicon or silicon containing compounds, e.g. silica or silicon hydrogen compounds or by means of a passivating liquid, e.g. sodium or calcium hydroxide, potassium bichromate, or potassium ferrocyanide.  The reduction may be made in a hydrogen atmosphere or in a treated natural gas and the ore may be mixed with 10 per cent of lime.  The gangue may be separated by froth flotation, settling, tabling or wet magnetic separation in a passivating solution having a pH value over 7.  It is stated that the iron particles become coated with a nitride or a silicon compound.

Title: Improvements relating to the control of electric traction motors
Inventor: RAMSDEN HERBERT KAYE
IPC: H02P1/02
Filed: 1953-03-30
Abstract: 738,328. Control of D.C. motors; controllers. METROPOLITAN - VICKERS ELECTRICAL CO., Ltd. March 22, 1954 [March 30, 1953], No. 8766/53. Class 38 (3). Traction motors have a number of armature resistance units R1-R15 controlled by contactors C1-C15 with operating coils CC1- CC15 regulated by means of a drum MD. A line switch LS has a coil CLS whereby the switch is closed on the first notch of the drum and the resistance contactors are successively energized as the controller is moved to the sixteenth notch. An auxiliary drum AD cooperates with contact fingers AF2, AF3, connected respectively with coils CC14, CC15, the arrangement being such that resistor R14 is short-circuited in the first operative position of the auxiliary drum and resistors R14, R15, are short-circuited in the second operative position thereof, independent of the position of the main drum. Acceleration normally proceeds under the control of the drum MD alone, but, when voltage increments are required, the auxiliary drum is actuated to one of its operative positions, so that, when the motors reach the maximum speed with the auxiliary controller in the second operative position, the latter may be returned to the " off " position and the drum MD advanced to its next notch. The values of the resistors R14, R15 are small in comparison with the earlier resistance sections. 'When the handle MH of the main controller is moved from one notch to another, a latch MT is operated and push rod PR1 rocks a lever L. Thus, if the handle AH of the auxiliary controller is in an operative position, a push rod PR2 releases latch AT and the handle AH is returned by spring BS to the " Off position. No notch corresponding with the " off " position of the handle AH is provided, so that it is not necessary to operate the latch AT when moving the auxiliary controller from the " off " position. The auxiliary drum may be incorporated in the main controller, and a reverser lever, or a member for selecting the various motor combinations in the case of series-parallel equipment, may be employed for the auxiliary handle AH. The contactors for controlling the armature resistors may be of the electromagnetic, electro-pneumatic, or of the cam-operated types.

Title: Improvements in or relating to oxidation agents and processes
Inventor: KATZ MORRIS
IPC: C01B32/50
Filed: 1949-03-31
Abstract: A porous granular oxidation agent, capable of substantially completely oxidizing carbon monoxide at normal temperatures (0 DEG -60 DEG C.) and at humidities of up to 100 per cent, comprises a mixture of silver permanganate and a solid inorganic oxide of a solid element in which the silver permanganate is dispersed in finely-divided form upon and throughout the oxide by being formed in the presence of the oxide by reaction between a soluble silver salt and an alkali metal permanganate, the oxide having no more than a low solubility in water and, in the presence of water, being substantially unreactive with the silver salt employed. Suitable oxides are ZnO, Fe2O3, MoO3, Co2O3, TiO2, chrysotile asbestos, CuO, MnO2, CeO2, Sb2O3, NiO, SnO2, Pb3O4, powdered silica gel, ZrO2, CdO, V2O5, Al2O3, talc, kaolin, and kiesel guhr.  When using kaolin or kieselguhr, a water content of 8-11 per cent in the final product is preferred; with the other oxides the water content should not exceed 2 per cent.  Optimum activity in the oxidation of carbon monoxide is shown by products containing 60-75 mole per cent ZnO, 67-80 mole per cent CuO, 50-70 mole per cent MoO3, 33-50 mole per cent Sb2O3, and 33-50 mole per cent Pb3O4.  Examples describe the preparation of agents by mixing a solution of potassium permanganate with a paste formed from zinc oxide and silver nitrate solution, or by mixing silver nitrate solution with a paste formed from zinc oxide and potassium permanganate solution. The product is cooled to 0-5 DEG C. filtered, pressed at 5-10 tons per square inch cured for 7-28 days, granulated, and dried.  The agents may be used in respirator canisters or as indicator agents in conjunction with a multithermocouple cell and an e.m.f. measuring apparatus for the determination of carbon monoxide in air.  Tests are described showing the effect on the breakdown time of the agents of variations in the curing time and the pressure used in the preparations, and also showing the relation between breakdown time and the initial concentration of carbon monoxide in the gas treated, the rate of flow, temperature and humidity of the gas, the dimensions of the bed of agent, and the granule size. The agents will effect the oxidation of carbon monoxide in atmospheres not containing oxygen.  The Specification refers to the prior use of a composition containing silver permanganate, calcium oxide, and calcium chloride.
