Patent GB-1176756-A (GB)
Title: A Process for Repressing the Formation of SO3 in Gases Ensuing from the Roasting of Iron Pyrites.
Inventor: WIKLUND JOHAN ELOF
IPC: C01B17/52
Filed: 1968-05-22
Abstract: 1,176,756. Sulphur dioxide. BOLIDEN A.B. 22 May, 1968, No. 24410/68. Addition to 917,480. Heading C1A. Roaster gases containing S vapour and SO2 are separated from the magnetite cinder produced by roasting iron pyrates in a fluidized bed with a gas containing oxygen as described in Specification 917,480 and said roaster gases are cooled to below 420‹ C., but not below the temperature at which the sulphur content of the gas begins to condense, before the introduction of the oxygen containing gas necessary for the complete combustion of S. This improvement in the aforementioned process represses the formation of SO3. Preferably, the gas is cooled in a waste heat boiler. The oxygen containing gas may be introduced before or after the roaster gas has passed through an electrofilter.

Abstract: 1,274,913. Gaseous purification of steel. NIPPON KOKAN K. K. May 13, 1969 [May 13, 1968], No.24426/69. Heading C7D. Steel is treated with a non-harmful gas which is blown in through one or more permeable refractory plugs arranged on the ladle bottom at least 30 degrees away from the line joining the centre and the nozzle of the ladle, at such a pressure and volume that non-metallic inclusions in the melt are made to adhere to a viscous slag layer formed on the internal walls of the ladle by the slow circulation of the bath. The gas may be Ar, Nz, Cl 2 , CCl 4  or CF 4 , any oxidizing slag is preferably removed from the steel before it is put in the ladle and it is recommended that a non- oxidizing powder refractory or chaff is added to the steel in the ladle.

Title: Safety device for cutting and pressing machines
IPC: F16P3/16
Filed: 1963-06-19
Abstract: 1,098,071. Machinery guards; controlling Clutches. TRICO-FOLBERTH Ltd., and G. E. VICKERSON. Sept. 21, 1964 [June 19, 1963]. No. 24483/63. Headings F2J and F2L. In a machine comprising an operating tool, an anvil, and a guard movable to a safety position at which it prevents access to the working area of the operating tool upon the anvil, actuation of a primary starting control causes the guard to move towards the safety position with a force insufficient to cause injury, and when the guard reaches the safety position, a secondary starting device for a power stroke of the operating tool towards the anvil is actuated, the guard being locked in its safety position during the power stroke of the operating tool. If any obstruction prevents the guard reaching the safety position, no power is supplied to the operating tool, although the actuating movement of the primary starting control member is still completed. As shown, depression of a primary starting control link 14 causes downward movement of a claw link 16 and pivotal movement of a bellcrank lever 20, which pushes the end of a drag link 26 against the action of a spring to free a shoulder 28 from engagement with a side 9 of a pivotally mounted guard 10, so that, if no obstruction is met, the guard 10 falls freely under gravity to its guarding position. A link 30 forms a lost-motion connection between a side 11 of the guard 10 and a starting mechanism 32 so that when the guard reaches its guarding position, a clutch is actuated and the power stroke of the press commences. A spring-loaded latch 38 locks the side 9 of the guard 10 in its lower position during the downward stroke of the ram press. The drag link 26 is oscillated down and up during the press cycle and raises the guard 10 during its upward movement. A cam surface 52 on the link 26 actuates an air valve 50 controlling a unit 48 fitted to the brake of the press so that when the guard 10 is in its raised position, the press crank-shaft is locked. In a modification, a guard 60, Fig. 6, is carried by a bracket 62 pivotally mounted at 64 on the machine frame. A lever 66 is also pivotally mounted at 64 and is connected at one end to a primary starting control rod 68, engages a pin 92 of a lost-motion connecting lever 85 attached to a clutchengaging lever 100, and is engaged by a disc 78 mounted on bracket 62 to support the guard 60. A sliding block 70 carries a pin 72 which is disposed between discs 74, 76 mounted on the bracket 62. When the control rod 68 is depressed, the guard 60 moves to its guarding position, under the action of gravity, and when this position is reached, a shot-pin 84 on lever 85 enters a hole 80 in sliding block 70 to allow actuation of clutch-engaging lever 100. In further modifications, the guard is moved to its guarding position under the influence of spring, pneumatic or electromagnetic means.

Abstract: 502,360. Coating metals. NETTER, L. Sept. 15, 1937, No. 25104. Convention date, Sept. 16, 1936. [Class 82 (ii)] Coloured coatings are produced on zinc and galvanized articles by treating the articles in a bath of heavy metal salt and then in a bath containing molybdic acid or a molybdate. The molybdate bath may contain small additions, e.g. 0.25 per cent, of heavy metal salts. The first bath contains salts of nickel, copper, cobalt, &c., e.g. it may consist of a solution of 10-15 per cent copper or nickel sulphate and 1 per cent acetic acid; the treatment may be effected with or without the use of electric current. When electric current is used the zinc &c. article is made the cathode. This treatment is stated to give a coating of heavy metal or heavy metal compound. The molybdate bath is preferably neutral or slightly acid and, to prevent sludge deposition, a buffer agent may be added. Suitable buffering agents are sodium acetate and acetic acid, sodium tartrate and tartaric acid, glycocoll and hydrochloric acid, sodium citrate and hydrochloric acid. Examples of suitable baths contain (a) 0À5-5 per cent of ammonium molybdate and 0À1-0À5 per cent of tartaric acid, (b) 0À5-5 per cent of ammonium molybdate alkalized with ammonia and set to a pH value of 5 by a buffer solution of sodium acetate and acetic acid.

Abstract: 785,714. Automatic speed control systems. BRITISH TELECOMMUNICATIONS RESEARCH, Ltd. Aug. 30, 1955 [Sept. 1, 1954], No. 25427/54. Class 38 (4). The speed of rotation of a magnetic recording drum is maintained constant by feeding signals of a frequency proportional to drum speed to a sharp cut-off filter whose output controls an eddy current brake associated with the drum motor and whose cut-off frequency corresponds to the desired constant speed. Amplified signals from a reading head, associated with a track on the drum carrying a periodic trace such as a sine wave, are applied to a low-pass filter LPF whose amplified output is applied over rectifiers MR1, MR2 and a resistance-capacity network R1, C1 to the grid of a valve VT. The negative part only of the filter output thereby determines the negative grid bias of the valve which remains non-conducting until the desired speed, corresponding to a point on the steep attenuation curve of the filter, is approached. Thereafter, small speed deviations from the desired value cause variations in filter output and grid bias, whereby the valve output over lines 12, 13 to the energizing coils of an eddy current brake, associated with the electric or other motor driving the drum, is correctively varied to restore the speed. A high-pass filter may replace the one described in which case the positive part of the filter output controls the valve.
