Title: A process for desulphurising pig iron in the reduction of ore in a rotary furnace
Inventor: JOSEFSSON ERIK ANDERS AKE
IPC: C21B11/06
Filed: 1965-07-09
Abstract: Iron ore low in phosphorus together with slag former and coke is charged to a furnace rotating about an axis which is horizontal or inclined at not more than 45 DEG  thereto, oxygen-rich gas being introduced to the furnace to burn the carbon monoxide evolved. The conditions are such that due to the presence of a thick layer of coke the iron oxide content of the slag corresponds to not more than 3% of iron, while the temperature of the slag layer is above 1400 DEG C., whereby a low-sulphur iron is produced.  This process may be preceded by a similar process in the same furnace using a high-phosphorus ore, the conditions being such that the slag has an iron oxide content corresponding to at least 3% of iron and a temperature not greater than 1450 DEG C. to produce a bath of metal low in phosphorus.  The slag produced in this step is removed prior to commencement of the desulphurizing step.

Title: Improvements relating to lever units for time controlled apparatus
IPC: G04C23/34
Filed: 1956-09-27
Abstract: 878,444. Time switches. VENNER Ltd., and HORGAN, W. F. Sept. 26, 1957 [Sept. 27, 1956], No. 29604/56. Class 38 (5). [Also in Group XXIV] A lever unit 17, especially for co-operation with the hands 5b to 5f of a timer dial 4 of a time switch, comprises a pair of plates 22, 23 on a pivot 19 and carrying a pin 24 which serves as the pivot for a lever 29. The pin 24 and a pin 30 on lever 29 extend through a slot 34 in a second lever 32 which has a slot 33 through which passes pivot 19. Lever 32 has a pin 36 passing through a slot 37 in plate 23 and connected by a spring 39 to the lever 29 to urge the lever 32 to the right (Fig. 3). When the lever 32 is in this right-hand position, the pin 30 engages the end 48 of slot 34 so that if a pin 31 on lever 29 is engaged by a hand of the dial 4, the unit is rocked clockwise to the dotted position in Fig. 2. Thus a pawl 27 carried by the pin 24 moves a ratchet-wheel 28 on a camshaft 21a one step. The lever unit is returned by a spring 25a to the full line position (Fig. 2). If the lever 32 is in its extended left-hand position, Fig. 3, the pin 30 is opposite a lateral arcuate part 47 of slot 34 so that movement of lever 29 by a hand is not communicated to lever 32 and the cam-shaft 21a is not stepped on. As shown, two lever units 17, 18 are arranged one above the other, and the inner and outer location of levers 32 is determined by a selector member 11 similar to that of Specification 838,218. The cams 16 of member 11 bears on levers 57, 58 in turn acting on levers 51, 54 respectively engageable with the ends 35 of the levers 32 to project them to the left (Fig. 3) on desired days. A similar member 10 acts through levers 71, 78 to move fixed contact springs 68 away from a stop 70 and out of reach of contacts 66 which are controlled by cams 20 on shaft 21a. Members 10, 11 are driven by a gear-wheel 8 stepped round by a hand 5a on dial 4.

Title: Improvements in the production of textile and other articles from acrylonitrile polymers
Inventor: DOWNING JOHN
IPC: D01F6/18
Filed: 1950-12-05
Abstract: Artificial filaments, films, and other articles are obtained by shaping a solution of a fibre-forming acrylonitrile polymer, e.g. by extrusion or casting, and coagulating it by means of a liquid carboxylic ester of boiling point above 250 DEG C.  The acrylonitrile polymer may be polyacrylonitrile itself or a copolymer of acrylonitrile with another vinyl compound, the acrylonitrile being the predominating constituent.  The ester used as coagulant may be dimethyl phthalate, di-n-butyl phthalate, diamyl phthalate, di-hexyl phthalate, di-n-octyl phthalate, di-(2-butoxyethyl) phthalate, di-n-butyl sebacate, tri-ethyl citrate, di-n-butyl tartrate, triacetin, amyl benzoate, or 1:3-butylene glycol dibenzoate.  The spinning solution may be made with nitromethane as the principal solvent, e.g. with a mixture of nitromethane and water, or of nitromethane and formic acid, with or without water, or of nitromethane and resorcinol or catechol.  Alternatively, the solvent may be dimethyl formamide, propiolactone, butyrolactone, valerolactone, m- or p-nitrobenzene, nitroethanol, a nitropropanol, tetramethylene cyclic sulphone, ethylene cyanhydrin, or a composition comprising di- or polyhydric phenols but not nitromethane.  The temperature of the spinning solution may be room temperature or higher, e.g. 25-50 DEG C.  The coagulating liquid may be at, or below, or above room temperature, e.g. 10 DEG -95 DEG C.  The coagulating liquid may travel in the same or opposite direction to the extruded filaments.  Filaments or films may be stretched, e.g. in hot water or while passing over heated metal surfaces.  The stretched filaments may be allowed to shrink in order to increase their extensibility, e.g. by heating them to 140 DEG -200 DEG C. in the absence of tension or under tension insufficient to prevent shrinking.  Filaments and films may be heat set by heating them at 100 DEG -160 DEG C. at constant length.  In an example, a hot solution of polyacrylonitrile in a mixture of nitromethane and water is extruded into a hot bath of di-n-butyl phthalate.  The filaments obtained are stretched while passing over a metal plate heated to 140 DEG C., and are then heated at constant length at 110 DEG C. for 30 mins.  They are subsequently washed with acetone or petroleum ether. Specifications 690,553, 712,983, 712,986, 712,998, 712,999 and 713,000 are referred to.
