Abstract: 1471713 Synthetic gypsum and magnetite KRONOS TITAN GmbH 15 Nov 1974 [14 Dec 1973] 49651/74 Heading C1A A continuous process for the production of course particle size gypsum comprises continuously adding Ca source material and acidic FeSO 4  solution to water at superambient temperature, maintaining the pH of the aqueous mixture from 1-6 and at a temperature of at least 80 C., retaining particulate gypsum until coarse particles are formed, when they are withdrawn as a slurry, dewatered, and dried. At least 60% of the generally acicular particles after fracturing and/or rounding off by centrifuging are greater than 200 mesh (Tyler) and preferably sized from 75-300 Á. The preferred Ca source is aragonite, but may be limestone or CaCO 3 ; the acid concentration is preferably from 4-30% H 2 SO 4 . In an embodiment, magnetite and additional coarse gypsum are obtained by feeding the supernatant liquor from the reactor, and a Ca source material, e.g. Ca(OH) 2 , to a second reactor, the pH being between 6 and 8, and the temperature at least 80 C. free-oxygen-containing gas is fed into the FeSO 4  solution (at least 90 C.) to form crystalline magnetite of up to 67% iron content.

Abstract: 1,244,838. Liquid cooled electric generators. PLESSEY CO. Ltd. (Westinghouse Electric International Co.). 25 Oct., 1968 [2 Nov., 1967], No.49837/67. Heading H2A. In an electric generator, e.g. for aircraft use, having rectifier elements 8 in a cylindrical shroud 7 coaxially in a cavity of the rotor b or its shaft 2, together with a cooling system wherein liquid, e.g. oil, is fed into the shroud through a stationary tube 12 extending with clearance through an axial bore 4 in the shaft to lead with a running fit into a bore 11 of a partition 10 extending across one end of the shroud the liquid after passing through the shroud and other parts of the rotor returning along an annular gap 9 between the shroud and rotor to a clearance gap 14 between a shaft bore 4 and the tube 12, the annular gap 9 is closed at the shroud partition end and inclined tubular passages 17 divert the gap flow to a chamber 18 encircling the tube 12 and having an annular outlet whose diameter is similar to that of the shaft bore 4 and which faces the bore. By this construction turbulence is decreased by causing the returning oil to adhere to the tube outer surface by Coanda effect. A modified plug, Fig. 2, not shown, also provides inclined passages (22) to discharge the oil from the tube 12 to the shroud 7.

Abstract: 1530820 Automatic control of particle beam devices CGR - MEV 3 Dec 1976 [5 Dec 1975] 50613/76 Heading G3R An arrangement, Fig. 3, for coupling a microwave frequency input signal from a generator G to a linear particle accelerator 3 so as to minimize reflected reactive energy includes a frequency adjusting device 12 controlled by a comparator 9 responsive to a reference signal Vr and a signal V proportional to a phase shift ## between the micro-wave input signal and the signal in the accelerator when a particle beam is present. The signal V is obtained by combining a signal V 1  extracted from the output from the generator G, and a signal V 3  which is produced by applying a 90 degrees phase shift to a signal V 2  formed by a loop 30 sampling the micro-waves present in the accelerator. The reference signal Vr may be derived from a system, Fig. 6, for controlling the beam intensity. The intensity is measured by an ionization chamber 15 producing a signal d which is compared 17 with a reference d n  to adjust the heating supply for the accelerator cathode 31. The error signal is also used to control a motor 21 which drives the setting potentiometer 10.

Leg 40 is completed by a rotarily knitted zone 42 knitted from a thicker yarn after which a tubular part is knitted by reciprocation having elastic, intermediate and crutch zones 43, 44, 45. Reciprocation then continues to form the waist opening T with elasticised zones 48 on either side and crutch and intermediate parts 46, 47. The tights are completed by knitting zones 45a to 42a and leg 40a to correspond to leg 40 and zones 42-45. In the panty portion, feeds 1G and 2G feed rubber yarn and feeds 3F and 4F feed normal yarn and by reciprocatory knitting it is arranged that fewer courses are knitted in the portion 46 than in portions 47, 48. In portion 48 elastic yarn is knitted in every fourth course by alternate needles and is held until the course of normal yarn after the next course of elastic yarn. Tilting selector jacks 4 each have two sets of frangible butts 8, 9 and a permanent butt 7 and cooperate with further jacks 5 each with a butt 11 to select needles 6 each having a butt 12. Patterning levers 16, 17, 18, 19 engage butts 8 to select needles at the four feeds during continuous rotation and forward rotation during reciprocation while levers 20, 21, 22, 23 engage butts 8 to select needles at the four feeds during reverse rotation. Selected jacks are restored to their initial position by cams 29 between feeds. Cams 15 lift the selected jacks to raise their associated needles to knitting level while movable cams 28 engage butts 9 to lift jacks so that their associated needles hold loops. Instead of knitting fewer courses in area 46, a tuck stitch fabric may be knitted in which stitches are held over a number of courses and the yarn of the intervening courses forms a number of tuck loops.

Abstract: 1,133,455. Cables. BRITISH INSULATED CALLENDER'S CABLES Ltd. 9 Dec., 1966 [10 Dec., 1965], No. 52549/65. Heading H1A. A high voltage, high power D.C. cable 1 has thermal insulation 8 to reduce the temperature gradient across the dielectric wall 4 (e.g. oil impregnated paper tapes or extruded plastics material). The thermal insulation may be a seamless sheath of cellular P.V.C. or other cellular plastics material or a tape of non-woven glass fibre reinforced by tape of either woven glass fibre or nylon &c. This insulation may be located outside a cable (7) (Fig. 3, not shown) in the form of a duct (15) (Fig. 3, not shown) embedded in concrete (17) in a trench (16), or it may be in the form of a non-hygroscopic granulated back-fill (12) (Fig. 2, not shown) (distillate of coal or cellular concrete) in trench (11) under soil (13). The said cable (7) may be of conventional construction except for the large central bore or it may be like cable 1. The thermal resistance between the dielectric and the ground may be 300 or 500-600 thermal ohms. A coolant, e.g. insulating oil is forced through central bore 2 and may penetrate the interstices of stranded conductor 3 to impregnate the insulation. Instead of or in addition to central bore 2 the external surface of the central conductor may have helical or longitudinal grooves for the coolant which may be water, and in which case an impervious barrier (e.g. lead or conducting polyethylene) separates the conductor from the dielectric. The invention also relates to multicore cables and to joints and terminations in single and multicore cables.
