Title: Improvements in the manufacture of pig and cast iron
IPC: C21C1/02
Filed: 1941-07-26
Abstract: 550,927. Purifying iron. BRITISH CAST IRON RESEARCH ASSOCIATION, PEARCE, J. G., and MORGAN, E. July 26, 1941, No. 9523. [Class 72] The silicon and phosphorus contents of molten pig or cast iron are reduced, without materially affecting the carbon content, by bring- ing into intimate contact with the molten iron a fluid oxidizing slag composed of lime, a mixture of iron oxides (FeO and Fe 2 O 3 ) and a fluxing agent such as fluorspar, and which is free from silica except for any present as impurity. The lime content does not exceed 40 per cent. by weight and the iron oxide content is not less than 60 per cent. In examples, slags contain 2 parts lime, 30 parts millscale and 2 parts fluorspar or 10 parts lime, 50 parts millscale or haematite ore and 2 parts fluorspar. The amount of slag employed does not exceed 20 per cent. of the amount of iron employed, the amount preferably being 12-15 'per cent. The materials for making the slag may be added in the cold condition, being added after the molten iron has been poured into the reaction vessel, and the whole churned up mechanically or by bubbling a gas such as carbon dioxide under pressure through the melt.
Patent GB-295411-A (GB)
Title: Improvements in and relating to the drying of fuel gases
IPC: C10K1/10
Filed: 1927-04-07
Abstract: 295,411. Cooper, C., Henshaw, D. M., and Holmes & Co., Ltd., W. C. April 7, 1927. Drying gases.-In the drying of fuel gases and particularly town gas by contact with liquid absorbents, the rate of withdrawal of the liquid from the drying apparatus and its rate of return thereto are maintained substantially constant during a complete sequence of diurnal or like cyclic variations in production or consumption so that the average concentration of the liquid and the moisture content of the gas remains substantially constant. Thus, for example, the moisture content of the gas should never be such that moisture accumulates in the mains, any moisture deposited during a part of the cycle being evaporated during another part. The moisture expelled from the liquid during reconcentration may be controlled by varying the heating-surface in the reconcentrator. The liquid may be circulated by a pump through a tank, cooler and a drying-chamber such as a brush washer, a portion of the liquid being byepassed through a reconcentrator to the tank.

Abstract: 1,253,517. Mixing apparatus; roller-and-ring mills. ACHESON INDUSTRIES Inc. 7 Feb., 1969 [28 Feb., 1968], No. 9717/68. Headings B1C and B2A. Apparatus for mixing, grinding and dispersing has a tapered pan 2 and at least three polished, rough or fluted tapered rolls 6, 7, 8 each of which mates with two other rolls or with one roll and the side wall of the pan. The rolls are carried in a yoke 5 and the pan and yoke are relatively rotatable; as shown, the pan rotates on a turntable 3. Both rolls and pan (or yoke) may be driven as shown, or one may be driven and the other rotate idly. The yoke and rolls may be raised by a hydraulic jack 9, 10; an adjustable abutment (52, see Fig. 5 not shown) enables the nip or loading between the rolls and pan sidewalls to be varied and the rolls are vertically adjustable (see Fig. 4, not shown) to vary the nip between them. The shafts and rolls are hollow for circulation of a heat exchange medium. Scrapers may be provided. The preferred taper angle is 12-18 and the rolls will move at the same linear speed only on a single contact line, slip, and shearing of the material, occurring elsewhere. If there be more rolls than three they may be spaced round the central roll, see Fig. 6 (not shown); other numbers than three (e.g. seven) could be arranged diametrically. In a modification for continuous treatment the rolls 60, 61, 62, Fig. 7 are arranged horizontally in a closed container 59 with inlet and outlet shoots (78, 79, Fig. 8 not shown) in opposite ends.

Date Jun. 13, 1991.A passive optical network includes a head-end station and a plurality of terminations. The terminations are responsive to control signals from the head-end station. The head-end station is arranged to receive frames having a predetermined bit rate and comprising signals transmitted by the terminations. Ranging pulses are transmitted from each of the terminations to the head-end station where the received ranging pulses are sampled at a high sampling rate greater than the predetermined bit rate. The data samples are applied to a processor which determines the phase and amplitude of the ranging pulses and generates control signals for the terminations to modify the phase or timing and amplitude of the transmissions from the terminations. A locally generated marker pulse may be applied to the incoming data frame before it is sampled in the head-end station, the marker pulse providing a phase and amplitude reference for use by the control processor.
