Patent GB-189809954-A (GB)
Title: Improvements in Gas Producing Apparatus.
Inventor: TAYLOR MAURICE
Filed: 1898-04-30
Granted: 1899-03-11
Abstract: 9954. Taylor, M. April 30. Gas-producers.-Relates to gas-producing apparatus, for use without a gas holder, in which the quantity of gas generated is automatically limited to the requirements. The gas is drawn from the producer, through a scrubber, by a pump or fan, the suction valve of the pump, or a valve in the suction pipe of the fan, being controlled by means of a gas bag so as to prevent or reduce the withdrawal of gas after the pressure of the discharge has risen owing to an excess of supply over demand. The supply of steam to the producer is regulated in the same way. The producer consists of a metal chamber, as shown, lined with fire-resisting material and fitted with a bottom door 4 secured by bent levers 6, 6, carrying screws 7, 7. The casing is formed with an annular space 8 to which steam and air are supplied, and an annular superheating-passage leading from this space to the space above the door 4 is formed by a casing 10 which is supported on pins 11 projecting from the door. The gas generated is led away at 14 through a jacketed, pipe (not shown) to the scrubber, whence it is withdrawn, in the arrangement shown in Fig. 1, by the pump 22 and delivered through the gas bag 28 direct to the supply main 38. The jacket of the pipe conveying the gas to the scrubber forms a steam generator or vaporizer which is fed under the pressure of the head of water in a U-shaped pipe. Steam and excess of water is withdrawn through another, smaller, U -shaped pipe, and delivered at the air inlet of the space 8, the pressure being limited to that due to the head of water which may accumulate in the bend of the pipe. The suction valve 25 of the pump is held open by the T-shaped lever 32, and, when the pressure in the gas bag 28 exceeds a certain limit, the bag, in expanding, acts on a hinged plate 35 connected as shown to the lever. A valve 33, controlling the steam supply, is at the same time partly or entirely closed. To prevent leakage of gas, the cylinder of the pump is formed with a groove 30, which is always covered by the piston and which is in constant communication with the suction pipe. When a fan is employed to draw off the gas, the arrangement shown in Fig. 4 is adopted. In this case the expansion of the gas bag acts to close, more or less, a valve 40 in the suction pipe of the fan 39, the steam valve 33 being operated as before. The fan is enclosed in a chamber 42, which is open to the suction pipe and is thus below atmospheric pressure, so that leakage is prevented.

Title: Improvements in Apparatus for Generating Acetylene Gas.
Filed: 1898-07-04
Granted: 1898-08-13
Abstract: 14,713. Lake, H. H., [Cie. Continentale d' Incandescence et de Chauffage System Franck et Poitrimol.]. July 4. Acetylene.-A cylindrical generator A, containing water and having an outlet valve D, is connected by a tube E to the charging-apparatus. The pressure of gas in the cylinder is balanced by the water in a tube N, which connects it to an overflow. A tube S leads away the gas to a gasometer C. The charging-apparatus, in the form shown in Figs. 1 and 2, consists of buckets 0, containing carbide, and pivoted to a disc P on a rotatable axle G. The buckets are so pivoted that, on releasing catches H, which normally keep them upright, by causing the catches to engage a fixed cam J they overturn and discharge the carbide into the tube E. The axle G is rotated by a weight M, connected by a cord to a pulley K on the axle G. A forked lever L, which engages stops on the pulley K and prevents rotation, is operated on the descent of the gasometer by a tappet T secured to the bell, thereby allowing the rotation of the disc P and causing another bucket to empty into the tube E. In a modification shown in Fig. 3, the carbide is placed in cylinders O<1> open at both ends and resting on a slab P<1>. These cylinders are secured to a chain passing round drums K<1>, K<11> so that the rotation of the latter brings them successively over the open end of the tube E. A forked lever L', actuated by the gasometer, and a weight M<1> give a step-by-step rotation to the drum K<1> as shown.

Granted: 1899-07-01
Abstract: 18,283. Weber, C. O., Cross, C. F., and Frankenburg, I. Aug. 25. Cellulose tetracetate. - Cellulose tetracetate is produced on a large scale in a pure state by operating in the following manner :-An intimate mixture of equimolecular quantities of magnesium acetate and cellulose, preferably that obtained from cellulose sulphocarbonate, two molecular proportions of acetyl chloride, and about one molecular proportion of acetic anhydride, is made in a kneading-machine provided with a heating and refrigerating jacket, and, when the reaction commences, it is moderated and controlled by addition of a solvent for cellulose acetate. The solvent is added gradually, commencing with very small quantities and adding the further quantities only when each preceding one has been homogeneously incorporated with the mixture, the quantity added being sufficient to keep the temperature below 70‹ C. The solvents preferred are nitrobenzene and its homologues, including dinitro compounds, epichlorhydrin, and dichlorhydrin. The mixture is agitated at a temperature not exceeding 70‹ C. for three hours, and it is then poured into alcohol. The acetate separates in fine white flakes, which are filtered off, washed with warm alcohol, and filter-pressed. This product is broken up, freed from traces of solvent and magnesium salts, and finally pressed and dried at not exceeding 80‹ C.

Granted: 1899-11-18
Abstract: 1692. Maignen's Filtre Rapide and Anti-Calcaire Co., [Maignen, J. A.]. Jan. 24. Filters of large capacity; cleansing; filtering- media.-Asbestos, paper, wood, or mineral fibres, or powdered coke, charcoal, clinker, or other mineral powder are suspended in the water to be filtered, thus forming an inorganic filtering-layer on the sand or similar filter bed. The water is supplied by a trough C through valves D to transverse distributing-troughs E, or perforated pipes. The filtered water is discharged through pipes J, I and valves N to a trough H. The filter is sterilized, a section at a time, by sterilizing- liquid forced into it from a tank L hy a pump M' and pipes M and J, and afterwards allowed to drain back to the tank L The filtering-layer, when foul, is removed by washing it off by a hose Y carried by an attendant who sits in a carriage X running on rails W or the like. The wash water, containing the filtering-layer, flows off through valves U, V in pipes R into a chamber where it is separated for use again. In a modification, the hose carriage runs in succession between a series of vertical plates which are pivoted so that all can be turned simultaneously into a horizontal position to form a cover for the filter. Instead of being washed off, the filtering-layer may be allowed to dry, and be then rolled up and so removed.
