Title: Improved Apparatus for Sterilizing Water.
Inventor: DESMAROUX JOSEPH
Filed: 1897-08-23
Granted: 1897-10-09
Abstract: 19,426. Desmaroux, J. Aug. 23. Liquids, sterilizing.- The apparatus for sterilizing water consists of a heater f, one or more temperature exchangers B, C, a temperature regulator g, and two flow regulators A, D. The water is first passed through a filter 9, thence through the flow regulator A, the temperature regulator g, the pipe 10, the first heat exchanger B, the second heat exchanger C, the pipe 12 to the bottom of the sterilizer, the outlet e, the pipe 13, the second heat exchanger C, the first heat exchanger B, the flow regulator D, and the outlet 15. The vertical boiler has a central uptake, surrounding which are a number of superposed annular water chambers a, having each an annular flange b dipping into a correspondingly-grooved seat on the other, the chambers being separated from each other by springs. Each chamber has an internal division to cause the water to circulate round each annulus before passing to the one above. The heat exchangers consist each of two sheet-metal plates, spirally coiled so as to leave narrow passages, within which pass the hot water to be cooled in one direction, and the cold water to be heated in the other. The flow regulators A, D, which ensure that the liquid shall remain in the apparatus the exact time to effect perfect sterilization, consist each of two casings at right-angles to each other, connected by ports, and each containing a spring piston. The upper casing has the inflow and outflow connections. The pressure caused by the sterilizing process acts upon the two pistons, so as to close in one case, and to open in the other, a free passage for liquid from the inflow to the outflow connections. The temperature regulator g only permits water to enter the first heat exchanger if the temperature in the sterilizer is sufficient. It consists of a chamber h in communication with the boiler, and containing a longitudinally-collapsable tube i inside a tube l filled with petroleum or the like. A rod j is attached to the bottom of the collapsable tube, and is adapted to lift up a water-supply valve k. As the temperature in the boiler rises, the liquid in the tube l expands and collapses the tube i, causing the rod j to open the valve k and admit water.

Patent GB-189823305-A (GB)
Title: Improvements in and relating to Apparatus for Raising Sewage and other Liquids by Direct Air Pressure.
Inventor: SHONE ISAAC
Filed: 1898-11-05
Granted: 1899-11-04
Abstract: 23,305. Shone, I., and Ault, E. Nov. 5. Direct air-pressure apparatus.-Relates chiefly to the air valves of apparatus described in Specifications No. 3524, A.D. 1878, No. 16,453, A.D. 1884, and No. 15,203, A.D. 1888. In order that a pair of "ejectors" may discharge alternately, and never simultaneously, the air supply to the two main valves is controlled by a third and somewhat similar valve. Each end of the casing of this controlling-valve communicates with one end of one of the main valve casings, which valves, as before, are actuated by air pressure on their ends, under the control of float-actuated slide valves. The position of the controlling- valve is thus determined by the state of the two "ejectors" conjointly. Fig. 3 shows one arrangement of valves &c. Air passes from the controlling-valve E by pipes F<1> to the two main valves D, only one of which and one "ejector" are shown. Air passes between the main valve and "ejector" by the chambers G<2>, G<1>, which are connected by a pipe F led up to some height and provided at its upper end with a strainer H for separating solid matter from the exhaust air. In a modification, the valves D and E are in one casing near the surface, the slide valves being carried on the ejectors." In another modification, three " ejectors " are used. In all cases the necessary stop cocks are fitted, so that one ejector can be put out of use for repairs &c. Fig. 9 shows one form of controlling-valve. It consists of two pistons connected by a rod and sliding in a liner E<5>. The covers have rings E' to limit the stroke of the valve. The four-way cock E<7> and its connections allow the valve E to be retained in one or other of its extreme positions. In a modification, in which the valve E is between the two valves D, the same object is effected by a slot in the rod E', widened at both ends and having a flat bar capable of being turned passed through it, this device also serving to limit the motion of the valve E. Fig. 10 shows the improved main valve used in the arrangement shown in Fig. 3. The casing is made so that it can be bored in one operation and fitted with a liner. The seating D' for the pistons is secured by screws or soft metal. In order to adapt the same main valve for right or left hand use, the setting on which the slide valve C<2> works is in the form of a liner C<6>, which can be turned end for end so that the hole C', Fig. 11, for the passage of air to the slide-valve casing may register with that one of the holes D<8>, D<8> which is in communication with the air supply. The standard G, Fig. 3, is also made reversible.

Abstract: 9718. Wilson, W. J., and Turnbull, H. C. May 9. Signals, lamp. -Relates to a projectile for producing and burning acetylene gas upon contact with water, and designed for naval and other purposes. The gas chamber C is separated from the carbide chamber B by a perforated partition D making frictional contact with the casing A, and is closed at the other end by a disc e, which carries the burners f, and a chamber g containing metallic potassium protected from oxidation by coal oil and a cap i. A fuze. consisting of a lead tube charged with powder, is coiled round a spirally-grooved plug F, to prevent premature ignition, and the ends of the projectile are protected by caps d, H until the projectile is required for use. Before firing, the caps d, H, i are removed, the coal oil is poured out of the chamber g, the end of the fuze is bent over into the chamber, and the loose cap G is replaced to protect the end of the projectile from the firing-charge. During the flight of the projectile, the cap G drops off, so that, when the projectile enters the water, the potassium ignites the fuze j<1>. The weighted end X then causes the projectile to assume the position shown in Fig. 7 relatively to the water line w. Water traverses the tube c to the carbide chamber B, and the gas, upon issuing from the burners, is ignited by the fuze. The expansion of the spent carbide causes the partition D to slide along the casing as indicated by the dotted lines.
