Granted: 1897-05-29
Abstract: 6198. Darling, O. March 9. Water supply.-A pump D, fitted with an air inlet valve 2 and communicating with the water main, forces water and air into storage tanks A, A<1> which supply the service pipes or mains E. Air is drawn from the tanks and forced into a receiver C at a pressure sufficient for fire-extinguishing purposes by an air compressor D'. The connecting- pipes between the receiver and tanks are fitted with reducing-valves 4 which are normally set to maintain a uniform pressure for house supply. In case of fire the reducing-valves are adjusted to allow air at the higher pressure to pass freely from the receiver to the tanks. The air compressor is supplied by an inlet pipe 5 on starting, and the different pipes are fitted with ordinary cut-off valves or cocks 1, 6, 8.

Patent GB-189718817-A (GB)
Title: Improvements in and in connection with Pumps.
Inventor: EDWARDS FREDERICK
Filed: 1897-08-13
Granted: 1898-11-12
Abstract: 18,817. Edwards, F. Aug. 13. Plunger pumps ; concussion, preventing.-The barrels of high-speed circulating and other pumps have valveless inlets, and outlets 5, with or without valves, which communicate with the inlet in all positions of the plunger. The inertia produced in the water during suction enables a suction valve to be dispensed with, and easy discharge is facilitated by tapering the end of the plunger. In a modification, inclined annular passages form the outlets into a common delivery passage provided with a valve at the top. In another modification, the inlet is at the top of the barrel and the valved outlet at the bottom, the plunger having a concave end. In all these forms the motion of the water through the pump is to a great extent continuous and in the same direction, so that shock is minimized. Pockets formed as shown at 14, Fig. 8, or by projecting vanes, may be provided in the inlet and outlet passages &c. to prevent back flow of water. Pump valves and valve seats.-To enable the pump to work at low speeds, suction and delivery valves may be used, carried on seats which may be withdrawn into recesses so as to leave a clear passage when desired. Fig. 11 shows a sea-inlet valve 24, which in the extreme positions of the spindle is a stop valve, while in intermediate positions it acts as an automatic suction valve.

Title: Improvements in and relating to Continuous Working Spirit Stills.
Inventor: DUNN JOSEPH EDWARD

Granted: 1898-04-16
Abstract: 2980. Dunn, J. E. Feb. 5. Distilling spirits. - Relates to columnar spirit stills, and consists of a special arrangement of the parts of the apparatus and of special trays for use in the still proper. Fig. 1 shows the general arrangement of the apparatus, which comprises the still A with trays C, C', the upper of which C' are of similar construction but of smaller area than the lower trays C. Above this is a rectifier D in which the vapours rise in zig-zag fashion through a series of closed drums f which are cooled by water flowing around them from pipes g to h, whereby the heavier vapours are condensed and flow back into the still, while the lighter vapours pass on to the wash heater E, which is divided into three chambers by tube-plates i connected by tubes i<1>. In the chamber k are a number of closed drums f*, arranged and constructed similarly to those f in the rectifier D. The wash enters by the pipe l, circulates around the drums f*, flows through the tubes i<1> into the chamber k', and thence passes through the pipe m into the still A. The vapours, after passing around the tubes i<1>, rise through the drums f* and pass away to the condenser F, while any condensation from them flows back into the still A through the pipe n. The construction of the trays C, C' is shown in plan view in Fig. 2, and comprises a number of concentric guide - plates c forming a series of channels which are absolutely blocked at one place by a partition c<1>, so that the liquid which has to traverse all the channels on its way from the feedpipe to the exit pipe is caused to flow in opposite directions in adjacent channels. Fig. 4 illustrates the hooded vapour pipes d' of the trays C, C<1>.

Patent GB-189809664-A (GB)
Title: Amalgamating Process and Apparatus.
Inventor: BLOUME LEON
Filed: 1898-04-27
Granted: 1899-04-01
Abstract: 9664. Bloume, M. Oct. 30, A.D. 1897, [date applied for under Sec. 103 of Patents &c. Act, A.D. 1883]. Amalgamating.-Relates to extracting gold and other amalgamable metals by a process whereby the total extraction of the metal is obtained, the essential feature consisting in causing the crushed ore to rise under pressure through a column of mercury. In Fig. 1 is shown a receptacle having iron side plates A and two sheet - iron partitions D, dividing the receptacle into three compartments, each of which is separated by partial metal partitions E into a larger central chamber F and two narrow side chambers H. The three compartments are closed at the bottom by wooden blocks C, and the chambers F at the top by wooden blocks G. In each chamber H are a number of iron triangular cross-bars a attached to vertical side uprights joined at the top by a bar e forming a handle. Each central chamber is provided with tubes J, I, and M, the latter leading to a conduit N. Upon the conduit is mounted a tube P leading, by means of the valve Q, to either one of the two receptacles R, R', each of which is provided with a float S, S<1>, connected to a vertical rod T which moves in front of an index V, V<1>. A lead plate i is connected to a positive pole, and the side wall A at k to a negative pole of a source of electricity. Mercury is charged into the central chambers F through the tubes I, and afterwards the crushed and sifted ore mixed with about ten times its weight of water is forced through the tube L, tube K, and tubes J into the same chambers, air escaping through the tubes I. Mercury is thereby forced under the bottom cases of the plates E, and up the chambers B in the zig-zag course indicated, while the excess of mercury passes by the tubes M, N, and P to the receptacle R or R<1>, from which it is withdrawn before the amalgamating process starts. The ore mixture is caused by the pressure to pass up the chambers H, the zig-zag course causing the intimate contact of the ore with the mercury. This contact may be increased by covering the bars a with a rough or hard body such as quartz or emery, or even by making the bars of emery. The liquid and gangues lighter than the mercury escape to the space above the blocks G, from which they flow away. The amalgamating process, which may be assisted by passing a current of electricity through the liquid, takes place principally in the chambers H. During the amalgamating process, the mercury increases in volume, and the excess passes to the receptacle R or R', where its amount is indicated by the index on the rod R or R<1> as the float rises. When nine tenths of the mercury has been removed by means of the receptacle R or R<1>, the process is stopped, and the remainder withdrawn through the cock 0. The ore may be forced through the apparatus by compressed air or steam instead of by water.
