Title: Improved Filtering-apparatus for the Extraction of Liquid from Finely Crushed Minerals or the like.
Inventor: WEBB JOHN FREDERICK
Filed: 1904-04-14
Granted: 1905-04-06
Abstract: 8605. Webb, J. F. April 14. Travelling-band filters.-The apparatus is intended especially for extracting liquid from crushed minerals, and is constructed so that an intermittent vacuum is produced beneath separate sections of the band. The latter, which travels round drums B fixed to a frame C, Fig. 1, is shown in section in Fig. 3. The bottom a of the band is of rubber, above which is a grating of wooden bridges b supporting a layer of coco-nut matting d, and an outer layer of filtering-material e. Certain of the bridges are solid so as to divide the length of the band into sections. A flexible tube G, communicating with the grating spaces and divided into sections corresponding to those of the band, is attached to the side of the latter. The sections of the tube are connected to an exhaust receiver by flexible pipes H and a revolving plate K. The device for the connections is shown in Fig. 5. The ends of the tubes H are attached to a flange P on a sleeve P<1> revolving on the axis Q. Side connections H<1> unite the tubes with a plate S which revolves over a fixed frame R having three sections connected separately by exit pipes N to the exhaust, and a fourth by means of which the vacuum is intermittently released. The lower part of the band, passing through the sludge tank, is submitted to the action of the vacuum, and the solution is drawn through to one of the exits N, while the sludge adheres to the band. The sludge on the section which has left the tank is washed by water distributed over it from the pipes M, the water being drawn through to a second of the exits. To the third exit is drawn moisture from the sludge, which is dried on the descending portion of the baud. The vacuum is released and the dried material leaves the band just before it is about to re-enter the tank. The band is driven from the pulleys F by means of a pinion on the inside of one of the: drums B, and the moving portion of the central device is rotated by means of a telescopic rod B', attached to the band and to the flange P. Rollers D pivoted on bars E support the bands at points between the drums.

Patent GB-190412850-A (GB)
Title: Improvements in connection with Steam Controlling Valves.
Inventor: NESBIT DAVID MEIN
Filed: 1904-06-07
Granted: 1905-06-01
Abstract: 12,850. Nesbit, D. M., and Clowes, W. June 7. Actuating valves and cocks; valves and cocks for automatic liquid supply; tampering with valves and cocks, preventing; casings.-Relates to valves for controlling the supply of steam or other fluid to radiators and the like in heating-systems, and for other steam-employment purposes, such as steam traps. The valve is actuated by a pivoted member, the movements of which are controlled by a thermostat. Fig. 1 shows the valve adapted to a system of radiators for the circulation of steam or other heating-fluid. The steam enters by way of the branch d and passes through the outlet branch e into the pipe f, and thence into the radiators. The supply of steam is controlled by the valve a. The valve opens under steam pressure, the opening being facilitated by the spring h. The valve is controlled by the arm or arms i which are attached to a disc k pivoted on the casing by a screw pin l. As the apparatus is adjusted by screwing the pin, tampering may be prevented by the use of a cover t, as shown, but, if required to be adjustable from the exterior, the pin may be passed through a suitably-packed opening in the cover. The disc k is actuated by the iron rod o, which is enclosed in a copper tube r. The iron rod and copper tube are rigidly connected at q. The rod has a narrow neck s to render it sufficiently flexible. An ordinary hand-operated stop-cock g permits of the radiator being cut out when other parts of the heating-system are in use. When the temperature of the radiator is above the normal, the end q of the rod has been moved a greater distance to the left than it has been expanded. This is due to the greater coefficient of expansion of the copper. The disc k rotates counter-clockwise and the valve is forced into its seat by the arms i. As the temperature falls, the reverse action takes place, the arms are raised and the steam again forces the valve open. In a modification, the valve may be opened against the steam pressure by placing the fulcrum of the disc on the upper side of the casing, remote from the valve. The disposition of the various parts may be varied to snit the particular heating-system used.
