Patent GB-190101969-A (GB)
Inventor: WILD WILLIAM
Filed: 1901-01-29
Granted: 1901-03-16
Abstract: 1969. Wild, W. Jan. 29. Kettles, pans, etc.; lids and covers.-The lid a of a domestic pan, kettle, or other utensil is made of dished form, with an aperture c, which is normally closed by the light cover d. The spindle e, e<1> of the cover d works loosely through holes in the bridge-pieces f, g, fixed to the cover a. The bridgepiece g serves also as a handle for the cover a. When the contents boil, the steam raises the cover d and escapes through the aperture c. The violence of the ebullition within the aperture c is checked by the bridge-piece f serving as a baffle, the tendency of the contents to rise through the aperture being thereby reduced. Any of the contents rising through the aperture into the cover a either evaporates or flows back into the vessel.

Title: Improved Process and Apparatus for Manufacturing a White Sulphate of Lead Pigment
Inventor: HANNAY JAMES BALLANTYNE
Filed: 1901-02-01
Granted: 1902-01-30
Abstract: 2297. Hannay, J. B. Feb. 1. Calcining-furnaces; fumes, treating.-Lead sulphide ores are directly burned to lead sulphate, for the production of a white pigment, in the furnace a, consisting of a basic-lined cylinder b, having an iron plate bottom c on which is placed a layer of coke breeze d, above which is a pile of coke slabs e. Three tuyÞres f enter below the coke surface, and other air inlets g, hare provided above it. A conveyer m feeds the galena in small quantities to a plate n in an inclined conduit j, whereby the galena is thrown off and distributed evenly in the furnace. A chimney o and damper p are provided for use when starting the furnace before the galena is introduced. When the furnace is heated and the process started, the galena fuses and drips over the coke slabs, thereby largely protecting the coke from combustion. The interior of the furnace is kept at a pressure below that of the atmosphere by means of a fan q. The sulphide burns in the same way as melted material from a wick, and forms basic lead sulphate which passes with the excess of oxygen through the outlet i past a damper 5. The sulphide is used in excess, and this excess collects with the slag and gangue on the coke breeze, taking up all the silver and other foreign metals in the ore in its descent. The fumes pass to a dust-collector r, from which they pass to a cooler s. The collector and cooler have doors t for removing deposited matter. The cooler consists of long vertical iron boxes from the interiors of which the fume may be detached by striking the outsides. The undeposited fume is drawn by the fan q and delivered to hoppers u, above which are a number of flannel-cloth bags v through which the air and other gases are drawn by a fan, leaving the sulphate on the surface thereof. This sulphate is shaken off the bags by oscillating one or more handles &c. 2, each of which is connected to the supporting plate of a row of bags.

Title: Improvements in or relating to Compressed Air Railway Breaks.
Inventor: PASS ERNEST DE
Filed: 1901-08-13
Granted: 1901-11-23
Abstract: 16,265. De Pass, E., [Soc. Anon. des Freins " Stop "]. Aug. 13. Brakes, compressed-air. Each vehicle is fitted with a pressure-reducing accelerator, while a special valve on the engine ensures the simultaneous application of the brakes. Fig. 1 shows an accelerator. The diaphragm c is attached to the perforated cylinder e, into which is screwed the spindle f, which has a valve g communicating with the atmosphere, a loose valve i, and a counterbalance piston h of the same area as the valve g. In pumping up the train-pipe d, the valve i lifts until the pressure is the same on each side of the diaphragm c, while venting the pipe causes the diaphragm, cylinder e, and rod f to fall rapidly, to compress the spring p and open the valve g for a brief period. Each accelerator transmits to the succeeding one a definite reduction in pressure, until, when the last vehicle is reached, the pressure in the train-pipe is sufficiently reduced to apply the brakes throughout the train. Fig. 3 shows the driver's valve, the plug 2 of which has a port 1, which may communicate through the channels d<1>, x, y, or z with the train-pipe, reservoir, atmosphere, and the pressurereducing regulator respectively. The regulator comprises a screw pointer 5, worked by the handle 6, Fig. 2, which controls a passage 7 leading to the atmosphere. The handle 6 traverses two concentric graduated circles, the inner one indicating the number of coaches in use, and the outer one showing in grammes the corresponding initial reduction in pressure. The driver sets the handle to read off the necessary reduction of pressure for the number of coaches in the train, and the driving-valve is operated to cause this minimum fall in pressure, while the maximum reduction of pressure effected after the complete application of the brakes is shown by a gauge.

Title: Improvements in Apparatus for Raising Liquids by Means of Steam, Compressed Air or the like
Inventor: SCHOLL ALBERT
Filed: 1902-03-01
Granted: 1903-02-26
Abstract: 5212. Scholl, A. March 1. Direct air or steam pressure apparatus for raising acids and other liquids. The supply of pressure fluid and its exhaust are controlled by a bell 15 partially immersed in mercury or other suitable liquid 14. The underside of the bell communicates through the passages 19,20 with the pressure chamber 4, and through a valve opening 16 and chamber 12 with the pressure medium pipe 9, and its upper side through a valve opening 21 with the atmosphere, and through the small opening 23, passages 22, 27, and pipe 17 with the pressure chamber. The bell 15, when in its upper position, closes the opening 21 and opens the opening 16, the reverse taking place when the bell is in its lower position. In operation, the liquid runs into the chamber 4, expelling the air through the outlet 21, until it reaches the pipe 17. Air is then compressed in the space 20, which is annular, surrounding the pipe 17, thus raising the bell 15, and opening the supply of compressed air &c. from the pipe 9. Owing to the small section of the opening 23, the pressure above the bell remains less than that below, and the bell is held in its raised position till the liquid level reaches the lower end of the pipe 3. By adjusting the position of the lower end of the pipe 17, the pressure period and the quantity of liquid discharged can be determined.
