Patent GB-189809210-A (GB)
Title: Improved Stove Regulator.
Inventor: WINTER ROBERT
Filed: 1898-04-21
Granted: 1899-03-25
Abstract: 9210. Winter, R. April 21. Draught, regulating.- Relates to a combustion-regulating device. The apparatus comprises a casing w closed at its lower part by a base piece w<1> and at its upper end by a top w<2> having an exit w<0>. A cylinder h is affixed to the top, and is surrounded by a cylindrical damper g. Both of these parts are provided with slits, so that, by moving the damper g by means of the handle e, the opening into the cylinder h from the air chamber a may be regulated. Openings are provided in the wall w of the air chamber a which are closed by valves k. In the wall of the smoke chamber j a hole is provided for the smoke pipe b. The opening w<0> is connected to the pipe b. When the slits in the cylinder h are closed, the chimney acts only upon the stove. When the draught is too strong, the damper g is moved so as to open the passages into the cylinder h. The partial vacuum created by the escaping gases causes the valves k to open and air to enter, which cools the gases, thereby reducing the draught. To better utilize the heat of the exhaust gases, apertures o are formed in the upper part of the casing w and are fitted with dampers n provided with teeth n<1> which engage teeth g<1> on the damper g. When the damper g is closed, the dampers n are opened, and this allows the air in the neighbourhood of the smoke chamber to be heated and escape through the openings o, fresh air being supplied through the valve k.

Granted: 1898-11-19
Abstract: 15,396. Baumgarten, D. L. July 13. Acetylene.- Fig. 7 shows a vertical section of one form of generator. The water tank 8 has a funnel-shaped bottom connected by a neck 9 with the box 11. Communication may be cut off by means of the valve 28 actuated by the lever 33. The carbide is carried in buckets 18 on an endless belt 17 running on pulleys 16. The lower pulley axle carries a toothed wheel held by a detent which is released by the descent of the gas holder 12, to allow the endless belt 17 to move down under the weight of the carbide, till the lowest bucket 18 is inverted and discharges its carbide down the funnel 14, where it falls upon and opens the balance valve 24 and passes down the chute 13 to the box 11. When necessary, the box 11 may be emptied through the discharge pipe 29, and the amount of water thus lost may be made up by adding fresh water through the funnel 34. Several modified methods of controlling the discharge of carbide are described ; in all of them the carbide is carried in a series of horizontal travelling carriages, or in the compartments of a larger carriage, and the motion is obtained or governed by means of a pawl and ratchet-wheel or a toothed wheel and rack suitably actuated by the motion of the gas holder.

Patent GB-189920026-A (GB)
Title: Improvements in Striper-attachments for Circular Knitting Machines.
Inventor: SULLIVAN DANIEL FRANCIS
Filed: 1899-10-05
Granted: 1899-11-11
Abstract: 20,026. Sullivan, D. F., and Cawley, J. A. Oct. 5. Circular knitting-machines.-A number of threadguides 20, 21, for striping purposes, are pivoted to the upper end of levers 15, &c., and have slots working on a fixed pin 17. These levers are pulled to the left, Fig. 2, by springs z, and their heels rest on levers k pivoted at m. Spring- actuated latches q normally hold down the left ends of the levers k, and so hold the thread-guides out of action. A cam f on the cylinder acts on a roller g, and at every revolution moves a slide a to the left, against the action of a spring i ; the pawl h thus turns the ratchet-wheel P one tooth. Fixed to the ratchet-wheel is a pattern wheel having pins j, j<2>, which act on noses s, t on the levers k and on iutermediate unlatching levers l. When the last course of any particular colour is nearly finished, a pin on the pattern-wheel acts on an unlatching lever, which presses against and removes the corresponding latch q, allowing the spring z to draw a new yarn into action. An inverted landing-wheel keeps the thread below the beards until it is taken by the looper wheel. After a short interval, a pin on the pattern ring depresses a lever k until it is latched by a latch q, thus lifting the first thread-guide out of action. The thread 22 now passes over a pin 37 on a fixed shear blade 35, Figs. 5 and 6, and passes to the back of a cutter wheel 30, which is rotated by the contact of its blades with the finished work, as shown in Fig. 4. The rotation of the wheel causes the thread to be sheared against the fixed blade. A loose end is left on the fabric, but the free end of the yarn comes in contact with some ravellings placed behind the wheel 30 ; these ravellings hold the end of the yarn by friction until it is again put into work. The wheel 30 works on a fixed pin 26 carried on a support fixed over a gap or depression 23 in the push-down G.

Title: Thermal Storage Apparatus in connection with Steam Boilers.
Inventor: HALPIN DRUITT
Filed: 1901-07-20
Granted: 1902-06-05
Abstract: 14,823. Halpin, D. July 20. Steam receivers ; feedwater, heating and supplying.-Relates to "thermal storage apparatus" of the kind described in Specifications No. 20,203, A.D. 1891, and No. 363, A.D. 1892. The steam space of the storage reservoir b is connected to the steam space of the boiler by a large tubular conduit, through which passes the pipe e for conducting heated feedwater, which has accumulated in the reservoir, into the boiler. The feedwater is supplied to the reservoir by the pipe c, and becomes heated by falling through the steam thetein. Its transfer to the boiler is controlled by the valve f. When the boiler has to be forced, the supply of water by the pipe c is stopped, and the water already in the reservoir becomes more highly heated, so that. on transfer to the boiler, it evaporated more readily. In the arrangement shown as applied to a locomotive, the tubular connection d takes the place of the ordinary steam dome, and serves also for the passage of the steam pipe g. The application to Lancashire and marine boilers is illustrated in the Specification, the details of the apparatus being suitably modified.

Title: Improvements relating to the Production of Hydrocyanic Acid.
Inventor: FELD WALTHER
Filed: 1901-12-06
Granted: 1902-12-04
Abstract: 24,920. Feld, W. Dec. 6. Hydrocyanic acid.-Relates to the production of hydrocyanic acid by distillation from matters containing iron cyanides, for example, gas-purifying materials, Prussian blue, ferrocyanides, ferricyanides, and the like, whether soluble or insoluble. Consists in boiling the neutral or acid cyanogen compounds with a mercuric compound, such as mercuric chloride. The reactions are illustrated by the following equations- The cyanide of mercury thus produced is then decomposed by distillation with an acid, and the hydrocyanic acid is absorbed in alkali hydroxide or the like. If the original material contains free acid, hydrocyanic acid is at once produced. If it is alkaline, it must be rendered neutral or acid, and preferably it is neutralized by admixture with a slight excess of a salt the hydrate oxide or carbonate of which does not precipitate metallic mercury, or mercurous or mercuric oxide, from mercuric solutions, for example, salts of magnesium, zinc, aluminium, and manganese. If insoluble iron-cyanogen compounds which are but slowly decomposed by mercury salts are present, they are rendered soluble by treatment with caustic alkalies, or earth alkalies, or the like, after which the alkali is neutralized by one of the salts above mentioned. In order to regenerate the acid mercuric solution, which remains after the distillation, an oxidizing-agent, such as bleaching-powder, is added,wherebythe protochloride and any sulphide of mercury present are converted into mercuric chloride. The iron compounds may then be precipitated by addition of hydroxide of calcium, magnesium, or the like.

Title: Improvements in connection with Regulating Apparatus and Fittings for use with Steam Superheaters.
Inventor: OGDEN JOHN EDWARD LEWIS
Filed: 1902-02-05
Granted: 1902-12-18
Abstract: 2963. Ogden, J. E. L. Feb. 5. Superheaters, steam. - Relates to thermostatic apparatus for regulating the temperature of superheated steam by admitting a variable quantity of wet steam to mix with it, by returning some of it to the boiler, or delivering a portion to another boiler, or by supplying a blast of air to cool the superheater. Fig. 1 shows one form of apparatus arranged to control the proportions of superheated and wet steam supplied to the engine. It is connected to the superheater a, and to the boiler direct at b; d is the steam pipe. A portion of the superheated steam enters a small trumpet-mouthed pipe p and passes through an expansion tube q. The movements of the end of this tube, in accordance with the varying temperature of the steam are communicated, through the links and levers shown, to a cylindrical grid valve f, which diminishes the supply of superheated steam as the temperature rises. The deficiency is made up by wet steam entering through the valve x, which is pressed to its seat by a light spring, but is otherwise free to rise. Fig. 2 shows a modification in which the expansion of the tube q acts to operate a valve 6 which controls the admission of wet steam through the pipe 8 and branch 4, to mix with the superheated steam passing along the pipe 2. In this case, the expansion tube q is fed with superheated steam through the pipe 5. Fig. 4 shows one form of apparatus for cooling the superheater by an air blast. The thermometric device q, which is similar to those above described, acts by means of a valve 15 to control the supply of steam to a nozzle 16 by which an induced blast of air is delivered at 18 to the superheater tubes 12. The air may be drawn in by the furnace draught through a valve under the control of the thermostatic device ; or any suitable means, such as a steam engine controlled by a valve similar to the valve 15, Fig. 4, may be employed, to project the air against the superheater. Fig. 7 shows an arrangement, applicable to a battery of boilers of the Lancashire type, whereby an excess in the temperature of the superheated steam delivered from any one superheater causes the return of some of this steam into one or more boilers the pressure in which is less than that of the superheater in question. The thermostatic device 33 operates a valve 32 which admits some of the steam at the excessive temperature to a pipe 36 from which branches 37, fitted with non-return valves, lead to the various boilers of the battery.
