Patent GB-189922028-A (GB)
Title: Improvements in or connected with Electrodes for Electrolysers.
Inventor: EYCKEN RAPHAEL
Filed: 1899-11-03
Granted: 1900-04-07
Abstract: 22.028. Eycken, R., Leroy, C., and Moritz, R. May 23, [date applied for under [Sec. 103 of Patents &c. Act, A.D. 1883]. Chlorine ; hydrogen; oxygen.-Relates to electrodes suitable for use in electrolysing alkalinechloride solutions. The electrodes are of two kinds, (1) those formed of materials capable of being cast, moulded, or shaped easily, and (2) those formed of other material, such as carbon. Each class is formed of two parts, (1) the base or carrier, and (2) the electrode. In the first class, the base consists of a plate a, Fig. 12, with a smooth rim, and with a deep cross-groove or canal at the top and at the bottom, joined by rows of furrows m of any shape in cross section. The electrolyte enters the bottom canal, passes through the furrows, and leaves by the top canal. This base may be a good or bad conductor. When the electrolyte is to be heated, a pipe coil is embedded in the mass of the plate ; or hollow plates may be used. The electrode itself is a wire netting g, or a corrugated or perforated sheet or steel plate. If the wire netting has thick wefts, the furrows may be omitted, Fig. 7<b>. The base may be a cast-iron rim or frame a', Fig. 5, enclosing a piece of corrugated metal r<1>, which takes the place of the furrows and upon which the wire netting is placed. The canals are in this case formed in the frame. In the second class, the base consists of an insulated or insulating frame, with holes in the top through which thick carbon rods c, Fig. 12, are passed downwards nearly to the lower member of the frame. Openings are provided for the admission and discharge of the electrolyte. The electrode itself consists of thin carbon rods 10 of round, polygonal, or other cross-section, held by means of asbestos fabric in contact with the thick rods. They reach from the bottom member of the frame nearly to the top one. The electrodes of both classes may be constructed with only one active face, or with two active faces. They may be formed cylindrical, prismatic, or of other shape instead of flat. To form a cell such as that shown in Fig. 12, two electrodes are placed together, with or without an intervening diaphragm d. The electrolyte is circulated rapidly so as to prevent polarization. The pressure on the two sides of the diaphragm may be varied so as to facilitate the passage of liquid through the diaphragm. A current of low density is used. The particular combination of electrodes and diaphragms shown in Fig. 12 is for use in electrolysing an alkaline chloride to produce alkali and chlorine. When intended for preparing hydrogen and oxygen by electrolysing a caustic-soda solution, both anode and cathode are formed of wire netting ; but when electrolysing, for the same purpose, sulphuric acid, both are formed of carbon.

Title: An Improved Process of, and Apparatus for, Automatically Alternating Ground-patterns and Weft-borders Patterns in Figure Weaving, on Looms.
Inventor: BENDIX PAUL
Filed: 1901-03-09
Granted: 1901-08-24
Abstract: 5053. Bendix, P. March 9. Loom dobbies; jacquards; change-box motions.- Relates to means for automatically changing the pattern from the ground pattern to the weft border pattern, and vice versÔ, the change being determined by the length of the material woven. The invention is described as applied to a leaf loom, but it may be also applied to jacquard machines and figuredfabric looms with colour-changing mechanism. During the weaving operation, the hook t, secured to the shaft 12 of the card cylinder, rides on the bent extremity of a lever s, which is held in the position shown by a spring rod v, the needle frame d being supported by the flat or pointed portion of an elliptical cam e. When the pattern requires to be changed, a tappet 6 or 7 on the chain 3, which determines the length of the part woven, operates a pulley 4 connected by a cord to a spring rod o, which carries a projection p and is mounted on a spring lever i. The projection p is thus brought beneath a similar projection u on the spring rod v, which is forced upwards and turns the lever s so as to allow the hook t to fall and engage with the cam f on the shaft of the cam e. At the next reciprocation of the hook t, the cams f, e are turned through a quarter of a revolution, and the needle frame d is raised or lowered as desired, the cam f engaging in its revolution with a forked rod 10 and moving the lever i to the left, whereby the parts are brought into their original position and the hook t rides on the bent portion of the lever s as before.

Title: Improvements in Gas, Hot Air and like Engines
Filed: 1901-10-08
Granted: 1902-10-08
Abstract: 20,085. Lake, H. H., [Chicago Motocycle Co.]. Oct. 8. Gas and explosive-vapour engines ; hot-air engines. -The engine may work as an internal-combustion engine or a hot-air engine. It has a motor piston 3 connected to the crank 25 by a rod 26, and a displacer 12 also connected to the crank 25 by mechanism 28, 32, and 34. The chamber 2 is kept at a very high temperature, and the expansion of the charge therein forces the pistons outwards and turns the crank shaft in the direction of the arrow. At a certain point the displacer comes to rest, and the exhaust valve 48 is opened the piston 3 continuing its movement draws air through the port 41 and, if necessary, fuel through the port 42 into the cool part between the pistons. The charge on the in-stroke is forced past a valve 14 on the displacer into the hot chamber 2 and compressed. The chamber 2 is roughened on the outside, and is surrounded by a casing 7 and heated by a burner 60. When oil is employed for fuel it is heated, first in a passage in the seating of the exhaust valve, and then in a passage above the burner 60, to which some of the vapour may be supplied, and may then be conducted through a valve 61 and pipe 43 to the port 42. The vapour or gas is mixed with the air in passing from between the pistons to the chamber 2. For this purpose the part of the displacer which fits the cylinder has many longitudinal grooves 16, and the valve 14, which slides in a recess in this part, has radial grooves in its rear face ; it fits the cylinder tightly, and is constructed so as to allow the passage of gas from the front to the rear of the displacer only. Vaporizing oil in the exhaust-valve seating tends to cool the latter.
