Title: Improvements in Alternating Current Generators.
Inventor: GIOVANNI BATTISTA MARZI
Filed: 1905-06-14
Abstract: 12,386. Marzi, G. B. June 15, 1904, [date applied for under Patents Act, 1901]. Void. [Published under Patents Act, 1901.] Armatures; field magnets.-Relates to alternating-current electric generators in which the armature rotates between the opposite pole-pieces N, S, Fig. I, of the field 3 ; the armature is provided on each side with twice as many teeth 2 as the field, the teeth of which are arranged so that those of one polarity come opposite the intervals between those of the opposite polarity. The teeth 2 are of half the thickness of those of the field. With this arrangement, the direct magnetic flux between the N and S pole-pieces of the field does not vary in strength, although the flux in each armature tooth is continually varying between zero and a maximum. In order that the length of the path of the field flux through the armature may be constant, the armature is provided with holes 4, Figs. I and II. The path of the armature counter flux is partly completed through the teeth on the field and partly through the teeth of two rings 5 and 6, Figs. IV and VI, arranged respectively outside and inside the armature ring 1. The field may rotate within the armature, in which case the teeth both on the armature and the field are arranged radially instead of axially. In the case of small machines used for telegraphic and other purposes, the field electro-magnets may be replaced by permanent magnets.

Patent GB-190605775-A (GB)
Title: Improvements in the Production of Ferrocyanides from Cyanogen Contained in Gases.
Inventor: JOHNSON JAMES YATE
Filed: 1906-03-09
Granted: 1907-01-10
Abstract: 5775. Johnson, J. Y., [Feld, W.]. March 9. Purifying gas.-In the production of ferrocyanides by the purification of coal-gas or the like by means of an iron compound together with a basic substance, conversion of the iron into sulphide is prevented by treating the iron compound with a ferrocyanide of an alkali, earth alkali, ammonium, or magnesium, before the iron compound comes in contact with the gas to be purified. Ferrous sulphate may be treated with calcium ferrocyanide, forming calcium sulphate and ferrous ferrocyanide. The ferrocyanide used may be soluble or insoluble. Thus calcium potassium ferrocyanide may be used instead of calcium ferrocyanide. In an example, ferrous-chloride solution is treated with enough calcium ferrocyanide to precipitate all the iron, but an excess of calcium ferrocyanide is not injurious. At least two molecular proportions of lime for each molecular proportion of iron is then added, or may be added to the iron compound or to the ferrocyanide before these substances are mixed. The absorption of the hydrocyanic acid is quicker and more complete than it would be if no ferroeyanide were added, and the product of the reaction is calcium ferrocyanide. For washing the gas, the liquor or the gas may be either hot or cold, and the gas may or may not contain ammonia. If ammonia is present, some insoluble ammonium calcium ferrocyanide is formed, but this formation is less at higher temperatures. Instead of ferrocyanide, liquor in which gas has been washed and which contains ferrocyanide may be used. If too dilute, the ferrous ferrocyanide produced should be filtered and mixed with water or milk of lime in the required proportion.

Title: Improvements relating to Steam Heating Systems
Inventor: WESTWOOD JOSEPH WILLIAM
Filed: 1906-06-12
Granted: 1907-05-09
Abstract: 13,438. Westwood, J. W. June 12. Heating buildings; heating water.-Relates to the steam-heating of buildings, and comprises the circulation through the supply mains of a system of high-pressure steam which is intermittently admitted to and discharged from the radiators or other elements by way of automatically-controlled valves situated respectively at the inlet and outlet ends of the said elements and adapted for simultaneous and conjoint operation. The radiators b receive high-pressure steam through mains c, c<1>, and discharge the steam by way of the mains d, d<1>. The combined mechanical admission and discharge valves with which each radiator is provided are shown at b<1>, b<2>, respectively. The result is that, on the discharge of the spent steam and condensation water from the radiator, the admission valve is opened to pass a fresh supply of live steam and that neither the admission nor the exhaust valve is constantly opened. The exhaust steam is collected in the condenser e, which when water-cooled may form part of a hot-water system, so that the heated condensing-water is conducted to a tank f for domestic purposes. From the condenser, the water flows to the receiver h and is passed to the boiler by automatic devices such as a float operating a valve to admit steam to a pump or ejector or to the receiver itself. The radiators below the boiler drain into the receiver h<1>, from which it is raised to the condenser e by steam from one of the pipes c<1>.

Title: Improvements in and relating to Pneumatic Despatch Tube Apparatus.
Inventor: FORDYCE EDMOND ARMITAGE
Filed: 1906-09-17
Granted: 1907-03-14
Abstract: 20,625. Fordyce, E. A. Sept. 17. Pneumatic d i spatch apparatus.- Where suction i s maintained through an outgoing transit-tube A and a return transit-tube K<3>, an atmospheric valve D is opened automatically o n the insertion of the carrier, and is closed automatically under the control of a timing- device. The insertion of a carrier into the outgoing tube opens a valve C at the end of a pipe L which admits atmospheric pressure to the bottom of a cylinder J, the top of which is connected by a pipe K to the suction pipe K<1>. The piston H being accordingly raised, the main atmospheric valve D is opened, and the carrier leaves the subsidiary valve C closed again. Suction through a throttle valve at the bottom of the cylinder then gradually reduces the pressure to let the piston sink and reclose the main valve. Insertion of a carrier into the return tube K<3> at the lid A<4> temporarily restores atmospheric pressure in the outgoing tube A, so that a diaphragm in a pocket L<3> is pressed outwards and opens a valve L<8> at the end of a pipe L<1> which communicates with the bottom of the cylinder. Atmospheric pressure then raises the piston as before.
