Inventor: JUNKERS HUGO
Filed: 1902-06-09
Granted: 1903-04-23
Abstract: 13,113. Junkers, H. June 9. Water and other liquid heating stoves.-To transfer heat to the liquids, metal plates are placed in the paths of the heating gases, the plates abutting at their ends upon the walls in contact with the liquids. The plates may be flat, bent, involute, or U-shaped, and may be of uniform thickness, or may vary in thickness either in the direction of motion of the gases, or at right-angles thereto, the result being that the cross-section of the flues is divided into narrow passages. Among the forms the plates may take and their positions, Figs. 2, 6, 15, and 18 serve as illustrations. In Fig. 2, the flue area between the liquid spaces b, shown in sectional plan, is filled with radial or curved plates I, II. In Fig. 15, U-shaped plates y forming flue spaces x between them are employed. In Fig. 18, the plates are shown as varying in thickness.

Title: Improvements in Electric Motors.
Inventor: LAMME BENJAMIN GARVER
Filed: 1902-12-04
Granted: 1903-07-16
Abstract: 26,746. Lamme, B. G. Dec. 26, A.D. 1901, [date applied for uuder Patents Act, A.D. 1901]. Motors, alternating-current.-A single-phase alternating-current series-wound motor is so designed that the ratio of the field-magnet self-induction to the armature counter-electromotive-force is approximately equal to the ratio of the line alternations to the armature alternations (product of field poles and revolutions), and this ratio is made low by providing the motor with a comparatively large number of field poles- The ratio of the number of field poles to the number of current alternations per minute may conveniently be 1 : 250 ; for example, a motor working at 2000 alternations per minute may be provided with 8 poles. The ratio of field ampÞre-turns to armature ampere-turns must be between the limits 0À5 and 0À75, and in a particular instance is 20 : 27. Certain features are introduced in the construction of the motor for the purpose of limiting the field-magnet self-induction and the armature cross-flux, and for preventing sparking at the commutator. Fig. 1 shows a part section and part elevation of an 8-pole motor embodying the invention. The armature is provided with a closedcoil parallel winding 8, and the end connectors 9 are joined to the several commutator bars 14 by means of relatively-high resistance leads 15, such as, for example, strips of german silver, so as to reduce the secondary currents in the short-circuited sections of the armature winding and thus prevent injurious sparking. A certain number of the end connectors are also joined to balancing- rings 13. To limit the field self-induction and the armature cross-flux, the polar projections 19, Fig. 7, are provided with slots 20, transverse to the direction of rotation, and the depth of the body portion of the core is reduced at the rear of each polar projection. In some cases, a copper conductor 22, Fig. 8, is inserted in one of the slots, and a plate of copper may also bo introduced at 23. The field winding 25 comprises eight coils of strap copper, bent edgeways and connected in series. The parts are mounted in a casing 26, which projects inwards at the backs of the poles to form supports for the cure. The casing may also be of open-work or skeleton construction. Motors, controlling. - Motors of the kind described above are preferably controlled by varying the electromotive force applied at their terminals. For this purpose, a transformer is interposed between the motor and the supply mains, the electromotive force of the secondary being varied by varying the number of windings of the primary or secondary, or by varying their magnetic relationship. A convenient means consists in the employment of a three-coil transformer, the third coil of which is connected with the primary coil of a second transformer, the secondary coil of which is in series with the secondary coil of the main transformer.

Patent GB-190316497-A (GB)
Title: Improvements in and connected with the Manufacture of Gas.
Inventor: WOODALL HAROLD WHITEMAN
Filed: 1903-07-27
Granted: 1904-06-09
Abstract: 16,497. Woodall, H. W., and Duckham, A. M. July 27. Gas-producers.-Relates to the continuous production in the same retort of coal gas and water gas. The retort a is set in a substantially vertical position, so that the charge may descend by gravity, and is surrounded by flues c. The retort is preferably slightly conical, being larger towards the bottom, and is oval in cross-section. The feeding device, which may be arranged to feed two retorts simultaneously, consists of a drum g<1> revolving in a cylindrical casing g. As the opening g<2> passes the shoot g<3>, the drum is charged with coal, which it discharges as the opening passes the shoot f; or, instead of a drum, a reciprocating slide may be employed. The producer or other gas for heating the retort is introduced into the top flue w from the passage t at ports n, where it meets an air supply which enters through ports o the products of combustion passing down through flues c to the shaft p. The retort is thus heated most strongly at the top. The air supply is heated by being drawn through passages between the top of the brickwork b and an iron casing r packed with non-conducting material s. The coke descends into a sump containing water, and is removed by a conveyer. The bottom of the retort may be partly closed by a plate k. The steam caused by the quenching of the coke passes up into the retort, the steam being decomposed and water gas formed. Additional steam or steam and air may be injected into the bottom of the retort. The water gas may be drawn off with the coal gas, or separately through exits at an intermediate part of the retort.

Granted: 1905-08-03
Abstract: 21,208. Brasseur, C. L. A. Oct. 3. Drawings to Specification. Chromo-gelatine processes; printing.-Gelatine films for a photographic transfer printing process are supported on paper from which they are separated by a layer of easily-soluble material such as gum, albumen, wax, varnish, &c. The gelatine film is coloured and unsensitized, or an insoluble coloured gelatine which is rendered soluble by action of light may be used. Either form may be coated on to the prepared paper direct, but, if thin even films are required, the gelatine is first coated on to prepared plate-glass and the paper squeezed on to it. This method allows of examination of the film for equality of colour and determination of wave-lengths of transmitted light. To use the prepared paper, the gelatine is squeezed on to the printing-surface to be used, the paper support is removed, and the film sensitized, printed, and developed. This film may then be rendered impermeable, and a second one may then be superposed and printed. Any desired number of films may be added, one by one.
