mixture to each end of the cylinder, and a mechanically acting mixture-valve between the mixture-pump and each end of the cylinder, substantially as set forth. (9.) In the production of fuel for use in internal-combustion engines, subjecting crude or heavy mineral oil or petroleum to the action of a current of air, by which it is atomized in a chamber in which a partial vacuum is maintained, whereby the lighter portions of the oil are carried off by the air and the heavier portions separated. (10.) In the production of fuel for use in internal-combustion engines, subjecting crude or heavy mineral oil or petroleum to the action of a current of air, by which it is atomized in a chamber in which a partial vacuum is maintained, and causing the jet of air and oil to be projected on to a body, whereby the heavier portions fall on to the body and flow down it and the lighter portions are carried off by the air. (11.) Apparatus for producing petrol or petroleum spirit fuel for internal-combustion engines or heating purposes, comprising a chamber, adapted to be exhausted; an oil sprayer or sprayers connected with said chamber, having its or their deliveries within same, with oil- and air-supply conduits, and adapted to project the atomized fluid on to a suitable surface, or on to another jet, whereby the lighter oils are carried off by the air and the heavier or slimy portions flow down the surface of the apparatus and are separately withdrawn: substantially as set forth. (12.) In apparatus for producing combustible mixture of oil or spirit and air for internal-combustion engines, the combination of two or more oil or spirit sprayers or atomizers connected with a chamber, having their deliveries within said chamber, and disposed opposite each other, so that the streams of mixed air or oil and spirit strike each other, substantially as set forth. (13.) In apparatus for producing combustible mixture of oil or spirit and air for internal-combustion engines, the combination of two or more oil or spirit sprayers or atomizers connected with a chamber, having their deliveries within said chamber, and disposed opposite each other, so that the streams of mixed air or oil and spirit strike each other; and a surface heater connected with an exhausting and forcing pump, having a distribution-valve, by which a rarefaction or exhaustion of the chamber is effected and the mixture discharged. (14.) The apparatus for combustible mixture for internal-combustion engines having parts combined and adapted to operate as set forth with reference to the drawings.

No. 19380.—18th April, 1905.—OTTO FRÜHLING, of No. 5, Monumentsplatz, Brunswick, Germany, Civil Engineer. Improvements in suction dredging-apparatus.

Extract from Specification.—An apparatus with closed top and closed side walls, which I will call a bell, is placed over those points of the ground from which the soil is to be removed, the said bell, the front opening of which covers the soil to be removed, being inserted in a pipe conduit, one end of which leads into the open water, while the other end of the same is connected to the dredging-pump. The novel dredging-device is applied in two different modifications, according to the particular conditions prevailing in certain cases. A movable bell is used in cases where the dredging-device is to be constructed independently of the spaces to be emptied: thus, in the case of emptying ships which are to be placed close to the dredger, or in the case of deepening building-grounds or already existing waters.

No. 19381.—18th April, 1905.—OTTO FRÜHLING, of No. 5, Monumentsplatz, Brunswick, Germany, Civil Engineer. Adjustable dredger-head for suction dredgers.

Extract from Specification.—The essential feature of the said invention consists in the fact that the dredging-head is no longer rigidly connected with the suction conduit or with its support as heretofore, but that it is movably connected thereto. The movable connection, of course, may be effected in different ways, but the most serviceable connection will, of course, be that in which the head is capable of oscillation around an axis at the end of the suction conduit of its support.

No. 19388.—25th April, 1905.—CHARLES EDWARD EASTERBROOK SMITH, of Wakefield Street, Auckland, New Zealand, Contractor. Improved apparatus for cleaning and drying flax and the like.

Extract from Specification.—The apparatus comprises an endless belt running around rollers and between compression-rollers and a scraper and scraping-board, one of the compression-rollers being capable of lateral adjustment.

No. 19391.—26th April, 1905.—HARRY MERTON GAIL, of Buffalo, New York, United States of America, Mechanical Engineer. Improvements in telephone transmitters.

Claims.—(1.) A transmitter comprising a cylindrical body having its bore threaded, caps screwed into opposite ends of the body, partitions screwed into the body and dividing the same into a central chamber and two end chambers, a mouthpiece extending transversely through the body into the central chamber, a distributor arranged in the central chamber and having branch tubes extending from said mouthpiece through the central openings in the partitions, diaphragms arranged in the end chambers next to the partitions, a pair of electrodes arranged in each end chamber and having its members connected respectively with the adjacent diaphragm and cap, a fibrous sleeve surrounding each pair of electrodes and forming a cell between the same, and a granular body arranged in each cell. (2.) A transmitter comprising a tubular body the axis of which is arranged horizontally, caps arranged at opposite ends of the body, diaphragms arranged vertically in the body, a mouthpiece mounted on the body and having branches leading to said diaphragms, bolts extending axially through the caps and having their heads arranged within the casing while their nuts are arranged outside thereof, two pairs of electrodes, the inner members of which are connected with the diaphragms, while the outer members are secured to said bolt-heads, a retaining-sleeve surrounding each pair of electrodes and forming a cell between the same, a body of granular material arranged in each cell, a trunnion formed on each of said nuts, and a support consisting of a standard and two conducting-arms which are secured at their lower ends to said standard but insulated therefrom and provided at their upper ends with bearing-openings in which said trunnions are journalled. (3.) A transmitter comprising a body, a head, a diaphragm, a pair of electrodes secured respectively to said diaphragm and head, a retaining-sleeve surrounding both electrodes and forming a cell between them, a granular mass arranged in said cell, and a damping-device consisting of a ring interposed between said head and sleeve and having a plurality of spring arms and cushions applied to said arms and bearing against said diaphragm.
