Abstract: 11,299. Sch³ler, L., and Ferranti Ltd. May 18. Motors, controlling.-Relates to the starting and reversing of single-phase alternating-current motors of the repulsion type, or induction motors provided with a commutator &c. and adapted to start as repulsion motors. The magnetic axis of the stator is shifted to vary the direction of rotation. The stator is wound with a three-phase star-connected winding, two of the coils being used in series for starting, and a different pair of coils in series for reversing. Fig. 1 is a diagram showing the three coils A, B, C with terminals 1, 2, 3, and Fig. 2 shows the magnetic axes R, R' produced by connecting the terminals 1, 2 or 1, 3 to the singlephase mains. By connecting one pair, the rotor turns in one direction, and by connecting the other pair it is reversed. Fig. 5 shows a suitable winding, the stator having six slots a ... c<1>. J is the common point, and 1, 2, 3 are the terminals. The winding A may have a greater number of turns than the windings B, C, in order that the axes R, R' may be displaced less than 30‹ from the rotor axis x-x. According to the Provisional Specification, the rotor may have two independent sets of windings, although two windings may have a common terminal. The motor may have two sets of brushes, and the direction of rotation be determined by the pairs of brushes short-circuited.

Inventor: HEWISH EDGAR MILNE
Filed: 1903-07-18
Granted: 1904-01-21
Abstract: 15,941. Hewish, E. M. July 18. Pessaries; dressings.- Medicated tampons, pessaries, or pledgets for applying medicaments to the vagina &c., and for supporting the uterus, are made by compressing any suitable fibrous absorbent material in a mould, saturating with medicament, and afterwards dipping into a gelatinous compound, which forms an outer coating and keeps the article in shape. Or the inside of the mould may be coated with the gelatinous compound before introducing the fibrous material. The tampon may be shaped like a saucer, as shown in Fig. 4, or it may have a central opening. In use, the outer coating dissolves off, and, owing to the flexibility of the fibrous base, the fibres expand and maintain the article in position.

Title: Improvements in the Production of Process Blocks.
Inventor: DITTMANN THEODOR
Filed: 1903-07-25
Granted: 1903-12-17
Abstract: 16,447. Dittmann, T. July 25. Photo-mechanical printing. - Instead of using a screen in the camera to break up the negative, the breaking- up may be effected in copying from the negative, or from a transparent positive, on to the metal plate. One method consists in roughening the metal plate by etching it with acid before sensitizing it. The varying thickness of the film produces a network of slight graduated shades. A similar effect may be produced by pressing a filter screen on to the original negative, so as to produce depressions in its surface. A third method consists in acting on the metal plate with a special transparent screen as well as the negative. The screen may be combined with the negative. The screen is made by photographing or copying series of parallel, undulated, or zig-zag lines, the darkest parts being always transparent. When the screen consists of series of horizontal and vertical lines crossed by diagonal lines, the ratio of the length of each diagonal line to that of each horizontal or vertical line is 1 : #2. Fig. 4 shows such a network, in which each square, such as A, B, C, D, is broken up into sixteen portions all of different tone.

Title: Improved Process and Apparatus for the Electrolysis of Chlorides of the Alkalies.
Inventor: KELLNER CARL
Filed: 1903-09-29
Granted: 1903-12-03
Abstract: 20,889. Kellner, C. Sept. 29. Chlorine.-In the production by electrolysis of alkaline hydrates and almost chemically-pure chlorine, a hot unsaturated solution of the chloride of the alkali is compelled, either by differences of level or by exhausting the cathode compartments, to flow from the anodes to the cathodes through a filtering-diaphragm at a speed greater than that of the hydroxyl ions in the opposite direction. The electrolyte is of such a strength that it is almost exhausted when emerging from the cell. The diaphragm consists of asbestos, cellulose, or other inert material covered with a layer of loamy powder, such as barium sulphate. The conducting-area may be reduced if necessary by embedding powdered porcelain, glass beads, &c. in the diaphragm, or by covering it with perforated plates of slate &c. The anodes b, Fig. 1, may be arranged with their compartment a above the diaphragm d, which rests on wire netting c in a trough e constituting or containing the cathodes, supply and discharge pipes g, h being provided as shown. The cells may otherwise consist of frames, arranged similarly to those of a filter press and fitted with plates i, Fig. 3, acting both as anodes and cathodes. The frames are separated by diaphragms d so that each contains an anode and a cathode compartment a, e. The electrolyte is supplied through a pipe k, and the hydrate drawn off through pipes n fitted with hydrogen outlets o. The evolved chlorine deposits its moisture in bulbous tubes l on its passage to the outlet m, or bubbles through the electrolyte supplied through the tubes l. The electrodes i may consist of glass &c. plates wound round with wire, or of blocks of carbon projecting through holes in plates of slate cemented on both sides. Another form of electrode i consists of a carbon plate covered on the cathode face with a plate of iron, lead, or nickel, in contact with a platinum sheet which covers the anode face.

Filed: 1904-04-30
Granted: 1904-07-21
Abstract: 9944. Ducastel, F. J. M. M. April 30. Cements; mortars.-Pulverized substances, such as silica, silicates, and carbonates, are caused to react on lime or cement at suitable temperatures. The reacting substances are powdered in a crusher 2, and carried by a conveyer 3, to a washing-apparatus 4. They are then raised by an elevator 5 to the top of a drying-chamber 6, with sloping shelves 7 ; hot gases from the furnace 1, rising in the chamber meet and dry the descending material, which is then fed into the hopper 10 by the conveyer 8 and elevator 9, and thence into the ballmill 11, where it is further pulverized. A conveyer and elevator 13 feed the material into the hopper 14, where it is mixed with the cement or lime, also pulverized, which enters by the pipe 15. An endless screw transfers the mixed substances into the gas-heated rotary furnace 1 lined with flint masonry, and containing flint rollers, which further intermix and pulverize the substances, and facilitate their chemical reactions. The heated gas, consisting largely of carbonic acid, enters the furnace from the combustion chamber 18, and also reacts with the mixed material. The product, which is collected in chambers 16, and cooled out of contact with the air, forms a rapidly-setting cement; but if exposed to the air it forms a slow-setting Portland cement. Three examples are given of suitable mixtures for treatment. (1) Slaked lime, 16 to 22 per cent. ; grit or material containing silicate of lime, 78 to 84 per cent. (2) Quicklime, 10 to 18 per cent. ; crushed brick, 42 to 50 per cent. ; Portland cement, 40 per cent. (3) Residue from stone cutting, 50 per cent. ; crushed brick, 10 per cent. ; Portland cement, 40 per cent.
