During the first portion of both upward and downward movements of the lever D, the carrier and nut are connected by the sliding piece F and the spring- controlled latches 11, 17, so that they move together, the lug e<1> on the nut engaging in a slot in the connector F, while the lug c<2> on the carrier engages the upper surface 12 of the latch 11 in its downward movement, and the undersurface 20 of the latch 17 in its upward movement. When the nut e has reached the lower limit of its movement, the latch 11 is disengaged by a cam, the nut then remaining stationary while the corkscrew passes through it into the cork, the lug c<2> also passing and engaging under the latch 17. On the downward movement of the lever D, the corkscrew, carrier, and nut move upwards until the cork is withdrawn. The latch 17 is then disengaged by the cam 21, and the nut remains stationary while the cork is stripped from the screw by the further upward movement of the latter. At the end of the operation, an arm 27 on the lever D or other operative part pushes the drawn cork out through an aperture 28 in the back of the casing, so that it falls into a suitable receptacle G pivoted to the frame. The neck of the bottle &c. is held between two pivoted gripping-jaws 32, 33, operated by another band-lever. At the commencement of the operation, the pivots of the lever D move outwards in the slots 8, and in consequence of this movement the arm 27 is drawn clear of the path of the nut E, so that it does not obstruct the movement of the nut.

Granted: 1903-04-25
Abstract: 9707. Lundeberg, A. F. April 26. Coated fabrics.-Relates to a method of and means for printing or colouring and making linoleum or floor coverings, wall papers and other fabrics, in which the colouring-matter in the form of powder is drawn on to or into the material by air suction. In printing linoleum, the ground composition of cork &c. with linseed oil &c. is applied loosely to the fabric backing, and, while it is in this condition, the colouring-powder is applied, and the linoleum is afterwards finished by rolling, drying, &c. as usual. Fig. 1 shows an elevation and Fig. 2 a plan of an apparatus, in which the fabric, covered with the layer of composition 12, is passed under the printing block or device 1, 2, and over a suction box 8 connected by a pipe 9 to an air-suction device. The box 8 may have a grating for supporting the fabric, and wire netting 11 may be passed under the fabric. The printing-block consists of a board or plate 1 having fixed in it thin plates or walls 2 forming cells of the required pattern, and the edges of these are pressed on to the fabric during the printing operation. Each cell is connected by a tube or tubes 6 to one or more colour receptacles 3 in which the powdered colour is agitated by revolving stirrers 5. The tubes 6 are connected to tubular nozzles 7 which may vary in length to modify the shading or colour effect. The shading or colour effect may also be varied by connecting the receptacles of different shades or colours to one cell of the printing-block. Fabrics for thin floor or wall coverings, not having a coating such as 12, may be coloured in a similar manner by applying colour to the surface or into the body of the fabric. They are afterwards finished by rolling &c. When applied to the surface, the colour powder may be mixed with a composition such as that of linoleum &c. The colour powder is preferably prepared with a small quantity of resin or oxidized oil, so that, when applied to the layer 12, it will not injuriously affect its cohesive properties.

Abstract: 23,642. Trantom, W. Oct. 29. Potassium chloride; salt, common; salts; sodium nitrate.-Relates particularly to methods of purifying brine, especially for use in electrolysis or for table use, but is also applicable for purifying solutions of potassium chloride, sodium nitrate, and other salts. (1) When the brine contains calcium and magnesium sulphate as impurities, a slight excess of barium carbonate is added, and the whole agitated in the cold, when a mixed precipitate of barium sulphate and calcium and magnesium carbonate is obtained ; or lime may be first added to precipitate the magnesium as hydrate, after which the barium carbonate is added. In either case, on filtering or otherwise separating, a pure brine is obtained. (2) When the brine also contains calcium or magnesium chloride, or both, sodium sulphate is first added, after which the barium carbonate is added as above. In the case of a potassium-chloride solution, potassium sulphate is added. The precipitate, obtained as above, is treated with an acid, especially sulphurous acid, to separate out the calcium and magnesium, leaving the barium sulphate, which is regenerated for re-use as follows :-It is first reduced by coal to sulphide, and the latter converted into carbonate by adding, for example, an alkaline carbonate. The barium carbonate is used in the purifying process while freshly precipitated, and without previous drying, its action being in this condition from 30 to 50 times as rapid as that of the dry salt.
