Title: Improvements in Transforming Alternating into Continuous Electric Currents or vice versa.
Inventor: MUELLER ADOLPH
Filed: 1897-05-25
Granted: 1898-04-09
Abstract: 12,957. M³ller, A., and Tudor, H. May 25. Converting alternating and direct currents.-Relates to means for converting alternating into direct currents, and vice versÔ, for charging secondary batteries &c. In converting an alternating current from a generator A, a commutator B is driven synchronously by a motor C, and to prevent sparking at the contacts a polarization battery H is switched in for the period when the tension of the current is below that of the secondary battery. The commutator carries a number of contacts b<1>, b<2>, b<3>, b<4>, b<5>, connected as shown with rings d', d<2> on which rub the brushes D<1>, D<2> connected with the battery G. Between these contacts are contacts b<12>, b<23>, b<34>, b<45>, connected to the rings f<1>, f<2> on which rub brushes F', F<2> connected with the polarization battery H. The brushes E<1>, E' are connected to the generator. The apparatus may be used for converting continuous into alternating currents by supplying a continuous current from a battery G or other source, and rotating the commutator by a suitable motor. Similarly, it is stated, polyphase currents may be converted, and vice versÔ.

Title: Improvements in the Manufacture of Linoleum.
Inventor: BEDFORD JAMES EDWARD
Filed: 1899-04-07
Granted: 1900-02-24
Abstract: 7315. Bedford, J. E., and Bedford, C. S. April 7. Coated fabrics.-Relates to improvements in the process described in Specification No. 11,716, A.D. 1895, for printing linoleum in such a way that the design penetrates into the body of the material. The canvas backing is first coated with glue or varnish, and then the linoleum meal, which may be white or nearly so, or may consist of mixed materials giving a granite effect, is applied to it. If the thickness of the linoleum when finished is to be 2 to 2¢ mm., about 12 mm. of the loose linoleum meal is applied. After the spreading operation, the linoleum is compressed by rolls to 4 or 5 mm , and is then printed, preferably by a horizontal block machine, in which each block can be applied twice to a given portion of the fabric. The fabric is next passed on to a hydraul press, its upper surface being protected by a speciallyprepared paper. The paper for this purpose is treated with wax or dextrin, and before use receives on its under side a coating of size, varnish, oxidized oil, or linoleum cement ground up with benzene or turpentine. After the pressing operation. the paper may be removed, or it may remain on till the linoleum is finished. The fabric is next passed over rollers in a stoving room to evaporate the volatile materials used with the pigments, and is finally consolidated by pressure between heated rollers or plates.

Patent GB-190104669-A (GB)
Title: Improvements in and relating to Reversing Rolling Mills.
Inventor: HODGSON JOHN GEORGE
Filed: 1901-03-05
Granted: 1901-09-07
Abstract: 4669. Hodgson, J. G. March 5. Rolling.-A reversing-mill for rolling bars, plates, sheets, or packs of sheets is provided with hydraulic mechanism for automatically adjusting the pass after each reversal. The adjusting- screws 21, 22 can be adjusted by handoperated worm gearing 23 or by a rack 26 operated by a ram 27 in a cylinder 28. Friction clutches for reversing the mill are operated by a ram controlled by a reversing-valve 17 connected by pipes 18, 19 with the cylinder. The reversing- valve handle 20 may be connected by a link 42 with a valve-lever 41 controlling the admission of lowpressure fluid to a cylinder 39, the piston of which carries a cam bar 36. When the handle and lever are uncoupled, the mill can be reversed independently of the feed, but, when coupled as shown, the movement of the handle 20 admits fluid to the cylinder 39, causing the cam bar to open momentarily a valve 29, having a weighted lever 33 with a roller resting on the cam bar. The valve 29 permits a small amount of fluid to escape from the left end of the cylinder 28 through a pipe 30. Pressure-fluid, supplied by a pipe 50 with a twoway valve 49, causes the .ram 27 to advance and open a valve 31 by means of a notched bar 46 and weighted lever with a roller 44, the roller passing out of a notch in which it has been resting. The valve 31 allows the exhaust from the left end of the cylinder 28 to continue through a pipe 32, the ram advancing and operating the feed-screws till the roller 44 drops into the next notch and closes the valve 31, stopping the advance of the ram. The bar 46 attached to the ram 27 is suitably notched, so that the downward feed of the rolls becomes less and less after each pass, and is interchangeable with similar bars for different classes of work. To return the ram and screws, the handle 53 of the valve 49 is thrown over, allowing the right end of the cylinder to exhaust through the pipe 50, and opening a valve 51 by a link 55 and handle 54 to admit pressure fluid to the left end through a pipe 52. The rolls may be set down several notches at once by holding up the lever 33 of the valve 29.

Title: Improvements in Internal Combustion Motors
Inventor: ROBB WILLIAM JOHN
Filed: 1901-03-20
Granted: 1902-06-05
Abstract: 5857. Robb, W. J. March 20. Gas and like engines.-The volume of the combustion chamber is adjusted either by moving the cylinder relatively to the crank shaft or by varying the stroke of the piston. The former method is carried out as shown in Fig. 1, a dovetailed foot on the cylinder being slid in V-grooves in the bed-plate by a screw F. The cams E, E' are elongated so as to engage the valve stems in all positions, and shaped so as to admit a charge proportional to the combustion chamber capacity. The crank and countershaft bearings may be the movable members. The application of the latter method is shown in Fig. 5. The piston-rods J engage blocks on a rocking lever H. The blocks are adjusted radially by screws L operated through bevel gearing and a shaft co-axial with the lever H. The motion is transmitted through an arm H<4> to the crank shaft. The admission-valve cam may be adjusted simultaneously with the piston stroke.

Granted: 1902-05-15
Abstract: 10,724. While, J. M., and Rushton, J. May 23. Bending.-A machine for coiling hoop-iron and the like as it issues from rolling-mills has a table 8 supported by a central pivot 10 and rollers 9, above which is a plate 4 carried by a vertical shaft 2 and through which project split taper studs 6 on a spider 7 feathered on the shaft 2. The spider normally rests in its lower position, the studs forming a reel on which the hoop-iron is wound, the distance between the table and the plate 4 being adjusted to suit the width of the hoop-iron. The leading end of the hoop-iron is readily secured to one of the studs by inserting it in the slit, and, after the coil is completed, it is stripped from the studs by raising the spider by means of a handle 7<f> on a rock-shaft 7<e> with an arm 7<d> engaging the spider. To facilitate removal of the coil, the plate 4 may be capable of vertical move ment, which may be imparted to it and the shaft 2 after the coil has been stripped by the further upward movement of the spider, a collar 4<a> on the shaft being engaged by the spider. The plate 4 is locked until the coil has been stripped by arms 4<e>, 4<g> on a rock-shaft 4<d>, the arm 4<q> passing under a pin 4<b> on the handle and the arm 4<c> resting on the collar 4<a>. The shaft 2 is driven by bevel gearing 3. The spider 7 may have only two studs, so that a flattened coil is produced, or it may have sufficient studs to form a circular or elliptical coil which is afterwards flattened. Fig. 3 shows a suitable form of flattening-apparatus. The coil is placed between a fixed abutment 11 and a sliding bar 12, guided by a bar 14 and operated by pairs of toggle-levers 17 connected by links 20 to counterweighted handles 23 carried by a shaft 22.
