Title: Improvements in and relating to Rotary Members for Dynamo Electric Machines.
Filed: 1906-05-22
Granted: 1907-04-25
Abstract: 11,936. British Thomson-Houston Co., [General Electric Co.]. May 22. Armatures ; field magnets; cooling and ventilating. -The rotary member of a dynamo-electric machine is provided between each pair of poles with an adadjustably expansible split brace, for holding the windings against the pole-pieces to prevent distortion. In the construction of rotating field magnet shown in Fig. 1, each brace comprises two members 17, of the form shown in Fig. 3, and a middle wedge-shaped piece 18, which engages between them and has a screw part 20 with a nut 21 by screwing down which the brace can be expanded. The wedge may have a stop to prevent complete withdrawal. Two such braces are placed between each pair of poles, each brace being held by a pair of end straps 24, the ends of which are secured in gaps in the core structure. Bolts 26 pass through the end straps and through elongated slots 28 in the brace, and are tightened up when the brace has been adjusted so as to prevent radial displacement. By loosening these bolts, the brace may be re-adjusted to compensate for shrinkage of the insulation. The core structure is built up of bundles of laminµ, each comprising two pole portions 8, 9 of unequal length and a connecting portion 10. In each pole-piece the parts 8, 9 occur alternately, the pole-tips being completed by pieces 14 secured over the ends of the portions 8 and between the ends of the portions 9 by rivets, keys, or rods 15. In the parts of the core between the pole-pieces, the bundles of laminµ alternate with air-gaps of equal width. The keys 15 are extended at each end to secure pieces 30 over the ends of the windings, and the ends of the keys pass through side plates 31 which form two annular shields for forcing the outflowing air to pass through the surrounding armature. Specifications No. 12,080, A.D. 1902, and No. 7384, A.D. 1903, are referred No. 384, A.D. 1903,

Granted: 1906-08-30
Abstract: 14,352. Boeken, H. J. July 29, 1905, [date applied for under Patents Act, 1901]. Scutching-apparatus.-Fibrous plants are lowered to and raised from a scutching - apparatus in a vertical direction so that they are progressively scutched. The material is placed on conveying- ropes 28 and carried forward in a well-known manner to a transporting-belt 1 and ropes 3, where it is bent into the shape shown in Fig. 4 by means of a grooved pulley 21. On reaching the scutching- cylinder 30, fitted with knives 32, the material is supported by adjustable contact-rollors 37, which offer but one line of contact during the progressive scutching. The fibre, in ascending to the pulley 7, is divested of. any remaining fleshy substance and transferred, by means of the cone pulley 47, to a second set of ropes 4 and transporting-belt 2, the fleshy part of the fibrous material, which was held in the first set of ropes, and pulleys being brought into position for scutching by the cylinder 31 and contact-piece 37. The fibre is finally withdrawn by the ropes 29. The scutching-cylinders are driven in opposite directions from a countershaft.

Title: Improvements in or relating to the Manufacture of High Percent Manganese Steel.
Inventor: KELSALL CHARLES HENRY
Filed: 1906-09-14
Granted: 1907-09-05
Abstract: 20,452. Kelsall, C. H. Sept. 14. Manganese steel.-In the manufacture of high per cent manganese steel, molten steel, low in carbon and silicon, is overcharged with oxides by adding about 1 cwt. of iron ore to each ton of steel. Before tapping the steel from the furnace, À5 per cent of ferro-manganese is added to raise the temperature and clear the slag. The carbon in the ferro-manganese is insufficient to reduce all the oxides in the steel, which is run into a heated ladle, the desired quantity being afterwards run into another ladle containing molten rich ferromanganese. The remaining steel, if any, in the first ladle is used as ordinary steel. Or the steel may be run directly from the furnace into a ladle containing the ferro - manganese. The resulting steel is stated to be suitable for the manufacture of armour plates, gun forgings, projectiles, tramway rails, points, and crossings, dredger work, and other purposes. Also it is non-magnetic or feebly magnetic, and may be used for electrical purposes,

Abstract: 8979. Keene, A. April 24. Printing-apparatus combined with apparatus for registering fares.-Taxameters of the kind described in Specification No. 17,463, A.D. 1905, [Abridgment Class Registering &c.], are provided with an attachment carrying printing - wheels f, g actuated through chains h in conformity with the drums indicating the fares and extras. The printing-mechanism is described in Specification No. 10,108, A.D. 1895, [Abridgment Class Weighing- apparatus], and is adapted to print the fare on a ticket i inserted in a tray i<1> and on a strip j retained within the apparatus. The printing-rollers are provided with raised type, and the back of the record strip may be coated with carbon &c. to give an inked impression. A crank on the flag is connected by a link to a rod o actuating a bell-crank p by means of a pin and slot. The bell-crank communicates its backward motion through a spring catch q<1> to a T-headed slide q adapted to move in the eye r<1> of a standard r. Impression rollers, adapted to press the ticket and strip on to the printing- disks, are loosely mounted on a shaft k<1> which is carried by the slide q and moves in guide channels formed in plates s carried upon parallel guides s<1> forced upwards by springs. A spring k<2> is provided to force the rollers into the lower part of the track. When the right-hand extremity of the travel is reached, the spring catch q<1> is withdrawn from the bell-crank, and the rollers are returned by a spring. During the return movement, the ticket is ejected by a spring i<4>, which presses upon the ticket at all points of the path of the roller except when in engagement with a bevelled stop i<5>. The record strip is carried by two spools t connected by a spring and mounted on the detachable base u of the casing. The strip is fed forwards by pins, capable of yielding in one direction, which engage in holes therein and are carried on a plate x moving in guides against a spring x<1>. The plate x bears a spring part y which is engaged by the bell-crank in its forward movement. The distance run may be stamped on the ticket and strip, and the mechanism may be housed in the taxameter casing. Specification No. 8391, A.D. 1908, [Abridgment Class Registering &c.], is referred to.
