Title: Improvements in Electric Motor Control Systems.
Filed: 1907-04-08
Granted: 1908-04-02
Abstract: 8153. British Thomson-Houston Co., [General Electric Co.]. April 8. Driving machines by electromotors.-Relates to a control system for two motors employed to drive a printing press at different speeds. Ooe motor C is connected through reducing gear and the other larger motor B is connected directly to the driving shaft A, and a source of variable voltage, such as a motor-generator F with means for varying the current in the field winding f, is employed. The change from the motor C to the motor B is effected, without altering the voltage of the generator, by connecting it in series with but in opposition to the armature of motor B across the supply mains E. The speed is then increased by diminishing the voltage of the generator and may, if desired, be still further increased by adding its voltage to that of the supply mains. The motor C is connected to the shaft A through a magnetic clutch D, and may be permanently connected to the generator F so as to run idle during the operation of motor B in-readiness to take up the load. A reversing switch J and controlling switch H are provided.

Title: Improvements in Air Brakes.
Inventor: WRIGHT JOHN BUNYAN
Filed: 1907-04-15
Granted: 1907-07-11
Abstract: 8767. Wright, J. B. April 15. Brakes.-Air brakes are applied by the derailment, or an abnormal movement, of the car axle-truck. A branch 15 on the train-pipe B is normally closed by a spring-pressed valve 17, the stem 18 of which is pivoted to a lever 25. This lever extends into a slot 23 in a rod 22, which can slide in an extension 21 of the valve casing, which is secured to the car frame. When the rod 22 is moved vertically, the lever 25 is rocked about one of its rollers 26, whereby the valve 17 is uns e a t e d and the train-pipe vented through the port 20. Arms 10 carried by the truck bolster A support a bar 11 which extends through a link 34, pivoted to the rod 22 and normally retained horizontal by springs 35. Should the truck leave the rails, the bar 11 engages the link, moves the rod 22, and so applies the brakes. If there is abnormal turning movement, one of the cams 12 on the bar 11 engages the link 34 and applies the brakes. A spring stop 33 engages a notch 32 in the valve stem when the valve is unseated and holds it open. In a modification, Fig. 4, a ball 41 carried by the valve stem 18 normally fits in a socket 40 in the rod 22, so that, when this rod is moved vertically, the stem 18 is pressed back and the valve opened.

Granted: 1908-05-21
Abstract: 12,238. British Thomson - - Hous - ton Co., (Allgemeine Electricitõts Ges.]. May 27. Switches, electrically tripped. Relates to manually-operated switches provided with electro-magnetic detents for controlling the power circuits of electricallyoperated signals, points, and the like, in which two circuits are employed to change the direction of rotation of the motor. When a hand-lever 7, Fig. 1, is operated, the switches 8, 9, 10 are reversed, and the armature of the magnet 11 retains the switches 9, 10 in the position shown in dotted lines, so that the current flows from the battery +12 through the switches 9, 8, lead 2, field coil 13, and armature 14 to earth and battery -12. On the completion of the movement of the signal or point, the magnet 11 is energized, and the switches 9, 10 are released and returned to their normal position. The motor circuit is thus broken at the switch 9, and the leads 1, 2 are again short-circuited through the switch 10. The reversal of the signal or points is effected by moving the switch 8 back to the position shown in full lines, the switches 9, 10 being simultaneously moved into the positions shown in dotted lines to close the circuit through the coil 15 of the motor. Modified forms are also described.

Title: Improvements in or relating to the Treatment of Bamboo Pulp and other similar Materials.
Inventor: TURNER JAMES SCOTT
Filed: 1908-03-20
Granted: 1909-06-21
Abstract: 6277. Turner, J. S., and Maxwell, A. W. March 20. Drawings to Specification. Bleaching.-Bamboo pulp and the like is prepared for bleaching by steeping it in sea-water or other suitable salt solution containing oxygen in solution, sulphuric or other acid being added, then washing, and finally steeping in a weak alkaline solution. The salt solution may be prepared by electrolyzing brine in a special apparatus. The same solution, diluted, may be used for the subsequent bleaching proper. The sulphuric acid may be prepared by electrolyzing sulphurous acid in a similar electrolyzing-apparatus. Brine, preferably made by adding salt to sea-water, is electrolyzed in the special apparatus, wherein a current is passed just sufficient to decompose part of the water in the flowing brine without liberating any chlorine or metals. The portion carrying free oxygen, which is absorbed by the brine, passes to a cistern ; similarly the other portion, already partly freed of hydrogen, falls on to a stepped cone, which further frees it from gases, and passes away to a cistern through conduits. The solution containing oxygen is preferably used alone but may be diluted with the other portion freed from hydrogen. The oxygenated brine is run with dilute sulphuric or other acid into a mixing-vat, and in the resultant yellow solution the bamboo or other pulp is steeped until the whole mass becomes a bright lemon-colour ; the solution is then drained off and the pulp washed. The pulp is next steeped in a suitable weak alkaline bath, for example of lime-water, caustic soda, or mixed sodium carbonate and borax, until the mass is dark brown. On again washing, a well-cleaned cellulose free from encrusting matter, remains. The pulp may then be bleached, as with the above yellow solution, much diluted, or with a 2 per cent solution of bleaching-powder.

Granted: 1910-08-29
Abstract: 19,768. Greenwood, C. V., Stocks, H. B., and White, H. G. Aug. 28. Gums, carbohydrate and like.-Gum tragasol is obtained from the endosperms of the locust bean, or other suitable raw material, which have been prepared by alternately exposing the kernels to the action of saturated steam and warm water. This process loosens the husk and cotyledons from the endosperms, and they are separated by passing the treated kernels through one or more ordinary brush decorticating machines, whereupon the endosperms are dried and either stored or at once extracted. The extraction is effected by steeping and afterwards digesting in steam-heated open pans at about 200‹ F., or, if tragasol containing more soluble matter is required, in closed pans at from 230-300‹ F. A combination of both methods may be used. After filtering and cooling the product, a little preservative may be added to facilitate keeping. For various industries, the product may be mixed with other materials such as waxes, resins, gums, oils, pectinous substances, starchy materials, or any colloid body having a reversible solvent action, or any suitable hard, elastic, soluble, compound. Specifications 27,186/03, 10,822/05, and 569/08 are referred to. According to the Provisional Specification, the loosening process may be hastened and assisted by the addition of such substances as formalin or alum to the steep water. Also the product may be marketed drier than in the solution or jelly form.
