Abstract: 7141. Carolan, E. A., [General Electric Co.]. March 27. Field magnets; motors, controlling. -Relates to arrangements for altering the speed of two-phase alternating-current motors by varying the number of effective poles by changing the connections. The Figure shows the field wind ing of a two-phase motor, in which the number of effective poles can be varied in the ratio of two to one, by throwing over the switches L, M. The leads G, H supply the current of one phase, and the leads K, I the second. The contact 25 of the switch L is connected to the terminal conductor B, and the current divides, when the switches are in the position shown, at the connection with the winding. Similarly, the contact 27 of the switch M is connected to a terminal conductor E leading to a point in the winding, so that the current of the second phase also divides. The switches are in the position for full speed, the motor having momentary poles S<1>, S<2> and N', N<2>, as shown in the upper part of the squares indicating the polepieces. The index numerals indicate the phase producing the poles. On throwing over the switches L, M, the contacts 25, 27 are opened, and the currents now flow to produce the poles as marked in the lower parts of the squares.

Title: Apparatus for Treating Pulp Stock.
Inventor: JUSTICE PHILIP MIDDLETON
Filed: 1903-04-21
Granted: 1903-07-16
Abstract: 8984. Justice, P. M., [United States Fibre Stopper Co.]. April 21. Paper machines.-Relates to apparatus whereby pulp stock in a relatively fluid condition is subjected to drying and condensing actions, to bring it to the proper consistence to be worked in a forming-machine or the like. The framework 9 of the apparatus may be made of gas piping, as shown, or may be of other suitable construction. The fluid pulp is fed from the hopper &c. A through the shoot 42 on to the surface of the perforated rotating cylinder B, on which it is formed into a thin web or bat. A portion of the water escapes from the pulp through the cylinder, and is caught in a drip-cup suspended from the shaft 33 of the cylinder, the drip-cup having a suitable discharge pipe 41". The cylinder is fixed at one end to a spoked rim mounted on the shaft 33, and is open at the opposite end, through which the pipe 41<a> projects, the latter end being strengthened by an edge ring. The web or bat formed on the cylinder B is delivered therefrom on to the perforated conveyer-screen 46, which is mounted to travel in a direction parallel to the axis of, and is driven at a slower speed than, the cylinder. The screen 46 conveys the pulp between the lateral plates 59 of a guide-frame 58, and so under the adjustable pressing or condensing rollers 54, the pulp being finally delivered into the feed-trough 67 of the forming-machine &c. D. For the purpose of extracting further moisture from the pulp after it leaves the cylinder B, and to assist in holding the pulp on the screen, a suction-box 68 is mounted below the screen and connected to a suitable exhaust fan, a trap being interposed between the suction-box and the fan, to intercept the moisture withdrawn. The screen is partly supported and prevented from sagging by longitudinal bars 49. The feed-trough 67 projects into the end of the guide-frame 58, which is controlled at that end by a fixed pin 66 engaging the lug 65 on the frame, the opposite end of the frame being connected by a chain &c. 62 to a fixed part 63 &c., to permit the frame to adapt itself to inequalities. The delivery of the web from the cylinder B is ensured by an air blast, which is directed through the slotted pipe 85 against the inner surface of the cylinder. The moving parts of the apparatus and the forming-machine D are driven through suitable toothed and belt gearing, as shown, from the same shaft, and the feed of the pulp from the hopper A is regulated to the speed of the apparatus by means of the governor F, which is operated from the secondary driving-shaft 74 and controls the sliding valve-plates 15 in the outlet of the hopper, the valve-plates being connected through the levers 18, 21 to the rocking-shaft 17 actuated by the governor.

Patent GB-190416602-A (GB)
Title: Improvements in the Manufacture of Bromine Alkyl Acetamides
Filed: 1904-07-27
Granted: 1904-12-31
Abstract: 16,602. Kalle & Co. Dec. 9, A.D. 1903, [date appliedfor under Patents Act, A.D. 1901]. Bromodialkylacetamides of the general formulµ such as bromo-diethylacetamide bromo-ethyl-propylacetamide and bromo-dipropylacetamide all of which possess hypnotic properties without injurious after-effects, are formed either (1) by converting the corresponding acids by means of phosphorus chlorides into acid chlorides, then treating with bromine to form the bromo-dialkyl acid chlorides, and finally treating with ammonia or ammonium carbonate to form the acetamide ; or (2) by treating the dialkylacetic acids with phosphorus and bromine, then with a further quantity of bromine, and finally with ammonia. If diethylacetyl chloride be used, it is gradually heated to 100‹ C. with bromine, the reaction product is distilled, the bromo diethylacetyl chloride formed is dissolved in ether, ammonia is passed through the solution, and the ethereal solution filtered off and distilled. Or, the chloride is allowed to fall drop by drop into an excess of cooled and stirred ammonia. If dipropylacetic acid be used, it is mixed with phosphorus, and bromine is allowed to fall in small drcps into the mixture. When the reaction is completed, further bromine is added during heating, and the product is distilled. The subsequent treatment is the same as in the first example. Diethylacetic acid is converted into the corresponding chloride by means of phosphorus pentachloride, bromine is added, and the product heated on the water bath. Afterwards, the mixture is allowed to run slowly into aqueous ammonia in large excess.

Title: Improvements in the Gearing Mechanism of Slubbing and Roving Frames.
Filed: 1904-07-29
Granted: 1905-02-23
Abstract: 16,708. Tyack, R., and Howard & Bullough. July 29. Slubbing and roving frames.-The swing carrier wheel 1, which gears the jack driving-wheel 2 with the wheel 3 from which the bobbins are driven, is more rigidly supported by a modified construction of the arms 4, 6. The U-shaped arm 6 supporting and covering the wheel 1 is made with solid ends, which are bored out to fit on the bosses of the bearings supporting the shaft 7 carrying the wheel 3, and with bosses serving as bearings for a shaft 8 carrying the wheel 1. The arm 4 is forked at one end to embrace the shaft 8 at each side of one of its bearings. To facilitate the removal of the arm 6, the bearing 11 for one end of the shaft 7 is bolted to the wheel-box 9 across a slot 12, through which the bearing, when unbolted and rotated through a right-angle, may be passed. In this manner, after withdrawing the shaft and wheel, one lug of the arm is released from its boss, and the other lug can then be withdrawn from its supporting-boss. The Provisional Specification describes a development of the invention described in Specification No. 15,720, A.D. 1884, for mounting and supporting one of the planet bevel-wheels which impart a differential motion. According to this, the boss of the wheel is extended on its inner side preferably until it passes beyond the central plane of the torque, thus obviating the tendency to wear and wobble on the shaft, and the length of bearing of the cross-shaft is maintained by retaining the bell-shape of the wheel and dishing out the hole in the bush so as to enclose the boss of, and provide a further bearing for, the wheel.

Granted: 1905-10-26
Abstract: 23,043. Walton, F. J., and Rogers, L. V. Oct. 26. Indicators, departure and arrival.- An automatic time-table for use in connection with the fixed and automatic advertisements described in Specification No. 23,043, A.D. 1904, [Abridgment Class Advertising &c.], is operated as follows :-A lever 2 pivoted at 3 has one side of its lower end formed into a forwardly-projecting bridge 4, provided with an inwardly-projecting pin 5, while the other side of the lower end of this lever has another projecting pin 6. Between these two pins, the upper end of a lever 9, carried on a spindle 10, is held by a weight 7 on the lever 2. Ordinary clockwork 11 drives the spindle 10. The lower end of the lever 9 carries a chain 13, the lower end of which carries a hook 14, sliding in a groove 15. The chain 13 slides between antifriction pulleys 21. Cards 16 are provided, one for each hour of the day, with information as to the times of departure and arrival of each train in each hour, which are to be displayed consecutively for one hour each through the opening a. Wires 19 run along the top edges of the cards 16, and project a little on each side, the projecting pieces sliding in grooves 22, Fig. 2. A portion 20 of the cards is cut away to allow the hook 14 to take hold of the cards. A projection 1 on a wheel 1<a> of the clock f, which rotates once in an hour, on reaching the lever 2 turns it about its pivot 3, thus releasing the end of the lever 9, which at once begins to rotate, driven by the clockwork 11. The catch 24, which is carried by the lever 9, and of which the upper end travels along the camsurface 25 and the other end 24 normally projects through the front of the lever 9, soon gets its end 24 withdrawn, so as to release the weighted arm 26, which then falls about its pivot 27, till it is caught by a catch 28 carried by the lever 9. This impulse. aiding the clockwork 11, causes the lever 9 to revolve rapidly and pull up the chain 13 and one card 16, the wire 19 of which travels along the guide-slots 22, till it gets past the catch 32. At this point the card slips down the inclined slots 22<b>, falls off the hook 14, and takes its place behind the other cards in the curved part of the slot. The lever 9 continues to revolve, till its upper end rests against the pin 5, where it remains till the projection 1 has passed the lever 2, when the levers 2, 9 return to their original positions, the weighted arm 26 being prevented from falling the wrong way by a pin 29. This process is repeated every hour.
