Title: Improvements in the Control of Alternating-current Motors and in Apparatus therefor.
Filed: 1904-12-02
Granted: 1905-11-02
Abstract: 26,290. British Thomson-Houston Co., [General Electric Co.]. Dec. 2. Motors, controlling.-Relates to a controller for an alternating-current commutator motor whereby it is caused to start as a repulsion motor and at speed operates as an induction motor. Reference is made to Specification No. 4771, A.D. 1904. The switch has two movable contact-members, one of which closes the stator circuit and the other closes the circuit between two brushes when a certain speed is reached. As shown in Fig. 1, the rotor B is provided with a pair of permanently shortcircuited brushes b<1>, b<1> inclined to the magnetization axis of the stator A. The second pair of brushes b<2>, b<2> may be connected through a small portion of the stator winding, or directly, to the coil C, and also to the two contacts f. The switch consists of a pivoted arm D and a loosely-pivoted arm E, which rests against the arm D and is operated by it to open the switch. When the arm D is moved to engage the contact d, the stator circuit is closed, and the motor starts as a repulsion motor. The induced electromotive force between the brushes b<2>, b' causes a current to flow round the coil C, which then attracts the armature e, and holds the arm E against its poles. As the motor speeds up, another and opposite electromotive force is induced between the brushes b<2>, b<2> by the conductors cutting the primary field. The current in the coil C then falls, and releases the arm E at the desired motor speed. The arm E falls, and the block F bridges the contacts f, short-circuiting the coil C, and also short-circuits the brushes b<2>, b<2> through the small portion of the stator winding, which is thus able to impress a compensating electromotive force on the brushes b<2>, b<2>. A modification is shown in Fig. 2, in which the stator winding is in two parts, which are connected first in series and then in parallel by the switch arm D. The brushes b<2>, b<2> are short-circuited directly, instead of through the stator coils.

Title: Improvements in Reversible Seats
Inventor: BAYLOR ARMISTEAD KEITH
Filed: 1904-12-05
Granted: 1905-10-05
Abstract: 26,483. Baylor, A. K. Dec. 5. Seats and seat backs.-Relates to that kind of reversible seat for tramway and like vehicles in which the seat bottom tilts to a suitable inclination as the back is reversed. The seat bottom 2 carries bearings 6 which rest upon pins 5 projecting inwards from cross-bars 4 carried by supports 3, which are secured to the fixed endframes 1. The back frames 11 are pivoted at 12 to the inner side of the frames 1 and carry seat backs 10 which can oscillate about pivots 13, the amount of motion being limited by the engagement of pins 14 with slots 15 in the frames 11. When the back is reversed, one pair of the projections 16 on the frames 11 comes into contact with one pair of cam-plates 8 fixed to the seat bottom, causing that end of the seat to tilt until it rests upon blocks of rubber 7 carried by the supports 3 ; the weight of the sitter will then cause the parts 16, 8 to interlock. In modifications, the back frames 11 may be pivoted on the outsides of the frames 1, the interlocking members 8, 16 being suitably modified; and the pins 5 may be carried by the seat bottoms, the bearings 6 being secured to the cross bars 4.

Granted: 1905-10-05
Abstract: 4959. Abel, C. D., [Akt.-Ges. f³r Anilin- Fabrikation]. March 9. Theobromine derivatives; salicylates.-A soluble compound of theobromine is prepared by treating barium theobromine with an alkali salicylate, or by treating sodium theobromine with an alkali salicylate in presence of a soluble barium salt, or barium salicylate may be made to react with alkali salicylate and sodium theobromine. The best proportions are four molecular parts of the salicylate to one molecular part of barium theobromine or equivalent thereof. The product, except for impurities, appears to be identical in all cases, and is a white powder easily soluble in water. Its solution gives a precipitate of barium carbonate with carbon dioxide, and a violet colouration with ferric chloride. With chlorine it yields a yelloworange precipitate soluble in caustic soda.
