Abstract: 17,838. Vandervell, C. A., and Midgley, A. H. Aug. 1. Exciting.-A self-regulating dynamo for train and car lighting &c. comprises main poles a, Fig. 1, each of which is provided with an ordinary shunt or series exciting-winding c or with a constant excitation, and supplementary poles b, each of which is excited by a winding d connected between a main brush e and a supplementary brush f.

In one arrangement, the ball bearings between the hub and axle end are formed of different internal and external diameters for opposite sides of the vehicle. Figs. 4 and 5 show another arrangement in which projections n, n<1> on the left and right permanent hubs respectively are so shaped and disposed relatively to collars m, m<1> on the corresponding axle ends that it is impossible to interchange the parts. In Figs. 6 and 7, nuts p, p<1> for the left and right axle ends respectively have different types of thread and are adapted to coact with bearing- retaining rings g<2>, g<3> also with different types of thread, so that a left-hand hub b cannot be interchanged with a right-hand hub b<1>. The nuts p, p<1> may be arranged to co-operate with suitably-shaped recesses in the hub end instead of with the rings g<2>, g<3>. In the case of a driving-axle, the axle ends for opposite sides of the vehicle are different and means are provided, such as differences in the connexions to the chassis, to make it impossible to interchange the left- and right-hand axle ends, and it is also made impossible to interchange the hubs by providing the driving-pieces with a different number of dogs on opposite sides of the vehicle. The permanent hubs may also be distinguished by attaching in a distinctive manner brake.drums of different configuration adapted to co-operate with corresponding drum-casings which must in turn be attached in a distinctive manner to the vehicle.

Abstract: 13,903. Siemens & Halske Akt.-Ges., Bangert, K., and Utecht, E. June 16. [Addition to 9499/12.] Rontgen-ray apparatus.-In a modification of the method described in the parent Specification for exciting the Rontgen-ray tube by suddenly commutating a direct current flowing in the primary windings of a transformer or induction coil, changes are effected in the primary circuit simultaneously with the commutation by which the value of the time constant is reduced, and in order to obtain a more rapid rise of the commutated current and a more effective induced electromotive force. In one method, only a portion of the primary p, Fig. 2, between the terminals a, c is utilized on reversing the current by the switch k. The whole of the primary winding may be introduced into circuit by an auxiliary switch u, Fig. 3, which may be moved automatically from the reversing- switch k. The transformer may, alternatively, be provided with two primary windings having different time-factors. A non-inductive resistance v is included in the commutated primary circuit, and may be gradually cut out automatically by the commutator switch.

Abstract: 21,154. Cahill, D. Sept. 19, 1912, [Convention date]. Spray carburettors.- A rich mixture formed in a comparatively small chamber is admitted, past a needle valve actuated by the throttle valve, into the induction pipe, where it mixes with the main air supply. The main air passage may therefore have a sectional area greater than usual. Fuel from the float-chamber a is sprayed through the nozzle i<1> into a chamber h<1>, to which air is admitted through a small orifice. The rich mixture issues through the passage h, controlled by the needle valve j', into a chamber g<3> where it mixes with hot air entering by the pipe b, Fig. 5. The resultant mixture then enters a perforated tube f which is co-axial with a conical throttle valve c which controls the main supply of air entering at d', and the mixture leaving at d<2>. The tube f is covered with gauze kept in position by a spring f<3>, the fuel being removed from the gauze by the air current. The needle valve j<1> extends through the throttle spindle at j<0>, and is actuated by the throttle through an interchangeable cam l and bell-crank lever l<1>, but may be actuated independently of the throttle by a connexion l<4>, Fig. 4. Fuel may be entirely shutoff and air only admitted to the engine, or a small amount of mixture may be admitted, when the throttle is closed, through an orifice e<3>, Fig. 5. The wire gauze on the tube f prevents flame from reaching the fuel-chamber. Liquid fuel which accumulates in the tube f facilitates starting and accelerating. The, spraying-chamber h<1> is provided with an inspection cover a<4>, and also with a manometer by means of which the rate of flow of fuel may be indicated to the driver of a motor-vehicle or aeroplane. The chamber h<1> may be at some distance from the induction passage and connected to it by a heated pipe.
