Title: Improvements in and relating to polyphase rectifiers
IPC: H02M7/06
Filed: 1932-08-10
Abstract: 409,759. Rectifying alternating currents. AKT.-GES. BROWN, BOVERI, ET CIE, Baden, Switzerland. Aug. 10, 1932, No. 22420. Convention date, Aug. 10, 1931. [Class 38 (ii).] To obtain equal current distribution to the anodes of a polyphase rectifier, fed from a transformer which comprises n 6-phase star windings, n being an integer greater than one, the windings of the feeding transformer are so interlinked by interphase transformer windings that the phase angle between the voltages induced in the interphase windings associated with successively burning anodes compensates for the phase angle between the secondary windings of the feeding transformer connected to successively burning anodes. A 12-anode rectifier G, Fig. 1, is fed through a transformer T, which comprises two secondary star windings connected to the anodes through the primary windings P1, P2 respectively of interphase transformers D1, D2. The star connected secondary windings Q1, Q2 of the interphase transformers are connected together as shown, and the windings Q2 are compounded to compensate for the phase angle of 30‹ between the voltages in successively burning anodes. In a modification, the primary bindings P1, P2, Fig. 2, of the interphase transformers are connected between the secondary windings and the star point of the feeding transformer. The delta connected secondary windings Q1, Q2 are connected together and the windings P2 are compounded. In further modifications, interphase windings are connected between the secondary windings and the star point of the feeding transformer and are arranged on a threelimbed core. An additional delta connected winding may be provided on the core to reduce leakage.

Coupling-devices.- Relates to communicating or connection means between vessels, such as sub. marine vessels, whereby the distance apart is indicated automatically and a telephone connection is maintained. It consists in a wire b passing into the. hulls of the vessel U at the points k, and kept taut by the strain placed upon the wire within the vessels, acting in conjunction with a buoyant body i attached at the centre of the span. In each ship a roller a is wound with the wire, which may te covered multi-strand, copper or other suitable insulated conducting wire, and is connected by means of a wire c, arranged to admit of rotation with a telephone. The communication wire b passes over a guide eyelet e to a grooved measuring-wheel f which it rotates, and thereby actuates a counter g, g<1> registering the length paid out. Preferably, the drums are rotated by springs as the ships approach, so as to take up the slack automatically, or a motor may be employed for the purpose. Water-tight passages are arranged at the points k where the wire penetrates the hulls.

Abstract: 248,016. Invernairn (W. Beardmore), Lord, and Chorlton, A. E. L. Sept. 24, 1924. Regulating delivery by closing suction and delivery valves.-Fuel is delivered by a pump plunger A reciprocated directly from the engine work shaft E to one of two fuel injectors on each alternate forcing stroke, through a distributing valve C reciprocated by an eccentric G<2> driven at half crank shaft speed by gearing E<2>, E<3>. The constricted portions F<4>, F<5> of the valve C alternately place the delivery pipe D<3> of the pump in communication with one or other of the pipes H<1>, H<2> leading to the fuel injectors. Fuel is delivered to the pump from a tank N by a gear pump N1 which is driven from the crankshaft by gearing E<2>, E<3>, E<4>, E<5> and which supplies an air bottle N<3>, both the pump N<1> and the air bottle being common to a series of three pumps D, each supplying two cylinders. The fuel passes from the air bottle N<3> to the pump chamber D<1> through a suction valve B which returns fuel back to the air bottle N<3> at the beginning and end of the forcing stroke of the plunger A. The valve B is reciprocated from the plunger A through an eccentrically mounted lever K, and comprises two constricted portions J<3>, J<4> separated by a boss K<3>, and in communication with one another through a central passage J<5>. The constricted portion J<4> is always in communication with the air bottle N<3> and serves to connect the pump chamber D<1> with the source of fuel supply at the lower end of the stroke of the plunger A, wherein the constricted portion J<3> connects the chamber D<1> with the air bottle N<3> at the upper end of the plunger stroke. Injection takes place while the central boss K<3> of the valve B is passing the port J<2> leading to the pump chamber D<1>. In order to vary the quantity of fuel injected the boss K<3> is made of varying axial length, and the valve B is adapted to be rotated by means of a handle K<4>. The timing of the injection period relatively to the position of the engine piston may be varied by means of the eccentric K<1>. The fuel injector L<1> comprises a series of converging orifices M<1>, controlled by a fluid-actuated valve M<3>.

Filed: 1945-09-05
Abstract: 606,435. Reinforced concrete, floors, and beams. CHRISTIN, J. S. Sept. 5, 1945, No. 22884. [Class 20(iv)] A reinforcement member for use in concrete beams comprises a longitudinal flange or foot 1, and a web consisting of a continuous rib 2 and, tongues 2b, 2c projecting therefrom, the tongues being secured to the foot 1 by welding. The rib and tongues are formed by cutting a metal strip along the line 9, Fig. 3, to form two webs having tongues, 2b, 2c, slits 10 on the edges of the ribs 2 permitting the formation of oppositely turned flanges 7, 8. The tongues 2b, 2c may be bent alternately in opposite directions to form faces 5 which are spot welded, as at 6, to the flange or foot 1, or alternately, the member 1 may be of T-section, the tongues 2b, 2c being, in that case, welded alternately to opposite sides of the vertical web of the T-section. Tongues 2b, 2c, as in Fig. 1, or with the faces 5 directed inwardly, may be bent outwardly alternately on opposite sides of a longitudinal central plane at right angles to the member 1, so as to lie in inverted V-formation, these constructions being suitable for use when the lower part of the flange 1 is to be outside the concrete. In another form, the tongues have a slope in the direction of the length of the reinforcement, and the flanges 7, 8 are replaced by a longitudinal head formed in the rib 2. The tongues may be arranged without longitudinal slope and in inverted V-relation, but the edges of the tongues may be inclined so that the tongues are wider at their free ends than at the ends joined to the rib 2. In a further form, a double T-iron having a very thin and deep web is cut in the manner shown in Fig. 3, except that the tongues have a slope lengthwise of the reinforcement, to form two webs comprising a T-sectioned rib and tongues projecting therefrom which latter are welded to a stiffening bar, angle iron, or flat or beaded strip.
