Title: Improvements relating to Electric Voltage Regulation.
IPC: H02P9/24
Filed: 1910-09-09
Granted: 1911-06-08
Abstract: 21,041. British Thomson-Houston Co., [General Electric Co.]. Sept. 9. Regulation, automatic systems and apparatus for.-A booster-generator is connected in series with the exciter of a main generator, and a Tirrill regulator is employed to vary simultaneously the field of the exciter and the booster. A generator 1, Fig. 1, is connected to a load circuit 2, 3, 4, and its field core 5 is connected to the exciter armature 8 and the booster armature 9, both armatures being on one shaft. The contacts 14 controlled by the relay magnet 15 are in a shunt circuit round the resistance 12 in series with the exciter field coil 11. The booster has two opposing field coils 17, 19, and the resistance 20 in series with the coil 19 may be short-circuited by the contacts 22 controlled by the relay magnet 24. The relays 15, 24 are wound differentially, one winding in each case being connected permanently to the exciter mains 6, 7, and the other winding being connected to the exciter mains through the contacts 31 of the main regulator. These contacts are controlled on one side by the coil 38 across the exciter mains, and on the other side by the loadcircuit current and voltage coils 37, 39. When the voltage falls below normal, the winding 25<a> of the relay 15 is energized, and the current in the field coil of the exciter is increased. At the same time, the winding 28<a> of the relay 24 is energized, and the current in the field coil 19 of the booster is diminished. The booster field is therefore increased as the current in the coil 17 is unchanged. The exciter and booster thus combine to increase the field of the generator 1. When the voltage rises above normal, the reverse action takes place. In a modification shown in Fig. 2, the booster has one field coil 48, and is driven by a shunt motor 43. The field strength of the booster is varied simultaneously with the field strength of the exciter, so that the two machines aid each other. In a further modification, the resistance in the field circuit of the motor 43 may be cut in and out by a relay at the same time as the exciter and booster field resistances are cut out or in. Specification 14,701/08 is referred to.

Granted: 1912-02-15
Abstract: 8821. Lake, W. E., [United States Light and Heating Co.]. April 8. Electrodes f o r lead accumulators. A PlantÚ positive or negative electrode is made from a blank by applying pressure very gradually and substantially at rightangles to the surface so as to raise compact projecting ribs of metal having a comparatively fine uniform crystalline structure, without disrupting the surface. This may be effected by the repeated action of oscillating pivoted blades 2, Fig. 6, which project beyond spacing-plates (not shown), the metal being forced up between the blades 2, as these are brought gradually nearer together, so as to form ribs 5, Fig. 3, which are rendered compact and even by abutting against the spacing-plates. The ribs 5 are united by cross ribs 6 produced by notches in the blades 2, and if blunt blades are used, the upper and lower sets may finally be brought together, forming slots between the ribs 5, as shown in Fig. 4, which allow circulation of the electrolvte. The radius of the blades 2 is sufficient to cause a nearly normal pressure on the lead. The electrodes may be made in the machine described in Specification 8814/11, [Class 83 (iv), Metals, Working].

Abstract: 20,142. Brown, J. Sept. 12, 1910, [Convention date]. Radial-flow type; plant; driving and transmission mechanism, special applications of; reversing.-Three combined inward and outward flow rotors 1, 3, 5, Fig. 3, for forward driving and three similar rotors 2, 4, 6 for reversing are arranged in a single casing with their axes parallel. Each rotor shaft 8, Fig. 4, is geared to a common gear-wheel 9 mounted upon the main shaft 10. Each set of rotors runs idle alternatively according to the direction of rotation. In a modification, the idle rotors are thrown entirely out of gear. Working - fluid supply.-The turbines are supplied with products of combustion through a central oscillating-tube valve 24, Figs. 3 and 4, attached to a spindle 33. There are two concentric combustion chambers 58, 56, Fig. 4, which are respectively supplied with gas through pipes 60, 73, controlled by valves 62, 74. Communication between the two combustion chambers is controlled by an oscillating tubular valve 57 attached to a sleeve 68. The valves 24, 57, 62, and 74 are actuated off the main shaft cam and gear mechanism, the valve 24 being set by hand relative to the gear so as to permit alternatively either direction of rotation. The method of working is as follows: A charge enters the central combustion chamber through the valve 62, thereby scavenging it, whereupon the valve 74 closes the connexion between the two chambers. The valve 74 thereupon opens and the outer combustion chamber is filled with gas. The valve 62 then closes and the charge in the inner chamber is ignited, whereupon the valve 57 is opened and the exploded charge enters the outer chamber and ignites the large charge therein. At this instant the valve 24 admits the products of combustion to the turbines, after which the above cycle of operations is repeated. The fluid after performing its work is passed into an exhaust chamber 23.
