Title: Improved Method of and Apparatus for Indicating Potential in Systems of Electrical Distribution.
Inventor: MERSHON RALPH DAVENPORT
Filed: 1899-07-19
Granted: 1900-06-23
Abstract: 14,908. Mershon, R. D. Feb. 1, [date applied for under Sec. 103 of Patents &c. Act, A.D. 1883]. Current meters.-The pressure between any points of two conductors, supplying alternating current to a single or a distributed load, is indicated at any other point on the circuit by a voltmeter included in a small local transformer circuit, in which inductances, capacities, and resistances are arranged to modify the pressure derived from the near portions of the main conductors as it is modified at the distant points by line resistance and inductance, and especially by line capacity and leakage. In the arrangement shown in Fig. 6, current is supplied from an alternator r through mains a, b to a single load s, the main b having non-inductive and inductive resistances f, g inserted in it. A voltmeter is connected through the secondary of the pressure transformer c to the ends of the series of resistances f, g, and thus indicates the pressure at the alternator, less the fall due to passage of the main current through these resistances. The middle of the series of resistances f, g is connected to the opposite conductor of the voltmeter circuit by a shunted condenser z, u, corresponding to the capacity and leakage between the mains a, b. To compensate in the volt-meter circuit for idle current flowing through the resistances f, g, the ends of this series may be connected through a shunted condenser h, i to the secondary, of a small pressure transformer e, connected reversely ; the shunted condenser h, i represents the line capacity and leakage for this balancing transformer. In modifications, the circuit e, i may be connected directly to the terminals of the volt-meter, instead of to the ends of the series of resistances f, g. The single shunted condenser z, u may be replaced by several, connected between the resistances f, g and the opposite volt-meter conductor, to better represent distributed capacity and leakage. If the load is distributed on the mains a, b, it is represented, similarly to the line leakage, by non-inductive or inductive resistances, the volt-meter being connected between points on the volt-meter circuit corresponding to those in the main circuit between which the pressure is desired to be known. Instead of placing the resistances f, g in the main circuit, the secondary of a main current transformer may be connected to the volt-meter terminals, the volt-meter circuit being thus entirely disconnected metallically from the main circuit. The resistances f, g may be combined. The circuit e, h, i may be replaced by an inductance, when the line leakage is negligeable, and the frequency constant. The transformers c, e may have a common primary winding.

Abstract: 9787. McDonell, J. May 11. Centrifugal flour dressing machines.-In the machine shown in Fig. 1, the reel i is divided by radial partitions into a number of chambers l, in each of which is mounted a beater j carried by a shaft k. The shafts k have their bearings in the ends of the reel a, and on each shaft is mounted a pulley m. An endless band n. passes over all the pulleys m, and is driven at high speed by a superimposed belt o, driven by the pulley p and main driving-shaft h. The .reel itself is driven in the opposite direction at a slower speed by means of the crossed belt e. The materials are fed into a box r, through the bottom of which passes the reel shaft b, mounted on which within the box is a screw conveyer. The materials are thus fed into a narrow space between the double end plates of the reel, from which they pass through apertures into the beater chambers l. The fine materials pass through the silk covering i, and the coarser portions are discharged from the end of the reel in the usual way. A screw conveyer on the shaft h discharges the sifted flour from the collecting- trough t. In the modification shown in Fig. 3 the chamters l are covered with silk i on all sides, and the chambers, together with their beaters and shafts, are readily removable, separate short shafts being provided to carry the pulleys m. Toothed gearing may be used instead of the belts for driving purposes.

Granted: 1902-05-17
Abstract: 10,366. Bertheau, H. A. May 18. Gas or explosive-vapour engines.-The engine is of the four-stroke cycle type, and it can be started, stopped, reversed, or its speed regulated by means of one handle. Carburetting; heating charge.-The carburetter comprises a block 9 having a fourfold passage ; it is heated by the burner which heats the igniting-tube 21, and oil is admitted from a raised reservoir through holes in the seating of an air valve, the air being heated in the helical chimney jacket 26. The carburetted mixture escapes above the cylinder admission valve 20, through which it is drawn with the supplementary air supply entering through ports 21. The suction of the motor piston also opens the oil and air inlet valve to the carburetter. Valves and valve gear; starting; stopping; reversing; speed-regulating.-The valve shaft 14 is placed above the cylinder, and driven by chain gearing 16, 18. It carries a sleeve with a series of five cam swells, III in the middle for holding the exhaust valve open for stopping, II and IV on each side for operating the exhaust valve for forward and backward running respectively, and outside of these, two cams I and V for operating a valve 12 for admitting combustion products from a reservoir, which they entered on each explosion before stopping, and the exhaust valve. The sleeve is adjusted by a handle 37 turning a shaft 36 which carries a toothed wheel 35 engaging a rack 34 on the sleeve. The handle is held in position by a pawl 39 on a spring 40 engaging notches in the horizontal quadrant 41. The pawl is disengaged by depressing the handle which turns about the pivot 43. For regulating the speed, the spring 44 on the admission valve 20 is adjusted by a lever 45 operated by turning the handle about its pivot 43, and so moving a disc 46 which presses on the lever 45. The throttling of the valve 20 causes a richer mixture to be drawn in, which assists in retarding ignition by the heated tube necessitated by a slower speed.

Title: Improvements in or relating to Gas-meters.
Inventor: BOULT ALFRED JULIUS
Filed: 1901-08-09
Granted: 1902-07-17
Abstract: 16,064. Boult, A. J., [Compagnie pour la Fabrication des Compteurs et MatÚriel d'Usines Ó Gaz]. Aug. 9. Meters.-The measuring-device or paddle is constructed so as to balance the interior pressures in the longitudinal direction of the axis, and it is combined with a compensating-device in order to avoid incorrect measurement due to variations in the water level within the meter. The gas enters the meter through the inlet j, passes into a distributing-chamber in the centre of the wheel through the tube i, leaves the latter through peripheral outlets s, and escapes from the meter through the outlet k. The wheel is formed of a double series of compartments, formed of a number of elements each shaped as shown in Fig. 5, namely, having flat or rounded-off surfaces g, g lying in different planes and connected by an inclined surface h. One of the surfaces and the surface h are provided with a circular rim r. Several of these elements are combined to form the two adjacent halves of the wheel, being soldered around their circumference at v. The partitions in one half are, however, inclined in an opposite direction to those in the other, so that the pressures exerted by the gas upon those walls are opposed, and therefore equalize one another. There is a contraction q in each plate, by means of which the capacity of the wheel is not very sensibly influenced by variations in the water level. The compensating-device for variations in the water level consists of a smaller drum b, divided into a large number of compartments by means of partitions c, and mounted upon the same shaft o. Some of the gas from the wheel passes through the communicating-tube l to the compensating-drum, and thence back to the central distributing-chamber in the wheel by the tube i. As any alteration in level affects both wheels alike, the measuring is not influenced by the variation in height of the water line. The compensator may be arranged within the wheel itself, partially in and partially outside the wheel, or between the two drums constituting the wheel. The compensator may be used with an ordinary meter drum, such a combination being illustrated ; or the wheel may be used with another compensator. The whole device may be used as a motor for raising water.

The form shown in sectional plan in Fig. 2 comprises a buffer rod f, which slides through the headstock e of the vehicle and is provided with a spring m adapted to take ordinary shocks. Between the buffer guide a, b and the buffer rod slides a sleeve k, of which the inner flanged end k<1> bears against an additional spring w enclosed in the buffer guide. The position of the front end k' of the sleeve is so arranged that the spring w only comes into play under exceptionally great shocks. Each spring consists of concentric rubber rings g spaced apart by a perforated metal plate i and arranged side by side in sets separated by metal plates h. In modifications, the sleeve may be flanged at both ends, the buffer guide being then formed in two parts bolted together, or only the outer end of the sleeve may be flanged, the inner end being screwed into or butted against a plate.
