Abstract: 10,609. Allgemeine Elektricitõts Ges. May 4, 1912, [Convention date]. Systems depending on the use of two or more machines.-An automatic arrangement for maintaining in phase the currents of a number of parallel-connected alternators comprises a phaseresponsive instrument controlling the excitation of each alternator, these instruments being brought into operation by a phase displacement between the equalizing-current and the current of the out-ofphase alternator. In the arrangement shown in Fig. 1, the secondary windings of current transformers 1, 2, 3 are placed in closed circuits k containing operating-coils b and resistances w, the primary windings of the tranformers being placed in the corresponding phases of the several alternators. The closed circuits k are connected in parallel between equalizing-leads 4, 5, operating- coils a being connected between the lead 4 and a point between the coils b and resistances w. In a modification, the coils a are connected between the lead 4 and a point between the coils b and the transformer secondaries. In a further modification, the resistances w are dispensed with. In the modification shown in Fig. 4, the coils a are divided into two parts a', a<2> arranged on each side of the closed circuits k. In the modification shown in Fig. 5, the transformers are replaced by resistances r, the coils b being placed across these resistances and the coils a between the equalizing-lead 4 and the points of connexion of the resistances r and coils b. In the modification shown in Fig. 8, the secondary windings s and coils b are placed in a closed polygon, the resistances w in a similarly closed polygon, and the coils a in connecting-leads between the two polygons. In a modification, the resistances w are replaced by the coils a, and in further moditications, the polygon without the resistance, w is replaced by an open equalizing-conductor, an annular conductor, or a point. The coils a, b are arranged to operate on a rotatably-mounted disk 7, Fig. 7, against the action of a spring 8, the contact arm 11 controlling the operation of a resistance-controlling motor or any other form of regulator.

Filed: 1913-07-03
Granted: 1914-07-03
Abstract: 15,379. Pictet, R. P. July 3. Pottery; pottery materials. - Retort or furnace tubes or chambers are made from a paste which is prepared from powders of highly-refractory materials mixed with chemically prepared carbon obtained in atomic or molecular condition by the dissociation of hydrocarbons or carbonaceous material. The materials are mixed with a suitable liquid and moulded into the desired form, for instance in an hydraulic extrusion press, and the tubes or chambers so formed are fired in a reverberatory furnace, heated by water-gas and oxygenated air, at a temperature sufficient to soften the paste, but not as high as to produce deformation; or they may be heated by an electric current passed through them. The refractory material may consist of finely powdered silica, magnesia, alumina, lime, carborundum, or calcium carbide, and the carbon may be obtained by the dissociation of methane (CH4). About 30 per cent of carbon is a suitable amount. The liquid used for making the paste may be alcohol, chloroform, petroleum, or water. Tubes or chambers so produced are especially suitable for use in furnaces for the production of hydrogen or hydrogen mixtures from hydrocarbons at a high temperature.

Abstract: 16,453. Bernier, H. B. de, and Eyres, N. T. July 17. Four-stroke-cycle engines; driving-gear.-In an engine of the type in, which the cylinder reciprocates in order to give a reduced clearance on the exhaust stroke, the compression space is variable. The reciprocating cylinder e has projections n which work in segmental slots o in a freely-oscillating ring p. The ring p is housed in a recess in a screwed ring r, the vertical adjustment of which controls the travel of the cylinder e in order to vary the compression. The cylinder e is reciprocated by a lever 14 which is actuated by an eccentric 15 on a shaft 16, revolving at the same speed as the crank-shaft; the fulcrum of the lever 14 is formed by a cam 21 on a shaft 25 revolving at one-fourth the speed of the crank-shaft. The cam 21 is out of contact with the lever 14 on the compression and firing strokes, and consequently the cylinder c is stationary in its upper position on those strokes. To vary the compression the ring r and the driving-gear of the cylinder e are simultaneously adjusted. The shafts 16, 25 are supported on a bracket 27 loose on the shaft 17, and are adjusted by a screw 29 working in a nut 30 which is actuated from a shaft 33 carrying a friction wheel 34, capable of engagement with either of oppositely-revolving friction wheels 35, 36. A shaft 40 driven from the shaft 33 drives a shaft 41 carrying a cam y, which reciprocates a rod w fitted with a double pawl v. Upon the upper edge of the ring r are oppositely-directed series of ratchet teeth, adapted to be engaged by one or other end of the double pawl v. The pawl v is put into action by hand simultaneously with the adjustment of the shaft 33 to engage the wheels 35, 36. The cylinder e has' ports f, g which cooperate with ports in a sleeve driven from a half-speed shaft 10, and with ports h, i in the main cylinder a to control inlet and exhaust.

Abstract: 23,626. Fleming, F. A. Oct. 18. Apparatus with jointly-controllable drums; driving-gear; regulating and control-transmitting gear.-Relates to double-barrel windlasses for raising, lowering, and transporting loads suspended by two cables passing separately over pulleys at the head of two derrick arms, and comprises arrangements of clutches and of their operating-mechanism. In the form shown in Fig. 1, the ropes are led in opposite directions round two loose barrels. The barrels are connected by an interposed epicyclic train, of which the planet-carrier can be regulated by a brake 8. The other ends of the drums are formed with clutch surfaces co-operating with similar surfaces on slidable spur-wheels 9, 10 driven from a countershaft. The brake 8 and the spur-wheels 9, 10 are controlled by a hand-wheel 18 operating a shaft carrying three cams 19, 20, 21. For lifting or lowering, one clutch is engaged and the brake applied to drive the drums in opposite directions, while for transporting the load, both clutches are engaged to wind in one rope and pay out the other. In a modification, Fig. 6, the two clutches are arranged on the first-motion shaft and drive the barrels, one directly, and the other through a reversing - train. A double - clutch member 48 is interposed between clutch members on the drums 1, 2 and can be slid along to clutch the drums together. The clutches are operated by pins engaging cam-slots 33, 49 in a plate operated by a hand-lever 26 through a rod 31. Fig. 8 shows a modification of Fig. 1, in which the spur-wheels are slid into engagement with the drums by a cam-plate 32 operated through the rod 31 from the lever 26. The brake 8 is operated by a pedal 39, but this can only be effected when the lever is in an end position owing to a projection 42 on the pedal being above a pin 43 on the lever 26. The brake can also be operated by arms 36, 37 on the rod 31 engaging pins on a plate 40 carried by the shaft 38. A pawl 44 prevents reversal of the lever 26 until it has passed the end position.

Abstract: 4351. Brooke, R. G. Dec. 30, 1912. Direct a i r or s t e a m pressure apparatus, automatic.-In apparatus for discharging liquids from a system working under a vacuum, a differential piston is used, which, in one position connects a receiver with the system so as to equalize the pressure, and in the other position closes this connexion, and admits steam or other fluid to discharge the liquid. In the trap, shown in Fig. 1, for use with oil separators, a float in a receiver c, having inlet and outlet valves b, a, rises by accumulation of liquid and opens a valve 14 to connect one end n of the differential piston with the atmosphere or other source of pressure through a passage 22, so as to close the connexion 10 between the receiver and the system being drained, and establish at 25 communication between the receiver and the atmosphere to discharge the trap. When the float falls, the valve 14 is closed, and air leaks past the piston to the vacuum passage 10, and the piston is moved to the position shown by the atmosphere acting on the other end; k. In the trap shown in Fig. 2, for use in systems in which the pressure may vary from vacuum to above atmosphere, the valve 14 is operated by a bucket d.

Abstract: 21,771. Bambridge, W. G. Oct. 30. Drilling-machines.-In a machine for drilling rock, stone, metal, &c., and of the kind in which the tool spindle is driven from a motor, preferably an electric motor, through planetary gearing, the planet-pinion carrier is normally held from rotation by a frictional clamp, but may slip back during excessive load on the tool, so that the speed of the tool spindle maybeautomatically varied according to the variation of the resistance, without varying the speed of the motor. The drill 4 is feathered to a steel sleeve 3 carrying the internally toothed ring 24 of an epicyclic gear, the planet-pinions 21 of which are mounted on the flange of a brass sleeve 2. The drive is communicated from the motor 15 through a pinion 17 and gears 18, 20 carried by a bush 19 loosely mounted on the sleeve 2. The sleeve 2 is normally held from rotation by a spring band 25, the tension on which is adjusted by a nut 30; but when abnormal resistance is encountered, the sleeve 2 can rotate and so reduce the speed of the drill, while maintaining the speed of the motor constant without overloading. A spring may be provided between the nut and washer 31 to take up wear. The spring band may be replaced by a clamp consisting of a collar, block, &c. formed in sections and clamped to the sleeve by bolts and nuts, with springs to take up wear. The feed is imparted by a two-part nut 7 hinged at 8 on a spring cap 9, which is frictionally held on a brass cap 14 on the end of the bearing 1 by an adjustable tightening-strap 10 so as to vary the feed.
