Title: Method and Apparatus for Producing a Desired Distribution of Magnetic Flux in Motors, Generators and other Electrical Apparatus.
Inventor: MERSHON RALPH DAVENPORT
Filed: 1907-02-19
Granted: 1907-10-24
Abstract: 4175. Mershon, R. D. Feb. 19. Electro-magnets ; dynamos and motors, alternating-current ; field magnets.-In order to obtain any desired distribution of magnetic flux, for example in the stator of a motor or generator, currents are fed into the winding at points so chosen as to produce component fluxes, which combine to produce the required resultant flux distribution. Fig. 1 represents a 2-pole gramme ring winding for the stator of a single-phase induction motor, into which current is fed at the ends of an electrical diameter a, b, producing the flux distribution shown by the lower curve w<2>, Fig. 4<a>, in which ordinates represent flux density and cd represents 180 electrical degrees, the maximum flux density occurring at the feeding points a, b, Fig. 1. If currents are fed in at two points per pole, as at g h, i j, Fig. 2, the distribution shown by the middle curve w<3>, Fig. 4<a>, results, the flux density being uniform between the points g, h, as there is no current flowing in that portion of the winding. By combining the arrangements shown in Figs. 1 and 2, that is by feeding at three points per pole, the flux distribution shown by the upper curve w<4>, Fig. 4<a>, which is the sum of the curves w<2>, w<3>, results. By increasing the number of feeding -points per pole, the number of components, as w<2>, w<3> is increased, and by suitably choosing the number of feeding points and the strengths of the currents fed into them, any desired resultant, for instance an approximate sine distribution of flux, maybe obtained. The feeding points may be connected in pairs to the secondaries of a transformer having as many secondaries as there are pairs of feeding points, as shown in Fig. 2, or balancing-coils may be connected across the points g h, ij, Fig. 2, the centres of the balancing - coils being connected to a source of supply, such as the secondary transformer. The invention may be applied to drum windings, and also to single and polyphase induction and svnchronous motors and generators, and to other electrical apparatus.

Patent GB-190727024-A (GB)
Title: New or Improved Apparatus for Automatically Opening and Closing Valves.
Filed: 1907-12-06
Granted: 1908-04-23
Abstract: 27,024. Aktiebolaget Gasaccumulator. Dec. 7, 1906, [date applied for under Patents Act, 1901]. Extinguishing gas.-Gas lamps, such as buoy and lighthouse lamps, are extinguished in broad daylight by the unequal expansion of two or more solid, liquid, or gaseous bodies under the influence of radiant beat. The two bodies, or their envelopes are made with a reflecting-surface and a radiantheat absorbing-surface respectively, or one of the bodies is screened from radiant heat, the bodies being mechanically or electrically connected to a valve or the like in the gas conduit. In one form of apparatus, a central metal cylinder 1, Fig. 1, coated with absorbent material, is mounted by pins 9, 10 or the like between a movable upper part 4 of a valve-lever 7 in a valve-box 6, and other cylinders 2, formed with reflecting-surfaces and concentrically arranged round the cylinder 1, are mounted between the plate 4 and the valve-box 6, so that, on the cylinder 1 expanding more than the cylinder 2 under the influence of radiant heat, the valve is closed in opposition to a spring 7*. The cylinders 1, 2 may be protected by tubes 11, 12, and the plate 4 and the valve-box may be faced with insulating-plates 13, 14. A spring 17 is inserted between the pins 9, 10, and a spring 16 bears on the top of the movable plate 4. When greatly heated, the cylinder 1 can expand vertically independently of the pin 9. In a second form, two vessels A, B, Fig. 3, formed respectively with absorbent and reflecting-surfaces are connected by a pipe C having a mercury or other index D, which, when the air in the vessels is equally or unequally expanded, connects one of two pairs of contacts 22, 23, 20, 21, so that a valvelever 28, consisting preferably of a permanent magnet, opens or closes a gas exit 33 under the action of electro-magnets 30, 36, one of which forms part of the gas exit. Contacts 31, 32, against which the ends of the lever bear in their raised positions, are connected to the contacts 20, 22 by coils passing round both electro-magnets, and the valve-lever 28 is connected through the battery to the remaining contacts. Porous or granular plugs prevent the index D from moving too far each way. In a third form, the gas valve 42, Fig. 4, is operated by the relative expansion of the gas in two chambers 39, 38 acting through diaphragms 42, 40, the chambers 38, 29 being enclosed by opaque and transparent casings 47, 48. The expansion of mercury in pipes may also be employed for the same purpose or the apparatus shown in Figs. 1 and 2 may be employed for electrically operating valves.

Title: Improvements in System of Dispensing Liquids.
Inventor: BOWERS JAMES
Filed: 1908-01-21
Granted: 1908-10-15
Abstract: 1418. Bowers, J. Jan. 21. Direct air-pressure apparatus.-Comprises means for cleaning the pipes of liquid-dispensing systems of the type wherein liquid is raised or forced from a receptacle by pneumatic pressure. Fig. 1 ill,ustrates the system as applied to dispensing beer. The beer is forced from barrels 5 by compressed air admitted from a main 13 and pipes 14, 15, and passes through valve casings 71 and pipes 8, 10 to faucets 11 behind the counter. The valve casings 71 are connected by pipes 21 to a water-supply main 22, and contain double - seated valves 77, Fig. 3, which are normally held in their upper position, in which the beer has access to the pipes 8, 10 while the water is cut off, by cords 35 connected to rings 36 hooked on pegs beneath the counter. Weights 50, or in an alternative form springs, are attached to the valve-spindle 78 so as to tend to close the valve on its lower seat. Before cleaning the pipes, the beer in them is allowed to run back into the barrels by connecting the faucets 11 to the air-supply pipe 13 by means of a flexible connecting-pipe 19, whereupon the rings 36 are released and the water is thereby allowed to flow through the pipe 10. In the modified form of valve shown in Fig. 11, the valve 77 is operated by air pressure acting against a piston 44 mounted on the valve-spindle, but is normally held in its upper position by the pressure of the beer or other liquid to be raised. A spring 45 serves to press a cupleather 46 against the piston, and also to compress the lubricating and packing material 48, consisting of layers of chamois skin treated with graphite.
