Abstract: 12,464. Lake, H. H., [International Ore Separating Co.]. May 31. Magnetic separators. - A separator for use in treating finelydivided ores is provided with a hopper 60, whence the ores pass to an oscillating tray 33, which conducts them beneath the poles of a series of magnets 100, 110, 120, successively increasing in magnetic power. Beneath the hopper 60 is a box 70, which slides upon rods 63 and is actuated by means of links and levers from a countershaft. The lower part of the box is an inclined shoot 72, having upturned edges, and adapted to feed the ores in an even layer upon the tray 33. The discharge side 75 of the box 70 is formed with a series of slots 77, the discharge through which is regulated by means of an adjustable slide 78. The tray 33 is attached to a frame 31 pivoted at 32 to a bracket 30, and has its lower end supported by links 36 or equivalent means, which allow the tray to be oscillated laterally by means of a crank and connecting-rod. Side flanges 34 and an end flange 35 are fitted to the tray, the bottom of which is preferably made of aluminium, or aluminium supported by a light structure. The flow of material towards the magnets is regulated by means of three sets of adjustable shutters, one set being arranged in front of each magnet ; these shutters are fitted between the bottom of the tray and bars secured to the flanges 34. Carriers or endless bands 20<b>, 21<b>, 22<b>, one for each magnet, are supported by pulleys 20<a>, 21<a>, 22<a> respectively, and serve to transport the separated material to suitable hoppers. Each magnet 100, 110 comprises a series of spaced parallel bars secured to plates 102, which are attached to vertically-adjustable bars. Brass or other suitable plates 105, 115 are secured to the cores of the magnets 100, 110 respectively, and press slightly upon their respective carriers or endless bands. The horse-shoe magnet 120 is made in two parts, connected together by links 122, the rear part being adjustable by means of bars 144. The upper part of the magnet is independently adjustable by means of an arm 147 secured to the upper part of the magnet, and adjustably attached to a bolt 149. The ends of the bars forming the upper part of the magnet are recessed to form a series of fingers 127 alternating with spaces, and a sheet of brass or other suitable material is secured to the ends of the bars. A keeper 140 is secured to the ends of the bars of the lower part of the magnet, and may be adjusted by means of screws 143. Blows of variable intensity are delivered upon the endless bands or carriers by means of a bar or beater actuated from the oscillating-tray 33. During the separating operations, the magnet 100 first separates the most magnetic material, the magnet 110 next separates less magnetic material, and the magnet 120 finally separates the least magnetic portions.

Abstract: 6405. O'Donnell, J. P., and Potter, H. S. March 16. Dusting-appliances; cleaning; cleaning fabrics. - An apparatus for extracting dust from carpets, fabrics, &c. is mounted on a motor tricycle, Fig. 4, and comprises a pump 14 which supplies compressed air to an extracting-tool, dustladen air being conveyed to a collecting and filtering device 1 having a pipe connection 13 with the pump. The motor 16 is adapted to slide on rods 17, and, when the vehicle is at rest, drives the pump, a pinion 18 on the motor spindle then gearing with two planet-wheels which are operatively connected with the pump shaft and gear with a fixed internal spur-wheel; or the pump may be operated through a belt or chain. The extracting- tool, Figs. 8 and 9, is supplied with compressed air by a pipe 37, part passing through an adjustable annular opening 41, and the remainder through a nozzle 60 which can rotate in a vertical plane. When the tool is not pressed against the surface to be cleaned, the air supply is cut off automatically by a plug valve 51. The nozzle 60 may be suppressed. The tool is formed in two parts screwed together, so that the area of the annular passage formed between them may be adjusted, and is connected to a delivery pipe 42 by a casting 43, Fig. 11, which permits the tool to turn relatively to the pipe when operated from a spring-controlled catch on the pipe, either through a Bowden wire mechanism, or a rod provided with a rack engaging teeth on the crosshead 47 of the tool. In the collecting and filtering device 1, Fig. 1, enclosed canvas or like tubes 2 with closed upper ends are carried by rods 3 and are attached to a perforated plate 7, the whole being supported over a water chamber 6 connected to a removable dust-collecting box 10 having inlet nozzles 12 provided with tapering slots for discharge outlets. The slot surmounted by the baffle 35 may be closed by a valve or supplied with cleaning-brushes. In a modification, the separate tubes 2 are replaced by a single canvas surface, which is supported so as to form vertical conical tubes. Instead of using a pump 14, compressed air may be supplied from storage tanks carried by the tricycle. A filtering- chamber containing cottonwool backed by canvas, and separated from a dust-box by a wire-gauze partition, may be arranged directly over the extracting-tool. The Provisional Specification mentions the connection by a bayonet joint of the chamber and tool.

Title: Improvements in and relating to Alternating Current Electrical Machinery.
Inventor: THOMPSON WILLIAM PHILLIPS
Filed: 1904-09-05
Granted: 1905-02-09
Abstract: 19,168. Thompson, W. P., [Berliner Maschinenbau Akt.-Ges. vorm. L. Schwarfzkopff]. Sept. 5. Armatures; field magnets.-Relates to the excitation and winding of alternating-current machines, applicable also to transformers, there being an energy-giving winding both on the stator and rotor. Fig. 1 shows a simple arrangement, in which a, b are the magnet bodies, either rotor or stator. On the part a is a three-phase winding 1, 2, 3, and on the part b a corresponding winding 4, 5, 6. An additional winding 7, 8, 9 is provided, displaced half-a-pole from the others. If 7, 8, 9 is an exciting-winding, a rotating field will be produced, and currents of equal frequency will be induced in the other windings, provided the parts a, b are stationary. Should there be a relative movement, the frequency will vary accordingly. When working as a generator, the windings 1, 2, 3 and 4, 5, 6 may be used independently or connected in parallel or series. In the arrangement shown in Fig. 3, two windings are in parallel, and the fields of these windings are stated to destroy one another. In other arrangements, they may be placed in series. The winding 7, 8, 9 may be divided into two parts, one being placed on the part a and the other on the part b. The excitation current may be obtained from a separate source, or the machine may be self-exciting. The machine may be excited by a three-phase winding, and monophase, diphase, or polyphase currents taken from the other windings. The machine may be connected to a circuit carrying wattless currents, to be excited thereby without the provision of separate exciting-windings.
