Title: Improvements in or relating to electric induction motors
IPC: H02K17/16
Filed: 1929-05-27
Abstract: 312,914. Swendsen, J. W. June 2, 1928, [Convention date]. Alternating-current induction machines; machines with two or more armatures; cores, yokes, and carcass structures.-An induction motor comprises two or more disc-shaped stators and discshaped rotors the number of which is one more than the number of stators, one rotor being adjacent to each end stator and one between each pair of stators, both stators and rotors being wound from sheet material having slots punched in it so that when the sheet is coiled to give a cylindrical core, the slots register with one another and form ducts for the squirrel cage and stator coils as described in Specification 312,913. One of the stator sections may be displaceable to give the machine a. slip-ring motor starting characteristic. Fig. 1 shows the use of three stators and four rotors, the innermost of which 46, 47 have buried cage bars 41, 42 on both sides connected to outer and inner short-circuiting rings 15, 14, Fig. 2. By using iron strip with copper welded on to its end portions, the core and short-circuiting rings may be coiled in one operation. To impart the starting characteristics of a slip-ring motor to the machine, the central stator may be rotated around the machine axis, for instance by the action of a spring, so that when the motor is stopped the stator turns to a position out of phase with the other stators. The rim of the stator may have teeth engaging a quick-thread screw 44, Fig. 4, this screw having centrifugal or other means for controlling its speed so that the time required for the movable stator to return to its correct phase position as the motor starts up may be adjusted. The Specification as open to inspection under Sect. 91 (3) (a) describes also a two-rotor form, Fig. 1 (Cancelled), having a single fixed stator 1 between the rotors 5, 6. Also a form is described in which the stator core is given an elliptic crosssection, Fig. 2 (Cancelled) by making it from a metal strip the width of which increases from both ends towards the centre, the rotor surfaces in this case being concave. It also states that hand control of the position of one of the stators affords a means for regulating the speed of the motor over a wide range. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to closed feed systems for steam power plants
IPC: F01K9/02
Filed: 1947-06-20
Abstract: 625,226. Feedwater supply systems for steam boilers. WEIR, Ltd., G. & J., and HILLIER, H. June 20, 1947, No. 16308. [Class 123(ii)] A closed feedwater supply system for a steam power plant including a boiler 9 and a turbine (not shown), comprises, in series, a steam condenser 1, a condensate extraction pump 3 discharging through a conduit fitted with valves 4, 15 to a de-aerator 18 with associated de-aerated feed tank 22, and a de-aerator extraction pump 27 in a conduit 28, 29 leading to a boiler feed pump 30 having a disdischarge pipe 31 with valve 32. The condenser 1 and de-aerator 18 are provided with air ejectors 11, 19 and the valves 4, 15 and 32 are controlled by floats 5, 16, 33 respectively. The system additionally includes an external feed tank 8 in communication respectively with the discharge of the pump 3 through a pipe 7 with valve 6, also controlled by the float 5, and the condenser well 2 by a pipe 26 with valve 24 controlled by a second float 23 in the tank 22. The arrangement is such that, when the boiler load is reduced to zero, the water required to maintain the level in the boiler will be drawn from the tank 22, with the result that the valve 24 will open to permit make-up water to flow from the tank 8 to the condenser and thence to the de-aerator 22 to restore the level in the latter. When, however, the load is increased, the surplus water accumulating in the condenser well 2 will effect the opening of the valve 6 and permit surplus water to discharge to the tank 8. A pipe connection 34 with control valve 35 may be provided between the tank 22 and condenser 1 for the circulation of water under light loads to ensure an adequate flow of water through the condensers 10, 16a of the ejectors 11, 19, also a connection 36 with manually-controlled valve 37 between the tank 8 and condenser 1. The valves 15, 24 may be actuated by a single float. In a modification (not shown) the system includes an evaporator which is supplied with sea or fresh water and the vapour from which is condensed and led to the condenser, de-aerator or external feed tank. Two or more of the above systems may be arranged to function in parallel, in which case the external feed tanks 8 are interconnected to maintain a common level; the discharge sides of the pumps 3 may also be interconnected to permit operation with one de-aerator only and, similarly, the pipes between the. pumps 27, 30 are preferably interconnected so that the pumps 27 may deliver to a single feed pump 30. Specification 295,855, [Class 123(ii)], is referred to.

Title: Hydrostatic extrusion system
IPC: B21C23/00
Filed: 1962-05-01
Abstract: 942,642. Extruding. BAROGENICS Inc. May 1, 1962 [May 4, 1961], No. 16667/62. Heading B3P. [Also in Division B5] A billet 45 is extruded through a die 70, 71 on the end of a ram 35 slidable within a cylinder 12 containing the billet, by pressurising an hydrostatic medium 46 surrounding the billet. The ram 35 is integral with or preferably rests upon an hydraulic piston 25 working in a piston housing 16 secured to the cylinder housing 10 by bolts or a bayonet joint or preferably by a split ring clamp 60 and safety ring 61. Outer and inner dies 70, 71 and a die holder 72 with an annular sealing ring 41 are secured by bolts to the top of ram 35; a simple die may be used instead of the dies 70, 71. For cold extrusion, the hydrostatic medium 46 may be water, alcohol or oil introduced through a filler system 53, 55, 56 after insertion of the billet 45. Alternatively the top of cylinder 12 may be closed by a filler plug. For hot extrusion, the medium 46 may be a low melting point metal or glass fibre which becomes fluid at the extrusion pressure and temperature, this medium being inserted when the billet is changed into the cylinder from its lower end after removing the clamp 60. The lower end of the billet is shaped complementary to the entry surface of die 70 to form an initial seal. For extruding the billet hydraulic fluid is admitted through duct 31 whereby piston 25 and ram 35 are moved upwardly to pressurize the medium 46 which thus extrudes the whole of the billet through the orifice in die 71 leading to exit passages 39, 21. Fluid 46 acts as a lubricant during extrusion. In an alternative embodiment, the piston housing 16 and piston 25 are omitted and the cylinder housing 10 with the projecting ram 35 are squeezed between press platens. In a further embodiment, Fig. 3, the cylinder 12 is formed within the piston 25 and the ram 35 is stationary during extrusion. Reference is made to the extrusion of steel, brass, aluminium, plastics and stone.

Abstract: 236,242. Madsenell Corporation, (Assignees of Knauss, F. V.). June 27, 1924, [Convention date]. Void [Published under Sect. 91 of the Act]. Pickling.-Ferrous metal objects such as steel sheets, after treatment by an electrolytic pickling process to remove surface carbon and occluded hydrogen or other gas, are treated with sodium carbonate or other alkaline solution. The alkali is allowed to dry on and is then dissolved off with distilled water, rain water, or water slightly acidulated with hydrochloric or sulphuric acid. It is stated that the alkali treatment causes black or dark blue matter to ooze out from the metal object which is removed in the subsequent rinsing. The treated object may be coated with metal by dipping, spraying, or flowing, or may be coated with paint, vitreous enamel or baking enamel. The preliminary pickling comprises degreasing in hot caustic soda or other alkali, rinsing, and pickling in dilute sulphuric or hydrochloric acid. This is followed by washing, if acid other than sulphuric has been used, and anodic treatment in a bath of strong sulphuric acid, preferably above 84.5 per cent strength. The cathode may be of lead or of iron or steel covered with lead, or of iron or steel. A series resistance about five times that of the cell may be used. The current density is preferably 20 amps per sq. ft. of anode surface, but 5 amps. per sq. ft. or less may be used. The treatment is continued until the current falls to a constant value about one-fifth or less of the initial current. The temperature should be about 100‹ F. Hollow bodies are treated by filling with acid and inserting the cathode therein. The acid need not completely fill the body, provided the body be rotated so that the whole of the interior surface receives treatment. The body should be rinsed after treatment.
