Abstract: 859,066. Making dynamo-electric machines. IMMOVILLI, S. Oct. 9, 1958, No. 32207/58. Class 83 (2). [Also in Group XXXV] A process for fabricating dynamo-electric machine stators comprises, Fig. 5, applying an adhesive layer 60, e.g. a synthetic resin to the cylindrical outer surface of a laminated stator core 2 having annularly arranged teeth between which windings 4 are carried, placing a cylindrical yoke 1 radially outside the core outer surface, and applying radially outward pressure to the core to bond it by the adhesive to the yoke.

Abstract: 940,045. Controlling burners. NU-WAY PLANTS Ltd. Aug. 23, 1962 [Sept. 8, 1961], No. 32280/61. Heading F4T. In a liquid fuel burner control apparatus having a piston 6 of a fuel valve 1 adapted to close a fuel outlet 4 leading to a burner and an abutment 9a axially adjustable to compress a coil spring 8 acting on the piston, the abutment 9a is connected to an air valve 13 whereupon adjustment to the spring pressure automatically adjusts the combustion air supply. The fuel is delivered to an inlet 2 by a pump 3 and the fuel pressure opens the valve, excess pressure being released by co-operating ways in the piston and valve, when the piston has moved a predetermined distance. The abutment 9a screwthreadedly engages the valve body and has a rotatably mounted arm 11. The latter is connected to a slide 12 which increases the opening of an air valve 13 when the abutment is rotated to increase the fuel supply. In a modification, the abutment 9a engages the valve body with a fine thread and engages the arm 11 with a relatively coarse thread so that when the abutment is rotated to increase the fuel supply to the burner the slide 12 moves in the opposite direction to the abutment to open the air valve. In a further modification, Fig. 2 (not shown), a plunger replaces the screw and is operated by a motor controlled automatically by the temperature and/or humidity in the apparatus heated by the burner. In a final modification, Fig. 3 (not shown), the fuel and air valves are controlled by a temperature-responsive power unit immersed in a liquid heated by the burner.

Abstract: 992,703. Fluid-pressure brakes. WAGNER ELECTRIC CORPORATION. Sept. 8, 1961 [Nov. 29, 1960], No. 32289/61. Headings F2E and F2F. A fluid-pressure system comprises a fluidcooled retarder brake adapted to be actuated in direct response to pressure fluid metered thereto from a pressure fluid source, service brakes and a control valve having an inlet connected to the source and an outlet connected to the service brakes. The control valve is subjected to the pressure fluid metered to the retarder brake and is responsive only above a predetermined fluid pressure actuating the retarder brake for developing a fluid pressure in the service brakes. As described a first valve meters fluid from a compressor and a reservoir to the retarding brakes, e.g. fluid-cooled disc brakes. The control valve 11 acts to supply fluid from the reservoir to service brakes and has a control port 47 connected to the outlet side of the first valve and inlet and outlet ports 34, 35, connected respectively to the reservoir and the service brake actuating cylinders. When the metered fluid pressure from the first valve acting on the diaphragm 23 exceeds the combined upward force of atmospheric pressure acting on the diaphragm 26 and the compressive force of the spring 48 the valve stem 42 moves downwardly to close the vent bore 41 and open the valve 38 to allow fluid to pass from the reservoir to the service brakes. A valve is provided in the system which may be moved so that the two sets of brakes are simultaneously energized in response to actuation of the first valve, the control valve being vented to atmosphere. Specification 992,704 is referred to.

[Classes 78 (i), 78 (iv), and 78 (v).] In loading-apparatus comprising a scraper hauled to and fro between the working face and a truck loader, the scraper haulage gear is carried on a truck loader of the continuous conveyer type. As shown, the coal from the soraper is delivered by a shoot 53 to the receiving end 10 of the scraper conveyer 13 of the loader, and the loader delivers at 11 into a truck. The scraper haulage gear, mounted on the undercarriage 14 beneath the conveyer, comprises a motor 19 geared at 33 to a shaft on which are loosely mounted the two drums for the head and tail ropes. The drums are driven through epicyclic gearing, one of the planet carriers being held fast as required by operating the brake levers 27, 28 for transmitting the drive to the outer member of the gear and to the drum. Preferably, the drums are kept within the width of the loader. The haulage ropes are led around sheaves at 23 and to head and tail sheaves at the ends of the working face. The loader conveyer 13 may be driven from the haulage motor 19 through the sprocket 23 on the shaft of the haulage drum, a sprocket 35 and epicyclic gearing. The planet member of the epicyclic gear is locked by a brake 39 operated from the point 41, in order to transmit the drive to the outer member of the gear which drives the conveyer through sprocket 38, 45. The scraper may deliver to the truck loader over a bridge. The conveyer may be driven by a separate motor, and the loader may be propelled by the motor or motors of the scraper haulage and conveyer gear.

Abstract: 961,180. Commutation arrangements for dynamo - electric machines. FABRIQUES MOVADO. Sept. 26, 1960 [Sept. 30, 1959], No. 32949/60. Heading H2A. A rotating magnetic field for a motor is obtained by supplying each stator field winding from an inductively coupled transistor oscillator and causing the oscillators to operate in sequence by means of a sensing device attached to the rotor. A notched screen E (Fig. 9) of electrically conducting material rotates between the coupling coils O1, 02 of the oscillators and thereby prevents them from oscillating except when the notch lies between the coils. In a practical case the stator may consist of three salient poles each wound with two coils so that each oscillator supplies coils on two adjacent poles in series M1, M2, M3 and when the rotor rotates, the notch L in screen E co-operates with the coupling coils in turn to energize the stator windings and produce a rotating magnetic field. In a second modification (Figs. 10, 11, 12, not shown), the rotor may have equi-spaoed pole teeth and the stator comprise an arcuate member, having poles with the same pitch as that of the rotor poles, which is excited periodically to give an accelerating torque to the rotor. Various oscillator circuits are shown and it is also disclosed that the screen might vary the coupling in a capacity coupled oscillator to control the output, Fig. 7 (not shown). The rotating disc may be partially made of magnetic material which may be magnetized.
