Patent SE-7704071-L (SE)
Inventor: HOFFMAN A H
IPC: H02P1/00
Filed: 1977-04-06
Abstract: Method and apparatus for accelerating a large inertia load from rest to a predetermined speed of rotation by means of a synchronous dynamoelectric machine. A synchronous dynamoelectric machine, such as a turbine generator, which is mechanically coupled to a gas turbine prime mover, is started synchronously to bring the gas turbine up to a speed which exceeds its stall speed under load. The rotor field winding of the synchronous dynamoelectric machine is connected to receive direct current excitation from a rotatable rectifier assembly of a brushless exciter. During starting, a quadrature axis winding disposed around the stator of the brushless exciter is energized by single phase alternating current. Alternating current excitation is induced by transformer action within the rotor armature winding of the exciter and is applied to the rotor field winding after being rectified by the rotatable rectifier assembly. The transformer action operates independently of the rotation of the rotor member of the synchronous dynamoelectric machine so that the brushless exciter develops direct current field excitation for starting purposes when the rotor is at rest. Polyphase alternating current excitation is applied to the synchronous dynamoelectric machine stator winding to establish a dynamic magnetic field which rotates at a speed proportional to the frequency of the applied excitation. Interaction of the static magnetic field of the rotor and the rotating stator field produces the mechanical turning force. The frequency of the synchronously applied stator excitation is increased from substantially zero cycles per second to a higher frequency until the rotor member has accelerated synchronously to the desired speed of rotation.

Abstract: A method for preventing the overcharging of coal into a coke oven system in which preheated coal is transported from a storage container to the coke ovens by means of a substantially enclosed continuous conveyor system filled with inert gas. A portion of inert gas within the enclosed conveyor system is carried along with the coal into the coke oven itself. During filling of the oven, this inert gas is carried up and out of the oven standpipes. When the oven becomes filled, however, the standpipe escape route becomes blocked resulting in a rapid pressure build-up within the system. This rapid pressure build-up is utilized to generate a signal to stop further filling of the oven. The instant method may be employed as a primary regulating system, but is more preferably employed as a back-up to conventional sensor probes used for regulating the level of coal.

Abstract: An improved anchor positioner for use with anchors incorporated in a liner or casing of a well bore. The anchor positioner comprises upward-facing spring arms having downward facing shoulders on the exterior thereof, the spring arms, when extended radially outward, engaging a shoulder on an anchor to locate a tool string in a well bore. An indexing head, rotatable in response to axial reciprocation of the tool string, retracts the spring arms from the anchor. A subsequent reciprocation of the tool string will cause the spring arms to extend radially outward and to be locked in the extended position by contact with the indexing head, thus locking them into the anchor against downward movement. Retraction of the spring arms is effected by force from contact with inwardly-inclined faces on the indexing head, and extension of the spring arms is effected by outward force exerted by contact of the inside of the spring arms with axial grooves on the outside of the indexing head. Rotation of the indexing head and therefore change of radial alignment is effected through a pin and slot mechanism.

Abstract: The present invention concerns an arrangement in a mill for disintegration and/or mixing of materials such as dirt, bark, etc. In the mill, the material being disintegrated drops down under force of gravity from an inlet opening 4 at the top of the mill through a shaft 1 in the mill toward an outlet opening 5 at the bottom thereof. In this process, the material passes through disintegrating elements arranged in the shaft 1. These comprise at least one motor-driven horizontal axle 8, pivoted in two opposite walls of the shaft, having beaters 9 evenly distributed along its length and hinged in the plane of rotation of the axle, which upon rotation of the axle 8 strive to take up a radial position, and counterbeaters 10 arranged stationary and mutually parallel in a shaft wall 2 lying between said shaft walls and being yielding in the direction of beating, which stretch forth in between the aforesaid beaters 9 approximately across the direction of flow of the material through the shaft. The invention is characterised in that the arrangement contains sealing elements arranged on either side of the inlet opening 4, which extend between said opposite shaft walls and from the inlet opening 4 toward the rotating beaters 9. <IMAGE>

Abstract: A method is disclosed for improving the performance of noble metal catalysts such as platinum in catalyzed chemical reactions where the reduction of oxygen is a rate limiting step. The catalytic activity of the catalyst and thus, the rate of reaction is increased by increasing the electron density of state at the Fermi level of the catalyst. This can be accomplished, for example, by alloying the noble metal catalyst with materials which increase the electron density of state; i.e. by solid solution alloying. Among the elements which may be used are W,V,Mo,Co and Cr.

In a second step flue gas is recycled to the combustion-air inlet (7, 25) beneath the grate in an amount such that the surface temperature of the bed will not substantially exceed 1100 DEG C, resulting in the binding of sulphur by the formation of calcium sulphate, and low nitrogen oxide emission.
