Patent ES-8201373-A1 (ES)
Title: Motor control apparatus and method
IPC: H02P7/28
Filed: 1980-10-17
Abstract: A direct current motor controlling apparatus determines the operational speed of one or more direct current motors such as traction motors propelling a passenger vehicle along a track. The speed of the motor is established by changing the on and off conduction ratio or duty-cycle relationship of a switch device to determine the field current and the armature voltage of that motor. The present apparatus utilizes solid-state switch devices to determine the mode of operation of the motor control apparatus which solid-state switch devices are more reliable and more simple in operation and less expensive to maintain.

Title: Nuclear reactor.
IPC: G21C5/06
Filed: 1984-12-18
Abstract: A nuclear reactor in which the bottom nozzle of each fuel assembly is a casting having leg-like pins which are cast as part of the bottom nozzle. The pins extend from the corners of the bottom nozzle of each fuel assembly. The transverse cross section of each pin has the shape of a circular sector whose arc depends on the number of apeces of the bottom nozzle, typically 90 DEG for a square nozzle and 120 DEG for a hexagonal nozzle. The fuel assemblies are mutually nested side-by-side so that a group of contiguous pins extends from each region where corners of fuel elements converge. The sides of the pins of each group are in engagement so that the pins of the group form a continuous circularly cylindrical surface. The core support plate has a plurality of holes. The boundaries of the holes are circular cylinders. Each group of pins extend into a hole in the core support plate. The holes and the pins are so dimensioned that the cylindrical body formed by each group of pins is a snug sliding fit in the corresponding hole. The fuel assemblies are thus effectively positioned, supported and aligned.
