Patent ES-376976-A1 (ES)
Title: Direct current motor circuits
IPC: H02P7/28
Filed: 1970-02-27
Abstract: The shunt field winding 17 of a D.C. motor 14 is energized with pulses of current from a D.C. source 10 by a conventional arrangement of thyristor 20 and commutating circuit 21...24, the thyristors 20, 21 being alternately triggered from respective trigger circuits 28, 27 which are controlled by an astable multivibrator 26 whose output to the circuit 27 is fed through a network including a transductor 31 arranged to inhibit operation of the trigger circuit 27 when its core is saturated. The transductor carries a winding 13 responsive to the armature current of the motor, a winding 18 responsive to its field current and a winding 30 controlling the circuit 27, the flux in the transductor core being produced by an adjustable magnet 32 whose effect is augmented by the winding 13 and opposed by the winding 18. The motor drives a vehicle whose accelerator pedal 33 controls the magnet 32 so that the position of the latter determines the power developed by the motor. With the magnet 32 in a position producing maximum flux, the firing of thyristor 21 is inhibited until the field and magnet fluxes balance to produce a "standing field current" whose value is determined by the permanent magnet. Movement of the latter to reduce the transductor flux below the saturation level, produces a reduction of the field current until a predetermined weak value is reached corresponding to the magnet fully out and no inhibition of the circuit 27. Thereafter the field current is controlled by variation of the armature current, the arrangement being such that the field current increases with armature current after the latter has reached a predetermined value (determined by providing non- magnetic members in the transductor core). If the armature current is sufficiently high, inhibition of the circuit 27 occurs to produce a condition of maximum field current. During acceleration of the motor an appropriate proportion of trigger pulses from circuit 27 are inhibited until maximum speed is reached and the armature current falls to a level sufficient to allow normal triggering of thyristor 21 and return of the field current to the aforementioned weak value. When the vehicle encounters a gradient at full motor speed, the armature current increases to increase the inhibition of the circuit 27 and the value of field current as before. The "standing field current" condition determines the field current during rheostatic and regenerative braking. For the latter, the flux produced by the armature current is reversed to oppose that of the magnet and so reduce the field current as the regenerated armature current increases. For the former, no armature current flows and no flux is produced in the transductor core by the winding 13. The armature control circuit 15 may comprise conventional contactors and starting resistors.

Title: Light fixture
IPC: F21V19/04
Filed: 1970-04-04
Abstract: A light fixture comprising a housing having an opening intermediate oppositely facing walls to permit a lamp to be moved into and out of the interior of the housing. A closure is removably disposable across the opening to enclose the housing in weather-tight fashion. A sleeve on one of the oppositely facing walls of the housing receives an electrical socket for axial movement between retracted and extended positions. A means on the other of the oppositely facing walls provides a face of heat insulating and cushioning material for engaging the non-electrical end of the lamp when the electrical end thereof is received within the socket. The face and sleeve are spaced apart a distance which permits the electrical end of the lamp to be moved into and out of the socket when the socket is retracted. A means is provided for positioning the socket in its extended position so as to hold the opposite, non-electrical end of the lamp against the face of heat insulating and cushioning material.

Title: Method and apparatus for the removal of sand bales containing castings from molding boxes of poured foundry molds
IPC: B22D29/04
Filed: 1978-12-26
Abstract: Sand bales containing castings are removed from poured foundry molds by clamping together in a horizontal position the molding boxes containing the sand bales, by supporting the sand bales from below independently of the molding boxes, and by applying to the molding boxes jarring or accelerative forces acting in a vertical direction with a magnitude exceeding the static frictional forces which exist between the sand bales and the molding boxes, with these forces being applied while the sand bales are supported thereby to cause the sand bales to move out of the molding boxes. In one aspect, the sand bales are supported from below by a force lower than the weight of the bales thereby to permit the bales to drop out of the molding boxes while the accelerative forces are applied to the molding boxes in an upward direction. Conversely, the sand bales may be lifted upwardly out of the molding boxes with accelerative forces being applied to the molding boxes in a downward direction.

Title: Top nozzle for a nuclear reactor fuel assembly
IPC: G21C3/33
Filed: 1979-06-13
Abstract: A top nozzle for a nuclear reactor fuel assembly which includes an orifice plate designed to receive control rod guide tubes extending upwardly from the top of the fuel assembly. Nozzle pin extensions connected to the orifice plate are axially coextensive with the guide tubes and project upwardly through a top nozzle hold-down plate, and through openings in the upper core plate in the reactor. The hold-down plate is spring biased into an upper core plate engaging position and since the pin extensions are adapted to move in the core plate and against the action of the springs, the top nozzle thus becomes effective in accommodating upwardly acting hydraulic forces which tend to lift the fuel assembly, and to accommodate differential expansion of parts in the fuel assembly as compared to the core barrel in which the assembly is located. The number of pins disposed in the hold-down plate move in slots formed in each of the guide tube extensions and the uppermost position of the fuel assembly is determined when the pin is in the bottom of its slot in each of the guide tubes.
