Patent ES-433733-A1 (ES)
Title: High intensity lamp dimming circuit
IPC: H05B41/40
Filed: 1975-01-11
Abstract: A high intensity lamp dimming circuit in which the lamp or lamps are placed in series with a pair of reactive elements, one of which is at least partially bypassed when the voltage across the element and the current through it are of the same polarity. The relative time of the bypass determines the amplitude of the lamp current and hence its brightness. A control network, isolated from the power lines to which the lamp network is connected, controls the timing of the bypass. This control network preferably uses a programmable unijunction transistor and operates on a low-level dc setting. The control circuit design permits ready connection to single phase and three phase power systems alike.

Title: Laying of submarine pipes
IPC: F16L1/16
Filed: 1976-03-26
Abstract: The invention relates to a method of laying submarine pipelines by submergence from the surface or from an adjacent level with one point of the pipeline being secured near to the surface so that the pipeline on being submerged comprises a section descending from this point towards the bed and connected by a curved section to the part of the pipeline already laid on the bed, in which weights are suspended from the pipeline at intervals thereon, at least at the time of its submergence, such that the assembly has a slightly negative buoyancy and the pipeline sinks slowly in the water until it is slowed down and stopped when the weights contact the bed, the weights thus acting as a guide rope. The invention is applicable both to the case in which the sections of the pipeline are assembled on a floating device and the pipeline is lowered into the water as assembly proceeds while the floating device is moved along the laying course, and to the case in which the pipeline, previously constructed by the assembly of a certain number of sections, is towed along the laying course and is associated with floats which maintain the pipeline on the surface of the water or a short distance therebeneath and which can be put out of action to allow the pipeline to sink.

Title: Cooling system for a vehicle clutch
IPC: F16D13/48
Filed: 1976-11-09
Abstract: A cooling system for a vehicle clutch including a cooling fluid distribution means and a heat exchange means. A bell housing encloses the clutch assembly and provides a sump for containing cooling fluid. A clutch pressure plate has a plurality of pickup tubes formed on its periphery which are passed through the cooling fluid as the pressure plate rotates with the engine flywheel.

The inlet openings of adjacent pickup tubes are offset with respect to one another to increase the flow of cooling fluid. The rotation of the flywheel and the pressure plate generates a flow of the cooling fluid in the pool. A sump pan is connected to the bell housing and includes a baffle for diverting the flow of cooling fluid into the sump pan which is formed with a corrugated bottom and finned sides to function as a heat exchange means.

Patent ES-470453-A1 (ES)
Title: Speed setting and control system for universal motors
IPC: H02P7/295
Filed: 1978-06-02
Abstract: A universal motor is energized by a speed setting circuit during one half wave and a speed control circuit during the next half wave of each cycle of an AC supply. The speed setting and speed control circuits each have a separate timing circuit including a capacitor. There is thus no residual charge on the capacitor of the speed setting circuit remaining from the operation of the speed control circuit during the preceding half wave. The residual charge prevented the setting of low motor speeds in the known systems. The speed control circuit includes a storage capacitor transformer coupled to the motor so that its initial charge corresponds to the current through the motor during the preceding half wave. The charge is transferred to a second capacitor. When the voltage across the second capacitor reaches a predetermined threshold valve, a switch in the speed control circuit becomes conductive and current flows through the motor.
