Patent ES-452840-A1 (ES)
Title: Digital demodulator for differentially encoded phase-shift-keyed data
IPC: H04L27/18
Filed: 1976-10-29
Abstract: A demodulator for differentially coherent phase-shift keyed data signals correlates samples taken in consecutive baud intervals. Depending on the results of at least two such correlations or lack thereof, counts are registered in unidirectional counters supplied with thresholds related to preassigned counts per baud interval. Bistable circuits respond to the attainment, or failure of attainment, of the threshold-count levels during each baud interval, after which the counters are reset to a reference level. The states of the bistable circuits directly represent binary data without further logic operations in the four-phase case particularly.

Title: Method and apparatus for aligning a valve head
IPC: B21D3/16
Filed: 1976-11-13
Abstract: A method and apparatus for aligning the head of an engine valve in relation to the valve stem. A pair of die members is provided, the first die member being fixed relative to the frame of the apparatus and the second die member being cylindrical and rotatably mounted relative to the first die member. Each of the die members includes a surface for engaging the stem of the valve to straighten the valve stem as it is rolled between the surfaces in a generally arcuate path. A head straightening assembly is disposed adjacent the die members, including a straightening wheel freely rotatable relative to the die members. The straightening wheel includes a straightening surface which rollingly engages the surface of the valve head as the valve stem is rolled between the die surfaces in the arcuate path. The straightening surface is permitted to move at a surface speed approximately the same as the surface speed of the valve head, thus eliminating rubbing action between the valve head and the straightening surface, as well as any substantial torsional force on the valve stem.

Title: Stabilized automatic brightness control network in a video signal processing system including an automatic kinescope beam current limiter
IPC: H04N5/57
Filed: 1980-03-25
Abstract: A video signal processing system is disclosed including a sample and hold comparator arranged in a closed control loop with a video channel including a video amplifier for the purpose of providing automatic brightness control, and an automatic kinescope beam current limiter. The beam current limiter is coupled to a first point in the amplifier for controlling the amplifier signal gain to limit excessive beam current demand in a first control mode. In a second control mode, the beam current limiter cooperates with the automatic brightness control network to control the D.C. output level of the video amplifier in the presence of excessive beam current demand. The comparator response time is slow relative to transient variations of the D.C. level at the amplifier output induced by beam limiter action in the first control mode, but is otherwise sufficient to permit compensation of relatively long term variations in the output D.C. level. Compensation of the transient D.C. variations is provided by coupling transient beam limiter control voltages developed in the first control mode to a second point in the amplifier, for opposing transient D.C. level variations which would otherwise appear at the amplifier output in response to beam limiter action.

Title: Winding method for an electrical generator and generator manufactured by the method
IPC: H02K3/28
Filed: 1980-05-23
Abstract: A three-phase stator winding of an alternator is divided into six partial windings. Each partial winding, regardless of electrical phase, is wound starting at the slot immediately adjacent to the slot wherein the last previously wound winding was started and in the same winding direction. The first partial windings for the subsequent phases are also inserted in the slots in the same direction as the first partial winding for the first phase, so that connecting arcs are formed on the same side of the stator as was the case for the first phase. The second partial windings for each phase are placed so that the connecting arcs form on the side of the stator opposite to that on which the first connecting arcs were formed. The winding starts and winding ends of each of the partial windings associated with a given phase are connected so that the partial windings are connected either in series or in parallel. The so-formed series or parallel circuits are then connected to form either a Y or a DELTA configuration.
