Patent ES-434288-A1 (ES)
Title: Dual mode deflection synchronizing system
IPC: H04N5/08
Filed: 1975-01-30
Abstract: A dual mode deflection synchronizing system includes a resettable counter which generates noise-free internal synchronizing signals and signals representative of the interval during which external vertical synchronizing signals should be received provided the counter is properly synchronized. A sync signal verification detector is coupled to the source of external vertical sync signals and to a mode switch so that if the external signals arrive during this prediction interval as determined by the sync signal verification detector the system continues to operate in a synchronized mode on its internally generated synchronizing signals. If the external signals do not arrive during this prediction interval, the mode switch switches the system into a non-synchronized mode. A vertical sync signal detector which is also coupled to the source of external sync signals and to the mode switch begins to search for an external signal which has the time duration characteristic of an authentic external synchronizing signal. Until such a signal is received, the system continues to be synchronized by internal synchronizing signals generated by the resettable counter. When such a signal is received, the vertical sync signal detector resets the counter to correct its synchronization with the received external vertical synchronizing signal and toggles the mode switch to return the system to its synchronized mode of operation.

Title: Fluid circuit or logic element
IPC: F15C3/00
Filed: 1978-06-21
Abstract: An annular chamber in a housing has inlets at both ends. A central segment of the changer has on its inside wall a groove tapering toward the inside and leading at its base to a centrally located output passageway.

Title: Hydraulic force resister
IPC: A63B21/008
Filed: 1978-06-21
Abstract: A push-pull isokinetic exerciser composed of inner and outer telescoping tubes whose ends have handle pieces attached thereto. The inner tube defines an oil-filled chamber which encloses a piston whose actuating rod is attached to the handle end of the outer tube. The piston divides the chamber into right and left sections provided with valves that function alternately to allow oil to pass from the right section to the left section when the tubes are brought together by the handle pieces in a compression stroke, and that allow oil to pass from the left section to the right section when the tubes are pulled apart in an expansion stroke. The motion in the compression and expansion strokes is linear and affords uniform resistance to motion throughout the entire length of each stroke, so that the exercising effect is even and free of strain. Each handle piece is constituted by a cap which covers and protects the end of the tube to which it is attached, a U-shaped yoke secured to the base of the cap and having arms projecting therefrom and a handle bridging the arms, the handle having a longitudinal bore therein to receive the mid-section of a crossbar, whereby the user may engage the handle piece with either hand or foot, or may engage the ends of the crossbar protruding from the handle with both hands or both feet.

Patent ES-477796-A1 (ES)
Title: Overload protection circuit for video amplifiers
IPC: H04N5/14
Filed: 1979-02-16
Abstract: To avoid excessive dissipation in a video output stage, particularly in Class B or C operation, signal transfer of higher frequencies, e.g. noise, is selectively attenuated. Accordingly transferred signals, e.g. en route to the output stage, are sampled 17, 15, differentiated 53, clamped 56, rectified 55 and then integrated 57 to switch on a normally off transistor 52 whenever high frequency signals are incident. Since the integrator 57 has a bleeder shunt 58, only high density high frequency signals will switch on the alarm transistor 52. If these occur, the video signal transfer is progressively reduced, e.g. by conditioning the output 62 of the luminance contrast control 60, whereof a resistance 65 may pass the collector current of the alarm transistor 52.
