Patent ES-453032-A1 (ES)
Title: Liquid level gauge
IPC: G01F23/26
Filed: 1976-11-05
Abstract: A gauge for monitoring the height of liquid contained in a storage tank or the like, comprising a channel-like structure having a first elongate probe element constituted as a circuit board having a conductive strip running for a substantial length therealong, an additional upright probe element also constituted as a circuit board, coextensive with the first and also having a conductive strip running for a substantial length therealong, and an elongate member disposed along the boards and constituting a spacer for maintaining the conductive strips of each of the elements in substantially parallel relation. Means are provided for mechanically connecting the boards to the spacer, with both probe elements being adapted for immersion in the liquid being gauged. In addition, means are provided for impressing a voltage on the conductive strip of one probe element, and additional means for detecting voltage induced or sensed on the conductive strip of the other probe element, the latter voltage being a function of the immersion of the elements in the liquid being gauged. By the invention there is no dielectric material in the area between the conductive strips. Accordingly, the likelihood of debris and residue in the tank bridging the gap between the strips is greatly minimized, since there is complete access of the fluid to those portions of each board which carry the strips. Improved performance and accuracy over extended periods of use thereby result.

Title: Device for anchoring fixing means in a concrete element
IPC: E04B1/58
Filed: 1977-03-09
Abstract: The device comprises, for anchoring each T-shaped fixing bolt in a concrete element, a passageway opening onto an outer face of the element and extended by a cavity which allows rotation of the head of the bolt through 90 DEG . A longitudinal reinforcement which is parallel to the outer face is located at a short distance from the outer face and near to the inner end of the passageways. The reinforcement has in the region of each passageway an opening for the passage of the head of the fixing bolt when this head extends in a direction parallel to the longitudinal axis of the reinforcement. Two retaining surfaces adjoining the opening retain the head of the bolt when it is perpendicular to the longitudinal axis of the reinforcement. Arch-shaped members are fixed to the surface of the reinforcement which is adjacent the outer face of the concrete element and have inclined branches which extend into the concrete in a direction opposed to the outer face to a sufficient depth to distribute the forces within the concrete element.

Patent ES-462469-A1 (ES)
Title: Control device for a hydraulic motor
IPC: F15B11/02
Filed: 1977-09-20
Abstract: The invention relates to a hydraulic motor assembly which includes a hydraulic servomotor operable in either direction with a control valve. When the motor is operated in a selected direction, as distinguished from the return direction, it is desired that external forces acting on linkage connected to the piston of the hydraulic motor do not alter the speed of the piston. The control valve has two operating positions and two sets of supply and return passages which facilitate operation of the servomotor in either direction. A brake valve between one of the servomotor ports and the control valve has a scanning port which scans or senses the downstream pressure of either of the control valve supply passages, depending on the control position of the control valve. When the servomotor is operated in the selected direction and an external force as referred to above is encountered, the brake valve operates in response to an increased pressure in the return line and a decreased pressure in the supply line, sensed through the scanning port thereof, to throttle the flow of return fluid in the return line to thereby dampen the tendency of the servomotor to accelerate responsive to the externally applied force. In addition to this function the brake valve is also arranged to allow the return line to be pressurized with supply fluid to effect movement of the servomotor in the return direction.

Title: Voltage regulator for a television deflection circuit
IPC: H04N3/185
Filed: 1977-11-23
Abstract: A feedback voltage regulator for a television deflection apparatus having a deflection switching arrangement driving a deflection winding and supplied with power from a source of potential through a first inductor includes a second inductor coupled in series with the first. The second inductor conducts a substantially direct current towards the source of potential. An SCR is coupled in parallel with the second inductor and its conduction is duration modulated in response to the regulated voltage. The duration modulation controls the time during which the direct current is withdrawn from the deflection switching arrangement and first inductor and thereby maintains the regulated voltage substantially constant.
