Patent ES-462130-A1 (ES)
Title: Fluid control valves
IPC: F02M63/00
Filed: 1977-09-05
Abstract: A fluid control valve, principally for controlling the flow of fuel to a compression ignition engine, comprises a valve body and a valve member slidable within the body, the valve member co-operating with a seating on the valve body to control the flow of fluid through the valve. A spring urges the valve member into engagement with the seating and in use, the pressure of the fluid entering the valve is arranged to act on the valve member in opposition to the spring so as to lift the valve member off the seating. The valve member and the seating are formed from electrically conductive material and are electrically insulated from each other except when the valve member is engaged with the seating. An electrical terminal extends to the exterior of the valve body and enables the electrical resistance between the valve member and the seating to be measured. The measured electrical resistance provides an indication of movement of the valve member towards and away from the seating.
Patent ES-465200-A1 (ES)
Title: Tool for removing and installing connector
IPC: H01R43/26
Filed: 1977-12-19
Abstract: The disclosure relates to a tool for installing and removing a housing which is positioned over a row of connector pairs and frictionally engaged with the rows of connector pairs, there being no integral connection between the housing and the contacts. The tool is designed to remove the housing when positioned over the contact members by utilizing a wedge on the tool which separates the contact members so that the housing can be pulled up over the contact members without rubbing thereagainst to remove any plating layers thereon. The housing is installed by the same tool wherein the housing is gripped and, upon insertion of the housing over the contact members, the wedge first spreads the contact members apart and the housing is disposed thereover without rubbing against the contact members. In the case of installation and removal of the housing member, the wedge is designed to push the contacts sufficiently far back so that they do not rest upon a preloading bar disposed within the housing. In this way, the housing can be removed by merely gripping the housing with the tool while the contacts are spread apart and then rocking the housing back and forth so that it can be removed upwardly over the contact members without sliding over the edges of the contact members. The installation would also require a gripping of the housing member but would not require the rocking motion, the housing being installed by a direct downward force thereon.

Title: Recovery of drilling fluids
IPC: E21B21/06
Filed: 1978-02-24
Abstract: Recovery of drilling fluid from the mud leaving the well.

Patent ES-486143-A1 (ES)
Title: Electronic device to supervise the working of a hydraulic servoactuator.
IPC: G09B9/14
Filed: 1979-11-20
Abstract: A hydraulic jack for the controlled displacement of a load, such as a platform used in the training of aircraft pilots, has a servo valve normally settable by an error signal Ve from an actuator including a subtractor followed by an amplifier, the subtractor emitting the error signal as the difference between an externally generated position-control signal Vc and a position-feedback signal Vx sent out by the jack. A monitoring device includes an error detector which generates a safety signal AL disconnecting the servo valve from its actuator whenever the position-feedback signal Vx deviates excessively from a reference signal V'x derived from the position-control signal Vc by means of a simulation circuit whose transfer constant equals, in first approximation, that of the servo system encompassing the jack and the actuator. In addition to several cascaded operational amplifiers, the last of which is an integrator representing an electronic model of the jack, the simulation circuit may include a component responsive to a force-proportional output signal Vp from sensors attached to the jack for limiting the dynamic range of an intermediate signal V's supplied to the integrating operational amplifier, the output signal Vp being also degeneratively fed to the subtractor of the actuator to stabilize the operation of the system.

Title: Circuit arrangement for preventing re-establishment of the starting condition in an electric single-phase motor
IPC: H02P1/44
Filed: 1982-09-23
Abstract: In an electric single-phase motor having a starting circuit, which in connection with an auxiliary winding (2) produces a switching from a starting condition to a running condition when the number of revolutions per minute of the motor during the starting procedure has reached a predetermined value, the starting circuit (5-9) is so designed that after the switching from the starting condition to the running condition it cannot re-establish the starting condition until the feed voltage of the motor has been switched off.

Title: Pruning apparatus
IPC: A01D34/90
Filed: 1985-05-09
Abstract: The invention is directed to a pruning apparatus having a drive motor which is mounted on a carrier adapted for mounting on the back of an operator. The drive motor is connected with a rotating cutting tool by means of a flexible shaft. The flexible shaft includes an output member and a drive member. The output member is connected to a drive motor and is contained in a connecting tube. The output member is connected via a coupling unit to the drive member which is disposed in a guide tube. The guide tube carries the rotating cutting tool which produces a smooth cut so that the formation of fungus at the cut is completely eliminated. A cover plate is affixed to the guide tube so as to be adjacent to the cutting tool and has an outer diameter smaller than the cutting circle defined by the tip of the rotating cutting tool. While operating the apparatus, the stationary cover plate, unlike the rotating cutting tool, remains clearly visible thereby facilitating a precise cutting operation.
