Title: Flow measuring device for a fluid.
IPC: G01F1/06
Filed: 1983-11-25
Abstract: The device measures the flow of a fluid and comprises a rotor 16 having vanes which is driven in rotation by a stream of fluid in a sealed housing 11 having a circular cross-section and provided with a supply nozzle and a discharge nozzle for the fluid which are in alignment and disposed tangentially to the rotor so that the fluid stream issuing from the supply nozzle encounters the vanes 1 in a direction perpendicular to the axis of rotation 17 of the rotor. The rotor 16 has two lateral flanges 16a, the vanes, the flanges and the housing defining, apart from a clearance for permitting the rotation of the rotor, a series of compartments which communicate by way of that clearance with two lateral chambers 12a of the housing.

Patent ES-8501832-A1 (ES)
Title: Door lock assembly.
IPC: E05B63/20
Filed: 1983-12-29
Abstract: A door lock assembly (4) for fitting in a door (6) in the usual way having a deadbolt subassembly (12) with a deadbolt (42) shiftable between an extended locked position and a retracted unlocked position by an actuator arm 66 and biased toward the locked position by a spring (54). The deadbolt is restrained in the retracted position by restraining plates (28, 34) which release the deadbolt via a trigger subassembly (16). Such a deadbolt is thus automatically mechanically actuated with door closure for security so that closing the door actuates the trigger mechanism releasing the deadbolt restraining means and allowing the biased deadbolt to be thrown to the extended locked position.
Patent ES-8501155-A1 (ES)
Title: Compact cassette tape player with capstan drive motor under spindle
IPC: G11B15/26
Filed: 1984-02-09
Abstract: A compact cassette tape player has a motor drive system which enables a high-fidelity tape player to be made only slightly larger than the cassette being played. The tape player includes a motor which has a flat stator mounted to the player chassis, a motor shaft and a flat motor which is mounted to the motor shaft for rotation relative to the stator. The recorder includes reel pawl hubs or spindles for engaging the tape reels in the cassette. The motor shaft extends into one of the pawl hubs and is mounted in bearings at the ends of the shaft. One of the bearings is located inside the pawl hub so that the bearing mountings for the motor shaft can be spaced as far apart as possible, thus reducing the amount of wow and flutter even though the player is extremely compact. The pawl hub mounting the motor shaft is driven independently of the motor by a drive gear which engages the periphery of a gear wheel secured to the pawl hub. The drive gear is driven by a drive belt which extends from the motor rotor to the player capstan.

Patent ES-8701352-A1 (ES)
Title: Process for the cleaning flow-restricted areas of the secondary side of a steam generator.
IPC: F22B37/48
Filed: 1985-03-15
Abstract: A process for cleaning out deposits collected in the restricted areas of the secondary side of a steam generator of a nuclear power plant system, where the concentration of an aqueous organic cleaning agent solution is increased in the restricted areas, relative to the remainder of the solution. The solution is heated, at an initial pressure which prevents boiling of the solution, and the pressure is reduced to effect localized flashing and boiling of the solution in the restricted areas. After a period of time, the pressure is increased and the cleaning agent solution, containing solubilized deposits, is withdrawn from the secondary side of the steam generator. The heating temperature and pressure will vary depending upon the type of deposit to be removed, either ferrous-type or copper-type deposits.

Patent ES-8607794-A1 (ES)
Title: Control system for manipulator apparatus with resolved compliant motion control.
IPC: B25J9/18
Filed: 1985-05-31
Abstract: A control system for manipulator apparatus having a manipulator arm movable in a plurality of axes utilizes resolved compliant motion control to improve servo response characteristics. The position and velocity of the manipulator arm are controlled using load modeling to account for compliance in the arm and to synthesize feedback signals representing movement of a remote point of the arm to provide a loop bandwidth greater than is possible using feedback signals from inner less remote points of the manipulator that are closer to the drive points. The feedback signals are derived using predetermined combinations of force related feedback signals from the axis drive arrangements and position and velocity feedback signals of the manipulator apparatus at points closer to the main drive and support structure of the manipulator and before certain compliant portions of the manipulator arm. To further enhance response and control of the manipulator arm, load modeling is also used to provide controlled deceleration before the manipulator arm is brought to a stop during work operation.
Patent ES-8702617-A1 (ES)
Title: Priority valve
IPC: F15B13/02
Filed: 1985-06-14
Abstract: A priority valve is disclosed for controlling fluid flow between a power source and a secondary hydraulic function operated by the power source. The priority valve includes a housing having first and second bores formed therein. An inlet passage connects the power source to the first bore while an outlet passage connects the first bore to the hydraulic function. A priority function is also fluidly connected to the power source upstream of the priority valve. A valve spool is positioned in the first bore. The valve spool is movable between a first position blocking fluid flow from the first passage to the outlet passage and a second position permitting fluid flow therebetween. A pin is movably positioned in the second bore and has an enlarged end which extends into the first bore. Springs are present for urging the valve spool toward the first position and the pin toward the spool valve. A load signal passage connecting the priority function to the second end of the first bore. When full fluid is demanded by the priority function the valve spool moves toward its first position. When the priority valve demands less than full flow the spool valve moves toward its second position. If the priority function demands pressure approaching a maximum pressure which can be delivered by the power source the enlarged end of the pin contacts the valve spool and forces it toward its second position.
