Patent ES-466221-A1 (ES)
Title: Low pressure drop girth baffle steam separator
IPC: B01D45/16
Filed: 1978-01-20
Abstract: A separator for separating water from a mixture of water and steam in which an elongated, outer, water scroll is concentrically spaced from an elongated, inner, steam scroll. One longitudinal edge of each scroll is connected to a girth baffle disposed adjacent the side of a steam drum, and both scrolls extend through semi-circular curves of 180 DEG in cross section. The steam scroll is covered through the first 90 DEG of its curve, and is provided with a longitudinally-elongated opening extending circumferentially the second 90 DEG of its curve. A perforated plate encloses the bottom of the steam scroll to form a longitudinal flow passage. The centrifugal action imparted by the 180 DEG curvature of the separator causes the water to sepate from the steam-water mixture introduced between the steam and water scrolls, to flow along the inner surface of the water scroll, and to discharge downwardly through perforated, water splash diffuser plates. The steam passes through the elongated opening in the steam scroll and through the longitudinal flow passage to discharge from the separator at both ends.

Title: Apparatus for removing appendages from avian species by using electrodes to induce a current through the appendage
IPC: A01K45/00
Filed: 1979-01-11
Abstract: A method and apparatus for removing appendage tissue from avian species such as domestic fowl and principally from commercial chickens and turkeys is disclosed. When the appendage is the beak, the method is known as debeaking and the invention is a method comprised of the step of burning and simultaneously cauterizing a hole through a portion of a bird's beak in order to damage the tissue and precipitate eventual rejection thereof outwardly from the point of damage, and apparatus which includes means adapted to position the bird's beak between and in contact with opposing electrodes projecting into the apparatus which effect the burning as aforesaid. A power source for the electrodes providing an open circuit voltage of sufficient magnitude to initiate current flow through the beak when opposing sides of the beak contact the electrodes. With current flow initiated, the power souce current increases toward a maximum short circuit value sufficient to cause burning of the portion of the beak between the electrodes, while the voltage drops to a value sufficient to maintain the desired current. The preferred control for the power source determines a time integral of current flowing through the bird's beak and, upon reaching a predetermined time integral of current value, the control de-energizes the power source.

Title: Automatic lock-positioning of foldable helicopter blades.
IPC: B64C27/54
Filed: 1981-10-09
Abstract: The foldable rotor blades (12) of a helicopter are automatically adjusted to pitch angles where they can be locked as a prerequisite to folding, by commands generated to cause trim actuators (39-41) to drive swash plate servos (17-19) to the correct positions, initially in response to stored trim references and eventually in response to the difference between stored swash plate servo positions and current servo positions (20-22). One embodiment uses values of servo positions (20-22), just before unlocking the blades upon re- spreading them, to store, in nonvolatile memory, deviations from nominal positions stored in read only memory, and generates trim references in a subsequent folding operation in response to integrated values to reduce actual position errors toward zero from desired positions indicated by the stored deviations.

Patent ES-8504520-A1 (ES)
Title: Laser-beamwelding.
IPC: B23K26/14
Filed: 1984-04-18
Abstract: Contiguous metal plates are welded together without special edge preparation or bevelling e.g. of cut edges 13 from one side using a focussed high intensity laser beam 7. To ensure maintenance of welding conditions even when the plate edges are spaced apart by cutting imperfections or the like a wire 12 is fed to, or near, the beam focus 10 to intercept the beam and give rise to a plasma. This plasma is kept in place by gas supply means 8, the gas supply through ducting 15, 16 of which (a) prevents plasma building up above the weld zone (which would decrease the beam intensity at the weld) but (b) holds some plasma in the region of the beam impingement on the wire so as to allow energy transfer to the adjacent walls. Butt welds or T welds can be made in this way, even in plate material, in a single pass from one side. The technique thus permits the arrangement of work stations on a production line to be simplified and rationalized when making up multiweld repeat structural units e.g. in shipbuilding.
