Patent ES-462511-A1 (ES)
Title: Tomography scanning
IPC: G01N23/08
Filed: 1977-09-21
Abstract: A fan-shaped beam (13) of hard radiation is emitted from a radiation source (11). This fan-shaped beam penetrates an examination region (14) and then impinges on a row of detectors (16) in which the radiation values corresponding to the transparency in the cross-section of the examination region are detected. The detectors (16) are situated on a circular track concentrically relative to the axis of rotation of the radiation source (11), and thus receive as they rotate a sequence of measured data for specific cross-sectional regions in each case, which are displayed via evaluation devices (17, 21). This device permits high-power scanning with a high resolution, there being no need for precise matching of the amplification between the individual detectors. It is possible for the detectors to be routinely calibrated without the patient having to leave the measurement region.

Patent ES-477116-A1 (ES)
Title: Improvements to pressure slide valves for automatic cylinders.
IPC: F16K/
Filed: 1979-01-24
Abstract: The improvements to pressure slide valves, according to this invention, are essentially characterised by the fact that each valve consists of a valve body equipped with an axial opening closed at its lower part, which is in contact with two pipes, one fluid inlet pipe and the other an outlet pipe, which are internally separated by a valve seat which operates in conjunction with a sealing facility consisting of a widening of a rod which on exiting the valve body through a sealing nut is housed coaxially in a capped opening in the cylinder's piston, so that when this moves, a nut fitted in its lower part can establish contact with a butt, preferably formed by another nut fitted on the rod, thus moving the rod and opening the valve. The pressurised fluid enters through the inlet pipe directly to the central opening of the valve to cause the exit to be sealed due to the difference in areas on which the pressure acts on either side of the sealing element and on the cylinder chamber through a pipe equipped with a non-return valve. The removal of the pressurised fluid from the inside of the cylinder occurs when this is allowed by the valve's sealing element through a pipe which joins this cylinder chamber to the central opening of the valve body with the insertion of a stopcock which enables the speed of the fluid outflow and thus the recoil speed of the cylinder's piston to be regulated. The rod is equipped on its lower part with an axial opening into which the fluid enters through a small orifice in order for the chamber which forms in the upper part of the rod to fill with fluid and to act as a cushion for this rod on the recoil.

Patent ES-483568-A1 (ES)
Title: Frequency chirp in isotopically selective photoexcitation
IPC: B01D9/02
Filed: 1979-08-22
Abstract: Method and apparatus for inducing isotopically selective photoexcitation of atoms in at least first and second energy steps. The total energy change accomplished by the two energy steps is provided with isotopic selectivity at precise resonance for the two steps. In an isotope separation system in which an environment of particles of plural isotope types is created, isotopically selective photoexcitation from laser radiation is shown to produce a great improvement in excitation efficiency where the radiation is controlled in the aggregate of plural photons to achieve precise resonance over the plurality of the degenerate energy steps. Even with multimode excitation, precise resonance is only achieved for isolated atoms, and a chirp or frequency sweep is applied to one of several excitation frequencies to insure precise resonance at least once for each atom. In the case of excitation in plural transitions from plural low-lying energy through a generally common upper transition, the chirp may be applied to the radiation producing the common upper level transition alone.
