Title: Stereoscopic camera
IPC: G03B35/10
Filed: 1977-06-22
Abstract: A stereoscopic camera has two lens-and-mirror trains for imposing a pair of stereoscopic images in side-by-side relationship on a common photographic film. Each optical train comprises a pair of oblique mirrors and plural lens elements. However, the final or objective lens of one train is at a right angle to that of the other train, one objective lens having its axis parallel to the lines of sight and the other objective lens having its axis perpendicular thereto, this latter lens preceding its final oblique mirror and the former lens following the final oblique mirror, in their respective optical trains. In this way, the depth of the camera, parallel to the lines of sight, is substantially reduced and the sizes of the mirrors are substantially reduced. Stopping diaphragms are provided for each optical train, at right angle to each other, and mounted on a common block that is movable past the optical axes to permit the selection of the diaphragms of different sizes.

Title: Assembly of piezoelectric element unit and sheet metal mount for ignition device
IPC: H01L41/113
Filed: 1979-04-06
Abstract: A piezoelectric element unit and sheet metal mount therefor has a window opening for readily mounting the unit therein without the necessity for using tools and for stably holding it despite repetitive beating by the hammer of the actuation mechanism. The unit is formed as a cylinder with a pair of opposite grooves axially extending in or on the circumferential surface of the unit so as to engage the side edges of said window. When the grooves are cut directly in the circumferential wall of the unit, a second window formed to be interconnected with the aforementioned window for mounting the actuation mechanism is designed to have a width longer than the diameter of the unit so that the unit is first located in the second window and then slid into the first window. When the grooves are formed by two rows of upper and lower axial protrusions therebetween, notches are formed at the opposite edges of the window so that either of the upper and lower protrusions may clear the notches in order that the unit may be slid into its final position.

Patent ES-8100709-A1 (ES)
Title: Fluidic oscillator device.
IPC: C09J7/02
Filed: 1980-03-08
Abstract: The fluidic oscillator (14) includes a resonant fluid circuit having a fluid inertance and a dynamic fluid compliance. The inertance is a conduit (4) interconnecting two locations (16a, 16b) of a chamber on each side of a working fluid jet issuing into one end of the chamber (3), the inertance conduit transfers working fluid between the two locations. Through one or more output orifices (10), located at the opposite end of chamber (3), the fluid exits from an exit region (11) which is shaped to facilitate formation of a vortex (the dynamic compliance) from the entering fluid. The flow pattern in chamber (3), specially the vortex in exit region (11) provide flow aspiration on one side and surplus of flow on the opposite side of chamber (3), which effects accelerate and respectively decelerate the fluid in the inertance conduit (4) such as to cause reversal of the vortex after a time delay given by the inertance. The vortex in the exit region will cyclically alternate in velocity and direction of rotation to direct outflow through the output orifice such as to produce a cyclically repetitive side-to-side sweeping stream whose direction is determined, at any instant in time, as a function of the vectorial sum, at the output orifice, of the tangential vortex flow spin velocity vector and the static pressure vector and the dynamic pressure component, both directed radially from the vortex. By changing these parameters and by appropriately configuring the oscillator, sweep angle, oscillation frequency, distribution, outflow velocity, break up into droplets, etc. can be controlled over large ranges.
Patent ES-8202364-A1 (ES)
Title: kit and test surface material therefor.
IPC: G01N33/58
Filed: 1980-10-15
Abstract: An assay method and compositions are provided for determining the presence of an analyte in a sample. The analyte is a member of an immunological pair (mip) of immunogens-ligand and receptor. The method has two basic elements: a solid surface to which one of the members of the immunological pair is bonded and a signal producing system, which includes a catalytic member bonded to a mip, which signal producing system results in a measurable signal on said solid surface related to the amount of analyte in the medium. The signal generating compound is produced without separation of the catalyst labeled mip bound to the solid surface from the catalyst labeled mip free in solution. In a preferred embodiment, an enzyme is bonded to a mip which acts in conjunction with a solute to produce a signal generating product which binds preferentially to the solid surface when the enzyme is bound to the surface, resulting in a signal which is readily differentiated from signal generating compound produced by the catalyst and solute in the bulk solution.
