Title: Steering gear with varying transmission ratio
IPC: F16H55/08
Filed: 1973-07-28
Abstract: A nut on a helically threaded steering shaft, held against rotation, carries a first set of involute teeth meshing with a second set of involute teeth on an adjoining gear sector which pivots on an axis skew to that of the shaft. The two sets of teeth have centers of curvature offset from the sector axis but aligned with that axis in a midposition in which they engage each other without play upon a shift of the nut to either side, the tooth clearance or backlash increases progressively while the transmission ratio either increases or decreases, depending upon the relative positions of the two centers of curvature and the sector axis. In a limiting case, the radius of curvature of one set of teeth is infinite.

Title: Positive safety control device
IPC: G21C7/36
Filed: 1975-12-11
Abstract: In a nuclear reactor protection system, the control device initiates reactor shutdown when the amplitude of a voltage signal delivered by a detector oversteps a range limited by two adjustable values.

Patent ES-461538-A1 (ES)
Title: Self-cleaning filter
IPC: B01D29/05
Filed: 1977-08-11
Abstract: A self-cleaning filter includes a housing having a compressible filter element and a compression spring for applying spring pressure to the filter element. Unfiltered fluid, at line pressure, is forced upwardly through the filter element. Spring tension is overcome by line pressure during normal filtering operations to compress the spring and allow the filter element to maintain a relatively uncompressed condition during filtering. The spring tension is sufficient to automatically compress the filter element when line pressure is shut off to squeeze the filter element and flush out filtered particles from the filter element into a chamber below it. Separate agitators in the chamber rapidly spin and move in a random pattern throughout the chamber to keep the walls of the chamber clean from filtered particles during filtering operations. The chamber may have an automatic drain valve which automatically opens when line pressure is shut off to discharge filtered particles from the housing.
