Patent ES-407971-A1 (ES)
Title: Method of inserting fuel rods into individual cells in a fuel element grid
IPC: G21C3/356
Filed: 1972-10-25
Abstract: An illustrative embodiment of the invention provides a fuel element assembly technique that facilitates the insertion of a fuel rod into a cell which is formed by a resilient grid structure. Initially, a cam is introduced into the cell. The inserted cam is rotated to deflect the grid surfaces that comprise the cell walls. This deflection prevents a leaf-spring mounted detent formed in the grid surface from extending into the path of the fuel rod. A key with a dimension that generally matches the deflected grid is inserted into the cell in order to engage the temporarily bowed grid surface. The inserted cam is rotated back to the initial orientation relative to the cell configuration and is withdrawn from the grid structure. The deflecting key lodged against the bowed grid surface, however, sustains the deflection in order to enable the fuel rod to be inserted into the cell without being abraded by the detent. After fuel rod insertion, the matching dimension portion of the deflecting key is disengaged from the grid surface and the key is withdrawn from the cell to release the leaf spring and allow the detent to clutch the fuel rod.

Title: Color television receiving system utilizing multimode inferred highs correction to reduce color infidelities
IPC: H04N9/77
Filed: 1978-06-30
Abstract: A color television receiving system for NTSC-type signals is provided with signal processing circuitry and methods for reducing the visibility of color and luminance infidelities, such as incorrect or inverted highs, over-modulation and rectification which are visible in regions of sharp transitions from one color to another or in regions of concurrent high color saturation and significant high frequency detail. Such infidelities are substantially reduced by effectively supplementing either the chrominance or the primary color signals with inferred high-frequency chrominance components derived from signal information discovered to be inherently available in NTSC-type signals and their implicit constraints. Specifically, in one form of the invention it has been found that in regions of sharp color transitions and in regions of high color saturation, relevant high frequency chrominance components can be scaled from the high frequency portion of the received monochrome signals in accordance with different respective scaling algorithms. A receiving system is provided with multimode inferred highs correction circuitry responsive to a received NTSC-type signal for automatically deciding which, if any, correction modes are appropriate for a given time and frequency region of the received signal and automatically enabling correction circuitry for providing the appropriate inferred high frequency correction signals.
