Abstract: ABSTRACT OF THE DISCLOSURE            A cover having a substantially elliptical periphery is fitted into a substantially eliptical opening in a hous-ing.  Along the two longer sides of the elliptical periphery first half-throats or grooves of semi-circular cross-section are formed whereof their open sides face the open sides of second half-throats or grooves of semi-circular cross-section formed along the inner edge of the two longer sides of the elliptical opening.  Each combination of a corresponding first and second half-throat forms a respective substantially complete throat along which corresponding cylindrical lock-ing bars disposed therein extend and prevent up and down dis-placement of the cover relatively to the housing.  Each throat is interrupted intermediate its opposite ends by an elongate recess in the housing, allowing said bars to be in-serted into the throat through the recess.  The recesses and the gap between the cover periphery and the inner edge of the housing opening are occupied and covered by an elliptical hermetic seal.  The cover is fixed without bolts to the housing which can be a valve housing, particularly of an underground valve or one subject to a corrosive atmosphere.

Abstract: DIGITAL SCAN CONVERTER WITH  RANDOMIZED DECAY FUNCTION     ABSTRACT OF THE INVENTION       Analog video information with a wide range of radar characteristics is converted by a digital scan converter into a standard TV format.  The analog video information is converted to digital PPI data and stored in a buffer.  The digital PPI data is consecutively integrated on a pulse to pulse basis to eliminate noise.  The digital PPI data is then stored in an image memory (RAM).  The polar coordinates of each digital PPI data sample are converted to an address of equivalent X, Y coordinates wherein each point along a TV line is an X coordinate and each TV line is a Y coordinate.  This address defines the location at which the data is stored in the RAM.  Each address of X, Y coordinates uniquely defines a cell in the RAM which is three bits deep, describing eight intensity levels.  Data is read from the image memory in time sequence with a TV synchronization signal for display on a TV monitor.  During TV memory cycles, an N element word is read from the RAM to drive the video output circuits, processed through a programmable read-only memory programmed in accordance with a randomized decay function and written back into the same memory address.  During radar cycles, an N bit word is read from the image memory and one bit in each word is updated in accordance with the new radar data.

Abstract: METHOD AND APPARATUS FOR INTRODUCING PROGRAM CHANGES IN PROGRAM-CONTROLLED SYSTEMS            Abstract An arrangement for using either an original program or a modified version of the program in a program-controlled system.  Each time a modified version of a selected program function is stored in the system, it is tagged with a function sequence number and the original program function is retained in the system.  Each time a program process is initiated, it is tagged with a process sequence number.  The two types of sequence numbers are assigned from a common source.  Whenever the selected program function is called by a program process, a comparison is made between the process sequence number and the function sequence number.  If the comparison indicates that the process was initiated before the modification was stored in the system, the original version of the selected program function is executed; otherwise; the modified version of the selected program is executed.  Thus, either the original version or the modified version is available consistently throughout the active life of a process.
