Abstract: WAVEGUIDE APPARATUS AND METHOD FOR DUAL POLARIZED AND DUAL FREQUENCY SIGNALS          ABSTRACT OF THE DISCLOSURE           A waveguide apparatus guides a first pair of horizontally polarized transmit and receive frequency signals independently of and in parallel with a second pair of vertically polarized transmit and receive frequency signals.          The waveguide apparatus guides the two pairs of orthogonally polarized frequency signals between a feed horn and related transmitter and receiver units at the antenna of an earth station.  The waveguide apparatus includes a polarization junction for separating the pairs of frequencies by polarization and two frequency separators for separating the transmit from the receive signal in each polarized pair.  Each of the frequency separators has a planar filter with interspersed bandpass and band-stop structure located in one port and susceptance blocks located in another port for maintaining isolation be-tween the transmitter and receiver units.  The polarization junction is orthogonally coupled to the horizontal frequency separator by a coupling having symmetrical H-plane bends, E-plane bends and a Southworth junction which are effective in combination with septums in the polarization junction to produce inherent broadband operation without tuning.  The four port configuration with dual orthogonal polarizations and broadband operation permits dual path redundancy for communications users with only one antenna.  The waveguide apparatus is physically short and structurally robust, and all of the ports terminate at a common plane so that the waveguide apparatus can be and is used as a structural member for supporting all of the electronics within the antenna mount, and directly at the outlet of the waveguide apparatus.  The structure and operation of the wave guide apparatus enable  each of the transmitter and receiver units to be a replaceable unit which can be removed or replaced without interfering with the transmission or reception of any of the other three signals.

Abstract: ARITHMETIC UNIT FOR USE IN   DATA PROCESSING SYSTEMS                          Abstract of the Invention A data processing system using unique procedures for handling var-ious arithmetic operations.  Thus, in floating point arithmetic mantissa cal-culations the system uses a novel technique for inserting a round bit into the appropriate bit of the floating point result wherein a look-ahead carry bit generator stage is used for such purpose to reduce the overall mantissa calculation time.  Further, the system utilizes unique logic which operates in parallel with the floating point exponent calculation logic for effect-ively predicting whether or not an overflow or underflow condition will be present in the final exponent result and for informing the system which such conditions have occurred.  Moreover, the system utilizes a simplified tech-nique for computing the extension bits which are required in multiply and divide computations wherein a programmable array logic unit and a four-bit adder unit are combined for such purposes.

Abstract: ABSTRACT OF THE DISCLOSURE      The present invention relates to an improved system for suspending well casing in a subsea well head.  Each of a plurality of concentric casing strings and its hanger are directly and totally supported on the well head housing independently of all the other strings and their hangers by a plurality of expandable, load ring slips that are run into the housing in retracted position with and as a component of the previous casing's pack-off assembly.  Due to each casing string being supported by the well head housing independently of the other strings, the total load exerted by the casing strings, their hangers and well test pressure that the suspension system can support is significantly greater than that supportable by other systems of comparable size.  This increase is achieved even when lower strength materials are employed.  The improved load carrying capability of the system facilitates deeper drilling programs to be accomplished offshore from floating drilling rigs.
