Abstract: Forging Method and Apparatus Abstract The present invention provides methods and apparatus improving the dimensional accuracy of forged components. Uniformity of like component details is sought and a specific object is to provide a die package for forming closely toleranced appendages integrally with a central disk structure from which the appendages extend.      In one effective embodiment incorporating concepts of the present invention, the forging dies include a station-ary die and a movable die comprising at least two separately movable elements which are mounted on a common axis with the stationary die.  A plurality of arcuate die segments are adjacently placed in cylindrical array about the stationary and movable dies.  The arcuate die segments form cavities of the inverse geometry of the appendages to be formed and in at least one embodiment are interlocked to prevent tilting of the segments in the die package.      The movable die elements are sequenceable to form a billet of material into a workpiece having an intermediate configuration, and subsequently into a workpiece of final configuration.  In at least one embodiment, pressure pads are disposed against one of the movable dies to prevent displacement of that die by the billet material as the intermediate configuration is formed.

Abstract: Abstract of the Disclosure A fixed bottom transition joint for suspended pipe risers includes a structural member.  This structural member is defined by a top surface having a predetermined diameter and by a parallel bottom surface having a diameter which is larger than the diameter of the top surface.  Further defining the structural member is an outer surface which extends between the top and bottom surfaces and optimally tapers from the bottom surface to the top surface.  Finally, an inner surface defines a longitudinal bore through the structural member.

Abstract: GEOMETRIC DESIGN FISHING ROD.            Abstract of Disclosure.          The principles of this invention apply to the incorporation of geometric forms in the tapering configuration of a fishing rod. These said geometric forms being either of sectional form, or achieved by a structural composition of varied material density within the rod shaft sections. A rod of such geometric design would have properties in the uppermost section that would favour directional movement. This would be merged with a section below that can flex to any angle with equal resistance, and this section will in turn be merged to a section which has properties to oppose flex by means of geometric principle. A rod so described will possess an inherant capacity to flex and recover, with a compressional and recoil action, that will favour the selected angle of the delivery stroke. The stroke of the cast will be made in a more decisive and efficient manner from a shaft of geometric design than a shaft which possess an equal radial flex character throughout its complete working length.

Abstract: ABSTRACT OF THE DISCLOSURE         An optical pattern tracer is disclosed, of the circular scanning type.  The interception of the pattern by the scan produces electrical outputs which are reduced to numerical values representative of their time of occurrence with reference to the scanning circle.  The numbers derived and the nature of the signal generated are then processed to indicate the direction of the pattern, presence or absence of command marks and combined with other reference inputs, such as kerf and direction of tracing used to control a drive mechanism to move the tracer around the pattern.

Abstract: ABSTRACT     A sweep control circuit and method for maintain-ing a constant swept frequency range of a voltage-con-trolled oscillator when switching between linear and non-linear sweeping functions is provided.     The sweep control circuit includes a linear ampli-fier and an antilogarithmic amplifier, each of which has an output voltage window that is matched to the linear dynamic range of the CVO. Independently select-ed  start and  stop voltages  are adjustable over the entire linear range of the VCO to set the lower and upper frequency limits as desired for either a linear or a logarithmic sweep. Log converters are utilized to map the linear start and stop voltages to logarithmic counterparts so that the VCO frequency does not shift when switching from one function to the other. This permits a single start frequency control and a single stop frequency control to be employed. A ramp voltage, which is appropriately scaled for both the linear and logarithmic  functions,  is  applied to sweep the VCO.          While the transfer functions of the log converters and the  antilogarithmic  amplifier are highly temperature dependent,  the topology of the sweep control circuit is such that in calculating the overall transfer func-tion the temperature terms are cancelled.

Abstract: ABSTRACT OF THE DISCLOSURE      A method and digital system for the compression and reconstruction of cultural data for use with display systems, such as a system for producing a real time moving map display of terrain, provides a modified footprint/common boundary technique for data compression in which the footprint extends forward of the last point generated along a line in the direction of the line to that point.  The particular scheme for compressed data reconstruction employs the storage of footprint data in such a manner that change in line direction information is automatically provided along with the necessary delta data information so that the direction of the line can be constantly updated as each point is generated.  The compression of area cultural features involves a double compression of data based on a common boundary approach and the linear compression techniques of the modified footprint technique.  In addition, in the reconstruction of compressed cultural data, changes in scale factor are accommodated along with feature deselection based on the selected scale factor.
