Abstract: EMBOSSED ORIENTED FILM                      Abstract of the Disclosure Oriented or strength-enhanced embossed film is produced by introducing a thermoplastic film having an inert liquid lubricant covering its surfaces into the nip between at least one pair of rotating compression rolls under sufficient pressure to reduce the thickness of the film, and simultaneously embossing at least one of the film surfaces within the nip.  While various inert liquids may be used as the lubricant, use of water for this purpose is preferred.  The lubricant is believed to provide a hydrodynamic wedge at the film-compression roll interfaces, and for best results it is preferred to spray the lubricant (most preferably, water) into both incoming sides of the nip of the compression rolls.

Abstract: Abstract of the Disclosure An apparatus for machining a workpiece such as a crankshaft provides a superior combination of low initial and rebuilding costs, high flexibility in tool  changeover and alteration of configuration, yet minimizes floor space and noise level while allowing the combining of several machine operations in a single step.   The  apparatus also permits the use of optimum cutting speeds, cutting tool feeds, cutting tool composition and cutting tool dimensional tolerances.  The apparatus includes a lathe bed to which the crankshaft is mounted and rotated at a variable rate of speed, as well as an arbor disposed parallel to the axis of rotation of the workpiece, rotatable in the same direction at a variable speed.   At least one cutter disk is fixedly mounted to the arbor.  The disk has a plurality of cutting tool disposed about part but not all of its circumference,  the tools being located at a generally increasing distance from the  center  of  the  disk  in  a  stepwise  fashion.    The circumference of the disk also includes a second cut out portion between the radially outermost and radially innermost tools.          The disk is rotated to bring first the outermost and then the sequentially more inner tools into contact with the spinning workpiece, in order to machine it.   The workpiece and disk are each rotated at programmed, varying rates in order  to optimally match  the   tool  feed  rate  and  the workpiece surface linear speed for each machining operation, for example, rough cutting, finish cutting, dimensioning and the like.  Once the radially innermost tool has cut the workpiece, the cut out portion of the disk circumference permits ready removal of the workpiece from the lathe bed without requiring reciprocation,  reversal or movement of the disk out of the way.   The invention thus advantageously avoids the  tool  slides  or  reciprocating  carriers,   and  the associated wear, poor tolerances, extra mechanisms and the like encountered with prior art broaching tools.

Abstract: 54,193 ABSTRACT OF THE DISCLOSURE The present invention is a system that takes a drawing definition produced by a CAD/CAM system lo and produces a debugged part program.   The drawing definition is used to produce a sequence of processes which will produce the part.   The drawing definition is a list of the surfaces which create the part.   The list is scanned by a process planner 14 and a list of primitive shapes and transition points in each shape is created.   The transition points are used to create a process tree defining regions for machining.   The tree is populated with region boundaries that are used to designate machining operations.   The boundaries are then used to select particular processes based on the shape to be machined during the operation by traversing a shape tree looking for a match.  The process selection also specifies tools, feeds and speeds necessary for rough machining the part.  During process selection the size of the region is also determined and from the tool selection, the number of rough cutting passes are determined for number process.  The sequence of the processes is determined by scanning the process tree and concatenating like processes and, within the like 32                      54,193 processes, the processes with the same tools and preferred tool direction.  A finishing process is produced by creating and scanning a continuous part surface to produce contouring cuts.  An appropriate machine is selected based first on the rough stock dimensions of the stock to be used to make the part and then on the number of tools that can be held by the machine and possible feed speeds of the machine. The sequence of processes and process parameters are used by a code generator 16 to complete macrocalls corresponding to the processes.  The resulting part program is transferred to a code processor 18 which produces the machine tool code for the particular machine 20 selected.

Abstract: An antenna system and technique for laminating a di-electric substrate (14) to an antenna housing (12) which prevents separation of the dielectric substrate (14) from the housing (12). This is accomplished by confining an antenna assembly (10) inside a laminating fixture (24). Heat is then applied to the fixture (12). This causes the dielectric substrate (14) to become somewhat plastic and also to expand. This expansion results in great pressure being exerted between the dielectric (14) and the housing (12). When the assembly is allowed to cool, the dielec-tric (14) adheres to the housing (12). This prevents sepa-ration of the housing (12) from the dielectric (14). The result is an antenna assembly (10) which can withstand large temperature extremes without causing an air gap be-tween the dielectric (14) and the housing (12) which would distort the electrical signal transmitted or received by the antenna.
