Abstract: ABSTRACT OF THE DISCLOSURE          An improved scroll type compressor unit is disclosed for the compression expansion and or pumping of fluids.  The main advantages of the improved compressor are:  fewer number of parts, continuous compression of fluid, improved sealing of the fluid pocket and reduced wearing of the spiral elements.  With this structure, fluid introduced into the compressor housing is taken into all pockets between both scroll members in order to effectively compress the fluid.  These advantages are achieved by controlling the entry of fluid into the compressor in a manner to divide it where one portion of the fluid is taken into a space between the outer end portion of the rotatable scroll member and the fixed scroll member with the other portion of the fluid being introduced into a space between the outer terminal end portion of the fixed scroll member and the adjacent portion of the rotatable scroll member.  This arrangement ensures that fluid introduced into the compressor housing is affectively taken into all fluid pockets between both scroll members.  This is achieved by having a first end plate on the fixed scroll member and a second end plate on the orbiting scroll member, with the first end plate at an upper portion thereof being provided with a first hole outside the wrap of the fixed scroll member and adjacent to the outer terminal end of the second wrap of the orbiting scroll member.  A second hole is provided at a position corresponding to the centre of the first wrap.  The first hole is connected through the suction chamber of the compressor to the fluid inlet port to thereby introduce the fluid from the inlet port into the first chamber, defined between the scroll members, while introducing the remaining portion of the fluid to the other side of the scroll members.

Abstract: ABSTRACT         Apparatus for continuously feeding and controlling wraparound carrier for packaging a plurality of articles or containers is disclosed.  The carriers are of the type having at least two draw-down and feed openings, one opening formed on each side thereof.  Each carrier is initially partially wrapped about a plurality of containers.  The carrier and container assemblies move along a guide track to the entrance of the carton draw-down (tightening) coveyor line of the pre-sent invention.  The conveyor line comprises a pair of con-tinuously moving timing chains having a plurality of draw-down lugs pivotally attached to and spaced apart along the chain.          Each lug includes a tongue portion adapted for insertion through the openings to feed and to draw down the side walls, and also to control the positioning and movement of the containers.  As the partially assembled carrier and containers enter between the moving chains, a cam follower portion of the lugs contact the camming rails, causing the lugs to sequentially pivot downwardly and into contact with the open-ings formed in the carrier.  The carrier is moved along the conveyor line with the lugs engaging the containers through the carrier apertures for positive control.  Downward pressure is applied by the lugs to the carrier, causing the carrier to be pulled down and tightened about the containers.  The lugs are pivoted out of contact with the carrier as the carrier exits the conveyor line to complete the assembly process.

Abstract: ABSTRACT OF THE DISCLOSURE          The resistance to mechanical degradation of poly-mer modified lubricating oils can be improved by reducing the elastic character of the fluids at a given viscosity and polymer concentration.  Stored energy per bond, which is the energy for degradation, and which is provided by the flow process, is related to this elasticity.  This stored energy can be reduced by altering the molecular weight distribution and molecular topology, i.e., macroscopic structure (linear, branched and ring structures) of the polymer.  When a polymer solution is deformed, part of the energy is expended as viscous dissipation (i.e. heat) and part causes deformation of the polymer molecules which stores energy rather than dissipating it.  The amount of energy the molecules can store is measured by their compliance, which indicates for example how much the chains will retract when the stress is removed.  A large compliance means that the molecules deform easily when stress is applied.  Stored energy per volume of solution is quantitatively related to the elasticity of the solutions through the compliance of the solution.  This solution compliance depends on the com-pliance of the polymer molecules and their concentration. Rules are formulated using the compliance which permit selection of MWD and molecular topology to maximize mechan-ical stability.  Nonlinear structures and particular MWD classes are claimed.

Abstract: VECTOR TO RASTER PROCESSOR                 ABSTRACT OF THE DISCLOSURE            In raster data plotting of graphic information, vector data comprising the plot is generated by the host computer via the user's appli-cation program. For maximum plotter efficiency and relief of host system time, vector to raster conversion is carried out by an offloading processor which receives vector data ordered in vector bands constituting the plot. Vector data in each band is received in random order and is initialized for vector computational values. The computational values for each vector are stored in parallel format in a vector memory in the initialized random order for subsequent retrieval in parallel format for vector to raster proc-essing of each scan line of the band and then restored in parallel format in the vector memory if the vector is still active. A vector type, desig-nating vector orientation relative to Cartesian coordinates, is one of the computational values for each vector. The time required for vector to raster conversion is further enhanced by processing each vector directly according to its vector type found in the microcode of the processor.
