Abstract: ABSTRACT OF THE  DISCLOSURE           A jumper cable is formed from conven-tional ribbon cable having parallel conductors embedded in insulating material, either by lami-nating insulated or uninsulated conductors between plastic films, by extruding a plastic film around insulated or uninsulated conductors, or by bonding insulated conductors together, and subsequently separating the resulting individual insulated con-ductors at spaced intervals, forming a jumper of increased flexibility and reformability for use in confined spaces, without the need for subsequent removal of any part of the ribbon cable.  The rib-bon cable is preferably formed in sections, each section containing an oblique section of separated conductors, and separated by an oblique stripped area of uninsulated conductors, adjacent insulated cable sections being offset from each other.  The resulting cable is then preferably folded at a stripped area, to form a V-shaped offset reform-able jumper which may he easily reformed and reoriented after installation to fit into a con-fined space, while also having sections of unmodi-fied ribbon cable serving as support sections maintaining the individual conductors at predeter-mined parallel spacing to facilitate interconnec-tion and to prevent the individual conductors from becoming tangled.  The jumper may be used to con-nect two devices that are side by side, or arranged in a V-shaped or W-shaped arrangement, as well as for connecting devices which are aligned.

Abstract: TITLE OF THE INVENTION                    CUTTING ASSEMBLY                ABSTRACT OF THE DISCLOSURE           A cutting assembly is provided for use in cutting vegetable products, such as potatoes and the like, into a longitudinally extending central core and a plurality of longitudinally extending outer strips having a generally arcuate cross section.  The cutting assembly is mounted along an hydraulic flow path defined by an inlet pressure conduit for passage of the product one at a time at a rela-tively high velocity into cutting engagement with a core knife and a plurality of strip knives and for separation of the core and the outer strips for respective flow along an inner core discharge conduit and a concentric outer strip discharge conduit.  The cutting assembly is supported within an assembly housing between the inlet conduit and the discharge conduits with the core knife having a cylindri-cal shape for mounting at the upstream end of the core discharge conduit and defining a circular leading cutting edge along the axis of the flow path.  The plurality of strip knives are angularly arranged between the core knife and the assembly housing to extend radially therebetween for supporting the core knife in position and to define radially extending leading cutting edges for engaging the product. The core knife and the strip knives cooperate with the housing to define flow paths through the cutting assembly of substantially constant cross section for passage of the appropriate product pieces without substantial reduction in the hydraulic pressure applied thereto.

Abstract: ABSTRACT The invention relates to an ink ribbon adapted to be overwritten in overlapping manner and consisting of a carrier foil to which is applied an ink-releasing coating in the form of a plastic matrix with ink pigment dispersed therein and an ink paste, on a mineral oil base, containing fillers and wetting agents.  The ink paste oil base is a mineral oil containing 25 to 40% of aro-matic hydrocarbons in which 30 to 40% of the saturatedly bonded C-atoms are cycloaliphatically combined.  The wetting agent used is from the fatty amine salt group, while the filler is a finely divided, storage effective filler having a large internal surface   The viscosity of the ink paste is adjusted to a range of 4000 to 10,000 mPa.s (at 20°C).  The filler is preferably kieselguhr, precipitated silicic acid, activated char-coal and/or burst hollow spheres having a particle size distribution of 0.2 to 10 µm, and the wetting agent is preferably a fatty acid salt of a fatty propylene diamine of the general formula R-NH-(CH2)3-NH2.  This ink ribbon is particularly suitable for high speed type wheel printers and is characterized in that it permits a more than five-fold overstrike with uniformly deep black and sharp-edged script intensity.

Abstract: ABSTRACT OF THE DISCLOSURE           An injection mold for molding plastic needle-point sheets which have a plurality of aligned rows of perforations which define plastic threads therebetween in a lattice configuration.  The mold has engageable top and bottom mold body halves with open uniform mold channels formed in each half in a lattice configuration wherein the channel lattices of the mold halves cooperatively mate with each other upon engagement to define a mold cavity therebetween for the molding of the needlepoint sheet.  The lattice channels in the mold body halves are constructed whereby the lattice channels in one half define a greater total volume than that of the other half, such that the greater volume of plastic to be molded in the mold cavity is received in the ejection half of the mold.  In order to facilitate removal of the molded sheet from the mold, the lattice mold channels in the mold body halves are contoured to define a resultant cross section of the thread of a needlepoint sheet to be molded which is polygonal.  In order to compensate for possible misalignment or offset of the mold halves during the molding operation, the cross-sectional opening width of the lattice mold channels in one mold half are greater than that of the other mold half to provide an intentional mating mismatch between the mold channel openings of the respective mold halves.     1.

Abstract: ABSTRACT     A multiple-zone   fluidized bed  conversion process and apparatus for producing light distillate liquid and fuel gas products from heavy hydrocarbon feedstocks.  The feedstock is introduced  into  an  upper  fluidized bed   cracking  zone maintained  at a temperature  of  900-1400°F  for  cracking reactions, and resulting tars and coke are deposited on and within a particulate carrier material therein.   The carrier material descends through a stripping zone to remove tars and then into a lower fluidized bed gasification zone, which is maintained at a temperature of 1700--2000°F by 02-containing gas and steam introduced therein to gasify the coke and produce a reducing gas.   The stripping zone contains coarse packing material which is supported by a refractory annular-shaped grid.  The decoked hot particulate carrier is recirculated by a transport gas upwardly through a central refractory-lined conduit to the upper bed.  Such recycle of the carrier solids is controlled by a refractory-lined  gas-cooled valve.
