Abstract: ABSTRACT       The present invention provides a process for applying a molten thermoplastic composition as a series of discrete droplets from a non-contact ink jet printing apparatus to form separate drops on a substrate moving relative to the apparatus, characterised in that the molten composition is thermally stable at the temperature of application and is applied at a temperature in excess of 100°C.  The invention can be used to apply the molten composition to a variety of substrates using on-demand or continuous non-contact ink jet application techniques.   However,  the invention is of especial use in applying thermoplastic inks to non-porous substrates using an on-demand ink jet printer.

Abstract: 12                  51,798 ABSTRACT OF THE DISCLOSURE         For removal of the contaminant deposits from a surface  such  as  a  tube  sheet of  a vertical  tube heat exchanger, as in a nuclear steam generator, having plural spaced heat exchange tubes connected to the tube sheet, a lance  is  radially  moved  along  the  tube  sheet  between parallel rows of tubes.  The lance carries a nozzle for ejecting a stream of high pressure cleaning fluid toward the sludge deposits, the nozzle acting cyclically to sweep the stream throughout a range of directions centered about the nozzle axis.  The nozzle may include diverting streams for deflecting the cleaning fluid stream, with the divert-ing streams either being generated by a fluidic oscillator or being fed back from the outlet portion of the nozzle.          Alternatively, pivoting vane means may be provided in the nozzle to divert the cleaning fluid stream.

Abstract: ABSTRACT            "MAKING ELECTRICAL CONTACT BETWEEN METALS       AND RESISTIVE ELEMENTS"     In an electrical device comprising first and second members having different resistivities, a thin contact layer of intermediate resistivity is provided between the first and second members.  The contact layer, (which may comprise a conductive polymer) is intimately bonded to the member of highest resistivity (which may comprise a second conductive polymer) e.g., by a printing process.  The member of lowest resistivity may comprise a third conductive polymer, in which case it may be intimately bonded to the intermediate contact layer, e.g., by a printing process, or it may comprise a metallic member, in which case good electrical contact may be made merely by pressing the metallic member against the contact layer even when the contact area is large and/or long, and even when the pressure is sufficiently low to permit, if necessary, relative movement of the metallic member and the contact layer without disrupting the bond between the contact layer and the resistive element.  A preferred device comprises four or more members of different resistivities.  The members are arranged adjacent each other in order of decreasing resistivity.  The least resistive member preferably comprises a metal and the other members conductive polymer materials.                          (Figure 5)

Abstract: ABSTRACT           Apparatus for making bags from a two-ply web of thermoplastic material comprises feed rollers for intermittently pushing forward the web in steps corresponding to a bag length into a gap between welding beams, which comprise an upper welding beam provided with drive means for lifting and lowering said upper welding beam.  The apparatus also comprises a severing knife, which extends below the web and parallel to the lower welding beam beside the same and is secured to a endless tensile element, which revolves around pulleys. The upper welding beam is adapted to force down the web into the cutting range of the severing knife.  The feed rollers directly precede the welding beams and are disposed in rows of upper and lower guide rods or air-blowing tubes, which rods or tubes are arranged like combs and cause the web to move between said rows in a plane disposed above the path of the knife as the web enters the gap between the opened welding beams. The lower welding beam is fixedly mounted on the frame.  The continually revolving knife moves through that plane for the web which is defined by the lower welding beam as the transverse seam weld is made. Means are provided which are actuated as the upper welding beam is lowered and serve to impart a pivotal movament to the lower row of guide rods or air-blowing tubes toward the lower welding beam.
