Abstract: Abstract The present invention relates to a method and apparatus for pumping high consistency pulp, which invention is especially suitable for pumping high consistency  fiber suspensions  in the pulp and paper industry.            One of the problems in the prior art techniques has been the difficulty of bringing high consistency pulp to the impeller of the pump or like, because high consistency pulp tends to form strong fiber network, which stops the pulp flow. A method has been developed as a solution to the problem,  in which liquid is discharged from pulp during the pumping process and the liquid is fed back to the pulp to be pumped upstream of the pumping. This method is enabled by an apparatus, in which at least part of the surfaces of the pump  (1)  are arranged with  filter surfaces  (6,  7,  8,  9,  10),  through which the liquid  separated  from pulp is returned either directly  in front of the suction opening (11) of the pump (1) or to some other suitable place in the mass tower.

Abstract: ABSTRACT OF THE DISCLOSURE      An automatic sorting system for automatically sorting objects comprises a control guide which branches off into a plurality of branches having different depths, moving members which have rod-like pins which are guided by the control guide and divert the objects in a transverse direction, and a pin-moving device, such a cam, for moving the pin of each moving member vertically in response to a signal generated by a detecting device.  The cam has two arc portions of different radii which depress a transversely slidable rod of the moving member.  The moving member follows a path determined by the control guide having a depth corresponding to a depending length of the rod of the moving member, and is guided along this control guide groove.  With this system, good or defective articles are automatically diverted in a transverse direction by the moving members, so that the objects are sorted based on their transverse positions.

Granted: 1992-01-28
Abstract: PATENT       Abstract of the Disclosure A process and apparatus for the production of heavier hydro-carbons from one or more gaseous light hydrocarbons is provided.          The process comprises reacting the gaseous light hydrocarbons by autothermal reforming with air in the presence of recycled carbon dioxide and steam to produce a synthesis gas stream containing hydrogen  and  carbon  monoxide. The  synthesis  gas  stream  is reacted in the presence of a hydrocarbon synthesis catalyst con-taining cobalt to form heavier hydrocarbons and water from the hydrogen and carbon monoxide.  The heavier hydrocarbons and water are separated, and the resulting residue gas stream is subjected to catalytic combustion with additional air to form a product stream  comprising  carbon  dioxide  and  nitrogen.    The  carbon dioxide is separated from  the nitrogen to produce a nitrogen pro-duct  stream,  and at  least  a portion  of  the  separated carbon dioxide is recycled to the autothermal reforming step.

Abstract: "VAPOUR PLUG FOR TEMPORARILY SEALING A PIPELINE"                   ABSTRACT OF THE DISCLOSURE         The vapour plug can be inserted into an open end of a pipeline.   It comprises a hydraulic cylinder carrying a vertically disposed, elastic, resilient seal ring.   The cylinder may be hydraulically actuated to expand the ring radially to seal the bore of the line.  The hydraulic lines to and from the cylinder chamber may be blocked to lock the plug in the expanded mode.  A plunger valve, responsive to pipeline pressure, controls a hydraulic fluid passage connecting the ends of the cylinder chamber.   When the plunger valve is in the closed mode, it prevents fluid moving between the chamber ends.   When the valve is moved by pipeline pressure to the open mode, fluid can move freely between the chamber ends, thereby permitting the ring seal to contract, to unseal the bore.   The plug may then be pumped down the line and recovered at a pig trap.
