Abstract: A method of processing oily sludge to remove a substantial proportion of the water and hydrocarbon content therefrom to form a solid cake of waste material that is suitable for disposal in land fill sites. The method involving, firstly promoting flocculation in a batch of waste material by mixing in a flocculating agent. The flocculated waste material is then pressing at a first pressure to extract substantially all the free water within the mixture. After the first pressing the waste material is subjected to a second pressing at a second pressure to extract a substantial proportion of hydrocarbon material and further water from the mixture, thus leaving a solid cake of waste material. The invention also considers additional processing steps to maximize the level of hydrocarbon material reclaimed from the waste material.

Abstract: An assembly for use in connecting optical fibers includes a housing (12) for optical fiber joints and a fiber routing device (70) associated with the housing. The housing has a first inlet (41) for receiving optical fibers from a primary side of an optical fiber network and a second inlet (13) for receiving optical fibers from a customer side of an optical fiber network. The fiber routing device (70) has an outlet (78) for feeding fibers from the customer side of the optical fiber network into the second inlet (13) and two inlets (72, 74) for receiving the customer-side optical fibers for feeding to its outlet.

The guide arrangement comprises at least two guide devices 14.

Abstract: An outside diameter finishing tool (10) has an outer shell (16) and an inner annular abrasive layer (22) for precision finishing the outer surfaces of generally cylindrical workpieces. The inner layer (22) of the tool (10) is made of superabrasives and defines the cutting size of the tool (10). The inner layer (22) cuts simultaneously around the full periphery of a cylindrical workpiece rotated within the tool (10). A slot (14) is provided through the tool (10) to allow for radial adjustment of the cutting size of the tool (10).

Abstract: The invention relates to a process of applying a polyhydroxy high molecular weight polymer or like material to a substrate, comprising adding to a solution of such material in anionic form a flocculent of oppositely charged form in order to insolubilise such material, and thereafter applying such insolubilised material to said substrate. The invention has particular application in respect of production of paper by adding to the slurry supplied in paper production of an anionic starch and a cationic flocculent in predetermined amounts. The cationic polymer is preferably added prior to addition of the anionic starch. The cationic polymer preferably has a molecular weight of 150,000 or more and the anionic starch is preferably added in an amount of from 75% to 125% of the reaction ratio amount. Preferably, the cationic polymer flocculent is added in an amount of 0.5 kg or more per 1,000 kg of paper substrate and the anionic starch showing an amount of 2 kg or more per 1,000 kg of paper substrate.

Abstract: An installation 10 comprising a line 12 extending between and suspended from a plurality of spaced apart aerial suspension locations 14 defines a passage for an optical fiber unit. The line comprises a plurality of elongate tensile resistant tubes 18 connected end-to-end by respective connectors 20. The line is secured to each suspension location by respective securing means 22 which are secured to said line at two spaced apart locations 28, 30 thereon such that the portion 26 of said line between these locations is untensioned and includes a connector 20. The securing means 22 is adapted to allow tensioning of the portion 26 of said line when the tensile load on the line adjacent thereto on either side of said suspension location reaches a first predetermined amount, and the connector 20 is adapted to cause the end-to-end connection of the tensile resistant tubes 18 connected thereby to break when the tensile load on said portion reaches a second predetermined amount.

Abstract: A method for removal of magnetic ink from pulp stock formed from xerographic and laser printed paper waste comprising feeding such pulped paper waste past one or more magnets for removal of all or substantially all of such magnetic ink. The magnetic ink can be removed by capture or deflection techniques. The preferred pulp slurry has a concentration of 4% or less by weight pulp. The preferred magnetic force to be applied utilizes background magnetic fields in excess of 2000 Gauss and a field gradient in excess of 500 Gauss/cm. Also, a method for improving the recyclability of paper waste having ink thereon which does not normally contain a magnetic component, by utilizing one or more magnetic carriers in the formulations of the printing ink utilized.
