Filed: 1990-05-30
Abstract: CATALYTIC DEWAXING PROCESS FOR   PRODUCING LUBRICATING OILS                           ABSTRACT      Lubricant  oils of low pour point and improved oxidation stability are produced by catalytically dewaxing a lube feedstock over a zeolite dewaxing catalyst such as ZSM-5 in the hydrogen or decationized form and without a metal hydrogenation component.  The use of these catalysts enables products of excellent oxidative stability to be obtained and reduces the catalyst aging rate  in the  first and subsequent dewaxing cycles to values below 5°F (2.8°C)/day.  The duration of the dewaxing cycles may be extended, particularly in the second and subsequent cycles after hydrogen reactivation.

Abstract: A coupler 10 consists of a length of cross-linked polyethylene pipe having a spiral groove 16 cut in its outer surface and another spiral groove cut in its inner surface.  A heating element 18 is wound in the groove.  The coupler is expanded mechanically so as to have an easy fit over the ends of polyethylene pipes 12, 14.  The heater element 18 is energised and the coupler shrinks and forms fusion welded joints between itself and the pipes.  No preparation of the pipe ends is necessary because the serrated inner surface cuts through the oxidised skin and bonds to material beneath the skin.  The coupler is especially advantageous in large sizes of 500 mm or above.  Instead of an electric heater, radiant energy, eg infra red or light is used to heat the coupler.  For example, an array of reflector lamps can be used circumferentially located around the coupler.

Title: Amorphous silicic acid, process for its preparation and anti-blocking agent
Inventor: SOBOTTKA RICHARD
IPC: B29L7/00
Filed: 1992-05-13
Abstract: Abstract:     A modified amorphous  silica is described which,  apart from optionally present usual additives,  comprises 40 to 85 wt-% silica and 60 to 15 wt-% paraffin, silicone or vegetable oil and/or  ethylene  glycol.  The  modified  amorphous  silica  is prepared by bringing together, apart from optionally present usual  additives,  silica with  such  a  quantity of paraffin, silicone or vegetable oil and/or ethylene glycol that the fin-ished, modified silica has a paraffin, silicone or vegetable oil and/or ethylene glycol content of 60 to 15 wt-%. The modified amorphous silica is suitable as an anti-blocking agent, which can be advantageously prepared as concentrate (masterbatch). Surprisingly, upon preparing such a concentrate the melt-flow index hardly falls compared with the melt-flow index of the polyolefin which forms the basis of the concentrate. Thus it is possible to incorporate large quantities of the modified silica into the concentrate in very homogeneous distribution. This in turn has a favourable effect on the use of the concentrate for the manufacture of films.
