Abstract: The invention concerns a method of producing fatty alcohols with an iodine number between 20 and 110 from vegetable oils, the alcohols consisting essentially of unsaturated fatty alcohols or mixtures of saturated and unsaturated fatty alcohols of the general formula (I): R1OH, in which R1 is a saturated or unsaturated straight-chain or branched-chain alkyl group with 8 to 22 carbon atoms. Using prior art methods, the triglycerides contained in the vegetable-oil raw materials are (a) decomposed under pressure into the constituent fatty acids and optionally esterified with methanol or (b) transesterified to give the fatty-acid methyl esters and (c) the fatty acids or fatty-acid methyl esters are hydrogenated to give fatty alcohols. The method is characterized in that the fatty acids, the fatty-acid methyl esters and/or their hydrogenation products are fractionally distilled and the first runnings taken from the distillation, the end product having an iodine number from 20 to 110. The invention also concerns fatty alcohols produced from vegetable oils having an iodine number from 20 to 95 and the use of fatty alcohols produced from vegetable oils in the manufacture of washing, rinsing and cleaning agents as well as hair-care and body-care agents.

Abstract: A hand held tool for the removal of a cured bead of caulk, sealant or other previously fluent material from a joint between substantially perpendicular surfaces. The tool comprises an elongate handle with two working heads. The primary working head at one end of the longitudinal axis of the handle features a chisel-like point angled down from the upper face of the handle and extending between two symmetrical flanking planes which are acutely angled to each other and also spread from the body of the handle.      The planes are bevelled to form sharp edges for scraping surfaces during an operation to remove a bead whilst the chisel-like point chisels the body of the bead from the joint. Axially opposite the primary head the second working head is essentially an angled chisel-like point extended from the upper face of the handle and is used to chisel, pick or gouge a bead from a joint.

Title: Lightweight intervention system for use with horizontal tree with internal ball valve
Inventor: EDWARDS JEFFREY CHARLES
IPC: E21B33/035
Filed: 1996-06-21
Granted: 2002-08-06
Abstract: A lightweight intervention apparatus is described for use with a single bore  intervention operation and which is suitable for use with a sub-sea horizont al tree with a tree cap and integral ball valve. The lightweight intervention apparatus is adapted to be coupled to the horizontal tree and that when so coupled the integral ball valve within the tree can be actuated via the intervention apparatus and cycled between an open and a closed position. The  annulus line within the horizontal tree is adapted to be coupled through the  lightweight intervention apparatus to a separate annulus line such that the annulus line is separate from the main bore to facilitate control of the annulus for certain well functions. A significant advantage of this arrangement is that the internal diameter of the main bore is not reduced in  any way by apparatus or equipment for separating the annulus line from the main bore so that full bore diameter may be used. The lightweight interventi on apparatus includes a horizontal tree connector for mating with the sub-sea horizontal tree, a structural outer housing coupled to the horizontal tree connector and in which is located a sub-sea test tree and an upper top quick  connect/disconnect connector which includes a sub-sea test tree latch within  a pre-loaded external typeconnector.
