Abstract: 538,446. Ethereal nitrates. STANDARD OIL DEVELOPMENT CO. Feb. 8, 1940, No. 2476. Convention date, March 30, 1939. [Class 2 (iii)]  Secondary aliphatic nitrates are produced by nitrating compounds containing a secondary alcohol group at a temperature not above -10‹C. using a nitration mixture containing at least 50 per cent. excess of nitric acid and also sulphuric acid and water, the molecular ratio of water to sulphuric acid being not greater than 1.6 + .004 (E-50) where E is the percentage excess of nitric acid. A part of the sulphuric acid may be replaced by an acid of phosphorus or a water-soluble fatty acid, such as phosphoric or acteic acid, in which case the lower limit of nitric acid may be used ; otherwise the excess of nitric acid should be at least 100 per cent. Examples describe the production of the nitrate of secondary amyl alcohol, and it is stated that other alcohols that may be used are substituted and unsubstituted mono- and polyhydric alcohols such as isopropyl alcohol, 2 hydroxyhexane, 2-3 dihydroxybutane, 2-3 dihydroxypentane, 2-methyl-2-nitro-1:3-dihydroxybutane, 3-chloro-2-hydroxybutane, the secondary alcohols prepared by hydration of olefines containing up to 12 or 14 carbon atoms (from the cracking of paraffin wax) and 1-12-dihydroxyoctadecane.

Title: A method of completion cleanup involving movement of fluid from a first zone into a second zone
Inventor: PAHMIYER ROBERT C
IPC: E21B21/00
Filed: 2000-12-15
Abstract: A method of performing a well completion cleanup involves flowing completion fluid from a first zone (18) into a second zone (20). Packers (24, 28) are used to isolate a production zone (18) containing the completion fluid, which enters tubular (26) through well screen (14). The fluid is then pumped by pump (34) out of the lower end (39) of the tubular into a disposal zone (20). This allows completion fluids to be disposed of without having to be pumped to the surface. Various configurations are described, where the orientation of the zones may be reversed, where the pump (34a, fig 3) is deployed on a wireline (fig 3) and where telemetry is used to control the operation.

Title: Pigment
Inventor: BUTTLE LOUISE GEORGINA
IPC: A23K1/16
Filed: 2000-05-08
Abstract: The present invention provides a method of improving the pigmentation of fish flesh. Specifically, this is brought about through feeding the fish with both pigment and cholesterol, which are generally combined into a foodstuff. This addition of the pigments in the diet which results in a change in flesh colour, blood pigment levels and flesh pigment levels of the fish. Further, the uptake of pigment into the plasma and flesh is shown to be optimal when the feed contains a cholesterol level of between 1 and 3 percent. Such a method of enhancing the uptake of pigment by fish can be used on Atlantic salmon, rainbow trout, other salmonids, tropical fish and any other fish species where the pigment colour of either the flesh or skin is important.

Title: A resiliently clamping wrench
Inventor: DUFFEY SEAMUS
IPC: B25B13/46
Filed: 2002-10-30
Abstract: A wrench 1 is disclosed having a handle 3 , a head portion 2 for engaging a drive socket 4 to tighten or slacken a fastener such as a nut, bolt or screw, and an operative portion 9 intermediate the handle and head portion. The head portion 2 is a flexible ring 2a having a radial gap 2g therein and an arm 2c,2e extending radially outwardly from each end of the ring respectively. The arms, preferably of unequal lengths, are mounted on the operative part 9 so that when the handle 3 is rotated in a drive direction (Fig 5b, D) the head portion 2 clamps onto the drive socket 4 with increasing pressure as drive torque increases through rotation of the handle. Movement of the handle 3 in the opposite direction (Fig 5a, R) allows free rotation of the head portion 2 relative to the drive socket 4. The ring 2a is flexible so as to move towards and clamp onto socket 4 with the gap 2g closed, in an operative condition of the wrench.
