Title: An isolation valve manifold
Filed: 2008-02-14
Abstract: An isolation valve manifold 12 body has an inlet 21 and an outlet 22, an outlet bleed port 27 and first and second first and second valve cavities 25, 26. The first valve cavity 25 receives a first isolation valve 13 and defines a first isolation valve chamber. The second valve cavity 26 receives a bleed valve 15 and defines a bleed valve chamber that forms part of the fluid path. The first and second valve cavities 25, 26 are angularly offset and arranged such that the bleed valve and isolation valve chambers intersect one another so as to define a first opening 36 that provides fluid communication between the bleed valve chamber and the isolation valve chamber. This eliminates the need for cross-drillings between the valve chambers and provides a compact arrangement in which the valves can be operated easily without mutual interference.

Title: Nitric acid esters
IPC: C07C203/02
Filed: 1984-06-04
Abstract: The invention concerns a process for the preparation of nitric acid esters of organic hydroxy compounds by reacting an organic hydroxy compound with nitric acid in the presence of sulphuric acid and in a solvent, followed by separating off the spent acid, substantially neutralizing the residual acidity of the organic solution, and removing solvent to leave the organic nitrate. From 95% to 220% of the stoichiometric requirement of nitric acid for complete nitration is used. The mole ratio of water to sulphuric acid at the end of the reaction is from 0,2:1 to 2,5:1. From 200 to 2000 ml of solvent per mole of hydroxy group is present. Yields of at least 92% are obtained. The invention is particularly suitable for the preparation of alkyl nitrates, alkylene or polyalkylene glycol, monoalkyl ether mononitrates, alkylene or polyalkylene glycol dinitrates, diol nitrates, nitrates containing homocyclic or heterocyclic rings, or nitrates derived from polyols.

Title: Connection element
Inventor: SPAETH WERNER F
IPC: F16B7/04
Filed: 1993-06-05
Abstract: The invention concerns a connection element designed to connect two structural components, in particular a support girder and a frame girder, so that they can be detached again. The connection element is designed to be inserted in the hollow-section frame girder so that it remains fixed in place. It has at least one movable securing element which is disposed in a housing and which can be displaced in the direction of the longitudinal axis of the connection element by means of an eccentric pin which is rotatably mounted in an aperture in the housing and which passes through the securing element, thus bringing a coupling hook forming part of the securing element and projecting out of the end of the housing into engagement with a longitudinal groove undercut in the support girder. The eccentric pin is designed to be pushed into the housing against the force of a spring and locked in a cross-bore in the frame girder. In order to ensure that the securing element operates faultlessly in any position, the invention calls for the floor of the housing to have a recess which is disposed eccentrically with respect to the mounting aperture and with which a cam disc on the eccentric pin is brought into engagement at least when the securing element is in its extended position.
