Title: Process of vapor phase catalytic hydrogenation of maleic anhydride to gamma-butyrolactone in high conversion and high selectivity using an activated catalyst
Inventor: TAYLOR PAUL D
IPC: C07D307/33
Filed: 1991-04-08
Abstract: Vapor phase catalytic hydrogenation of maleic anhydride to gamma-butyrolactone is achieved in a conversion of 95 % or more and a selectivity of 80 % or more during a prolonged period of production. The process of the invention uses an activated catalyst prepared by reducing a catalyst composition comprising 30-65 % by weight of CuO, 18-50 % by weight of ZnO and 8-22 % by weight of Al2O3, and, particularly, by activating the reduced catalyst composition in hydrogen at an activation temperature of at least 400 ·C, preferably 400 ·C to 525 ·C, and optimally about 425 ·C. The hydrogenation process is carried out under predetermined and advantageous process conditions, including a defined molar ratio of hydrogen to maleic anhydride in the vapor reactant stream, a selected pressure during hydrogenation, an advantageous feed rate space velocity, a predetermined contact time, and a suitable reaction temperature.

Filed: 1991-06-26
Abstract: The present invention refers to a process for creating in an aquifer an oxida-tion and precipitation zone (or a reduction zone) between a number of injection wells arranged around one or more extraction wells for purified water. The zone de-sired is created intermittently between each pair of adjacent injection wells by (i) in-troducing oxygen, oxygen-containing gas or an oxygen-releasing substance (or an oxygen-consuming substance) into the water in both wells and (ii) pumping the wa-ter in one well from below upwards while pumping the water in the other well from above downwards, whereby a circulation circuit is formed in the aquifer between the webs. A device for carrying out said process comprises an outer tube (1), sealing means (2), an inner tube member (3), a transversal wall (4) with a central opening, an elongation tube (5), an inner flow pipe (6) and conduits (7, 8) for supply of air.

Title: Cone Shaped Flocculation Tank
Inventor: KALLIS LYLE G
IPC: B01D21/08
Filed: 1993-07-02
Abstract: When drilling wells a drill fluid is used to lubricate the drill bit and remove the drilled out material from the bottom of the drill hole. In this invention a partly cylindrical and partly conical vertical tank, capable of being moved from site to site, permits the contaminated drill fluid to be cleaned for re-use in the drilling operation, thereby permitting less drill fluid to be used in each drilling operation. The contaminated drill fluid is introduced into the tank at its middle, through an input centrifuge pipe which enlarges and circles the inside of the tank. The centrifuge pipe has slots along its bottom. As the contaminated drill fluid is pumped into the tank the drilled out material settles out and the clear fluid rises to the top of the tank, is retrieved through the output pipe and re-used. The intake of the output pipe is directed upwards and flanged outwards to form a bowl like effect.

Abstract: ABSTRACT OF THE DISCLOSURE A coupling for connecting a movable link member of a valve actuator assembly to a movable valve spool in a fluid control valve includes a swivel spud secured to the end of the valve spool. The swivel spud has a semi-spherical outer end surface and first and second transverse apertures formed therethrough.  A first cylindrical pin is retained within the first aperture of the swivel spud.  The actuator assembly further includes a movable inner piston having an end portion, which is generally hollow and cylindrical in shape, and a pair of opposed apertures formed therethrough. The semi-spherical outer end surface of the swivel spud is received within the hollow end portion of the inner actuator piston.  A second pin is retained in the opposed apertures of the inner actuator piston, extending through the second aperture of the swivel spud.  When the inner actuator piston is moved in one direction, the pins engage one another to effect movement of the valve spool in that direction.  When the inner actuator piston is moved in an opposite direction, the semi-spherical surface of the swivel spud engages a flat reaction surface of the inner actuator piston to effect movement of the valve spool in that direction.

Title: Retractable point system for a dart
Inventor: PICKUP JEFFREY
IPC: F42B6/00
Filed: 1993-08-05
Abstract: A novel dart (10) is equipped with a dart point contraction system which allows the dart point (14) to contract into the body (11) or barrel of the dart as when the dart point (14) impacts wire, or staples and the like which surmount boundaries of denominated regions of a dartboard. The dart body (11) defines a cylindrical cavity (33) into which the downstream end of the dart point (14) can reciprocatingly travel since it also is cylindrical and comes to rest against the dart body (11) at the end of its travel. It is as a result of the kinetic energy of flight that even though the dart point (14) may have impacted a boundary wire or even a denominated region of the dartboard, that "bounce-out" is inhibited by the cylindrical portion (20) of the dart point (14) travelliing in the cylindrical cavity (33) of the dart body (11) when impact occurs.
