Patent ZA-848299-B (ZA)
Title: A load control system
Inventor: BARKER GARY THOMPSON
IPC: F15B11/02
Filed: 1984-10-24
Abstract: A load control system is disclosed for preventing the uncontrolled lowering of a load should a line failure occur in a hydraulic system. The system is designed to be used with a hydraulic cylinder having a movable piston therein which divides the cylinder into a head end and a rod end. Attached to the piston and extending out of the hydraulic cylinder is a piston rod which has a load secured to its free end. The load control system includes a source of pressurized fluid, the flow of which is selectively controlled to the hydraulic cylinder by a control valve. Positioned between the control valve and the head and rod ends of the hydraulic cylinder, respectively, are first and second valves each of which is normally biased towards a closed position by a common pressure. The first and second valves are urged toward an open position by fluid pressure taken between the control valve and the first valve and are movable by this fluid pressure in a proportional manner with the second valve being opened first. The second valve is also physically mounted directly to the hydraulic cylinder such that if a line breakage occurs, the load will still be unable to drop.

Inventor: SWINTON PETER FRANCIS
IPC: C01B21/20
Filed: 1994-05-17
Granted: 1997-08-27
Abstract: A process for the production of dinitrogen pentoxide (N2O5) in an organic solvent consists of dividing off a minor proportion (31) of the anolyte stream (11) of an electrolytic cell (2) which is set up to generate N2O5 and of cooling that portion and/or adding to the portion a quantity of N2O4, such that two phases are formed. The phases are separated (34) and the light (upper) N2O4 phase is then stripped of dissolved N2O5 the N2O5 being redissolved in an organic solvent. Conveniently, the N2O4 phase is chilled (at 41) to produce crystalline N2O5 which is dissolved in an organic solvent such as dichloromethane. All effluent streams may be recycled with addition only of fresh concentrated nitric acid and fresh N2O4 to make the process capable of continuous operation. <IMAGE>

Title: Diazonaphthoquinonesulfonyl substituted polymers
Inventor: HONG SUNG-EUN
IPC: C08F8/34
Filed: 1999-07-23
Granted: 2003-03-26
Abstract: The present invention relates to organic anti-reflective coating polymers and preparation methods therefor. Anti-reflective coatings are used in a semiconductor device during photolithography processes to prevent the reflection of light from lower layers of the device, or resulting from changes in the thickness of the photoresist layer, and to eliminate the standing wave effect when ArF light is used. The present invention also relates to anti-reflective compositions and coatings containing these organic anti-reflective coating polymers, alone or in combination with certain light-absorbing compounds, and preparation methods therefor. When the polymers of the present invention are used in an anti-reflective coating in a photolithography process for forming submicro-patterns, the resultant elimination of changes in CD due to diffractive and reflective lights originating from lower layers increases the product yield in the formation of submicro-patterns during the manufacture of 64 M, 256 M, 1 G, 4 G and 16 G DRAM semiconductor devices.
