Title: Direct-to-press imaging system for use in lithographic printing
Inventor: FADNER THOMAS A
IPC: B41F7/02
Filed: 1992-07-07
Abstract: A direct-to-press imaging system for use in lithographic printing wherein a master-image printing cylinder (10) is used with separate application of ink and water onto its surface to enable repetitive conveyance of image-formatted ink films onto substrates for printing purposes. The imaging system includes a master-image printing cylinder (10) adapted for receiving a hydrophilic coating layer (26) on its surface and a device (30,32) for laying down a uniform layer of hydrophilic material (22) on the surface of this cylinder. An apparatus (35,80,88) is also provided for applying oleophilic materials (34) in image-formatted patterns on top of the layer (26) of hydrophilic material on the master-image printing cylinder (10) to form a printing structure having separate hydrophilic and oleophilic areas of the format to be printed. Further, a mechanism (44,46) is provided for removing the printing structure including both the hydrophilic (22) and oleophilic materials (34) from the surface of the master-image printing cylinder (10) so that a new printing structure corresponding to a new image to be printed can be formed on the master-image printing cylinder (10). <IMAGE>

Title: Oil/gas separator for installation at burning wells
Inventor: ALONSO CAROL T
IPC: B01D19/00
Filed: 1992-08-27
Abstract: OIL/GAS SEPARATOR FOR                INSTALLATION AT BURNING WELLS                 ABSTRACT OF THE DISCLOSURE An oil/gas separator is disclosed that can be utilized to return the burning wells in Kuwait to production. Advantageously, a crane is used to install the separator at a safe distance from the well. The gas from the well isburned off at the site, and the oil is immediately pumped into Kuwait's oil gathering system. Diverters inside the separator prevent the oil jet coming out of the well from reaching the top vents where the gas is burned. The oil falls back down, and is pumped from an annular oil catcher at the bottom of the separator, or from the concrete cellar surrounding the well.

Title: System and method for flow control for high watercut oil production
Inventor: KOLPAK MIROSLAV M
IPC: G01F15/08
Filed: 1992-09-11
Abstract: DP 50-6-1260A ABSTRACT OF THE DISCLOSURE Net oil production from a low volume high watercut well or other source of a water-oil mixture is accurately metered with systems which include a separator vessel which allows a water-oil mixture to collect and form a separate oil layer on top of the water and which has liquid level sensors and an oil detector which measures the presence of an oil layer. The sensors are arranged in such a way with associated control circuits so that the vessel does not discharge oil until a significant accumulation of an oil layer occurs in the vessel. The systems each include a liquid discharge conduit and a motor operated control valve connected to a logic circuit which receives signals from the level sensors and the oil detector to provide cyclic operation of the valve to discharge water from the vessel repeatedly until a relatively large quantity of oil collects and then discharges all of the oil prior to resumption of the operating cycle.

Patent CA-2097230-A1 (CA)
Inventor: ALUR RAJEEV
IPC: G05B19/02
Filed: 1993-05-28
Abstract: Apparatus for developing and verifying systems. The disclosed apparatus employs a computationally-tractable technique for verifying whether a system made up of a set of processes, each of which has at least one delay constraint associated with it, satisfies a given temporal property. The technique deals with the verification as a language inclusion problem, i.e., it represents both the set of processes and the temporal property as automata and determines whether there is a restriction of the set of processes such that the language of the automaton representing the restricted set of processes is included in the language of the automaton representing the temporal property. The technique is computationally tractable because it deals with the problem iteratively: it tests whether a current restriction of the set of processes is included, and if not, it employs a counter-example for the inclusion to either determine that the delay constraints render satisfaction of the given temporal property or to derive a new restriction of the set of processes. Further included in the disclosure are techniques for checking the timing consistency of the counter-example with respect to a delay constraint and techniques for finding the optimal delay constraint.
