Title: Process for the production of purified terephthalic acid
Inventor: TURNER JOHN A
IPC: C07C51/43
Filed: 1993-05-19
Abstract: A process for the production of purified terephthalic acid comprises subjecting an aqueous solution of crude terephthalic acid to hydrogenation to reduce impurities therein, crystallising the resulting solution to produce a slurry of purified terephthalic acid in aqueous liquor and carrying out an integrated terephthalic acid separation and washing process without a reslurrying stage between separation and washing. In one form of the invention, the integrated separation and washing process is implemented at elevated pressure by means of a belt filtration system (100, Figure 2) in which the pressure on the downstream side of the filter belt is no less than that prevailing following pressure let-down in the crystallisation process. Other implementations of the invention may be achieved by means of centrifuge apparatus incorporated arrangements for the application of wash liquor to the cake formed during centrifuging (Figures 3 and 4).

Title: Oil and gas well cuttings disposal system
Inventor: DIETZEN GARY H
IPC: E21B21/06
Filed: 1995-02-15
Abstract: A method of removing drill cuttings from an oil and gas well drilling platform includes the steps of separating the drill cuttings from the well drilling fluid on the drilling platform so that the drilling fluids can be recycled into the well bore during drilling operations.      The cuttings are transmitted via gravity flow to a materials trough having an interior defined by sidewalls and a bottom portion. The drill cuttings are suctioned from the bottom portion of the trough interior with a first suction line having an intake portion that is positioned at the materials trough bottom. Drill cuttings are transmitted via the suction line at flow velocities in excess of 100 feet per second to a holding tank that has an access opening. A vacuum is formed within the holding tank interior using a blower that is in fluid communication with the tank interior via a second vacuum line. Liquids and solids flowing in the vacuum lines are separated from the vacuum lines before the liquids and solids can enter the blower. The blower is powered with an electric motor and the tank interior is sealed after being filled with drill cuttings to be disposed of. The tank is configured to be emptied via gravity flow at a remote disposal site by opening the access openings and allowing the cuttings to flow via gravity from the tank interior access openings.

Filed: 1994-03-25
Abstract: An image processing system containing apparatus and a concomitant method for rapid image processing using a computer system. The system generates a special image format containing a plurality of subimages. When an image is edited, the system uses the information in the subimages to calculate a good depiction of the image on the display at the display resolution given the current pan and zoom. Image alterations are stored within a computer file as an expression tree. Each node in the expression tree defines a particular editing operation that resulted in modifications to the image. To display the image upon a computer monitor display, the expression tree defining the alterations is evaluated to form a composite output image having any resolution necessary to display an accurate rendition of the edited image. Once edited, the output image can be printed on a high resolution printer by combining expression tree with a full resolution image to produce a high resolution output image.

Title: Apparatus for the continuous production of a particulate filled barrier
Inventor: TAYLOR EDGAR J JR
IPC: B65B9/06
Filed: 1995-09-26
Abstract: An apparatus for continuously producing a particulate filled bag or barrier.  The apparatus includes a frame having terrain engaging members, such as runners.  A wound coil of sheet material is mounted on the forward end of the frame, and located to the rear of the coil is an open bottom hopper that contains a partic-ulate material, such as sand or gravel.  The sides of the hopper are composed of spaced double walls and the rear surface of the hopper is formed with an outlet.  The sheet material is unwound from the coil and continuously folded into a generally U-shape by a pair of lower roll-ers and two pair of upper rollers, which are mounted on the frame forwardly of the hopper.  The bottom surface of the folded sheet extends across the open bottom of the hopper, so that the particulate material will be in direct contact with the bottom surface, while the side surfaces of the folded sheet extend upwardly in the spaces between the double side walls of the hopper.  The weight of the particulate material resting on the bottom surface of the folded sheet will hold the sheet against the terrain as the frame is moved forwardly, and the folded sheet containing the particulate material is discharged from the outlet in the hopper and passes between a pair of converging side members to compress the particulate material.  The upper edges of the side sur-faces of the folded sheet are then brought together and connected to provide a bag containing the particulate material.

Inventor: HENSLEY JERRY C
IPC: B23Q1/00
Filed: 1995-11-15
Abstract: A coolant delivery method and apparatus comprising a high and low pressure pump for providing high and low pressure coolant flow through a common conduit to a coolant orifice of a cutting tool of a machine tool or a nozzle of a workpiece flushing station. The high pressure pump has a cylinder with a reciprocable piston operably coupled to a drive for moving the piston to discharge coolant under high pressure to the cutting tool while a workpiece is machined by the tool. A one-way flow valve in the conduit permits coolant flow from the low pressure pump to reach the cutting tool as well as the high pressure pump cylinder to recharge the cylinder with coolant while the high pressure pump is not discharging coolant.  Cutting tool failure as well as  an orifice obstruction is detected by monitoring coolant flow from the high pressure pump during each machining cycle of machine tool operation. A signal is generated if high pressure coolant flow to the cutting tool during a machining cycle is not about the same as coolant flow during a calibration machining cycle where there is no cutting tool failure nor cutting tool orifice obstruction.

Title: Compositions and methods for treating cancer and hyperproliferative disorders
Inventor: NACY CAROL A
IPC: A61K38/18
Filed: 1994-05-26
Abstract: The present invention encompasses methods for reducing or inhibiting growth factor in cancer cells and tissues. More particularly immunogenic growth factor-containing compositions are administered to a human or animal with a cancer or tumor. The immunogenic compositions elicit the production of antibodies specific for growth factor which reduce the level or circulating growth factor, thus reducing or eliminating the proliferation of cancer. The present invention encompasses growth factor-containing liposomes and vesicles having portions of growth factor externally presented on their surfaces. The present invention alsoincludes antibodies specific for growth factor. Thus, according to the present invention, growth factor levels are reduced either by active immunization of an individual using immunogenic growth factor-containing compositions or by passiveimmunization via administering to the individual an antibody or a group of antibodies specific for growth factor.
