Patent CA-2316901-A1 (CA)
Title: Electrolytic process for treating aqueous waste streams
Inventor: JACKSON JOHN R
IPC: B01D53/14
Filed: 1998-12-17
Abstract: An electrochemical process for the production of a hydroxide solution and a sulfate by the electrolysis of a waste aqueous mixture of oxidizable sulfur impurities in the anode compartment of at least one electrolytic cell while producing a hydroxide solution in the cathode compartment of the cell. The process is particularly applicable to the treatment of spent caustic solutions obtained by scrubbing a hydrocarbon process stream contaminated with oxidizable sulfur impurities.  The electrolytic cell used in the electrolysis process of the invention can use either a porous membrane or a cationic permselective membrane to separate the anode and cathode compartments of the electrolysis cell. The electrolysis cell can be monopolar or bipolar and when bipolar, the bipolar electrodes if dissimilar, or the respective anode and cathode current collectors if dissimilar, which are attached thereto, are electrically connected by bonding with a conductive polymer or are joined by welding with or without an intermediate metal layer therebetween. Control of pH in the anolyte compartment of the electrolytic cell can be achieved by passing a selected amount of catholyte to the anolyte compartment. Pre-treatment with oxygen produced in the anolyte compartment of the cell avoids release of gaseous products from the anolyte compartment and increases process efficiency. Where the process is conducted in multiple electrolytic cells, such cells are hydraulically connected in series in a cascading series.

Patent CA-2340006-A1 (CA)
Inventor: HATTLER BRACK G
IPC: A61M1/16
Filed: 1998-08-11
Abstract: A percutaneous oxygenator is used to induce a retrograde perfusion of oxygenated blood in a vein to a compromised organ (e.g., to the brain following a stroke, or to the heart following a heart attack). The oxygenator (10) has an occluding balloon (25) and an oxygenation balloon (20) located upstream from the occluding balloon (25). A plurality of hollow gas-permeable fibers (14) surrounds the oxygenation balloon (20). The oxygenator (10) is inserted into a vein (84) downstream from the compromised organ. An external supply of air/oxygen is connected to create a flow through the fibers (14) and thereby oxygenate blood in the surrounding vein. A retrograde flow of oxygenated blood is induced in the vein to the compromised organ by first inflating the occluding balloon (25) to occlude the vein and then inflating the oxygenation balloon (20). Both balloons (25, 20) are then deflated to permit the normal antegrade flow of blood through the vein. This process of inflation and deflation is periodically repeated at a rate of about 30 to 60 cycles per minute. The percutaneous oxygenator (10) may be equipped with multiple occluding balloons for blocking several branches of the venous system leading from the compromised organ.

Abstract: A system and method for configuring an air interface processor in a modem. The air interface processor includes an event handler and a microsequencer. The event handler schedules data for transmission and reception in the modem. For transmission, the microsequencer sends commands to a frame formatter to format the data to be transmitted based on the schedule. Similarly for reception of data, microsequencer sends commands to a frame deformatter to deformat received data based on the schedule. The event handler, microsequener, frame formatter and deformatter are programmable or configurable to accommodate different transmission formats and standards. A multi-way branching instruction is used in the programming of the microsequencer to enable faster processing.

Title: Improvements in marine anchors
Inventor: BRUCE PETER
IPC: B63B21/40
Filed: 1999-10-29
Abstract: A marine anchoring arrangement is described wherein a marine anchor (1, 23) is drivingly embedded vertically into a mooring bed (10) by an elongate follower (13), especially by its own weight and that of the follower. The follower (13) has a bottom clevis part (103) adapted to hold detachably the anchor (1) via the anchor shank (2) by means of a fulcrum pin (17) whereby the anchor (1) may swing relative to the bottom part (103). For initial penetration. the anchor (1) is held in a position of minimum forward resistance, specifically with the forward direction F of the fluke (3) parallel to the follower axis (20) and this is achieved by a shear pin (109) between the anchor (1) and the bottom part (103). When the anchor (1) is embedded to a preferred depth (d) specifically at least twice the square root of the maximum projected fluke area (as viewed normal to direction F), the anchor (23) is moved to a position for anchor setting by pulling on an attached anchor cable (4/4A) so causing the shear pin (109) to fracture and the anchor (23) to rotate about the fulcrum axis until arrested by a stop (21) on the follower (13). The follower (13) can then be pulled clear and recovered. The above anchoring arrangement provides a considerably improved anchoring performance in comparison with existing direct embedment arrangements.

Abstract: A stuffing box and a method of sealing the same involves positioning a sealing assembly in the stuffing box which includes a first annular seal carrier and a second annular seal carrier. Each of the first annular seal carrier and the second annular seal carrier has an interior shaft engaging surface with at least one seal and an exterior housing engaging surface with at least one seal. Packing is disposed between the first annular seal carrier and the second annular seal carrier.      A second step involves injecting a viscous lubricant into the packing. The role of the first annular seal carrier and the second annular seal carrier is containment of the viscous lubricant. The presence of this viscous lubricant helps preclude the incursion of produced well fluids into the sealing assembly, as the produced well fluids cannot enter into the sealing assembly without first displacing the viscous lubricant.

Title: Simultaneous slicing and washing of vegetables
Inventor: BROWN DANIEL E
IPC: A23L19/18
Filed: 2001-07-26
Abstract: Simultaneous slicing and washing of relatively firm raw vegetable or fruit products is accomplished in a vat of water into which a slicer apparatus is positioned such that the slices are formed and discharge directly into the water An inclined takeout conveyor serves to receive the slices and remove them from the water. A circulating water current and fluid jets urge the slices to disperse onto the conveyor. A spray of water or air blast removes residual vegetable matter from the slice surfaces before leaving the takeout conveyor for further processing. Slicing and washing a vegetable in a flume volute where the slices are dispersed onto a takeout conveyor is disclosed where the water medium is collected in a tub and recycled back to flow in the flume to a level that covers the slicer's operative parts. The apparatus may be used for simultaneous slicing and cooking of raw vegetables where hot cooking oil is maintained in the system and recycled for reheating.
