Patent CA-2082096-A1 (CA)
Inventor: GARKAWE MICHAEL
IPC: B04C5/08
Filed: 1992-11-04
Abstract: WATER-COOLED CYCLONE SEPARATOR               Abstract of the Disclosure A cyclone separator formed by a plurality of parallel tubes and a plurality of fins.  Each tube is configured in a multitude of segments.  one segment of the tubes forms a cylindrical section, one segment is bent inwardly to form a roof section, and one segment is bent inwardly to form a conically-shaped hopper section.  As the circumference and diameter of the hopper section decreases from top to bottom, at least a portion of the tubes are configured, either by being extracted or swaged, to accommodate the decreasing circumference and diameter, which results in an increase in the heat recovery of the water-cooled heat transfer tubes without the need for an intermediate ring header.     2d/0895I

Title: Underground fluid sampling system
Inventor: CORDRY KENT E
IPC: E21B43/12
Filed: 1991-05-10
Abstract: A system (10) and method for implanting an underground device.  The system (10) includes a hollow body (12) for containing said underground device and a drive cone (22) adapted to penetrate the ground. The drive cone (22) is removably attached to the hollow body (12) so that once the system (10) is driven into the ground to a desired depth, the hollow body (12) may be pulled upward slightly to cause the drive cone (22) to be removed. This permits underground fluids to enter the hollow body (12) and the underground device. The system provides a durable and inexpensive means for sampling fluids from a desired depth without requiring the drilling of a well.

Title: Apparatus for controlling lateral movement of vehicle bodies
Inventor: ALLEN DAVID H
IPC: B61F5/24
Filed: 1992-05-21
Abstract: A railway vehicle has a passenger carrying body (10) mounted on a bogie comprising a frame (12) and wheelsets (14). To accommodate lateral movement of the body (10) relative to the bogie frame (12), subsequent to the movement accommodated by conventional shear rubber mounts (16), a bump stop arrangement is provided towards each end of the vehicle. Each arrangement is mounted on a body part and has a pair of piston and cylinder assemblies providing rubber abutments (18) towards respective sides of the body part for engagement with the bogie frame (12). The spaces in each cylinder (24) on respective sides of the piston (22) communicate with respective fluid accumulators (28, 30), a valve controller (32) monitoring lateral movement of the vehicle body (10), and controlling movement of fluid supply between the cylinders and the accumulators. Movement of a respective abutment (18) into contact with the bogie frame (12) only when necessary, and subsequent continuous adjustment of the resistance provided by the abutment (18), prevents significant increase in the dynamic stiffness of the bump stop arrangement and mitigates unwelcome impact between the body (10) and the bogie frame (12), resulting in a relatively smoother ride for passengers.

Title: Method for the manufacture of tall oils
Inventor: HUIBERS DERK T A
IPC: C25B3/00
Filed: 1992-08-03
Abstract: The present invention relates to the direct electrolysis of tall oil soap (TOS) to produce crude tall oil (CTO). An aqueous tall oil soap solution (22) generated in a kraft wood-pulping process is placed in contact with an anode (34) in an electrolytic cell, wherein the tall oil soap is disassociated to form crude tall oil and free sodium ions. The sodium ions migrate through a membrane (36) to associate with hydroxide ions formed in a cathode chamber (38) to form NaOH, which may optionally be recycled to the kraft pulping process as a make-up chemical for lost sodium. The crude tall oil is recovered from the electrolyzed tall oil solution for further refinement. Optionally, the tall oil soap solution is treated prior to electrolysis to remove components which may interfere with the electrolysis.
