Patent CA-2268943-A1 (CA)
Inventor: LYNCH DAVID MATTHEW
IPC: B23K11/06
Filed: 1997-12-08
Abstract: Resistance welds on overlapped sheets of metal, such as the welded side seam of 3 piece cans, are monitored by measuring the width of the extrusion (5, 6) formed by material flowing out from the edge of the overlapped sheets (1, 2) caused by the welding process. The width of the extrusion (5, 6) is interpreted in terms of the temperature of the weld, and the welding process can be adjusted accordingly. The measurement of the extrusion width can be done optically.

Abstract: S-nitrosohemoglobin (SNO-Hb) can be formed by reaction of Hb with Snitrosothiol and by other methods described herein which do not result in oxidation of the heme Fe. Other methods can be used which are not specific only for thiol groups, but which nitrosate Hb more extensively, and may produce polynitrosated metHb as a product or intermediate product of the method. SNO-Hb in its various forms and combinations thereof (oxy, deoxy, met; specifically S-nitrosylated, or nitrosated or nitrated to various extents) can be administered to an animal or human where it is desired to oxygenate, to scavenge free radicals, or to release NO+ groups to tissues. Thiols and/or NO donating agents can also be administered to enhance the transfer of NO+ groups. Examples of conditions to be treated by SNO-Hbs or other nitrosated or nitrated forms of Hb include ischemic injury, hypertension, angina, reperfusion injury and inflammation, and disorders characterized by thrombosis. Further embodiments of the invention are methods for assessing oxygen delivery to the tissues of a mammal by measuring SNO-Hb and nitrosylhemoglobin in blood.

Abstract: An automatic pipe handling system for automatically transporting pipe sections to and from a horizontal boring machine. The system comprises a pipe handling assembly, a pipe lubrication assembly, a makeup/breakout assembly, and an automatic control system. The pipe handling assembly stores pipe sections and transports the pipe sections to and from the drill string of a boring machine. As the pipe handling assembly transports a pipe section, the pipe lubrication assembly lubricates the appropriate pipe joints. The makeup/breakout assembly secures the drill string and pipe joints so that pipe sections can be added to or removed from the drill string. A programmed controller automatically operates the pipe handling system and its components by synchronizing the operations of the pipe handling system. The controller sequences and times the operation of each aspect of the pipe handling system during both the boring operation and the backreaming operation.

Abstract: The invention relates to a method for the production of a transverse fibre web (10). The fibres in the fibre layer of the transverse fibre web are substantially parallel to one another, the direction of the fibres forming an angle with the longitudinal direction of the transverse fibre web. The transverse fibre web is produced by cutting web parts (9) from a longitudinal fibre web (1), the longitudinal sides of which web parts are attached to one another. The longitudinal sides are substantially parallel to the fibres. The longitudinal fibre web is produced by applying a fibre layer to a base stabilizing layer, which fibre layer is inseparably connected to the base stabilizing layer. A film, a fibre fabric or a thermosetting material may be selected for the base stabilizing layer. The material for the base stabilizing layer is selected in such a way that when the web parts are attached to one another so as to form a transverse fibre web the base stabilizing layer can take up tensile forces in the longitudinal direction of the transverse fibre web.

Title: Swing control for altering power to drive motor after each swing cycle
Inventor: ALLISON TRUMAN L
IPC: A63G9/16
Filed: 1999-12-17
Abstract: A control (200a) for an infant and child swing (40) driven by a direct current motor (160) includes a user interface (312) for selecting from a plurality of swing heights (or amplitudes), a microcontroller (400) having a processor (401), a swing angle indicator (118) having a light interrupter detector (210), and a music system (410). Processor (401) receives an output signal from light interrupter detector (210) for monitoring the current swing amplitude. At the end of each swing cycle processor (401) compares the current swing amplitude with the user selected maximum swing amplitude, and, if not substantially equal, generates a control signal to adjust the power output from motor (160) so that the current swing amplitude substantially equals the user selected maximum swing amplitude. This cycle-by-cycle adjustment produces a swing arc having improved accuracy and consistency. Processor (401) also ends operation of motor (160) after an optional, user preselected, fixed time period, and facilitates maintenance and repair by displaying the status of light interrupter detector (210) upon selected actuation of user interface (312).

Title: Mixing apparatus
Inventor: CLARKE NEVILLE
IPC: B01D17/035
Filed: 1998-08-27
Abstract: A method and apparatus for mixing a first material and a second material is described in which the first material comprises a mixture of two or more dissimilar components which it is desired to separate. The method and apparatus involve forming an intimate mixture of the two materials prior to separating the two dissimilar components of the first material. The apparatus involves the use of a hydrocyclone for aerating or gasifying a feed stream, such as waste water containing oleophilic residue or food residue, to entrain the particles of residue within the air or gas bubbles prior to separating the oil or food residues from the carrier material, typically water. Instead of using the hydrocyclone as a separator, it is used as a mixer which provides surprising results and facilitates separation of the aerated components.
