Patent CA-2179902-A1 (CA)
Inventor: FORTUNKO CHRISTOPHER M
IPC: G01N29/07
Filed: 1995-10-26
Abstract: A new ultrasonic method for measuring wall thickness and detecting material flaws in natural-gas pipelines (30), risers, and similar structures. The method is inherently suitable for the task, because it relies on the use of the natural gas (G) as the coupling fluid for transmitting the probing ultrasonic signals into and out of the pipe wall. Furthermore, the method facilitates the operation of the inspecting from the inside of the pipe (30). An experimental apparatus is also described. Significantly, it is shown that by the use of a diplexer (18), the same transducer (15) can be used to generate and detect the probing ultrasonic signals. The same configuration is used in commercial ultrasonic inspecting of oil pipelines where oil is the coupling fluid; but until now this method could not be used in natural gas pipelines due to the low specific acoustic impedance of natural gas.

Abstract: An automatically retractable step assembly for watercraft rotatably mounts to a fixed step assembly fixed to the craft, a movable sliding chassis mounted on tracks, or a manually retractable step. The automatically retractable step assembly can also rotatably mount to another automatically retractable step assembly. The automatically retractable step assembly is preferably formed by a U-shaped member with outward projections that rotatably fit over mating projections from a supporting element. The U-shaped member is biased by torsion springs to rotate with respect to the supporting elements towards a position in which the retractable step assembly will be stored and away from the water. The retractable step assembly, during use, is rotatable against the bias and towards or into the water by pulling or stepping on the retractable step. The step also has a quick-disconnect mechanism to simplify maintenance.

Abstract: This invention discloses an apparatus for introducing a free-flowing balancing material into a tire through a tire valve stem. The apparatus comprises a container for confining a predefined amount of free-flowing balancing material, and a flow path for pressurized air which extends from the source of the pressurized air to an air inlet, from the air inlet to a mixing chamber in communication with the container through an opening, and from the mixing chamber to an air outlet. The flow path has a pressure regulator therein, a venturi nozzle within the mixing chamber to accelerate the air flow and lower the air pressure within the mixing chamber to draw the free-flowing balancing material from the container into the mixing chamber; and a chuck for introducing the mixture of free-flowing balancing material and pressurized air from the air outlet and into a tire valve stem. The volume of the container is large enough to contain an amount of free-flowing balancing material sufficient to effect dynamic balancing of a tire and associated wheel assembly.

Abstract: A water-disintegrable sheet having biodegradability. The sheet comprises one or more kinds of biodegradable synthetic fibers, and one or more kinds of natural fibers and/or regenerated fibers, all the fibers being bound together by a binder such that the binding power of the binder will be substantially lost in water. The sheet has a given degree of tensile strength and good softness, coupled with a required degree of liquid absorbency, and still has some biodegradation property. Therefore, the sheet can be flushed in a flush toilet without involving any appreciable increase in the volume of solid residues in a septic tank and/or in a sewage disposal plant and is therefore suitable for use in the form of a wet wiper in particular.
