Abstract: The invention provides an uncomplicated ball check valve whose components can be economically manufactured, assembled and connected and wherein, in accordance with one aspect of the invention, the ball check valve is configured for use as a pressure vessel. In one embodiment of the invention, the ball check valve comprises a housing defining one or more inlet, an outlet and a passageway therebetween. A ball support system is mounted within the housing, wherein one or more balls are supported by the ball support system. The ball support system is configured to allow a ball to close off and open a respective inlet. The housing generally comprises an inlet section which can have one or more inlets, wherein each inlet defines a ball seat sealingly engageable with a ball for sealing the inlet. The housing further comprises a centre section providing adequate space to allow movement of the ball and an outlet section comprising an outlet for transferring the fluid to a subsequent portion of a piping network.

Abstract: A system for electronically controlled generation of oxygen and hydrogen gas from an electrolyte. Ambient air is drawn into the system through the air filter and into the inlet hose. The flow of air is caused by the venturi effect of engine intake air passing over the base of the 90 degree induction fitting. The flow of air across the air flow sensor causes the controller to direct power to the chamber power lugs. At the same time, the controller monitors the level of electrolyte in the chamber case. Should the level of electrolyte drop below the upper edge of the process plates, the controller will then cause power to be directed to the reservoir pump to restore electrolyte fluid to a predefined level. In addition to monitoring electrolytic solution level, the controller monitors voltage and amperage across the two chamber power lugs, and the temperature of the electrolytic solution in the process chamber case. This information is stored in the controller and displayed when requested.

Abstract: A scaffolding system for use on an inclined surface, such as inside a ship cargo hold. The scaffolding system includes a scaffold pole and a support bracket that secures the scaffold pole to a support surface. The support bracket is only in place temporarily and is removed once the work is finished. A swivel foot is coupled to the scaffold pole. The swivel foot is configured to pivotally align with the inclined surface. A preventer is attached to the scaffold pole, and uses the support surface to prevent the scaffold pole from sliding along the inclined surface, and to provide additional lateral support.
