Patent CA-2403610-A1 (CA)
IPC: B65C9/32
Filed: 2002-09-17
Abstract: A buoyancy flushing apparatus is disclosed which comprises a reservoir for accumulating liquid, having an inlet for receiving liquid and an outlet chamber recessed in a bottom wall of the reservoir. The outlet chamber includes an outlet for draining liquid out of the reservoir. The apparatus further comprises an outlet valve movable between a down position where liquid accumulates in the reservoir and a raised position where liquid accumulated in the reservoir is flushed out via the outlet. The outlet valve comprises a bottom portion sized and shaped to fit loosely in the outlet chamber when said valve is in the down position; and a float portion topping the bottom portion to move the valve in the raised position by buoyancy when a sufficient amount of liquid is accumulated in the reservoir, thereby providing a passageway for liquid between the bottom wall of the reservoir and the valve leading to the outlet in the outlet chamber to flush liquid out of the reservoir. Guiding means are provided for guiding the outlet valve between the down position and the raised position. The apparatus can be used for applications such as water treatment and irrigation. It could advantageously be used for directing and spreading waste water previously treated in a septic tank to different sanitary treating fields.

Abstract: The invention relates to a composition and process for improving the combustion of any kind of combustible. Also the invention relates to a process and device for obtaining such composition. The variant destined to the firing installations using common liquid/gaseous combustible as well as those ones using solid combustibles and, simultaneously liquid/gaseous combustibles for enhancing the combustion contain -20% of 6% watery solution of potassium dichromate, treated with monochromatic light having /  =480-490. 10-9 m; 0.02 ammonia; 0.3%  non-additivated mineral oil and-80%  demineralized water. The variant destined to the firing installations using solid combustibles -10% of 5% watery solution of potassium permaganate, treated with monochromatic light having/=595-625.10-9 m; 0.05% urea 0.3% non-additivated mineral oil and -90%  de-mineralized water. The process for improving the combustibles combustion by using these composition consists in their introduction into either the combustion air or the mass of the combustibles. The process of treating the active substance of these compositions with monochromatic light consists in that the active sustance draining with constant discharge along a collector trough (1") is allowed to freely drop along the superior generating line of quartz glass cylinder (2"), in uniform rotation with 10-12 rot/min, axially illuminated by a monochromatic light generator of 20w power and 40mVV/cm2light density. A monochromatic light generator (4") with a colour filter (7") is placed at one end of the cylinder (2") so the light is emitted along the cylinder rotation axis, and at the other end a plane mirror (5") is placed so the light of generator (4") is reflected; a collecting vessel (6") is disposed under the glass cylinder (2") in order to collect the treated liquid flowing along the cylinder (2").
