Title: Container for liquid having a neck with an annular seat sealed by a removable ball
Inventor: WOODRUFF JAMES M
IPC: B65D47/40
Filed: 1993-05-19
Abstract: ABSTRACT OF THE DISCLOSURE      A method of reducing spillage when pouring liquid out of a container which includes the following steps.  Firstly, place a free floating buoyant member into a resilient deformable container adapted for containing liquid.  The liquid must be of greater density than the density of the member such that the member floats upon the surface of the liquid.  The container has a fluid flow passage narrower than the dimensions of the member such that the member is prevented from exiting through the fluid flow passage.  Secondly, exert a force to temporarily deform the container thereby reducing the volume of the inner cavity and causing the liquid in the container to press the member  into  a  position  sealing  the  fluid  flow passage. Thirdly, invert the container thereby placing the container into a pouring position.  Fourthly, release the force upon the container such that the container resiliently resumes its original shape thereby increasing the volume of the inner cavity and permitting the member to float away from the fluid flow passage such that liquid freely passes through the fluid flow passage.

Patent CA-2099747-A1 (CA)
Inventor: LANDSBERGER SAMUEL E
IPC: E03B3/04
Filed: 1993-06-29
Abstract: A method and apparatus for eliminating zebra mussel colonizations from fresh water intake pipes for facilities, such as power plants and water treatment plants, are disclosed.  One or more small diameter alternate intake pipes are disposed within a main intake pipe, and the pipes are connected by means of individually controllable valves to a pump for supplying water to the facility.  Zebra mussel build up along the interior walls of any of the pipes is eliminated by shutting off flow in any mussel infested pipes with the valves, which causes starvation of the mussels due to suffocation.  When water flow is resumed, the dead mussels are easily washed out of the pipes.  The alternate intake pipes can be made of inexpensive flexible material, such as rubber, since they are not exposed to the environment external to the main intake pipe.  In addition, a non-stick coating, such as silicone, can be disposed on the interior walls of the alternate pipes to further prevent mussel build up.  A number of techniques for installing the one or more alternate pipes within an existing pipe are also disclosed.

Patent CA-2101358-A1 (CA)
Inventor: DAMRAU WAYNE A
IPC: B05D1/26
Filed: 1993-07-27
Abstract: A fountain applicator for applying coating liquid onto a web of paper carried past the applicator, has a coating liquid flow path that includes a curved surface along which a sheet of the coating liquid is flowed to subject the sheet to centrifugal force to cause air entrained in the coating liquid to move toward one side of the sheet away from the curved surface. After being flowed along the curved surface, the sheet of coating liquid is directed toward the web in a free standing jet curtain of coating liquid, to contact an opposite relatively air-free side of the coating liquid sheet against the web surface while the one side of the sheet is out of substantial contact with the web surface. Contacting the web with coating liquid that is relatively free of entrained air minimizes the occurrence of skip coating on the web, especially when the web is travelling past the applicator at high speeds.

Title: Flow regulator adaptable for use with exhaust from a process chamber
Inventor: PALMER DAVID
IPC: F24F11/04
Filed: 1992-03-13
Abstract: To control the flow of air from a process chamber, such as a clean roam, to an exhaust, a movably mounted piston (5) that is attached to a movably mounted gate (96, 961) is disposed adjacent to the flow, so that the flow passes immediately over the frontal face (52) of the piston. The distal face (51) of the piston is exposed to a reference pressure, preferably the pressure of the process chamber. The gate is mounted so as to variably impede the flow downstream of the frontal face of the piston. A restoring force, preferably the weight of the piston and the gate, tends to move the piston so as to lessen the gate's impedance on the flow.
