Patent CA-1329730-C (CA)
Inventor: OKLEJAS ROBERT A
IPC: F04D15/00
Filed: 1989-02-24
Granted: 1994-05-24
Abstract: ABSTRACT: The invention is directed to an energy recovery pump turbine for use in industrial processes where a fluid is pumped at a high pressure to the process and at least a portion of the fluid is discharged from the process at a high pressure. A turbine is positioned to receive the high pressure discharge from the process. The turbine has an impeller positioned on a shaft and the discharged fluid engages the impeller and causes the impeller and shaft to rotate. A pump is position adjacent to the turbine to receive the fluid being pumped to the process. The pump has an impeller mounted on a shaft and the shaft of the pump is operatively connected to the shaft of the turbine. Rotation of the turbine shaft causes the impeller and the shaft of the pump to rotate whereby the pump assists in supplying the fluid under pressure to the process and to recover energy from the high pressure fluid discharged from the process. Also disclosed is a method for recovering energy from an industrial process where a fluid is pumped at a high pressure into the process and at least a portion of the fluid is discharged from the process at a high pressure. The high pressure discharged fluid is directed into the inlet of a turbine. The inlet of the turbine is caused to rotate by the high pressure discharged fluid. The turbine impeller is mounted on a rotatable shaft. An impeller of a pump that is mounted on the shaft is caused to rotate by the rotation of the shaft that is caused by the rotation of the turbine impeller. The fluid that is to be pumped to the process is directed to the inlet of the pump. The rotating impeller of the pump raises the pressure of the fluid supplied under high pressure to the process and recovers energy from the high pressure fluid discharged from the process.

Abstract: In order to remove condensation from the enclosed volume of a double glazing panel an orifice is provided in one of the panes. When the moisture has been purged from the panel, a filter membrane, conveniently in the form of a patch, is attached to the pane to cover the orifice. The filter membrane is designed to allow the passage of air as the panel is heated, for example by sunlight, but inhibit the ingress of moisture as the panel cools again. The filter membrane may be a medial area of a unitary piece of mesh, the marginal portions of the mesh being attached to the pane. Alternatively, the patch may comprise a piece of material with a central hole and the filter membrane may overlie the hole. The marginal regions of the patch may have a film of adhesive for attaching the patch to the pane.

Abstract: ABSTRACT OF THE DISCLOSURE           A roll forming apparatus disclosed has a series of roll forming stations with a first group of stations having rollers that are adjustable to different width settings using the same rollers to form more than one width of ogee type gutter.  A cutter uses interchangeable cutting blades and die plates for shearing different gutter sizes to selected lengths. The cutter uses a rotary drive member to move the blade in a path having a relatively short stroke that performs a scissor-like cutting action to successively cut the walls of the formed gutters for each revolution of the rotary drive member.  A crank member for manually moving the cutter blade is collapsible and the crank handle is demountable for transport purposes.
