Title: Clamping hacksaw blades
Inventor: BILNEY MICHAEL GRAHAM
IPC: B23D51/14
Filed: 1981-08-12
Abstract: This invention allows a fractured hacksaw blade to be re-used. A knurled and hardened steel roller 2 mounted on a pin between the flanges of a channel section 1, rotates eccentrically. A hole in the base of the channel provides replacement of the facility for re-fitting the blade within the saw frame. In operation, the fractured end of the blade attempts to withdraw from between the roller and the body of the attachment. This movement causes eccentric rotation of the roller to increase clamping action and allows the blade to be placed in tension. <IMAGE>

Title: Power plant and method for operating the same
Inventor: BRONICKI LUCIEN Y
IPC: F03G7/04
Filed: 1985-07-22
Abstract: A power plant includes an open cycle vapour heat engine e.g. a turbine (30) energized by a heated fluid such as geothermal steam which is condensed in a condenser (33) operating at a pressure greater than or equal to about atmospheric pressure and venting condensate e.g. to a rejection well via a pump 36. Uncondensed gases in the fluid are drawn off by a compressor e.g. for return to the well (35). The operation of the condenser (33) at a pressure greater to or equal to atmospheric pressure eliminates the need for a vacuum pump and thus increases the net useful work, produced by the plant. Associated with the open cycle engine (30) is a closed Rankine cycle organic fluid power plant (38) for producing power. The fluid may be other than geothermal steam. <IMAGE>
