Patent CA-2116553-C (CA)
Inventor: MIYAWAKI HIROSHI
IPC: G03B27/32
Filed: 1993-05-12
Granted: 1997-04-15
Abstract: A control strip holder having a light interrupting door opened and closed by the instruction of an external open-and-close instruction means is installed on the exposure table of an automatic printing and developing machine, which is provided with the open-and-close instruction means.  The control strip is automatically drawn out from the holder, held onto the exposure table by air-suction and transferred to the developing unit.  The control strip is drawn out by the holding force of the exposure table.  As a structure for concentrating the holding force on the driving of the control strip, a mask plate is provided on the control strip holder to cover almost all the holding zone of the exposure table. The leading end of the control strip remaining outside the control strip holder is held on the exposure table by a force which is stronger than that exerted on normal paper.  Thus, the control strip is transferred to the developing unit through the outlet by the paper conveying belt of the exposure table.

Title: Pressure switch
Inventor: ELLETT JAMES RICHARD
IPC: H01H35/38
Filed: 1994-08-02
Granted: 1998-06-16
Abstract: A pressure switch has a housing with an interior bore extending from one end to the other. A rod slidable within the bore and operated by external fluid pressure extends between a piston at one end of the housing and a mechanically operated electrical switch at the other end of the housing. A spring is disposed about the rod between a first stop on the rod and a second stop on the housing. The spring provides resistance against movement of the rod under external pressure. The resistance of the spring to movement is adjusted by a sleeve engaging the spring, with the sleeve threaded into the bore of the housing for movement longitudinally within the housing. The sleeve includes plural radially extending slots disposed around the sleeve. A port in the housing allows access to the sleeve and a cover is provided for the port. The cover includes a ring disposed around the housing and threaded onto the housing over the port. The electrical switch is mounted on a block that has a central hold down screw passing through the switch mounting block and threaded longitudinally into the housing. A pair of jacking screws flank the central screw, are threaded into the housing and are received by screw receiving counterbores in the switch mounting block. Each of the jacking screws supports the switch mounting block in fixed relationship to the housing, with each of the screws being accessible from the second end of the housing through the screw receiving bores.

Granted: 2004-04-13
Abstract: A heat recovery ventilator for use in ventilating a building, the ventilator having a single two-position damper operable such that in one damper position, heat is exchanged between a first flow of fresh air passing through the first path and a second flow of exhaust air passing through the second air path. When placed in the second damper position, fresh air is blocked from entering the ventilator and exhaust air is recirculated, passing through both air paths, and exiting through the fresh air outlet. In this mode of operation, exhaust air is inhibited from exiting through the exhaust outlet due to the relative pressures within the ventilator, thereby inhibiting the formation of a negative pressure within the building.
