Title: Ventilator for use in medical applications
Inventor: GRANT GRAHAM CAMERON
IPC: A61M16/00
Filed: 1979-08-17
Granted: 1983-03-03
Abstract: An electrically powered type ventilator for use in medical applications.The ventilator incorporates an expansible chamber (20), a gas inlet/delivery port (21) communicating with the chamber (20), an electric motor (35) coupled to a rotatable shaft (39) and a motion translating mechanism (40, 41, 42) which couples the shaft (39) to the chamber (20) to impart expansion and compression strokes to the chamber.In order to avoid problems which are associated with crank mechanisms which feature in prior art electrically powered ventilators, the motion translating mechanism (40, 41, 42) includes an element (42), preferably a positive drive link chain or belt, which is connected with the expansible chamber (20) and which is driven to move along a linear path during expansion and compression of the chamber.Expansion and compression strokes are imparted to the chamber (20) preferably by use of two motors (35 and 36) which have their rotors mounted to a common shaft (37), with the first motor (35) being arranged to drive the rotatable shaft (39) in a first direction whereby successive compression strokes are imparted to the chamber and the second motor (36) being arranged to drive the rotatable shaft (39) in a second direction whereby successive expansion strokes are imparted to the chamber.The extent of the expansion stroke is preferably determined by use of a timer device which operates to cause de-energisation of the second motor after elapsing of a predetermined interval of time.

Abstract: Magnetic tape is automatically wound on spools continuously transported on a conveyor system. The spools (3,3') are handled in pairs by a gripper unit mounted at the end of a linear actuator (5) and possessing a pair of spool guide elements (14). The guides are supported on a pivoted block rotatable through 180 deg. to collect a pair of spools from the feed conveyor. The block is then swung back through 180 deg. and the distance between the guides increases to locate them in the winding position to receive tape (4) from a supply reel (16). After filling, they are replaced on the conveyor.
