Abstract: A liquid waste collection chamber assembly adapted to be worn in the crotch region of a user includes a triangular collection chamber with a rigid inlet tube and a back flow valve. The inlet tube attaches to a condom catheter by way of a flexible tube. Liquid waste from the user flows into the collection chamber in response to gravitational force. The collection chamber is worn, attached and supported to the wearer in the crotch region by way of straps connected to a top portion of the collection chamber. The collection chamber also includes an outlet tube disposed above the inlet tube at a top portion of the collection chamber attached. The outlet valve is actuatable to open and allow expulsion of liquid waste from the collection chamber.

Abstract: A radiator and condenser bridge the front of an engine bay of an automotive vehicle. An electric motor powered ducted fan is disposed directly behind and in enclosing relation to the radiator and condenser to draw air through the radiator and condenser and convey the hot effluent to a location outside the engine bay. While the bay is intended to be ventilated by ram air, any hot spots that may occur in or adjacent the bay, due to an insufficiency or complete lack of ram air, may be ventilated by providing an ejector in association with the ducted fan system. Effluent from the ducted fan is conveyed through the ejector, which by means of venturi effect, creates a relatively low pressure zone. A relatively higher pressure zone at a hot spot is connected by means of a ventilating conduit to the relatively lower pressure zone of the ejector. A ventilating flow is induced through the ventilating conduit and entrained with the effluent for ensuing discharge to a location outside the bay.

Abstract: Ram air ventilation of the engine bay of an automotive vehicle is accomplished by providing ventilating openings in a transverse structural cross-member that bridges the front of the engine bay, and by collecting hot effluent from the radiator and condenser and directing same out of the engine bay.

Abstract: A phase adjustment mechanism for setting the phase of the engine camshaft relative to that of the crankshaft. The operative coupling of the crankshaft to the camshaft is via two sets of splines, one set having pitch different from that of the other set. A spline engagement ring contains a spline of one set on its O.D. and a spline of the other set on its I.D. The axial positioning of the ring controls the relative phasing and is accomplished by a screw and nut mechanism with the nut being operated by a worm drive that is under the control of the engine ECU.

Abstract: An axial flow ring fan has improved efficiency and reduced noise by making the leading edge of each blade a generally sinusoidal shape.

Abstract: A cooling system for a vehicle having an engine mounted transversely to the longitudinal axis of the vehicle, a transmission mounted substantially parallel to the engine, comprising a power takeoff coupled to the engine, and a first shaft adapted to be driven by the engine and a transmission shaft, a blower, mounted about the transmission shaft, a drive unit connected to and driven by the first shaft and drivingly connected to the blower for rotating same; a first heat exchanger; a first duct for communicating air generated by the blower to the first heat exchanger.

Abstract: A cooling system for a vehicle engine includes a shroud directing air flow to a heat exchanger or radiator in a direction horizontally transverse to the forward direction of movement for the vehicle. The shroud leads to an opening on a side portion of the vehicle body so that a top portion can extend from a leading edge to an operator compartment in a wedge shape manner to cover an engine compartment. The top portion is free of openings to permit uninterrupted air flow over the vehicle body.

Abstract: A cooling system for use with an engine and an associated engine driven flywheel. The system includes: centrifugal blower means fitted to and rotatable with the flywheel for developing a pressure differential thereacross; a housing enclosing said flywheel and said blower means for defining an air passage having a housing inlet for communicating air to said blower means and an output for permitting the discharge of air therethrough; air cooled heat exchange means connected to and positioned relative to the housing to permit air to flow therethrough by virtue of the operation of the blower means; damper means responsive to at least one engine operating parameter, for controlling the air flow through the heat exchange means; and compartment means for enclosing the blower means and housing and oriented to prohibit the entrance of ram air thereto and including inlet means for receiving non-ram air.

Abstract: A cross flow fan (10) imparts both radial and axial flow components to airflow passing through the fan, resulting in a conical exit airflow. The fan includes a hub (12) and circumferentially spaced, radially extending fan blades (14, 16, 18, 20, 22, and 24). Backing plate portion (34, 36, 38, 40, 42, and 44) is associated with each of the blades 14-24. The backing plate portions lie on a conical plane which rakes backwardly from the hub in a direction downstream from the fan. The fan blades are disposed in a plane oblique to their corresponding backing plate portions, so that they intersect the latter along a joining edge (50). Each of the fan blades includes portions having greater (56) and lesser (58) radii of curvature. The portions (58) of lesser radii of curvature cooperate with the corresponding backing plate portions (36) to provide a radial component to the flow through the fan whereas the leading edge portions (56) provide the axial flow component.

Abstract: A cooling fan for an automotive vehicle includes a spider having arms projecting from a hub. Rivets attach blades and reinforcing plates to each of the arms, and each of the rivets extends through the reinforcing plate, the blade, and the corresponding arm. Each blade has a depressed portion defining a rim circumscribing the depressed portion, and the corresponding plates have a depression defining a flange which is adapted to engage the rim when the blade is installed on its corresponding arm. The contour of the plate is different from the contour of the blade, but the rivet forces the plate to assume the contour of the blade when the plate and the blade are installed on the arm. Accordingly, the plate is preloaded to thereby transmit bending forces to the rim which would normally be taken by the portion of the blade adjacent the rivet.

Abstract: The combination with a flexible bladed fan of a vibration isolator coaxially attached to the fan. The isolator comprises a first rigid support attached to the fan, a second rigid support adapted for connection to the fan driver, and a resilient member intermediate and arranged to transmit torque between the first and second supports while dampening vibrations. The second support includes means for aligning the isolator coaxially with the fan and fan driver and the first and second supports are positioned coaxially with respect to each other.

Abstract: An automotive cooling fan having flexible, resilient blades which decamber with increasing rotational speed of the fan, the general curvature of the blades being formed by a multiplicity of spaced, generally radially extending bends in the blades; in preferred embodiments the blades have configuration resulting from said bends in which the general radius of blade curvature of the blades increases and the chord angle of the blades decreases from the blade roots to the blade tips.

Abstract: A flexible bladed automotive cooling fan comprising biasing members biasing both the upstream and downstream sides of th blades including a root portion of the upstream biasing member extending beyond the remainder of both biasing members, the blade thereby having a substantially increased natural frequency and a reduced amplitude of vibration at resonance as well as an improved airfoil configuration.

Abstract: A flexible bladed fan comprising blade assemblies having a reinforcing member contacting each blade along the leading portion thereof, the blade and reinforcing member spaced apart at a gap behind the leading portion and contacting again at a second position behind the gap, the reinforcing member biasing the blade in a downstream direction at the second position.
