Abstract: Electric multiple stage variable forced air induction systems are disclosed herein. A housing defines a conduit therethrough with an exit (output) opening and an entry (intake) opening. The exit opening is to couple to and provide airflow to an air intake opening of a combustion engine. The entry opening is to receive air for delivery through the conduit to the exit opening. A plurality of stages generate thrust to increase airflow through the conduit and to the air intake opening of the combustion engine. Each stage can comprise a turbine housing component, a turbine rotor to rotate about an axis and generate thrust on air as it passes through the conduit in a direction parallel to the axis, and a motor coupled to and configured to turn the turbine rotor. One or more processing devices receive inputs indicating engine parameters and control the motor of each stage.

Abstract: A system is disclosed for monitoring and controlling the air intake of combustion motor with a forced air turbine electronically coupled thereto for the purposes of controlling the same. A processor electrically linked to the forced air turbine electric motor controller and configured with defined parameters to correlate forced air turbine instructions with engine and intake air pressure conditions. The system includes sensors electrically coupled to the forced air turbine electric motor controller configured to send information from the air intake, forced air turbine, throttle position and other conditions of the engine coupled thereto. The forced air turbine electric motor controller is configured to control the air intake based upon the input received from the various sensors as compared to the data contained in the processor. The system provides turbine speed control to the mass of intake air.

Abstract: A cart is provided which may be manually pushed or pulled or towed behind a motorized vehicle. In a first embodiment of the cart, the cart has a three position pulling tongue. In a first position, the pulling tongue locks a rear set of wheels when the tongue is in an uppermost vertical position. When the tongue is lowered to a middle position, the cart can be pushed or pulled by hand. In a lowermost position, extending horizontally, the tongue can be connected to a motorized vehicle, such as a tow motor or tugger, or connected to the rear of another cart for multi-cart transporting. The tongue is made of polyurethane material for light weight and quiet operation. In case of wear, the tongue is easily replaced. In a second embodiment, a platform is raised above a base of the cart. The platform is pivotally mounted on the cart and secured in position by a locking pin. The axis of the tilt mechanism may extend parallel to or perpendicular to a longitudinal axis of the cart.

Abstract: In accordance with the invention, an intubation set is provided having an improved connector between the tube and a probe. In a preferred embodiment, the connector includes a deformable sleeve which at one end receives an end of the tube and at the other end is tapered to converge on the probe where it is permanently attached. The tube contains a solid insert which can be set in a compound such as silicone rubber and the sleeve is deformed radially inwardly to trap part of the tube containing the insert thereby locking the tube to the sleeve and hence to the probe. A method of making the intubation set is also provided. The invention also provides an improved intubation set for use in intubating the canaliculi without probing a healthy nasolacrimal duct.

Abstract: A sensor for use in machine wear debris monitoring transducers which detect metallic particles present in a flow of fluid, such as lubricating oil. The sensor comprises an inductive coil having a plurality of turns for surrounding a non-magnetic conduit. An electrically conducting screen is located between the coil and the flow of fluid, the coil being electrically insulated from the screen, so as to isolate capacitatively the contents of the conduit from the coil. The resonant frequency of a tank circuit incorporating the sensor is thus unaffected by changes in the dielectric properties of the contents of the conduit caused by air bubbles and/or water droplets in the flow of fluid. The screen may be a single turn of thin metal foil having a gap between adjacent ends, or a mesh, or a metallic coating sprayed onto the conduit.
