Title: Eye glass cleaning machine
Inventor: MAINES KENNETH E
IPC: B08B5/02
Filed: 1998-02-11
Abstract: Two similar representative versions of an eye glass cleaning machine constructed in accordance with the principles of the invention are seen. In each version an enclosure providing a base having a bowl forming an eye glass cavity supports a pair of eye glasses to be cleaned by means of adjustable clips. In the first version of the invention, a heated cleaning fluid and waste fluid tank and a rinse water tank are filled by a two-way drain valve. In the second version, a heated cleaning fluid tank, a rinse water tank and a waste tank are filled by a three-way drain valve. In both versions of the invention, an electronics card controls the operation of a pump, air pump and a solenoid valve, which determines from which tank (cleaning fluid or rinse water) the fluid supplied to spray nozzles will be taken. The electronics also controls heating elements in the cleaning fluid and rinse water tanks. The adjustable two-way or three-way drain valve allows the user to rotate a valve plate having a hole until it coincides with the appropriate fill port.

Title: Axle tilt control apparatus for industrial vehicles
Inventor: CHINO KENJI
IPC: B60G9/02
Filed: 1998-07-07
Abstract: An improved axle control apparatus for industrial vehicles.  A multi-movement hydraulic cylinder is provided at each end of a rear axle to couple the rear axle with a body frame.  Each cylinder has a pair of oil chambers, which are defined by a piston.  The oil chambers of the same cylinder are connected with each other by an oil line.  An electromagnetic valve is located in each oil line.  When the electromagnetic valves open the lines, oil flow between the chambers of the same cylinders is permitted.  This permits the pistons to move.  When the electromagnetic valve closes the lines, oil flow between the chambers of the same cylinders is prohibited.  This locks the pistons.  When the pistons in both cylinders are movable, the rear axle is permitted to tilt relative to the body frame.  The rear axle is locked by locking the piston of at least one of the cylinders.  Thus, if one of the cylinders is malfunctioning, the rear axle is locked by the other cylinder.  The reliability of the apparatus is improved accordingly.

Title: Composite film for controlling oxygen flux into thermal cells
Inventor: MCGUIRE KENNETH STEPHEN
IPC: B32B7/06
Filed: 1997-02-27
Abstract: A composite material for controlling oxygen flux into a thermal cell (10) comprises a bottom sheet (12) formed to have a pocket (14). The bottom sheet is impermeable to oxygen. A plurality of particles (20) is placed in the pocket. The plurality of particles reacts exothermally when exposed to oxygen.  A top sheet is sealed to the bottom sheet at a flange around the pocket to enclose the plurality of particles such that the particles cannot fall out of the pocket. The top sheet has a substrate (22) which is highly permeable to oxygen. The substrate is coated with an oxygen permeable silicone based elastomer (24) to a thickness which regulates an oxygen flux into the pocket when the top sheet is exposed to oxygen. The composite material further comprises an oxygen impermeable barrier film (28) bonded to the top sheet by pressure sensitive adhesive (27) for preventing exposure of the top sheet to oxygen until the body warmer is intended to be used. A method for making a top sheet material involves coating a silicone rubber layer onto a smooth surface, partially curing the silicone, pressing a porous substrate against the silicone rubber layer, and completely curing the silicone rubber such that it adheres to the substrate.

Title: Primer system for product distribution machines
Inventor: HUNDEBY DAVID ROBERT
IPC: A01C17/00
Filed: 1998-10-30
Abstract: A primer system for product distribution machines, such as an agricultural air seeder, a precision planter, a sprayer, or the like includes a tank or a bin for holding the product, a distribution system for conveying and distributing the product from the tank and a driving mechanism for driving the product from the tank into the distribution system at a certain rate. The driving mechanism can run automatically or it can be selectively operated, based on commands received from a controller. The controller may receive signals from a user interface and from sensing equipment, such as a ground speed detector, a pressure sensor, a flow meter etc. In a regular mode of operation, the controller runs the driving mechanism automatically at a rate calculated based on the signals received from the above mentioned systems. Most agricultural machines have the automated operation of the driving mechanism conditioned by the ground speed of the tractor being higher than a minimum speed. In a bypass mode of operation, the driving mechanism can be selectively operated by pressing a primer button on the user interface. The primer button triggers a bypass signal, instructing the controller to run the driving mechanism at a predetermined dispensing rate, regardless of other factors, such as the detected ground speed.
