Abstract: The bond strength between a pre-cured elastomeric member and a metal surface is increased by applying a phosphate coating to the metal surface. This is particularly suitable for use in formation of torsional vibration dampeners wherein an elastomeric member is compression fitted between an outer annular ring and a hub thereby decreasing slippage between the annular weigh and the hub.

Abstract: A torsional vibration damper mountable to a rotatable shaft. The torsional vibration damper is a composite structure including a body formed of a polymer, such as a glass-reinforced polyamide, that surrounds an insert formed of a structurally-rigid material, such as a metal. The insert includes one or more support flanges that extend radially outward into the polymer body. When the torsional vibration damper is removed from the rotatable shaft, axial forces applied to the damper are transferred by the support flanges to the insert such that the polymer body remains substantially stress-free. In addition to, or instead of, the support flanges, the insert may include torque-locking structure that locks the polymer annular body with the insert to prevent relative rotation therebetween.

Abstract: A dual gerotor pump is used for an automatic transmission. A dual gerotor pump which is driven by a central drive mechanism has a first chamber which continuously provides transmission fluid to the automatic transmission. The pump also has a second pumping chamber which selectively directs fluid to the automatic transmission when necessary. A valve mechanism is provided to divert fluid from the second pumping chamber back to the second pumping chamber so that it can recirculate thereby decreasing fluid pressure to the automatic transmission when it is not required.

Abstract: A backup power supply includes a housing with a central compartment holding an electrical generator preferably an alternator and a hydrocarbon powered motor. The housing further includes first and second side compartments. The first side compartment stores the electronic components of the generator. A top covers all three compartments and has two side overhangs and a forward overhang. The side overhangs provide air inlets to the two side compartments which in turn permit passage of air into the central compartment. The forward overhang includes an air outlet which allows air to be directed from the central compartment to outside the housing. The alternator itself includes a fan which pulls air from one side compartment into the central compartment. The motor has a second fan that pulls air into the central compartment from the second side compartment. Further the exhaust from the motor is encased in a shroud which leads directly to a passage through the top to the forward outside opening.

Abstract: A can washing apparatus includes a supply line or header connected to a plurality of risers. The risers are formed from a plastic material and are held to the frame of the can washing apparatus by an elongated metal support which is in turn welded to the frame of the can washing apparatus. The metal support absorbs the force of the spray thereby preventing the risers from moving and flexing during use.

Abstract: A nickel electrode prepared by depositing one of an oxide and hydroxide of a zinc-salt to an electrode substrate in a first step and, thereafter, depositing nickel-active material to the electrode substrate in a separate step.

Abstract: Isotopes of either germanium or silicon are separated by a chemical exchange reaction. Preferably the compound is a hydro halide or halide composition and the donor can be a wide variety of compounds such as a lower molecular weight alcohol.

Abstract: A combination forklift and truck secured together to allow the forklift to be transported from one site to another by the truck. The truck has a horizontal platform with a back end and has a mounting kit secured underneath the horizontal platform. The mounting kit comprises a mounting frame, a pair of sleeves and a pair of arms slidably received within the sleeves. The arms extend upwardly and outwardly from the back end of the horizontal platform of the truck and terminate in arm ends adapted to engage two hooks secured to the frame of the forklift. When the hooks of the forklift frame are engaged with the arm ends, the forklift is in a raised supported position above the ground.

Abstract: An earth mover includes a fixed scraper blade and a moveable floor section. The moveable floor section can be pulled rearwardly to provide an opening between the fixed scraper blade and the forward edge of the floor section. The floor section is mounted on tracks which run on the exterior of the sidewalls of the bowl. The forward portion of the tracks are angled upwardly which keeps the floor tight against the bottom of the bowl. When the floor is in the open position, it allows the floor to extend downwardly below the thick scraper blade. This allows the forward edge or blade of the floor section to act as a leveler as the dirt is being unloaded from the earth mover.

Abstract: A battery charger system for providing a temperature compensated charging output voltage to a battery. The battery charger system includes a voltage source and an output circuit coupled to the voltage source and the battery for supplying the charging output voltage to the battery. The output circuit includes a diode compensation network that is responsive to variations in temperature near the battery to vary the charging output voltage supplied to the battery. Methods for providing a temperature compensated charging output voltage to a battery are also disclosed.

Abstract: An earth mover scraper combination having chain driven elevator drive sprockets for each of two chains which are mounted on plates that include pins extending into the frame of the elevator support. Two jacks are likewise inserted into the frame of the elevator support and can be used to force the pins away from the frame support thereby forcing the sprocket away from the frame support and tensioning the chain. Preferably, the jack is a hydraulic jack that can be operated with a simple grease gun. Metal shims are then placed between the mounting bracket and the frame assembly to maintain the chain tension.

Abstract: A magnetic conveyor system for transporting ferro-magnetic cans through an immersion or electro-immersion coating bath includes a magnetic infeed conveyor for transporting the cans toward an inlet end of the coating bath, a magnetic coating conveyor for removing the cans from the infeed conveyor and transporting them through the coating bath, and a magnetic outfeed conveyor for removing the cans from the coating conveyor at an outlet end of the coating bath. The magnetic coating conveyor includes an endless conveyor belt which defines inclined inlet and outlet runs relative to a surface of the coating bath. The cans are transported on the conveyor belt with a closed bottom of each can magnetically held to the conveyor belt and an open top of each can facing outwardly from the belt. The cans are transported into the coating bath at the inlet run with the closed bottom of each can entering the bath before the open top.

Abstract: A multi-layer hydrocarbon vapor-impermeable tube is formed with a nylon outer layer and a vapor barrier inner layer such as ETFE, bonded together by two adhesive layers. The laminated tube is coextruded. The shear on the two adhesive layers are adjusted to bias the first adhesive layer towards the nylon outer layer and the second adhesive layer towards the ETFE barrier layer. This permits rapid coextrusion of the laminated tubing. Preferably, both adhesive layers are formed from a blend of nylon and ETFE. The ratio of nylon to ETFE can be adjusted so that the first adhesive layer is preferentially adherent to the nylon layer, and the second adhesive layer is preferentially adherent to the ETFE layer, and both adhesive layers are adherent to each other.
