Abstract: An die transfer and quick change system comprising at least four T-lift units installed in T-slots formed in the surface of the machine bolster. The T-lift units are installed in the bolsters so that there are at least two systems for positioning the die parallel to the machine or press and at least two systems for positioning the die perpendicular to the machine or press. A control mechanism is provided for selectively inflating and deflating the air bag in each of the T-lift units. The control mechanism provides for two separate T-lift systems which are inflated or deflated independently of each other. A pre-staging table is provided adjacent the machine or press bolster for pre-staging a plurality of dies thereon and for transporting selected dies to and from the machine.

Abstract: A fuel tank construction having a non-vented filler neck and cap, a shut-off valve sealed to the tank by a fluorocarbon bushing, resistant to both alcohol and sunlight, is positioned in the tank such that, upon bushing failure, no more than ten percent of a full fuel tank would leak therefrom, at least one protruberance having an air pocket formed therein and a vent system connected to the protruberance communicating between the air pocket and the atmosphere. The venting system consists of a long plastic tube attached to the vent and routed over the upper surface of the tank having the open end positioned such that any fuel which might discharge through the open end is directed away from the tank and any vehicle it might be attached to. Additionally, a low fuel sensor may also be incorporated and connected to the tank by a similar bushing as that used to connect the shut-off valve. The low fuel sensor utilizes a casing having pin holes surrounding a thermistor.
