  • Publication number: 20060160684
    Abstract: There is provided a cart for transporting dies, molds, and similar objects. The cart includes a lift mechanism for raising and lowering a support surface to the height of the surface onto which or from which the die will be moved. The support surface includes a transfer mechanism for coupling to the die, either with an electromagnet or a suction device, to thereby slide the die as desired without damaging critical components on the exterior of the die. The cart also includes a motorized drive wheel assembly which provides a drive force in a forward or backward direction to assist the operator in moving a die that has been transferred onto the cart. The cart is powered by one or more rechargeable batteries. The cart enables a single operator to safely and conveniently remove, insert, and transport dies or other similar objects.

  • Patent number: 5341951
    Abstract: The present invention features a breather cap for use in venting an oil reservoir. The cap vents high-velocity air flowing out of the oil reservoir, entraining the droplets of oil that are suspended in the escaping air. The breather cap is designed to slow the speed of the escaping air. This slowing mechanism is usually a large-volume chamber that is typically placed within the bottom of the cap. The air is directed against a deflector plate or a deflecting surface on top of the chamber. This deflected air deposits the tiny droplets upon the deflection surface. The separated oil is caused to pool or accumulate and drip back into the bottom of the chamber and then into the oil reservoir. The purified, lighter air thus rises above the deflector and is then vented through exit holes located in the top or side of the cap.
