  • Patent number: 6212948
    Abstract: An apparatus and process for obtaining representative samples of fluids produced from one or more oil wells by means of a closed vessel chamber with lease water supply port connected to a lease water supply line, where a pressure sensor within such internal chamber is used together with a flowmeter and liquid-sensing probe or oil/water interface sensor employed in the fluid flow path lines to determine a rate of well production along with absolute or relative amounts of oil, water and gas contents.

  • Patent number: 5711330
    Abstract: An automated golf ball washer is provided with an integral agitation ball delivery means that is driven from the same power source that performs the golf ball cleaning function. The shaft that drives the washing mechanism has a cam thereon, that drives a reciprocating rod into the box holding the golf balls to be washed. The reciprocating action of the rod forces any balls jammed in the box to become dislodged, thereby encouraging a continuous feed of golf balls to the washing device.

  • Patent number: 5673812
    Abstract: An automatic golf ball dispenser wherein a hopper containing a large number of golf balls, which rest upon a rotary disc that is driven by a motor. To operate the dispenser, a customer deposits a form of currency into a control box, thereby actuating the rotary disc that will then dispense the desired number of golf balls to the customer. Controls contained within the control box govern various functions such as, how many balls are to be dispensed, ensuring that adequate safety features are in place, and checking that the dispenser is operating in a proper manner. The present invention also has an alternative wherein a signal is transmitted from the control box to a separate receiver indicating when the dispenser is in need of service.

  • Patent number: 4190978
    Abstract: A collapsible playhouse made from two halves of sheet material, such as corrugated cardboard, secured together. Material is applied at the edges to make them smooth and prevent cuts from being inflicted on the user. The applied material also strengthens the edge areas. It may be provided in the form of tape, or of tabs extended from the free edges to be folded back therefrom. The edges could be compressed to the normal sheet thickness by running the material through a roller press.
