Patent number: 7987710Abstract: A pressure vessel 12 with a CO2 liquid level indicator 14, for use with a paintball marker 10, includes a magnetic float assembly 42 disposed within the pressure vessel 12 and adapted to float on liquid phase CO2 39 contained within the pressure vessel 12, in combination with a magnetically sensitive indicator 44 on an outer surface 40 of the pressure vessel 12 and which is adapted to detect and to display the location of the magnetic float assembly 42 within the pressure vessel 12. When connected to a conventional paintball marker 10, the pressure vessel 12 magnetically shows the indicated location of the magnetic float assembly 42, thereby showing the amount of liquid phase CO2 39 remaining within the pressure vessel 12. This remaining amount of liquid phase CO2 39 can be correlated to an approximate number of additional paintball rounds that can be shot before the CO2 is depleted.Type: GrantFiled: June 21, 2010Date of Patent: August 2, 2011Assignee: Gayston CorporationInventor: Mark W.

Patent number: 7950290Abstract: A method and apparatus for determining a mode of failure of a bond between an electrically conductive ball deposit and a substrate when breaking the ball deposit off of the substrate. The method and apparatus utilize tool force and displacement values to plot a force/displacement curve. The force/displacement curve is used to calculate the energy necessary to break the ball deposit off of the substrate. The energy value of a portion of a force/displacement curve is selected by reference to a peak force. In one preferred embodiment, this energy value is compared with a predetermined reference energy value to indicate a mode of failure. The peak force is preferably the maximum peak force, in the preferred embodiment, the method and apparatus distinguish between a ductile failure mode and a brittle failure mode.Type: GrantFiled: May 12, 2010Date of Patent: May 31, 2011Assignee: Nordson CorporationInventor: Robert John Sykes

Patent number: 7926617Abstract: A method and apparatus for changing engine motor oil more quickly and simply than previously existing methods. To change oil on a gasoline or diesel engine, the conventional oil filter is removed and an adapter is screwed in its place. An inlet oil port of the adapter connects with the oil filter inlet line and an outlet port of the adapter connects to the oil filter outlet line. The adapter top is sealed with a recessed O-ring extending around the periphery so that oil can be pumped through the adapter into and out of the engine without leaking. The adapter inlet and outlet ports are connected by hoses/tubes to an external container with its own internal piston. The engine is turned on to idle and the engine oil pump pumps used oil from the oil pan out through the adapter outlet port into the external container.Type: GrantFiled: May 15, 2009Date of Patent: April 19, 2011Assignee: Ashland Licensing and Intellectual Property LLCInventors: Frances E.
