Abstract: Apparatus and methods relate to gas regulators for use with paintball guns. The gas regulator includes a poppet housing interchangeable by a user to modify output pressure of the gas regulator. The poppet housing includes markings visible externally on the gas regulator indicating to the user the output pressure provided. The gas regulator may further include a rotatable adapter for coupling with a paintball gun. A regulator piston that functions to control the output pressure based on the poppet housing selected acts in some embodiments on an internal balanced piston for selectively opening and closing flow through the gas regulator.

Abstract: Apparatus and methods relate to barrel arrangements for use with paintball guns. The barrel arrangement includes an insert that may be tubular and selectable by a user to have an inside bore diameter to provide desired fit with a paintball. An external barrel receives the insert and is attachable to a frame of the paintball gun. An externally mounted resilient band around an outside circumference of the external barrel facilitates centering and retention of the insert within the external barrel. Specifically, the external barrel includes a set of apertures through which extensions on an inside surface of the resilient band protrude into biasing contact with an outside surface of the insert.

Abstract: The present invention provides a more efficient firing system and bolt kit design for a paintball marker. In an embodiment of the invention, a firing mechanism comprises a bolt and a valve that are not mechanically joined together, so the valve opens and closes independently of the bolt's position. The valve opens away from a seat or seal in the same direction of travel as the paintball. The valve is part of the control system for the bolt such that the valve is acted upon to initiate the firing sequence.

Abstract: The present invention relates generally to a plasma source utilizing a macro-particle reduction coating and method of using a plasma source utilizing a macro-particle reduction for deposition of thin film coatings and modification of surfaces. More particularly, the present invention relates to a plasma source comprising one or more plasma-generating electrodes, wherein a macro-particle reduction coating is deposited on at least a portion of the plasma-generating surfaces of the one or more electrodes to shield the plasma-generating surfaces of the electrodes from erosion by the produced plasma and to resist the formation of particulate matter, thus enhancing the performance and extending the service life of the plasma source.

Abstract: The present invention provides a gas regulator with a diaphragm-type seal for a paintball marker or other type of gas-operated device. All regulator components are housed within a base to offer component longevity, easy adjustment of the regulated pressure, and simple maintenance. The diaphragm type seal acts as a sensing element where a seat rides on the interior surface of the diaphragm. Because the seat is positioned inside the diaphragm, a direct path is created to maintain constant pressure and increase accuracy from the seat to a pin valve.

Abstract: This invention relates to a construction equipment rental system for connecting construction equipment providers with construction equipment renters over a communication network. The construction equipment rental system comprises a server with an accessible memory having records of a plurality of items of construction equipment offered for rent by the providers, a record of at least one provider, and records of a plurality of renters thereon. The system further comprises a booking engine component configured to receive user-inputted data from a renter, access the records in memory, deliver an editable compact booking form for the required item to the renter, monitor the input of data into the compact booking form, and, in response to the input of data by the construction equipment renter, expand one or more of the collapsed sections for receipt of further user-inputted data. In this way, less data in a more compact, manageable user interface may be provided.
