Abstract: The present invention relates generally to closures, and more particularly to an apparatus for sealing bags. In one embodiment, the invention includes an elongated sealing member and an elongated receiver portion to receive the sealing member. The receiver portion includes at least one engagement aperture to receive the sealing member and an opening extending along a length of the receiver portion. The opening further includes lugs that project generally outwardly from the receiver portion and proximate to the opening. In another embodiment, the invention includes a method for sealing a bag, including positioning a portion of a resealable bag proximate to the engagement aperture and positioning the sealing member proximate to the portion of the resealable bag and the engagement aperture. The sealing member is then pressed into the engagement aperture with the portion of the resealable bag interposed between the sealing member and the receiver portion.

Abstract: A cap for closing a threaded port in a vessel such as a pressure sprayer tank. A cup-shaped central portion of the cap faces into the vessel when the cap is installed onto the threaded port. The cup-shaped portion is provided with indicia indicative of volumes of material. In measuring use, the cap is inverted, allowing the cup-shaped portion be used as a measuring cup to which material may be added. When the desired amount has been added, the cap is re-inverted to dump the material into the vessel. Preferably, the cup-shaped portion has a skewed rim such that a portion of the rim forms a pouring lip. A pressure relief system permits relief of pressure when the vessel is opened at conclusion of use. Preferably, threads on the cap and the vessel are configured such that the cap seals against the vessel in one-quarter revolution of the cap.

Abstract: A sprayer has a spray shield and a spray shield retainer. The spray shield is removably attached to the spray shield retainer for efficient storage when not in use. The spray shield can be contoured to the body of the sprayer. The spray shield is configured for attachment to a spray wand proximate to a nozzle.

Abstract: A stackable pressure vessel has a substantially non-circular horizontal cross-section and is capable of containing fluids having at least 50, 250 or 1000 psi. The arrangement of various elements on the vessel serve to abate loading on the walls imposed by the pressurized fluid in the vessel. The vessel has creases therein in order to increase its strength. The vessel can also have arcuate recesses in its base. The vessel can also have a foldable pump handle. The handle is substantially flush with the vessel cap when in the storage position and the shaft of the handle is substantially axially aligned with a stem operably attached to a pump assembly when the pump handle is in the pump position.

Abstract: A pressure-limiting pump system for pressurizing a vessel, including a plunger terminating in a piston loose-fitting within a cylinder. The piston includes a flange forming the lip of an annular groove in the piston for supporting an O-ring seal. The groove is provided with a plurality of ports terminating in the piston within the cylinder. The O-ring is slidable on the piston groove surface. On the intake stroke, the O-ring moves to uncover the ports, and on the compression stroke, the O-ring moves to cover the ports to seal the compression chamber. When pressure exceeds a predetermined level, further compression causes air to bypass the O-ring and escape from the chamber, thereby limiting system pressure. The pump system may be mounted on-axis or off-axis in a tank sidearm. A handle is secured to the sprayer tank via shoulder inserts and is pivotable out of the way when filling the tank, yet can be locked in position as desired by a shift in pivot position.

Abstract: A swivel outlet assembly serving as a conduit for fluid flowing from a vessel to a hose has a swivel outlet top that is rotably attached to a swivel outlet base. A bore in the swivel top is in fluid communication at an acute angle with a channel of the swivel outlet base. The swivel outlet base is configured for attachment to a vessel and the swivel outlet top is configured for attachment to a hose. The outlet swivel top can have an integral hose connector. The swivel outlet assembly optimizes the operator's freedom of movement, thereby providing greater versatility, as well as minimizing stress on the hose and connector, therefore reducing the expense associated with maintenance and repair.

Abstract: The invention comprises, in one form thereof, a sprayer apparatus that includes a disengageable pressurized fluid source, a pressure chamber in fluid communication with the fluid source, a backflow valve, a sealed vessel, and a sprayer outlet. The backflow valve has two one-way valves separated by a weep mechanism and is positioned between the fluid source and the pressure chamber such that the two one-way valves allow fluid flow from the fluid source to the pressure chamber. The sealed vessel is in fluid communication with the pressure chamber. The sprayer outlet includes a shutoff valve in fluid communication with the pressure chamber. The shutoff valve normally prevents fluid flow from the pressure chamber to the sprayer outlet and is operable to allow fluid flow from the pressure tank to the sprayer outlet.

Abstract: In the scaled recovery system of the present invention, clients delay for an additional period of time prior to attempting to access a previously unavailable resource that has since become available, rather than accessing the shared resource at full speed once an initial back off interval is over. Through the continual increment and decrement of client back off intervals, the present invention provides dynamic tuning of overall system load in the case of overloaded shared resources.

Abstract: A combustor dome module includes a mixer tube having a hollow heat shield sealingly joined around the outlet end thereof. The modules may then be assembled in an array for defining the combustor dome, with each module being individually removable therefrom.

Abstract: A fastening system comprises a driving tool formed with a rectangular-shaped bit at its driving end, and a fastener such as a screw whose head is formed with a recess defining a central slot and four spaced undercuts each having parallel upper and lower walls and a side wall perpendicular thereto. The bit of the driving tool is inserted within the central slot of the recess and then rotated such that the side edges of the rectangular bit contact the side walls of two of the undercuts, and the top wall and bottom surface of the bit frictionally engages the upper and lower walls of such undercuts. Frictional engagement between the undercuts and the driving tool bit provides a positive, temporary interlock therebetween, and contact between the side edges of the driving tool and side walls of the undercuts permits the transfer of torque over a large surface to reduce wear.

Abstract: The invention comprises a syringe for extrusion of a semi-plastic mass, or a mass having a paste-like consistency. In a preferred embodiment, the syringe is so-designed to permit mixing of two components of a plasticizable mixture within the syringe barrel. The bore of the syringe barrel is flared to facilitate extrusion of the plastic mass therefrom. The parts of the syringe ready for use are packaged in a one-piece tray which serves not only for shipping and storing of the syringe, which may be preloaded with one of the components of the plasticizable mixture, together with the associated syringe parts, but which also serves, when opened for use, as a convenient tray for handling the syringe while mixing the two components of the plasticizable mixture prior to extrusion.
