  • Publication number: 20050230434
    Abstract: A manifold includes a plurality of inlet passages provided in fluid communication between an inlet and an outlet passage. A housing retains a pressurized gas cartridge in sealed fluid communication with each of the inlet passages. A check valve is located in at least one of the inlet passages. The check valve is biased to a closed position that prevents gas from flowing through the check valve to the inlet of the inlet passage. Thus, gas cannot exit through the inlet when a pressurized gas cartridge is not sealed thereto. The housing retains a viscous product cartridge and forms a gas enclosure separated from a product enclosure by a movable wall. The gas from the pressurized gas cartridges passes into the gas enclosure and generates a force on the movable wall to dispense product from the product cartridge.

  • Patent number: 6261035
    Abstract: A chuck 40 includes a body 42 having a plurality of angularly spaced ribs 166, 168 and 170 formed in a forward cylindrical opening 48 thereof. A locking element 236 is movable within a passage 180 of the body 42, and is formed with a defined portion 242 which is extendable from the passage 180, through an inboard peak surface 172 of the rib 166 and into the opening 48. An actuator 44 is coupled to the locking element 236 and is biased by a spring 250 to urge normally the defined portion 242 of the locking element into the opening 48. A bit 62 is formed with a shank 96 with three grooves 100, 102 and 104 extending axially to a free end 112 thereof. A pocket 114 is formed in a base of each of the grooves 100, 102 and 104. The bit 62 can be manually inserted into the opening 48 of the chuck 40 such that the grooves 100, 102 and 104 are located drivingly over at least portions of the ribs 166, 168 and 170, respectively.
