Abstract: A built-in tip having first and second tip members joined to a flexible packaging or bag and for dispensing product. The first and second tip members are capable of taking on generally conical shape that conforms with the conical shape of the bag. The bag having the built in tip is embodied with or without a non-invasive tear mechanism or non-invasive cuts for opening the bag. The non-invasive tear mechanism comprises a plurality of junctions formed in flexible packaging that that extend through the bag and partly into the first and second tip members.

Abstract: A support for stabilizing an elongated carriage-driving screw against whipping while permitting the carriage to pass the area at which the screw is supported including an elongated screw for driving a carriage, a base, spaced bearings selectively movable radially into engagement with opposite sides of the screw, and a moving linkage including a fluid piston and cylinder for selectively moving said bearings into and out of engagement with the screw, said bearings being either planar or concave, and in the latter instance, either fixedly or floatingly mounted.

Abstract: A device for clamping into engagement with the inside of a pipe comprising central shaft, rotatable actuator members axially spaced on the shaft and journalled thereon, piston and cylinder type of hydraulic motors coupled to the axially spaced actuators for rotating the actuators, spaced frames fixedly mounted on the shaft, plunger members mounted for radial sliding movement in the frames, and coplanar links connected between the plungers and the spaced actuators for moving said plungers radially toward and away from the inside of said pipe. In one embodiment the spaced actuators are rotated simultaneously in opposite directions because they are connected to opposite ends of the hydraulic motors. In another embodiment separate hydraulic motors rotate the actuators independently of each other.
