Abstract: A rupturable closure for use with a flexible container that is especially suited for pouring viscous fluids such as motor oil. The closure is secured to the pouring spout or other dispensing opening of the container and retains the viscous fluid in the container as the container is brought into inverted position for pouring. Notwithstanding the ability of the closure to hold in the viscous fluid, the closure also allows the closure to breathe when the cap is removed so as to relieve small variations in pressure as the flexible container is first grasped for pouring and thereby prevent premature rupture of the closure before or as the container is inverted for pouring. Such a closure includes a membrane secured over the dispensing opening of the container. The membrane has a small primary vent orifice in the region over the dispensing opening that is sized to permit the membrane to breathe.

Abstract: An electric floor covering removal apparatus which is characterized typically by an electric motor fitted in a frame for driving a fan, a pair of hydrostatic pumps hydraulically connected to independent, hydraulically-operated wheel motors and a hydraulic gear pump for raising and lowering a landing gear with respect to the frame, deploying the floor covering engaging-implements of the apparatus and driving the apparatus to remove the floor covering. A pair of control arm levers are spring-loaded to neutral and serve to independently operate the hydrostatic pumps and the wheel motors in infinitely variable fashion, in both the forward and reverse directions. The driver's seat is mounted on an insulated cover or shroud that covers the electric motor, hydrostatic pumps and the hydraulic gear pump, as well as electrical gear and a hydraulic fluid reservoir located beneath these operating components.
