The rib 84 tapers in the direction from a base 66 of the container towards an outlet 16, so that the fit between the rib 84 and a slot 24 in a guide 22 on the handset becomes progressively tighter as the container is inserted.

Abstract: An integral type processing unit has a photosensitive drum, a developing unit for forming a developer toner image on the photosensitive drum, and a cleaning unit for scraping off residual toners from the drum. The developing unit does not have sufficient internal volume for accumulating therein the developer toners whose amount meet with the service life of the other components. Therefore, toner containers are replaceably attached to the developing unit for supplementing the developer toners therein. In order to limit the replacement times of the toner containers, each of the toner containers are provided with a segment separable therefrom. Further, a receiving segment is provided at the developing unit engageable with the separable segment. The receiving segment has a predetermined number of receiving portions. If all receiving portions are filled with the separable segments, it becomes no longer possible to further replace the toner container with a new container.

Abstract: By employing two independent, separate and distinct flow paths which are controllably sequentially opened during use in a single actuation operation, an error-free, spill-free flame and explosion proof liquid delivery/filling system is achieved. In the preferred embodiment, both flow paths are normally maintained in a closed, sealed configuration, requiring an actuation force to controllably, sequentially open the flow paths. In addition, by providing a cooperating, mating liquid transfer assembly, the container on which the liquid delivery/filling system is mounted can be refilled with safety and ease, completely eliminating spillage of the liquid. In this way, a fully integrated, cooperating, liquid flow controlling system is realized.

Abstract: A dunnage bag valve and coupling arrangement comprises a valve stem having a spring loaded valve member which is movable to open a passage through the stem. A pair of circumferentially extending, diametrically opposed slots are formed on opposite sides of the stem. An axially extending opening is provided at one end of each slot for receiving a lug. A pair of lugs are formed on the inner cylindrical portion of a coupling so that the coupling can be pressed onto the stem and twisted, the lugs being introduced into the slot openings and then riding along the circumferential portions of the slots. An air hose is threaded to the coupling so that compressed air can be introduced through the valve stem into the dunnage bag. A fixed post inside the coupling opens the valve member when the coupling is engaged to the valve stem. To prevent rotation of the stem, teeth at the base of the stem engage teeth on the ring of a handle that is held while the coupling is pushed and twisted onto the valve stem.

Abstract: A standpipe to facilitate bleeding of air through the flexible filler spout of a waterbed mattress includes an elongated cylindrical tube adapted for a frictional slide fit within the spout end fitting so as to afford a substantially liquid tight seal between the tube and end fitting. A lip protrudes outwardly from the bottom of the tube to engage the underside of the spout and thereby resist removal of the standpipe from the spout. A collar at the top end of the standpipe seats upon the spout in the lowered position of the standpipe. A transverse closure plate closes and seals the top end of the standpipe, but air can escape through a sidewall opening adjacent to and below the closure plate. Just below the sidewall openings, a check valve is provided to allow the escape of air from the mattress, yet prevent air from being drawn into the mattress by suction. Pivotal handles on the threaded cap for the spout may be used to engage the standpipe for lifting it from the spout.
