Abstract: A fluid container and dispenser including an elastomeric reservoir and a dispensing tube connected thereto and a valve to either allow or inhibit fluid flow into or out of the reservoir. One embodiment includes an elongate tube with a hole in one side and an elastomeric sleeve surrounding a portion of the tube. A sliding valve element is mounted in the tube to close the hole. The valve element is mounted on a second, smaller tube which slides within the first-mentioned tube. The sleeve is filled by sliding the valve element away from the hole and injecting fluid under pressure into the sleeve to expand it. The valve then is slid to its closed position. The combined first-mentioned and second tubes together form a straw to withdraw fluid from a secondary container into which fluid may be dispensed.

Abstract: A tapping lubricant dispenser apparatus is provided for use in numerically controlled automatic toolchanger machining systems to dispense tapping lubricant into a previously drilled hole before tapping. The tapping lubricant is usually a viscous tapping compound of the consistency of paste, grease or the like. The apparatus includes a toolholder of the type to fit into the machine spindle, a reservoir for a supply of lubricant--typically sufficient to run unattended for several complete cycles, e.g. at least one shift--and a reciprocating pump that dispenses the lubricant responsive to actuation by the numerical control system when the toolholder of this apparatus is fitted into the machine tool spindle.

The instrument may be used for writing or for dispensing the liquid.

Abstract: Liquid is transferred between a reservoir and a truck tank by means of a pump which pumps the liquid through a conduit leading to the tank and separably couples to the reservoir. An air opened, normally mechanically closed valve connecting the tank with the pump is operated when the pump is operated to permit flow between the tank and reservoir. The pump is operated by control mechanism that is operable to enable and disable its operation. It is connected to an energy source via a multiple position switching device which disables operation of the pump when the level of fluid in the tank reaches a predetermined height, and at the same time permits the safety valve to close. In another position of the switching means, the pump is rendered operable regardless of the fluid level in the tank and the valve will at that time also be open regardless of the fluid level in the tank.

Abstract: A vertical hollow tube closed at its top end has a first hole in its side wall adjacent its top end and is filled with gaseous deodorizer under pressure. A vertical hollow cylinder closed at its top end and open at its bottom end has a second hole in its side wall. The cylinder is vertically slidable up and down along the tube whereby the holes can be moved into and out of alignment. The deodorizer escapes from the tube to the outside through the holes when aligned and is otherwise confined within the tube. Spring means disposed within the cylinder between the top ends of cylinder and tube normally biases the cylinder in a position relative to the tube at which the second hole is out of alignment with and disposed above the first hole. When a shoe engages cylinder and tube with the cylinder disposed' inside the toe, the weight of the shoe overcomes the normal bias and the cylinder is moved downward until the second hole is out of alignment with and disposed below the first hole.
