Abstract: The invention is a device which works similar to a ‘liquor dispenser’. To use the invention the original cap on the beverage carton must be screwed off. The invention screws onto a screw top beverage carton (usually milk/cream carton also referred to as a Gable Top Carton usually made of a cardboard type material). It has a straight pour spout which always keep the spout in pouring position and two chambers. These chambers contain steel balls that function according to angle and pressure when the invention is secured onto the beverage carton threaded neck and is raised to pour liquid into a cup. The steel ball in the main chamber acts as a stopper. This occurs when a specified amount of liquid has rushed through the two side hollow windows of the chamber and out of the spout. When the ball rolls to the top wall of the main chamber it blocks excessive liquid from exiting the spout thus creating a measured serving.

Abstract: A method of assembly of a fluid dispenser of an apparatus for an automated biological reaction system is provided. In the processing of a biological reaction system, there is a need for consistently placing an amount of fluid on a slide. In order to accomplish this, several methods are used including a consistency pulse and a volume adjust means. Moreover, in order to reliably operate an automated biological reaction system, the dispenser must be reliable, easy to assemble and accurate. Among other things, in order to accomplish this, the dispense chamber is substantially in line with the reservoir chamber, the reservoir chamber piston is removed, and the flow of fluid through the dispenser is simplified. Further, in order to operate the automated biological reaction system more reliably, the system is designed in modular pieces with higher functions performed by a host device and the execution of the staining operations performed by remote devices.

Abstract: A method for installing plumbing fixtures in a multi-story building having a waste stack includes a stop valve between the waste output of each fixture and the waste stack, the valve allowing the waste water to flow from the fixture toward the waste stack, but preventing flow from the waste stack back into the plumbing fixture.

Within the body there is suspended a stop ball having a diameter larger than that of the ball seat in the upper outlet. When water attempts to back up from the waste stack in the direction of the stop valve, the ball is forced against the upper seat and blocks the water flow.

Abstract: A fluid flow control valve within a pop-up sprinkler arrests fluid flow through a riser of the pop-up sprinkler under abnormal flow conditions, such as when the riser is broken or a sprinkler head is removed from the riser. The riser, which is movable relative to a housing of the pop-up sprinkler, is attached to a sprinkler head which distributes water to the surrounding area. A valve seat device is disposed within the riser. A stopper is positioned within a valve passageway defined by the valve seat device. The stopper selectively engages the valve seat to inhibit water flow through the riser under abnormal flow conditions. A biasing device prevents the stopper from engaging with the valve seat under normal flow conditions.

Abstract: The present invention is a valve that shuts off only upon excess flow of liquid. A ball is seated within a ball holder. The ball holder has a circumferential side wall. An inlet orifice and one or more circumferential apertures are defined in the circumferential side wall. An outlet orifice is defined in a surface disposed above the ball holder. The ball holder may be disposed within a main body which directs all material flowing in the valve to enter the ball holder. Excess flow of liquid effects a shut-off position of the valve when the excess flow of liquid encounters resistance caused by the circumferential apertures. The resistance causes the liquid to flow through the inlet orifice at a flow high enough to push the ball upwards to a height at which the flow of liquid through the circumferential apertures carries the ball further upward to effectively seal the outlet aperture, at which point the sealed position is maintained by hydrostatic pressure.
