Abstract: A system and method are provided for selectively dosing and dispensing a predetermined liquid material in and from a pre-dispensing measuring sight glass container vessel, wherein a housing is disposed to receive a pressurized fluid stream, to provide an intermediate measurement and storage vessel for the liquid material and to provide a selectively operable valve assembly that is disposed in a flow path defined in the housing. The housing includes an inlet, an outlet, and an intermediate portion extending therebetween, which is formed with an admission port for admitting the predetermined liquid material. The valve assembly is disposed between the housing's inlet and outlet, and may be selectively operated to fill the sight glass container from the source container; or, to dispense the liquid material from the sight glass container; or, to clean the sight glass container; or, to just provide a flow of the pressurized fluid without any liquid material.

Abstract: An improved pressurizable container and closure. Some embodiments provide an improved sealing arrangement for a pressurized container and closure. Other embodiments provide an improved closure is easier to grasp and/or manipulate. Some embodiments are directed towards a venting assembly for a pressurizable container.

Abstract: A dispenser for mixing and dispensing a liquid chemical concentrate from a container with a dilutent. The dispenser includes a rotatable and slideable eductor assembly. Both a high and low flow rate can be obtained with simultaneous adjustment of concentration of the chemical concentrate. The dispenser has a high degree of accuracy of the amount of dilution of the chemical concentrate as well as positive positioning of the high and low flow rate. The dispenser also provides for proper selection of concentrate during operation and has a lock-in feature during operation.

Abstract: A dispenser for mixing and dispensing a liquid chemical concentrate from a container with a dilutent. The dispenser includes a two piece slideable eductor assembly, one of which is also rotatable. Both a high and low flow rate can be obtained with simultaneous adjustment of concentration of the chemical concentrate. The dispenser has a high degree of accuracy of the amount of dilution of the chemical concentrate as well as positive positioning of the high and low flow rate. The dispenser also provides for proper selection of concentrate during operation and has a lock-in feature during operation.

Abstract: The arched multi-segmented ramp assembly of the present invention has the advantageous qualities of being portable, lightweight, easily deployable and storable. Identical step links have keystone-shaped sides that abut adjacent members and are joined one to the other by knuckle-like hinges, both of which structural features impart to the unrolled assembly a gently arcuate contour, thereby enhancing the ramp's strength to weight characteristics compared to ramps of the prior art. The hinge connections further permit the ramp to be rolled up for easy transport and storage. Because of its modular design, the arched ramp may be assembled using varying numbers of component step-links, thus providing a user with the flexibility to form a ramp assembly with lengths suitable for different particular applications.

Abstract: An enclosure illumination system (10) is provided. The enclosure illumination system (10) is mounted on an enclosure (12). The enclosure illumination system (10) includes a solar battery (16), a light element (14), and a motion sensor (18). When external light impinges upon solar battery (16), light (14) is prevented from actuating. When solar battery (16) is not exposed to external light, for example, at nighttime, light (14) may be actuated by signals transmitted by sensor (18).

Abstract: A method for simultaneously processing a plural number of samples, each held in its own container and including a fluid containing particulate matter. Each of the containers with its respective sample therein is closed by a respective cover assembly comprising a pump, a filter interposed between the container and the pump, and an agitator projecting into its respective sample. Each container is engaged by a separate container receiver, each pump is engaged by a separate pump receiver, and the container receivers are moved relative to the pump receivers simultaneously to mix the samples. Thereafter all of the pump receivers are moved relative to the container receivers to operate all of the pumps simultaneously to move the fluid of each sample through its respective filter.

Abstract: An apparatus for simultaneously processing a plural number of samples, each of the samples including a fluid containing particulate matter. The apparatus is useful in cytology to collect a uniform monolayer of cells from a biological fluid. Each of a plural number of processing assemblies (corresponding to the plural number of samples) comprises a container, an agitator rotatable relative to the container for contacting and dispersing particulate matter in the fluid, a filter assembly including a filter for collecting particulate matter, and a pump for moving the fluid through the filter. Each container is supported on a separate container receiver, and each pump is engaged by a separate pump engagement. A rotary driver effects relative rotation of the agitators and their respective containers simultaneously to mix the samples in the containers.

Abstract: There is disclosed a sprayer apparatus for selectively spraying or dispensing multiple fluid components. The apparatus comprises a housing having a first inlet and an first outlet, the first housing inlet being adapted for attachment to a garden hose, the first housing outlet being in fluid communication with the first housing inlet; and an insert member having a first inlet for receiving fluid and a first outlet for dispensing fluid therefrom, the first insert inlet being in fluid communication with the first insert outlet through a passage defined by the insert member, the insert member being mateable with the housing so that the first housing outlet mates with the first insert inlet so that a fluid can flow from the first housing inlet to the first insert outlet. A method of spraying a fluid is also disclosed.
