摘要:
A self-contained, hand-held spray dispensing device includes an internal source of pressurized fluid that exerts a motive force on a pair of liquid ejecting elements to cause each to eject a liquid into a discharge line. The liquids remain separated until each exits its discharge port. A pressurized fluid is directed over the outlet ends of the discharge line beginning before a flow interrupter in the discharge line is opened to permit flow therethrough and ceasing after liquid flow is terminated. The pressurized fluid flow over the outlet of the discharge line aerosolizes liquids emanating from the outlet ends. The liquid ejecting element is connected to a force transmitting yoke. The yoke responds to pressurized fluid from the source to generate the motive force on the ejecting element.

The liquids remain separated until each exits its discharge port. A pressurized fluid is directed over the outlet ends of the discharge line beginning before a flow interrupter in the discharge line is opened to permit flow therethrough and ceasing after liquid flow is terminated. The pressurized fluid flow over the outlet of the discharge line aerosolizes liquids emanating from the outlet ends. Each liquid ejecting element takes the form of a piston disposed within a cylinder. The pistons responds to pressurized fluid imposed directly thereon from the source to generate the motive force on the ejecting element.

A gel cassette useful in electrophoretic separation of molecular fragments is disclosed, in which a gelatinous substrate is uniquely configured to concentrate similar separated fragments. Containment means is also disclosed which provides for the desired configuration of the substrate. The containment means further includes a cover design which locks into an open position to eliminate cross contamination. In addition, processes for the preparation of such cassettes and for use of the cassettes in separation and transfer apparatus are disclosed.

The present invention generally relates to both an apparatus, a test form and a method for evaluating sock-drop. More particularly, the present invention relates to an apparatus able to simulate particular forces exerted by human movements, a test form resembling a human leg as well as a method for testing sock-drop so that properties such as compression and comfort can be balanced.
摘要:
A bowed framed membrane is disclosed for use in automated direct blot electrophoresis and subsequent membrane process steps to develop a chemiluminescent image of the resultant blot of selected fragments and to detect that image. A frame made from a thin rigid plastic plate such as polyethylene is provided with a window. A membrane covers that window and is bonded on two opposing sides only while the frame is held in a bowed condition. The membrane is maintained under tension during processing by the bowing permitting processing at the elevated temperatures used in molecular biological procedures without loss of flatness. Processes for preparing such frames and various utilities are also disclosed.
