Abstract: An on/off valve (O/OV) and directional valves (DV1, DV2) are packaged with a switching valve system (10) in a housing assembly (156, 157, 158, 160). The on/off valve (O/OV) is operated by a control handle (154) that is located at one end of the housing assembly (156, 157, 158, 160). The direction control valves (DV1, DV2) are operated by a handle (141) located at the opposite end of the housing assembly (156, 157, 158, 160). The control handles (154, 141) operate to position cams (152, 136, 138) which function to help position valve plugs. In a second embodiment, the handle (141) and cams (136, 138) for controlling the directional valves (DV1, DV2) are replaced by a solenoid valve system (SV2) . A second solenoid valve (SV1) is added to the control system for the off/on valve (O/OV). The solenoid valve (SV1, SV2) allow for a remote positioning of the controls for the off/on and directional valves (O/OV, DV1, DV2).

Abstract: A fluid valve assembly includes a housing, a valve, a rotatable driver received in the housing in operative communication with the valve, and an over-center linkage disposed between the driver and the housing. The housing includes an entrance to permit fluid flow into the housing and an exit to allow fluid flow out of the housing. The valve is disposed between the housing entrance and exit. The valve is configured in an open state to permit fluid flow through the housing and in a closed state to block fluid flow through the housing. Rotation of the driver from a first rotational position toward a second rotational position moves the valve from the closed to the open state, and rotation of the driver from the second rotational position to a third rotational position permits the valve to return to a closed state. The over-center linkage biases the driver to either the first or third rotational position.

Abstract: A hybrid fence system includes partial post and rail wrap components and a plurality of uprights, all formed of durable resilient plastic material. The wrap components partially cover existing wood rails and posts. The plastic uprights takes the place of conventional wood uprights, e.g., tongue and groove boards.

One face of the posts will remain exposed along a gap of the wrap component, thus allowing the rails to be secured directly to the wood post. The rail wraps are wrapped around the rails in a fashion similar to the post wraps, such that a gap is formed between free longitudinal edges of the wrap, leaving a corresponding area of exposed wood on each rail which allows for attachment of the uprights directly to the rails. The uprights have a generally tubular configuration including opposed longitudinal edges forming a tongue and a groove, respectively. The tongue includes a fastening tab.

Abstract: Method and apparatus generate a mixture of the vapor of an organic liquid such as tetraethylorthosilicate (TEOS) and an inert gas such as helium. The ratio of organic vapor to inert gas in the mixture is accurately and continuously controlled as required in semiconductor manufacturing. The apparatus encloses a bubbler chamber which is filled with an organic liquid (e.g., TEOS) to a set level that is automatically maintained. The liquid is also maintained at an exact temperature (e.g., 75° C.). Inert gas (e.g., helium) flows into the bubbler chamber at a controlled rate and continuously evaporates some of the liquid therein. The flow of liquid into the bubbler chamber is monitored by a liquid control circuit, and flow of gas is controlled by a gas control circuit. A feedback signal from the liquid control circuit to the gas control circuit incrementally adjusts gas flow into the bubbler chamber to keep the liquid therein at the set level.
