A fill and relief valve arrangement for the introduction of fluid into and the selective venting of fluid from a fluid chamber includes a fill valve adjustably positioned within an open ended bore formed in a body with one end of the bore in communication with the fluid chamber. In one position of the fill valve, a flared end portion thereof is in sealing engagement with a valve seat formed at the one end of the bore for isolating the fluid chamber from a vent port open to the atmosphere with th...

A valve which is used to control the gravity-feed filling of containers by selectively permitting certain fluids to escape from the container while the container is being filled thereby controlling the amount of material which is admitted to the container.

An auto-fill flow valve for use in providing valving action in a conduit, the valve having a releasable locking mechanism which prevents the valving element from moving to seat against the valve seat until the locking mechanism is released. Also provided is a valve guide for receiving the releasable locking mechanism and holding it against the valving element.

Methods and structures are provided for filling cryogenic flasks such as those used in portable, liquid oxygen therapy systems. A circular baffle plate is disposed within the flask neck near the bottom thereof and is sized to allow a narrow annular opening between the baffle edge and the flask neck wall. The liquid fill line is extended downwardly through the baffle plate, so as to discharge liquid below the plate. The baffle plate functions to provide a gas-liquid separation zone within the fla...

A gas/liquid fill assembly for use in an evaporative cooling tower, chemical scrubbing apparatus or other device includes a plurality of facially-opposed corrugated sheets of material disposed in a substantially vertical, parallel relationship. The corrugations of each sheet are disposed at an angle to the horizontal with each of the corrugations extending continuously in substantially straight lines from one edge of the sheets to another edge. The corrugations in alternate sheets cross the corr...

The packing elements are made with flutes to reduce the amount of material and to provide for better heat transfer for expansion of the elements. The flutes are imparted during extrusion of the molten mass of thermoplastic material through a die opening by virtue of the opening having been formed with grooves.

A wet deck fill sheet is disclosed for use in making a wet deck fill for use in evaporative counterflow heat exchangers. One aspect of the sheet is that it includes transverse corrugations formed in at least one of the top and bottom edges of the sheet. Another aspect is the provision of a staggered array of substantially vertical spacers extending from one face of the sheet to space the sheet a predetermined distance from an adjacent sheet in the wet deck fill. The spacers are aligned to provid...

A toilet reservoir fill alarm including water level sensors which can be positioned in the water reservoir tank of a flush toilet to detect the presence or absence of water at a desired level. A switch responds to the water level sensors and produces a control signal during the absence of a desired level. The control signal operates a timing circuit in order to produce an output signal at the termination of a predetermined time interval. Responsive to the output signal is an alarm circuit. In th...

A splash bar fill assembly for a splash-type cooling tower includes a plurality of splash bars, each of which includes a one piece elongated member having a pair of upwardly converging leg members joined together to form an apex, and a vertical supporting rib member extending downwardly from the apex. The fill assembly also includes a wire mesh support system for the splash bars. The wire mesh supports the splash bars within the cooling tower in an arrangement of successive rows. Each row of the...

A composition is disclosed which is preferably produced by the beater saturation process in which water is removed from an aqueous furnish composition comprising asbestos fibers, an acrylic acid polymer and a synthetic rubber binder. The resulting composition can be formed into a fill for cooling towers which has improved capacity for a chlorinated rubber saturant.
