Abstract: An improved system and method are provided for normally interconnecting a stationary flow line and a flexible flow line, and for automatically separating the flow lines in response to movement of the flexible flow line in excess of a preselected limit. A connection comprises a socket housing sealed to one flow line and a ball housing sealed to another flow line. The housings are separated automatically when a lateral force is transmitted through the flexible flow line to cause excess pivoting movement of one housing related to the other housing. The connection of the present invention is particularly useful for preventing rupture of a flow line during an intermittent pullaway of a portable vessel with respect to a stationary holding tank. In one embodiment, the connection includes at least three ball swivel surfaces for mating engagement with a socket swivel surface.
Abstract: A method of inhibiting the pitting corrosion rate of carbon steel in a cooling tower system comprising adding to a cooling tower water an effective amount of a corrosion inhibiting composition containing from about 1 to about 10 ppm of a water soluble molybdate, calculated as molybdate and from about 5 to about 25 ppm of a stabilized phosphate, calculated as phosphate, the corrosion inhibiting composition being substantially free of active zinc, and circulating the water in the system.
Abstract: An improved sulfider is provided for receiving high temperature catalysts from a hydrocarbon cracking operation and subjecting the catalyst to a sulfur-containing gas. The treating unit includes an outer metal housing and first refractory layer within the metal housing for minimizing heat loss from the treatment unit. A second refractory layer is provided within the first refractory layer and defines an interior chamber within the treatment unit, and a plurality of heating units are spaced circumferentially along the interface of the first and second refractory layers. The heating units substantially minimize the temperature differential across the second refractory layer and thereby minimize the heat loss from the high temperature catalyst within the chamber. The catalyst is continually passed into and out from the chamber, and the sulfur-containing gas is injected into a lower portion of the chamber to pass through the high temperature bed formed by the catalyst.
Abstract: A drinking vessel comprises a hollow cup having an upper rim defining a mouth opening. A lid removably mounted on the cup extends across the mouth opening to prevent spilling of liquid from the cup. The lid includes a base so mounted on the cup and having a flange extending inwardly from the cup's rim partly across the mouth opening and defining a port aligned with an inner part of the mouth opening. The lid further includes a valve element in register with the port, a seal on the valve element underlying the flange, and an actuator adjoining the valve element and disposed laterally outwardly thereof, such that when the actuator is depressed by downward force of the user's thumb, the valve element pivots downwardly, separating the seal from the flange. A spring normally biases the valve element upwardly with the seal against the flange.

Abstract: The present invention relates to a system of adjustable preformed ductwork for the conveyance of a fluid. The system uses a distribution box which includes an upper portion having a plurality of walls and a bottom plate. The distribution box may act either as a diffuser boot or as a splitter box. The distribution box is joined to interconnecting duct lines by adaptor conduits. The adaptor conduits are duct line which are adapted at one end for connection to an opening in a wall and are adapted at the other end for connection to adjoining duct line. A valve having a housing, a first cone and a second cone is also included in the system either in a duct line or in an adaptor conduit. The first and the second cone have matching apertures. The second cone is rotatable within the first cone such that the matching apertures may be selectively aligned or misaligned to adjust the flow of the fluid through the ductwork system.
Abstract: A process for preparing an alkoxylation catalyst in which a catalyst is formed by admixing an alkoxylated alcohol with a calcium or strontium containing compound which is dispersible in the alkoxylated alcohol, an inorganic acid and a titanium alkoxide, the pre-mix optionally being heated to a temperature and for a time sufficient to effect at least partial exchange reaction between the alkoxide groups of the titanium alkoxide and the hydroxyl groups of the alkoxylated alcohol, the pre-mix being used in an alkoxylation process to alkoxylate active hydrogen containing compounds such as alcohols.
Abstract: The present invention provides a flow-through instantaneous fluid heater system designed to satisfy the need for a heater not limited by being connected to a storage tank and which can be made using a plastic casing, incorporating cool-down when out of service and with features of venting and simplified flushing and draining. The system incorporates the use of one or more compartments, usually assembled in two compartment modules connected in series. Each compartment includes a casing having a hollow cylindrical interior region. An inlet aperture is located at one end of the casing and an outlet aperture is located at the other end of the casing. The lower end of each casing is closed by a removable base and the upper end of the casing is closed by a top plate and a heating element. The heating element is positioned axially in the interior region of the compartment. The heating element is activated by a control system which senses and compares temperatures of the water at the compartment outlets.
