Abstract: The present invention pertains to the construction of a manually operated trigger sprayer in which the sprayer housing has a reduced diameter dimension liquid discharge passage to increase the velocity of liquid flow through the liquid discharge passage, and in which the nozzle assembly has a novel configuration that securely attaches the nozzle assembly to the sprayer housing to prevent the increased velocity of liquid flow through the sprayer housing liquid discharge passage from dislodging the nozzle assembly from the sprayer housing. The novel construction of the sprayer housing and the nozzle assembly includes a resilient crossbar provided on the sprayer housing that crosses over the liquid discharge passage and a pair of resilient flanges on the nozzle assembly that engage over opposite sides of the sprayer assembly crossbar and securely attaching the nozzle assembly to the sprayer housing.

Abstract: A trigger sprayer has a venting apparatus with a unique construction that is formed by the combination of a sprayer housing of the trigger sprayer and a plug seal assembled to the sprayer housing. The plug seal includes a dip tube connector, a valve seat, an annular rim seal, and a portion of the air vent baffle apparatus that are combined as one integral piece.

Abstract: A manually operated trigger sprayer is constructed with a reduced number of parts and in a novel manner in which all of the component parts of the sprayer are constructed of a plastic material. The construction of the trigger sprayer replaces the conventional metal coil spring in the pump chamber with a pair of plastic bowed springs that are integral with the piston rod and are positioned outside the pump chamber. Constructing all of the sprayer parts of a plastic material enables a cost efficient recycling of the parts, which does not require disassembling the parts to remove a metal spring.

Abstract: A manually operated trigger sprayer is constructed with a reduced number of parts and in a novel manner in which all of the component parts of the sprayer are constructed of a plastic material. The construction of the trigger sprayer replaces the conventional metal coil spring in the pump chamber with a pair of plastic springs having inverted U-shaped configurations that are integral with the piston rod and are positioned outside the pump chamber. Constructing all of the sprayer parts of a plastic material enables a cost efficient recycling of the parts, which does not require disassembling the parts to remove a metal spring.

Abstract: A manually operated pump dispenser is attached to the top of a bottle of liquid and pumps and dispenses liquid from the bottle. The dispenser includes a pump housing containing a liquid pump chamber, and a pump plunger that is manually reciprocated in the pump chamber. A liquid piston is mounted on the pump plunger and is reciprocated in the pump chamber by the pump plunger. The liquid piston is mounted on the pump plunger for limited axial movement of the piston on the plunger. The movement of the piston on the plunger opens and closes a liquid flow path between the interior of the liquid pump chamber and a liquid discharge passage passing through the pump plunger.

Abstract: A closure is removably attachable to a container and comprises a dispensing orifice and a valve element that is biased closed over the orifice. By inverting the container so that a liquid contents of the container exerts pressure on the valve element, or by squeezing the container causing the liquid contents to exert pressure on the valve element, the valve element opens the dispensing orifice allowing the liquid contents to be dispensed from the container. On removing the pressure from the valve element, the valve element resiliently closes the dispensing orifice.

Abstract: One or more server-based constructs are projected into one or more corresponding desktop objects. Thereafter one or more events involving the desktop objects are processed according to behaviors defined during the projection using action handlers cached at a desktop client. The action handlers provide a mechanism for instituting the server-defined behaviors at the desktop, including the playing of locally cached web forms that provide a user with options for interacting with the desktop objects according to those behaviors. Any or all interactions with the desktop objects may be subsequently communicated to the server, which can accept or reject any changes and resynchronize an updated view of the object(s) to the desktop client.

Abstract: A manually operated vertically reciprocated pump dispenser has a simplified construction with two separate pumps that pump two separate liquids from a container and keep the two separate liquids separated from each other as they are pumped through the dispenser, mixing the liquids for the first time in a discharge passage of the dispenser just prior to the mixed liquids being discharged from the dispenser. The dispenser has a rotatable sleeve that covers the two pumps and is rotated to lock and unlock a dispenser head that operates the two pumps.

Abstract: This invention provides an apparatus and method for processing produce to reduce microorganisms thereon by treating the produce in a treatment chamber. The treatment chamber comprises a produce receiver disposed in the treatment chamber, a means for providing a gas stream comprising chlorine dioxide and a carrier gas into the treatment chamber, a chlorine dioxide sensor in communication with the treatment chamber, and a means for controlling the concentration of chlorine dioxide in the treatment chamber. The method comprises exposing the produce to an atmosphere comprising gaseous chlorine dioxide and a carrier gas in a treatment chamber and can comprise controlling the concentration of chlorine dioxide in the treatment chamber, moving the produce in the treatment chamber during exposure to the gaseous chlorine dioxide, spraying water to remove the gaseous chlorine dioxide, and purging the treatment chamber to remove any residual chlorine dioxide.

Abstract: A manually operated liquid foaming dispenser is attached to the top of a container of liquid and is manually reciprocated to dispense the liquid from the container as a foam. The dispenser includes a liquid pump chamber and an air pump chamber that respectively pump liquid and air under pressure to a discharge passage of the pump where the liquid and air are mixed, generating the foam dispensed from the dispenser. The air pump chamber has a tube valve controlling the discharge of air from the air pump to the discharge passage, and the air pump chamber is charged with air by opening the air pump chamber to the exterior environment of the dispenser.

Abstract: A nozzle assembly including a nozzle member, a cap member, a spinner and a foam tube. The cap member is rotationally mounted on the nozzle member and may be rotated from an “off-position” to a “foam-position” with continued rotation bringing the cap member to a “spray-position” and then to a second “foam-position” and then to the “off-position.” Rotation of the cap member drives foam tube from a retracted position to an extended position extending forward of the nozzle member when the cap member is in the “foam-position.” The spinner rotates to atomize liquid flowing through the assembly.

Abstract: A coaxial cable [10, 50] includes an inner conductor [11] that is separated from an outer conductor [13] by a layer of insulating material [12]. The outer conductor includes a thin sheet of metallic foil that envelops the insulating material and has a seam [14] that extends in the longitudinal direction of the cable. In a first embodiment, the insulated conductor is axially rotated (twisted) with respect to its own longitudinal axis. In a second embodiment, the outer conductor is wrapped around the layer of insulating material. In both embodiments, there is relative rotation between the insulated conductor and the outer conductor. This practice is referred to as relative insulated conductor rotation, and it significantly improves the structural return loss characteristics of a coaxial cable when the outer conductor includes an asymmetry, such as a seam, that extends in the longitudinal direction of the cable.

Abstract: A coaxial cable with standard coaxial structure of central conductor, foamed polyethylene dielectric, and outer conductor and having a jacket that provides sufficient flame resistance and smoke generation to allow the cable to be used in plenum spaces. The jacket includes a halogenated polymer with a heat of combustion less than 7000 BTU per pound and including a free-radical scavenger.
