An apparatus for providing humidification in a breathing assistance system may include a first container at least partially defining a first volume for housing an absorbent material, a second container at least partially defining a second volume for holding a liquid, and one or more fluid passageways for communicating the liquid from the second volume to the absorbent material in the first volume.

Spill resistant humidifier for use in a breathing assistance system

The invention relates to a paint spray gun which comprises a gun base (2) and a material feed unit (5) interlinked via a threaded wedge connection Said threaded wedge connection comprises a threaded wedge element (14) arranged on the circumference of a substantially hollow-cylindrical connecting element (10) of the material feed unit (5) and a corresponding counter-element (15) on the gun base (2) The aim of the invention is to provide a connection for the material feed that can be produced at low cost and that is easy to handle For this purpose, the threaded wedge element (14) extends with a recess (19) across more than half of the circumference of the connecting element (10) and the counter-element (15) is arranged on a single-ended shoulder (16) above a receiving bore (4) of the gun case (2)

Paint spray gun

An apparatus for delivering a volatile material in a continuous manner is disclosed. The apparatus includes a delivery engine having a reservoir for containing a volatile material; a rupturable substrate secured to the reservoir; a rupture element positioned adjacent to the rupturable substrate; and a breathable membrane enclosing the reservoir, rupturable substrate and rupture element. In some embodiments, the apparatus includes a housing having a notch for compressing the rupture element and breaching the rupturable substrate as it is inserted into the housing.

Apparatus for delivering a volatile material

A device for controllably releasing a fluid into an ambient environment. According to a particular embodiment of the present invention, the device comprises a housing having a fluid compartment and an orifice compartment disposed adjacent thereto and in fluid communication therewith via an orifice. The fluid compartment contains the fluid for release to the ambient environment. The orifice compartment includes a fluid exit opening covered by a removable sealing element and contains an initial quantity of fluid when the device is in an inactivated state. A fluid restrictor is disposed adjacent the orifice to restrict fluid flow from the fluid compartment into the orifice compartment in the inactivated state. A gas-generating cell is in selective communication with the fluid compartment such that gas generated by the cell is directed into the fluid compartment when the device is in an activated state. A fluid membrane is disposed between the gas-generating cell and the fluid compartment that allows the gas generated by the cell to pass therethrough to the fluid compartment in the activated state while preventing fluid within the fluid container from passing therethrough to the cell in the inactivated state. The device is activated by removing the sealing element to allow the initial quantity of fluid to exit out of the orifice compartment via the fluid exit opening and activating the cell to generate gas and force fluid from the fluid compartment to the orifice compartment and out the fluid exit opening in a controlled manner.

Device employing gas generating cell for facilitating controlled release of fluid into ambient environment

The invention relates to a fluid reservoir for a paint spray gun, comprising a receptacle (1) and a lid that can be placed thereupon and is provided with a connecting element (3) in order to mount the fluid reservoir on the paint spray gun or an adapter. The receptacle (1) is provided with a ventilation hole (4) which can be sealed using a valve. In order to improve the tightness of the valve, said valve encompasses two valve seats for sealing the ventilation port (4), which are disposed one behind another in the direction of flow.

Fluid reservoir for a paint spray gun

An insect bait station (10) is disclosed. The insect bait station (10) includes: a reservoir (40) for holding a liquid bait (42), the reservoir (40) having a mouth and a closure for sealing the mouth such that the liquid bait is contained in the reservoir; a piercer (160) for opening the closure of the reservoir (40) such that a liquid wicking device positioned in the mouth of the reservoir may transport the liquid bait (42) from the reservoir (40) and through the mouth of the reservoir; and an activation member (80) for moving the piercer (160) into contact with the closure of the reservoir to open the closure, wherein the insect bait station also comprises an insecticide.

Insecticidal liquid bait station

A pressure sprayer (20) includes an accumulator vessel (142) adapted to hold a pressurized fluid therein and a container (68) that is configured to hold a chemical concentrate. A motor (156) in fluid communication with the accumulator vessel and the container (68) is adapted to be driven by the pressurized fluid and to pump the pressurized fluid and the chemical concentrate. A chamber (194) is adapted to receive the chemical concentrate and the pressurized fluid from the motor (156) to form a chemical solution. A nozzle is in fluid communication with the chamber (194).

Self-contained multi-sprayer

The present invention provides an animal test chamber that has one or more side walls, a ceiling, and a floor to define an internal space in which animals can be housed and exposed to a chemical agent, a door, a port for introducing animals, an exhaust port, and one or more of the following four features. The first feature is a projector for projecting an image onto the chamber floor to assist in the counting of the knocked-down animals. The second feature is the capability of automatically washing/cleaning the chamber after a test. The third feature is the capability of simulating real life insecticide application conditions. The fourth feature is the capability of automatically dispensing the contents of an aerosol can into the chamber.

Animal test chamber

Una estacion de cebo para insectos, que comprende: - un deposito (40) para contener un liquido (42), teniendo el deposito una boca (44) y un cierre (46) para sellar la boca (44) de manera que el liquido (42) este contenido en el deposito (40); habiendose situado un dispositivo (148) de extraccion de liquido por mecha en la boca (44) del deposito (40), para transportar el liquido (42) desde el deposito (40) y a traves de la boca (44) del deposito (40); y la estacion comprende, tambien, un cebo solido; - caracterizada porque como el liquido es un cebo liquido (42); - un perforador esta previsto para abrir el cierre (46) del deposito (40), de manera que dicho transporte de liquido pueda ocurrir; - un miembro de activacion (80) esta previsto para mover el perforador (160) a que contacte con el cierre (46) del deposito (40) para abrir el cierre (46); y - la estacion comprende, tambien, un insecticida.
