摘要:
The invention relates to portable liquid supply device, mainly for water from central and other sources or for suspensions, for example pharmaceutical products and nutrient liquids. The invention can be used in household, outdoors, in the garden plots, in health care institutions, for example, for patients with dysphagia, as the source of purified drinking water or nutrient liquids, which go to a patient easily. Liquid supply device, includes raw liquid vessel, pressure generating means, liquid treating unit, comprising a lid, liquid supply means, liquid treating element and raw liquid inlet element, characterized in that is configured to supply treated liquid in portions from 5 to 100 ml, with velocity 0.5 to 10 ml/sec.
摘要:
An apparatus and method for discharging liquids such as vapocoolants in stream or mist form includes the use of a filter to remove contaminants from the liquid prior to dispensing through the nozzle opening. A streamlined flow of liquid is delivered to the nozzle to prevent after spray and the filter spaced from the nozzle to inhibit pulsation of the dispensed liquid stream. The filter and nozzle are provided as an assembly mounted in a passageway in the container actuator.

An apparatus and method for discharging vapocoolants in stream or mist form includes the use of selected fluoroelastomers for valve parts to regulate discharge. The fluoroelastomers provide long-term stability to the vapocoolants to enable superior shelf life without minimal loss or contamination of the vapocoolant. In addition, a filter is provided to remove contaminants from vapocoolant prior to passage through the nozzle opening.

An aerosol dispenser having a transparent container for storing a propellant and a first compound under pressure. An actuator button normally closes a valve mounted on top of the container to control the dispensing of the materials from the container. An ampule containing a second material separate from the first material until the ampule is broken is positioned generally along the bottom of the container with a saddle shaped foot. A push rod extends from the valve and holds the foot in engagement with the ampule and breaks the ampule when the valve is first moved to its open position. The materials are mixed within the container and are dispensed through a filter mounted on a dip tube leading to the valve.

A retaining ring assembly. A retaining ring which is adapted to be positioned between a propellant cartridge of an aerosol dispenser, which cartridge has particles of propellant-adsorbent material therein, and a stem-obturating gasket of the dispenser has an annular cutting edge on the bottom thereof. The retaining ring is dipped in adhesive and pressed against a sheet of filter material so that the disc-shaped filter element thus cut out of the sheet is secured in the retaining ring. The retaining ring assembly is then assembled with the remainder of the dispenser.

A refrigeration system includes a water circulation system and a replaceable water filter. The refrigerator includes a sensor that determines if a water filter is present, and a user interface that prompts a user to purge a water filter upon installation of a new water filter in the refrigerator. The water filter may include a memory storage device that stores information concerning the allowable life of the water filter, the remaining life of the water filter, and other information. Information concerning the remaining life of the water filter and other information can be displayed or otherwise communicated to a user by the user interface.
摘要:
A metered dose valve for use in a pressurized metered dose dispenser for dispensing a metered dose of an aerosol formulation comprising particles of a medicament suspended in liquefied propellant, optionally in combination with one or more excipients, said valve comprising a metering chamber and at least one porous, fluid permeable, particulate semi-permeable body, said at least one porous body being positioned within a region of the interior conduit of the valve, for example within the metering chamber, or a pre-metering chamber and/or an internal channel upstream of the metering chamber.

摘要:
Fitted into the neck (14) of a container (16) is a securing part (12), in the central opening (20) of which there is located the mixer part (26) with mixing chambers (38, 40), covered over by a screen-like refining element (48). Arranged on the refining element (48) is a disk-like valve body (58), which interacts with a ring-like valve seat (60). For discharging foam, the actuating element (70) is pressed down, until the stop (78) bears against the counter-stop (78'). As a result, the valve body (58) reaches the open position, with simultaneous bending of the refining element (48), and air is forced through the air passages (32) and liquid is forced through the liquid passage (34) into the mixing chambers (38, 40) by virtue of the positive pressure in the container (16). The foam formed there is refined upon flowing through the refining element (48). On the way to the outlet (92), the defined passage (74), the fins (68, 102), the ribs (72'), the screen (86) as well as chicanes in the annular channel (96) ensure optimum foam formation and retarding of the foam, so that the positive pressure in the container (16) does not drop abruptly when the valve arrangement is opened.
