Abstract: A container for metered dispensing of liquid. The container in an inverted orientation is connected at its withdrawal and venting aperture to an electromagnetically actuated metering valve, wherein the metering valve has a movable valve element. Within the inverted container there is a cup-shaped vessel having a tear-off cover which simultaneously forms the closure of the container and has its rim sealingly connected to the rim of the withdrawal and venting aperture.

Abstract: An adapter suitable for connecting a liquid measuring device to a variety of liquid containers of different size and shape without necessitating the use of different adapters. The adapter includes a sleeve portion which is fitted over the mouth and neck of the liquid container, there being affected a seal between the liquid container and the adapter. The opposite end of the adapter is attachable to the inlet of a liquid measuring device.

Abstract: An improved dosing valve for use in beverage dispensers, toilet tank additive dispensers, and the like which dispensers comprise substantially rigid reservoirs. The improved valve comprises an air-lock seal and another seal which may also be an air-lock seal. Dosing valves comprising such air-lock seals are particularly effective for obviating leakage of low viscosity, low surface tension, wetting type products such as toilet tank disinfectants comprising surfactant material. The seals are so disposed that the valve will dispense a metered dose of a liquid product from its associated reservoir each time a moveable component moves from an UP position to a DOWN position, and a dose-volume of air will be vented into the dispenser reservoir each time the moveable component is moved from its DOWN position to its UP position. The moveable member can be moved upwardly either mechanically, or by virtue of being buoyant, and it can be moved downwardly by gravity alone or by gravity supplemented by biasing means.

Abstract: Apparatus for batchwise feeding of powders or other particulate materials from a pressurized supply vessel with a sealable discharge orifice including a movable sealing-and-metering member and a seal against which it seals during periods of non-discharge.

Abstract: A metering valve, preferably electromagnetically actuatable, for the successive delivery of precisely measured volumes of fluid irrespective of inlet fluid pressure, including a valve core, slidably mounted in a cavity in the valve body, the top of the core closing a normally open fluid inlet when the core is moved to an uppermost position, and the bottom of the core closing a fluid discharge outlet when in its normal lowermost position, the volume of fluid discharged being the volumetric difference between the volume of the cavity and the volumetric displacement of the core.

Abstract: A liquid measuring device for use in dispensing a measured quantity of a liquid each time the pressure of liquid conveyed to such a device is reduced can be constructed utilizing associated inlet and outlet valves and an accumulator. The valves are constructed so that the inlet valve will be opened to the accumulator while the outlet valve is closed in response to an increase in the pressure of the liquid conveyed to the device. When the pressure of such supplied liquid is reduced as, for example, by the supply of liquid being cut off, the inlet valve is closed and the outlet valve is opened so as to discharge the liquid in the accumulator. Such devices are primarily intended for agricultural watering.

Abstract: A device for dispensing particulate or granulated material, comprises a container having sloped walls for retaining the material and feeding it to a plunger mechanism which can be actuated manually to discharge a portion of the material from the container. The plunger is disposed to move horizontally within an expandible sheath thereby permitting movement through the material.

Abstract: A hopper structure is disclosed for receiving sand from a main supply and selectively depositing the sand adjacent to one or more wheels of a motor vehicle. The sand deposition hopper is preferably arranged forward of the associated wheel and may be operated for traction sanding, braking sanding or the combination thereof.
