Abstract: Liquid transfer apparatus transfers liquid between containers, and includes a liquid storage chamber having an inlet and an outlet; a pump chamber having an inlet and an outlet; a passage connecting the storage chamber outlet to the pump chamber inlet; a suction pump mechanism for sucking air from the storage chamber via the pump chamber inlet; and a valve for selectively opening and closing the inlet of the liquid storage chamber, allowing liquid to flow into the storage chamber by a pump and opening of the inlet. A carry case stores the liquid transfer apparatus and three different adaptors, which can be connected to an aperture of a container for use with a liquid transfer apparatus. One adaptor has a radially adjustable thread engaging components to enable the adaptor to be connected to different sized apertures.

Abstract: Liquid transfer apparatus (10) for transferring liquid from one container to another container including an elongate liquid storage chamber (12) having a liquid inlet (13), and a fluid outlet (16), a pump chamber (17) with a fluid inlet (18) and fluid outlet (19), a fluid flow passage connecting the fluid outlet of the storage chamber to the fluid inlet of the pump chamber, suction pump means (24) for sucking air from the storage chamber via the pump chamber fluid inlet, and valve means (26) for selectively opening and closing the liquid inlet (13) whereby liquid may, be allowed to flow into the storage chamber (12) upon suction being applied to the storage chamber (12) by the pump means (24) and opening of the liquid inlet (13). Also disclosed is a carry case for the liquid transfer apparatus and three different adaptors. Each adaptor can be connected to an aperture of a container for use with a liquid transfer apparatus.

Abstract: A hand held motor driven applicator (10) for applying liquids including weedicides selectively to undesired plants. The applicator includes a motor (12), and a rotor assembly (22) including a rotatable wick support (41) having one or more applicator wicks (45) attached thereto. The rotator assembly is supported for rotation, in use, about a vertical axis (43) by support structure (18). A drive assembly (23) is operatively connected to the motor and rotor assembly for transferring rotary drive from the motor to the rotor assembly. A storage assembly (26) is in liquid communication with the applicator wicks for storing a quantity of liquid for supplying the wicks with liquid while the rotor assembly is rotating. An elongate handle (15) is operatively connected to the support structure so that a user can maintain the rotor assembly proximal to the surface of the ground so that the applicator wicks may apply liquid to selective plants upon contact.

Abstract: The invention provides a rotary wick wiper apparatus (10) for plants, of the type wherein a rotor assembly (12) is operatively connected to a motor (15) whereby it may be rotated about an axis (13) disposed substantially vertically in use, the rotor assembly having a wick (17) beneath it for plant-wiping function and arranged to receive liquid from a reservoir (19) above the bottom of the rotor assembly (12) and movable with the rotor assembly; characterized in that the reservoir (19) has an air vent (28) on a portion thereof which is normally elevated and disposed inwardly relative to the rotor assembly axis of rotation, the air vent (28) being connected to one end of an air tube (29) of small diameter extending circuitously around the rotor assembly (12) and having its other end providing an air-intake opening (33) on a part of the rotor assembly disposed outwardly of the air vent (28) relative to the axis of rotation (13).

Abstract: Liquid handling apparatus includes a transfer vessel adapted to receive and retain a predetermined volume of liquid between an upper air-inlet and lower liquid inlet/outlet, the latter being an opening in the base connected to a liquid-flow delivery and suction pipe of desired length, the latter having an open terminal end downstream of a manually controllable on/off valve, the terminal end being adapted to be placed in liquid communication with a supply vessel or dispensing container.

Abstract: There is provided apparatus for use in applying a treating liquid chemical to surfaces at or adjacent a longitudinal channel and including a first chemical applicator assembly (11) and a second assembly (10) mounted on a frame (31) adapted to be connected to and extend from one side of a tractor (9) or other conveyance whereby the applicator assemblies (11, 10) may be drawn along said surfaces and raised or lowered in use, each applicator assembly having an applicator head (14, 13) for supplying said liquid chemical and being mounted on a support housing (17, 16) having wheel means (21) therebeneath, the support housing (16) of the second applicator assembly (11) being further from the tractor (9) than the other and the two being hingedly interconnected and tiltable relative to the frame (31) and to each other about parallel longitudinal axes for treating adjacent parallel surfaces which are not co-planar, each support housing (17, 16) being mounted on its said wheel means (21) in such manner that the latter
