A liquid dispenser with a syringe reservoir including: (a.) a frame ( ) formed by upper bracket ( ) and lower bracket ( ); (b.) a body ( ) that is removable at the frame's upper bracket ( ) and provided at its upper end with a threaded part for installing an actuator ( ) and provided at its lower end with an insertion part for insertion into a syringe ( ) and an installation part for an attachment ( ), (c.) an actuator ( ) installed at the threaded part provided at the upper end of the aforesaid body ( ), (d.) a valve stem ( ) operated by the aforesaid actuator, and (e.) a valve seat member ( ) installed at the tip of syringe ( ) and formed to be removable at the aforesaid lower bracket ( ).

Liquid material dispensing apparatus

The present invention provides a hexahydropyridazine derivative of the formula (I): ##STR1## wherein R.sup.1 represents an alkynyloxy group, a cycloalkoxy group or an alkoxycarbonylalkylthio group, R.sup.2 represents an alkyl group, a phenyl group or a benzyl group, and X represents a halogen atom. This compound exhibits an excellent herbicidal effect on various weeds in treatment of field soil, foliage treatment and flooding treatment of paddy field, and has an excellent selectivity toward the weeds but not the crop.

Hexahydropyridazine derivative and herbicide containing the same as

An insecticidal, acaricidal or nematocidal composition which comprises an organophosphorus compound represented by formula (I): ##STR1## wherein R.sup.1, R.sup.2 and R.sup.3 each represents C.sub.1 to C.sub.4 alkyl; A represents H, C.sub.1 to C.sub.4 alkyl, C.sub.1 to C.sub.4 alkylthio or N(R.sup.4)R.sup.5 ; Z represents C(CN)R.sup.4 or N-R.sup.7 and an inert carrier show excellent effect for controlling harmful insects, mites and nematodes, do not give off a bad or irritating odor and exhibit very low toxicity to warm-blooded animals. R.sup.4, R.sup.5, R.sup.6, and R.sup.7 are defined in the specification.

Organophosphorus compounds and insecticides, acaricides and nematocides

A liquid cartridge storage case is used in connection with a plunger valve liquid dispenser to provide simplified and accurate control of liquid dispensing from a commercially available liquid cartridge, along with reduced downtime. The storage case includes a lower body section to which a commercially available liquid cartridge threadably mounts. Threading of the cartridge to the lower body section pierces a bottom membrane of the cartridge to allow liquid from the cartridge to flow into an internal passage in the lower body section. The internal passage communicates with a passageway of the dispenser through which liquid flow is controlled, via the plunger valve, for dispensing out of a nozzle at one end thereof. Pressurized air supplied from an external source to the inside of the case causes a cartridge wall opposite the pierced membrane to move toward the pierced membrane, thereby forcing liquid under pressure from the cartridge and into the dispenser. An additional liquid cartridge storage case may be connected to the liquid dispenser in parallel, thereby to allow dispensing from a liquid cartridge in one of the storage cases while the spent liquid cartridge of the other case is being replaced.

Liquid cartridge storage case for use with liquid dipenser

Insecticidal, acaricidal or nematocidal compositions which comprise a series of organophosphorus compounds represented by the following representative structural formulae: ##STR1## show excellent effect for controlling harmful insects, mites and nematodes, do not give off a bad or irritating smell and exhibit very low toxicity to warm-blooded animals.

Organophosphorus compounds, and insecticides, acaricides and nematocides

An adaptor for liquid dispensing of precisely controlled amounts through an outlet of a liquid filled syringe includes a valve shaft extended through an inlet of the syringe, along the syringe and seated against a valve seat assembly at the outlet of the syringe. The valve seat assembly and a cylindrical casing cooperatively mount the syringe to a housing assembly. A spring within the housing assembly biases the valve shaft to a normally closed position against the valve seat assembly. By pressurizing the liquid in the syringe, timer actuation of a solenoid within the housing assembly retracts the valve shaft away from the valve seat assembly to an open position to force the pressurized liquid through the outlet and out of the syringe.
