Abstract: A stepper motor proportionally controlled bellows valve system comprising: a valve manifold; one or more stepper motors; and one or more bellows valves. The one or more bellows valves may comprise a bellows, a sealing washer, and a profile washer. The sealing washer is configured to removeably engage with a vacuum orifice rim. The profile washers are configured to stick into the valve orifice, such that the profile washer defines a flow through the valve.

Abstract: A foam dispensing article is provided which includes a reservoir for receiving a liquid product and an operating unit for dispensing foam as an air-liquid mixture. The unit includes an air pump, a liquid pump concentrically surrounded at least partially by the air pump, an operating component positioned above the pumps containing a foam forming screen device, and a spring system. The spring system functions to return pistons of the air and liquid pumps to an unactivated position and includes an inner spring positioned internally concentric to the air piston. The improvement of the present invention is characterized in the spring device having a return force greater than 4 lbs. (17.8 N). In one embodiment, the spring device includes both an outer spring conically tapered and surrounding an inner spring. The outer spring provides the required force in excess of 4 lbs. (17.8N). Less liquid drip and piston stickage is achieved with the improvement to the spring system.

Abstract: The present invention relates to methods and compositions useful for treating and preventing conditions in which inhibition of nitric oxide synthetase is beneficial. These conditions include stroke, schizophrenia, anxiety, and pain.

Abstract: Amidine derivative compounds of formula I as defined in the Specification having nitric oxide synthetase inhibitory activity as well as processes for the preparation of and compositions containing said compounds are described.

Abstract: A multi-cavity dispensing container is provided for the co-extrusion of at least two flowable materials. The container includes a refill cartridge and a reusable base. The cartridge contains a pair of separate parallel cylinders within which are carried the flowable materials. At a lower end of each cylinder is a piston head. The lower surface of the piston head is configured as a hollow recess. The reusable base is formed with a pair of separate parallel piston support posts. These posts are characterized by a central hub surrounded with at least two outwardly projecting arms. Tops of the posts can readily engage within the recesses of the piston heads. Consequently the refill cartridge and reusable base can be readily engaged and disengaged from one another.

Abstract: A dispensing package is provided with a container and a cap. The cap includes a mechanism to fittingly engage across an open end of the container, a top portion defined by a deck, a skirt wall surrounding the deck, at least one dispensing orifice formed in the deck, a locking aperture with a wide and a narrow area preferably in a T-shape, a lid hingedly attached to the deck, a flexible post projecting downwardly from the lid, and a release mechanism along the skirt. The flexible post has an enlarged section at an end thereof which can lockingly engage underneath landings that define wide and narrow areas of the locking aperture. A flexible area along the skirt can be pushed inward against the enlarged section of the post to dislodge same from underneath the landings thereby opening the lid.
