Abstract: A fragrance dispensing machine for full service car wash installations administers a carefully controlled amount of fragrance concentrate to precisely scent customer vehicles. The machine is preferably mounted upon a wall adjacent the car wash lane for convenient access vehicles being washed. An associated hand-operated applicator gun interconnected with the machine administers a uniform dose of fragrance concentrate during each application, which is outputted as a fine mist. The machine cabinet provides storage space for bottles of fragrance concentrate. An external source of air pressure is applied to the cabinet for generating the mist. An elongated conduit interconnects the applicator gun and the machine and separate conductive tubes within the gun conduit individually transmit air and fragrance concentrates to an atomizer manifold disposed within the applicator gun. Mixing of air and fragrance concentrate is performed within the atomizer through vacuum venturi suction.

Abstract: A system for creating liquid gradients is disclosed, comprising at least two containers that can be manufactured separately, such as by molding plastic. Each container has an outlet near the bottom and an air vent near the top, and the outlets are connected via tubing to a receiving device in which the liquids are mixed. One container has a horizontal cross-section which decreases as a function of vertical position between the top and bottom of the container; the other container has a horizontal cross-section which increases vertically in a complementary manner. The containers preferably are held together by a rack or other means. As the liquids drain from both containers simultaneously, they remain in hydrostatic balance with each other.

Abstract: A battery-operated apparatus for dispensing comestibles has a housing to which a comestibles-receiving barrel is removably connected. A removable piston is nonrotatably slidable within the barrel and pushed through the barrel by a piston rod nonrotatably connected to the piston and slidably received within the housing. The piston rod has external screw threads over a substantial portion of its length which are engaged by internal threads of an encircling drive nut. A drive member rotatably mounted in the housing and having a through-bore for slidably receiving the piston rod is provided for rotating the drive nut. The piston rod and the drive nut constitute a reversible assembly so that, following use, the barrel and the piston may be removed from the housing for cleaning and the piston rod with the drive nut thereon may be removed from the housing, turned upside-down, and reinserted into the housing ready for another use.

Abstract: A user-controlled manually-actuatable pumpable dispenser for hydraulically-driven discharge of a stored fluid incorporates a flexible wall or web-like barrier capable of containing a highly volatile fluid while accomodating mechanical and hydraulic dispenser-actuating deformations for initiating or effecting a discharge of the stored fluid. The barrier is formed of a relatively thin wall of polytetrafluoroethylene (PTFE) material having a predetermined thickness selected so as to render the barrier sufficiently flexible for accomodating deformations in accordance with which a discharge of fluid from the dispenser is hydraulically effected.

Abstract: A hand-held, manually-actuated dispenser for selective discharge of a stored fluid includes a discharge outlet and a reciprocatable actuating member movable between a first position normally closing the outlet and a second position opening the outlet to enable a discharge of stored fluid. The actuating member carries an inadvertent-actuation locking element which is automatically engageable with an inwardly-displaceable portion of the dispenser housing. When an associated closure cap is seated about the discharge end of the dispenser during periods of nonuse of the device, the housing portion is inwardly-displaced by the cap into cooperative engagement with the locking element whereby movement of the actuating member out of its first, outlet-closing position and, accordingly, any release of stored fluid from within the dispenser interior are prevented.
