Abstract: A multi-function dispenser may be adjusted to obtain a spray or stream of the material dispensed, either as a long duration discharge of the material or as intermittent discharges corresponding to actuation of a trigger actuator, or as a continuous discharge during actuations of the trigger, depending upon functional design variables. Structure is provided for storing an accumulated amount of material upon repeated operations of the trigger, for subsequent prolonged discharge of the material, or the accumulating structure may be bypassed for intermittent discharges of the material as the trigger is operated, or the accumulating structure may function as a holding chamber whereby a continuous discharge of the material may be obtained while the trigger is being operated.

Abstract: A dispensing device for discharging material under pressure, includes at least one accumulating chamber for receiving and accumulating material to be dispensed and operable to discharge the material under pressure over a sustained period of time for use as desired, and at least one expansible chamber operable to incrementally move material from a container into the accumulating chamber for storage of the material under pressure, whereby a prolonged, pressurized discharge of the material can be obtained.

Abstract: A trigger operated dispenser includes a plurality of expansible chambers, with one of the chambers comprising a pumping chamber connected to be operated by the trigger, and another chamber connected to receive product from the pumping chamber and operative to expand and accumulate an amount of product for continuous discharge of the product through the nozzle, whereby continuous discharge of the product is obtained during both pressurization and intake modes of operation of the trigger operated pumping chamber.

Abstract: A non-propellant operated, duration spray dispenser includes structure for mechanically pressurizing the material to be dispensed by pumping it into an expansible bulb for storage under pressure for subsequent dispensing of the material, and a snap-acting positive shut off valve is provided to terminate discharge of the material when pressure falls below a predetermined minimum.

Abstract: A trigger operated dispenser includes a plurality of chambers with movable members therein, and operable to draw material from a container, pressurize it, accumulate a quantity of material under pressure, and discharge the material to a point of use. An adjustable member communicates with the chambers for selectively obtaining either continuous or intermittent discharge of the material.

Abstract: A mechanically operated mixing dispenser for mixing and discharging materials under pressure, includes a plurality of accumulating chambers for receiving and accumulating materials to be mixed and dispensed and operable to discharge the materials under pressure over a sustained period of time, and a plurality of expansible chambers connected with sources of the different materials and with the accumulating chambers for transferring the materials from their respective sources to a respective accumulating chamber for storage of the materials under pressure.

Abstract: An economical and easy to operate mechanically operated dispensing device has a rotatable actuator connected with at least one expansible chamber to effect operation of the expansible chamber to draw material to be dispensed from a container into the expansible chamber and to then pressurize the material. An expansible bulb is connected with the expansible chamber and with a dispensing nozzle, and has a volumetric capacity several times as great as the expansible chamber. Valves are associated with the bulb to control flow into and out of the bulb, whereby the rotatable actuator and expansible chamber are operative to repeatedly draw material from the container, pressurize it and transfer it under pressure into the bulb, the bulb expanding as material is added thereto, and the elasticity of the bulb being such as to exert a substantial pressure on the material in the bulb.

Abstract: A non-aerosol pressure dispenser includes a pressurization chamber having a piston reciprocable therein and a manual actuator extends from outside the chamber into operative association with the piston. The actuator is reciprocable in a first direction to move the piston to compress a spring engaged therewith and to draw material into the chamber. The spring urges the piston in a second direction to pressurize the material in the chamber and a discharge valve or nozzle is connected with the chamber to release the pressurized contents thereof over a desired prolonged period of time and at a sufficient pressure to obtain a fine mist of the material.

Abstract: A dispensing device for discharging material under pressure, includes at least one accumulating chamber for receiving and accumulating material to be dispensed and operable to discharge the material under pressure over a sustained period of time for use as desired, and at least one expansible chamber operable to incrementally move material from a container into the accumulating chamber for storage of the material under pressure, whereby a prolonged, pressurized discharge of the material can be obtained.

Abstract: A perimeter alarm apparatus includes a loop of wire to be placed around an area to be guarded and electrical circuitry connected with the loop for detecting the absence of a signal imposed on the loop. The signal imposed on the loop is produced by a sending unit worn by a child, for example, who is intended to remain within the area bounded by the loop. As long as the child is within the area, the sending unit will induce a signal on the loop, but when the child moves beyond the loop a predetermined distance, no signal is imposed on the loop, with the result that an alarm is sounded by the circuitry.

Abstract: A dispensing device includes a manually operable loading member carried by and accessible exteriorly of a container having a material to be dispensed, with the loading member connected through a gear arrangement with a material dispensing piston reciprocable in a dispensing chamber which is in communication with the interior of the container. Operation of the loading member in a first direction effects reciprocation of the piston in a first direction to draw material into the dispensing chamber, and a spring acts on the piston to move it in a second direction to dispense the material from the chamber through a nozzle for use as desired.

Abstract: An alarm apparatus which is activated upon immersion. The apparatus is adapted to be worn whenever the wearer is expected to be in the proximity of a body of open water and will sound an alarm should that wearer fall into the water. The apparatus is portable, self-contained and has a water activated release to automatically release the apparatus from the wearer upon immersion of the device. The alarm is mounted in a buoyant housing so that housing is self-righting to float to the surface of the water in an upright orientation so the alarm signal is emitted outwardly of the water when the housing reaches the surface. Various embodiments and actuating and release circuits are also disclosed.
