Abstract: A method for dispensing a protective fluid is set forth wherein a container is provided formed with a transparent storage portion threadedly receiving a cap thereto. The cap includes a lower end formed with a series of alignment bores for receiving tubular projections integrally formed coaxially upon an exterior surface of the portion of the cap to enable reciprocation of the upper portion relative to the lower portion. Positioning rods are positioned adjacent each of the bores to provide an abutment to enable effective alignment of the projections with the bores. The container is filled with a lemon juice concentrate, whereupon the container is prepared for transport by an individual. The upper portion of the cap may be rotated relative to the lower portion of the cap to permit reciprocation and projection of the lemon juice spray upon an attacker imposing oneself upon an individual.

Abstract: An aerosol spray dispenser of flowable pharmaceutical product is provided with a flotation stabilizing arrangement such that it will float in water in a stabilized erect position even when empty of product; a scale is associated with the dispenser so that the depth at which it floats can be read by comparing the position of the surface of the water in which it floats with graduations on the scale. The stabilizing action may be obtained by placing the dispenser in a floatable bottom-weighted vial, with the scale located in the exterior of the vial, and the combination of vial and dispenser then floated in water. In other embodiments the vial need not be used, in which case the dispenser itself may be bottom-weighted to assure its stabilized erect flotation and the scale placed on the exterior of the dispenser; or, a cap may be provided for the dispenser which is positioned on the dispenser while both are floated in the water, the cap being top-weighted so that the assembly floats stably upside-down.

Abstract: An automatic animal feeder has a motor driven auger for supplying milk powder from a storage hopper to a mixing vessel. The mixing vessel has outlets for the continuous supply of liquid feed mixture to animal feeding locations. An electrical pump supplies water from a storage tank in the feeder to the mixing vessel. The auger and the pump are connected to an electrical control unit for delivering powder and water to the mixing vesel simultaneously in batches, the batches being automatically timed to provide a required powder to liquid ratio according to the setting of concentration selector switches on the front panel of the feeder. The batches of powder and water are supplied to the mixing vessel together in pairs when the liquid feed mixture is below a level determined by a sensor in the mixing vesel. Calibration of the powder supply is carried out by weighing a sample batch dispensed during a fixed calibration period and setting the measured weight on a calibration dial on the front panel.

Abstract: A nozzle for applying an air-curable adhesive to sheets of paper normally is located in a storage position with the end of the nozzle inserted into a liquid in a sump. This prevents adhesive material in the end of the nozzle from drying out or caking and thereby clogging the end of the nozzle. When the nozzle is to be used for applying adhesive, the nozzle is lifted out of the sump, the sump is moved, and the nozzle is then moved into an operating position for applying the adhesive. Also disclosed is apparatus for automatically returning the nozzle to its storage position with the end of the nozzle in the sump at the end of a cycle of operation, or when normal operation stops because of a power failure, for example.

Abstract: A side unloading bin for storing and discharging free-flowing granular material, such as sugar, is supported on a floor capable of supporting the weight of the material in the bin and has side walls with a discharge opening near the bottom. A flexible, inflatable, generally cup-shaped, double-walled bag, having a slanted top supports the material on the floor, has its slanted top attached to the side walls, and is inflated to assist the discharge of the material through the discharge opening, particularly the material that will not discharge by gravity due to the angle of repose of the material. The discharge opening has a discharge gate and an openable hatch, to discharge to a conveyor. Controls operate from a material sensor near the discharge control and actuate inflation and deflation of the bag to ensure a continuous discharge of material.

A generator needle assembly is provided having a wire selected for insertion in the needle with critical push-fit clearance and a tapered ground pointed end having an acute included angle of less than 15 degrees. The plunger of the syringe is mechanically advanced while telescopically observing the droplet size. A pneumatic collet is used which air strips the droplet without turbulence to produce uniform sized single droplets without the inclusion of satellite droplets.

Abstract: A dispenser comprises a hollow body adapted to receive a container of product to be dispensed, a dispensing mechanism disposed below the hollow body and means within the body for puncturing a container of product inserted therein to permit discharge of product from the container into the lower portion of the body. The lower portion of the body defines a reservoir of smaller volume than that of the container whereby the product accumulated in the reservoir acts to seal the punctured container and control the discharge of product therefrom. The container and the body are of complementary shape so that the container may only be inserted into the body in one position.

Abstract: A liquid soap dispensing system includes a closed soap container having a manually actuated dispensing pump carried therebeneath, the container being separated by a partition into a lower soap reservoir and an upper refill compartment, the latter adapted to enclose therein a removable refill cartridge and having a downwardly extending refill will with a plurality of keys upstanding from the bottom thereof. The cartridge has an outlet neck, the outer bottom surface of which has a like plurality of slots. The neck is closed by a pierceable membrane recessed therein and adapted to be received into the well so that a cartridge opening member pierces the membrane to accommodate free flow of liquid soap from the cartridge to the reservoir. The cartridge is entirely closed to define the liquid level in the reservoir at the bottom of the neck, and a drain hole in the reservoir wall above the bottom of the neck but below the tops of the keys prevents bootleg cartridges from being used in the soap dispenser.
