Abstract: A medication dispenser has a medication container and a head removably coupled to the container to permit flow of medication from the container to the head and to permit recharging or replacement of the container or head. A medication passageway between the container and the head includes removable orifices for selectively regulating flow of medication from the container through the head. A plurality of teeth defining channels are provided on the head for the passage of medication from the head through the channels onto an animal. The head has a surface which is generally parallel to the surface of the animal, and the teeth extend from the head at an oblique angle to the surface.

Abstract: An apparatus for batch processing tennis balls for preserving their internal pressurization. The apparatus includes a high pressure reservoir and a lower pressure storage chamber integrally and unitarily housed within a single tank and separated by a bulkhead. An air compressor is connected to the high pressure reservoir and is controlled by a gauge apparatus to maintain a desired high pressure within the reservoir. The reservoir and storage chamber are connected together by a conduit which includes a low pressure regulator to maintain a desired pressure in the storage chamber. A passageway with an air-tight, removable lid provides access to the interior of the low pressure chamber for loading and unloading the tennis balls. The apparatus may also be used to repressurize tennis balls which have lost some of their inflation.
