Abstract: A post level having two spaced holders fixed to two plate-like body members with a notch between the holders. A floor member is integrally attached to the body members. Each holder provides a channel that receives the end of a level vial. One of the holders has a stop to engage an end of the vial. The other holder has a detent fixed thereto that urges and resiliently engages a second end of the vial to hold the vial in position in the holder.

Abstract: A rotatable rigid material valve operator is provided having a threaded shank threadedly engaged within a threaded blind bore formed in a valve member constructed of thermo plastic elastomer having an 80-90 "SHORE" scale durometer hardness and snugly slidingly disposed within a valve body bore against rotation relative thereto, the threaded shank being rotatable relative to the valve body against axial displacement relative thereto such that rotation of the threaded shank translates into axial shifting of the valve member within the valve body bore.

Abstract: A toothbrush holder for training the bristles of a toothbrush into a preferred shape utilizes a pair of opposed cam surfaces to urge a pair of rigid compression members against the sides of the mass of bristles along a line at a predetermined height on the bristles. The resultant bristle structure is maintained by repeated storage of the brush in the holder between use.

Abstract: Aquarium filtration apparatus having a generally trough-shaped filter housing, the rear wall having a bracket portion for hanging on an aquarium, an impeller assembly having a drive magnet being positioned within the bottom of the filter housing with a motor assembly coupled to the undersurface of the bottom with a power driven magnet on the motor assembly in spaced proximate relation to effect magnetic coupling with the magnet of the impeller assembly. An intake assembly is provided in fluid communication with the impeller assembly and with the aquarium water for drawing water from the aquarium into the filter housing. In a first embodiment, the intake assembly is an intake tube having a portion within the filter housing. In a second embodiment, the intake assembly includes a filter chamber within the filter housing in fluid communication with the impeller assembly with an intake tube coupled to the filter chamber for drawing water from the aquarium into the chamber.

Abstract: A dispenser for small animal food or the like, the dispenser including a base member having a planar surface and upwardly extending wall portion defining an elongate trough for tiltably receiving a plurality of unitary hopper members, each hopper member having a front wall, sidewalls, a back wall and a bottom with a pivot projection downwardly depending from the bottom, the pivot projection being generally coextensive or co-planar with the front wall. A depressor pedal member is generally co-planar with the bottom and is supported in generally parallel relation with the planar surface of the base with the hopper member supported within the trough. A cover is provided to completely enclose the plurality of hopper members, the cover having an aperture through which the depressor member extends, the cover aperture being in alignment with a hopper aperture formed in the front wall.
