Abstract: An inflatable test plug for insertion into a two way clean out during hydrostatic testing of a building's interior sewer pipes. The test plug includes a hollow cylindrical body portion having a closed top, and a closed bottom portion. The test plug is adapted to receive and hold air under pressure during an inflation phase and to release the air under pressure during a deflation phase. The cylindrical body portion and the closed bottom portion of the test plug body are adapted to expand during inflation. The closed bottom portion is adapted to expand prior to the cylindrical body portion during the inflation phase, and adapted to deflate prior to the cylindrical body portion during the deflation phase. The closed bottom portion has opposing locking indentations in its outer surface adapted to receive opposing inwardly extending projections located in the mid-portion of the two way clean out.

Abstract: A fishing device that can act in one mode as either a diver or side diver, and in a second mode as a side sub-surface planer. The device includes a top plate, a curved bottom plate joined at their leading and trailing edges. Side plates are attached to the right and left sides of the top and bottom plates to thereby form a watertight compartment. A keel member is mounted on the curved bottom plate in a manner adapted to allow the keel member to be adjusted and held at any position between substantial abutment with the bottom edge of the right side plate and substantial abutment with the bottom edge of the left side plate. A keel weight is attached to the keel member. To cause the device to act in its second mode, a planer mode arm is removably attached to one of the side plates.

Abstract: A security strike plate comprising a strike plate portion adapted to receive a locking bolt and a security member. The security member includes a ceiling having an outer surface and an inner surface, an outer side wall extending downwardly from the ceiling, and a floor extending inwardly from the outer side wall. The ceiling is located in the same plane as the strike plate portion and is an extension thereof. The ceiling and the floor are substantially parallel. An inner side wall can extend upwardly from the floor substantially parallel to the outer side wall, the inner side wall having an outer end that abuts against the inner surface of the ceiling. The ceiling and floor having openings therein adapted to receive an elongated anchor member therethrough.

Abstract: A waterfall aquarium including an enclosed transparent water tank having an interior and exterior. A water exit conduit communicates the interior of the water tank with the exterior thereof. The water exit conduit includes a hollow tubular body having an exit end and an intake end, with the intake end thereof being located below the exit end. The water tank rests upon a base having an interior and an exterior. A water pump is located within the interior of the base. The water pump has an inlet and an outlet, the inlet communicating with the interior of the base and the outlet communicating with the interior of the water tank. A water receptacle is adapted to receive water from the water exit conduit and return the water to the interior of the base.

Abstract: A rear rack for a folding bicycle. The rear rack includes right and left chassis bars and a support platform positioned above the chassis bars. Rear support struts are pivotally attached at their upper ends to the chassis bars adjacent their outer ends, the support struts having lower ends adapted to be pivotally attached to the rear dropout of a folding bicycle. Forward support struts are pivotally attached at their upper ends to the support platform adjacent its inner end, the lower ends adapted to be pivotally attached to the rear dropout. The forward support struts are releasably locked to the chassis bars when the rear rack is erected for carrying a load. A rear support strut is pivotally attached to the chassis bars adjacent their outer ends, and pivotally attached to the support platform.

Abstract: A two-way motion sensor meter for measuring arm exercise. The meter is mounted on a wrist band adapted to be affixed to a user's wrist. The meter includes numeric display means driven by an electronic or mechanical system. The electronic or mechanical system includes first and second pendulums. The first pendulum is adapted to swing about an axis in a plane substantially parallel to a user's body. The second pendulum is adapted to swing about an axis in a plane substantially perpendicular to a user's body. Each pendulum is adapted to send a signal to the numeric display means each time it is caused to swing by movement of the user's arm upwardly and/or downwardly during exercise. The numeric display means is adapted to add each signal to provide a display of the total number of signals.

Abstract: A stub-out cover for protecting the outer surface of a stub-out line. The stub-out cover includes a substantially rigid, molded tubular member open at one end and closed at the other end. A plurality of flexible tab members extend from the inner wall of the tubular member inwardly toward the longitudinal axis of the tubular member. Each tab member has a height that is slightly greater than the distance between the inner wall of the tubular member and the outer surface of the stub-out to be protected. When placed onto a stub-out, the tab members bend to tightly engage the outer surface of the stub-out.

Abstract: A saliva ejector or eductor including an ejector tube having a suction end and a discharge end. The ejector tube has a wire embedded in the wall thereof adapted to allow the tube to be easily bent into a selected configuration and to retain that configuration. A hollow tip is secured to the suction end of the ejector tube. The tip has an upper face and a lower face. A plurality of tear-shaped openings extend solely through the upper face and communicate the interior of the tip with the exterior thereof.

Abstract: A cutting cup for a sphere making machine. The cutting cup includes a cylindrical ring having an outer wall, an inner wall, a bottom wall, and a top wall, the top wall having at least one beveled facet angled downwardly from the outer wall to the inner wall. A cutting element is attached to each of the beveled facets. Each of the cutting elements has a cutting edge adapted to at least partially contact a workpiece to be formed into a sphere. A mounting member is attached to the bottom wall of the cylindrical ring for attaching the cutting cup to the spindle of a sphere making machine.

Abstract: A fielding glove has an outer shell having at least one finger portion, a thumb portion, and a web joining the thumb portion and the nearest finger portion; a mitten compartment that holds all four fingers, positioned and fixed upon or within the outer shell at an angle of approximately 40 degrees in relation to the upright finger portion(s) of the outer shell of the glove, and a thumb compartment that is rotated forward in a approximately 20 degree arc from the plane of the finger portions of the mitten, and maintains a fixed angle between the thumb and index finger within said mitten of approximately 90 degrees. In addition, to accommodate the ergonomic alignment of the mitten portion, the entrance for the hand into the mitten compartment, on or within the glove must also align at the same approximately 40 degrees, from the upright “finger” portion of the glove.
