Abstract: A retractable wheel assembly, housed in an inverted well, has an elongated arm mounting wheels, is pivotally mounted in the well and is pivotally movable manually between a retracted position by which the arm is releasably locked interiorly of the inverted well and an extended operative position by which the arm is releasably locked with its wheels exposed. The arm has spring-biased detents for such manipulatively releasable locking engagements with detent recesses for both positions. Wheel assemblies in bottom rear-corner wells of a suitcase allow "wheel-barrowing" movement of the suitcase. Wheel assemblies in the bottom inverted wells at all four suitcase corners allow "trolleying" movement of the suitcase.

Abstract: A stairwell, in a split or multi level home provides access to and air communication with lower-level, mid-level and upper-level rooms, resulting in a chimney effect of continuously drawing higher temperature and highest temperature room air from the lower-level room. Vertically directed downward axial fans of a room-air interceptor device, emplaced in the lower-level room at its ceiling and at its entrance to the stairwell, not only eliminates such chimney effect; but also intercepts and recirculates temperature-layered room air in the lower-level room, resulting from gravity circulation, to dissipate such temperature-layered room air to render the room air temperature in the lower-level room more uniform and, hence, more comfortable for human habitation and enjoyment.

Abstract: The vehicle window cleaning device replaces the windshield wipers. The device employs two electrically powered high-speed blowers, with high-impact exhaust air ducted to air nozzles to clear rainwater, water, moisture, debris and loose powder snow from the exterior surfaces of the windshield, right-side and left-side front and rear window, and the rear window, and from the mirrored surfaces of the right and left side view mirrors. One blower services the windshield, the right and left side-view mirrors, and the right-side and left-side front windows. The second blower services the rear window, and the right-side and left side rear windows.

Abstract: A paste wax applicator has a handle carried proximally on an elongated housing, allowing a human operator to remain in a non-fatiguing upright position by having one of his hands hold the handle and the other cradle the elongated housing, while applying to a floor surface paste wax dispensed from a cartridge tube. A plunger and the cartridge tube are housed by the elongated housing. The human operator actuates a cartridge-gun mechanism operatively connected via the plunger to the cartridge tube to incrementally drive the plunger, thereby causing paste wax to be dispensed from the cartridge tube for application upon the floor surface of the floor to be waxed.

Abstract: A room humidifier in combination with a source of potable water and a source of heated fluidic material, such as a room hot water radiator, room steam radiator, room baseboard convector, remote steam boiler or remote hot water boiler. Potable water from its source is supplied to cover a heat exchanger in the humidifier to a desired level. Such potable water is heated by the heated fluidic material flowing through the heat exchanger, causing the formation of water vapor which collects within the humidifier. The desired relative humidity in the room is attained and maintained by control means which causes the flow of the heated fluidic material through the heat exchanger to form such water vapor and the control means causes a fan to operate to draw room air through the humidifier to render such room air moisture-laden and to blow such moisture-laden air into the room.

Abstract: A combined portable animal waste and training device whereby a pet's owner, by means of the device's training structure, can induce, teach and train the pet to eliminate its urine and feces upon the device's animal waste structure being operatively emplaced relative to a toilet bowl of a standard toilet having a toilet tank and followed by the sequential operation of the animal waste structure in depositing the urine and feces eliminated by the pet and disposed in the toilet bowl, followed by cleansing action and then followed with the flushing of the toilet tank to flush down such urine and feces in the toilet bowl.

Abstract: The vehicle window cleaning device totally replaces the windshield wiper system. A combined housing houses an electrically powered blower and heater. The housing is ducted to air nozzles disposed below the windshield's bottom. Blower-forced air from the housing through the air nozzles impacts the entire windshield exterior with tremendous force to clean such surface by instantly blowing away dirt, water and moisture. High-temperature air heated by the heater and blower-forced through the air nozzles likewise impacts, melts and blows away ice, ice-encrusted snow and snow from the windshield's exterior surface and cleans such surface by blowing away dirt, water and moisture.

Abstract: A removable straw cover that is sterile in combination with a sterile drinking straw protects the drinking straw against bacterial contamination. A line of circumferential indentations separates the straw cover into a upper proximal portion and a remaining distal portion. Separation along such circumferential line of indentations is effected by grasping closed ends of the straw cover and longitudinally extending the straw cover along its longitudinal axis.

Abstract: A portable animal waste device for use in conjunction with a standard household commode is described. A support structure, mounting a pivoting platform and emplaced over a toilet bowl, is connected to the toilet's flush mechanism. The platform pivots between a lowered position for animal access upon the platform and a raised position following animal exit from the platform. The platform in its raised position forms a washdown enclosure with the support structure. When the platform is in its raised position, the washdown enclosure is washed down and the waste is disposed of by a flushing action. A sensing and electronic control system is provided to activate flushing action only when the animal has exited the platform for a predetermined period of time.

Abstract: A shower curtain support has a shower curtain rod mounted by opposing wall brackets on parallel end walls of a shower stall. The rod slidably suspends a conventional shower curtain across the front opening of the shower stall. Spiders on the terminal ends of the rod are indexably received by spider plates of the wall brackets to dispose the rod in a number of radial orientations relative to the wall brackets. In another embodiment for infinite radial orientations of the rod within the full range of 360.degree., outturned flanges on the rod ends, sandwiched between inturned flanges of compression nuts and closed ends of threaded studs projecting from wall brackets, allow such infinite radial orientations of the rod relative to the wall brackets.
