The top layer may also be welded to the backing layer within the peripheral outlines to create inflatable subenclosures to give the applique a sculpted appearance.

Abstract: A woman's shirt that is normally of hip length and is convertible into a shirt of waist length that in a first wearing mode has an underlying halter integral therewith, and in a second wearing mode an overlying halter. The shirt front is defined by left and right panels that can be buttoned together or left open, the back being of greater length to form a rear section that extends below the front. Extending across and normally covering the rear section is a fabric band whose ends are sewn to corresponding ends of the rear section and whose upper margin is joined by releasable fasteners to the lower margin of the left and right panels, the lower margin of the band being free. Complementary components of a connector are attached to the lower left and right corners of the band. To convert the shirt to the first wearing mode, the wearer releases the band from the panels, and then raises the band under the panels and over her head, thereby causing the band to yoke the neck of the wearer and to cover her bust.

Abstract: A rechargeable self-contained deodorizing toilet seat is provided for installation on any standard toilet to remove bathroom odors. The seat is substantially the same in size and appearance as a standard toilet seat. Air conduits pass though the right and left sides of the seat member from the lower surface to the outer surface. The conduits contain activated carbon air filtration media and blowers for moving the air. Seals on the lower surface seal the seat to the toilet rim except at the front where ducts are provided for the introduction of fresh air. Lips on the inner edges of the ducts deflect air down into the bowl. The blowers are rotated by direct current electric motors powered by rechargeable batteries. Operation of the motors is controlled by switches which close only when the lid is raised and weight is placed on the seat. An electronic timer turns off the air filtration system after a preset period of time to conserve the battery power.

Abstract: A control system for hydro-massage tub systems in which water is circulated through a pump and heater from the tub back to a plurality of jets in the tub to create a turbulent massaging action. The system is comprised of an activating device, a pump, a switch activating circuit, a heater with proportional control and a water level sensing safety system. The pump is controlled by a switching and timing circuit that limits the time the pump is on which is slaved to a heater control circuit to prevent operation of the heater unless the pump is circulating water. The proportional heater control circuit maintains the water temperature within a degree or two of a preset temperature by proportionally reducing power as the temperature approaches the preset limit. The activating device transmits a ignal to the switching and timer circuit when a mechanical plunger isolated from electrical circuits is operated.

Abstract: This is an improvement in the way to inflate and deflate a doughnut-shape cushion device by doing it automatically. The electronic circuits of the device are activated by a user through a normally open momentary switch. This action turns on an electrical pump to start blowing air to the cushion and at the same time a solenold exhaust valve shuts off. This rubber cushion, attached to the underwear of a person, is inflated to a pressure pre-established in the microcomputer. The pressure sensing element monitors the changes in pressure inside the cushion. As long as the person wearing the cushion is seated, the computer maintains the solenoid exhaust valve closed. Once the person stands up, the pressure inside the cushion drops below the pre-established valve and then the microcomputer output voltage decreases to 0; the exhaust valve opens and consequently the cusion deflates. Later on, the cycle can be repeated by pressing the switch again to initiate the sequence of operations.
