Abstract: A device for use by a person wearing a colostomy, ileostomy or ureterostomy bag which protects the bag from binding by clothes and being noticed as readily by others. The device is a semirigid guard worn by the person below the stoma at the level of his or her waistband or belt line. The inner portion of the guard conforms to fit snugly and comfortably against the person's body. The outer portion of the guard is semirigid and curved to permit the waistband of the person's clothing to fit smoothly around the guard. The inner and outer portions may be separate pieces, removably attached to one another, as with hook and loop fasteners. Between the inner and outer portions of the guard is an opening through which the bag hangs freely. The outer portion may extend up to a level so that it covers and protects the stoma.

Abstract: A device for converting power or hand drills to drive sockets. The cylinder of the device attaches to the drill in place of the chuck, or, with an adaptor, as a bit would fit in the chuck. The cylinder also houses the known, toothed gear assembly which drives the socket. The cylinder is surrounded by a slidable ring and pierced by a push rod attached to opposite sides of the ring. The ring and push rod are pushed forward, and the push rod activates the release mechanism of the gear assembly.

Abstract: A mounting device for hanging window shades hinged along its length, and its opposite edge clamping the top margin of material of the shades in place. A series of channels on the bottom of the mounting device extend the length of the mounting device. Cord guides are suspended below the mounting device and are slidably attached to the mounting device in the channels. The cord guides can be moved to the desired locations on the mounting device and secured in place. The mounting device is attached to the wall with brackets into which the ends of the mounting device are seated.

Abstract: An air lock for injecting a fibrous or granular material, such as insulation, into an airstream. The air lock has two counter-rotating, generally cylindrical rollers in facing contact with each other along their edges, made of a resilient material such as a closed cell foam. The rollers are also in facing contact with the outside of a tube or cylinder through which the airstream flows. The insulation is positioned on top of the rollers, and the rollers feed the insulation between them and into the airstream. The contact between the rollers and between the rollers and the injection tube create the air lock between the airstream and the atmosphere. The invention can also be used in a vacuum machine, particularly suited for vacuuming and collecting fibrous or granular materials.
