Abstract: A plunger type electromagnetic relay includes a contact spring provided with a moving contact at one end thereof and having the other end rotatably fitted to a terminal, and the contact spring is further provided with a projection on the central portion thereof. When an electromagnetic coil is not energized, the projection on the contact spring is urged downward by the bottom portion of an operating rod attached to the lower portion of a movable core, thus establishing a normally-open condition. When the electromagnetic coil is energized, the movable core is moved upward and consequently the bottom portion of the operating rod and the projection of the contact spring are also moved upward in their engaged condition. When this occurs, an electric connection is completed between the moving contact at one end of the contact spring and a fixed contact provided in a relay housing.

Abstract: An improvement in an otic prosthesis of the type used in ossicular reconstruction of the sound-conducting mechanism of the middle ear is provided. The improvement comprises a movable joint which connects a head portion and a shaft portion whereby there is provided a flexible, variably angled prosthesis, which can be readily set in position in the middle ear against the tympanum during surgical implantation. The movable joint permits the so-connected shaft portion to move in at least a single plane normal to the head portion and can itself be readily set against either retained bony elements of the sound-conducting mechanism or against tissue grafted into the aperture (oval window) between the middle and the inner ear. The movable joint is responsive to tympanic vibrations and the prosthesis exerts a minimized pressure on the tympanum during surgical implantation and thereafter it also resists dislodgment within or extrusion from the middle ear.

The prosthesis comprises a surface adapted to be fixedly attached to bone and bears a polymethylmethacrylate film upon the attachment surface. The polymethylmethacrylate film is adhered to the prosthetic element by a process which comprises treating the prosthetic element surface to eliminate any weak boundary layer, applying polymethylmethacrylate to the treated surface, and thereafter annealing the polymethylmethacrylate film.

Abstract: The combination of a passive dosing dispenser, of the type having a reservoir containing a cake of active ingredients which are depleted as water is routed through the dispenser, and an improved hypochlorite cake for use therein. The improved hypochlorite cake provides water-soluble hypochlorites, and additionally contains materials capable of forming a water-insoluble matrix from which hypochlorite salts may be leached out by the water in the reservoir. The size of the cake desirably increases somewhat while the dispenser is in use so that the mass of aqueous hypochlorite which may be poured from the reservoir of the dispenser remains constant or slightly decreases as the active ingredients are used up.

Abstract: A disconnect unit for the isolation of the aqueous contents of a swimming pool from pump lines running into said pool which permits contained water to be blown clear of said pump lines without need to remove any substantial quantities of water from the pool. The unit comprises a pool inlet fitting having a check valve permanently mounted therein and adapted to have inserted within the check valve at its distal end a compressed air nipple and at its proximal end frictionally and permanently embedded into the wall a blocking membrane for the inlet fitting member. The device functions by the first insertion of the compressed air nipple 1 into the check valve 2 and the locking of the shoulders of the two members together. The air line to the pump is then blown clear of water.

Abstract: A foam bathing apparatus comprising a main body including a blower, a container mounted on the main body for containing a bath and a porous body disposed at an inner bottom portion of the container.

The second buoyancy or lift structure is further equipped with identification and/or other types of sensors.

Abstract: Thick floatation pads for securement within the walls of floatation garments, such as life-saving vests and the like, are formed of stacks of aligned, relatively thin, flexible, resilient, foamed plastic sheets which are secured together along at least one edge. The sheets are substantially free of securement, one to another, between their edges. Thus, the sheets may relatively flex, move and bulge relative to each other for closely and comfortably conforming to the shape of the wearer's body and for tending to maintain maximum floatation volume at all times.
