Abstract: Method and apparatus for the whiting of teeth includes a source of oxidizing gas and a handpiece for delivering the gas to a tooth. A cup attached to the handpiece is provided for receiving the gas and exposing a selected area of the tooth to the gas. The cup includes a resilient edge for sealably the edge for engaging the tooth around the selected area to prevent escape of a gas therepast.

Abstract: A method of treating gum disease, includes directing a stream of oxidizing gas onto human dental and oral conditions for a period of time sufficient to kill microorganisms within said inflamed human tissue.

Abstract: A reductant rinse including xylitol prevents buildup in ozone carrying lines in apparatus for the treatment of dental caries.

Abstract: Apparatus is provided for the sterilization of Prion infected surgical tools and the method for such sterilization includes disposing Prion infected surgical tools in the chamber, evacuating the chamber and introducing ozone into the chamber for a period of time sufficient to oxidize Prion amino acids. During this exposure the tools are agitated in order to insure all surface areas are exposed to the ozone. Following sterilization the ozone and sterilized tools are removed from the chamber.

Abstract: The present invention discloses both a method of operating CPAP apparatus, and the apparatus itself in which a breathable gas delivery device, or mask (1), is connected to a gas supply pump (14) via a conduit which includes a restriction to gas flow such as a small bore portion (3). A pressure transducer (11) is used to sense the gas pressure at the patient's nose and the transducer output is used to servo-control the pump (14) to maintian the sensed pressure substantially constant.

Abstract: This invention concerns the use of ozone in the treatment of dental caries.

Abstract: A protective varnish is provided for prophylactic treatment of exposed dentin. The varnish offers mechanical protection from wear and prevents hypersensitivity by blocking the dentin tubules. The varnish comprises a matrix of curable resins. These resins penetrate the dentin and after curing enforce it, making the dentin more resistant to abrasion. The varnish may also offer an antimicrobial effect. This effect can be achieved by the varnish containing a broad spectrum antimicrobial agent such as 2,4,4′-trichloro-2′-hydroxydiphenyl ether.

Abstract: A combination mouth and nasal mask (40) for assisted respiration or CPAP is disclosed.The combination mask (40) has a frame (42) to the rear side of which is mounted a separate nasal cushion (44) and mouth cushion (46). Both the nasal cushion (44) and the mouth cushion (46) separately form a rolled edge seal around the patient's face in the vicinity of the nose and in the vicinity of the lips. Inlet air is communicated from within the housing (48) to the mouth chamber, circumscribed by the mouth cushion (46) by means of one or more interconnecting tubes (62).The proportion of air communicated to the mouth chamber (48) is controlled by the sizing and number of the tube(s), thus providing for free flow of air, restricted flow of air and pressure equalization, or zero flow of air.A mouth mask (10) for assisted respiration or CPAP also is disclosed.

Abstract: A miniature spring socket having a plastic housing containing the contact which comprises a pair of facing beam-like spring contacts which receive a terminal post therebetween. The plastic housing has slots behind the beam-like contacts to permit such beam-like contacts to be deflected back into such slots, and thereby accommodating terminal posts having large variations of diameters. The two beam-like contacts are secured to a ring-like base to which a third leg is also secured. Such third leg is bent over the rim of the housing and extends down the outside of the housing beyond the end thereof to form a tab which can be soldered to a conductive pad on the bottom side of the printed circuit board in which the mini-spring socket is installed.

Abstract: A metal clip for connecting an insulated wire and a terminal post together without stripping the wire or solder. The clip is generally channel-shaped with a first slot means extending across the bottom wall of the channel and into the side walls of the channel. Extensions of the free end of the side walls are folded within the channel back towards the bottom wall and have second slots formed therein which are aligned with the first slot means. The conductor is inserted into the first and second slots and then the terminal post is pushed into the channel at right angles to the wire and adjacent the bottom wall thereof to force the conductor farther back into the slots and causing the edges of the slots to either grip or cut through the insulation and into the wire, thereby making a good electrical and mechanical connection.

Abstract: An elongated bus bar is coated with solder and has a first plurality of large holes, and a second plurality of smaller holes formed therein. The holes are spaced apart predetermined distances which correspond to the distances between terminal posts upon which the bus bar is to be mounted. The larger holes are sufficiently large to remain completely free of the bus bar and also of the solder when it is melted. The smaller holes lie individually in sections of the bus bar which are bent in opposite rotational directions with respect to the main plane of the bus bar, and about the longitudinal axis of the bus bar, to provide an interference force fit between each of the smaller holes and the terminal posts inserted therein. These force fits oppose each other in different terminal post insertions because of the bending of the bus bar around the smaller holes.
