A massage device consisting of a plurality of rollers having projections, the rollers being mounted for rotation on a carrier, rotation occurring when the rollers are placed in contact with a portion of the body to be massaged and the carrier is moved in a direction normal to the axis of rotation of said rollers, the said projections preferably being of resilient material although firm enough to press into the fleshy and muscular portions of the body to produce massaging action when reciprocated...

A massage wheel consisting of a cylinder having a plurality of prongs protruding from its circumference to which is attached an axle on either end which serve as handle grips for manipulation of the wheel over the body surface for massage purposes.

A process of supplying fluoride to teeth comprising applying to the teeth a source of fluoride ions and an orthophosphoric acid solution having a pH of about 3-4, then neutralizing the pH to about 7 with an aqueous neutralizing solution containing calcium ions and phosphate ions, wherein there is present about a stoichiometric amount of the phosphate ions relative to the calcium ions, the neutralizing solution having a pH of about 7.

Dental preparations containing materials having calcium and phosphate components are described. Such materials are typically fluorapatite, fluorohydroxyapatite, hydroxyapatite prepared by alternately changing the pH from about 7 to about 4 to about 7 several times, including such materials which have incorporated therein ions such as monofluorophosphate and carbonate or divalent ions such as zinc or fluoranions of a metal such as zinc, e.g. ZnF.sub.4.sup.-2.

An exerciser and body massage device for massaging and kneading the torso or any appendage thereof by means of resilient rollers carried by a frame comprising opposed, rigid, U-shaped units with at least a pair of rollers rotatably mounted on the bow of each unit and having the ends of the legs telescoped and normally urged by spring means to apply a massaging pressure to the body when manipulated. The telescoped portions of the units provide parallel hand grips for manipulating the device.

A bacteria filter for use in anesthesiology and respiratory care systems to filter fluid flow at a desired point in a system. The filter includes an enlarged non-conductive, transparent tubular housing having a passageway therethrough and tapering at one end to a reduced tip. A conductive connector is mounted to the reduced tip and a conductive end cap is affixed to the end of the housing distal from the reduced tip. The end cap has an opening therethrough terminating in a projecting connector. ...

An oral composition comprising (i) at least one phosphate selected from the group consisting of linear polyphosphates of the formula (I): wherein M represents Na or K and N .gtoreq.2, and cyclic polyphosphates of the formula (II): wherein M' represents Na or K and m.gtoreq.3 and (iii) l-menthol, anethol, or the mixture thereof in an aqueous medium. This oral composition has an excellent antibacterial effect and prevents the development of calculus and periodontal diseases.

A body massager including a frame which extends about a user's body and is movable upwardly and downwardly relative thereto, and carries a series of circularly spaced rollers for contacting and massaging the body, with the rollers being spring urged inwardly against the body to follow its contours.

A reducing roller device consisting of a tubular member of yieldable material having the end portions thereof supported between a pair of flat discs mounted for rotation about a shaft extending axially of the tubular member and terminating in a pair of handles at opposed ends thereof outwardly of the respective discs. A modified embodiment provides that the tubular member form a closed sealed chamber between the discs with an entrance to the chamber being provided by one of the discs so that wat...

A machine for moving a massaging roller lineally along a path beneath a sheet of material which covers an elongated slot in a table or cabinet top, which table or cabinet is usually covered with upholstery material, and overlies a sheet of material which may be urged upwardly against the upholstering material and the spinal area of the person lying on the table to be massaged, when the machine is in operation. The roller is moved substantially the length of the spine, in a timed sequence and und...
