Abstract: Dental mirrors are described that by virtue of their design and configuration are self-drying and have the capability of retracting the cheek away from the teeth being examined or worked on by the dentist, all with comfort for and safety to the patient. The mirrors have clips or the like to detachably secure an absorbent roll thereon. The absorbent roll, such as a cotton roll commonly used in the practice of dentistry for absorbing fluids from various regions of the mouth, is preferably positioned and secured in a substantially tangential position relative to a circular or elliptically-shaped mirror. This tangential position in turn may be varied relative to the longitudinal axis of the elongate handle of the dental mirror, since the mirrors can be used for viewing and absorbing fluids from any region of the mouth.

Abstract: An adjustable small parts holder especially useful in the manufacture or repair of jewelry is described. The device includes a body having at its upper portion two or more moveable jaws. The jaws have inwardly projecting upper end portions and are convergeable toward a common center external to the body. A linear supporting member such as a cylindrical rod is disposed along the longitudinal axis of the body, the upper end portion of this member being moveable upwardly toward the common center. A mechanism such as a rotatable collar is provided for moving the moveable jaws inwardly to cause their inwardly projecting upper end portions to converge toward the common center. In addition, a mechanism such as an adjusting screw is provided so that the upper end portion of the supporting member can be moved toward or away from the common center.

Abstract: The knob of a handpiece for use in a push-pull type electric lighter is provided with an increased diameter portion positioned in closer proximity to the ignition end than the handle portion of the knob. At least one O-ring or like seal is mounted around the periphery of the increased diameter portion of the knob. The outer end of the socket which protrudes through an aperture in a panel, and the portion of the handpiece extending out from the socket when fitted into the socket are encased (except for the handle portion of the knob) in a hollow open-ended tubular housing mounted on the face of the panel. The O-ring of the handpiece is adapted to engage the interior wall of the tubular housing and form a water-tight, slidable seal therewith yet permit the handpiece to be pushed into and be pulled from the socket by means of the handle portion of the knob. The portions of the socket extending to the rear of the panel may be, and preferably are, encased by another housing.
