Abstract: A dental flossing apparatus having a body with extending retention arms configured for retaining a length of dental floss under tension between the arms. The tension is applied between resilient arms and biased into tension by means of legs coupled to said arms which are manipulated and optionally locked together. By way of example, a bore extending into the bead may be engaged over a post extending proximal the end of the retention arms. Other forms of engaging the floss with the ends of the retention arms are also described. The body of the flossing device or the beads may be configured in the shape of animals, action figures, characters, or other objects to enhance entertainment value. Floss for the flossing device comprise short sections of floss with a bead near each end, which may be separated from a roll of floss upon which a plurality of beads are affixed.

Abstract: A lightweight face shield which protects the face of the wearer from debris and/or hazardous materials, such as biological materials, and is particularly well suited for medical and dental applications. The face shield utilizes a two-piece tiered structure with a preferably canted retention frame joined through an inclined structure member to a shield frame member below which is retained a transparent shield, and above which a minishield. The shield frame member is retained forward of the retention frame member so as to retain the peripheral portions of the shield separated from the face of the user, providing improved ventilation and reduced fogging of the transparent shield. A trampoline style support arm is described that provides solid retention, compliant comfort, and reduced material requirements. Optional locking hinge assemblies for the support arms and a nose bridge are also described.

Abstract: A ventilated face shield assembly with a glare shield which protects the face of the wearer from debris and/or hazardous materials, such as biological materials, and is particularly well suited for medical and dental applications. A ventilated headband is used as a spacer and to support the face shield assembly on the face of the wearer. The glare shield and face shield are made of sheet material and are configured for flat storage. In one embodiment, the glare shield and face shield are coupled with a hinge and a flexible cord retains the glare shield and face shield in an arcuate configuration. In another embodiment, a protective breathing mask is attached to the face shield assembly and supports the glare shield and face shield. In a further embodiment, the glare shield is used as the spacer for the face shield.

Abstract: A portable crimping apparatus suitable for crimping hose fittings on high capacity hoses having four to six layers of braided wire reinforcement utilizes a relatively light weight pusher which has openings therethrough to illuminate the crimping operation. The pusher is mounted on a plate attached to a ram of a hydraulic cylinder, which ram is used to advance the pusher. The pusher is retained in position on the plate by thumb operated spring latch. A pair of lifting arms are pivoted to a support for the ram to facilitate carrying the portable crimper apparatus.
