Abstract: The present invention provides processes by which a polymeric hydrogel can be securely adhered to a substrate to form a hydrogel laminate with greatly improved delamination resistance. The laminate is formed by casting onto a polymeric adhesive-coated substrate an aqueous solution of hydrophilic polymer, then exposing this composite to ionizing radiation which cross-links the hydrophilic polymer to form a hydrogel and also induces copolymerization of the hydrophilic polymer and the adhesive polymer.

Abstract: A shampoo that contains ketoconazole, a surfactant, a foaming agent, thickener sufficient to give the final formulation a viscosity in the range of about 4,000 to about 9,000 cps at room temperature (i.e., about 20.degree.-25.degree. C.), preservative, butylated hydroxytoluene or butylated hydroxyanisole in an amount sufficient to retard degradation of the ketoconazole, and acid, base or buffer sufficient to give the final composition a pH in the range of from about 4 to about 10.

Abstract: Brushhead magazine for receiving a number of brushheads (22), comprising a plurality of containers, which lie parallel alongside one another in mutual separation, in each case fully enclose a brushhead (22) and the height of which is dimensioned to correspond approximately to the width of a brush base (26) of each brushhead (22), a coupling end of the brushheads (22) in each case facing towards the container opening (30). A wall exhibits, in the area of each container opening (30), a closing flap (32) made from dimensionally stable material, which closing flap is defined by a target rupture line (36) and a hinge (40), formed by an attenuation line (38). The closing flap (32), as its target rupture line (36) is destroyed, can be pivoted by means of the coupling end of a brush handle about the hinge (40) into an open position in the interior of the assigned container. In each container there is disposed a locking device, by means of which the closing flap (32) can be locked in its open position.

Abstract: Novel sunscreen compositions containing titanium dioxide having a particle size less than about 35 m.mu. and zinc oxide having a particle size less than about 50 m.mu. are described as well as methods of protecting the skin from damaging ultraviolet radiation.

Abstract: A toothbrush having a non-slip region on its handle to facilitate better manipulation of the brush is disclosed. An insert having a surface with raised ribs is formed in a separate molding operation and then inserted within an aperture formed in the toothbrush handle. A method for manufacturing the toothbrush is also disclosed.

Abstract: In the case of a holder for a toothbrush, which holder comprises a plate (1) to be attached to a wall and a holding element (7) extending, in the usage position, perpendicular to the plate, the plate (1) and the holding element (7) are pivotably connected to each other and there is provided, moreover, on the plate (1), a suspension device (3), in which a magazine (10) containing accessories for the toothbrush can be suspended. When the holding element (7) is pivoted out of the open position into the usage position, the holding element (7) grips over the suspension device (3) in such a way that the magazine (10) is protected against unintended detachment from the holder.

Abstract: A buccal tube contains a rotating integral cover attachable over the archwire slot of the tube.

Abstract: A dental bracket is described which comprises a non-metallic bracket, typically formed from a transparent crystalline alumina. To this non-metallic bracket there is bound a stainless steel metallic foil mesh pad which is adhesively connected to the dental bracket. The foil mesh pad can thereafter be bound to the tooth using typical adhesives, and without worrying of bonding or debonding associated with ceramic or crystallic brackets. If desired, one can make the stainless steel pad aesthetically pleasing, to obtain further aesthetic benefits from this device.

Abstract: A metal bracket is provided with a covering formed for dental porcelain. The porcelain is placed on the sides and buccal surfaces of the bracket and provides for an aesthetic appearance to the bracket. However, the high strength is provided by the metal. The exposed metallic surfaces of the archwire slot and base enable the bracket to function in the manner of a metal bracket. This porcelain fused to metal bracket enables the user to derive the best possible functions of both types of materials.

Abstract: The present invention relates to a feeding-bottle device with an adjustable air inflow, comprising a feeding bottle, a teat and a clamping ring for securing the teat to the feeding bottle. A plurality of ribs are disposed on the annular collar of the teat or the rim of the feeding bottle. The spaces between these ribs form air-inlet passages. Each rib has an interruption located opposite an annular moulding disposed on the flange of the clamping ring. By screwing the clamping ring onto the feeding bottle to a greater or lesser extent, the effective cross-section of the air-inlet passages can be adjusted as a result of a lever effect exerted between the moulding and the ribs. Leaks of the liquid contained in the feeding bottle can be prevented by tightly securing the clamping ring to the feeding bottle.

Abstract: A medical dressing comprising an embossed, thin polymeric film coated on one side with a medical grade, pressure-sensitive adhesive. The embossed film has a low coefficient of friction, preferably less than about 0.6, on the outer adhesive free surface which makes the film particularly resistant to unintentional removal by rubbing forces. The film is intended primarily for use as a blister dressing, but may also be provided with an absorbent pad for use as a wound dressing.

Abstract: A dental bracket with a T-shaped archwire as described. In addition, it is possible to have a pair of tie wings which lock around the archwire so that the size of the archwire can be reduced, as well as the size of the dental bracket.
