Abstract: The present invention relates to methods and compositions for reducing, inhibiting, and/or preventing, calculus, tartar, plaque, and/or microbes, in the oral cavity, comprising from about 15% to about 70% of an alkyl vinyl ether maleic copolymer or terpolymer denture adhesive component, an effective amount of a quaternary ammonium antimicrobial agent selected from the group consisting of cetylpyridinium chloride, domiphen bromide, and mixtures thereof, and a non-aqueous vehicle. A denture wearer in need thereof applies the composition to the oral cavity and/or the denture prosthesis and thereafter secures the denture to the oral cavity.

The denture care composition may further comprise a denture care carrier. Kits comprising polybutene, a container and instructions for use or an applicator for applying the composition directly to the denture surface are also disclosed. The polybutene composition of the kits can further comprise a denture care active.

Abstract: In a wireless communication system having sometimes mobile subscriber units and a plurality of fixed network devices located at cell sites, a multimode acquisition protocol is provided at each subscriber unit which first senses whether the subscriber unit is static or mobile from the nature and quality of the communication links with nearby network devices and then enables an acquisition protocol suited to either static mode or mobile mode. In a specific embodiment, the protocol initiates procedures to change acquisition mode from static to mobile upon failure of the subscriber unit to sense three consecutive scheduled polling packets sent by a linked network device or upon loss of communication with any locally-known network device or upon failure to transmit 25 consecutive data packets. In such case, the procedure is initiated to determine whether it is appropriate to switch to a mobile mode for purposes of acquisition.

Abstract: Chewing gum and confection compositions that inhibit the buildup of plaque and other debris on teeth, comprising polybutene with a molecular weight of 300 to about 3000. Upon its release from the gum or confection piece by chewing or dissolving the polybutene forms a protective coating on the hard tissue surfaces of the oral cavity and may, optionally, provide sustained release of a cosmetic and/or therapeutic active ingredient to deliver prolonged therapeutic, prophylactic and/or cosmetic benefits.

Abstract: Systems for delivering cosmetic and therapeutic actives to the oral cavity employ a strip comprising a first layer of material, a second layer comprising polybutene with a molecular weight of about 300 to about 3000, and a cosmetic or therapeutic active included within the second layer. Therapeutic and cosmetic actives in compositions comprising polybutene inhibit or prevent gingivitis, caries, staining, fungi, bacteria and plaque build-up in the oral cavity by means of the delivery system.

Abstract: An integrated communications system. A substrate having a receiver disposed on the substrate for converting a received signal to an IF signal, a digital IF demodulator disposed on the substrate and coupled to the receiver for converting the IF signal to a demodulated baseband signal, and a transmitter disposed on the substrate operating in cooperation with the receiver to establish a two way communications path.

Abstract: An electrical apparatus comprising first and second PTC elements composed of a polymer composition with conductive particles dispersed therein, an insulating body, and first and second conductive terminals. Flexible conductive members having a first end that can be electrically connected to a source of electrical power and a second end that is adapted to receive and make electrical contact with the apparatus are provided. The PTC element and the insulating body are positioned between the first and second conductive terminals so that when the apparatus is inserted between the flexible conductive members, the members exert a pressure on the insulating body.

Abstract: A method of electrowinning a metal by electrolysis of a melt containing a dissolved species of the metal to be won using a non-consumable anode having a metal, alloy or cermet substrate and an operative anode surface which is a protective surface coating of cerium oxyfluoride preserved by maintaining in the melt a suitable concentration of cerium, is characterized by using an anode provided with an electronically conductive oxygen barrier on the surface of the metal, alloy or cermet substrate. The barrier layer may be a chromium oxide film on a chromium-containing alloy substrate. Preferably the barrier layer carries a ceramic oxide layer, e.g. of stabilized copper oxide which acts as anchorage for the cerium oxyfluoride.

Abstract: Transition metals of the groups IVB, VB and VIB or alloys thereof with Al are electrodeposited in a system of an electrolyte based on an aromatic hydrocarbon. The electrolyte is originally prepared by dissolving 0.02 to 0.2 moles of an inexpensive high oxidation state transition metal halide and 0.2 to 0.5 moles AlBr.sub.3 in 1.00 mole of the aromatic hydrocarbon. Additions of transition metal powders or Mg or Al particles lead to the pre-reduction of the high oxidation state transition metal ions to lower oxidation states. Alkali metal or Mg halides may be used to establish favorable bath conditions. The electrolysis is carried out with dissolvable metal anodes, to maintain the bath composition. The plating current density, bath composition and method of preparation are chosen to obtain the desired composition of the coatings.
