Abstract: The present invention discloses an energy conserving thermostat for controlling the supply of energy within a commercial or industrial building during unoccupied periods and for providing additional energy to the building when required. The present system includes: a night thermostat for establishing a low temperature necessary for the maintenance of the building during a non-occupancy period; a seven-day timer clock calibrated for every hour of each day, with manually adjustable pins on the clock settable for a time interval within each day during which a normal comfort condition is required; mechanical switch means responsive to such pins of the clock; electrical switch means including a relay energized by operation of the mechanical switch; and an override timer including a time meter and a manually operable switch to increase the time setting for any day wherein an unusual supply of energy is required within a zone of the building. The extra time of such setting is recorded on a time clock meter.

Abstract: An oral composition is disclosed containing an effective auticalculus amount of a copolymer of glutamic acid, tyrosine and optionally alanine.

Abstract: An antibacterial oral composition effective to promote oral hygiene containing an antibacterial antiplaque agent and an additive which reduces staining of dental surfaces without substantially diminishing the antibacterial and antiplaque activity of the agent. Bis-biguanido hexanes, such as chlorhexidine and alexidine, and quaternary ammonium salts, such as benzethonium chloride and cetyl pyridinium chloride are typical examples of antibacterial agents. The antistain additive is a copolymer of glutamic acid, tyrosine and optionally alanine.

Abstract: A toothpaste composition comprising a vehicle containing about 45-80% by weight of liquid phase, comprising up to about 35% by weight of the toothpaste of sorbitol and at least about 25% by weight of the toothpaste of water and a solid phase including about 3-10% by weight of the toothpaste of gelling agent comprising at least about 3% by weight of the toothpaste of polyvinyl pyrrolidone as an agent to reduce drying and tube plugging.

Abstract: An additive, 0.05% to 5% of phytic acid, a chelator, unlike other chelators such as tartaric acid or ethylene diamine tetra acetic acid, prevents or reduces color fading of from 0.0007% to 0.5% of a water-soluble non-toxic red or yellow monoazo or blue triarylmethane dye-colored visually clear dentrifice containing both alkali metal monofluorophosphate in an amount to provide from 0.01% to 1% of fluorine and from 5% to 50% of a selected siliceous polishing agent having an index of refraction between 1.44 and 1.47, in a liquid vehicle having an index of refraction matching that of said siliceous polishing agent.

Abstract: A card holder comprising a single-piece transparent material having a rear face and folded therefrom and in close proximity thereto a front face; and projecting from the end of one of said faces a section of said transparent material adapted to engage with the body of camera. The projecting section typically may have a hole into which a tripod or camera case screw can be placed or may slide into an accessory shoe or flash attachment shoe.

Abstract: Dental cream having a smooth texture with little tendency to form grain containing calcium carbonate polishing agent and sodium lauryl sulphate surface active agent having a broad distribution of alkyl groups containing 10-18 carbon atoms and as additive which reduces grain and alkali metal pyrophosphate or an anionic phosphate mono- and di-ester mixture.

Abstract: A dentifrice of high viscosity wherein a water-absorbent anionic polyelectrolyte polymer, such as a polyacrylate, having at least one polyvalent cation, such as aluminum, and having a particle size less than about 74 microns, is employed as gelling agent and also effects the principal humectant function of the dentifrice vehicle.

Abstract: A periodontal dental composition is disclosed comprising folic acid and a polishing agent which is principally dicalcium phosphate.

Abstract: An antibacterial oral composition effective to promote oral hygiene containing an antibacterial antiplaque agent and an additive which reduces staining of dental surfaces without substantially diminishing the antibacterial and antiplaque activity of the agent. Bis-biguanido hexanes, such as chlorhexidine and alexidine, and quaternary ammonium salts, such as benzethonium chloride and cetyl pyridinium chloride are typical examples of antibacterial agents. The antistain additive is a peroxydiphosphate salt, preferably tetrapotassium peroxydiphosphate (K.sub.4 P.sub.2 O.sub.8).

Abstract: An oral composition containing an oral vehicle, tranexamic acid as antigingivitis agent, a fluorine-containing anticaries agent, and a flavor mixture of methyl salicyclate, menthol, eugenol and cineol.

Abstract: An oral composition adapted to inhibit symptoms of gingivitis, especially gingival bleeding, comprising an oral vehicle and effective amounts of tranexamic acid and folic acid.

Abstract: An opaque extrudable toothpaste containing as the abrasive and/or polishing agent a major proportion of sodium aluminosilicate and a minor proportion of another abrasive which is wholly or predominantly a soft abrasive such as dicalcium phosphate, in a vehicle which is wholly or predominantly water.

Abstract: A dentifrice containing a siliceous polishing agent and an alkali metal fluoride or monofluorophosphate, a dye and an additive which prevents or reduces color fading which additive is benzoic acid and/or phytic acid when alkali metal monofluorophosphate is present and which is benzoic acid when alkali metal fluoride is present.

Abstract: Granular detergent composition comprising(1) primary granules of one composition (e.g. spray-dried built detergent) and(2) effervescent granules, of a different composition, containing a binder, an acid, a carbonate reactive with the acid, and an "effect material.

Abstract: Dentifrice containing phosphate ion and flavoring oil and 1,6-di-(p-chlorophenyl biguanidohexane) and water soluble alkaline earth metal salt of a strong acid to stabilize the dentifrice against separation. Calcium and magnesium chlorides are typical stabilizers.

Abstract: A clear gel dentifrice containing "narrow cut" alkali metal lauryl sulphate in which the C.sub.12 content is at least 90% by weight of the total alkyl content and a fluorine providing compound. The dentifrice contains a further anionic surface active agent which is a substantially saturated higher aliphatic acyl amide of a lower aliphatic amino carboxylic acid salt, a substantially saturated higher fatty aliphatic alcohol alkylene oxide sulphate or a mixture of mono- and di- phosphate esters.

Abstract: A new and improved dentifrice including a mixture of polishing agents, the combination providing improved polishing without significant increase in abrasion.

Abstract: A buckle formed of a front face piece and a rear face piece. The face pieces are connected with rivets or screws at adjacent ends and adapted to be braced upon each other when open to an angle up to about 30.degree. apart. At the end of one face piece far from the connecting rivets or screws there is an integral frictional wedged prong perpendicular to the face piece which can engage the other face piece in a positive locking manner.

Abstract: A novel composition to prevent and control dental calculus containing as the essential agent, a magnesium polycarboxylate complex formed by the reaction or interaction of a magnesium compound with a polycarboxylate selected from the group consisting of maleic acid copolymers, sulfoacrylic acid oligomers, and tricarboxy-oxa-butanol or pentanol.
