Visually clear dentifrice comprising a water-insoluble aluminosilicate sodium salt complex in which silica is interbonded with alumina, which alumina is present in amount up to 3.3% by weight of the polishing agent in which the mole ratio of silica to alumina is at least about 45:1, said polishing agent having a refractive index of about 1.44-1.47 and a gel vehicle for said polishing agent having about the same refractive index as said polishing agent, said polishing agent being substantially in...

Visually clear dentifrice comprising a water-insoluble aluminosilicate sodium salt complex in which the proportion of alumina is up to 3.3% by weight and in which the mole ratio of silica to alumina is at least about 45:1, as a polishing agent having a refractive index of about 1.44-1.47 and a gel vehicle for said polishing agent having about the same refractive index as said polishing agent, said polishing agent being substantially invisible in said gel vehicle.

A clear candle made from a gel comprising mineral oil containing blends of diblock and triblock copolymers based on synthetic thermal plastic rubbers. The clear candle is stable, does not separate, and does not flash when burned. The candle, although free standing at room temperature, will preferably be supplied in a container, and it may be colored and/or scented.

A radiometer for use in aircraft as part of a clear air turbulence detector apparatus, constructed to provide signals representing the atmospheric temperatures of at least three regions ahead of the aircraft and centered about sight-lines having different angles of elevation or declination with respect to the aircraft, is connected to means for deriving a temperature-difference signal indicating the difference between the measured temperature of a central one of the regions and an average of the...

This disclosure describes an apparatus for warning the pilot of an aircraft of a region of clear air turbulence. A multi-channel radiometric sensor mounted on the aircraft detects both the ambient temperature of the air and any temperature anomaly that is present along the forward flight path. In those cases where temperature anomalies are associated with the presence of a clear air turbulence region, the invention provides means for remotely sensing these temperature anomalies through the appli...

A clear viewing screen for vehicles, particularly for vehicles which have to operate under polar conditions, comprising a fixed screen element, a rotatable disc like screen element mounted in front of the said fixed screen element with the interposition of a labyrinth joint at the periphery of the said rotatable screen element, a motor for driving the said rotatable screen element, a motor for driving the said rotatable screen element, and electric heating elements in the chamber between the fix...

The degree and reproducibility of cohesive bonding between gum-type organosiloxane elastomers cured by a platinum-catalyzed hydrosilation reaction and organic polymer substrates are increased when the composition used to prepare the elastomer contains an amount of silanol-functional polydirganosiloxane sufficient to impart an activity number of at least 40 to the polydiorganousiloxane gums present in said composition.

A medical device for performing a therapeutic procedure on a patient. The medical device includes an elongate probe extending to an applicator end and a visually transparent tip positioned adjacent the applicator end. The device also includes an electrode positioned on the tip so that the electrode may be viewed through the tip. The electrode is communicative with an energy source for delivering energy to the electrode when performing the therapeutic procedure on the patient. The probe and tip a...

Vending machine product is moved by an "X-Y mechanism" having two stationary electronically controlled drive "motors," which drive tension elements that position horizontally and vertically sliding components. A separation and selection system uses a "rotator" to release a product from a tray and a "gate" to separate the products into two columns on the tray. A "lever" mechanically links these components. Products move off the tray by a spring powered "slider" on the tray. There is only one "rot...

A printing device including a plurality of cartridges, at least one cartridge including a visible ink and at least one cartridge including a clear ink; a print portion; and an accessory module in connection with the print portion; wherein the clear ink of at least one cartridge has a longer drying time than the visible ink of at least one cartridge.
