Abstract: A metal oxide-coated mica pearlescent pigment having a coating of copper chromite thereon is provided.

Abstract: In one embodiment, the present invention relates to a KOH neutralized metatitanic acid mixture containing from about 30% to about 99% by weight metatitanic acid, from about 1% to about 20% by weight of a titanyl compound, and optionally from about 0% to about 55% by weight titanium dioxide, wherein the KOH neutralized metatitanic acid mixture has a pH from about 4 to about 6.5. In another embodiment, the present invention relates to a pigment composition made by combining a KOH neutralized metatitanic acid mixture and at least one guest element precursor, wherein the KOH neutralized metatitanic acid mixture contains metatitanic acid, a titanyl compound, and optionally titanium dioxide, the KOH neutralized metatitanic acid mixture having a pH from about 4 to about 6.5.

Abstract: A floating siphon-type regulator for incorporation in parenteral fluid administration sets and which is characterized by a design enabling a simplified, fast start-up procedure and which incorporates a simple, effective means for increasing or decreasing flow rates as called for by the viscosity of the particular solution being administered.

Abstract: A turbofan-ramjet engine is provided with optional duct burning in the turbofan mode. A core engine is provided with a first annular passage therearound for directing airflow around the inlet of the core engine. A second annular passage having a fan directs air flow into the inlet of the core engine and said first annular passage. A third annular passage extends around the first and second annular passage with the first and third annular passage each directing their flow into a common annular combustion chamber. Variable vanes are provided in the first and third annular passages to provide for blocking off the passage or acting as swirl vanes depending on mode of operation. Blocking vanes are also provided in the annular exhaust passage of the core engine. Coannular nozzles are provided with one located at the exhaust of the core engine and an outer one located aft of the common annular combustion chamber.

Abstract: A sphygmomanometer pressure release means, i.e. a means for releasing the pressure in the pneumatic cuff thereof by simple bending pressure applied to the tubing extending from the "squeeze" bulb to the pneumatic cuff and at a point along the tubing adjacent the squeeze bulb.

Abstract: A parenteral fluid administration set characterized by a floating siphon operating within a deformable-reformable, plastic-walled, generally cylindrical flow regulator having a normally open-ended overflow tube extending uprightly therein from its bottom end-wall, being thus generally similar both structurally and to a degree functionally to the fluid administration set disclosed in my copending application Ser. No. 608,576 filed Aug. 28, 1975, (now U.S. Pat. No. 3,949,745 dated Apr. 13, 1976) but featuring means whereby the siphon may be primed to initiate fluid flow in controlled amount through the longer leg of the siphon more simply end effectively than by the siphon priming means according to my aforesaid prior-filed application.

Abstract: A parenteral fluid administration set comprising a container having therein a supply of a fluid to be administered intravenously and being characterized by a floating siphon operative to flow fluid from said container supply thereof at a predetermined rate of flow, said floating siphon comprising a float and at least one siphon U-tube whose shorter leg extends through and is affixed to the float and whose longer leg terminates below the inlet end of said shorter leg and a substantial distance above the container bottom, said longer leg opening to and flowing fluid into an axially non-rigid fluid-flow tube extending through the body of the fluid in said container and delivering same through the container bottom to an I.V.

Abstract: A parenteral fluid administration set comprising a plastic bag adapted to be supplied with a predetermined quantity of the parenteral fluid, said bag being foldable over on itself about a transverse fold-over line, a floating siphon enclosed within the plastic bag adapted to follow the level of the parenteral fluid supplied thereto, said floating siphon being adapted to be forced relatively downwardly to substantially its lowermost position in the plastic bag responsive to folding over of the upper portion of said bag on its lower end portion about said fold-over line, thereby immersing the float of the floating siphon in fluid contained in its lower end, as effects conditioning of the floating siphon for operation, the outlet leg of the siphon terminating in a fluid outlet end, said floating siphon being rendered operative to dispense fluid from the plastic bag through said siphon outlet end upon the plastic bag being unfolded and suspended from its upper end.

Abstract: A device for administering parenteral fluids intravenously at a uniform rate achieved by a floating siphon-type flow regulating means.
