Abstract: A patient rotation device including an armature and a patient engagement assembly. The armature is structurally configured for attachment to an outside structure. The armature has a first end and a second end spaced apart from the first end. The patient engagement assembly includes a housing and a rotational assembly. The housing is attachable proximate the second end of the armature. The rotational assembly includes an axle and a rotational member. The rotational member is rotationally coupled to one of the housing and the armature, and structurally configured to be being positionable over a surface of a bed. Methods are also disclosed.

Abstract: This invention provides a novel solution for a nursing pad that is configured to provide direct access to an absorbent insert, resists slippage while worn inside a bra or a shirt, and effectively wick leaking breast fluid via an undergarment pad assembly comprising a receptacle with a pocket, at least one absorbent insert wherein the at least one absorbent insert is retained and semi-enveloped within the pocket of the receptacle, and may include at least one non-slip surface on a backside of the receptacle.

Abstract: Disclosed is a polymetallic supported catalyst component comprising an activated anhydrous MgCl2 solid support which has been treated with at least one treatment of at least two halogen-containing transition metal compounds, wherein one is a halogen-containing titanium metal compound and one is a halogen-containing non-titanium transition metal compound, optionally, in the presence of an electron donor and the processes for producing the component. A catalyst for the polymerization of at least one alpha-olefin of the formula CH2═CHR, where R is H or a C1-12 branched or straight chain alkyl or substituted or unsubstituted cycloalkyl, by reacting this supported catalyst component with an organometallic cocatalyst, optionally in the presence of an electron donor, and the polymerization of at least one alpha-olefin with the catalyst are also disclosed.

Abstract: Disclosed is a polymetallic supported catalyst component comprising an activated anhydrous MgCl.sub.2 solid support which has been treated with at least one treatment of at least two halogen-containing transition metal compounds, wherein one is a halogen-containing titanium metal compound and one is a halogen-containing non-titanium transition metal compound, optionally, in the presence of an electron donor and the processes for producing the component. A catalyst for the polymerization of at least one alpha-olefin of the formula CH.sub.2 =CHR, where R is H or a C.sub.1-12 branched or straight chain alkyl or substituted or unsubstituted cycloalkyl, by reacting this supported catalyst component with an organometallic cocatalyst, optionally in the presence of an electron donor, and the polymerization of at least one alpha-olefin with the catalyst are also disclosed.

Abstract: Disclosed are catalysts for the polymerization of alpha-olefins comprising the reaction product of:(A) an Al-alkyl compound;(B) a trifluoropropyl substituted silane compound;(C) a solid component comprising a titanium compound having at least a Ti-halogen bond and an electron donor compound both supported on an activated anhydrous magnesium dihalide, and the process of using said catalysts.
