Abstract: This invention relates to a polypropylene bumper cover composition, particularly to a polypropylene bumper cover composition with improved contraction rate, painting properties, and molding properties. This composition includes 55 to 70 wt % of a polypropylene resin, 28 to 45 wt % of an ethylene-propylene rubber component, 2 to 5 wt % of an inorganic filler, 1 to 2.5 wt % of high density polyethylene, and 2.5 to 7 wt % of oxidation inhibitor, lubricant and carbon black. The ethylene-propylene rubber component may include two ethylene-propylene rubbers having different Mooney viscosities. The inorganic filler can be talc or fine talc.

Abstract: New topically applied treatments for structurally deteriorated or otherwise aged skin are shown by comparative data to effect structural improvements in the deteriorated skin, as shown by skin-thickening data. The disclosed treatments disrupt the skin's water barrier and elevate trans-epidermal moisture loss (TEML) for extended periods of weeks or months and include methods of mechanical or solvent action, for example, tape stripping, or acetone washes. Preferred treatments use cosmetic creams or gels with active ingredients such as lactic acid as a primary, water-soluble barrier disruption agent, a retinoid, for example vitamin A palmitate as a lipid-soluble barrier disruption agent and a particular cerebroside to inhibit barrier repair. Such novel creams or gels can be applied daily for extended periods to provide chronic, sustained disruption of the barrier as indicated by significantly elevated TEML.

Abstract: A process is described for the purification of plasminogen activator (PA), wherein a solution containing such as plasminogen activator is brought into contact with a carrier-bound polysulfate of a saccharide or sulfated sugar, the liquid is removed, and the PA bound by this material is eluted.

Abstract: A device for positioning a photographing lens to focus the lens on an object is disclosed. The device comprises distance detecting means for detecting a distance to an object to provide an output signal, the distance detector detecting the distance when the object is positioned in the range of ordinary photographing distances and in the range of distances shorter than the ordinary photographing distances, a position determining system for determining the position of the photographing lens in the direction of the optical axis according to the output signal, and a drive system for responding to an output of the position determining system. The drive system includes a cam which is displaced to move the photographing lens along the optical axis.
