Abstract: ABSTRACT OF THE DISCLOSURE             Lifesaving apparatus in the form of a jacket having appended sleeves and a collar includes pliable inner and outer shells that are joined along construction seams which define several closed, isolated pockets.  Each pocket contains at least one laminar slab of thermally insulative, closed-cellular foam flotation material that is positioned to define a vacant margin alongside each seam.  This seam construction results in a flotation garment that is less restrictive and more comfortable and which permits a high degree of user mobility either in or out of the water.  Flota-tion material in the collar, together with its compliant seam, causes the collar to rise automatically to support at least partly the head of a subject when immersed in water.  Vents in the back of the jacket provide normal ventilation and also exhaust any air that may be trapped in the jacket to avoid turning an unconscious swimmer face down in the water-whereas unequal buoyancy in the chest and back portions produce a turning moment to rotate the swimmer face upwards and on his back.  And, exposure to low water temperatures is reduced by a protective hood and by openable closures at the wrists, neck and waist that minimize water flow through the jacket.

Abstract: ABSTRACT EASY-OPEN WRAPPER FOR CYLINDRICAL PRODUCTS A wrapped cylindrical body such as a catamenial tampon is provided with a wrapper which will maintain the body clean and dust and moisture proof and can easily be opened. Specifically, the cylindrical body is wrapped in a wrapper having perforations arranged in a pattern whereby almost the entire wrapper can be removed in one motion without the need for pulling substantial quantities of wrapping from the ends of the cylindri-cal body.  Further, the wrapper provides no open path for dust and other contaminants to reach the wrapped product.  These advantages are achieved by providing two perforated zones in the wrapping material, double wrapping the cylindrical body and having the perforations of each of the zones offset so as to close any path into the product.  The zones are located so as to overlie each other when the product is wrapped and are adhered together whereby essentially the entire product may be unwrapped in a single unwrapping operation.

Abstract: ABSTRACT OF THE DISCLOSURE            A steam heated dryer drum having one or more spoiler bars secured against its inner shell wall to extend longitudinally and substantially parallel with the axis of rotation.  The spoiler bars generate turbulence in the condensate to lower the resistance to heat transfer through the shell wall.  No screws, bolts, rivets or the like, which would necessitate penetration of the shell wall, are required or used to secure the bars.  In one embodiment, the bars themselves have a bridge-shaped cross sectional configuration and are made of a magnetic material.  Their bridge legs form the north and south poles of the magnetic bar and have their ends contoured to correspond to the drum shell radius of curvature.          In another embodiment, magnets having a bridge-shaped cross section are used.  These magnets'are of a relatively short, finite length which is considerably less than either the spoiler bar or the drum shell lengths and have their inner bridge opening contoured to fit over and hold the spoiler bar which is non-magnetic and extends longitudinally along the roll shell wall for as far as desired.  The magnets are then spaced along the bar so that less magnetic material can be used.
