US Patent:

6487728, Dec 3, 2002

Filed:

Sep 17, 2001

Appl. No.:

09/954539

Inventors:

Ronald Nelson Cook - Red Bank NJ 07701

International Classification:

A41B 902

US Classification:

2403, 602 67

Abstract:

This male penis sheath underwear/bandage is worn in place of the traditional male underwear brief or boxer short. The form of the tubular sheath follows that of the penis. The tubular sheath is open at each end and is provided with a slit at the proximal end through which the scrotum is passed. The garment is unique in that it is self-securing, requiring no waistbands or leg straps. Also, the sheath does not have to be removed in order to urinate.

Abstract:

A method has been developed for the solution-based metal exchange of carboxylato-alumoxanes [Al(O). sub. x (OH). sub. y (O. sub. 2 CR). sub. z ]. sub. n with a wide range of metal cations. Metal-exchanged carboxylato-alumoxanes are new, particularly those in which about 10% to about 50% or more of the Al ions are exchanged for other metal ions. Additionally, the carboxylic acid ligands can be stripped from the boehmite core of metal-exchanged carboxylato-alumoxanes at low temperature leading to the formation of metal-exchanged boebmite particles. These new material phases can be used as intermediates for preparation of mixed metal aluminum oxide materials. Thermolysis of the metal-exchanged carboxylato-alumoxanes or metal-exchanged boehmite particles results in doped aluminas (M/Al. sub. 2 O. sub. 3), binary (MAlO. sub. x), ternary (MM'AlO. sub.
