Inventor: CHAWLA MANMOHAN S
IPC: F42B1/024
Filed: 1996-07-26
Granted: 1999-10-19
Abstract: An improved shaped charge for generating a jet. A lens shaped waveshaper is positioned within the explosive material of a shaped charge to modify the shape of the divergent detonation wave into a planar wave or a converging wave. The waveshaper is formed with a low sound speed material having a high index of refraction. By reshaping the detonation wave, the acceleration of the shaped charge liner is increased, and the penetration depth and hole size of the jet can be increased. The shaped charge operates more efficiently, thereby requiring less explosive material than a conventional shaped charge.

Abstract: A method for manufacturing tape tab stock that may be used to produce tape tabs (40) for use with disposable absorbent articles, as well as a method for manufacturing tape tab stock that can be produced on-line and concurrently with the disposable absorbent article to which the tape tabs (40) are joined. The first step in the process is to provide a backing substrate (52) upon which the adhesives of the tape tab can be applied. Once the backing is provided, a pressure sensitive adhesive (54) is applied to regions of one side of the backing substrate. The backing substrate (52) is then slit in a direction parallel to the machine direction and the release surface of a release substrate is placed in contact with the pressure sensitive adhesive (54), forming a laminate comprising the backing substrate (52) and the release substrate. The release substrate preferably covers the entire surface of the backing substrate (52) upon which pressure sensitive adhesive (54) has been applied. The surface of the laminate, including the surface of the release substrate that is not in contact with the pressure sensitive adhesive (54), and any of the backing substrate (52) not covered by the release substrate is then coated with a second adhesive for joining the tape tabs to the absorbent article. After the second adhesive is applied to the surface of the laminate, the laminate is slit in a direction parallel to the machine direction and either rewound for shipping or storage, or fed to a taper unit that is integrated into the absorbent article manufacturing line. The taper unit cuts individual tape tabs (40) and applies them to the absorbent article chassis.

Abstract: An aglucone isoflavone enriched vegetable protein extract and protein material are provided, as well as a high genistein content material and a high daidzein content material. Isoflavone conjugates in a vegetable material are converted to isoflavone glucosides by treating the vegetable material at a temperature and a pH for a period of time sufficient to effect the conversion. The isoflavone glycosides are converted to glucose isoflavones by enzymatic reaction. The vegetable material is extracted with an aqueous extractant having a pH above about the isoelectric point of protein in the vegetable material to extract protein and the isoflavones either before or after conversion of the isoflavone conjugates to isoflavone glucosides or the conversion of the isoflavone glucosides to aglucone isoflavones. An aglucone isoflavone enriched protein material is produced by precipitating the protein and aglucone isoflavones from the extract. A high genistein content material or a high daidzein content material may be produced from the aglucone isoflavone enriched protein extract or aglucone isoflavone enriched protein material by separating the high genistein or high daidzein content material from the extract or protein material.
