Abstract: A bioremedition device and process for remediation of waste collection systems. The present invention preferably comprises an bioactive element having an outer and an inner portion. The concentration of the bioactive element in the outer portion differs from that of the inner portion so that the concentration is greatest when the waste material is first exposed to the outside of the element and diminishes while the solid dissolves in the waste material. The outer portion is disposed about the inner portion such that substantially all of the outer portion is dissolved for delivery of the bioactive element into the waste material before dissolution of the inner portion occurs. The outer portion has a relatively great bioactive effect for remediating the waste material and the inner portion has relatively lesser bioremediating effect for maintaining the waste material in the collection systems.

Title: Readily defibered pulp products and method of their manufacture
Inventor: WEST HUGH
IPC: D21H21/10
Filed: 1997-10-06
Abstract: The invention relates to cellulose fluff pulp products that are debondable into fluff with markedly lower energy input, to a process for making the products, and to absorbent products using the fluff. Most of the pulp products show no reduction in liquid absorbency rate from that of untreated fiber and significantly higher rates than pulps treated with the usual debonding agents. The products are made by adhering fine noncellulosic particles to the fiber surfaces using a retention aid. The fiber is preferably treated with the retention aid in an aqueous suspension for a sufficient time so that the retention aid is substantively bonded with little or none left free in the water. The fine particulate additive is then added and becomes attached and uniformly distributed over the fiber surfaces with very little particle agglomeration occurring. The fiber is most usually not refined or only very lightly refined before sheeting. However, it may be significantly refined to produce a product having a very high surface area. Kaolin clay is a preferred particulate additive. The treated pulp may be mixed with other fibers before sheeting or after it is debonded into a fluff. The fluff is highly advantageous in the absorbent portions of personal care products such as diapers or sanitary napkins.

Title: Software program protection mechanism
Inventor: THOMSON SCOTT ALAN
IPC: G06F21/00
Filed: 1999-12-10
Abstract: An improved software protection mechanism is disclosed whereby both the "asset files" of a software program and the core executable program itself are transformed in such a way that any redistribution of the modified executable program would also require redistribution of the corresponding transformed asset files. In operation, a file transformation module is used to intercept any file activity from the operating system.      The file transformation module will perform the required reverse transformation only if the invoking request to the operating system is identified as being for transformed data bound to or from the modified executable program. A protection module containing asset lists, calling process identification information, transformation keys, and optionally other information such as transformation algorithms is used in association with the file transformation module.
