Title: Method of laundering items and purifying waste water therefrom
Inventor: TIBBITTS DAVE
IPC: C11D11/00
Filed: 1996-06-11
Abstract: A method of laundering oily items comprises laundering said items in a wash solution which includes a surfactant system and a source of alkalinity. The source of alkalinity is an alkali metal aluminate preferably sodium aluminate at a concentration effective to have at least about 25 ppm of the alkali aluminate present in the wash solution measured as alumina. The wash solution is then separated from the laundered items and its pH reduced to about 9 or less. A destabilizing polymer such as diallyldimethyl ammonium chloride can be added. This combination causes the oil and grease to separate from the wash solution and float to the surface along with the sodium aluminate. If the concentration of the sodium aluminate is above about 100 ppm preferably about 250 ppm, there is no need to add the destabilizing polymer. This does not affect the overall efficiency of the detergent, yet significantly improves the ability to separate the oil and grease from the waste wash solution.

Title: Computer software development time management and task completion and prediction apparatus
Inventor: EMRICH MARCO A
IPC: G06Q10/10
Filed: 1998-03-30
Abstract: A computer software application en the form of a time management and task completion and prediction apparatus by which project completion can be ascertained and management of a project can be maintained with a high  efficiency and accuracy. The software application is a web-based application which enables users to proactively manage and accurately predict strategic software development and deliverables. This application and delivery management system comprises distributed data collectors, an application server and a browser interface. The data collectors automatically gather data already being generated by various tools within the organization. This data is constantly being collected and fed into the application server, thereby providing objective and updated information. New tools can be easily added without disrupting operations.  The data collected is fed into the application server which is the brain of the apparatus. The application server analyzes the data collected by the data collectors to generate a statistically significant probability curve. This curve is then compared to the original planned schedule of product delivery to determine if the project is meeting its targets.  Based upon this comparison, the software application  predicts a probable delivery date based upon the various inputs and variables from the development process. In addition, the application server also generate early warning alerts, as needed and indicated. At such time as the software apparatus identifies a potential problem, the alerts automatically inform the user, so as to mitigate a crisis and assist with resolution of the problem. The alerts are communicated to the designated user by e-mail. The final component of the application server is the software quality management capability, which ensures that all of the manual and automated testing activities are coordinated and archived.

Abstract: A camouflage surface for concealment from, and deception of, a herbivorous animal comprises a camouflage pattern made up of at least two different sets of areas which reflect electromagnetic radiation at wavelengths in the near-infrared range of the electromagnetic spectrum. All the areas of each set reflect said near-infrared radiation in the same fashion as one another and in a fashion different from the fashion in which the areas of each other set reflect said radiation. The different sets of areas all have, in the near-infrared range, spectral reflectance curves having reflectance maxima at wavelengths of above 680 nm.  Each spectral reflectance curve which the surface has in the visible light range of the electromagnetic spectrum is without a reflectance maximum in the wavelength range of 480 - 680 nm and each spectral reflectance curve which the surface has in the visible light range has a reflectance maximum at a wavelength below 480 nm.
