摘要:
Polymeric anti-microbial agents produced by substituting the nitrogen atoms in the backbone of ethylenimine polymers, for example, substitution with aralkyl groups, are provided. The agents are believed to have low human toxicity while being effective against a variety of pathogens and are useful in applications involving human contact, such as cosmetics, hair care products and textiles, as well as in applications with much less human contact, such as coatings.

Perfluoroalkyl-allyloxy- and perfluoroalkyl-iodopropyloxy-substituted polyaminoacids or poly-R.sub.F -fluoroallyl-substituted polyaminoacids which contain, in random distribution, q units of A-1, r units of A-2, s units of A-3 and t units of A-4 in which A-1 and A-2 are perfluoroalkyl-substituted amino groups of the formulae ##STR1## A-3 is a hydrophilically substituted amino or amido group of the formula ##STR2## and A-4 is a substituted amino or amido group of the formula ##STR3## where the variables are as defined herein, are useful to provide oil repellency to paper and as foam stabilizers in alcohol resistant--aqueous fire-fighting foam fire-fighting foam compositions.
摘要:
Perfluoroalkyl-substituted amines, acids, amino acids and thioether acid compounds containing a perfluoroalkyl-iodoalkyl or perfluoroalkyl-alkene group as well as derivatives thereof, are described. They are useful as surfactants in a variety of applications where low surface tensions are required, including coating formulations for glass, wood, metal, cement, paper, textiles, as foam control agents in polyurethane foams and especially in aqueous fire-fighting formulations.

A grace period is provided during which the features of a software application may be fully utilized and appreciated without requiring entry of a product identification key code or other authorization code. After loading a software application onto a user's computer, a grace period is provided during which the software application may be booted and used with all its associated features and functionalities before requiring entry of a product identification key code or other authorization code. At the end of the grace period, entry of the appropriate product identification key code or other authorization code is required, followed by activation of the software application.
摘要:
An integrated application setup enables the implementation of application customizations through patch technology. A customization patch extends a typical patch file format such that the customization patch serves as a container for application customization data useful for customizing an application using different underlying technologies. The contents of the customization patch can include transforms, cabinet files, and XML content containing customization information.

Method and apparatus for a system monitor (20) embedded in a programmable logic device (10, 50, 60) are described. The system monitor (20) includes a dynamic reconfiguration port interface (205) for configuring or reconfiguring the system monitor (20) during operation thereof. The system monitor (20) includes an analog-to-digital converter (200) which is reconfigurable responsive to input via a dynamic reconfiguration port (201).
摘要:
A hinge assembly (2100) includes a hinge body (2102) made of two hinge body halves (900). Each hinge body half is identical so that only one part need be manufactured, and two of them used to form the hinge body. Each hinge body half has a first leg (902) that is longer than a second leg (904). The first leg has a retaining lip (912) at the end which forms a retaining feature. Each leg of the hinge body defines an axis of rotation for the body elements (104, 106). A portion (1508) of a flexible circuit board (1506) is captured between the hinge body halves so as to electrically interconnect circuitry placed in each body element. A detent mechanism is provided to hold the body element in preselected positions with respect to each other, and includes a spring (2106), a cam (2108) and a cap (2110) having cam follower features (2118). The cam is held in place with respect to the body element housing, while the cap is fixed in position with respect to the hinge body. To stabilize the rotation of the body elements, a hook (2404) retains a collar edge (2402) upon rotation of the respective body element.
