摘要:
An aqueous machining fluid composition having improved resistance to microorganisms is provided. The fluid composition comprises in admixture: a) water, b) a water insoluble organic lubricant, c) a surface active agent selected from the group consisting of nonionic, anionic having up to and including 12 carbon atoms, and cationic surfactants and mixtures thereof and d) a water soluble polyquaternary cationic biocide. Machining processes comprising the step of supplying said aqueous machining fluid to the interface between the tool and the workpiece are also provided.
摘要:
A method is provided for obtaining an acceptable configuration of a thermally processed plastic container packed with food. Improvement in container configuration is attained by proper container design and by maintaining proper headspace of gases in the container during thermal processing and/or by controlled reforming of the bottom wall of the container. Further improvements are attained by controlling the thermal history of the empty container, such as by pre-shrinking the container before it is filled with food and sealed.
摘要:
Corrosion inhibiting aqueous functional fluids having high stability are provided which contain (a) water, (b) a corrision inhibiting, surface active, water soluble or dispersible alkali metal, ammonium or organic amine salt of a water insoluble carboxylic acid group terminated monoamide, (e.g. the triethanolamine salt of the carboxylic acid terminated monoamide reaction product between maleic acid and 1-amino-2-ethyl hexane), (c) a second surface active agent and optionally, (d) water soluble or dispersible lubricant. These functional fluids are useful as a metal working fluid or hydraulic fluid.
摘要:
A method of coating a stent is presented such that less than 50% of the total amount of 40-O-(2-hydroxyl)ethyl-rapamycin, or an analog or derivative thereof, is released in vivo in a 24 hour period, wherein the method comprises exposing the coating to sufficient temperature to modify the structure of the polymer.

The present invention provides waterproof, breathable non-textile seamed articles which exhibit high levels of durability and allow wearers a high level of flexibility and article strength. This invention is of particular interest for use in dexterous hand coverings and conformable foot coverings.
摘要:
A method and system and the use of a 3-D positioning system for monitoring a landfill and landfill material added thereto and undergoing compaction and measures in real time the relative density of the compressed landfill material. The method and system calculates thickness, volume, density during the landfill operation to ensure that the landfill is comprised of compacted layers of substantially optimized density.
摘要:
Magnetic means and apparatus for implementing rail bonds and rail feeds. A rail bond embodiment comprises an electrical conductor. Mechanically and electrically coupled to each end of the electrical conductor is a magnet that comprises a magnetic material that is plated with an electrically conductive material. In an alternative embodiment, the magnet comprises a magnetic material that is disposed between two pieces of steel or other metal. In operation, the two magnets are attached to two rail sections, across a joint separating the rails, via the attractive magnetic force between each magnet and its associated rail. In this way, the electrical circuit comprising the rails is maintained.
摘要:
A method is provided for obtaining an acceptable configuration of a thermally processed container packed with food. Improvement in container configuration is attained by proper container design, by maintaining proper headspace of gases in the container during thermal processing, proper pressure outside the container during the cooking cycle and cooling cycle of the process and/or by controlled reforming of the bottom wall of the container. Further improvements are attained by controlling the thermal history of the empty container, such as by pre-shrinking the container before it is filled with food and sealed.
摘要:
A method and system for in vivo dermal absorption testing of a laboratory animal uses a mask and harness for protecting the respiratory tract of the animal when the animal housed within a sealed chamber with a hazardous test vapor introduced in the chamber. Because of the difficulty of getting a good seal with a protective mask on a laboratory animal, this system is designed with an air leak from inside the mask into the chamber. To ensure that the test vapor does not infiltrate the mask nor leak from the chamber, the vapor is maintained at a negative pressure within the chamber as compared to the external atmospheric pressure and air is supplied to the mask for the animal to breathe at a positive pressure and at a greater rate than that needed by the animal.
摘要:
Corrosion inhibiting aqueous functional fluid compositions are provided which comprise (a) water (b) a water soluble or dispersible, surface active, corrosion inhibiting alkali metal, ammonium or organic amine salt of a water insoluble C.sub.4 to C.sub.9 aliphatic monohydric secondary alcohol half ester of a hydrocarbon cyclic dicarboxylic acid or anhydride, said half ester having a molecular weight of from 240 to 297, (e.g. monoethanolamine salt of the 2-octanol half ester of phthalic acid) and optionally (c) a substance selected from the group consisting of an anionic surfactant, a nonionic surfactant, a cationic surfactant, an amphoteric surfactant and a lubricant or mixture thereof, the fluid having a pH in the range of 8 to 12. Such aqueous fluids are useful as metal working fluids.
