摘要:
A method for cleaning a surface using a tool with both a cleaning head and a cleaning fluid reservoir housing coupled to an elongated handle, the method comprising the following steps: attaching a cleaning pad to the cleaning head; inserting a replaceable cleaning fluid reservoir into the housing; fluidically coupling the cleaning fluid reservoir to the cleaning head; dispensing controlled amounts of cleaning fluid from the reservoir onto a surface; and distributing the cleaning fluid evenly over the surface with the cleaning pad.

摘要:
An advanced cleaning system having a handle portion with a proximal end and a distal end, a cleaning head portion, the cleaning head portion adapted for use with a removable cleaning pad, and a cleaning fluid reservoir fluidically coupled to the cleaning head portion such that cleaning fluid is controllably allowed to flow via gravity onto the surface to be cleaned adjacent the cleaning head portion.
摘要:
Processes for the production of metal nanoparticles. In one aspect, the invention is to a process comprising the steps of mixing a heated first solution comprising a base and/or a reducing agent (e.g., a non-polyol reducing agent), a polyol, and a polymer of vinyl pyrrolidone with a second solution comprising a metal precursor that is capable of being reduced to a metal by the polyol. In another aspect, the invention is to a process that includes the steps of heating a powder of a polymer of vinyl pyrrolidone; forming a first solution comprising the powder and a polyol; and mixing the first solution with a second solution comprising a metal precursor capable of being reduced to a metal by the polyol.
摘要:
The present invention relates to colored reflective features, e.g., reflective security features or reflective decorative features, that optionally exhibit color shifting and to inks and processes for making such features. The features, as well as the inks optionally used to form the features, comprise nanoparticles and a colorant that preferably modifies a spectrum of light that is reflected by a reflective layer formed from the nanoparticles. The processes involve forming the features from one or more inks using a direct write printing process.

摘要:
This invention is directed to direct write printed reflective features comprising metallic particles and/or metallic nanoparticles. Preferably, the reflective feature are formed by a direct-writing printing process, e.g., a piezo-electric, thermal, drop-on-demand or continuous ink jet printing process, using an ink comprising metallic particles, e.g., metallic nanoparticles. The invention is also directed to inks suitable for printing such reflective features using a direct write printing process and to processes for making such reflective features.
