Title: Multiple master key lock
Inventor: SHEN MINTE
IPC: E05B27/02
Filed: 2003-04-09
Granted: 2004-08-01
Abstract: Inside a hotel, every room on each floor needs to be cleaned every day. It's very inconvenient if the housekeeper needs lots of key to open each room. So there are the designs of master key lock, the master key can be used to open all locks on the same series. Current design uses more latch pins on a series of locks for different locks having same latch pins. Using different combination of latch pins to form a series of locks, the master key fits all latch pins can open all locks in this series. This kind of design needs too much space and has limitation on key combinations. And it costs too much time on design and manufacture comparing with traditional locks. This new invention improves the structure of key locks and has more powerful control function. And the cost of structure and parts are same as that of the traditional key locks. So the new design has more economical benefit than traditional design.

Title: An antibacterial waterborne polyurethane/clay nanoscale dispersion and method of production therefore
Inventor: LEE HSUN-TSING
IPC: C08G71/04
Filed: 2003-10-29
Granted: 2006-05-01
Abstract: A method of producing an antibacterial waterborne polyurethane/clay nanoscale dispersion is presented. A series of quaternary alkylammonium salts or quaternary alkylphenylammonium salts were used to modify hydrophilic clay with microscale particle size and nanoscale inner pore size to be organophilic. The organophilic clay was added during the synthesis process of waterborne polyurethane to form a waterborne polyurethane/clay nanoscale dispersion. The average particle sizes and viscosities of the polyurethane/clay dispersions increase with increasing clay contents under a fixed solid content of the dispersions. The ionic characteristics of clay result in the rising particle size and viscosity of the dispersions. Clay enhances thermal resistance of polyurethane/clay composites without changing their glass transition temperatures. Furthermore, clay introduces antibacterial property to waterborne polyurethane significantly.
