Patent MX-PA04011909-A (MX)
Title: Hyperbranched polymers.
Inventor: ERIK MIKAEL STOLT
IPC: A23G4/00
Filed: 2003-05-30
Abstract: The present invention is directed to a process for preparing a hyperbranched polymer having a weight-average molar mass of at least 30,000, comprising coupling a first prepolymer having at least three functional end groups with a second prepolymer having at least two functional end groups by a dehydration condensation reaction between the end groups in the prepolymers. According to the present invention the number of arms and/or molar mass of the functionalized prepolymers can accurately be adjusted, thus affecting the properties of the resulting hyperbranched polymer in a desired way. Thus the polymer can be equipped e. g. with hydrophobic and hydrophilic parts. Also, the number of functional end groups, that optionally can be used for further chemical reactions, in the hyperbranched polymer can easily be adjusted to a desired level. The hyperbranched high molar mass polymer can be prepared in high yields without the use of organic solvents or linking compounds, which is advantageous from an environmental as well as an economical point of view.

Title: Uv led based water purification module for intermittantly operable flow-through hydration systems.
Inventor: MILES MAIDEN
IPC: A45F3/20
Filed: 2003-09-24
Abstract: A wearable or portable intermittently operable hydration system (10) includes a purification module (22) that contains one or more solid state UV devices that are positioned in the path of hydrating fluid, or water, flow through the hydration system to a mouthpiece (18) or other orifice. The purification module (22) provides a path for the fluid past one or more solid state UV devices, such as UV LEDs, that produce UV radiation in a germicidal range. When the fluid is flowing past the UV LEDs, the LEDs are turned on to provide sufficient UV radiation to purify the water. The UV LEDs are instant on devices with essentially no ramp-up required, and a sensor (20) or other signaling means in the flow path controls the turning on of the UV LEDs whenever the user initiates the fluid flow. The fluid flow path may run from a bladder (12) in a backpack (19) worn by the user, a sports bottle worn by or carried by the user or may be through a water filtration system that a user operates via a pump. The power for the purification module may come from batteries, solar cells, fuel cells, power converted from pumping or winding action or any combination thereof. Further, UV LEDs may be included in the walls of the container as additional or alternative sources of UV radiation. The UV LEDs in the walls of the container may then be turned on when sufficient energy is available, as a precaution against, for example, a change in environmental conditions.
