Abstract: The present invention relates to a pen with a paper dispenser. The paper dispenser is composed of a reel tube having a lateral opening and a cavity, a central shaft disposed inside the cavity, a set of spring for shaft with one end inserted and fixed on the central shaft while the other end is connected with the beginning end of the reel for fixing it. The spring set for shaft rotates in accordance with the central shaft and can release the paper through the lateral opening or furl the paper back to the cavity. An annular leafspring set for the paper roll is installed between the reel tube and the spring set for shaft. When the paper is released, the stretching force of the spring set for shaft along radial direction pulls the paper roll out. On the other hand, when the paper roll is curled back to the tube, the compressing force of the spring set for shaft along radial direction provides part of the cavity for receiving the paper.

Title: Nonthermal plasma air treatment system
Inventor: KUENNEN ROY W
IPC: A61L9/014
Filed: 2003-08-07
Abstract: A method and apparatus (10~) for reducing air contamination using a contaminant adsorbent (22~) to remove contaminants from air, and a nonthermal plasma (20~) to desorb and oxidize or detoxify the contaminants. The adsorbent (22~) may be comprised of a unique combination of a zeolite with a material having a high dielectric value. The power supply for the nonthermal plasma reactor (20~) is designed to seek and operate at the system resonant frequency. In one embodiment, the adsorbent material (22~) is separated from the nonthermal plasma reactor(20~). In this embodiment, heat is applied to the adsorbent material to thermally desorb contaminants during a desorption/regeneration phase. Air is recirculated within the system to move desorbed contaminants from the adsorbent material to the nonthermal plasma reactor for decomposition. The recirculating air repeatedly moves contaminants through the reactor until they are destroyed or the desorption/regeneration phase is complete.
