20050279655, Dec 22, 2005

Filed:

Jun 16, 2004

Appl. No.:

10/869222

Inventors:

Sabrina Chen - Sugar Land TX, US

International Classification:

B65D085/30
B65D085/57

US Classification:

206307100, 206307000

Abstract:

A holder for a cellular phone chip includes a card body having a first side and a second side and includes a sheet having edges attached to the first side of the card body. The sheet forms an open pouch on the card body. The cellular phone chip is insertable into and removable from the open pouch. The chip is substantially held within the pouch by an interference fit with the sheet and the first side of the card body. The card body can be approximately the same size as the chip or can be approximately the same size as a credit card. Multiple sheets forming multiple pouches can be attached to the card body. On side of the card body can have a fastener attached to the second side of the card body for attaching the card body to another item intended to carry the holder and cellular phone chip.

Abstract:

A thermal conversion pyrolysis reactor system (10) is provided for use in providing a continuous flow type pyrolysis reaction for conversion of carbonizable input materials ("MW") (12). The reactor system (10) utilizes a diffusion material ("MD") (14) which is preheated and admixed with the MD (12) in order to facilitate pyrolysis and to partially catalyze reactions. Subsystems are provided to receive gaseous (30), liquid (32) and solid (32) phase outputs. The reactor system (10) includes further component subsystems for waste material MW input (22), MD input (26), reactor chamber (24), and heating (28). The MD (14) is preheated by being carried through the reactor chamber (64) prior to admixing with the MW (12) and further by exhaust gases (94) from the furnace space (88) being directed through a heat exchanger (126). The system (10) provides for recycling of MD (14) and is substantially self powered as a result of using combustible hydrocarbon gases produced by the pyrolysis reaction as fuel for turbulent burners (72). Input materials are evacuated of oxygen and a positive internal pressure is maintained in the reactor chamber (66) in order to maximally facilitate oxygen free pyrolysis.

Appl. No.:

Inventors:

Sabrina Pichee Chen - Sugarland TX, US

International Classification:

B31C 11/00

US Classification:

493293

Abstract:

A plastic or other film bag is formed from a continuous extruded tube. The tube is flattened and sealed across its width at intervals to form bag bottoms. The bags are joined to one another at a perforation line and folded in thirds lengthwise prior to being rolled into a compact roll, either with or without supporting core. After folding the bags may be chisel cut through the center of the perforation line to assist in dispensing of the bags. The chisel cut will extend through all layers of the bag when folded, resulting in three chisel cuts in the bag. The bags may be gusseted for part or as much as all of their width. The bags may also be corona treated and printed on their outer surfaces. The bags may be formed from partially recycled materials and various combinations of linear low density, medium and high density polyethylene.
