Title: Opposed current power converter
Inventor: STANLEY GERALD R
IPC: H02M3/158
Filed: 1997-03-03
Granted: 2000-06-11
Abstract: A power converter includes a pair of switches, each of the switches being connected between positive and negative constant DC voltage sources and a common output node which is connected to a load.  A modulator opens and closes the switches in a sequence in which the electrical current controlled by the switches are in opposition to one another at the common output node, and are summed at the output node.  The modulator includes a triangle wave generator and comparators which are connected to an error amplifier to provide a bearing switching voltage to the comparators.  The comparators switch the control switches in response to the triangle wave generated by the triangle wave generator increasing above and decreasing below the reference levels.  Underlap and overlap of the converter is controlled by varying of the DC bias level of the triangle wave.

Title: Improved rigid polymeric beverage bottles with improved resistance to permeant elution
Inventor: WOOD WILLARD E
IPC: C08L101/00
Filed: 1997-03-20
Granted: 2002-06-11
Abstract: Carbonated beverages can have a substantially reduced concentration of water soluble materials derived from biaxially oriented thermoformed beverage containers. Such containers can comprise a permeant barrier and an active trap for water soluble materials that can be removed from the thermoplastic by extraction into the carbonated beverage. The improved container material comprises a blow molded thermoplastic polyester web comprising a compatible modified cyclodextrin material having pendent moieties or substituents that render the cyclodextrin material compatible with the container thermoplastic. The cyclodextrin material, after it is added to the polymer material, acts as a barrier and to trap extractable materials as they permeate through the thermoplastic polyester. The cyclodextrin molecule has a large center cavity having properties that increase the likelihood that organic molecules will be absorbed and trapped in the center pore. The resulting polyester is substantially resistant to any extraction of soluble materials from the polyester material by the carbonated beverage.

Title: Method of applying light reflection coating for bicycle
Inventor: CHEN JR-CHENG
IPC: B05D7/14
Filed: 1997-12-02
Granted: 2001-01-21
Abstract: The present invention provides a method of applying light reflection coating for a bicycle, particularly a coating with good reflective effects. The method mainly comprises processing a raw material through pretreatment to form a membrane on the surface of the raw material; sequentially applying a mirror finish treatment, an adhesion treatment, a reflective treatment, a surface layer treatment and a post treatment, to successively spray-coating an ultra-bright base layer of a transparent resin which is adhered with a layer of dry-powder-type reflective particles, and to spray-coating a colored or colorless transparent face paint for the operation of attaching a label and coating of gold oil. Therefore, the method of uniformly adhering the dry-powder-type reflective particles on the surface of the transparent resin enables the reflective particles to be sequentially arranged in order without the problem of overlapping or over-sized gaps. Furthermore, the colorless or colored transparent face paint can form a natural or colored color during reflection. Therefore, the reflective particles according to the present invention, besides exhibiting good and multi-color reflective effects without the reflective light being obstructed or scattered, can increase the practicality and safety in use.

Title: Method for forming pipe end assembly
Inventor: Xu zi-sheng
IPC: B21D39/04
Filed: 1997-12-08
Granted: 1999-06-11
Abstract: The invention provides a method for forming a pipe end assembly, particularly to a process without soldering and multiple-step processing, which essentially comprises a single pressing and extruding process to assemble an end assembly having a housing on the periphery of a pipe body; in which the upper and lower of the housing on the pipe body separately form an expansion ridge and an annular protrusion at the initial stage of processing. During the intermediate stage, the annular expansion continue to grow thereby forming an annular flange. The pipe body between the expansion ridge and the assembly also shows an annular protrusion. During an end stage, the annular protrusion merges with the expansion ridge enlarged through outwardly rolling, thereby forming an insertion annular ring and fastening the pipe end assembly between the insertion annular ring and an annular protrusion, so as to complete the single pressing and extruding process, and greatly reducing the working process and cost.
