Title: Torque cell
Inventor: WULFF THOMAS
IPC: H04M1/18
Filed: 2004-05-07
Abstract: A hand held mobile terminal (100) includes at least one torque cell for facilitating a torsionally stiff housing structure. The torque cell includes a plurality of first locking members (150) located around a perimeter of a first housing (110) and a plurality of second locking members (140) located around a perimeter of a second housing (120). The first and second locking members (150, 140) are slidably engageable with each other so as to create a plurality of interlocking joints (130) around the perimeter of the torque cell.  Accordingly, the torque cell structure provides several advantages over the conventional mobile terminal housing, such as: better torsional rigidity, simplified assembly, improved volumetric efficiency, reduced need for shock absorbing materials, lighter overall weight, decoupling of impact loads, and mitigation of stress concentrations.

Abstract: The present invention relates to a corrugated pipe (1) made of a thermoplastic material which comprises an inner pipe (2) and a corrugated outer pipe (3) connected therewith, whereby the profile of the outer pipe has first sections (4) with a first average diameter, second sections (5) with a second average diameter which is greater than the first average diameter, and flanks (6) between them which connect the first sections (4) with the respectively adjacent second sections (5). The geometric ratios of the corrugated pipe (1) according to the invention are designed in such a way that not only is a high rigidity given against compressive forces acting in radial direction on the corrugated pipe and a high flexibility relative to a deformation fo the corrugated pipe diagonally to its longitudinal axis, but at the same time a low weight in comparison to conventional corrugated pipes. As a result, the plastic required for the production is reduced and the handling of the corrugated pipe is facilitated during laying.

Title: Quartz gas discharge lamp providing photocatalytic oxidation
Inventor: WARD PATRICK
IPC: A62D3/00
Filed: 2005-11-16
Abstract: A germicidal quartz lamp (10; 110; 210) producing ultraviolet radiation having a sleeve coated (20; 120; 220) with a titanium dioxide (18; 118A, 118B; 218). Titanium dioxide (18; 118A, 118B; 218) is impregnated or embedded into the sleeve (20; 120; 220) and mechanically held.      Ultraviolet radiation having a wavelength of approximately 254 nm generated by the germicidal quartz lamp causes hydroxyl radicals to form on the titanium dioxide surface 18; 118A, 118B; 218). The hydroxyl radicals act as a powerful oxidizing agent that destroys pollutants. In one embodiment, different densities of the titanium dioxide (118A, 118B) coating are formed along the longitudinal length of the quartz lamp. A longitudinal portion (118C) of the quartz lamp may be free of any titanium dioxide coating permitting the ultraviolet radiation to pass therethrough creating a germicidal effect. The titanium dioxide may be heated to a temperature above the melting point of the sleeve to create the mechanical bond. The present invention is useful in the commercial food industry or for consumer use.

Title: A process for catalytic hydrocarbon recombination
Inventor: DING RANFENG
IPC: C10G35/04
Filed: 2004-07-02
Abstract: The present invention discloses a method for recombining catalytic hydrocarbons, which is fed onto the main catalytic fractional column for fractionating to get gasoline, diesel and a medium fraction. The medium fraction or the mixture of medium fraction and gasoline fraction is divided into aromatics and nonaromatics after the processing of aromatics extraction.  Then the aromtics is fractionated to get high octane value gasoline, which is blended with the former gasoline fraction to increase its octane value, on the other hand, the nonaromatics is fractionated to get diesel, which is blended with the former diesel fraction to increase its cetane value and yielding.  Compared with the prior art, the method with less investment and lower production cost is not limited by raw material and also can increase the final production items.
