Patent number: 7891175Abstract: An internal combustion engine in which an SOx trap catalyst able to trap SOx contained in exhaust gas is arranged in an engine exhaust passage upstream of an NOx storing catalyst. The SOx trap catalyst is strengthened in basicity compared with the NOx storing catalyst to an extent so that when the temperature of the SOx trap catalyst is in the temperature range at the time of ordinary operation, that is, substantially 150° C. to substantially 400° C., the NOx purification rate by the SOx trap catalyst becomes less than substantially 10 percent of the NOx purification rate by the NOx storing catalyst. When NOx should be released from the NOx storing catalyst, the air-fuel ratio of the exhaust gas flowing into the SOx trap catalyst is temporarily switched from lean to rich.Type: GrantFiled: March 23, 2007Date of Patent: February 22, 2011Assignee: Toyota Jidosha Kabushiki KaishaInventors: Kohei Yoshida, Kotaro Hayashi

Patent number: 7891189Abstract: The invention relates to a liquid working substance flow, the pressure of said flow being increased and the flow itself being subdivided into a first partial flow and a second partial flow. The first partial flow is partially evaporated with heat from a heat source, and the second partial flow with heat from a working substance flow with a low surface tension. The two partial flows are then combined and produce a gaseous working substance flow with heat from the heat source. The surface tension of said gaseous flow is reduced and the energy thereof converted into a usable form. The working substance flow with a low surface tension is condensed, thus producing the liquid working substance flows. According to the invention, the first partial flow and the liquid working substance flow are essentially at the same temperature. In this way, the heat of the heat source can be better used, thus increasing the efficiency of the cycle.Type: GrantFiled: July 7, 2004Date of Patent: February 22, 2011Assignee: Siemens AktiengesellschaftInventors: Matthias Böttger, Jörg Lengert

A chalcogenide glass having the composition Ge(5?y)As(32?x)Se(59+x)Te(4+y) (0?y?1 and 0?x?2) is substantially free from crystallization when it is heated past the glass transition temperature Tg or drawn into optical fibers. A process for making the thermally stable chalcogenide glass includes purifying the components to remove oxides and scattering centers, batching the components in a preprocessed distillation ampoule, gettering oxygen impurities from the mixture, and heating the components to form a glass melt. An optical fiber formed from the chalcogenide glass is substantially free from crystallization and exhibits low signal loss in the near-infrared region, particularly at wavelengths of about 1.55 ?m.Type: GrantFiled: June 18, 2010Date of Patent: February 22, 2011Assignee: The United States of America as represented by the Secretary of the NavyInventors: Vinh Q Nguyen, Jasbinder S. Sanghera, Ishwar D. Aggarwal

Patent number: 7891217Abstract: Glass can be synthesized and deposited at a high rate by the inside CVD method using a plasma burner in a manner such that unconsolidated portions or bubbles are little generated. The method includes a step of depositing a glass film on the inner wall surface of a starting pipe. In a first aspect, temperature the pipe is controlled not to exceed (1800 +100xd)° C., a temperature of (1100 +100xd)° C. or higher being continued for 20 seconds or more at each point of the pipe, where d (mm) represents the wall thickness of the pipe. In a second aspect, the burner includes at least two inlets and has an inner diameter of 80 mm or more, and the deposition step is performed in the relationship, 150 mm/s <(Total flow rate of the gases introduced into the burner)/(Sectional area of the burner) <600 mm/s.Type: GrantFiled: October 20, 2005Date of Patent: February 22, 2011Assignee: Sumitomo Electric Industries, Ltd.Inventors: Tetsuya Nakanishi, Masaaki Hirano

Patent number: 7891219Abstract: A lock guard protects a padlock with a shackle and the ends of a securing connector. The device comprises a five-sided housing with an open bottom. Two opposing sides of the housing have opposing openings therethrough for inserting the ends of the securing connector. Inside the housing is a retaining tab having an opening therethrough dimensioned to receive the end of the shackle. The housing can also contain an abutment providing a surface against which to drive the top of the shackle when locking the padlock within the lock guard. When the retainer tab is vertical, the top edge of the hole in the retainer tab can act as an abutment.Type: GrantFiled: September 14, 2009Date of Patent: February 22, 2011Inventor: Roy E. Gogel

Patent number: 7891220Abstract: A lockable container comprising a lock portion and a container is provided. The lock portion has a first part and a second part, wherein the first part has an opening component and at least a lock mechanism, the second part has at least a latch driven by the opening component. The container fits the second part. The container has at least an inner space and a wedge corresponding to the latch. The lock mechanism restricts a displacement of the opening component when the lock mechanism is locked. The lock mechanism releases the opening component when the lock mechanism is unlocked.Type: GrantFiled: March 30, 2009Date of Patent: February 22, 2011Assignee: Sinox Company Ltd.Inventors: An-Ting Yen, Chi-Chang Tsai
