Title: Silver-gas diffusion electrode for use in air containing co2 and a method for producing the same
Inventor: BECKMANN ROLAND
IPC: H01M4/86
Filed: 2005-07-09
Abstract: The invention relates to a method for the production of a gas diffusion electrode from a silver catalyst on an PTFE-substrate. The pore system of the silver catalyst is filled with a moistening filling agent. A dimensionally stable solid body having a particle size greater than the particle size of the silver catalyst is mixed with the silver catalyst. Said compression-stable mass is formed in a first calendar in order to form a homogenous catalyst band. In a second calendar, an electoconductive discharge material is embossed in the catalyst band, and heating takes places between the first and the second calendar by means of a heating device, wherein at least parts of the moistened filling agent are eliminated. The invention also relates to a gas diffusion electrode which is produced according to said method.

Abstract: Utilization of resources used to provide a service, and/or costs associated with providing system resources for a service, are tracked in a system where the available resources vary depending on a variety of conditions including resource utilization by other users. The methods are well suited for systems such as mobile communications systems, where the amount of resources and/or costs to a system of providing a service are dynamic and can change on a relatively rapid time scale. Resource unitization is tracked on a per subscriber basis. Service charges can be determined as a function of both the amount of resources consumed and the amount of data delivered, with the amount of resources being used to deliver a fixed amount of data units varying as a function of environmental and/or other conditions. Service charges are sometimes determined as a function of the impact of providing the service to a first user on other system users.

Title: A fresh keeper
Inventor: YANG SIMIN
IPC: F25D23/00
Filed: 2005-01-12
Abstract: A fresh keeper used in refrigerating apparatus comprises a lid ( 1 ), an outer drawer ( 2 ) and at least one inner drawer ( 3 ) which is contained in said outer drawer, a gap is formed between the outer drawer and the inner drawer such that said outer drawer ( 2 ), said inner drawer ( 3 ) and said lid ( 1 ) form a sealed space when they are in mounting state. The effect of heat preservation is improved due to the air insulating layer, thereby the temperature inside the fresh keeper is not easily influenced by the ambience and the temperature inside the fresh keeper is more stable. Because of the double-layer structure used in the invention, an air layer is formed. The pressure of the vapor in the air layer is much more than that of the inner drawer, thus it is difficult for the vapor in the inner drawer to diffuse into the air layer, and thereby the moisture in the inner drawer is ensured so that the humidity is kept to be a high value.

Title: Fiber optic temperature and pressure sensor and system incorporating same
Inventor: CHEN YUEHUA
IPC: G01L9/00
Filed: 2006-06-20
Abstract: A sensing system including a sensor having an enclosure that defines a chamber, a fiber optic segment extending from outside the enclosure into the chamber, and a sequence of optical processing elements within the chamber. The elements include a fiber Bragg grating, a polarizer, a side hole fiber, and a mirror. A light source is arranged to direct light to the sensor(s). A  spectral analyzer is arranged to detect light reflected back from the sensor(s). The fiber Bragg grating substantially reflects a first spectral envelope while transmitting the remainder of the optical spectrum to the polarizer and side hole fiber. The polarizer, side hole fiber, and mirror cooperate to return an optical signal within a second spectra! envelope. The characteristic wavelength of a peak in the first spectral envelope is highly sensitive to temperature and relatively weakly sensitive to pressure. The period of the optical signal within the second spectral envelope is highly sensitive to pressure and relatively weakly sensitive to temperature. The spectral analyzer measures these spectral components to simultaneously derive a measure of temperature and pressure that effectively compensates for temperature-pressure cross- sensitivity of the sensor(s).
