Abstract: A fuel-fired air heating furnace is provided with NOx reduction apparatus associated with a plurality of combustor tubes forming a portion of the furnace heat exchanger section. Inshot-type fuel burners are spaced apart from and face the open inlet ends of horizontal combustion sections of the combustor tubes. The NOx reduction apparatus includes a plurality of NOx reduction members formed from a metal rod material, and a mounting plate having a row of spaced apart pairs of mounting holes therein. Each NOx reduction member has an elongated, generally U-shaped configuration, with a closed inner end, an open outer end, and a spaced pair of corrugated leg portions extending between such inner and outer ends. The NOx reduction members are installed in a parallel relationship on the mounting plate, with their closed ends facing in the same direction, by resiliently deflecting the leg portions of each member toward each other, inserting the outer leg ends in one of the mounting plate hole pairs, and then releasing the legs. With the NOx reduction members secured to the mounting plate in this manner, they are simultaneously inserted closed ends first into their associated combustor tubes, and the mounting plate suitably supported adjacent the combustor tube inlets. The burners are then positioned to inject flames into the combustor tubes with the NOx reduction members positioned therein to operatively intercept the incoming burner flames.

Title: Films a appliquer pour surfaces a courbure complexe
Inventor: DAVIS KEITH J
IPC: G05B19/4099
Filed: 1996-06-05
Granted: 2005-03-22
Abstract: Des restrictions toujours plus rigoureuses concernant l'environnement rendent encore plus provocant le fait d'appliquer des revêtements par des procédés conventionnels tels que la peinture au pistolet à cause des solvants volatils et des pigments dangereux que la peinture renferme. La présente invention propose un autre procédé consistant à appliquer avec précision un revêtement sur une surface. Selon ce procédé, nous appliquons des films de courbure gaussienne constante sur des surfaces correspondantes de courbure comparable. Nous produisons les films à appliquer à l'aide d'une famille de moules de courbure gaussienne différente au lieu de réaliser un moule "par projection" sur la surface concernée pour former les films à appliquer, ce qui évite aussi de se heurter au problème des nervures, des plis ou des fentes que l'on connaît lorsque l'on essaye de recouvrir la surface avec des films à appliquer plats (plans).

Abstract: Optical amplifiers are typically disposed along the transmission path of an optical system. If a large number of optical amplifiers, e.g., eight, are so disposed, then it is likely that an appreciable level of so-called power divergence will occur among the optical signals forming a composite optical signal that traverses the path. Disadvantageously, when the composite signal is received at a destination and demultiplexed, a number of the demultiplexed optical signals will contain components of the other demultiplexed optical signals as a result of such power divergence. This problem is readily handled using a facility which greatly suppresses such components in a demultiplexed optical signal.

Inventor: RAMM-SCHMIDT LEIF
IPC: B01D1/22
Filed: 1998-01-22
Granted: 2006-03-21
Abstract: The invention relates to a heat exchange element (1) which is made up of a bag of a film material, such as plastic film, and to a heat exchanger made up of such heat exchange elements, the heat exchanger being suitable, for example, for the evaporation of effluents which contain solid matter, such as effluents from bleaching. The transfer of heat takes place in the bags (1) from a vapor condensing in the interior (3) of the bags to a liquid evaporating on their exterior surfaces (2). The forming evaporated vapor may be recycled via a compressor to the interior of the bags as heating vapor so that the heat exchanger will function as a distillation apparatus. According to the invention there is bonded inside the bag (1) a planar condensate-removal member, substantially narrower than the bag, for example, a circular disc (9) to which the forming condensate is arranged to flow and in which there is formed a hole (13) and at least one condensate outlet duct (8) leading to it, the film material of the bag being pierced in the area of the hole on each side of the condensate-removal member. In the heat exchanger, which has oppositely positioned bags (9) tied to form a pack, the condensate-removal members (9) are located one against another, and the apertures pierced in the film material form a condensate-collection duct common to them. The condensate-removal members being narrower than the bags enables the solid matter from the suspension being evaporated to be removed by falling through the spaces between the bottoms (10) of adjacent bags.

IPC: G06F12/109
Filed: 1991-11-12
Granted: 2000-05-09
Abstract: Method and means are provided for simulating a contiguous data space within a computer memory, and for placing and accessing data objects of various sizes within the simulated contiguous data space. Multiple, sub-data spaces are concatenated in such a way that each page and each sub-data space in the contiguous data space are uniquely identified.  Data objects are placed in the contiguous data space and at the first reference to a page of the data object, only the segment containing the referenced page in the contiguous data space is mapped to the database storage disk. Once a data space page is mapped, the operating system can read the page into memory without requesting a disk operation from the database manager. On modifying a page, if the database disk page location is changed, the contiguous data space page is re-mapped without changing the page address in the data space. Also, modified data pages are re-written to the database storage disk in an ongoing manner set by the user, instead of at intervals set by the operating system.
