Abstract: On décrit un laser excimère ou d'ablation qui s'utilise pour couper des fils de chaîne sélectionnés d'une toile, par exemple, en particulier pour abouter les extrémités d'une toile de machine à papier en vue d'obtenir une bande sans fin. Pour projeter le laser, l'imagerie optique et le guidage électronique sont utilisés, et le faisceau laser peut être dirigé en bas vers un tube sonde (20) s'étendant à l'intérieur du tissu et formé de manière à écarter les fils pour permettre au laser de cibler un fil. Ce laser peut également servir pour rattacher des fils dans une deuxième étape du processus d'assemblage de la toile.

Abstract: In a tail tube seal structure of gas turbine, a U-shaped groove is provided at one side of a tail tube seal where a flange of a tail tube outlet is fitted, and a pi-shaped groove is provided at other side of the tail tube seal where a gas pass side flange end is fitted, thereby composing the seal of the connection area. Inclined cooling holes are drilled in the tail tube seal in addition to the cooling holes existing conventionally. The cooling air flows in from the inclined holes and cools the gas pass side of the groove due to the film effect. Therefore, the difference in thermal expansion between the groove and flange end is decreased, the wear of this area is decreased, and the reliability of the seal is enhanced.

Title: Child resistant lighter
Inventor: FAIRBANKS FLOYD B
IPC: F23Q2/28
Filed: 1999-10-15
Abstract: A child-resistant lighter includes an actuator (7) and a latch member (8) coupled thereto.  The latch member includes a finger actuation portion (92) and an integrally formed body portion (96) having a free end. In one embodiment, the latch member is pivotally coupled to the actuator. In an inoperative position, the free end of the latch member is aligned with a blocking surface (104) of the lighter body, preventing inadvertent lighting.  In an operative position, the free end of the latch member is pivoted out of alignment with the blocking surface so that the lighter can function. During pivoting, as the finger actuation portion moves in a forward direction, the free end moves in a rearward direction. The latch member may be disposed on the rear wall of the actuator or in a longitudinally extending channel in the actuator.

Title: Method and apparatus for forming rivet joints
Inventor: THOMPSON EDWIN E
IPC: B21J15/28
Filed: 2000-08-04
Abstract: A method and apparatus for forming rivet joints with a desired amount of clearance to allow pivotal motion of the parts interconnected by such joints. Parts to be riveted together are aligned with each other, and a rivet is placed into aligned holes. A parts clamp urges the parts and a preformed head of the rivet against a rivet support anvil to establish an initial condition. A parts support anvil is placed in a required position with respect to the rivet support anvil prior to formation of the second head on the opposite end of the rivet, to provide the desired amount of clearance. The parts support anvil is moved by pushing against a set of arched leaf springs to adjust their effective length, using a hydraulic motor controlled in response to an electrical signal from a transducer that measures movement of parts by the parts support anvil.

Abstract: Fuck The invention provides an IP QoS management mechanism for modern wireless networks to guarantee delivery of IP services with the required quality through the networks to customers. In order to realize IP QoS management in wireless networks, the invention provides a layered QoS management architecture which performs the QoS control over the entire communication protocol stack of a wireless network. The architecture consists of two levels of IP QoS management with an adaptation interface between them. These different functional and adapting levels are called, from top to bottom, Upper Layer QoS Management (ULQM), IP QoS adaptation (IQA), and Lower Layer QoS Management (LLQM). The ULQM is responsible for IP QoS management in the Upper Layers of a wireless network for end-to-end QoS delivery. In contrast, the LLQM takes charge of managing IP QoS in the Link Layer and Physical Layer of the network. To shield the LLQM from burdens caused by coping with application details from the Upper Layers, the IQA plays a role in buffering and adapting the QoS signaling flow from the Upper Layers to prevent it from directly entering into the LLQM without adaptation. Therefore, the IQA allows the ULQM and LLQM to work independently of each other. In addition to this functionality, the IQA also provides a link between the LLQM and the ULQM in the form of a QoS delivery path from the Upper Layers to the Link Layer and Physical Layer of the network to consistently provide an IP QoS management flow over a wireless link. The IQA sub-layer contains two entities. One is called the IP QoS Adaptation Control Function (IQACF), residing in the control plane of the communication protocol stack and the other is called the IQA Entity (IQAE), residing in the data plane of the stack.

Abstract: The present invention provides a gene Any-RF derived from an insect, having dormancy-control activity and biological cell-control function; a dormancy-control substance and a method for preparing the same; as well as a biological cell-control agent, which comprises, as an effective component, a physiologically active substance having a biological cell-control function and which never causes any antigen-antibody reaction in the living body.      The gene encodes for a protein having an amino acid sequence specified as Sequence No. 1 in SEQUENCE LISTING: Asp-Ile-Leu-Arg-Gly, whose C-terminal is amidated and having a molecular weight of 570.959. The physiologically active substance comprising such a gene is a peptide, which can be isolated and purified by adding an acid-methanol aqueous solution to Antheraea yamamai, triturating the resulting mixture, centrifuging the same and then treating the resulting supernatant in an HPLC system. The peptide permits the control of the dormancy of insects and is also useful as a biological cell-control agent, which comprises, as an effective component, such a peptide.
Patent CA-2328240-A1 (CA)
Inventor: NIESZCZUR KEITH J
IPC: F23C99/00
Filed: 1999-04-29
Abstract: A low NOx burner and related method are disclosed including the steps of supplying a first reactant stream and introducing a second reactant stream into the first reactant stream at a first point so as to produce co-flowing streams. This resulting fuel/oxidant stream is discharged into a furnace environment having inert combustion products substantially equilibrated to furnace temperature, so as to entrain the combustion products and mix them together with the co-flowing stream. The temperature of the co-flowing stream is increased by the entrained products until it ignites in a combustion region displaced from the first point. Thus ignition cannot occur until the reactant stream has been diluted by inert products of combustion, reducing both oxygen concentration and peak flame temperature, so as to suppress NOx production.

Abstract: A contactless programmable electrostatic RFID apparatus (101, 102) that is cost-effective, has high manufacturability, and can be easily packaged for a wide range of applications is presented. Under the present invention, following an exciter signal, a data reader/encoder (101) transmits a write mode data sequence to communicate to a transponder (102) whether to enter into write mode. The modulated write mode data sequence further provides instruction, data, and memory address information for the transponder to use in writing data into its memory. Conversely, the transponder interprets the absence of such write mode data sequence to mean that read mode is desired.  Accordingly, read mode is the default mode.
