IPC: F23L7/00
Filed: 1994-03-08
Granted: 1999-09-07
Abstract: An object of the present invention is to overcome the disadvantages of a conventional combustor having a fuel-air premixing nozzle wherein variation in combustion rate resulting from variation in the fuel concentration of the premixed gas cause variation in flame length and may eventually lead to the development of combustive vibration.      This invention provides a combustion method and combustor which is characterized in that a fluid (8) containing no fuel is fed between a premixed gas layer (2) formed by injecting a premixed gas through a premixing nozzle (1) and a hot gas layer (5) formed from a portion of the hot gas resulting from the combustion of the premixed gas, the hot gas layer (5) circulating or staying in a region downstream of the outlet of the premixing nozzle (1).

Abstract: Lampe de poche munie d'une lampe de signalisation, pouvant être miniaturisée et facile à utiliser. Un corps cylindrique coulissant (20) est inséré sur la partie externe supérieure du logement (10) destiné à recevoir une ou plusieurs piles. Lorsque le corps coulissant (20) est déplacé dans une direction verticale, toute la lampe de poche se déploie ou se contracte. Une plaque incolore transparente (24) et une plaque réfléchissante (25) sont aménagées dans une première partie cylindrique (21) pour former une lampe d'éclairage, de sorte que lorsque toute la lampe de poche se contracte, une ampoule (40) se place dans cette première partie cylindrique (21), de manière à ce que la lampe de poche puisse servir de lampe d'éclairage verticale (voir le schéma). Lorsque la lampe de poche est entièrement déployée, la lumière diffusée provient de la seconde partie cylindrique (22), conçue pour servir de lampe de signalisation, dont la paroi est fabriquée en plastique rouge transparent, ce qui permet d'utiliser la lampe de poche comme lampe de signalisation. La seconde partie cylindrique (22) comprend une rainure interne (22c) dans laquelle s'insère l'élément de contact en saillie (13c) d'un interrupteur rotatif (13). La rotation du corps coulissant (20) permet de faire passer l'interrupteur rotatif (13) en position marche/arrêt pour allumer ou éteindre l'ampoule (40).

Title: Data analysis method for use with fluorescent bacterial sensors
Inventor: BERNDT KLAUS W
IPC: G01N21/78
Filed: 1995-01-19
Granted: 2001-05-15
Abstract: A method of analyzing the data provided by a fluorescent chemical sensor calculates a ratio based on the AC and DC components of the emission from the chemical sensor. This ratio, or the emission modulation, will change should bacterial growth be ongoing in the vial. The calculated ratio is compared to a desired value. The desired value is selected to focus the operation of the system into a high resolution area for the sensor. If the calculated and desired ratios differ, then the frequency of the excitation radiation is changed until the calculated and desired ratios are effectively equal. At that time the adjusted frequency is measured. By focusing the desired ratio into a high resolution area, and adjusting the frequency until the system reaches that ratio one ensures that all readings are performed at a high resolution area of the sensor. The adjusted frequency is utilized to provide an indication of whether the particular vial is experiencing bacterial growth. This adjusted frequency is a linear function of changing conditions within the vial. Several methods of achieving the above features of this invention are disclosed. By utilizing this method, one provides an easily interpreted indication of whether a particular fluorescent chemical sensor is in a vial which is experiencing bacterial growth.

Filed: 1996-01-31
Granted: 2003-07-08
Abstract: The present invention relates to a non-mandrel method of manufacturing a flexible, kink-resistant hose capable of regaining an original shape after crushing. This process comprises the extruding of a continuous length of an uncured elastomeric tube provided with an adhesive layer and formation of a hose reinforcement layer or jacket around this elastomeric tube. The jacket comprises a tubular sleeve formed by means of a warp yarn running in the longitudinal direction of the tubular sleeve and a weft yarn running in the transverse direction of the tubular sleeve. The weft yarn is interwoven with the warp yarn, and it comprises a combination of a multi-filament weft yarn alternating with a mono-filament weft yarn. The mono-filament weft yarn is characterized by being of extreme stiffness and rigidity, which enables the hose to retain its round shape by resisting collapsing and crushing.

Abstract: A resealable package having a label applied over an opening into the package. The label has a pressure-sensitive adhesive, and is repeatably peelable from the package body and reappliable thereto. Full peeling of the label from the body is inhibited by a portion of the label co-acting with a portion of the package body. In one form of the invention, the label has cuts on opposite sides with an uncut portion therebetween, and the inhibiting of peeling is due to puckering of the package and the label when the label is peeled back to the cuts. In a second form of the invention, the package includes tabs or fragments which adhere to the label, with the peeling being inhibited when un-cut portions of the tabs or fragments are reached.
