Title: Dispositif de purge anti-calaminage pour injecteur de carburant
Inventor: PROCIW LEV ALEXANDER
IPC: F23K5/18
Filed: 1999-04-19
Granted: 2008-08-26
Abstract: L'invention se rapporte à un système de purge à air conçu pour empêcher la formation de calamine dans des injecteurs de carburant de turbines à gaz, et notamment dans les organes de pulvérisation mécanique dotés d'orifices relativement petits d'un injecteur primaire de carburant. Ledit système de purge à air est activé lors de l'arrêt du moteur de façon à évacuer en continu de l'air de refroidissement par les orifices des injecteurs pendant une période de purge prolongée après ledit arrêt, par exemple pendant 1 heure à une heure et demi. Une soufflante, alimentée par batterie et reliée à la tuyauterie de carburant, force l'air de refroidissement à passer dans l'injecteur jusqu'à ce qu'un commutateur à thermocouple désactive la soufflante lorsque la température détectée dans l'injecteur est inférieure à 150  DEG F. A cette basse température, la formation de calamine ne se produit pas et, lorsque le moteur fonctionne, l'efficacité de la combustion permet de minimiser le calaminage.

Abstract: Une matière plastique alvéolaire améliorée comprend une mousse d'uréthane qui est le produit de réaction d'huile de soja, d'un isocyanate et d'un agent de réticulation. L'huile de soja remplace le polyol qui est en général spécifiquement utilisé dans la production des uréthanes. Etant donné que le polyol remplacé est un produit pétrochimique, l'utilisation d'une matière renouvelable et respectueuse de l'environnement telle que l'huile de soja est extrêmement intéressante. En outre, les matières plastiques possédant plusieurs qualités finales peuvent être formées à l'aide d'une seule huile végétale. Hormis les mousses alvéolaires il est possible de former des élastomères plastiques solides.

Abstract: A tree felling and shaping apparatus is provided with a fully powered and controllable link system which links a tree processor head to a boom that is in turn mounted to a vehicle. The link system includes two powered pivoting joints and a rotary coupling of up to 360° disposed therebetween. Such a combination provides a great convenience for the manipulation of the tree felling and shaping apparatus, not only permitting a maximum angular adjustment of the tree processor head for all directional orientations whether the head is in an upright position for felling trees or the head is in a recumbent position for processing trees, but also performing a universal joint function to freely suspend the tree processor head from the boom without using a conventional uncontrollable universal joint. The present invention improves maneuverability of the tree felling and shaping machines and thereby increases work efficiency.

Abstract: A method and apparatus for controlling the operating speed of a manufacturing facility is disclosed. It includes determining a desired operating speed that is dependent on at least one economic variable. The variable vary with the operating speed. Also, the operating speed is adjusted (if necessary) in response to the determination. Preferably the control is closed loop and includes determining a current operating speed (101) and comparing the current operating speed (107) to the desired operating speed (103). The operating speed is controlled in response to the comparison (109). The economic variable is preferably a cost of manufacturing, and/or manufacturing inflows, and/or manufacturing outflows. The economic efficiency is dependent on one or more economic variables that vary with operating speed. The current economic efficiency of the facility is obtained along with information on the business transactions that affects the economic variables. The economic efficiency of the facility with the proposed transaction, leaving the remaining variables constant is calculated. Then, the result is displayed to the end user.

Abstract: An integrated joint assembly fastener is described for removably securing two adjoining members together along flat mating surfaces. A housing is provided with an off-center circular bore in which a rotatable element is held captive.  The bottom end of the rotatable element has an offset connecting post which extends perpendicular to a slit provided in a rear sidewall of the housing.  Stationary wedges on the housing front project from opposite side of the slit.  A pair of connecting dowel head sections project from the front opening and are engaged by the offset connecting post of the rotatable element. The dowel head sections have a gripping ridge section at a free end and an inclined abutment formation for sliding engagement against the wedges. By rotating the rotatable element, the gripping ridge sections of the dowel head are pulled back and wedged outwardly, laterally. Displacement inwardly towards the housing front causes each gripping head section to engage within the materials in bore of the adjoining member and to pull back and tighten the members together.

Abstract: Dominant negative alleles of human mismatch repair genes can be used to generate hypermutable cells and organisms. By introducing these genes into cells and transgenic animals, new cell lines and animal varieties with novel and useful properties can be prepared more efficiently than by relying on th e natural rate of mutation. These methods are useful for generating genetic diversity within immunoglobulin genes directed against an antigen of interes t to produce altered antibodies with enhanced biochemical activity. Moreover, these methods are useful for generating antibody-producing cells with increased level of antibody production.

Title: Urine assay for ovarian reserve
Inventor: BATEMAN PAUL NORTH
IPC: G01N33/558
Filed: 2002-02-14
Granted: 2010-09-07
Abstract: It has been found that a urine test for ovarian reserve can be provided which is equivalent in sensitivity to current laboratory methods which determine ovarian reserve based on FSH levels in serum. A lateral flow device for indicating ovarian reserve is disclosed. The device has an application zone for receiving a urine sample, a labelling zone containing label which binds to FSH in the sample, and a detection zone where FSH-bound label is retained. The detection zone has a threshold value which corresponds to a serum FSH level of between 5-20 mIU/ml (e.g. 10mIU/ml). A test result above the threshold value indicates diminished ovarian reserve.
