Title: Lift enhancing tip vortex generation technology
Inventor: MCCARTHY PETER THOMAS
IPC: B64C23/06
Filed: 1995-07-18
Abstract: Methods for using tip generated vortices to improve performance of foils. These methods include generating substantially streamwise beneficial vortex (74) near the outboard end (60) of a foil (82). This beneficial vortex (74) spins in the opposite direction of an induced drag vortex (62), and is used to create an upwash field (76) which neutralizes induced drag by deflecting the flow behind the trailing edge (56) at an upward angle. Upwash field (76) causes the lift vector (118) on the foil (82) to tilt forward, thereby creating a forward directed force of induced thrust upon the foil (82). Beneficial vortex (74) is also used to contain and compress the high pressure field existing along the attacking surface of the foil (82). Embodiments include a twist (66) along the span of a foil (82b), an anhedral tip droop having a divergent axis of droop curvature (86), a movable vortex flap (102), a cone shaped vortex flap network (162). Methods for reducing overall tip vorticity are disclosed.

Title: Dynamic and thermal mechanical analyzer
Inventor: REED KEVIN J
IPC: G01N3/18
Filed: 1997-02-28
Abstract: A dynamic and thermal mechanical analyzer incorporating a slide driven vertically in an air bearing guidance system with a large displacement capacity, very low friction and low mass. The position of the slide is measured by digitizing and interpolating two quadrature output signals generated by an optical encoder with very high spatial resolution and a long stroke. A force is applied to the slide using a linear permanent magnet motor with high force, high force linearity and low sensitivity to temperature variations. Position signals derived from the digitized and interpolated quadrature output signals are analyzed as a function of the applied force to calculate viscoelastic properties of a sample of material.

Abstract: Un système de commande du fonctionnement d'une machine télécommandée comporte un capteur qui détecte l'orientation angulaire d'une articulation et la convertit en une longueur requise de l'actuateur linéaire (piston et cylindre) pour obtenir une longueur ponctuelle. Un circuit de commande présente en entrée une valuer de position souhaitée pour l'articulation et le système définit la longueur de l'actuateur linéaire (ou le flux qui lui est destiné) pour que l'articulation occupe la position souhaitée en fonction d'une comparaison des longueurs souhaitée et réelle de cet actuateur, et il règle cette longueur (ou ce flux) selon celle (ou celui) nécessaire pour déplacer cette articulation vers la position souhaitée, c'est-à-dire qu'il augmente la longueur de cet activateur jusqu'à celle requise pour obtenir le déplacement souhaité de l'articulation. Une autre solution consiste à comparer les positions réelle et souhaitée dans un comparateur (soustracteur ou sommateur), et le signal résultant, modifié en fonction de la position réelle et de l'équipement à commander et du signal modifié, sert à définir la longueur ou le flux requis pour l'actuateur.
