Title: Contact lenses
Inventor: HALL JORDAN WILLIAM
IPC: G02C7/04
Filed: 2003-08-05
Granted: 2012-10-30
Abstract: The present invention provides a contact lens having an orientation feature that does not provide a prism optical distortion and can maintain a predetermined orientation of the lens on an eye. A contact lens of the invention comprises an anterior surface and an opposite posterior surface. The anterior surface includes a vertical meridian, a horizontal meridian, a central optical zone, a blending zone extending outwardly from the central optical zone, a peripheral zone surrounding the blending zone, and an edge zone circumscribing and tangent to the peripheral zone. The presence of the blending zone ensures that the peripheral zone, the blending zone and the central optical zone are tangent to each other. The peripheral zone has a surface that, in combination with the posterior surface, provides a lens thickness, in the peripheral zone, which is characterized by having a lens thickness which increases progressively from the top of the lens downwardly along each of the vertical meridian and lines parallel to the vertical meridian until reaching a maximum value at a position between the optical zone and the edge zone and then decreases to the edge of the edge zone; or alternatively by having a mirror symmetry with respect to a plane cutting through the vertical meridian, by having a substantially constant thickness in a region around the horizontal meridian and by having a thickness which decreases progressively from the horizontal meridian to the top or bottom of the contact lens along each of the vertical meridian and lines parallel to the vertical meridian.

Title: Steering damper and backup lock beam attachment
Inventor: RAMSEY JOHN
IPC: B62D61/12
Filed: 2003-10-10
Granted: 2008-12-09
Abstract: A steerable lift axle/suspension system (10) for a heavy-duty vehicle such as a semi-trailer or a straight truck, includes a pair of steering dampers (22) and a backup lock (23). The steering dampers (22) minimize shimmy of the steerable wheels during over-the-road operation of the vehicle, and straighten the wheels on such steerable axle/suspension systems having a lift feature (21) when the system is raised. The backup lock (23) secures the wheels in a straightened position when such liftable systems are raised and the vehicle is backing up, to minimize vehicle handling problems. The steering dampers (22) and backup lock (23) are mounted at a location off the axle tube (41) of the axle (14) and on the axle/suspension system beams (12), to eliminate stress on the axle (14) that would otherwise be caused by welded attachment of such components to the axle tube (41), thereby enabling use of a less robust, more lightweight axle tube (41).

De tels matériaux résistant à l'eau sont caractérisés par des propriétés accrues de barrière d'humidité. Les compositions présentent un faible indice d'iode (compris entre 2-5), et des points de fusion de l'ordre de 120-185 degrés F (point de goutte Mettler). La cire comprend un triglycéride dont les acides gras sont principalement des acides stéariques (en C¿18?). La composition est utilisée comme additif dans la fabrication de plaques de plâtre résistant à l'eau.

Title: Cuve de filtration et procede permettant d'obtenir un systeme de compresseur a gaz rotatif
Inventor: KROGUE JOHN A
IPC: F01C21/04
Filed: 2003-11-12
Granted: 2009-03-10
Abstract: L'invention concerne une cuve de filtration destinée à être utilisée avec un compresseur rotatif à vis. Ladite cuve reçoit un mélange de liquides/gaz comprimé en provenance du compresseur. La cuve fait appel à une région d'éjection tourbillonnaire constituant un premier étage pour éliminer des liquides en vrac par l'intermédiaire d'un mouvement circulaire qui impose des forces centrifuges sur le mélange de gaz et de liquides. Une région de coalescence située au-dessus de la région de vortex d'éjection reçoit les fluides relativement plus légers et permet de séparer n'importe quels liquides entraînés restants dans les fluides. Le refoulement de l'unité de filtration est un gaz comprimé sensiblement dépourvu de liquides. Le rejet de liquides, dans le cas d'huile de graissage peut être recyclé vers le compresseur pour un autre cycle.

Title: Oil preheater for a combustion system
Inventor: BECHARD RYAN
IPC: F23Q3/00
Filed: 2004-05-25
Granted: 2012-01-31
Abstract: A device and method of preheating oil in a combustion system that uses a heated liquid to convey heat energy to oil. The device is made of a thermally conductive material which has a passageway for oil and a passageway for a heated liquid. Heat energy from the heated liquid con~ductively transfers to the oil within the device. This method of preheating oil for combustion eliminates carbon creation and minimizes oil preheat temperature fluctuations thereby sig~nificantly lowering the cost and maintenance to operate a multi oil combustion system.
