Title: A cleaning fluid heating reservoir and motor assembly for a range hood
Inventor: YEUNG PETER
IPC: F24C15/20
Filed: 2003-05-07
Abstract: A cleaning fluid heating reservoir and motor assembly for a range hood having a motor housing enclosure mounted within the enclosure defined by the hood body.    The heating reservoir is shaped and dimensioned to be in abutment with the motor which in turn is mounted within the motor housing. The reservoir may occupy space between the top of the motor and the hood body, between the perimeter of the motor and a fan attached to the motor, or between both. Conduits connected to inlet and outlets to the heating reservoir pass through side of the motor housing to an intermediate reservoir located within the range hood body.

Abstract: An accommodating intraocular lens including a higher diopter positive intraocular lens and a lower diopter negative intraocular lens. The positive intraocular lens includes a positive optic portion having an outer peripheral edge and two or more polyurethane elastomer flexible attachment components.  The negative intraocular lens includes a negative optic portion having an outer peripheral edge and two or more polyurethane elastomer flexible attachment components. Each flexible attachment component is durable and formed to have specific flexibility characteristics so as to be less resistant to bending in a plane generally parallel to an eye's optical axis than in a plane generally perpendicular to the eye's optical axis. The subject durable accommodating intraocular lens enables axial displacement of the positive optic portion with respect to the negative optic portion along the eye's optical axis under a compression force. The flexible attachment components are durable to allow dependable flexation thereof millions of times during a patient's lifetime. Through this flexation of the flexible attachment components and axial displacement of the positive optic portion with respect to the negative optic portion, accommodative effects are maximized to achieve multi-distance visual imaging.
