Abstract: The invention relates to a method for the production of spectacle lenses from raw lenses prefabricated in a non-cutting manner. The raw lenses have a front side that is not to be reworked and an opposing back side to be reworked with a CNC machine, which sides have at least one optical focal point in common. In order to rework the back side a prescription surface is calculated on the basis of a prescription describing a visual error and of the geometry of the front side.  This surface forms a prescription lens in common with the front side, the focal points of which lens correct the visual error.  The front side is shaped in such a manner that it is a convex and rotationally symmetrical first freeform surface. This freeform surface is composed in a rotationally symmetrical manner about a middle axis by at least two spherical sections with different radii, whereby the spherical sections border each other tangentially. Furthermore, the spectacle lens has an optical center through which an eyeglass wearer looks when looking straight ahead (zero view direction).  The spectacle lens is manufactured in such a manner by an adaptation of the raw lens to an eyeglasses frame that the middle axis of the raw lens lies outside of the optical center of the spectacle lens.

Title: Portable instant hot water heater
Inventor: LONG NORRIS RICHARD
IPC: A23G3/00
Filed: 2003-07-25
Abstract: A portable instant water heater. Water is delivered to a base unit (22) of the instant hot water heater by a pump (26) that draws water from a reservoir (28) through a flow control valve (90). The water flows into a pre-heater (74) that wraps around a base of the burner and that is heated by the burner (52). Water is heated in a heat exchanger (82) and then exists the base unit through an outlet spout that swings out from the base unit to dispense water and that may be stored and locked into position in a handle for the base unit. The flow control valve (90) may lower the flow of water through the heat exchanger, so the water has more time to absorb heat and to get hotter. The base unit includes a single control knob (44) that turns on the pump (26) and the burner (52) and operates the flow control valve (90).
