A method and device for modifying optical system properties by means of a continuously multifocal profile, wherein said profile comprises a component for increasing the optical system focal depth and is calculated according to a fourth-order Zernike polynom. The aim of said invention is to avoid the eye base refraction and, for this purpose, said focal depth increasing component is also calculated according to the second-order Zernike polynom.

A cam shaft phase setter including a control valve for controlling the feeding and draining of a hydraulic fluid into and out of a pressure chamber which serves to adjust the rotational angular position of a cam shaft relative to a crankshaft of an internal combustion engine. The control valve includes a valve housing with an operating port to the pressure chamber and a reservoir port to a reservoir for the fluid. A valve piston is axially adjustable back and forth in the valve housing between a first position and a second position and includes an axial hollow space, a piston inlet for introducing the fluid into the hollow space, and a piston outlet which leads out of the hollow space and is connected to the operating port in the first position of the valve piston and separated from the operating port in the second position of the valve piston. An actuating unit is coupled to the valve piston for axially adjusting the valve piston. A coupling member protrudes through an axially facing closure wall which closes off the valve housing and couples the actuating unit to the valve piston. The valve piston includes a radial widening which is surrounded by a complementarily widened housing portion of the valve housing and to which the fluid can be applied in an axial direction pointing away from the axially facing closure wall in order to generate an axial pressure force. The widening is dimensioned such that the fluid acts on the valve piston with a pressure force of at least substantially equal size in both axial directions, despite the coupling member.

In the case of a screw having at least one thread (26) that is formed by a rolling process, especially a flat-die rolling process, whereby the thread (26) consists of two ridges of material (28a, 28b) which are shaped from a blank (12) by means of cold-forming during the rolling process in such a way that the thread has a closing crease (32) where the ridges of material (28a, 28b) meet each other, it is provided that the closing crease (32) is situated in the area of a flank (30a, 30b) of the thread (26).

This invention relates to an explosion pressure relief device with a wall and a framework fixing the wall. In the case of an explosion in a container to which an explosion pressure relief device is attached, such explosion pressure relief device serves to allow the pressure wave to escape at best greatly weakened.

This invention provides a color print control method of acquiring an optimum profile by a simple profile acquisition process in consideration of the clustering configuration. According to the color print control method of this invention, a printer manager (15) manages a combination of color printers as a virtual printer. A color setting manager (17) manages a color profile used for color matching in association with the virtual printer and output paper. A job controller (11) controls to accept a print job, whose destination is the managed virtual printer and which contains color matching settings, cause a rendering unit (18) to render the print job, acquire a profile for each virtual printer, and cause a color management processor (16) to perform color matching.

A window well cover that is universal to the extent that it will work on different sizes and shapes of window wells within a certain range for each size of window well cover produced.
