Abstract: A macro pixel is provided. The macro pixel includes at least two color pixel elements. Each color pixel element includes a photoreceptor that in response to receiving light, generates an output signal that is indicative of the quantity of light photons of a color are received. Each of the color pixel elements are configured to receive a corresponding color. The photoreceptor of each color pixel element has a geometry and a responsivity to light that is a function of the geometry of the photoreceptor such that the responsivity of the output signal of the photoreceptor to the corresponding color is controllable by changing the geometry. The geometries of the photoreceptors are selected so that a predetermined relative sensitivity to each color is obtained.

Abstract: A method for hardening a coating of an object, more particularly a car body. A conveyor system moves the object to the proximity of a radiator and moves it away from said radiator with at least one transport cart that can be translationally moved on at least one running surface. A support frame for the object is fixed to the transport cart in order to rotate or pivot the object about a rotational or pivoting axis extending crosswise relative to the translational movement and independently thereof so that all areas of the surface can be exposed to approximately the same amount of radiation.

Abstract: An oven assembly for drying paint on a product transported by a conveyor includes a plurality of modules positioned in a generally abutting relationship. Each of the modules includes a roof, side walls, and a floor having a length and a width. The floor is formed from abutting floor panels reinforced by a plurality of support members spaced along the length of the floor and having a length greater than the width of the floor. The side walls include an inner side wall panel disposed in an overlapping relationship with the floor and a side wall cladding panel supported by the support members along the width of the floor thereby concealing thermal insulating material disposed between the inner side wall panel and the side wall cladding panel.

Abstract: A varnish oven (10), including a preheating station (12), a temperature homogenization station (14), a varnish application station (16), a varnish curing station (18), a cooling station (20), a conveyor system (24) and a control system (38). The conveyor system (24) moves parts through the oven. The parts start at the preheating station (12) where portions of the part are raised to an appropriate temperature for varnish application. The parts then move to the temperature homogenization station (14) where the temperature is maintained at an appropriate level. Varnish is applied to the part in the varnish application station (16) and is cured in the varnish curing station (18). Finally the part is cooled in the cooling station (20). The control system (38) varies the temperature of the preheating station (12), the temperature homogenization station (14), and the cooling station (20) to maintain part temperature upon stoppage of the conveyor system (24).

Abstract: Radiant emitting walls enclose opposite sides of a central combustion chamber in an oven where coated objects to be dried are placed or passed. The radiant emitting walls generate primarily infrared radiation and have a nonuniform temperature distribution so that the temperature of the lower portion of the oven can be selectively adjusted to be significantly higher than the temperature of the upper portion. An insulated outer housing surrounds the radiant walls and defines combustion chambers each having a linear burner which runs substantially the entire length of the radiant emitting walls. The lower portions of the radiant emitting walls receive energy primarily from radiation from the linear burners and the upper portions of the radiant emitting walls receive energy from primarily radiation from the interior radiant emitting surfaces of the insulated outer housing and convection from the linear burners.

Abstract: Apparatus for assisting the drying of a surface, for example a panel of a motor car, after it has been painted, in particular with a water-based paint coat, takes the form of at least two air movers, supported upon a structure and spaced apart in a generally horizontal direction. The air outlets of the air movers are directed away from each other at an angle of between 4 and 30 degrees. The apparatus may be mounted on a flat pedastal base for sliding convenience.

Abstract: An oven has heating units to dry the paint on a freshly painted automotive vehicle. Each heating unit has infra-red tubes mounted on a frame. A reflector plate having a reflecting surface is provided behind the frame. The frame is mounted for swinging movement from an operative position adjacent to the reflecting surface of the reflector plate to an inoperative position allowing access to the reflecting surface to enable the reflecting surface to be cleaned. A quick acting latch is provided to releasably secure the frame in its operative position.
