Abstract
Lack of balance of a crank mechanism, which reciprocates a ledger having one or more guides for one or more cigarette rods or filter rods each issuing from a maker and being subdivided into a row of cigarettes or filter mouthpieces, is at least partially counteracted by at least two counterpoises one of which orbits about the axis of the crank mechanism in a first direction and the other of which orbits, in a second direction counter to the first direction, about a second axis laterally offset relative to the axis of the crank mechanism. A third counterpoise can be mounted for orbital movement about the axis of the crank mechanism and, if utilized, is angularly offset relative to the first counterpoise. The prime mover for the crank mechanism orbits the first and (if provided) third counterpoises in the first direction, and (e.g., by way of a V-belt) the second counterpoise in the second direction. An orbiting knife reciprocates with the ledger and severs the rod or rods during movement with the ledger in the direction of forward movement of the rod or rods.
Abstract
There is provided an apparatus for measuring uniformity and dynamic balance of a tire, comprising: a spindle rotatably supported in a rigidly-supported spindle housing, said tire being fixedly mounted on said spindle, said spindle being rotated when measurement is performed; and at least one piezoelectric force sensor mounted on a surface of said spindle housing, said at least one piezoelectric force sensor detecting a force generated by rotation of the tire as said spindle is rotated.
Abstract
There is disclosed an automatic white-balance correction method for digital camera, which divides a captured picture into multiple sampled regions for performing a white-balance correction. The image data of the captured picture is transformed form RGB format to YCrCb format. Then, the mean values of Y, Cr, and Cb are calculated for each sampled region based on the multiple sampled regions. Finally, Cr and Cb are used as two coordinate axes to define four quadrants, and the values of Cr and Cb of each sampled region are used to determine a corresponding quadrant for each sampled region, thereby determining a correction direction based on the number of sampled regions in each quadrant. |
