    摘要: In halftone imaging using rotated halftone dot cells, the determination of correspondences between microdots and threshold matrix cells is simplified by leaving the threshold matrices which overlie each halftone dot cell unrotated. Threshold decisions for each microdot in a given horizontal row of a grid proceed in sequence. Each increment along a microdot row within a halftone cell is a unit increment along a horizontal axis of the threshold matrix. Hence, within each halftone cell, two integer additions are sufficient to derive an address of the threshold matrix cell associated with a microdot given the address of the threshold matrix cell associated with the previous microdot.

    摘要: A locking differential comprising a differential carrier1 housing a pair of bevel gears 2, 3 and at least one pinion gear 4 which meshes with the pair of bevel gears, a locking ring 6 positioned within the differential carrier1 between the carrier and one of the bevel gears and splined to the carrier 1 at 7 and 8, locking teeth 9 on the locking ring 6 and corresponding locking teeth 10 on the bevel gear 3, an annular cylinder 12 formed in the carrier 1 and receiving a piston 11 and seal 11 a, the piston 11 being integral with the locking ring whereby the charging of the cylinder 12 with compressed air causes the locking ring 6 to move into its locking position with the teeth 9 engaging the teeth 10 against the action of springs 13 to lock the differential. The locking ring is located within a shaped cover plate C which closes the differential carrier 1 and provides bearing support for the bevel gear 3.
