IPC: H03M13/05
Filed: 1999-04-16
Abstract: A method for encoding an input data block (IDB) with a block encoder (TE). The block encoder is capable of processing consecutive coding blocks (CB) whose size has an upper limit (L CB ) which is smaller than the size of the input data block (IDB). The method comprises: (1) determining the length of the input data block (IDB) before encoding any of its data with the block encoder (TE); (2) dividing the input data block (IDB) to a plurality of segments (S 1  ... S N ) wherein all segments are of substantially equal size and no segment is larger than the upper limit (L CB ); and (3) processing each segment (S 1  ... S N ) with the block encoder (TE). If the last segment (S N ) is shorter than the remaining segments (S 1 , S 2 ...), fill bits (N FILL ) can be added to the last segment (S N ) such that its length equals that of the remaining segments (S 1 , S 2 ...).

[Class 83 (iii).] In a lathe driver or chuck for railway carriage or wagon wheels, slides b radially movable in a driving ring c are adjusted by a rotatable cam ring f having a cam surface m<1> for each slide. L-shaped pieces m secured to the slides engage cam slots n to effect a positive withdrawal. Wedge-shaped gripping jaws a are slidable circumferentially along inclined surfaces a<1> of the slides to increase the grip if the work o tends to slip and are normally retained in the retracted positions by springs. The ring c is attached to a face-plate d which also carries a central sleeve g with projections h, the action being such that as the cam ring f is rotated by a tommy bar &c. to release the work, the projections h engage projections i on the cam ring to centralize the jaws a and ensure the withdrawal of each jaw, but on gripping the work the projections ride away from each other as shown in the Figure to allow the jaws and cam ring to float and grip the work evenly. The movement of the jaws along the inclined surfaces a<1> is limited to prevent undue pressure being exerted on the wheel, or the slides b may grip the work directly. The cam ring may be rotated by a motor through worm gearing.
