摘要:
A rotary scanning decoder for reading labels having binary data bits each of which comprises a pair of contrasting areas, the ratio of areas in each bit defining the bits'' binary status. The position of the label relative to the decoder is not critical so long as substantially all of the label is seen by the decoder. Means are provided for eliminating ambiguities due to mutilation or foreign material on the label.
摘要:
A calculating machine including at least one numerical data transfer device comprising an input store, a variably positionable output member and a transfer member. The transfer member and input store are relatively displaceable in a first direction and actuating means are provided for simultaneously shifting the transfer member in a second direction. In addition, means are provided for connecting the transfer member to the output member for positioning the latter in response to the shifting of the former.
