摘要:
A numerical control unit and associated method are provided for controlling a machine tool having linear and rotating axes. The control unit is adapted to machine the workpiece at an instructed feedrate, whereby it is first determined whether the machining mode is in a purely linear interpolation mode (G1). The control unit is also adapted to determine, if in the linear interpolation mode, whether a move command is for the rotating axis alone, this being the case, determining a new radial distance between the tool starting position and the center of the rotating axis. With these determinations, the instructed feedrate is corrected to become a feedrate equal to the actual relative speed of the tool with respect to the workpiece.

A system is provided for improving frame adjustments of automatic embroidery machines. Groupings of holes are punched in an elongated tape (46) corresponding to binary numbers. The tape (46) is read by an electro-optical reader (20) which converts the information on the tape to electrical pulses which, in turn, control a drive system for causing the embroidery frame to move predetermined discreet distances.

A bar-code label has a combination of a plurality of narrower slots and a plurality of wider slots encoded to represent specific binary data containing information and/or instructions. The slotted bar-code is encoded on a rigid label member, such as a metal sheet. A bar-code encoding device used to encode the slotted bar-code has a pair of punches, one of which is adapted to form the narrower slots and the other of which is adapted to form the wider slots. Both of the punches are operated simultaneously whenever one of the narrower orwider slots is formed. The blank label is fed past one of the punches to form all of the narrower or wider slots before forming the rest of the wider or narrower slots with the other punch. The encoded label thus formed is suitable for use in painting or coating processes which would obscure a conventionally printed bar-code label.

A chemical dispensing system features a card reader in data communication with a controller to programmably control the transfer of chemicals between a supply of chemicals (fig. 1, #18) and a washing chamber (fig. 1, #14) while allowing retention of a permanent record of the programmed status of the controller.

The invention relates to a programme unit for the programmed control of a device for adjusting the value of a physical quantity, said programme corresponding to a preselected variation of said quantity for a preselected time interval, which in accordance with the invention is characterized by a punched card reading unit for reading a punched card having a programme encoded therein in the form of a configuration of punched holes in preselected positions of an array.
