    • There is disclosed a veneer lathe comprising a pair of spindles one of which spindles is powered to impart rotating torque to the log and the other of which is non-powered and rotatable with the log, means for detecting the rotation of the non-powered spindle and providing a detect signal, and control means which is operable in response to the detect signal to control the knife carriage feed. The lathe further includes means for detecting the rotation of the powered spindle and providing a detect signal, and means for comparing the detect signals from the two detecting means and providing a control signal, if the difference in angular velocity between the spindles exceeds a predetermined value, thereby to cause the knife carriage to stop its feeding operation.

    • The invention concerns a control apparatus for machines designed to operate on a workpiece. The apparatus comprises a programming element consisting of a disc which has concentric tracks of varying transparency or reflectance; an optical scanner comprising an emitter unit emitting light beams to the programming element and a receptor unit for the light beams which have been transmitted or reflected; drive means for rotating the disc by the relative displacement of a tool and the workpiece; and an electric circuit connected to the receptor unit and to a motor for controlling the speed of rotation of the motor as a function of the intensity of the signal given by the receptor unit. The apparatus is applicable in particular to machines for working on plates, pieces of glass or plastics material, for example window panes, plate glass or lenses.
    • 本发明涉及一种用于在工件上操作的机器的控制装置。 该装置包括由具有不同透明度或反射率的同心轨道的盘组成的编程元件; 光学扫描器,其包括向编程元件发射光束的发射器单元和用于已被透射或反射的光束的接收器单元; 用于通过工具和工件的相对位移来旋转盘的驱动装置; 以及连接到受体单元的电路和用于根据受体单元给出的信号的强度来控制马达的旋转速度的马达。 该装置特别适用于在板上工作的机器,玻璃或塑料材料,例如窗玻璃,平板玻璃或透镜。
