Title: Numerically controlled nibbler workpiece positioning device - has feed rate and steps computed to avoid any double machining
Inventor: KOERKEL RAINER
IPC: B23D33/02
Filed: 1975-03-21
Abstract: The method for positioning workpieces for nibbling on a numerically controlled machine tool is distinguished by multiplying the path increments of the faster axis by a selected factor and adding them together per nibbling step. This sum is compared with the remainder of the path. If the sum is the same or greater than the remaining path, a check is made if the last nibbling step is the first of a path. The remaining path length is divided into equal path segments which are used as nominal values for the width of nibbling steps. This avoids a last nibbling step with too little material.

Title: Dialling pulse normalising circuit - integrated by mos technique and produces preset pulse length by flip flop and NAND-gate
Inventor: HUCKFIELD ANTHONY CHARLES
IPC: H03K3/356
Filed: 1976-06-10
Abstract: A normal lifting circuit, integrated by using the CMOS technique, is used to generate and store dial pulses in telephone sets and to produce a pulse of predetermined duration when the voltage reaches its normal value. The timing signal input is applied to a delay unit, consisting of a p-channel transistor (M31) and a capacitor (C31). A NAND-gate precedes input (B) and receives on one input the timing pulse and on the other the same delayed pulse as the input (A) of the RS flip-flop. The output (Q) of the latter is passed to a gate consisting of a transmission gate (TG) and an inverter (J). The inverter also receives the timing pulses, together with one control input of the gate (TG). The delay unit prevents the resetting of the flip-flop. The gate (TG) produces a logic '1' until the timing pulse, produced after the voltage has been switched on, has ended. The NAND-gate resets the flip-flop.
