Title: Improvements relating to flame-cutting
IPC: B23K7/10
Filed: 1969-12-12
Abstract: 1,234,930. Flame cutting. TANAKA SEISAKUSHO K.K. 12 Dec., 1969 [13 Dec., 1968], No. 60768/69. Heading B3V. A non-cutting condition during a flame cutting operation is detected by detecting a change in voltage between a torch 2 and the metal 4 being cut. A relay 8 is connected across the workpiece and torch mounted on a movable trolley 12, and is arranged to close when the voltage exceeds 0À8-0À9 volts. During a normal cutting operation the voltage across the workpiece and torch is 1À2-1À8 V. so that the relay 8 is closed and power is supplied through a cable 7 to the motor or clutch of the trolley 12. If a non-cutting condition arises, the volta ge across the workpiece and torch falls to 0-0À5 V<SP>.</SP> to cause the relay 8 to open and the trolley 12 to stop. The cutting oxygen supply is switched off preferably for a predetermined period to allow the workpiece 4 to be heated further so that when the cutting oxygen supply is resumed, the cut is restarted and the voltage is raised causing the trolley 12 to be moved again. If the voltage falls to zero indicating that the flame is no longer contacting the workpiece, both the oxygen and fuel gas supplies are automatically cut off. When the torch moves off the workpiece at the end of the cut, the voltage falls to cause the relay 8 to open and the trolley 12 to stop.

IPC: G06C23/06
Abstract: 730,371. Calculating-apparatus; cash-registers. OLYMPIA WERKE WEST GES., [formerly ORBIO BUROMASCHINENWERKE GES.]. Nov. 3, 1950 [Nov. 4, 1949], No. 26957/50. Class 106 (1). A calculating machine or cash register is provided with alternative and independently operating motor and hand driving means in which the motor operates without stressing a return spring for the hand drive. The main shaft 1 of the machine is adapted to be rocked to and fro alternatively by a motor-driven crank-arm 5 or a hand crank 8, a spring- actuated return lever 6 being engaged when the hand drive is operative. The hand crank 8 is applied to a coupling disc 9 loose on the main shaft 1 which it is adapted to drive in the forward direction (counterclockwise) through the intermediary of a further loose disc 12 connected by a spring 18 to a cam disc 15 fast on the shaft. A crank disc 2 and a link 3 connect the shaft alternatively with the return lever 6 or the motor-driven crank-arm 5, the extremity of the link 3 being fitted with a transversely slidable bolt 27 (Fig. 2) adapted to engage bores in the lever 6 and crank arm 5. Selection of the drive is by means of a rod 19 extending transversely of the machine and provided with appropriately marked finger pieces 20 and 21 by which it can be slid into its two alternative positions. A lever 22 connects the rod 19 with a sliding frame 24 carrying plungers 25 and 26 opposite the bores in the crank arm 5 and lever 6. When, as shown, the rod 19 is in the motordrive position, the plunger 26 enters the bore in the return lever 6 to lock it in home position, and thrust the bolt 27 clear of the return lever and into engagement with the bore in the motor-driven crank arm 5 which is thus coupled to the link 3 for driving the shaft. A notch 31 in the rod 19 releases a bolt 32 to enable the motor-switch to be operated, but the rod holds a bell-crank 35 to maintain a claw 36 in locking engagement with the disc 9 to prevent hand operation. When the rod is moved inwardly to the hand-drive position, the bolt 32 is locked to prevent operation of the motor switch, the bellcrank is released by a notch 33 in the rod to free the hand-driven disc 9, whilst the plunger 25 enters the bore of the crank arm 5 to lock it and thrusts the bolt 27 into the bore of the return lever 6 so coupling it to the main shaft 1. A stop 40 in the disc 9 engages a second claw 37 on the bell-crank to limit the forward stroke of the hand-crank. A second step 39 engages the claw 36 to prevent premature return, a luge 42 on the cam disc 15 engaging an offset 41 of the bell-crank to release the claw 36 from this step at the end of the forward stroke.
