Abstract: 1286802 Tool changers ALFRED HER. BERT Ltd 4 Sept 1969 [9 Sept 1968] 42767/68 Heading B3B [Also in Division B8] Apparatus for identifying articles moving along a path, e.g. cutting tools in a tool magazine, workpieces moving between work stations, or a parcel sorting apparatus, is constructed so that the articles are moved by a chain conveyer, each link of the chain having a block 10 which at a particular station, moves in close proximity to a pneumatic reader 22 to identify the article carried by the link. Each block 10 carries an identifying element in the form of a spool 15 having lands and grooves (Fig. 2, not shown) to form a binary code associated with the article carried. A comparator 29 receives a code of a required article from a tape reader and when the code read by the reader 22 matches the code in the comparator a solenoid hydraulic valve 32 is operated to slow down the drive of the chain and a solenoid air valve 31 is also operated. This valve passes air to a port in the reader 22 which is blocked off by a button 13 on the block 10 at the required slot position. The blocking of the port causes a pressure rise which operates an hydraulic brake valve 34 to arrest the movement of the chain. The code on the spool 15 is read by providing a plurality of slots 23 in the reader which align with a plurality of holes 16 in the block 10. Air is passed down a plurality of passages 24 into the slots 23. According to whether a groove or a land of the spool 15 is opposite a particular hole 16 the air either passes to exhaust via a gallery 17 or pressure builds up to operate pressure switch 28 which passes a signal to the comparator 29. Air is only supplied to the slots 23 when a groove 18 in the block 10 is aligned with passages 26, 27.

Abstract: 1528985 Automatic control of arc welding C MAULE 22 Oct 1975 [25 Oct 1974] 43266/75 Heading G3R A D.C. arc welding circuit includes a frequency converter, isolating circuit and rectifier connected in series between mains supply and output terminals. The converter is driven in accordance with the output current or voltage, and comprises a rectifier bridge, a pair of series controlled diodes and a further controlled diode which operates to turn off the first pair of diodes. The controlled diodes are triggered by pulse amplifiers and transformers driven by a squarewave generator responsive to the output current or voltage. As shown in Fig. 2, a three-phase supply 1a is connected to arc terminals 3a through a rectifier 5, controlled rectifiers 6, 7, an isolating transformer 8, rectifiers 18, 19, inductance 20 and a currentsensing resistor 3b. In operation, the voltage across the resistor 3b is fed through an amplifier (4b), Fig. 3 (not shown), to a squarewave generator (4c) producing a constant duration negative wave portion which causes an amplifier (32) and pulse transformer (33) to turn on the controlled rectifiers 6, 7. At the beginning of the positivegoing wave, another amplifier (34) and transformer (35) turn on a rectifier 13 so that a capacitor 9 applies reverse voltages to the rectifiers 6, 7 and turns them off, followed by the rectifier 13. The duration of the positive wave portion produced by the squarewave generator (4c) varies in accordance with the voltage across the resistor 3b so that the arc current is stabilized. A control voltage proportional to the arc voltage may alternatively be used.
