Abstract: 1,264,417. Vertical lathes; vertical turning. MASCHINENFABRIK FRORIEP G.m.b.H. 24 June, 1969 [2 July, 1968], No. 31761/69. Headings B3B and B3T. Operation of a tool change in a vertical turning or boring lathe is initiated through a command from a numerical control of the machine, a slide rest 8 and a ram 9 are brought to a starting position, from which ram 9 is moved on the slide rest 8 so that a tool holder 11 situated in the ram is brought to the same height as a gripper 33 of an empty store station 17 in a tool magazine 14, which is positioned ready to receive the tool. Also, a cover 43 of tool store 16 is turned so that its cutout 44 lies at the position of the empty store station. Slide rest 8 then travels in the direction of magazine 14, so that the tool holder 11 is transferred to the store 16 and thus gripped by a respective gripper 33. The tool holder 11 is then released from the ram 9 and clamp bar 12 is unscrewed from the tool holder. After a time lag adjustable by means of a time relay, ram 9 moves slightly upward to release the cone of the tool holder 11. The store 16 is turned until a desired new tool holder is positioned at the transfer point. Ram 9 moves downward, tool holder 11 is clamped, and slide rest 8, together with ram 9, moves away from magazine 14 to a starting position for the slide rest and ram, from which a new machining operation starts. Cover 43 is turned so that its cutout 44 is remote from the machining position. Store 16 is rotated by an electric motor 18 via a pinion 19, a sleeve 20 and a bush 21 which acts as a clutch. The clutch is adjustable by a control bolt 22 which can be displaced axially by a nut 23 in relation to housing 15. A charge in loading on the bolt is transmitted through a collar at the bottom end of bolt 22, through the inner ring of a radial bearing 24, through a packet of plate springs 25, and through an annular shoulder bearing 26 to sleeve 20, and thus bush 21. A lever 39 acts on store 16 and is attached to a member 40 for a decoding switch 41, the member passing through the hollow central bolt 22, and being rotatably mounted therein. When a chosen tool holder reaches the transfer point a signal is sent through the decoding switch 41 and is used to switch off motor 18. The store is located positively in a chosen position by a locking bolt 28 engaging in a socket 29. An extension 38 on each store station 17 is engageable in a recess 37 in a tool holder to ensure correct angular orientation of the tool holders. Similar means ensures correct positioning of the tool holders in the ram 9. The upper end of the bolt is associated with a safety switch 32 and the bolt is raised by an electromagnet 31. Slide rest 8 is mounted on a vertically adjustable cross-rail 5.

Abstract: 1288756 Projectile fuzes ELLIOTT BROS (LONDON) Ltd 19 Dec 1969 [19 Sept 1968] 44699/68 Heading F3A An explosive charge carried by a missile is detonated in response to an electrical signal obtained by detecting the change in selfcapacitance of the missile body occurring when the missile contacts a target having a comparatively large self-capacitance. A small disc of metal (S) Fig. 4 (not shown), is let into, but electrically insulated from the skin of the missile (B). Across the capacitor C SB  so provided is connected an a.c. generator G in series with a resistor R. The self-capacity of the disc S is represented by the capacitor Cs and that of the missile body by the capacitor C B . Contact with the target effectively introduces a further capacitor C target into the circuit and the resulting increase in current through the load resistor R is suitably detected. In a modification, Fig. 2 (not shown), the standing voltage across the resistor is cancelled out in a summing amplifier by an anti-phase signal from a subsidiary winding of the generator. The magnitude of the anti-phase signal may be automatically controlled to achieve balance, Fig. 3 (not shown).
