Title: Automatic shut-off system for magnetic tape reproducers and recorders
IPC: G11B15/46
Filed: 1973-06-09
Abstract: 1439653 Tape recorders; auto-stop devices TECHNICAL Inc 9 June 1973 27572/73 Heading G5R An auto-stop device for a tape recorder includes a capstan-driven shaft 3 which contacts pressure roller 1, the stopping of the tape 21 and hence of the roller 1 at the reel end causing displacement of the still rotating shaft 3 around the periphery of the roller 1 to unlock a start key 19 and switch off the recorder. The shaft 3 is mounted on a bracket 9 which is pivoted on a shaft 6 of a plate 8, and is biased against the pressure roller 1 by a spring 11 acting on the plate 8, which is itself capable of limited pivotal movement. The shaft 3 is driven from the capstan 2, and at the same speed thereas, by gears 5, 7, 4 of equal diameter, so that while the roller 1 and the shaft 3 are both driven there is no relative movement therebetween; but when the roller 1 is stopped the shaft 3 is driven round the periphery of the roller 1, pivoting the bracket 9 against spring force 12 so that a projection 9<SP>1</SP> thereon engages a pin 13 of a lever 17 pivoted on a locking bar 18, moving the free end of the lever into the path of a cam 16 on capstan flywheel 20. The lever is thus moved longitudinally by the cam 16 to shift the locking bar 18 and release the key 19. The device is particularly applicable to cassette machines.

[Also in Group XXII] An atomizer, comprises concentric tubes 45, 46, 47, and heating fluid, e.g. steam, is admitted at 18 and passes along an annular chamber 51 and is exhausted at 20. Compressed air is admitted at 28 and is heated as it flows through an annular chamber 56 to radial channels 79 leading to a chamber 68. A wire helix 80 welded to the tube 46 improves heat transfer. From the chamber 68 the air flows through the tube 45 carrying with it liquid, e.g. oil particles, which are formed when the oil, fed at 22, leaves a nozzle 70 and strikes the end of a core member 81. The latter is held in position by radial arms 82, 83. The resultant oil mist flows from an outlet 33 to a number of open-ended pipes which direct it against the upper and lower surfaces of sheet metal during its rolling process (see Group XXII). Means are provided for varying the supply of oil to the atomizer in accordance with the roller speed.
