Title: A method of and means for magnetic tape recording
IPC: G11B15/20
Filed: 1958-11-26
Abstract: 870,825. Digital data-storage apparatus. NYMAN, B. C. G. Nov. 26, 1958 [Nov. 27, 1957; Jan. 31, 1958], No. 38169/58. Class 106 (1). A method of preparing an error-free magnetic tape comprises the measures of recording impulses representative of digital data while the tape is at rest between the steps of a step-bystep feed, recording spacing impulses and where necessary erratum impulses, the tape being then .played back in reverse whereby a copy may be made, the erratum signals disabling the recording mechanism until the next spacing signal is detected. Data recordings are shown at 9-11, 13, 14 and 16 in Fig. 2 with spacing recordings 12 and an erratum recording 15. Fig. 3 shows the error-free copy with blank positions in place of spacing and faulty recordings. A revertive impulse counter is coupled either to the primary recording apparatus or to the copying device. Assuming the former case, depression of a key 32 actuates a set of contacts to send a pulse to appropriate recording-heads 24, to charge a condenser 36, and to energize a driving magnet 31. When the key is released relapse of magnet 31 advances the tape and condenser 36 is discharged to close switch 29. As the tape moves the recorded signal generates an impulse in magnet head 24, which impulse is amplified at 30 and passed to an indicator. If recording fails to take place, the feed-back impulse fails to appear and an alarm circuit is closed or a relay 40 is energized to lock the keyboard.

Abstract: 1396420 Shutter mechanism EASTMAN KODAK CO 17 Aug 1972 [19 Aug 1971] 38380/72 Heading G2A A shutter-actuating member 28 moves downwards to release and open the shutter, the member 28 then being retained in this depressed position, and released to return to its original position by the closing movement of the shutter. In Fig. 1 the mechanism is shown with the shutter closed and tensioned ready for operation. A first shutter blade 14 is prevented from sliding to the right under the action of a spring 22 by a latch 34 which hooks behind a pin 38 on blade 14. In this position the exposure aperture 12 is closed by the shutter. Latch 34 is part of a shutter release member 25, 28, biased upwards by a spring 29. When the release is manually pressed downwards, latch 34 disengages from pin 38, so that shutter blade 14 slides to the right and uncovers the exposure aperture 12 (position of Fig.2). At the same time blade 14 engages and opens a switch S2 forming part of an integrating circuit Fig.4 (not shown) of the RC type including a capacitor (54) and a photo-cell (53) receiving incident light. This energizes for a predetermined time an electromagnet 26 which, in this state, attracts an armature 27 carried by a second shutter blade 16. Thus blade 16 is retained in its original position Figs. 1 and 2 against the action of a spring 24. At the same time the resilient cranked lower end 43 of a leaf-spring 42 secured to the release member 25, 28 latches under a bent-over portion 44 of blade 16. Thus after the release member has been depressed from the Fig.1 position to the Fig.2 position, it is retained in this latter by this latching action. At the same time a switch S 1 forming part of the RC circuit is closed by the release member. When the exposure time as determined by the RC circuit has elapsed, magnet 26 is deenergized and no longer attracts armature 27, so that shutter blade 16 is now free to slide to the right under spring 24, so that aperture 12 is covered again and the exposure terminated, position of Fig.3 (not shown). At the same time the bent-over portion 44 is drawn clear of spring end 43 so that the shutter release 25, 28 returns to its original Fig.1 position. The position of the upper end 30 of the shutter release thus provides a visual indication of the termination of the exposure period.
