Title: Improvements relating to the laying of underground piping, especially water mains
IPC: E02F5/10
Filed: 1962-07-27
Abstract: 976,421. Laying pipes. E. A. YATES, J. E. YATES, and A. C. YATES. Oct. 25, 1963 [July 27, 1962], No. 28852/62. Heading F2P.

Patent GB-858766-A (GB)
Title: Storing data signals on tapes
IPC: G11B27/10
Filed: 1957-09-13
Abstract: 858,766. Magnetic tape recorders. DIRKS, G. Aug. 7, 1958 [Sept. 13, 1957], No. 28879/57. Class 40 (2). [Also in Group XIX] Information is recorded on and read from magnetic tape using tracks at an angle to the direction of motion of the tape, the tape being moved intermittently and scanned while stationary by a transducer traversed along one or more such tracks. Fig. 1 shows cam-operated means for moving the tape 1 and pick-up head 31; a shaft 17 rotates continuously and contoured cams 15 and 16 and pivoted arms 7 and 8 cause a tooth 2 to engage a hole 4 and advance the tape intermittently, except when an electromagnet 22 is energized to hold arm 8 down. A cam 38 reciprocates a bar 30 carrying pick-up head 31 except when electromagnet 37 is energized, and a pick-up head 34 examines recorded control marks 33 to identify a desired track 29 and stop the tape movement while the track is read, transferred to a magnetic drum 40 and checked for transfer errors. Energization of electromagnets 22 and 37 and transfer of information from tape to drum is controlled by the arrangement of Fig. 2; 22 is normally de-energized to allow step-by-step tape movement, but a signal from read amplifier 48 (which may result from simple scanning of marks 33 or from counting them) causes the gas-filled trigger tube 42 to conduct to energize 22 and stop the tape, and also triggers tube 44 having in its anode circuit a relay 47 which opens contacts 67 and 68. Capacitor 69 ensures that 68 are held open until contacts 25a also open (they open once every revolution of shaft 17, see Fig. 1) and 37 is thus de-energized to allow scanning of the desired track by head 31. Information transfer is via two triggered gates 49, 50; 49 is opened by the signal from 48, and 50 opened by a signal from a mark 70 through read head 72 and closed by a mark 71 after the information has been written by head 41 on the drum. The written information is checked at 51 for self-consistency and if correct the " 71 " pulse is passed on line 75 to close gate 49 and fire tubes 43 and 45, hence energizing 37 and de-energizing 22 by action similar to that already described for pulses from 48. If the check shows the transferred information incorrect 51 gives no output and 31 re-scans the track and re-records the information on the drum (by over-recording, or an erase head may be used) until it is correct. In a modification (Fig. 3, not shown), the tape is driven by a sprocket-wheel which is stopped by control marks similar to 33, the head 34 being located in advance of 31 because of the inertia of the sprocket and motor. Instead of using marks 33 for identification of tracks 29, a photo-cell may be used to count the sprocket holes 4. The tracks 29 may be disposed at an angle other than 90 degrees to the tape travel, to increase their length. Specification 820,115 also is referred to.
