Title: Improvements in or relating to methods and means for recording on magnetic carriers
IPC: G11B15/29
Filed: 1952-03-18
Abstract: 712,657. Magnetic sound recording and reproducing aparatus. SOUBRIER, M. March 18, 1952. [March 28, 1951], No. 7029/52. Class 40 (2). To facilitate the editing of a magnetic record, one record B, Fig. 1, is driven from a spool 23 to a spool 24 over reproducing, erasing, and recording heads LB, FB, EB while another record is driven from a spool 21 over corresponding heads EA, FA, LA to a spool 22. Any spool may be driven in any direction by bring- ing it, by means of electromagnetic devices 5, 6, 7, 8, Fig. 2, into engagement with a driving drum 39 driven from a reversible motor 33. Each spool is normally held off the drum against a brake by springs 45. The tape or wire records A, B may be brought into engagement with a capstan 41 by rollers 43, 44 controlled by electromagnetic devices 3, 4. In operation, a "rough draft " is recorded on the wire B by operating switches to drive the motor, energise the electromagnetic devices 3, 4, 5, 6, and connect the microphone M to the recording head E.B. Both wires are then rewound quickly by closing the motor-controlling switch 1, disengergising. electromagnetic devices 3, 4, 5, 6 and energising devices 7, 8. The record is then reproduced by closing a switch 13 to the loudspeaker HP. Switches 16, 18 are also closed to simultaneously record on the wire A and erase from the wire B. If it is desired to introduce a passage into the record, the wires are rewound at normal speed and the record is transferred from the wire A onto the wire B. When the required point for insertion is reached the wire B is stopped and wire A moved in the reverse direction. The passage is recorded on the wire A. The remainder of the record is then recorded from the wire B onto the wire A. If during this recording it 'is' decided that part of the record is now useless, the record is recorded onto the wire B again until the useless passage is recorded thereon. The record is then recorded into the wire A, until the exact point for the erasion of the useless passage is reached. The wire B only, is then moved until the passage is erased. The remainder of the record is then transferred into the wire A. If it is desired to detach a passage from the record without erasing it completely,.the head EA is connected with a source of blurring signals 31 by closing a switch 20. The control of the machine may be effected by a selecting lever Fig. 5 (not shown). A simpler method of editing a record which is particularly suitable for office work is described with reference to Fig. 6 (not shown). The invention may be applied to the editing of kinematograph films.

Filed: 1971-10-01
Abstract: 1371630 Lubricating OWENS-ILLINOIS Inc 1 Oct 1971 [2 Oct 1970] 7322/74 Divided out of 1371627 Heading F2A A lubricating device for an endless chain comprises a rotary member engaged with the chain for displacement therewith, a lubricant discharge fitting mounted on the rotary member and having a normal retracted position and a discharge position, fluid pressure actuating means for shifting the fitting from retracted to discharge position, a fluid pressure actuated lubricant supply pump to supply a charge of lubricant to the discharge fitting, two separate pressure fluid supplies for the actuating means and for the pump, and a sequence controlled mechanism to obtain a discharge of lubricant only when the fitting is engaged with the chain. Lubricating device for chain. Figs. 18, 22.- Lubrication mechanism 92 comprises a fourarmed star wheel 580 on shaft 582 having its axis coincident with the centre of curvature of end turn 90, the wheel 580 being driven by chain pins 108 engaging notches 584. One arm 586 of wheel 580 carries a pneumatic motor 588 whose piston-rod 590 carries a lubricant discharge fitting 592. Lines 594 and 598 respectively for air and lubricant are connected from motor 588 and fitting 592 to passages 596 and 600 in shaft 582. Sources of air 632 and lubricant 634 are connected to the passages 596 and 600 in shaft 582 by means of a rotary coupling union 604 and supply systems as shown on Fig. 22, including motor 610 and piston-rod 612 connected to a mounting bracket (614) on which is mounted a three-way valve 618 with a valve actuating member 620 with cam follower roller 624 engaging when in lubricating supply position an operating cam 626 with a short operating section 630 on shaft 582. The orientation of cam 626 is such that roller 624 is operated by cam section 630 only when a link pin 108 is in seated engagement with notch 584 of arm 586. Operation causes, first, air pressure to be supplied to motor 588 causing lubricant discharge fitting 592 into seating engagement with lubricant receiving fitting 112 on that link pin 108 in engagement with arm 586. A charge of lubricant is then supplied to fitting 592, the charge being sumicent to unseat a spring pressed ball valve (664) to supply the charge to fitting 112 and thence through the chain by wick 128 and bores 130 (Fig. 5). Before arm 586 is disengaged from link pin, cam section 630 is passed thereby stopping and retracting the lubricating device. As shown, lubricating will be effected on every sixteenth link pin and chain 40 is therefore formed with a number of link pins exceeding a multiple of sixteen by one so that every pin will be lubricated before any pin is lubricated twice. Specifications 1,371,627, 1,371,628 and 1,371,629 are referred to.
