Abstract: 876,847. Driving magnetic tapes. EPSYLON RESEARCH & DEVELOPMENT CO. Ltd. Oct. 20, 1958 [Nov. 15, 1957], No. 35714/57. Class 40 (2). A capstan 1 has a pinch-roller 2 pressed against it to feed the tape and they are slightly separated to allow free passage of the tape but at all times, both rollers are geared to rotate together by gears 8, 9. Due to the gear-tooth form, roller 2 will have a small phase lag on capstan 1 when separated from it compared with when in the drive position, so that the action of engaging the tape drive will require acceleration by the roller 2 to remove this lag. To avoid the consequent delay in the initiation of tape drive at playing speed, the gear 9 is driven from the capstan 1 by frictional means 10, adjusted by the locking rings 11. Slipping occurs on drive engagement, obviating the acceleration. The members 9, 10 may be combined in one member of, e.g. PTFE, while the gear 8 and the arrangement 9, 10, 11 may be interchanged on the capstan 1 and the roller 2. Specification 845,297 is referred to.

Abstract: 1360504 Labelling machine CEIKO CEIKI CO Ltd 3 Aug 1971 [14 Aug 1970 6 Nov 1970 29 Dec 1970] 36462/71 Heading B8F [Also in Division B6] A labelling machine in which labels on a carrier tape are fed from a spool 58, being printed by means 42 when in position 44 prior to dis charge through opening 49; inking rolls 34 being moved across the means 42 as this means moves toward the label. The carrier tape is passed back over member 60 and received on spool 25. An electric motor is mounted in hand grip 1 and movement of lever 2 allows one revolution of disc 11, one half revolution when the lever is pulled in, and one half revolution when it is released, causing lever 19 which is rotatably mounted on it at 20 to move first to the left, then to return to its original position. Printing means 42 are carried on a means 45, which is fixed to lever 19, and they contact the label 44 when lever 19 moves to the left. In this movement a projection on means 45 engages arm 36 carrying ink rolls 34, swinging them in the direction into the drawing over the printing surfaces. Lever 19 engages projection 30 on a lever 27 and rotates lever 27 on moving to the left; when 19 returns a ratchet clutch engages lever 27 with the spool 25 to feed the carrier tape and advance the printed label to space 49. As member 45 is pulled back by lever 19, a label pushing-out and applying member 46, sliding on the top edge of the casing 26, is pulled to the right against the tension of spring 51 by the engagement of rod 55 with a step 54. Just before member 45 is fully withdrawn rod 55 is released from step 54 by projection 57 and member 46 is forced suddenly to the left by spring 51 to eject the label from window 49. More than one row of printing surfaces 42 can be used, each served by a different colour ink roll 34 if necessary. In other embodiments of the invention a member may be provided adjacent the opening 49 to allow the discharge of a label only when it is pressed against an article, or mechanical means may replace the electric motor.

Title: Improvements in and relating to navigation systems for marine and like craft and apparatus therefor
Inventor: LUSKIN BERNARD
IPC: G01S1/02
Filed: 1961-10-12
Abstract: 966,197. Electric records; navigation. LITTON INDUSTRIES Inc. Oct. 12, 1961, No. 36613/61. Heading G5R. [Also in Division H4] Errors in a dead-reckoning navigational system (e.g. a system using inertial techniques)which traces the apparent track of a navigable craft on a contour (depth profile) chart are eliminated by measuring the actual depths at selected instants and then manually adjusting the dead-reckoning system by shifting the traced track parallel to itself until the apparent depth indicated by the trace coincides with the actual depth measured at any particular instant. In the described embodiment the contour chart 32 (Figs. 2 and 3) is formed as an electrically insulating base 31 carrying electrically conductive segments 32 separated by depth contour lines 33 of insulating material and, as shown in Fig. 2, the various segments 32 are biased to respective potentials corresponding to the depths represented thereby so that in operation, an electrically conducting stylus 26 (see also Fig. 4) which is driven across the chart (the apparent track) under the control of the dead-reckoning apparatus (not shown) results via a servo balancing arrangement 42, 43, 44 in the production of a rotation of a shaft 45 in a direction and by an amount proportional to the variations in depth along the track traced by the stylus. For measurement of the actual depth a known form of echo sounder comprising a transducer 19 driven by an acoustic pulse transmitter 18 under the control of a keyer 49a is employed. This operates in known manner in response to echoes from the ocean bed 20 to supply a signal via a "print" amplifier 17 to a recording stylus 15 which traverses the width of a chart 13 at a high speed the chart being calibrated (across its width) in units of depth and driven in the direction of the arrow at a speed related to the speed of the craft by means of motor 14 which also controls keyer 49a. The actual depths are thus recorded as a trace such as 22 and to correlate the latter with the apparent depths as tracedby stylus 26 on chart 30 the rotation of shaft 45 is arranged, by means of a conducting ring electrode 46 rotating with shaft 45 and provided with an insulating portion 47 which cooperates with a brush electrode 48 driven by a scale repeater 49 via motor 14, to trigger a pulse generator 50 which supplies its output to stylus 15 via "print" amplifier 17 at instants determined by the rotary phase displacement of the circulating portion 47 with respect to the rotating brush 48. A trace such as 24 is thus produced on chart 13 which coincides with the trace 22 only if the deadreckoning apparatus is without error. When error is present the latter apparatus is corrected by adjustment of the co-ordinate drives of stylus 26 by means of controls 51, 52 (Figs. 2 and 4) until the two traces coincide. U.S.A. Specification 1, 785, 241 is referred to.
