Title: Digital timing circuit for display sequencing in two-digit wristwatch
IPC: G04G9/00
Filed: 1975-08-28
Abstract: 1486882 Electronic watches HUGHES AIRCRAFT CO 28 Aug 1975 [13 Sept 1974] 35589/75 Heading G3T An electronic timepiece, e.g. a ladies watch having an electro-optical display with only two digits which are activated to display hours then minutes alternatively, is provided with a timing circuit, Fig. 2, which after activation by a push switch 26 first causes the display of hours for ¢ sec, then a blank display for ¢ sec, then a minutes display for ¢ sec and finally a blank display, the timing circuit being reset until the next time the demand push-switch is depressed. In Fig. 2, with push-switch 26 open, a NOR gate 66 blocks 4 Hz negative clockpulses derived from a frequency divider 14. If switch 26 is momentarily closed a "1" input is applied to gate 66, and this is maintained by a latching means including NOR gates 60, 62 and an AND gate 64 when the switch is released. The resultant positive 4 Hz clockpulse train from gate 66 is converted to a two phase clock source by transmission gate 68 and inverter 70 and clocks a binary divider counter chain of toggle flip-flops 72, 74, 76, 78. Selected outputs of the chain are applied to a NOR gate 80 and AND gate 82 to produce display sequence command signals DO and DH as illustrated, Fig. 3 (not shown). When signal DO is at logic "0" level the display will be blank; when DO and DH are both at logic "1" the hours will be displayed and when DO is at logic "1" and DH is at logic "0" the minutes will be displayed. Finally when the inputs from the flip-flop chain to a NOR gate 84 are all at logic "0" its output will set flip-flop 76 and gates 60, 62 will change output levels. After a 4 Hz pulse makes Qi of flip-flop 72 go high, the output of gate 84 goes low and the timing circuit is in its original state waiting for the next display demand by switch 26. The timepiece circuit, as illustrated in Fig. 1 is the subject matter of Specification 1482176. Briefly, the time counters are coupled via transmission gates 30, 32, 34, 36 to a decoder 38. A multi-plex driver 28 responds to the timer signals DO and DH to switch the respective transmission gates so as to send hours or minutes information to the decoder 38. The decoder emits seven signals to a driver 48 for transmission to appropriate display segments. Multi-plex driver 28 also controls a digit driver 49 which causes tens of hours or tens of minutes to be displayed on an LED display device 52 and units of hours or mins to be displayed on LED device 50.

Abstract: 1318095 Digital recording on magnetic thin films SPERRY RAND CORP 29 July 1970 [30 July 1969] 36680/70 Heading G5R Binary digits are recorded on tape 60 having a uniaxially anisotropic magnetic film which is too thin to support block walls, in the form of domains 70 of magnetization parallel or antiparallel to the easy axis 66 of magnetization, separated by NÚel walls 72 (in which the direction of magnetization rotates in the plane of the film) in which the direction of magnetization rotates in the same sense (clockwise as shown). The necessary magnetic head, Fig. 4, has a conducting strip 20 and two uniaxially anisotropic magnetic layers 16, 24 in which the easy axes 62, 64 are inclined to each other and to the tape 60. The magnetizing field H R , (Fig. 3b) is suitably oriented by changing the driving current I, (Fig. 3e) in the strip 20. To record digit "O" current value 58 is used to produce a field HR at 90a which has components both transverse, H T  Fig. 3c, and longitudinal H L  Fig. 3d, with respect to easy axis 66. H T  is greater than the anisotropy field HK of the tape, while H L  is less than the coercive force He. The resultant magnetization M at 92a, Fig. 3a, is then aligned with easy axis 66. To then record a digit "1"' current I is momentarily increased at 94 before being reversed at 104. The direction of magnetization of the head layers 16, 24, is then such 96, 98 as to produce zero field H L  and increased field H T . The tape magnetization M in the wall 72b is thereby rotated through the transverse position in clockwise sense. A similar procedure is used to separate digits "1" and "0" to produce a wall 72e with magnetization in the same sense. The magnetic tape film may be a Ni-Co-Fe alloy, 200 thick. The head 10 consists of the conductive layer 20 between alternate magnetizable layers (12), 16, 24, (28) and insulative layers (14), (18), (22), (26), Fig. 1 (not shown), and is preferably formed by vapour deposition.

A cloth web to be cut transversely at equally placed marked points is fed to the cutting shears by two pairs of feed rollers 3 (only one shown), Figs. 3 and 5. The lower rollers 3 comprise discs staggered in feed direction and protruding through slots 4 in a table top 2, and the upper rollers 5 are mounted on pivoted arms 7 and urged against the rollers 3 by springs 12. The rollers are driven by chain drives 24, 45 from an electric motor, and a clutch 22 is provided in the drive. Associated with one of the drive sprockets 27 through a second clutch is a control disc 29 with a cam lobe 33 co-operating with a switch 35 angularly pre-set for length of feed. When the required length has been fed, the switch is actuated to break the motor circuit and apply a brake to the drive. The web can then be fed manually, to obtain accurate register, by a hand wheel associated with a switch to release the brake. The web feed can be switched on by a manual switch or by a switch 61, Fig. 8, actuated when a wire stump 66 on the shears 60 engages a hinged plate 58. Alternatively, the shears may carry an opaque disc which interrupts a light beam to a photocell so as to start the feed. When the switch 35 is opened, it also releases the clutch for the disc 29, which is restored to its original position by a spring 32. A counting device may prevent switching on of the feed when a given number of web sections has been cut.

May 5, 1931, No. 13223. Convention date, May 5, 1930. [Class 44.] In a latch particularly for vehicle doors, a single spring member acts on the bolt to shoot it and on a movable member operating to retain the outside handle in predetermined position irrespective of the extent to which the bolt is shot. A lever 13 pivoted at 12 has an offset end 14 interposed between the follower 7 operated by an outside handle 9 and a projection 6 on the bolt 5. A spring 10 mounted at 11 on the bolt has sliding engagement at its outer end with a grooved projection 15 on lever 13. The spring serves to shoot the bolt and at the same time causes the portion 14 of lever 13 to hold the follower 7 in abutment against the endplate 2 of the latch casing, so that the handle 9 does not sag should the bolt be incompletely shot. A sliding piece 37 is adapted to be moved downwards so that its upper end engages behind the upper end of lever 13 to prevent operation of the follower. A bridge-piece 36 secured to the casing guides the bolt and limits its movement by co-operation with recesses 34 and has upstanding lugs which guide member 37. A modification is described in which the spring is mounted on the lever 13 and its free end bears against a shoulder on the bolt.

Abstract: 344,448. Thermionic valves. STANDARD TELEPHONES & CABLES, Ltd., Columbia House, Aldwych, London.- (Clavier, A. G. ; 46, Avenue de Breteuil, Paris.) Dec. 3, 1929, No. 36941. [Classes 39 (i) and 40 (v).] In a valve for generating o s c i I - lations of very high frequency the interaction of two or more streams of electrons sets up oscillations in a conductor such as the anode, the oscillatory circuit not including any part of the space discharge path. The electron streams may be produced by filaments or indirectly heated cathodes ; or a single cathode may be used, the second stream of electrons being obtained by reflection. As shown in Fig. 1, two flat cathodes 1, 1<1> heated by separate heating elements, are arranged one on each side of an anode 2 of grid formation. It is suggested that electrons from either cathode pass through the anode, and, falling into the retarding field of the space charge near the other cathode, are reflected back through the anode ; the oscillation of electrons sets up oscillations directly in the anode which may be radiated from the anode or by means of conducting rods 9, 10, connected with the anode, and mounted inside or outside the envelope. In the arrangement shown in Fig. 3, in which two filament cathodes 1, 1<1> are arranged one on each side of an anode 2, plates 3, 3<1>, connected with the filaments or maintained at a slight positive or negative potential, are provided for preventing the formation of negative charges on the envelopes, and control electrodes 4, 41 are mounted between the anode and cathodes and are maintained for example at a positive potential so as to accelerate the electrons. In another valve, Fig. 5, a single cathode 1 is mounted inside a helical anode 2 connected with radiating rods 9, 10 and an outer electrode 3 is maintained at a potential such that electrons from the cathode are reflected or repelled, the electrode 3 thus acting as a virtual source of electrons ; or the electrode 3 may be arranged so that parts of it emit electrons and other parts act as a screen to reflect or repel electrons. In a modification of this arrangement shown in Fig. 6 in which the cathode is not shown, an auxiliary helical electrode 21 is connected with other valves for modulation or amplification purposes ; or the auxiliary electrode 2<1> may be omitted and a source of alternating or modulating potential applied directly to the anode at two points. Several units in series or parallel may be mounted in a single envelope and connected with a single radiating system.
