Abstract: 1359520 Cartridges EASTMAN KODAK CO 12 Aug 1971 [14 Aug 1970] 37911/71 Heading G2X The take-up chamber of a cartridge is formed so that the trailing end of a film strip being wound into it is prevented from passing completely into the chamber. As shown, a film strip F, originally coiled in the supply chamber (not shown) of a cartridge, is gradually wound across, after frame by frame exposure, into a take-up chamber 5, its leading end being attached to a winding core 13. A tooth 20 in the form of a ramp is located in the passageway 10 through which the film enters chamber 5. The trailing end E of the film has a special perforation 30 which, as it passes over tooth 20, is engaged by the end 22 of the tooth, so that the film is prevented from entering any further into the chamber. Thus the film cannot be wound completely into the take-up chamber, and an end is left protruding by means of which it can be grasped and pulled out without opening the chamber. If the film f has a backing paper strip b, as in Fig. 4, the perforation 30 is provided in both b and f.

Abstract: 867,847. Automatic-exchange systems; magneto amplifiers. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Nov. 13, 1958 [Dec. 6, 1957], No. 38058/57. Classes 40 (4) and 40 (9). Direct current is fed to a load L only when the output windings acw of two magnetic amplifiers 1MA, 2MA are conductive in two separate input circuits. The amplifiers have control windings dcw. The arrangement is used in a control circuit for cross-bar switches. Two rectifiers 1R2, 2R2 connected in series with the local and with 75v alternating current sources S are normally biased back by 150v potential difference across terminals 1P, 2P. A potential of 150v produces by. a voltage double arrangement 1R1, 1R2 or 2R1, 2R2 when the corresponding amplifier 1MA or 2MA is operated is sufficient only to balance the back-bias. When both amplifiers are operated, the 300v from the two voltage doublers is sufficient to overcome the back bias and to feed the load. Matrices of loads, Fig. 2.-A number of loads L11-L44 arranged on a 4Î4 matrix are controlled by two groups of input circuits IUX1- IUX4, IUY1-IUY4. Isolating rectifiers R are connected to the loads. Cross-bar switch control, Figs. 3, 4.-A known arrangement of ten primary switches PS1- PS10 and ten secondary switches SS1-SS10 linking subscriber's lines or junctions l to trunks t is shown in Fig. 3. The hold magnets P1V1-P1V10 to P10V1-P10V10 form a 10 X 10 matrix, Fig. 4, controlled by two groups of ten input circuits IUA1-IUA10 and IUB1-IUB10. Similarly the hold magnets S1V1-S1V10 to S10V1-S10V10 are controlled by input circuits IUC1-IUC10 and IUD1-IUD10. The select magnets are operated before the hold magnets. The select magnets of the primary and secondary switches are arranged in pairs P1H1, S1H1-P10H1, S10H10. The appropriate pair of select magnets is operated automatically by the two input circuits of IUB1-IUB10 and IUC1-IUC10 used to control the hold magnets. These two circuits identify the primary and secondary switches concerned in the connection.

Abstract: 1416425 Radar EMI Ltd 23 Aug 1972 [27 Aug 1971] 40255/71 Heading H4D A movement monitoring system comprises a timer 1 giving a local warning and then a general warning if the timer is not reset either by a manual switch 4 or by a Doppler movement detector 5 which includes a digital counting device. Timer 1 starts from zero time and is reset to zero each time detector 5 senses movement of sufficient magnitude, e.g. 1À5 metres. Thus if, e.g. a crew member is active the timer is continually reset and so local alarm 2 is not activated. If the crew member is stationary for, e.g. more than 2 minutes then the timer energizes local alarm 2. The crew member can then reset the timer either by means of the switch 4 or by making a significant movement sensed by a detector 5 of the type disclosed in Application 40,051/71. If neither of these two actions are taken within, e.g. ¢ to 1 minute, the timer energizes general alarm 3.
