Abstract: 1,258,736. Analogue to digital converter. ING. C. OLIVETTI & C. S.p.A. 19 June, 1970 [23 June, 1969], No. 29983/70. Headings G4A and G4H. In an analogue to digital converter the position of a movable member 1 is encoded by means of an error signal representative of the difference between the position of the movable member and the recorded digitized position. The encoder can record its output either in metric or English units. The position of a movable member 1 is indicated by means of a variably coupled transformer having coils 6, 7 and 8. The output of digital to analogue converter 4 fed into coils 6 and 7 indicates the value of the currently recorded position of the movable member, the error signal, being the difference between the actual position of the movable member and the currently recorded position is fed on line 9 to a transformer 10, which has two settings depending on whether the measurement is to be made in inches or metric units. From unit 10 the error signal passes to a control unit 14 which decides first of all whether the error is sufficient to warrant incrementing the counters, and whether the counters should be incremented in a positive or negative direction, and whether or not a fast incrementing of the counter should take place i.e. in hundreds of units-instead of single units. Counter 20 is then incremented by means of clock pulses generated by a timing unit 21 until the error signal is removed. The logic circuitry 17 and 26 controls the carry function of the counter, whether or not the counter adds 1s or 2À54s to itself, whether or not the counter counts in the fast or the slow mode. Counter 20 always indicates the position of the member in metric units. A display counter 27 indicates the position of movable member 1 in inches or metric units depending on the setting of selector switch 13.  The counter unit 20 comprises a series of decades, Fig. 2, fed by means of AND gates 30 to 41. Which AND gates are activated to pass clock pulses CP depends on the signals received by the AND gates. If the counter is to count in units of 2À54 the AND gates receiving signal I are activated, if on the other hand the counter counts in terms of single units the AND gates receiving signal M are activated. The signals F and S control whether or not the counter counts in the fast mode or the slow mode. Signals T1, T2, T4 and T5 determine whether the AND gates are held open for 1, 2, 4 or 5 clock pulses. Signals A, B, C and D generated by carry logic 26 determine when a 1 is to be carried over into the next decade, signal TTR performs the actual carry operation when it is received at the end of a cycle. If a decade changes from a 9 to a 0 the appropriate flip-flop in 42 to 45 is set this generates the A, B, C, D signals, the AND gates 46 to 49 provide a carry function if more than two consecutive units change from 9 to 10.

Abstract: 1,264,360. Making accumulator electrodes, winding and reeling. SOC: DES ACCUMULATEURS FIXES ET DE TRACTION. 19 Dec., 1969 [20 Dec., 1968], No. 62113/69. Headings B3A and B3E. A method of making a coiled accumulator electrode includes stacking electrode and separator strips on an elongate guide 140, engaging one end of the strips with a mandrel 156, rotating the mandrel to coil the strips therearound and varying the position of the guide relative to the mandrel so that the portions of the strips in the guide are maintained substantially tangential to the portions of the strips coiled on the mandrel and so that there is no relative sliding movement between the strips and the guide. The mandrel is split diametrally and one half is withdrawn before the strip ends are offered up to it. A jet of air from a nozzle 160 wraps the end of the strips around the mandrel half, whereupon the other half is advanced to secure the strips. As winding proceeds, the guide 140, which is mounted on rollers 62, is advanced by drive rollers 63, 64 and pivots about a shaft 155 as the diameter of the coil increases. A jack 157 applies a compressive load on the coil. When coiling is completed, the coil is located in a cylindrical cavity formed by a member 158 in position 158<SP>1</SP> and a recess at the end of the guide 140. The member 158 then advances with the guide to a work station, where, after the mandrel has been withdrawn, it is inserted in a metal casing. In an alternative embodiment, the guide; instead of being pivoted, is lowered horizontally as the coil diameter increases so that the uncoiled portion of the strips is always tangential to the coiled portion, Fig. 2 (not shown). The stack of strips is held in the guide either by magnetic or vacuum means.

Abstract: 1,265,475. Change-speed control. SELF CHANGING GEARS Ltd. 27 March, 1969 [29 Dec., 1967], No. 59003/67. Heading F2D. Pneumatically or hydraulically operated ratio-selecting brakes and clutches of a four forward speed and reverse planetary changespeed gear (not shown) on a motor-vehicle are controlled by servomotors (not shown) operated by control valves 11-15 which during a shift interval initially charge the appropriate servo at a high pressure to a point where the differential speed of the brake or clutch mating surfaces commences to fall, the pressure then being regulated to a reduced value to effect a smooth shock-free shift after completion of which the pressure is restored to the high level. As shown, the four forward speed servo control valves 11- 14 are each connected to respective pressure regulating valves 6-9 arranged in parallel between two further control valves 4 and 5 connected via a pressure reducing valve 3 and pressure regulating valve 2 to a reservoir 1, the reverse servo control valve 15 being connected by a regulating valve 10 only to the control valve 4, the control valves 4, 5 and 11-15 being such that each can be conditioned only to connect its ports A or B to its port C, i.e. to pressure or to exhaust for the servo valves 11-15, by electrical control signals conveyed by lines 16-22 under the control of the automatic gear-change control system as described in Specification 802,272, the signals conveyed by the lines 16 and 17 of the control valves 4 and 5 being utilized to modify the pressure level in accordance with accelerator position and governor controlled fuel supply. The pressure to each servo control valve 11-14 is determined by spring loaded means in each of the regulating valves 6-9 which are pressurized from control valve 4, the pressure being augmented via the control valve 5 such that during a shift interval, the control valve 5 is conditioned via line 17 to exhaust its port C via its port A to regulate the pressure of the appropriate servo valve 11-14 to the reduced valve for smooth shift after completion of which the pressure is restored to high level by signal 17 operation of valve 5 to reconnect ports B and C.

The core may protrude through the polyester sheath at only one point in the filament cross-section (as in Fig. 1) in which case the filament is self-crimping in so far as it forms tight helical crimps when relaxed in steam or hot water after being fully drawn. The conjugate filaments may be produced by a process involving the use of the spinneret assembly of British Specification 1,100,430 with the spinneret plate of Fig. 2 in which the protrusions 7 extend upwards from the spinneret plate 4 to the baffle plate of that spinning assembly and serve to restrict the flow to the orifices 5 of the superposed layers of polymer melts confined in the space above the plate 4 in one or more areas adjacent said orifices. Examples relate to the spinning of conjugate eccentric sheath/core filaments in which the sheath is formed from polyethylene terephthalate and the core is formed from a copolymer (80/20) of polyhexamethylene adipamide and polyhexamethylene terephthalamide. Filaments produced according to the invention have the warmth of handle of conventional polyester filaments and some of the dyeability characteristics of polyamide filaments.
