Abstract: 1529675 Variable-speed gear MASSON SCOTT THRISSELL ENG Ltd 22 Oct 1975 [24 Oct 1974] 46134/74 Heading F2D [Also in Division B4]  Driving means for rotary cutters 5a, 6a and draw rollers 3, 4 in a machine for cutting a paper &c. web 1 drawn from a reel 2 into sheets 7, in which provision is made for selecting the length of sheets cut and thereafter preventing deviation from the selected length, comprises a multi-ratio gearbox 12 providing, e.g. twenty-five ratios between shafts 19, 15, and a differential gear 20 with a connection to auxiliary means for effecting ratio adjustments between the stepped ratios of the gearbox and for applying corrections to compensate for slippage of the web in the draw rollers during acceleration or tension variations. The main driving means, consisting of an electric or hydraulic motor 11, is situated either in the shaft 19 between the gearbox and the differential gear or where indicated by chain-dot lines when it drives the other gearbox shaft 15 through pulleys 36 and a belt 37. The cutters 5a, 6a are driven from the shaft 15 through a cyclic drive mechanism 13 which synchronizes the speed of the cutters with that of the web during the actual cutting operation, gearing 16, 17, and a flywheel 14 for reducing the effect of the mechanism 13 on the rest of the apparatus. The differential gear 20 has three connections constituted by the shafts 19, 19a and a belt 24 and pulleys 22, 23 connected to an electric or hydraulic motor 21 or a brake, e.g. an eddy current brake, and forming the auxiliary means. A closed-loop electronic speed control circuit for the motor 21 includes a control unit 29 with inputs from an encoder 18 which delivers one pulse per sheet severed, an encoder 25 which transmits a D.C. voltage proportional to the speed of the shaft 19, an encoder 9 which generates a predetermined number of pulses for each revolution of a wheel 8 in contact with the web, and a sheet-length setting unit 28. To facilitate setting up the machine without feeding web material, a switch 35 when actuated by lifting of the roller 4 clear of the web connects the unit 29 with an encoder 30 driven from the shaft 19a instead of with the encoder 9. The differential gear may alternatively be placed in the drive to the cutters.

Title: Arrhythia detecting method and apparatus

Filed: 1972-10-11
Abstract: 1398429 Electromedical apparatus  F HOFFMANN-LA ROCHE & CO A G 11 Oct 1972 [3 Nov 1971] 46836/72 Heading GIN An absolute derivative signal derived from a patient's heartbeat is monitored by transforming an incoming signal into a first integral signal 32 representative of the average magnitude of the incoming signal over a plurality of heartbeats, and simultaneously into a second integral signal 31 representative of the magnitude of the incoming signal over a single heartbeat, and comparing the levels of the two signals to generate an output signal when the level of the second signal attains a predetermined relationship with respect to the level of the first signal.  As shown, an e.c.g. signal detected by electrodes 11 are applied to an input circuit including a preamplifier 13, an AGC unit 14 and a differentiating circuit 15 to provide the signal shown at (a) in Fig. 4. This differentiated signal is applied to a processing unit which includes a voltage follower (23), a narrow bandpass filter (24), a rectifier (25) and an amplifier(27) Fig. 2 (not shown). The filtered, absolute derivative signal shown in Fig. 4b is then simultaneously applied via respective diodes, to a pair of integrators 31, 32 which provide the integral signals 31', 32' shown in Fig. 4 c. It is seen that integrator 31' has fast attack and release times thereby providing sharp peaks corresponding to the QRS portions of the e.c.g. signal, whereas integrator 32 has long attack and release times thereby making the level of the integral signal 32 dependent upon prior heart beat signals. A comparator 38 compares the two integral signals to provide an output via a NAND gate 21 and a one-shot device 46 when the level of signal 31 attains the level of signal 32'. As shown, a noise detector 17, including an integrator, is provided, its output being compared with the integral signal 32' in a comparator 19. - Upon detection of a noise spike which exceeds the level of signal 32', the NAND gate is inhibited and a discharge device 18 is operated to prevent the integrator 32 being affected by the noise spike.

Abstract: 1,235,955. Change-speed gear. FORD MOTOR CO. Ltd. 25 Sept., 1969 [4 Nov., 1968], No. 47220/69. Heading F2D. Direct drive, three reduced ratios and one reverse are provided by three identical sun-ring trains, the first two, 14, 16, forming a Simpson gearset, the third, 18, providing a torque-split output drive. On a motor vehicle the final drive ratio is so chosen that direct drive forms what is normally an overdrive. In all forward ratios a clutch 42 drives the first ring-gear 20 from the turbine T of an inputdriven torque-converter, In one-way split torque first ratio, only the clutch 42 is engaged, and reaction for common suns 22 of the front two trains, is taken by the carrier 30 of the second train by a one-way detent 56. The ring 28 of the second train drives the sun 36 of the third, the ring 34 of which reacts on a one-way detent 62 to provide a reduction drive to the output carrier 38, which combined with the torque applied to the first carrier 24 to provide a split torque output 12. Upshift to one-way split-torque second is by additionally engaging a clutch 58 to lock up the third train 18. Upshift to two-way, single-torque path third is by additionally applying a brake 48 to the common suns 22, so that the front train drives alone. Upshift to two-way, split torque, direct-drive fourth is by engaging, in addition to the two clutches 42, 58, a second input clutch 50, driving the common suns 22, and releasing the brake 48. For reverse, the clutch 50 is engaged, with brakes 54, 60 bridging the one-way detents 56, 62, these brakes also being used for two-way drive in first and second ratios.  All the clutches and brakes are fluid-pressure operated, and numerical ratios are specified in Fig. 2 (not shown).
