The speed of a steam turbine 2, e. g. driving an alternator, is retroactively controlled by a fast acting analogue loop and a parallel, slow acting, digital loop. Pulse signals from three detectors 3, 4, 5 are compared at 9 and warning given if in disagreement; digital pulses obtained by a comparison of pairs are supplied to a digital/analogue converter 10 for comparison at 11 with a reference 12, and to a device 13 where comparison is made in digital form, the result being converted to analogue and added at 15 to the amplified output of 11. The composite signal is limited if necessary at 16 by any of a variety of values such as steam pressure and is further combine at 17 with a signal derived from the power output of the alternator. The control signal is then passed through a non-linear network 19 which compensates for non-linearity in the electro-hydraulic control 20 of the steam valve. If the turbine has a re-heat stage this is also controlled by similar devices 21-23, 24 being a closing signal used during starting.

Abstract: 1323339 Audible signal detectors TEXAS INSTRUMENTS Inc 8 Sept 1970 [11 Sept 1969] 42926/70 Heading G4F [Also in Divisions H1 and H3] An acoustic wave, for example of the Rayleigh surface wave type, is detected by metal-oxidesemi-conductor field effect transistors due to piezo-resistance changes induced by the wave. The converter, 34, causes a Rayleigh wave to propagate along the surface of the N-type silicon substrate 22. The wave causes a piezoresistance effect on the inversion layer between the source 24 and drain 26, of a field-effect transistor. The gate electrode, 30, of the transistor is biased to form an inversion layer beneath the oxide layer 28 and the piezo-resistance effect causes current changes in the output circuit 20, 44, 46. The system may function as a delay line by spacing the converter 34 from the transistor. By arranging the transistors in patterns, filtering and decoding may be effected.

Title: Improvements in data transmission systems
IPC: G06V10/30
Filed: 1964-10-22
Abstract: 1,073,349. Digital calculators. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 22, 1964 [Nov. 8, 1963], No. 4304O/64. Heading G4A. [Also in Divisions G1 and H4] A data transmission system in which received signals are subject to distortion comprises an arrangement for sampling a received signal on a time sequential basis, calculating arrangements for multiplying individual samples with separate discrete values of an analysis function and a summing arrangement for combining these products to obtain an output representing the transmitted signal from which the received signal was obtained. The invention applies particularly to the transmission of digital data over telegraph lines, where considerable distortion of the digital signals may occur. Digital data #(t) (Fig. 1) after transmission over the line L appears as the distorted waveform h(t). This is fed to a delay line #, and the signals appearing from each delay element 8 of the line are multiplied in the units 1-8 with an analysis function s(t) which is predetermined to relate to a function which can be reliably interpreted and which is generated in the unit 9. The outputs from the multiplying units are added together in a'unit 10, whose output is the cross correlation function # representing the delay times. This function reliably indicates the signal input #(t) to the system. A suitable analysis function s(t) is derived as follows. If g(t) is a function determined in advance which defines the form of pulse required at the correlator output each time that #(t) (representing a single pulse) is sent on the line,theng(t)=s(t).h(t), or in terms of frequency S(W) = G(W)/HW. The Fourier components in the spectrum H(W) are obtained by developing samples from h(t) by means of tappings on a delay line (#, Fig. 3) and connecting the tappings through amplifiers (A) to grouped resistors (R m ) connected to current adders (R s ). From these adders Fourier coefficients are produced of the function H(W). The Fourier coefficients of a required function G(W) are stored in a legister (11), and the quotient G(W) is determined in a unit (12). The Fourier coefficients derived therefrom and representing S(W) are passed to a synthesizer (13), which operates in the reverse manner to the analyser described above to deliver the required function s(t) in sample form. This is recorded in a store (14). The Fourier analysis and synthesis system is then disconnected, the store is connected to the amplifiers (A) via switches (S 1 -S n ) and the delay line can then be used in producing the correlation output for any signal #(t) applied to the system.

Abstract: 1403138 Film transport AGFA-GEVAERT AG 13 Sept 1973 [13 Sept 1972] 43108/73 Heading G2A A feeler 9 is urged into engagement with a metering perforation 2a in a film-strip 2 by a spring-urged first control member 16 and drawn to a first end position by a spring-urged second control member 20, and as the feeler is drawn to a second end position by the film during transport it causes the transport mechanism to be locked, the feeler then being disengaged from the perforation and drawn back to the first end position by the second control member. Fig. 1 shows the mechanism during film transport, the slider 3 moving to the right to effect this operation and to tension the shutter. A rack portion 3b of slider 3 drives a differential mechanism consisting of an input 6 and two outputs 4, 15. When a spring-urged locking lever 11 is engaged with the teeth of output 15, all the torque from input 6 is applied to output 4, which drives the film take-up spool 5. The tooth 9b of the slidable feeler member 9 rides over the film until it falls into a perforation 2a, the feeler being urged downwards by a spring 8, and also by engagement of a notch 16b of control member 16, urged anti-clockwise by a spring 18, with a lug 9c of feeler 9. As the tooth 9b is carried in direction 10 by the film, lug 9c moves clear of notch 16b, so allowing member 16 to be pivoted further anticlockwise by spring 18, into the position of Fig. 2 (not shown). It now bears against one end of lever 11, pivoting it clockwise out of locking engagement with output gear 15. This terminates film transport, since the output gear 15 is now free to move, and receives the torque from input 6, since the frictional retardation due to the film holds output 4 against rotation. (As the slider 3 moves to the right during its transport movement, it also pivots a lever 22 clockwise, a linked lever having a pawl arm 28 which hooks behind a drive lug 30a of a flash-cube socket 30 and rotates it anti-clockwise). As the next film transport movement begins, a sloping edge 9d of feeler 9 rides up a fixed pin 1e and is thus lifted out of the perforation. The second control member 20, pivotable on the same pin 1 a on which feeler 9 slides, is biased by a spring 21. As feeler 9 lifts clear of the perforation, it is  engaged by member 20 and urged towards a stop 1b Fig. 4 (not shown). The shutter release is actuated in the position of Fig. 2 (not shown), in which the film has been transported and the shutter tensioned. This also releases mechanism which engages and pivots member 16 clockwise, so that it disengages from lever 11. This is now free to be urged by its spring 13 back into locking engagement with output gear 15, so that the output 4 is now able to effect further film transport.

The rod carries a disc 37 for mounting other test pieces 14 and means 16 are provided for urging the rod 34 towards the spindle 1 to press the test pieces together, the disc being mounted on the rod by a self aligning joint 36, and means 42 connecting the disc and hollow shaft to permit axial movement between them and transmission of friction torque. As described, the rod 34 is advanced by a piston 22 in a cylinder bearing against a rod 24 which engages the rod 34 through a ball joint 35. The disc 37 has apertures for collets 44 at various radii, Figs 2, 8, the collets and specimens 14 being locked in position by rods 45 which are radially adjustable by handwheels 43. Cooling water ducts K, K, are provided. An annulus 38 is secured by a rigid 41 or resilient 39, 40 connection, according to whether as in the latter case, it is desired to even out oscillatory variations in friction load, to the disc 37 and is connected by leaf-spring or cable connections 42 see also Figs. 4-7 (not shown) to a flange 27 on the shaft 25 so as to allow relative axial movement. An arm secured to the shaft 25 transmits force to a torque measuring device 15 as described later. In operation, the rod 34 is urged to force the specimens 14 against the specimen 11 being rotated by the shaft 5. Friction torque is transmitted by the disc 37, shaft 25 and arm 28 to the device 15. The shaft 1 drives another shaft 7 through a worm, the shaft 7 having a tachometer 8 at one end and a crank 9 at the other, the latter being used for tests involving oscillation between specimens as described below. The apparatus may also be used for testing annular specimens and "shaft and sleeve" test pieces. For the latter, a housing 52, Fig. 13 is attached to the disc 37 and a flange 56 to the spindle 1, the flange 56 being on a shaft 55 on which one specimen 50 is mounted while the "sleeve" specimen 51 is mounted in a member 58 and urged against the specimen 50 by piston means 61 instead of the means 16 in the earlier described arrangement. For oscillatory tests, the housing 52 may be mounted directly on the frame 12 and the shaft 5 5 connected for oscillation to the crank 9. Torque measuring device Fig. 3 The spindle subject to torque has a lever 28 secured to it, the lever carrying an adjustable radius stop which engages a resilient element 31 of the torque gauge 15.

Abstract: 1453205 Feeding record tapes BURROUGHS CORP 8 Oct 1974 [5 Nov 1973] 43457/74 Heading G5R [Also in Division H2] To prevent damage to the tape during operation, particularly rewind, of a magnetic tape transport system, caused by failure of the power source 31 supplying the capstan motor 21 through a conventional speed control unit 33 and each reel motor through a respective conventional speed control unit 32, one of the reel motors, preferably the motor 11 driving the reel 13 normally supplying tape, is automatically connected to the capstan motor 21 when the supply fails, so that the latter motor is supplied by the back EMF of the motor 11 and thus runs synchronously therewith until the motor 11  stops. The winding 41 of a relay 34, having two sets of changeover contacts 35, 37, 38 and 36, 39, 40, is energized by the source 31 to connect the motors 11, 21 (of the D.C. permanent magnet type) to their respective control units 32, 33 through the contacts 35, 38 and 36, 40. If the source 31 fails, the coil 41 is de-energized and contacts 35, 36 change over to contacts 37, 39 to connect a braking resistor 42 across the winding 12 of motor 11 and also connect the latter winding across the winding 22 of the motor 21. Typical speed/time braking characteristics for the motor 11 are discussed, Fig. 2 (not shown), for various loading conditions of the reel when the supply fails. If desired, the motor 21 may be supplied subsequent to a power failure from a separate voltage generator coupled to the shaft of the motor 11, whose back EMF is then only applied to the resistor 42.
