Abstract: 846,464. Dynamo-electric machine core mountings. ENGLISH ELECTRIC CO. Ltd. Jan. 23, 1937 [Jan. 27, 1956], No. 2735/56. Class 35. In a dynamo-electric machine, e.g. a large turbo-alternator, having mounted in a stator frame 11 a cylindrical laminated stator core 10 which when the machine is operating exhibits a slightly elliptical distortion rotating at the same speed as that of the machine rotor not shown, the core is supported in the frame through a plurality of pairs of diametrically opposite support units spaced circumferentially around the core and which do not by themselves offer resistance to radial movement of the core relative to the frame, diametrically opposite units being connected together through connecting means which offer substantially no resistance to diametrically opposed simultaneous movements of the parts of the units connected to the core but which substantially prevent simultaneous movements of the parts in the same diametrical direction. As shown in Fig. 1 the support units 12, 13 comprise cylinders 12a, 13a and pistons 12b, 13b respectively coupled to the stator frame 11 and the core 10, and the connecting means comprise oil-filled pipes 14 each interconnecting the radially inner and outer ends of diametrically opposite cylinders so that free unrestricted oil flow takes place to permit the elliptical distortion but movement in a single radial direction is prevented; similar pairs of tangential units 15, 16 and interconnecting pipes 17, 18 permit tangential components of the distortion but prevent rotation of the stator core 10. In Fig. 2 is disclosed a mechanical equivalent of the hydraulic system, and each unit comprises a pair of levers 18a, 18b pivotally connected together intermediate their ends and having their ends connected respectively to the core and frame 10, 11 and to links 19a, 19b, a similar pair of units being provided for operation in a horizontal direction. In another hydraulic embodiment, not shown, each unit comprises two oilfilled deformable chambers disposed between a beam rigid with the core and the frame.

Abstract: 634,545. Power ; voltage and current measurements. SPERRY GYROSCOPE CO., Inc. Jan. 30, 1948, No. 2819. Convention date, Sept. 17, 1943. [Class 37] [Also in Groups XL (b) and XL (c)] The voltage or current flowing in one direction only in an ultra high-frequency transmission line 11, Fig. 1, is measured by a meter 21 connected at one end of an auxiliary line 13 whose other end is connected to a terminating impedance 23, the two lines having equal propagation constants and being coupled together at a series of points extending over a distance greater than a wavelength and preferably equal to a plurality of wavelengths. As shown in Fig. 1, the coupling consists of probes spaced less than half a wavelength apart, and as shown in Fig. 2, the coupling consists of a narrow longitudinal slot 32. The meter 21 is connected to a crystal detector 16 and if the impedance of the line is known, may register power. The crystal 16 may be connected to the meter over a coaxial line 27, Fig. 2, whose inner conductor is enlarged at 33, 37, the lengths of the enlarged portions and the distance between them being quarter wavelengths, so as to form a succession of quarterwave lines having alternately large and small impedance which acts as an impedance transformer to provide a low pass filter and thus ensure that meter 21 is not affected by H.F. energy. Specification 625,378 is referred to.

Abstract: 536,311. Altimeters. HASLER AKT.-GES. WERKE FUR TELEPHONIE UND PRAZISIONSMECHANIK. Feb. 14, 1940, No. 2838, Convention date, Feb. 16, 1939. [Class 106(ii)] Comprises a recording instrument in which a pin operates at regular time intervals to punctuate a record strip, the pin being moved at right angles to the movement of the strip by a flexible driving member controlled by the barometer capsule. A hollow cylinder 4 is rotatable on a vertical axis 3 on a bed 2 carrying a bell-shaped housing 1. The cylinder contains in its lower portion a driving spring 5 which drives by means of a gear 6 and gears 41 ... 44 an escapement 17 to regulate the movement of the cylinder 4. A spring pawl 9 and ratchet wheel prevents rotation of the axle 3. A sheet 10 stored in a tube 11 is drawn out through a slot 12 over guide roll 13, plate 14, guide roll 16, sprockets 23, to a take-up roller 17. The sprockets register with holes in the sheet. A perforating pin 24 is fixed to an arm 25 attached to an endless flexible band 26 which travels over rollers 27, 28 arranged so that one course of the band travels in front and the other behind the sheet. The band is provided with holes 26<SP>1</SP> engaging a sprocket wheel 29 at the level of a support 14<SP>1</SP> which is provided with a vertical groove 30 which permits the sprockets to engage the holes without touching the support 14<SP>1</SP>. The sprocket is connected by toothed gears 31, 32, 33 with a vertical rack 34 hinged to a spring barometer 35 and guided at the upper end in a groove in a guide pin 36. A spring-urged toothed segment 38 engages the wheel 31 to take up any slack in the gears. The wheel 41 is rigid with a star wheel 45 against which bears a long pawl rotatable about a pin 46 by a spring 48. To the pin 46 is also pivoted a double-armed lever 47a the forked shorter arm of which engages a pin 47b on lever 47. The lever 47a is rocked by a spring and carries a hammer 49 and when the lever 47 slips off a tooth of the star wheel 45, the hammer 49 is carried to strike a lug 50<SP>1</SP> on a frame 50 pivoted top and bottom and hence to cause a rocking movement of the arms 25 and pin 14. and to be immediately withdrawn. A groove 53 is provided in the plate 14 under the place where the pin strikes. The apparatus may be put into and out of action by means of a lever controlling the balance. In a modification a non-perforated band operated by a link and gearing from the barometer is used. Spiral gearing may be introduced into the transmission to the flexible band so that an open scale is given to the instrument.

Title: Data signal sampling control
Inventor: WELLER DAVID CURTIS
IPC: H04L7/033
Filed: 1968-01-19
Abstract: 1,205,471. Automatic phase control. WESTERN ELECTRIC CO. Inc. 19 Jan., 1968 [20 Jan., 1967; 17 April, 1967], No. 2927/68. Heading H3A. In a system for synchronizing a train of sampling pulses with a data system, each data bit is sampled at three successive instants to derive an error signal which adjusts the phase relationship of the sampling pulses so as to urge one of them towards the centre of the data bit. A clock source 14, operating in synchronism with the incoming data signal at 12, generates pulse trains on lines 19, 24, 28 the phase difference between the trains being varied by the potentials on lines 17, 22. The trains actuate gates 29, 30, 31 which feed samples of the data bit to adjustable threshold circuits 32, 33, 34 which detect whether or not the sample exceeds the threshold set by the potential on lines 36, 37, 38. Circuits 32, 33, 34 include bi-stable circuits which are set to their " 1 " or "0" state depending on whether or not the threshold is exceeded. At the end of the third sampling period, gates 43 . . . 50 are enabled by an output from delay circuit 67 and a signal is passed through one of them, depending on the state of the outputs from circuits 32, 33, 34. Assuming the relationship between the pulses and the data bit are as shown in Fig. 5A, the outputs from the circuits 32, 33, 34 will actuate gate 49 and reversible counter 54 will be stepped forwards. The output from this counter is fed to a digital to analogue converter which feeds a control signal to source 14 to reduce the phase difference # to zero. Other logical combinations of outputs from circuits 32, 33, 34 result in counters 52, 58 being stepped to adjust the spacing T between pulses on the threshold E s  according to the table of Fig. 3 (not shown). The desired control signals may also be employed to control the local oscillator of the demodulator from which the signals on line 12 are derived, Fig. 6 (not shown).
