Patent GB-496165-A (GB)
Abstract: 496,165. Electric signalling systems. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 1, 1938, No. 41. Convention date, Jan. 2, 1937. [Class 40 (i)] Vibration or eccentricity and transverse shift of a rotating shaft or other body are indicated by measuring the output of an electric generator of relatively high frequency the rotor of which is fixed to the shaft and the stator fixed independently thereof. The output of the generator which is modulated at relatively low frequency by vibration is rectified, the alternating component of the rectified current being measured to indicate the vibration whereas the direct current component indicates the transverse shift. As shown in the Figure, the stator 12, which may however be a permanent magnet, has a direct current energizing winding 13 and toothed polepieces carrying generating windings 14, co-operating with a toothed rotor 11. The output of the generator after rectification at 15 is fed through filters 16 to remove residual high frequency and applied to a measuring instrument 17. The direct current component may be blocked by a condenser but, as shown, it is balanced by battery 18 and potentiometer 24 when switch 26 is moved into its horizontal position, the instrument 17 then indicating the amount of vibration. If the switch is in the position shown, the instrument, shunted by resistance 26<1> to reduce its sensitivity, indicates the direct current component representing transverse shift. The movements of instrument 17 may be recorded.

Abstract: 1,202,108. Counting sheets. C. G. PALMER. 22 Oct., 1968 [19 June, 1968], No. 49964/68. Heading G4D. A device for counting over-lapping newspapers comprises a pair of sensors which operate the counter when the leading sensor is rocked by a newspaper. In a first embodiment, Fig. 1, the sensors 14, 16 are connected by links to a plate 26 held normally in vertical position. When a newspaper 13 rocks the sensor 14 counter-clockwise the plate 26 is likewise rooked counter-clockwise (Fig. 2) so that a plate 40 interrupts the light falling on a photo-cell 39. When the sensor 16 is rocked the plate 26 resumes vertical position at a lower level (Fig. 3) permitted by pin-andslot connection 28, 29. The system enables newspapers of varying thickness to be counted (Fig. 4). Magnets 44, 45 resist initial movement of the plate 26 in either direction. In a second embodiment, Fig. 5, rocking of the leading sensor 50 swings plate 63 counterclockwise and link 67 clockwise so as to bring the top end of 67 into proximity with a magnetic pick-up 66, movement of the second sensor restoring the apparatus. In a third embodiment (Fig. 7), the links carry mirrors, detection of a newspaper causing reflection of light into a collector on to a photocell.

Abstract: 1,161,208. Rolling. DAVY & UNITED ENG. CO. Ltd. 21 Nov., 1966 [25 Nov., 1965], No. 50166/65. Heading B3M. [Also in Division G3] A four-high prestressed rolling mill includes spacers which are arranged between the working roll chocks, and which are automatically adjusted to maintain the thickness of a rolled product constant. For each housing 12 the spacers are in the form of screws 27 which are threaded into nuts 28, fixed in an upper working roll chock 21, and abut load cells 33 in a lower chock 18. Each screw is rotatable to vary the spacing of the chocks 18 and 21, by means of gearing 30-32, splined shafts 37 and 41, and a common driving motor 43. A prestressing cylinder 24 provides a force in excess of the rolling load. Signals are taken from the load cells 33, from position transducers 44 to give a measure of the roll spacing, and from a transducer 51 to give the prestressing load. These signals are processed and compared with a desired strip thickness set on a potentiometer 56. Any error signal is fed to the motor 43 to control the movement of the screws 27. It is preferred to maintain the prestressing force constant, in which case the signal from transducer 51 is compared with a reference set at 67, any difference signal being applied to a control valve 26 to maintain the pressure at the reference value. The value on the potentiometer may be automatically changed, however, in order to keep the difference between prestressing and rolling loads within a given low range.
