Patent GB-1411575-A (GB)
Title: Two-terminal electronic starters for fluorescent lamps
IPC: H05B41/04
Filed: 1972-12-20
Abstract: 1411575 Control circuits for gas discharge tubes COMPAGNIE DES LAMPES SA 20 Dec 1972 58955/72 Heading H2H A starting device for use with fluorescent lamps comprises a pair of terminals across which are connected at least one semi-conductor bidirectional switching element and a trigger circuit for rendering the switching element conductive during successive half cycles of an A.C. supply connected to the device, means being provided for rendering the trigger circuit unable to render the switching element conductive after a period sufficient to allow the filamentary electrodes of the lamps to be heated adequately to allow the lamps to strike. A fluorescent lamp L having filamentary type electrodes 2, 3 is connected to an A.C. supply by way of a ballast inductor S and a starting device 1 having two terminals 1a, 1b. Across the terminals 1a, 1b are connected in series a triac 4 and a heater resistor R 5  for a negative temperature coefficient resistor R 3 , such that the inductor S, the electrodes 2, 3, the triac 4 and the resistor R 5  form a series circuit across the A.C. supply. Across the terminals 1a 1b is connected a further series circuit forming a potential divider and comprising resistors R 1 , R 2 , R 3  and R 4  in parallel, and R 5 , the point 6 on the potential divider being connected to the gate of the triac 4 by way of a diac 5. A capacitor C 2  is connected across the resistor R 4  and a capacitor C 1  between a main electrode of the triac 4 and a point between resistors R 1 , R 2 . Upon switching on, the voltage developed across the capacitor C 2  in each half wave of the A.C. supply reaches a value which breaks down the diac 5 thereby triggering the triac 4. Current then flows in the electrodes 2, 3 of the lamp L and the heating resistor R 5 . The electrodes 2, 3 and the N.T.C. resistor R 3  continue to be heated until the resistance of the resistor R 3  decreases to such an extent that the potential at the point 6 of the potential divider falls to a value such that the charge on the capacitor C 2  is insufficient to break down the diac 5 and thus the triac 4 is not triggered. At this point the filamentary electrodes 2, 3 will have been heated sufficiently, and the non-triggering of the triac will result in the ballast S and the capacitor C 1  will go into oscillation to produce a high voltage pulse to strike the lamp L. Thereafter the capacitor C 2  charges insufficiently to cause conduction of the triac 4. Modifications of the trigger circuitry are described in which capacitors are added thereto and/or resistors dispensed with and modifications of the complete circuitry disclosed in which two triacs in series are used and a pair of fluorescent lamps utilized.

[Also in Divisions Gl and G3]  In a method for measuring the mass per unit of area of a sheet material in which a radiation source provides radiation in the form of a succession of events of different energy levels directed toward the material to be gauged, a radiation detector is located to receive radiation from the source after it has been affected by the material, a digital counter is coupled to the detector output for counting the events, and means are provided to produce from the count and from counts established by a reference sample and in the absence of material an indication of the weight per unit area of the material the mass absorption coefficient being determined in the process and being kept updated. This last named means may be one in which the indication as derived from the count in a predetermined time or from the time to achieve a predetermined count. The method may be used for monitoring a paper production process in conjunction with infra red moisture content monitoring equipment and the measuring signal may be used to produce a paper, of desired basis weight.

Bobbin support and rotation (Fig. 6A). Bobbin 26 is supported on two rollers 5 carried by a cradle 2 pivoted at 3 and counterbalanced by a weight 4. A driven grooved traverse drum 1 frictionally rotates the package, possibly initially by elastic spacing rings (74, Fig. 7A, not shown). Full package indication. As the bobbin fills the cradle 2 tilts until a projection 7 trips a micro-switch 9, causing a servicing unit 72 (Fig. 9), which travels on tracks 71 past several winding units, to stop adjacent the filled bobbin, and a framework supported by the carriage to approach the winding unit. Yarn Severing Device (Fig. 5). A severing device is carried by a doffing head 16 (Fig. 6A) which is vertically movable on the framework. The yarn 15 passes through a guide 216 and, on actuation of a solenoid 213, a lever plate 208 moves a pivoted blade 203 to cooperate with a stationary blade 202, severing the yarn. The supplied yarn is then sucked into a flexible tube 17 through an opening in the doffing head 16 (Fig. 6B). Doffing of Full Bobbin (Fig. 6C). The doffing head 16 is lowered, engaging cradle 2 to disengage the full bobbin from driving roller 1, and an arm 19 is pivoted to tilt cradle 2 further, so that the bobbin engages fixed plates 10, and is dislodged from the rollers 5 to a conveyor or a storage rack 11. Arm 19 is then withdrawn, allowing the cradle to rise until it again engages the doffing head 16. Supply of Empty Bobbin (Fig. 4B). An empty bobbin 26 from a hopper 25 is advanced by a motor-driven rack and pinion mechanism 106, 107 to be gripped between fixed fingers 109 and a movable finger 110 both mounted on a swingable arm 111 carried by the doffing head 16. A motor 125 pivots arm 111 carrying the bobbin 26 to the rollers 5 on the cradle, and releasing it (Fig. 6E). The yarn 15 now passes around the new bobbin on its path to the suction device. Commencement of Winding on New Bobbin. Doffing head 16 is raised, allowing the new bobbin to be rotated by driving roller 1. Yarn 15 now passes past the severing device on its way to the suction device, and is severed thereby. A jet of high-pressure air carries the yarn end onto the surface of the new bobbin so that winding commences. The yarn end may be caught in a notch 73 on the bobbin end (Fig. 7B) or by adhesive tapes 74 (Fig. 7C).

Title: Data processing apparatus
IPC: G11B20/18
Filed: 1979-03-05
Abstract: Data processing apparatus can simultaneously correct data in several channels in error in an advantageous manner. The apparatus encodes and records vertical parity checks in a first channel and encodes and records parity checks in second and third channels, or equivalent taken over the channels, in respective predetermined positively and negatively sloped directions. Upon readback, syndromes from the parity checks and the recorded data are obtained. Correction signals from at least two syndromes intersecting the same error in a known channel in error are formed. The values of the syndromes diagonally intersecting errors in the known channel are continuously modified as the errors are detected by inversion of the simple parity. Correction is attained by logically combining the correction signals with the original data of the known channel in error. Internal pointers to either first or subsequent channels in error are generated as a function of the bit position displacement in the in-channel direction between the occurrence of first and subsequent mismatches of vertical and diagonal syndromes. Internal pointers are generated either in the absence of or to supplement any external pointers.
Patent GB-2018696-A (GB)
Title: Hydraulic synchronising systems
IPC: B61F5/38
Filed: 1979-03-23
Abstract: Rotational movements of the bodies (12, 14) of a rail vehicle are synchronised by two hydraulic actuators (20, 22) interconnected by two conduits (50, 52). To keep the conduits full of oil, an accumulator (87) is connected to the conduits through two non-return valves (82, 84). To keep the actuators in step, even if leakages occur, a spool valve (44) is provided, which opens correcting flow paths in dependence on the difference, if any, between the positions of the pistons (24, 25) of the two actuators. Such a flow path bypasses one or other of the non-return valves (82, 84), so that the direction of flow is controlled by the other non-return valve. As soon as the external forces on the bodies are such as to bring the actuators back into step, a correcting flow occurs. A spring device (54) allows the actuators to move out of step, under spring control; no correcting flow occurs under these conditions. <IMAGE>
