Title: Display systems
IPC: G06F3/033
Filed: 1975-10-06
Abstract: 1506930 Matrix displays WESTERN ELECTRIC CO Inc 6 Oct 1975 [9 Oct 1974] 40783/75 Heading G5C A display system comprises an array of display cells having inherent memory and means for applying to the cells signals which cause light to be emitted by "off" cells only but which do not cause them to store sufficient charge to place them in the "on" state. The cells may be gas discharge type or S.C. elements each with a memory element. The signals comprise a positive pulse e sw  terminating a time Tr before the subsequent negative sustaining pulse V s  where T r  is the memory recovery time. This produces a light pulse SW. The pulse e sw  is combined with an erase pulse e sc  applied immediately before the sustain pulse. This causes the light pulse se to occur instead of the pulse s which would otherwise have been caused by the sustain pulse. The combination is scanned across a display panel and allows the position of a light detecting pen to be determined since either the occurrence of a pulse from an "off" cell or the displaced pulse of an "on" cell is sensed, e.g. by a computer. The information is used to identify a location or to modify the display. The panel may include means for varying the timing of sustain pulses to keep alive cells according to the remoteness of the display cell to be addressed. In this case the pulse e sw  is arranged to follow the discharge of the keep alive cell and hence is also varied according to its position, Fig. 7F (not shown).  The pulse e sw  may be added to the preceding sustain pulse. The combined pulse may be applied to all cells in a group, e.g. a row. Panels with polar electrodes are referred to.

Abstract: 1404657 Automatic control of electric motors SIEMENS AG 4 Sept 1972 [4 Sept 1971] 41011/72 Addition to 1290962 Heading G3R The control system described with reference to Fig. 12 of Specification 1290962 is modified to provide the following additional features:- (1) the output signal of the controller 10 for the rectifier 2a is combined in an adding device 14 with the time differential of the desired value applied to the input of this controller, whereby the change in the direct current Igl produced by a change in the desired value occurs in step with the change in the phase angle produced by a change in the desired values to the angle switch WS controlling the inverter 2b. The time differential of the desired value is produced by a differentiating member 13 whose output is connected to the device 14 through a changeover switch 22 and whose input receives the desired value signal produced in a component computer 4 which performs the functions of members 5, 5', 6 described in Specification 1290962, (2) the time differential is alternatively supplied, by changeover of switch 22, from a multiplier 24 which receives from the computer 4 signals representative of the sine and cosine of the angle between the stator current vector and the momentary position of the rotor field axis, Fig. 1 (not shown) and receives from a transducer 15 the differentiated values of the stator current desired-value components I w * and I b <SP>*</SP>. The transducer 15 comprises delay members, integrators and inverting amplifiers, Fig. 3 (not shown) and functions to convert sudden changes of desired-value signals I w **, I b ** to continuously varying signals I w * *, I b **, the former signals being obtained from speed and field controllers 18, 19 fed with error signals produced by respective comparators receiving a speed reference signal n* and output signal n of a tachogenerator 32 and a field reference signal #* and a signal # which is proportional to the magnitude of the rotating field vector Fig. 1 (not shown) and is produced by the computer 4, (3) the voltage U 1  is caused to follow the voltage U 2  to rapidly counteract disturbances caused by changes in load on the motor, the adding device 14 being supplied with a signal U 2 ' to produce the desired control of U 1 . Due to the high harmonic content of the voltage U 2 , the voltage U 2 ' is in the form of a calculated harmonic-free signal which corresponds to U2 and is produced by two series-arranged multipliers 30, 31 fed with the actual speed signal n, the calculated signal and the signal representing the sine of the angle between the stator current vector and the momentary position of the rotor field axis. The composition and functions of members 4, 24 are described, Fig. 3 (not shown) and the motor vector diagram, Fig. 1 (not shown) is analyzed for changes in the desired values I w *, I b *.

Title: Electronic Timing Device for Cameras
IPC: G03B9/64
Filed: 1968-08-28
Abstract: 1,187,724. Shutter delay and timing device. PRONTOR-WERK ALFRED GAUTHIER G.m.b.H. Aug.28, 1968 [Sept.2, 1967], No.41024/68. Heading G2A. A camera shutter has electronically controlled delayed action and exposure timing and an indicating lamp is provided which operates during the delay time. . Without delay action Cocking of the camera rotates a plate 4 anti-clockwise into the position shown where it is retained by one arm of a spring- urged double arm lever 8 and an armature 16 is moved into contact with an electromagnet 18 by means of levers 20 and 14. Depression of the shutter release lever 10 closes a switch S 1  and effects the rotation of the lever 8 to release plate 4 which causes a thrust pawl 5 to engage a projection on the sector ring 6 which thereupon rotates to open the shutter. This action causes a trapping lever 12 to lock the shutter in the open position and causes a switch S 3  to remove a short circuit from condenser C 2  which then begins to charge through, a photo-resistance F until a voltage is attained which triggers a circuit comprising transistors T 4 , T 5  T 6  and T 7  to de-energize electromagnet 18 whereupon armature lever 14 rotates under the action of spring 17 to rotate the trapping lever 12 and allow closure of the shutter. With delayed action Delayed action is effected by moving lever 22a to the position shown whereupon switch S 4  is closed while armature 27 is held against electromagnet 29 and a projection 22b is moved into the path of the sector ring flap 6b. On operation of the shutter release 10, the battery E is connected across points A and B to initiate signal lamp operation Figs. 3 and 4 (not shown). The sector ring 6 moved only a small distance S before being arrested by the projection 22b of the lever 22 but this is sufficient to cause a switch S 2  to remove a short circuit from a condenser C 1  allowing it to charge until a sufficient voltage is attained to trigger a second trigger circuit to de-energize electromagnet 29 whereupon armature lever 24 is free to rotate to remove projection 22b from the path of sector ring 6 allowing it to open the shutter. Rotation of lever 22 opens the switch S 4  to terminate the signal. Exposure timing is then as described above. The lamp signal may be steady or flashing. Other signalling devices may be used, for example an acoustic device.
