Abstract: 958,069. Transistor sawtooth current generators; automatic phase control systems. MULLARD Ltd. Oct. 26, 1961, No. 38368/61. Headings H3A and H3T. [Also in Division H2] In a sawtooth current generator of the so called " retrace driven " type employing a silicon controlled rectifier as the switching device and in which during the long stroke the rectifier is non-conductive and energy is returned to the supply, part of the voltage across the output transformer during the long stroke is rectified to provide a D.C. voltage for semi-conductor devices in associated apparatus such as a television receiver or an oscilloscope. Fig. 1 shows a circuit for generating a saw-tooth current in a deflection coil L D , of the basic type described in Specifications 821,517 and 904,443 modified as described in Specifications 949,535 and 957,882 to minimize the magnetization of the transformer core and to quench the SCR. By the addition of components 8, 11, 12, part of the transformer voltage during the forward stroke is rectified to provide a supply of from 1-16 V. for the associated semi-conductor apparatus. The opposite polarity D.C. voltage may be obtained if a separate winding is used or if the SCR is of the opposite conductivity type. The Fig. 1 circuit is a selfoscillator in which timing is effected mainly by a capacitor 17 which is charged negatively during the flyback and which, during the long stroke (when the SCR is non-conductive), discharges through resistor 18. During this period C1 is also being charged. Capacitor 17 becomes completely discharged and then charges positively offsetting the feedback voltage from coil 15 until the combined effect of the charging of the two capacitors causes the SCR to conduct to produce the flyback, during which C 1  is discharged and 17 is charged negatively by the regenerative feedback coil L 2 . Synchronization is effected by a phase discriminator 22 which controls the charging of capacitor 17. In Fig. 4 timing is effected by a capacitor 26 which, during the long stroke, discharges through resistors 25, 27 and 28. This continues until the voltage at the left hand plate is sufficient to cause an SCR S<SP>1</SP> to fire. The recharging current for capacitor 26 now causes the output SCR S to fire. The recharging of capacitor 26 is effected resonantly through choke 24 and the SCR S<SP>1</SP> is extinguished when the capacitor is charged. Synchronization is effected by a phase comparator 21 which compares pulses from coil 23 with input pulses to produce a voltage for controlling the firing point of SCR S<SP>1</SP>.

Abstract: 976,037. Telegraphy. CREED & CO. Ltd. Oct. 3, 1963, No. 38955/63. Heading H4P. In a mechanical storage arrangement, the store presents sequentially each of a number of code combinations at a reading position. When all the combinations have been read the store is moved so that no code combination is in the reading position. The store comprises a drum 1 having pins 3 which represent twenty 5-bit code combinations. The message stored is that transmitted in response to a WRU signal. In order that the reading fingers 2 can be used in the transmission of keyed data as well as of the Answer Back, after the fixed message has been sent the drum is so positioned that no pins 3 lie under the fingers. To this end, in one embodiment, Fig. 2, the ratchet 8 used to step the drum is formed with a second ratchet 20. When the WRU signal is received cam 17 is rotated and arm 4 disengaged from slot 5, whereby the first code combination is presented to the reading fingers 2 by the action of pawl 10. When the twentieth character has been read, earn 17 stops, with rise 14 engaging follower 16, and arm 4 reengages. Slot 5 is wide and allows pawl 21, now engaging ratchet 20, to move the drum from the twentieth position to the rest position shown, at which there are no pins 3. In a second embodiment, Fig. 3, the store is movable axially against action of spring 25 by means of cam 24 and pin 27. The fingers, in the rest position, lie just to the right of the pin 3 positions so that when cam 17 first starts to rotate pin 27 pushes the drum rightwards, bringing the first combination under the fingers. As the drum is rotated it moves progressively to the right, the fingers being at the left-hand edges of the pins when reading the twentieth combination. When cam 17 stops in the position shown, pin 27 reverts to the low of cam 24 and the drum is urged to the left, or rest, position.

Title: Gamma scintillation camera incorporating a sensitivity correction system
IPC: G01T1/164
Filed: 1975-09-24
Abstract: 1528360 Sensitivity correction system for a gamma camera PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 24 Sept 1975 [27 Sept 1974] 39105/75 Heading H4F A gamma camera of the type comprising a scintillations crystal 2, Fig. 1, a light conductor 4, and a hexagonal configuration of nineteen photomultipliers Pn, is provided with an automatic system for the repetitive recalibration of the channel gains. The said system comprises an electroluminescent diode 8 serving to illuminate twenty four optical fibres, the end of each fibre remote from the diode abutting the light conductor 4 and being positioned one in the space formed between each three adjacent photomultipliers. Thus the reference light signal produced by the diode after passing through each of the said fibres is reflected from a reflector 21 to simulate the uniform illumination of the photomultiplier assembly. If the scintillator is formed by an NarI crystal, wherein the scintillation light is situated in the purple part of the spectrum, the reference light signal should preferably be chosen in this part of the spectrum, the diode then having a suitable filter. Considering photomultiplier P1, Fig. 3, the light incident thereon produces an electric signal which is amplified by amplifier Al to provide a signal S1 which is normally used by calculation network 6 to form, using also the signals S2... Sn, the deflection signals for a CRT. However, the present automatic system stabilizes each signal as regards amplification before it is applied to network 6. Thus, the signal S1 is applied to two comparators CI, CS. If the instantaneous gain factor is greater than an upper limit (V1 + #) or lower than a lower limit (V1 + #), wherein V1 is the initial gain, then a bi-directional counter CD1 counts up or down, as required. Depending on the binary value of the signals appearing on k outputs of said counter, resistors Rl 1 to R1k of a potentiometer are connected to earth or not via switches C11 to C 1k to stabilize the gain of the amplification branch, which produces a signal S1s. A generator supplies pulses is for the actuation of the diode. Any evaluation of the results must be avoided if a reference luminescent pulse coincides with a gamma particle, otherwise the calibration will be incorrect. Thus, there is provided a comparator CO co-operating with two bi-stable latching elements V1, V2 which memorize the state of the amplifier channel under consideration at the beginning and end of each synchronization pulse. One of the inputs to comparator CO is the signal S1, the other input being held at zero. The output of each element V1, V2 is fed to a NOR-gate p10, the output of which supplies one of the transfer conditions vl of a validation AND-gate pvl. The transfer conditions r2 to rn are also fed to gate pv1 together with the output of an exclusive-OR gate p11 coupled, via bi-stable latching elements VI, VS to comparators CI, CS. The gate pv1 thus prevents any validation of the counter CD1 if the gain is correct.
