Title: Automatic gain control circuit with delayed decay of the gain control signal
IPC: H03G3/20
Filed: 1964-10-27
Abstract: 1,028,356. Automatic gain control. VAN DER HEEM N.V. Oct. 27, 1964 [Nov. 29, 1963], No. 43708/64. Headings H3Q and H4R. In an automatic gain control circuit for suppressed carrier single side-band signals or C.W. telegraphy, stated to be also applicable to audio frequency compression and expansion, a delay is provided in the decay of the gain control voltage at the end of each signal period. Demodulated signals from demodulator 1 are applied to an A.V.C. memory 9, having a small charging but very large discharging time-constant, generating the gain control voltage, and also to parallel connected low and high pass filters 2, 3, respectively. The outputs from the filters 2, 3 are applied to a rectifier in a bridge circuit 4 which is such that its output has a first value when no or very weak signals are received but assumes a second value as soon as the signal attains a use. ful value; the time-constant is short for charging but long for discharging whereby the output does not fluctuate during short, e.g. syllabic signal intervals. As soon as the output from rectifier 4 exceeds the predetermined value, i.e. a useful signal is present, it causes trigger circuit 5 to reverse into operative condition X: the trigger output is differentiated in differentiating circuits 6, 7 so that sharp pulses occur at each reversal. The pulse occurring at the end of a useful signal, when the trigger circuit returns to its quiescent condition, causes monostable multivibrator 8 to assume its metastable position for a predetermined time interval, but if a useful signal reoccurs during the interval, trigger circuit 5 is again brought into the operative condition and multivibrator 8 is forced to return to its quiescent condition. The output of A.V.C. memory G can be short-circuited by means of a gate 10; this is controlled by trigger circuit 5 and monostable multivibrator 8 in such a way that short-circuit does not occur as long as trigger circuit 5 is in its operative condition or multivibrator 8 in metastable position.

Abstract: 1405487 Cutting and welding by fusion THORN ELECTRICAL INDUSTRIES Ltd 12 Sept 1973 [26 Sept 1972] 44494/72 Headings B3V and B3R [Also in Divisions B5 and G2] A workpiece is treated with laser radiation by focusing a beam of the radiation passing through each one of at least two mutually exclusive areas of the cross-section of the beam at a respective point 14, 15. In one embodiment, a parallel beam of laser radiation is passed through a converging lens 11 and a bi-prism 12 to produce two focal points 14, 15 on the workpiece. The position of the points 14, 15 may be varied by altering the distance between the lens 11 and bi-prism 12 whilst the amount of radiation received at each point 14, 15 can be varied by laterally moving the bi-prism 12. In other embodiments, three focal points are produced by replacing the bi-prism 12 by two spaced prisms (22, 23) (Fig. 2, not shown), or five focal points are produced by using four prisms (32-35) (Fig. 3, not shown) or nine focal points are produced by using four prisms (42-45) (Fig. 4, not shown) arranged in two pairs which are perpendicular to each other one below the other. One or more converging members 11 may be used to deviate the radiation away from the incident beam or to produce focal points which do not lie in the same plane. The workpiece may be metal or silica and may be bored, cut or welded by the laser radiation.

In the embodiment shown the sun wheel 28 meshes with wheels 29 rotatable about fixed axes, a ring gear 30 meshes with the wheels 29 and with planetary wheels 31 on the carrier 32, and a second sun wheel 21 driven directly by the input shaft 19 meshes with the planetary wheels 31. Increased torque on the output shaft causes relative angular movement between the crown cams 1, separated by balls 2, with consequent leftward movement of the cam driven by the intermediate shaft 27 and deflection of a lever 4 about a pivot 26. Such deflection of the lever 4, acting through a roller 5 and cam 6 rotates a shaft 7 carrying a weighted lever 8 and a gear wheel 10 which, through a pinion 11 and bevel gearing 12, 13, adjusts the disc 14. In a modification the sun wheel 21 driven by the input shaft and the pinions 29 are dispensed with, and the planetary wheels on the carrier mesh with a fixed ring gear and with the sun wheel driven by the crown cams 1.

Abstract: 1487075 Cameras ASAHI KOGAKU KOGYO KK 15 Oct 1974 [19 Oct 1973] 44653/74 Heading G2A A camera for use with interchangeable objectives and having a T.T.L. light measurement system which is selectively operative in full aperture and stopped-down modes include switch means arranged to be mechanically operated by the action of a movable member which in turn is operative in response to movement of an engaging member on a full-aperture light measurement type objective, such operations of the switch means disabling operation of the light measurement system in the stopped-down mode. The switch SNG is moved to a closed position by rotating full aperture objective 1 when mounted on the camera to prevent operation for stopped-down light measurement such rotation causing ring part 2a to engage ring bar 15 and a bar 10 on ring 4 to move an earthed part 11 to engage switch rod 18. The switch circuit comprises light receiving element CDS, differential indicating meter M, a switch SOS for selecting whether the circuit operates for full-aperture or stopped-down light measurement, and a slide resistor (RV), see Fig. 1 (not shown), which corresponds to the diaphragm adjustment and consists of a resistor 6 on the ring 4 and a slider 16 on the ring 12. When the switch SNG is closed movement of the switch SOS to the terminal S fails to energize a coil L2 of the meter M since the resistance R is earthed. This indicates that the switch SOS is in the wrong position since only coil L1 of the meter M will be energized and the meter will not function effectively. When a stopped-down objective is used the switch SNG is open and the meter can then be used. The resistor (RV) is in the position (S'R) in which it is not subject to the battery voltage and therefore movement of the switch SOS to the terminal O will result in ineffective operation of the meter M which indicates that the switch S.O.S. is in the wrong position, see Fig. 3 (not shown). The objective 1 may have a bayonet type mount.
