Abstract: 1523539 Automatic voltage control SAWAFUJI ELECTRIC CO Ltd and HONDA GIKEN KOGYO KK 29 Oct 1976 [8 Nov 1975(2)] 45047/76 Heading G3R [Also in Division H2]  Automatic voltage regulation in a converter system supplying a load from an A.C. generator having field windings FW fed by excitation windings EW, is obtained by an automatic voltage regulation circuit 5 connected between the excitation windings EW and the field windings FW. Regulation is achieved by sampling the voltage across the load terminals X1, X2, and feeding the sampled voltage to a rectifier 20 followed by a bridge having three resistance arms 23, 24, 25 and an arm having a Zener diode 22, the output of the bridge AB being connected to a transistor Darlington pair 11, 12, controlling a second transistor Darlington pair 9, 10, transistor 9 controlling the current passing through the regulation circuit from the excitation windings to the field windings. Increase in load voltage causes the second Darlington pair transistor 9 to pass less current thus reducing the exciting current to the field windings FW and causing the voltage at the generator output to drop. Similarly a decrease in load voltage causes the exciting current to the field windings to increase thus raising the generator output voltage. Hunting is prevented by a delay circuit 13 associated with the resistors in the voltage regulating circuit.

Patent GB-1089680-A (GB)
Title: Improvements in or relating to spectrometric apparatus
IPC: G01J3/28
Filed: 1964-11-17
Abstract: 1,089,680. Photo-electric spectrometers. OFFICE NATIONAL D'ETUDES ET DE RECHERCHES AEROSPATIALES (O.N.E.R.A.). Nov.17, 1964 [Nov. 29, 1963], No.46724/64. Heading G1A. [Also in Division G2] A spectrometer comprises an input plate 13, collimator 10, dispersive system 11, collimator 12, output plate 14, photo-electric detector 15, circuitry 16 and output 17. The plates 13 and 14, which replace the usual entrance and exit slits, are such that if the dispersive system is scanned through a range including that of a monochromatic incoming radiation the output signal rises slowly from zero level at first, then rapidly up to a peak value and down again before falling slowly to zero. When the dispersive system is positioned for maximum transmissivity much greater light intensity falls on the detector than if slits are used. The plates have alternate clear and opaque zones limited by curves forming a pattern which does not recur in the direction in which the spectrum is spread. One form of such plate may comprise zones consisting of parallel bars of increasing width across the plate, the bars being perpendicular to the direction in which the spectrum is spread. Other forms of zone arrangements are similar to those described in Specification 1, 089, 680. In order to remove the effect of the lower intensity signal caused by the gradual increase and decrease in transmissivity over a range approaching and leaving the narrow band of rapidly changing signal in the neighbourhood of the position of maximum signal output the circuitry 16 includes a filter which attenuates the effect of slow variations in signal but not rapidly varying signals. Instead of the spectrometer arrangement of Fig. 8 the dispersive element may be a reflecting grating associated with a curved collimating mirror. In a modification of this arrangement a single plate carries both input and output plate elements, the opaque zones of the output element being formed as mirrors to direct the output energy to the detector. This modification incorporates an auto-collimation arrangement.

Title: Electric switch mechanisms

Filed: 1969-09-25
Abstract: 1277224 Automatic circuit breaker SIEMENS AG 25 Sept 1969 [25 Sept 1968] 47356/69 Heading H1N The linkage of an automatic circuit breaker is arranged so that the moment of the force acting on a pivoted latched lever 13 remains substantially constant from the time the contacts first engage. A handle 1 forms a toggle with a link 10, being moved overcentre into engagement with a stop 3 to close the contacts 4, 5. The lower end of the link 10 is coupled to a pivoted contact lever 6 by link 11 and to a pivoted latched lever 13 by link 19. In the open position (Fig. 2) link 19 lies above pivot 17 of the latched lever 13 so that opening spring 8 acts, through the linkage, to bias the lever 13 anticlockwise against a stop 18; this allows the latch to return to its retaining position. When handle 1 is moved towards the closed position (Fig. 1) joint 20 moves downwards past pivot 17 so that the moment of force on latched lever 13 is reversed bringing it into engagement with the latch 12. When the contacts first engage the force on the lever 13 increases abruptly and thereafter falls as the linkage 10, 11 moves towards the straight position. Since the joint 20 is still moving downwards, however, the lever arm is increasing and therefore the moment of the force remains substantially constant as does the pressure at the latch. Upon overload an electromagnet (not shown) is de-energized to release an armature 22 which strikes an arm 15 of the latch to release it. Lever 13 then turns clockwise allowing joint 20 to move to the left to release the toggle 1, 10. The springs return the mechanism and operating handle 1 to the condition of Fig. 2 automatically.

Title: Optical focusing arrangements
IPC: G02B7/36
Filed: 1966-10-24
Abstract: 1,142,064. Automatic lens focusing. BELL & HOWELL CO. 24 Oct., 1966 [24 Oct., 1965; 30 Aug., 1966], No. 47587/66. Heading H4D. [Also in Division G2] The Specification describes automatic lens focusing means, especially useful in camera apparatus. The main lens 27, which is to be focused on a film &c. 29, is slaved to an imaging lens 11, by means of co-operating racks 37, 33 and worm gear 41. Light from the object to be focused is nominally focused on to a lenticular screen 13, which is moved across the optical path, such that, due to the passage of the lens elements of the screen through the beam, a photo-cell 15 will receive pulses of light from the beam, unless the lens 11 is exactly focused on the screen 13, corresponding to the focusing of lens 27. The screen 13 may be rotated by a motor 19 in which case the screen may be circular as in Fig. 2, having radial lens elements 52 extending over all the disc or only over part thereof (Fig. 3, not shown). The phase of the alternating current which energizes motor 19 is compared with the phase of the output of the photo-cell in phase discriminator 23 and the resultant signal used to energize a servomotor 25 driving worm gears 41. The screen may comprise parallel cylindrical lenses 57, Fig. 5, and be oscillated in a direction perpendicular to the lenses by a solenoid 63, Fig. 4. If the lens 11 is spring biased to be normally at one end of its movement (Fig. 7, not shown), the phase discriminator may be dispensed with, and the amplified and integrated output of the photo-cell used directly to energize the worm drive motor. If the lens 52 or 57 focal length is greater than a predetermined value, the output of the photo-cell will give shallow nulls for other than the focused condition. To overcome this, lenses of different size are used (Figs. 8, 9, not shown), together with integration of the photo-cell output as in Fig. 7. The screen may comprise three radial cylindrical lenses (Fig. 12, not shown) co-operating with a cam which operates a switch when a lens crosses the beam. Operation of a switch opens a gate at the photocell output, thus reducing the effect of noise which may occur in the photo-cell output between said beam crossing times. The gated output of the photo-cell goes negative or positive, depending on whether the focal point of lens 11 is in front of or behind the lenticular screen. A negative or a positive bi-stable circuit is accordingly triggered, to provide the driving power for motor 25.
