Title: Improvements in or relating to direction finding devices
IPC: G01S3/46
Filed: 1969-09-09
Abstract: 1278665 Radio direction finding CHRISTIAAN HUYGENSLABORATORIUM NV 9 Sept 1969 [10 Sept 1968] 44397/69 Heading H4D  In a radio direction finding system a high directivity antenna 1 (Fig. 1) is rotatable about axis 2 and exhibits a response pattern A(#) where 9 = (2#d/#) sin # and d is the spacing of (2N+1) elements, # the wavelength and # the angle between radiating target and main axis normal to the intersecting centre line of 1 and its rotational axis 2. Antenna 1 is flanked by non-directional antenna radiators 3, 4 constituting an interferometer with response pattern B (#); the distance of their phase centre to the rotational axis being ¢(2N+1)d; connected to a hybrid circuit 5 elaborating the sum and difference signals The radiation pattern of antenna 1 is given by and it is shown that if the sum and difference signals #(#,t); #(#,t) are phase-detected with a coherent signal, e.g. from A(#,t) the detection products are given by and by determining the respective signs thereof and whether or not their absolute magnitudes exceed a threshold p = cos α, binary code digits are obtained as follows:- and for the high directivity antenna signal a digit is produced which is 1 for A# > q and 0 for A# < q. The code combinations generated by signals #<SP>1</SP>, #<SP>1</SP> are repetitive at period 2# = ¢(2N+1)# but are made unambiguous over an angle interval about the main axis by adding the code digit derived from A (#), and q is predetermined so that this digit = 1 over the angular interval, symmetrical about the main axis, which comprises 5 code combinations of the remaining 4 digits. The combination is unique and denotes accurate alignment of the antenna combination upon the target (Figs. 2, 3, not shown). Automatic level control is applied to the fixed signals, or they may be compared inter se instead of with a fixed reference; it being shown that an unambiguous code combination is generated over an interval about correct alignment. For transmission of a signal to irradiate a passive target for reflection, the high directivity signal may be used alone. The unique code combination may be utilized not only for indicating exact alignment but for gating the video channel of a P.P.I. in presence of the code to display only the centre of each target break.
Patent GB-1180819-A (GB)
Title: Improvements in or relating to Phototelegraph Receivers.
IPC: H04N1/36
Filed: 1967-10-02
Abstract: 1,180,819. Electric synchronizing. NIPPON ELECTRIC CO. Ltd. 2 Oct., 1967 [3 Oct.. 1966], No. 44693/67. Heading H2L. The speed of a photo-telegraphic receiver is automatically selected to correspond with the speed of transmission, an amplitude-modulated signal being demodulated to form rectangular pulses which are applied to terminal 1, a generator 2 providing a sawtooth waveform of which the crest value is proportional to the pulse interval. When the sawtooth voltage reaches a predetermined level, a voltage comparator 3 operated a multivibrator 5 through a differentiating circuit 4. An AND-gate 6 produces an output waveform if a pulse is present at the terminal 1 while the multivibrator 5 is in the operat d state. A circuit 7 stores the pulses from the gate 6 until a level detector turns on a transistor TR1 to energize a self-holding relay RL1. Incorrect operation of the detector 14 is prevented since the circuit 7 does not operate unless it receives several pulses in succession, these pulses having the same interval as the carrier signal. When energized, relay RL1 transfers the output from gate 6 to store 8, and closes contacts to energize a drum motor. The circuit 8 provides a time lag until the motor reaches synchronous speed whereupon a siliconcontrolled rectifier SCR1 conducts to energize relay RL2. The motor is then clutched to the drum, the clutch being used for phase matching. Thus, the circuits 1-6 detect the presence of a carrier signal, and, when such a signal is present, the motor is energized. The system is adapted to determine automatically the required drum speed according to the pulsed rate of the carrier signal by arranging the sawtooth generator 2, to feed two parallel trains of circuits 3-6, the voltage comparators of which are adjusted to detect different voltage levels corresponding to different pulse periods. If a low-speed signal is applied to the terminal 1 the gate 6 provides an output to energize relay RL1 for connecting the drum motor to an oscillator for operation at low speed. Alternatively, when a high-speed signal is applied to the input terminal, the gate forming part of the other train of circuits becomes effective to energize another relay so that the motor is connected to a source of higher frequency. In another embodiment, the speed of the drum motor is synchronized with the incoming signals by pole-changing.

Title: Copying apparatus
IPC: G03G15/04
Filed: 1970-09-21
Abstract: 1313015 Photographic projection apparatus XEROX CORP 21 Sept 1970 [22 Sept 1969] 44852/70 Headings G2H G2A and G2J In a photographic projection apparatus, as described, a xerographic copier, for imaging a stationary original, e.g. a book 68, onto a moving image receiving surface 10 utilizing a scanning lens 18 and a scanning light source 15, an original support platen 14 defines a corner with a support member 63 of the apparatus and the light source is substantially opaque, only having a single light transmitting aperture 72 arranged to direct a band of illumination forward of said lamp 15 towards said corner as the lamp is moved to scan the original for copying. A platen cover (not shown) is provided. The lamp is held by a carriage 71 movably supported between a drive shaft 58 having a helical groove (79) Fig. 6, (not shown) therein and a support rod 59. As the shaft 58 is rotated by the main drive of the apparatus in synchronism with the drive to a drum 11 carrying the surface 10, a pin (78) Fig. 1, (not shown) following the groove (79) causes the carriage to move. The carriage first rapidly accelerates to the scanning velocity, then moves linearly across the platen until, at the end of the scanning motion, it is rapidly decelerated to zero velocity. A faster return motion is imparted by rotation of the groove (79). A counterweight (88) is provided so as to overcome the moment of the carriage 71 about the shaft 58. The carriage also trips limit switches (74, 73) to energize and de-energize the lamp at the beginning and end of a scanning movement. More than one lamp may be provided Fig.10, (not shown), the apertures (72) of each directing light onto the same position of the platen. The scanning apparatus so described can look into corners or other inaccessible areas. An optical system receiving reflected light image from the scanned original comprises the horizontally adjustable scanning lens 18, two mirrors 19, 20 both of which are adjustably supported, and a slotted light shield 110 defining an exposure aperture 111. As shown, the system is arranged to give non-magnified images, but the lens may be positioned to give magnified images. The lens movement is synchronized with that of charged drum 11 Fig.3, (not shown), thus when the drum stops, the lens and light also stop. This means that the area of the drum adjacent the aperture 111 maybe continually exposed to ambient light, thereby affecting the photo-conductive properties of the drum. Accordingly, an automatic shutter (140) Fig. 4, (not shown) is provided, which shutter moves to close the aperture 111 when the drum surface is not in motion.
