Title: Circumferential and lateral web registration control system
IPC: B65H23/188
Filed: 1971-10-12
Abstract: 1349470 Rotary printing press HARRIS-INTERTYPE CORP 12 Oct 1971 [15 Oct 1970] 47461/71 Heading B6C [Also in Division G3] Registration of printed matter on a web is controlled in the longitudinal and lateral directions by a system responsive to separate registration marks, the signals produced by the marks for one direction being corrected for errors introduced by lack of registration in the other direction. In the embodiment four colours are printed on each side of a web 20, the control for one side only being shown. One cylinder pair is taken as a reference and its registration marks are detected by a photo-electric device 36a, the marks from the other cylinders being arranged transversely across the web and detected by similar detectors 36b ... 36d. The marks are as shown in Fig. 2, the lines 24a, 28a being transverse to the web for longitudinal (circumferential) registration and the inclined lines 24b, 28b being for lateral registration. The detectors scan along line C and hence produce successive pulses as the marks pass beneath them, but whereas the time interval between pulses from reference and control detectors 36a, 36b in respect of the transverse marks is dependent only upon longitudinal registration error d 1 , the interval between pulses in respect of the inclined lines will depend upon registration errors in both directions. To compensate for this the longitudinal error signal is algebraically added to the signal derived from the inclined lines to yield a true lateral error signal. These error signals are produced in respective counters to which are gated clock pulses related to the speed of the rolls. Logic circuits (Fig. 4, not shown) are arranged so that, at sampling intervals, the gates to both counters are opened by the first pulse from 36a or 36b and closed by the second. The counter counts up or down during this time according to which detector is activated first (to distinguish lag and lead errors). The next pair of pulses (produced by the inclined lines) gate the lateral error counter only so that the number in this counter only is the sum of the two gating periods. The counts are used to operate respective stepping motors 37, 39 to correct the position of the cylinders.

Filed: 1973-10-23
Abstract: 1444959 Moving target firing simulators J L HAULT 23 Oct 1973 [3 Nov 1972] 49396/73 Heading F3C A simulator has a weapon with an electromagnetic radiation pulse source actuable directly and immediately by a firing mechanism, a convergent optical system for concentrating the pulses into a beam, and an object located between the source and the system to determine the shape and size of the beam, the axis of the beam being displaceable through a predetermined angle; and a target having radiation detectors located on one or more faces thereof such that when the target is a predetermined distance from the weapon and when the beam axis impinges on any part of a predetermined area (comprising a major portion of the or each face) at least one detector is irradiated. In the weapon the source is a light pulse generator 22, Fig. 3, with a reflector 24 having a screen 25 with an aperture 26 forming the object in front of the generator 22. The screen may be vertically ajdusted by a screw 27 and a vertical slot 20 in the screen. This vertical adjustment sets the vertical angular displacement of the transmitted pulse beam from a convex lens 38. For horizontal angular beam displacement, a sleeve 39 (locked by a screw 44) is rotated to cause a member 45 to slide a block 31 and the screen 25 attached thereto horizontally along a slot in a fixed disc 34 having a large aperture 36. Alternatively in Fig. 13, the screen 25 is fixed and a triangular prism 61 is rotated in the horizontal and vertical planes, for similar beam displacement, by rotation of screw-threaded rods 68, 66 respectively. Since the pulses emanating from the generator 22 are appreciably faster than the speed of a simulated projectile, target speed relative to the simulated projectile velocity is accounted for by an instructor by horizontal beam displacement in the opposite direction to target movement to provide simulated target movement during simulated projectile travel. Vertical beam displacement is for range simulation. The radiation may be in the form of visible light, ultraviolet or infra-red pulses, or in the form of a laser. The target in model form has a plurality of photo-electric cells 54, Fig. 12, the number being kept to a minimum but ensuring that the beam 51, even if its centre is within the boundaries of the target face presented to the weapon, triggers a cell, but if its centre is outside the target face then no cell is triggered. To aid reduction in the number of cells, the beam cross-section depends on the target profile and, to this end, different screens 25 with varying apertures, or a diaphragm aperture screens, or a rotatable screen with various apertures, may be used. When a cell 54 is actuated the signal is amplified, passed through a variable delay to simulate projectile flight time, and a relay to affect the target motor and to possibly produce visual and/or sound effects of a hit; the signal passes through a fixed delay to a relay to cancel the signal from the first relay to the motor control.
