Abstract: 1377822 Simulator display SINGER CO 24 Oct 1972 [26 Oct 1971] 48885/72 Heading H4F In the vertical raster television simulation of the view, Fig. 6, seen by an operator of an amphibious vehicle, the image of the land is produced by a colour television camera 23, Fig. 2, scanning a model 26, whilst the image of the sea and waves is produced by velocity modulation of the vertical scan in accordance with controlled adaptations of set wave profiles stored on a second model 37, also viewed by a second camera 35. The land 24 in model 26 is in full colour whereas the water is black with addition of one colour-here blue-with an intensity inversely proportional to the water's depth. A water detector 31 thus determines when the red, blue and green video signals on line 29 contain no red or green and switches over scan feed switch 51 from the standard constant velocity sweep signal (generator 49) to the variable velocity sweep signal from modulator 47. The set wave profiles coded on to model 37 in terms of elevation indicating variations of black and white give rise to video signals which control modulator 47 and are adapted at modulator 46 in dependence on the depth of the water as detected by logic 39 from the amplitude of the blue video signal in the output of camera 23, and also in dependence on conditions, e.g. wind, determined by the instructor at station 17. The period of the displayed waves can be varied by raster control 43 by controlling the content of the area scanned by the camera 35-e.g. scanning a small area C, Fig. 4, encompassing two waves gives a scan signal which when stretched to the length of the display scan gives two long period waves. The detection of water at 31 causes the colour blue to be added to the video signal fed to the display 21. The video signal fed to the display 21, both land and water, can pass through a fog simulator or visibility efiects logic 33 comprising a limiter which operates at a predetermined simulated range, (length of scan).

In operation, as the driving shaft 1 rotates, the eccentric discs 2, 3 alternately pull the links 6, 7 to oscillate the driven shaft 10, the links 6, 7 alternately unwrapping from and wrapping around the cams 8, 9 as the eccentrics 2, 3 alternately move upwards away from and downwards towards the driven shaft 10. By varying the eccentricity of the discs 2, 3 and/or the shape of the cams 8, 9 the angle of amplitude and the speed of oscillation of the driven shaft 10 may be readily varied. Where the angles of oscillation of the driven shaft 10 is less than 180 a single cylindrical cam may replace the two cams 8, 9. Each of the flexible links 6, 7 may comprise a single continuous flexible cord (as shown) or may each be constructed as a solid intermediate link with two flexible cords adapted to be wrapped about the associated eccentric disc and cam. The position of the guide pins 4, 5 may be varied (Figs. 3 to 6 not shown) to enable the relationship i.e. positions etc. of the driving and driven shafts 1, 10 to be readily varied. As shown in Fig. 2 the oscillatory movement of the driven shaft 10 is transmitted to the shuttle shaft 25 by a belt 27 arranged around pulleys 20, 26 on the shaft 1 and the shaft 25 respectively, the belt passing around a guide roller 28, the rotary driving shaft 1 additionally reciprocating the needle bar 12 via a crank arm 14 and links 15, 16, an oscillatory link 17 being connected to the needle bar 12 for effecting zig-zag sewing operations.
