Title: Method of manufacture of colour picture tubes
IPC: H01J9/227
Filed: 1973-01-15
Abstract: 1416751 Colour televisions tubes RCA CORPORATION 15 Jan 1973 [14 Jan 1972] 1935/73 Heading H1D In a photographic method of fabricating the phosphor pattern of the screen of a shadow mask colour tube, in which a photosensitive coating is exposed to a small area light source through the shadow mask misregister is reduced by first exposing the screen to the light source through a first lens, of continuous surface contour, and a first filter, designed to minimize misregister in a first zone of screen and to provide maximum brightness in that zone and a varying brightness over a second zone, and then exposing it through a second lens of continuous contour and a second filter designed to minimize misregister in the second zone and to provide a maximum brightness in that zone and a varying brightness over the first zone. The brightness variations produced by the two filters are arranged to give a substantially uniform total exposure over the boundary between the zones. As described, the first zone covers a central strip of the screen, the second zone being formed by the two remaining outer portions (Fig. 3, not shown), but more than two zones, and associated exposures, may be employed. The correction lens associated with a given zone may be designed by measuring the misregister at a plurality of points over the screen when using an approximate correction lens, and then weighting the misregister vectors over the given zone relative to those outside it for the design of the accurate lens. Different lighthouses, or a single adjustable lighthouse, may be employed for the different exposures, for which the light source may be at the same or different distances from the axis, and first or second order printing may be employed, i.e. the light source position is, such that, for a given colour dot the printing light ray and the the relevant electron beam pass through the same, or adjacent mask apertures, respectively. The method may be. employed for a phosphor dot or line screen, and for black-matrix or non- matrix screens.

Jan. 23, 1932, No. 2129. [Class 108 (ii).] In a six-wheeled motor vehicle having a pair of rear axles only the foremost of which is a driving axle and in which the rearmost pair of wheels are mounted on swivelling stub axles independent of those associated with the front steering wheels, the two rear axles are so connected to the chassis frame by two pairs of springs and a pair of balance levers that the rearmost axle and stub axles are automatically tilted so as to give the corresponding wheels a castor action when the vehicle is being driven in either direction. The rear axles s, g are fixed to pairs of springs n, m the adjacent ends of which are connected by links u to balance levers v pivoted to the frame k, the other ends of the springs being connected as by shackles to the frame at t, t<1>. The rearmost wheels e, e<1> rotate on stub axles connected by swivel pins f, f<1> to the axle g, the stub axles being preferably connected together bv arms h and a link i. Normally the swivel pins are vertical but when the vehicle is being driven forwards (say) the torque reaction on the driving axle s tends to turn this axle clockwise when viewed from the near side of the vehicle and this rotation is transmitted through the balance levers to the axle g causing this to turn counterclockwise as shown in Fig. 4, thereby giving the wheels e, e<1> a castor action. When the vehicle is driven in the reverse direction the tilt of the rear axle g is reversed.
