Abstract: 101,814. Joy, H. W. Jan. 26, 1916. Kinematograph apparatus.-Two intermittent feed-sprockets for the film are employed, and change-speed mechanism is provided by which either sprocket may be thrown into gear for black- and-white and for coloured views respectively, the speed of the supply and take-up sprockets and of the shutters and colour filter being correspondingly changed ; thus in the arrangement shown in Fig. 1, the film F passes from the supply sprocket S<1> to the take-up sprocket. S<4 >and round either the fast sprocket S<2> for coloured views or the relatively slow sprocket S<3> for black-and-white views, the shaft 19, carrying the removable shutter A and colour screen B, as well as the shafts of the sprockets S<1>, S<4>, being rotated at corresponding speeds. Figs. 5 and 6 show in plan and elevation respectively the preferred form of mechanism. The main shaft 6, worked by a pulley 12 or by a handle H and gearing 11, 5, carries two wheels 3, 16 and may be slid axially by a fork 23 into two positions. In the position shown, the sliding pin 2 drives the shaft of the one pin Maltese-cross device 8, which rotates the sprocket S<3> ; further, by bevel-gearing 7 it drives the shaft 15, and lastly, by toothed gearing 16, 14 and bevel-gearing, the shaft 17. The shaft 15 works the black-and-white shutter shaft, and the shaft 17 works the supply sprocket S<1> by mechanism described below. By pushing in the knob I on the shaft 22, the main shaft 6 is moved axially into its other position with the wheels 16, 14 out of gear and the wheel 3 in gear with the wheels 9, 13. The wheel 13 rotates the shaft 17, but at a higher speed than before, and the wheel 9 works the two-pin Maltese-cross device 10, which rotates the sprocket S<2> and, further, by bevel-gearing, drives the shaft 18, which actuates the colour shutter by mechanism described below. Shaft 15, Fig. 6, works the tubular shaft 20 carrying the black-and-white shutter A<1>, by bevel-gearing 23, 24. Shaft 18 works by bevel-gearing 25, 26 the shaft 19, which passes through the tubular shaft 20 and carries the colour shutter A and the colour filter B. Shaft 17 rotates the supply spool S<1> and by bevel-gearing 27 the take-up sprocket shaft 21.

It is stated that the combination of torsional elasticity associated with such twisting with linear elasticity gives a uniform elasticity along each span of the system. In the Fig. 5, embodiment the links are provided by short cylinders 11 instead of the rigid rods 6, 6<SP>1</SP>. A supplementary L-shaped link 14 may be used to connect the lower end of each hanger to the trolley wire so as to oppose twisting of the latter. In alternative embodiments the single trolley wire is replaced by two wires symmetrically disposed about the vertical plane of the messenger wire, the spacing therebetween being greater at support towers 4, 5 than at the centre of the span, and an intermediate wire is secured to the lower end of the hangers and supports the trolley wire in turn through supplementary hangers. The links are made smaller at the centre of each span than at the support towers so as to provide the desired moment arm for the torsional forces applied to the messenger wire, and the spacing between the links is also increased towards the tower to produce the desired variation in elasticity. A hanger may be connected directly to the messenger wire at the centre of the span. Adjacent links on opposite sides of a support tower 4, 5 may extend in opposite directions, as shown, or in the same direction if the messenger wire is rigidly connected to the tower.

In a process of electrophotographic image formation, wherein an electrophotographic recording medium having a suitably backed photoconducting layer bearing a pre-existing latent electrostatic image in which charge areas correspond to recorded image areas is exposed in the dark to a pattern of activating radiation in which the radiation areas correspond to image areas of a further latent electrostatic image to be recorded on said layer, a uniform electrostatic field of suitable value is maintained through the layer during exposure with the radiation pattern so arranged relatively to the pre-existing latent electrostatic image as to prevent destruction of the latter, whereby without affecting said pre-existing electrostatic image there is formed on said layer said further latent electrostatic image. In the preferred embodiment as shown in Fig. 2, a photo-conductive insulating layer 12 on a conductive base 11<SP>1</SP> is exposed to image forming light from an enlarger 22, and a conductive induction electrode 16 preferably supporting an insulating layer 17 is positioned above layers 11<SP>1</SP>, 12, while a voltage is maintained between layers 11<SP>1</SP> and 16 by means of a D.C. power supply 21 and potential divider 30. The polarity of the induced charge pattern depends on the position of the sliding contact of the potential divider. In a modification, layers 16 and 17 are made transparent and are carried by a transparent support so that the image forming light may be directed on to the photoconductive layer from above. To avoid loss of contrast in the image areas due to charge transfer (or silent discharge) during separation of the electrode 14 and plate 10, a voltage of approximately '6 med S 3 ' is maintained between these plates, where: 6 med is the median of the range of charge densities of the two image patterns, and S 3  is the elastance per unit area of the photoconductive layer.
