Title: Machine for the continuous projection printing of moving picture films
IPC: G03B27/475
Filed: 1935-01-18
Abstract: 439,334. Kinematograph projectionprinting apparatus. DALOTEL, M. A., 29, Rue Pasteur, Colombes, Seine, France. Jan, 18, 1935, No. 1743. Convention date, Jan. 19, 1934. [Class 98 (i)] [See also Group XXVI] In a machine for the continuous projection printing of a series of positive copies from one or more film negatives, the negative and copy films are disposed side by side and a series of neighbouring sections of the negatives are projected separately by a series of separate objectives on to the copy films, illumination being obtained through a common condenser and a series of lenses placed between the condenser and the film. The negative film 1 and the sound negative film 2 are projected through windows 3, 4 respectively, on to the positive films 6, 6<1> ... provided with windows 7, 7<1> ... 8, 8<1> ... stepped in height. The sprocket wheels 10, 11 of the negative films and the sprocket wheels 12, 12<1> ... of the positive copy films are mounted on the same shaft 9. Illumination is obtained by a lamp 13 placed at the focus of a common condenser lens 14, and a series of small lenses 15, 15<1> ... are placed between the lens 14 and the negative films, the latter being guided between consecutive pairs of rollers 21-21<1>, 21<1>-21<2> ... forming the film windows. The beam of light then falls on to a totally reflecting prism 16 with vertical edges and attached to a totally reflecting prism 17 with horizontal edges, whereby the beam suffers three internal reflections before passing through the objective 18 and prism 19 on to the copy film. The picture film and the sound film may both be projected by the same prism, and a single illuminating device may be used for the two films. Adjustment of the intensity of the beam is obtained by arranging in the path of the beam a slot of variable width, or an adjustable set of glasses with different transparencies. The adjustment is effected by a compound eccentric comprising a fixed axis 43, a number, for instance, five eccentered muffs 44, one inside the other and surrounded by a plate 41. Each muff is ended by a toothed pinion 45, which meshes with a rack 46, operated by an electromagnet 47. Each rack 46 upon actuation by the electromagnet turns the eccentered muff through half a revolution, and the eccentricities are chosen, for example, in the ratio 1, 2, 3, 6, 12, so that a series of displacements of the plate 41 represented by consecutive integers may be obtained by selection.

Filed: 1976-01-15
Abstract: 1516661 Endless conveyers MOLINS Ltd 15 Jan 1976 [17 Jan 1975] 2075/75 Heading B8A A stream of cigarettes on an endless slatted conveyer 2 is divided into batches by means of divider plates 12 which project upwards through special slats 2b of the conveyer at a predetermined point of the conveyer path and then continue to project upwards through the cigarette stream as shown by the lines 60, 62, 64 of the top of a divider plate 12, the stream being compressed in the region of the said lines by means of a plate 44 in order to prevent excessive displacement of the cigarettes due to an upwardly-moving divider plate 12. The region of the compression exerted by the plate 44 terminates upstream of the position at which a divider plate 12 fully projects through the stream. The conveyer 2 comprises two parallel endless chains 4 (only one shown) which are interconnected by slots 2a, 2b, the chains 4 passing around sprockets 6 and driven sprockets 8. A guide channel 16, in which rollers 14 attached to the inner ends of the divider plates 12 are received, extends below the upper run of the chains 4 from a first end 16a to a second end 16b. In the region of the upper run of the chains 4 the channel 16 is adjacent thereto but from the sprockets 6 back to the sprockets 8 the channel 16 diverges from the lower run of the chains 4. A divider plate 12 which is projecting upwards through the upper run of the conveyer 2, as shown in Fig. 1A, is carried along by its associated slot 2b, but after passing about the sprockets 6 that plate 12 is progressively withdrawn inwardly of the lower run of the conveyer 2 due to the divergence of the channel 16 from that conveyer run, and as that plate 12 passes about the sprockets 8 its outer end is inwardly of the slots. The rollers 14 of that plate 12 leave the channel 16 at its end 16b and pass into a vertically movable channel member 18 which raises the plate 12 such that its upper end traces the above said locus 60, 62, 64 as it again moves upwardly through the cigarette stream and its roller 14 enter the channel 16 at 16a. The channel member 18 is attached to a parallelogram linkage 20 which is raised and lowered by means of cams 32, 34 which respectively engage rollers 28, 30 of the linkage 20, the cams 32, 34 being driven by a shaft 36 which, in turn, is driven by a drive gear 38 attached to one of the sprockets 8. The shape of the cams 32, 34 determines the locus 60, 62, 64 and also cause the channel member 18 to be lowered back to the channel end 16b after a plate 12 has entered the channel 16 at 16a. Instead of the plate 44 a driven endless band (not shown) could be used.

In a labelling-machine the stack 9 of labels is contained by two side bars 4, two top bars, and two bottom bars, all the bars having front ledges or claws 11 against which the front label 12 is pressed by a pressure pad 13. The bars 4 are carried by side members 3 adjustable vertically on four columns 2 mounted on a base 1, and the top and bottom bars are carried by a bridge member and adjustable supports, respectively, mounted on the columns 2. A transverse lever 15 is pivoted at 14 to the pressure pad 13, and has a head portion 16 slidable along a bar 17 carried by one of the side members 3. A cord 22 is attached at 24 to the lever 15, passes around a pulley 23 mounted on the member 3 at one end, and then along the member 3 where it is attached to a drum 19 rotatably mounted at the other end of the member 3. The drum 19 contains a coiled spring and exerts tension on the cord 22 to urge the lever 15 and pressure pad 13 into contact with the end of the stack 9 of labels. In order that the front label 12 may be forced back slightly from the claws 11 to assist its removal from the pile by an adhesive separator, the head 16 of the lever 15 is a slack fit on the bar 17, and is cut away, as shown, on opposite sides to allow the lever and pad 13 to be rocked back about the head 16 as pivot. A knob 18 on the head 16 facilitates hand manipulation of the lever and pad when fresh labels are to be inserted in the stack 9. Where there are two or more stacks, they are arranged vertically staggered to allow replenishment thereof.
