Title: Improvements in making drawings, designs and the like
IPC: B41C1/10
Filed: 1944-03-24
Abstract: Planographic printing-surfaces are prepared by a process which is also applicable to preparing sheets of hydrolysable materials for differential dyeing or inking.  A surface of a hydrolysable cellulose derivative or a resinous ester has a design applied to it in an ester of a similar type which is less readily hydrolysed. The application to the whole surface of a saponifying agent produces a surface which can be used as a printing-plate, or can be dyed to produce a pattern. A sheet of cellulose acetate may receive a design in a dark coloured cellulose nitrate solution containing 10 grams of cellulose nitrate, 2 c.cs. of tri-o-cresyl-phosphate, 30 c.cs. phenyl acetate, 50 c.cs. methyl alcohol, and 4 grams methyl violet.  If desired, a small amount of a solution of gum sandarach in ethyl ether may be added, or litho varnish may be used instead.  The coated sheet is treated with a solution of caustic soda 10 grams, methylated spirits 50 c.cs., and water 150 c.cs.  The dyes used may be chlorazol Black B.S.; Cotton Blue; Congo Red (Colour Index No. 320) or Chrysophenine (Colour Index No. 365).  Malachite Green (Colour Index No. 657) may be used to dye the cellulose nitrate preferentially to the hydrolysed cellulose acetate.

Title: Coin controlled camera and photographic cabinet
IPC: G03B17/53
Filed: 1928-02-28
Abstract: 294,160. Photomovette, Inc., (Assignees of Semel, S. I.). July 19, 1927, [Convention date]. Coin-freed apparatus.- In a coin-freed automatic apparatus the camera is fitted with a rotary exposure shutter and means for taking a series of exposures on a sensitized surface which is synchronously fed past the lens. The coin completes an initial circuit through the motor which thereupon rotates a disc having a gapped contact sector for maintaining the circuit until one of the contact brushes enters the gap. In the apparatus described embodying the above provisions and other features forming the subjectmatter of applications 294,162, 294,163, and 294,164, a coin 59, Fig. 2, inserted in the receptacle, 20, Fig 1, outside the camera compartment 11 bridges contact plates 52, 53, Fig. 2, and completes the motor circuit through lamps 16 used for illuminating a client on the seat 14. When the motor 23 starts, a circuit in shunt across the coin is completed by brushes 46, 48 and 49, engaging a broken contact sector 47 mounted on a disc 42, Fig. 4, on the face of the driven wheel 28. On the shaft 29 of this wheel a second wheel 18 is also mounted, which drives a pinion 88 on a shaft 17. On this shaft 17 are cam feed discs 32, Fig. 5, for intermittently feeding the sensitive film strip from the roll 21, and gearing 38, 39, for synchronously driving the rotary sector shutter 36. The gear 18 is partly broken away at 89, so that the film and shutter-driving pinion 88 is not started until the motor has got up speed. During the rotation of the driven wheels 28, 18, a pin 65, Fig. 8, on the wheel 18 engages a lever 66 which operates mechanism to retract the spring- controlled plate 53, Fig. 2, of the coin mechanism and allow the coin to pass, thereby breaking the preliminary circuit through the, motor. The spaced brushes 48, 49 engaging the contact strip 47 enables the alternative circuit to remain closed when the gap 50 of the contact sector 47 passes the brushes and the motor runs until the gap 50 comes opposite the single brush 46, as shown in Fig. 2. The motor is stopped quickly by a brake 77 which is applied by the projections 65 engaging a, lever 83, Fig. 8, connected through spring- controlled connecting levers with the brake. Immediately the feed of the film ceases, prior to the motor stopping, a cam 84 on the shaft 29 directly operates a pivoted cutting blade 75 and severs the exposed film. To provide a timing adjustment of the disc 42 and the contact segment 47 upon the gear 28, the disc is adjustably mounted on the wheel 28 by slots 87, Fig. 4.
