IPC: G03B17/53
Filed: 1928-10-25
Abstract: 324,133. Foulis, W., and Casani, S. Oct. 25, 1928. Automatic apparatus; enlarging, copying, and reducing.-The negative produced in automatic photographic apparatus, whilst still wet, is photographed to form a positive reproduction or enlargement in a camera forming part of the apparatus. The negative, held in a rigid slide, drops after development into position in the camera 4, Fig. 2, depressing the lever 6 which closes a contact 7 producing a flash of light in the lamp 8 and exposing the positive held in a. slide already in position in the camera 4. Closing the contact also actuates an electromagnet 9, closing the clutch 10, 12, Fig. 1, and connecting a continuously-rotating shaft 11 to a rope drum 13. The rope winds up, moving a plunger 14 which pushes a fresh slide filled with positive paper from the magazine 5, and discharges the exposed slide down the shoot 15. The plunger moves a rod 16, which releases the arm 6 through the lever 17, allowing the negative to fall and breaking the circuit of the electromagnet 9. The rope drum 13 and plunger 14 are returned to initial position by a weight 18. The slide with the positive passes in succession through the developing, fixing, and washing tanks 19, 20, 21 and down the shoot 23, Fig. 2, where the paper is removed from the slide and discharged. The printing light 8 may be adjusted towards and away from the negative. Alternatively the contact may be made by the metal body of the negative, the positive slide may be moved forward empty and subsequently filled automatically from a roll of sensitized paper.

Abstract: 1,014,476. Read-only stores. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 31, 1963 [Aug. 15, 1962], No. 31301/62. Heading G4A. Where an inductive connection is made between drive conductors 11 and sense conductors 12 by means of patterns of coupling conductors 16 or 17, the effect is enhanced by providing an unbalanced capacitive coupling between the conductors. It is explained that by splitting the coupling conductors diagonally, as shown, the coupling between conductors X and C is greater than that between X and D. The e.m.f. across C and D is therefore increased by this capacitive coupling. Various patterns are shown for various configurations of drive conductors, including a single drive conductor which for a short distance is caused to run parallel to the sense conductors. The patterns 16, 17 can represent the two binary values or two of the ternary values, the zero being represented by absence of a pattern.
