Abstract: 903,861. Sensing record-cards. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 27, 1961 [March 3, 1960], No. 7069/61. Class 106 (1). In a card-sensing machine provision is made to sense cards the hole spacing of which differs from the card feed steps of the machine by moving the sensing pins forwards or backwards in the direction of movement of the card during the sensing of the card so that at each hole position the sensing pins are aligned with the holes. The sensing pins 26, 27 are mounted on a carriage 2 which can reciprocate in the direction of the card movement and its position is controlled by two cams 3 and 4 having forward and backward followers 13, 14. The cams rotate once during the passage of a card through the machine. The sensing pins which are normally held raised by levers 24, 39 are lowered to perform the sensing operation. When a hole is present they allow a contact blade 35 to engage a contact 36. The pins 26 are for sensing additional data rows between the normal rows and they are disabled by rotating lever 23. This is achieved by a knob 15 which rotates a cam 17 to rotate a lever 19 about its pivot 20. The plate 21 bears down on follower roller 22 to rotate the lever 23 while still permitting reciprocation of the carriage.

Filed: 1929-03-06
Abstract: 329,066. Manufacture de Machines Auxiliaires pour l'ElectricitÚ et l'Industrie, and Texier, D. A. L. March 6, 1929. Waterproofing; proofing processes and compositions; wood, treating with liquids and gases.- After articles of wood, tissue, paper, cardboard, metal, or other material have been impregnated with a solution of a synthetic resin, the solvent is extracted and the resin polymerized by subjecting the articles to a gaseous atmosphere which will absorb the solvent, is condensable at ordinary temperatures and which possesses a high specific heat. The solvent is thereby more readily condensed than when absorbed in an atmosphere of ordinary air, and, owing to the higher specific heat of the gas, the polymerization is effected more quickly at a given temperature when using such gas than is the case when using ordinary air. In particular, dry steam is used when an alcoholic solution of phenolformaldehyde condensation product is the impregnating agent. An apparatus for carrying out the process comprises a chamber 1 in which the impregnated articles are placed, a water or air-cooled condenser 7, a blower 3 and a heater 2 having an inlet 15 for steam. The valve 10 is opened, valve 11 closed, and, after air has been circulated for some time, steam is admitted to the circuit through the valve 15.
