Title: Automatic machine for photographs
IPC: G03B17/53
Filed: 1928-09-19
Abstract: 298,602. Siemens & Halske Akt.-Ges. Oct.. 12, 1927, [Convention date]. Automatic apparatus. - In an automatic photographic machine, the photographs are carried forward through the treatment baths &c. by a chain &c. running the length of the baths, the grippers being arranged to turn the photographs into and out of the various baths perpendicularly to the direction of the chain. Each gripper 6 consists of two clamping members f, Fig. 3, held together by springs g which are connected by a hinge h to the chain 5. The gripper receives the exposed paper &c. 21 from the receiving box 2 comprising plates a, b fastened to a carrier c having a tapered foot d which separates the members f to allow the paper &c. to enter the gripper. The gripper is then carried by the chain to the developing bath 7 where it is turned by a suitable guide through 180 degrees about its hinge to immerse the paper in the bath, the sensitized surface being the first to enter the liquid. The paper is drawn edgewise through the bath, the chain being passed over guide rollers R1, R2, R3, and on reaching the end of the bath it is turned up by a guide 11 until it is nearly horizontal. The paper is then carried to the clearing bath 14 but before, reaching this bath it is turned downwards and washed by sprinklers 23. It is then turned into the horizontal position just before reaching the bath 14 into which it is turned downwards and through which it passes edgewise. In a similar way the paper is passed through a. reversing bath 16 and a toning bath 17, and is washed by sprinklers 23 after leaving each bath. It is then passed through drying apparatus 18 td a delivery box 19 over which the gripper is opened by a, tapered plate 20. The gripper is then turned through 180 degrees by a guide plate 22 so that it becomes upwardly directed to receive another paper. Owing to the paper being drawn edgewise through the arious baths, these baths can be made very narrow except at their ends where the paper enters and leaves, thus reducing the quantity of liquid required for renewing them.

Abstract: 1459644 Making grain-oriented steel sheet NIPPON STEEL CORP 18 June 1974 [18 June 1973] 27132/74 Heading B3A [Also in Division C7] A method of making grain-oriented steel sheet or strip comprises hot rolling silicon steel material containing 2À5-4% Si, 0À085% max. C and 0À010-0À065% acid soluble Al, annealing the hot rolled steel at 950-1200‹ C., then either immediately or after an initial cooling rapidly cooling it to precipitate AlN, cold rolling the steel to a reduction of 81-95% in a series of passes, the steel being held at 100-350‹ C. for at least one minute between two of the cold rolling passes, decarburization annealing and final annealing. The starting material for the method comprises a conventionally made ingot, which is hot rolled into strip. The strip is annealed for 30 seconds to 30 minutes at 950-1200‹ C. and preferably allowed to cool to 750-950‹ C. prior to cooling down to 400‹ C. in 2-200 seconds. The preferred temperature range for the ageing treatment between cold rolling passes is 100- 200‹ C., at which the strip should be held for 5 minutes to 5 hours. The ageing must be performed during the cold rolling process if optimum magnetic properties are to be obtained. The required temperature may be obtained by controlled cooling of the rolls or by feeding the strip to a heat-retaining or a heating device. Decarburization annealing is performed at 700-900‹ C. for 30 seconds to 30 minutes to lower the carbon content to 0À005% or less. Final annealing is performed at a minimum temperature of 1000‹ C. for at least 5 hours in an atmosphere of H 2  or N 2  to allow the secondary recrystallization grains of {110}<001> orientation to develop satisfactorily.
