  • Patent number: 5204228
    Abstract: A method of processing a silver halide color photographic light-sensitive material having a silver halide emulsion layer containing silver halie grains having a silver chloride content of not less than 80 mol %, wherein said silver halide color photographic material, after being subjected to color-development, is continuously processed with a bleaching solution comprising at least one of ferric complex salts of compounds represented by the following formula [A] or [B]: ##STR1##

  • Patent number: 5119615
    Abstract: A plurality of clamps arranged in equally spaced relation on an endless track are intermittently advanced at a pitch equal to the distance of each two adjacent clamps. A switch reactive only to the passage of a sufficiently heavy or filled bag which has been filled with an article is disposed downstream of a filling station, one of the stop positions for clamps. When the passage of a bag is not responded by switch, that is, when an empty or unfilled bag has passed near the switch, the particular clamp by which the empty bag is held is caused to pass through the final stop position and, in turn, through the first stop position before it can again reach the filling station, with the empty bag being held by the clamp all the while.

  • Patent number: 4155435
    Abstract: A device for receiving power from a rigid conductor extending in the direction of advance to an electrically driven, rail vehicle, which comprises current collecting members independently supported on a base through elastic members having a low spring constant, as far as possible, within the working ranges. The current collecting member has a higher predetermined vertical level than the average static height of the rigid conductor so as to be displaced back to the average static level of the rigid conductor. The current collecting member is maintained in a resilient condition during operation so that it is responsive to any sudden changes in pressure and thus prevent separation from the rigid conductor.
