Abstract: An apparatus for the development of an electrostatic latent image in a magnification-variable copier which is capable of preventing the development of black frames on the outer circumference of copying portion when the reproduction is to be performed on a reduced scale. For this purpose, the apparatus includes a developing electrode which is divided into a plurality of units, such that a proper biasing potential is applied to the copying portion, and a high biasing potential is applied to other portions, whereby the developing is not effected for the unnecessary portions.

Abstract: Hot melt adhesive is applied to a moving substrate in a pattern including at least two lines which extend transversely to one another, by conveying the substrate past a nozzle orifice through which a first line of molten adhesive is applied, as by extrusion, to the substrate parallel to the direction of substrate movement and, while continuing to move the substrate in the same direction, projecting another portion of the molten hot melt adhesive onto the substrate as a burst in the form of a flat sheet issuing from a fan spray orifice, this orifice being oriented so that the sheet is projected transversely to the direction of substrate movement, and terminating the burst so rapidly that the adhesive so projected is deposited on the moving substrate in the form of a line having a length in the crosswise direction that is several times its width.

Abstract: Apparatus for continuous heat transfer of ink images onto outer surfaces of continuously moving generally cylindrical members from a length of continuously moving heat transfer sheet material having thereon a series of uniformly spaced heat transferable ink images.

Abstract: An apparatus for applying a sealant or the like to a selected area of a container. The apparatus includes a nozzle for dispensing the sealant onto the selected area of the container. The nozzle includes a first portion which is adapted for mounting the nozzle to a source of sealant. The nozzle also includes a second portion which has a free end with a discharge opening onto the exterior surface of the free end. A first flow passage communicates with a source of sealant and provides flow communication between the source and the discharge passage having the discharge opening. The discharge passage is elongate having a width greater than the height of the passage.

Abstract: A method and apparatus for inspecting and marking flawed sheet material is disclosed. Sheet material is moved from a supply along its length through a path to a cutter. The sheet material is visually inspected as it moves along its path, and a temporary electrically conductive mark is applied to the moving material at a predetermined distance away from any flaw that appears in the sheet material. The temporary mark is electrically detected at a position along the path the same predetermined distance away from the cutter as the flaw moves into the cutter, and as the last portion of the segment to be cut from the sheet material moves to the cutter, the sheet material is marked with a permanent mark. The sheet material is then cut and folded, and the permanent mark is located at a predetermined position in the folded segment of sheet material, no matter at what location in the segment of the sheet material the flaw appears.
