The invention relates to a method for preparing a relief printing plate from a printing plate precursor wherein at least an end of the precursor is attached to a leader forming a composite printing form precursor that securely mounts the precursor in a treatment processor. The present method advantageously allows for all or substantially all of the area of the precursor to be utilized for forming the relief surface suitable for printing.

A method and apparatus of securing and tensioning a printing form in an apparatus having a rotatable drum includes securing a first portion of the printing form to a first means for receiving that is coupled to a surface of the drum, and securing a second portion of the printing form to a second means for receiving that is disposed on a rotatable member that extends over a portion of the drum. The rotatable member is rotated so that the circumferential distance between the first receiving means and the second receiving means is about the same as a length of the printing form. A rotary torque means is coupled to the rotatable member to apply a substantially constant torque on the member and tension the printing form about the surface of the drum. The rotary torque means adjusts torque on the member which adjusts tension on the printing form.

Method and apparatus for tensioning a printing form

A method and apparatus of securing and tensioning a printing form in an apparatus having a rotatable drum, comprising positioning a first portion of the printing form over a first set of pins that are coupled to a surface of the drum. The first portion of the printing form is then stamped onto the first set of pins thereby securing the first portion of the printing form to the drum. A rotatable member having a second set of pins is rotated so that the circumferential distance between the first set of pins and the second set of pins, is about equal to the length of the printing form. The drum is rotated until a second portion of the printing form is positioned above the second set of pins. The second portion of the printing form is then stamped onto the second set of pins.

Methods and apparati for screening compounds for agricultural activity has now been developed which employ e.g., intact plants grown in microtiter plates on very small amounts of plant growth media containing a test compound. In comparison to the standard greenhouse screen, the microscreen requires vastly less space, labor, and test compound. However, unlike in vitro screens, responses of intact plants are assayed. Using the microscreen, high-throughput screening of test compounds can be accomplished using whole plant responses as the assay.

A multiple dosage feeder for a cage is provided. The multiple dosage feeder includes a frame having a cage-interior side, a food holding member rotatably mounted on the frame, and a food presentation member disposed on the cage-interior side of the frame. The food holding member holds a plurality of measured dosages of food or other substances, and at least a portion of the food holding member extends to the cage-interior side of the frame. The food presentation member permits access to a single dosage of the plurality of dosages by an animal within the cage. At least a portion of the food holding member is rotatable within the food presentation member so as to expose the single dosage of the plurality of dosages, while the food presentation member prevents access to any remaining dosages on the cage-interior side of the frame.
