Abstract: A method of forming a container from bi-axially orientable plastics material and having an integral handle with the steps of forming a preform having a neck portion and an expandable portion below the neck portion, with the neck portion including a locating ring above the expandable portion and a handle molded to the non expandable at one end and molded to the expandle portion at the other end. Where the molded-in handle is the approximate length of the handle of the finished container. The unblown preform of orientable plastics is inserted into a blow molder and thereafter stretched by a stretch rod. During the stretch process the handle on the preform unbends rather than stretching to form the approximate shape of the handle in the finished container. The blow mold then closes on the stretched preform thus capturing the handle. Blow gas is then injected into the interior.

Abstract: A container with a recessed handle. A middle portion of a container is positioned between a first and second portion wherein the middle portion has a recessed access area. A handle is positioned in the recessed access area wherein the handle is planar with an exterior of the container.

Abstract: A preform or parison for manufacturing a container having a large interior diameter body and small interior diameter opening is prepared by molding the preform in two parts, a body having a generally cylindrical sidewall with one open end and one closed end, and a preform end having a diameter sized to mate with the sidewall and an opening therein for accessing the interior of the preform, and then joining the preform body and preform end to form a complete preform having an internal diameter larger than the diameter of the opening. The preform so formed is then used in a conventional blow molding process to produce a container having a large internal diameter and a narrow access opening.

Abstract: An answer document or form, on which the user darkens certain discrete response areas with a graphite or lead pencil to denote his selected choices or data entries, has a bias bar printed across one end with the same color ink used in printing the remainder of the document. When the document is read by the optical scanner, the light passing through the translucent paper also passes through the printed bias bar. Analog voltage signals are obtained from each of the photocells in the optical scanner and these signals are capacitively stored, then converted to digital values. The digital values are averaged and the individual digital values for each photocell are compared with the computed average to check for bad cells. If a poor photocell response persists for a predetermined number of answer documents, the entire scanning operation is stopped.
