  • Patent number: 5174814
    Abstract: Retractable marker pens and ink formulations for marker pens. The ink formulation has particular utility as a fluorescent ink for highlighting text or print. The formulation reduces the rate of ink evaporation from conventional felt, fiber or plastic marker tips. This property makes the ink especially suitable for use in retractable marker pens which do not normally employ a separate tight fitting cap or a lint guard to protect the marker tip from ink evaporation when the marker pen is in non-use. The ink formulation exhibits excellent flow characteristics to conventional felt, fiber or plastic marker tips over a wide range in tip widths. The ink does not leak from the tip and does not penetrate paper so as to obscure text or printed material on the opposite side of the paper. The ink is composed of a fluorescent dye, selected from methine, xanthene and anthraquinone dyes dissolved in a multicomponent solvent system.

  • Patent number: 5042558
    Abstract: A fastener dispensing needle is manufactured by a machining process which includes bending a metal tube to assist in obtaining an important configuration for the tip of the needle. A flared portion of the needle tip determines the diameter of the hole made through the material of the object being penetrated by the needle. This flared portion is sized to make a hole at least large enough to overlap with the diameter of the central bore through the needle. This minimizes unnecessary stresses on the fastener as it is ejected from the needle, thus resulting in fewer undesired breakages of the fasteners. In addition, the area of the needle where the central bore and longitudinal groove merge into the tip portion of the needle is configured to minimize cutting action on the filament of the fastener, again resulting in fewer undesired breakages.
