    Abstract: A tool includes first and second elongated members, each member having a handle portion at one end and a jaw portion at an opposite end. Intermediate portions of the members are movably coupled to one another. Movement of the handle portions opens and closes the jaw portions. Each jaw portion includes a gripping surface configured to grip a workpiece. A pair of blade members are rigidly secured to the jaw portions, each blade member having a cutting edge.

    Abstract: A D-ring of metal wire is specially shaped to accept and retain a special grommet of a hard, wear-resistant polymeric material. The D-ring has a base leg, a pair of side legs joined to opposite ends of the base leg and converging toward each other from junctures with the base leg, and a substantially arcuate head joined to the side legs at junctures forming a neck opening that is constricted relative to a head opening defined within the head. The grommet is received within the head opening and neck opening of the D-ring and has a hole adapted to receive a hook and a peripheral groove that is in captured engagement with the head of the D-ring and with the junctures of the head and the leg portions. Portions of the groove located at the neck opening of the D-ring are deepened relative to adjacent portions of the groove within the head opening so as to retain the grommet while enabling the grommet to be pressed endwise through the neck opening and into the head opening of the D-ring.

    Abstract: A portable door securement device is provided having a member extending from a first end engaged to a doorknob of a door to a second end engaged with a floor adjacent the door, to prevent opening of the door in a direction toward the engaged member. A slot at a first end of the member engages around a stem of the door handle thereby preventing disengagement of the member from the door, and preventing opening of the door.

    Abstract: A method for repairing defects in a substrate comprising the steps of placing a consumable filler slug in contact with the substrate in the vicinity of the defect; placing at least one electrically conductive cover sheet in contact with a portion of the consumable filler slug; bringing a first electrode and a second electrode in contact with the at least one cover sheet and applying a force; and transmitting electrical current between the electrodes, thereby resistively heating the at least one cover sheet and conductively heating the consumable slug and a portion of the substrate resulting in coalescence in a substantially liquid pool that fills the defect. The pool is then cooled to solidification under pressure. Alternative embodiments eliminate the need for the conductive cover sheet(s) by utilizing electrodes having increased electrical and thermal resistance. The consumable slug may be formed as a single unit or multiple sections, and may incorporate sacrificial retainers.

    Abstract translation: 一种用于修复衬底中的缺陷的方法，包括以下步骤：在所述缺陷附近放置消耗性填料块与所述衬底接触; 将至少一个导电覆盖片放置成与所述可消耗填料块的一部分接触; 使第一电极和第二电极与所述至少一个覆盖片接触并施加力; 并且在电极之间传输电流，从而电阻加热至少一个覆盖片，并导电地加热消耗的块状物和一部分衬底，从而在充满缺陷的基本液体池中聚结。 然后将该池在压力下冷却至凝固。 替代实施例通过利用具有增加的电阻和耐热性的电极来消除对导电覆盖片的需要。 消耗性块塞可以形成为单个单元或多个部分，并且可以包括牺牲保持器。
