Abstract: A coupling assembly for coupling high pressure air flow produced by ground equipment to a start nipple having an interior diameter of a particular dimension contained on an aircraft, including, a housing member having an enlarged section with an interior diameter of a dimension greater than the particular diameter of the start nipple and with the housing member having one end adapted for coupling to the ground equipment, a pair of vane members forming a clam shell type restrictor valve located within the enlarged section of the housing member and rotating around positions at the sides of the housing member and with the vane members in a closed position blocking the high pressure air flow through the coupling assembly and with the vane members in an open position forming a continuation of the interior diameter of the start nipple to form a continuous air flow path through the coupling assembly and start nipple, and a locking assembly coupled to the other end of the housing member and adapted for coupling to an

Abstract: A clamp device including a resilient lining and with the clamp including an elongated member having a loop portion, and a resilient lining formed by a strip of resilient material of a sufficient length to extend along the elongated member in the loop portion and of a sufficient width to extend across the elongated member in the loop portion. The strip of resilient material is formed on one side of the strip for attachment to the loop portion of the elongated member so as to have the strip form a resilient lining on the inside of the loop portion of the elongated member. The strip of resilient material includes gripping means formed on the other side of the strip and with the gripping means formed as a plurality of needle-like protruberences extending along the length and across the width of the strip from the other side of the strip and toward the center of the loop portion of the elongated member.
