The flexible member has at least one elongated tab extending tangentially and radially about the circumferential edge of the member and which. when wrapped about the digit is partially secured to both the circumferential edge of the member and the skin of the digit to which the apparatus is to be secured whereby allowing the protective apparatus to be releasably secured in position on the finger/toe tip of a person.

Abstract: A lock assembly for a railcar gate assembly including a frame defining a discharge opening, a gate mounted on said frame for sliding movements along a predetermined path of travel between open and closed positions and relative to the discharge opening, and a drive mechanism for moving and movable with the gate between the open and closed positions thereof. The lock assembly includes a stop mounted for movement between locking and unlocking conditions. At least a portion of the stop extends into the path of travel of the gate when in the locking condition thereby operably preventing inadvertent movement of the gate from the closed position toward the open position. The stop is selectively movable into the unlocking condition whereby allowing the gate to be moved toward the open position from the closed position. The lock assembly further includes a spring biased mechanism for positively maintaining the stop in the unlocking condition until after the gate moves a predetermined distance from the closed position.

Abstract: A cargo container door lock assembly including a resiliently biased door locking member movable between locked and unlocked conditions and adapted to be mounted to an interior surface of a cargo door on a cargo container including a rigid door frame. The door frame defines an opening configured to receive and accommodate a portion of the door locking member when the cargo container door is moved into a closed position. The opening in the door frame has a closed margin which interengages with the door locking member, when the cargo door is moved to a closed position, to prevent movement of the cargo door toward an open position. With the cargo container door in the closed position, the resiliently biased door locking member is accessible to being moved into an unlocked condition, thus allowing said cargo door to be moved to the open position, only from an underside of the door locking member.

Abstract: A compression spring created from a preform made from an elastomer which is free of spring-like characteristics and has a ratio of plastic strain to elastic strain greater than 1.5 to 1.
