Abstract: A self-locking wire seal includes a body in which one end of a wire is fixedly secured. The free end of the wire can be inserted through the hasp of a lock. The free end of the wire is then inserted through a channel in the body of the seal. The wire contacts a locking mechanism which automatically prevents the retraction of the wire out of the channel defined in the body. The locking mechanism may comprise a spring which engages notches defined on the wire. The notches may be defined by using a concentrically laid spiral wound wire. The spring flexes out of the way of these notches when inserted, but grips the wire when attempts are made to retract the wire from the body of the seal.

Abstract: A machine for cutting damaged ends off of rolls of wound sheet material includes a saw that moves in a circular motion about the circumference of one end of the roll of material. The circular motion of the saw is coupled with a movement of the saw radially inward toward the center of the axis of the circular movement. The roll is thereby cut in ever increasing depths about its circumference. The machine is mounted on a portable hydraulic lift and controlled by a remote controller positioned a safe distance away from the saw. The machine and the roll of material can be more easily aligned through the use of an alignment track.

Abstract: A cable lock includes a security insert to help prevent tampering with the internal components of the cable lock. The security insert may include a pair of side panels oriented generally parallel to each other and an end panel oriented generally perpendicular to the side panels. The security insert fits between an inner and outer member which are both made of relatively soft metal, such as aluminum or zinc casting. The security insert is made of a harder material, such as steel, which is resistant to drilling. The security insert surrounds a locking mechanism that may include a disc positioned on an angled incline.

Abstract: An improved locking device which has a body member with a cable which has one end attached to the body member and a second end of the cable which can be inserted into the body member in a first direction but which cannot be withdrawn in a second direction. An improved spiral spring biases a disc that rides on a ramp into engagement with the second end of the cable so as to lock it so it cannot be withdrawn from the body member, the coil spring provides a simple and efficient biasing device.

Abstract: A cable locking and sealing device which has an attached cable and the free end of the cable can be passed through a member to lock it. Then the free end of the cable is passed down through an opening in the body of the locking and sealing device in which there is a spring biased conical-shaped member that carries a ball mounted in a transverse opening. The ball rides on an inclined conical surface and engages and locks the cable when an attempt is made to withdraw it from the locking device in a direction opposite to the inserted direction.

Abstract: Cable locking and sealing device which has a body member to which one end of a cable can be attached with the other end free to pass through a hasp or other device to be sealed or locked and in which the free end can then be inserted into the body member and can be freely moved in a first direction into the body member but which is clamped so that it cannot be removed from the body member in a second direction. Within the body member there is provided an inclined ramp at a small angle formed with a plurality of gear teeth and a locking gear formed with gear teeth which mate with the gear teeth on the rack and is movable along the ramp so as to lock the second end of the cable to the body member when force is exerted on it to remove it from the body member.
