Patent number: 5546855Abstract: A bale tying apparatus for use with a baling press distinguished from the prior art mechanisms in that the articulated arms which shape wire ties about a bale also incorporate elements on the ends thereof to effect the tying of the wires without engagement of the wires with positioning surfaces in the follow block of the press. Thus the tying function is made more reliable and is independent of the follow block precise positioning. A wire loop on at least one end of the wire tie remains in contact with the arm mechanism until the wire knot is made up. The apparatus may use wire loop holding devices at the ends of both arms or may use a housing carried on the end of one arm with an opening for insertion of the other end by the other arm.Type: GrantFiled: June 30, 1995Date of Patent: August 20, 1996Assignee: Lummus CorporationInventors: Donald W.

Patent number: 4736071Abstract: The long term water intrusion resistance of cable splice systems that use a gelable encapsulant that is pressurized prior to geletion can be improved by providing pressurization means that maintain the pressure on the cured encapsulant above a given pressure p.sub.2 >p.sub.o, where p.sub.o is the ambient pressure. Absent such pressurization means, the pressure on the encapsulant typically decreases with time due to creep or relaxation of nominally rigid components, e.g., a polymeric closure around the encapsulated splice, or varies due to differential thermal contraction. The pressurization means comprises one or more energy storage elements, e.g., an elastic member such as a spring, or a volume of compressed gas.Type: GrantFiled: June 3, 1987Date of Patent: April 5, 1988Assignee: American Telephone and Telegraph Company, AT&T Bell LaboratoriesInventors: James B.
