Patent number: 9574688Abstract: First and second conduits are joined in a manner to control electrical resistance of a conduit circuit. A cylindrical section of an adapter is placed onto an end of the first conduit. A part of the cylindrical section is crimped onto the first conduit while a spacing block made of a polymer material having a previously chosen conductivity is positioned around the end of the first conduit and clipped onto the cylindrical section. The crimping locks the spacing block to the adapter and deforms an assembly comprising the clipping pieces of the spacing block and the adapter, so as to immobilize the clipping pieces relative to each other in a direction parallel to an axis of the cylindrical section of the adapter, and such that an exterior surface of the first conduit engages interior surfaces of the spacing block and the adapter.Type: GrantFiled: June 25, 2010Date of Patent: February 21, 2017Assignee: DESIGNED METAL CONNECTIONS, INC.Inventors: Benoit Artaud, Stephane Heraud, Daniel Lecroc

Patent number: 9574694Abstract: An evaporator cuff for use with a pipe freezer apparatus. The evaporator cuff includes a hose connector attached to an evaporator body. The evaporator body has an inner wall configured to engage the outer surface of a pipe, an outer wall spaced apart from the inner wall. A chamber is defined between the inner and outer walls, first and second side walls, and first and second end walls. A plurality of baffles are located in the chamber and arranged to define a series of conduits for creating a flow path through the chamber for refrigerant to flow along. The walls are arranged so as to form a serpentine flow path from the evaporator inlet to the evaporator outlet.Type: GrantFiled: August 11, 2014Date of Patent: February 21, 2017Assignee: Spectronics CorporationInventor: Limin Chen

Patent number: 9574696Abstract: A thrust apparatus for a rod string. The apparatus has a stationary frame, a thrust frame with a rod gripper, two hydraulic cylinders and two rams in fluid communication with the hydraulic cylinders. During low-load operations, the hydraulic cylinders act alone, providing the load to the grippers to pull or push the rod string. When higher loads are required, a check valve is activated, allowing fluid from the hydraulic cylinders to activate the rams. The rams provide additional force to the grippers, and may be activated without mechanical or significant hydraulic changes to the apparatus.Type: GrantFiled: March 12, 2014Date of Patent: February 21, 2017Assignee: Earth Tool Company LLCInventor: Kelvin C.
