Abstract: An internal combustion engine includes one or more pistons (4), each of which is mounted to reciprocate in a respective cylinder (2) and is pivotably connected to a connecting rod (6) which is connected to a respective crank on a crankshaft (7). The connecting rod (6) is pivotably connected to one end of an elongate link (14), which is pivotably connected to the associated crank at a point intermediate its ends and whose other end constitutes a rod (18) which is restrained by a mounting (20, 24) such that it may pivot about a pivotal axis parallel to the axis of the crankshaft. The mounting includes a first movable mounting member (20) and a second movable mounting member (24). The first mounting member (20) is connected to the rod (18) by a connection which permits only relative sliding movement in the direction of the length of the rod and is pivotally connected to the second mounting member (24) to pivot with respect thereto about the said pivotal axis.

Abstract: There is provided an electric cable insert for removably electrically connecting a cable having multiple conductors to a mating receptacle wherein the number and configuration of the cable conductors may be different from those of the sockets of the mating receptacle. The insert includes a housing open on one end to an internal cavity and having a plurality of orifices in the other end. The cable conductors connect to one side of a circuit card within the housing which conductively transitions from the number and configuration of the cable conductors to the number and configuration of the sockets of the mating receptacle. Receptacle pins extend from the opposite side of the circuit card through respective orifices in the housing for connecting to respective sockets in the mating receptacle. A compressed sealing gland disposed within the housing adjacent the circuit card provides the insert with an energized compression seal from the environment.

Abstract: A conductive rope-like lead-in cable connects a seismic streamer to a towing vessel. The lead-in cable comprises a first electrical conductor at the center core of the cable for carrying a first polarity of power to the streamer for providing tensile strength to the load-in cable. A first layer of insulation surrounds the first electrical conductor. A second electrical conductor for a second polarity of power to the streamer surrounds the first layer of insulation. A second layer of insulation surrounds the second electrical conductor. A layer of seismic data conductors surrounds the second layer of insulation. A third layer of insulation surrounds the layer of seismic data conductors. A metallic protective layer surrounds the third layer of insulation. Steel is effectively and efficiently used both to provide tensile strength and for electrical power conduction.
