Cairns Named Operations General Manager For Cross And Southern Ocean Ian Cairns has been appointed general manager of operations for Cross Marine, Inc. and Southern Ocean Corporation of Belle Chasse, La. The latter company will own and operate a 500-ton-capacity der- rick barge, the Southern Hercules, now being outfitted by Boland Ma- rine and Manufacturing, Inc. of New Orleans. The barge will be used for multi- ple assignments including oilfield construction, maintenance, repair, and salvage. It will also be employed for river and harbor work such as stevedoring and shipyard loadouts. Where practical, it will operate in conjunction with Cross Marine's self-elevating workboats that can be fitted to accommodate up to 40-per- son work crews. According to Mr. Cairns, this combination will enable the two companies to offer services usually reserved for large derrick barges but at a substantial reduction in cost. No Lubrication Required For Falk 'Torus' Couplings— Literature Available The Falk Corporation of Milwau- kee, Wis., reports that its Torus Type WA couplings with all-steel hubs never need lubrication. And no maintenance except for routine in- spections. The couplings also fea- ture high torsional flexibility and easy installation. Falk's unique design—utilizing a non-lubricated, soft and resilient element of U-shaped multi-ply ny- lon and rubber—provides the tor- sional flexibility to absorb reason- able amounts of shock loads, vibra- tion, misalignment and end float. The larger the coupling, the greater the number of plies that are used. The tough, rubber-nylon element is not affected by dust, dirt or ambient temperatures from —40°F to + 150°F ( —40°C to +66°C). Hubs are available in a wide choice of popular bores (Vs-inch to 8 inches), or bored for taper bushings. Long steel hubs are offered for mill motors, other tapered shafts, and for overhung hubs. Torus couplings are stocked in 15 different sizes to match light to severe duty applications, and are rated for 540 to 141,800 lb./in. torque and .86 to 225.0 hp per 100 rpm. Falk also offers fluid, "Steel- flex" and gear-type couplings. The Falk Corporation, Milwau- kee-based subsidiary of Sundstrand Corporation, is a major manufactur- er of industrial power machinery, including gear drives, couplings and backstops.
