Vulcan Hydraulic Gearing on Metorship Kota Agocng cubic meters against a head of 30 meters, supplies the sea-water re- quired for circulating through the cooler, the sanitary pump acting as a reserve. As in normal operation the load is to be equally divided between both main engines, the control gear is coupled together in such a manner, that both engines may be controlled from one central control point, this being located at the starboard engine controls. Since, as is well known, all opera- tions for reversing, starting and speed regulation on the Fijenoord M. A. N. diesel engines, are accomplished by means of a single hand-wheel, a sim- ple solution has been found therefor, by connecting together the shafts of the control wheels by means of bevel gears and intermediate shafts. The controls for the reversing valves for forward and reverse are also con- nected together by means of rods. In case only one engine is functioning, the above mentioned connections may be easily disconnected. Due to the fact that when the coup- lings are empty there is no connec- tion between the two engines nor with the propeller shaft, it was necessary to provide the engines as well as the propeller shaft with a turning gear. When any one of the three is in mesh with the turning gear, the controlling gear is locked’ out automatically. The auxiliary engines consist of three diesel driven dynamos, two of which are for normal use and one for harbor purposes. The two large dynamos are driven by three-cylinder four-stroke Fijenoord-M. A. N. en- gines each rated at 300 brake horse- power and having a speed of 250 rey- olutions per minute. The diameter of the cylinder is 1634 inches and stroke 235, inches. The dynamos have an output of 200 kilowatts apiece. One machine is able to supply all the cur- 32 rent necessary at sea and when han- dling cargo. These engines are ar- ranged to drive fresh water cooling pumps for warming the main engine jackets in cold weather. Aft of these dynamos is an M. A. N. compressorless four-stroke engine for harbor use. This motor is coupled to a 50 kilowatt dynamo, has four cyl- inders and is rated at 75 brake horse- power at 275 revolutions per minute. Two auxiliary air compressors are pro- vided. One has a capacity of 550 cubic meters of free air per minute compressed to 75 kilograms per square centimeter while the other fitted for emergency purposes only has a capac- ity of 15 cubic meters of air com- pressed to 75 kilograms per square centimeter. The refrigerating com- pressor is driven by an 11 to 14 horse- power motor running at between 150 and 180 revolutions per minute. This apparatus is of the ammonia type. The deck machinery is entirely electrical and comprises 11 cargo winches each with a capacity of five One of the Vulcan Coupling Impellers on M. S.

There are two . electric cranes on the boat deck each with a lifting capacity of two tong The anchor windlass is located for: ward with the motor below. The mo. tor drives a horizontal worm shaft which operates a vertical shaft Car- ried up to the windlass. This motor is of the compound wound type and is rated at 48 horsepower with the max. imum speed being 720 revolutions per minute on a half-hour rating. While being a standard cargo ves. sel as regards the design of the hull, the Kora Acoene is of: particular ip. terest from a machinery installation point of view. It is understood that the intention of the Rotterdam Lloyd line is to consider the Vulcan geareg drive with a view to its application to passenger ships due to its saving of overhead space. During the trial runs of this yes. sel very satisfactory results were no- ticed; the engines performed efficient. ly, the gearing was reasonably silent, vibration limited and the maneuver- ing ability notable. Distance Tables Are Ready Tho coast and geodetic survey, de- partment of commerce, Washington, recently issued a publication on Dis- tances Between United States Ports which should prove of value to those interested in the factors affecting transportation by water. The publica- tion gives tables from which the shortest distance can be obtained be- tween practically any two ports of the United States, its territories, and its possessions. The tables give dis- tances between ports on the Atlantic, Gulf, and Pacific coasts, on the At- lantic coast inside routes, on the Hud- son, Mississippi, and Ohio.rivers, on the Great Lakes, in the Virgin is- lands, Porto Rico, Philippine, and Hawaiian islands, and between United States and a few foreign ports. A table showing time required to run various distances at different speeds is also included in the publication. Prepare New Light Lists The lighthouse service, of the de- partment of commerce is now prepar- ing new editions of its light lists. The reprinting of these light lists in- volves the verification of several thou- sand items. They are divided into three main sections and will be cor- rected to the following dates: Atlantic and Gulf coasts to Dec. 15; Pacific coast to Jan. 1; Great Lakes to March 1. The first two lists will be ready early in 1931, and that for the Great Lakes with the opening of navigation in the spring. The new Pennsylvania railroad ter- minal at Jersey City, N. J., known as the “rail-to-keel” terminal, was formally opened on Jan. 6.
