Se aiarment Used Afloat. Ashore A Protective and Anticorrosive Covering for Marine Use HE problem of. adequately pro- | tecting metal surfaces in marine work has received a great deal of attention because of the severe con- ditions, tending to quick deterioration, this class of work is subjected to. The Thorkote Products Co. Inc., New York, several years ago developed a protec- _ tive covering which has been given the trade name of Thorkote. It is pro- duced in both cement and plastic form and has pure asphalt as a base and it is claimed, fully meets the particu- larly difficult requirements of marine service. Pure asphalt has long been recog- nized and used as the most depend- able, permanent, and reliable protec- tive material for all surfaces affected by water, acid, alkalies and corrosive gases of every nature. But heretofore the only practical means of applying pure asphalt, has been to apply it hot, an inconvenient, costly and not entirely satisfactory method. From time to time attempts have been made to discover some solvent er cut-back which could be used with asphalt so that it might be applied cold. By the very nature of the sol- vents the original properties of the asphalt were invariablly destroyed in these attempts. Practical use of the product known as Thorokote, demonstrating its last- ing properties, indicates that the prob- lem of depositing a pure asphalt coat- ing without heating, without using cut-back and without special equip- ment or highly skilled labor has been solved. It is made in the following manner. Pure asphalt is dispersed in water by a process known as emul- sification and is carried on as fol- lows: A_ given pure asphalt is broken up into minute particles of 1/5000 to 1/10,000 of an inch in diam- eter, in the presence of water and a small percentage of an innert min- eral colloid. This is done by run- ning pure asphalt into especially de- signed machines which break up the asphalt mechanically and keep the small parts separated by the water. When this material is applied, by brush, trowel, or by spraying, the water evaporates and the small par- ticals of unchanged asphalt coalesce. The result is a homogeneous coating of the original pure asphalt with its inherent qualities unimpaired so that the coalesced film has all the elas- ticity and ductility that are proper- ties of the original asphalt of which thé emulsion was originally made. After the film of emulsion has dried out it will not flow, flux or bleed at comparatively high temperatures. The base of this product is asphalt whether in cement or plastic form, and therefore, it has all the protec- tive properties of this substance. It las been said by Madison Cooper, an authority on insulation that, “air- tight protection to the _ insulating substance is the key to permanent F astest Oce an Liners Orderd in Germ any Plans for the addition of two new vessels, larger than the Co- LUMBUS, to the North Atlantic fleet of the North German Lloyd, were recently announced from Bremen. The liners, which are de- scribed as enlarged and improved vessels of the COLUMBUS type, are to have a gross register of 46,000 tons each. They are to be named the BREMEN and the EUROPA, and are to be employed in the Bremen- New York service. They will have a speed of 27% knots which will make them the fastest ships afloat and will en- able them to make the run between New York and Bremen in six days and from New York to the channel ports of Plymouth and Cherbourg in five days. The BRE- MEN is to be built by the Aktien Gesellschaft Weser in Bremen and the EUROPA is to be built by Blohm & Voss, Hamburg. The COLUMBUS, which hus a gross register of 82,354 tons, was built in the Schichan yard, Danzig, in 1922. insulation regardless of the kind of material used—and there is abso- lutely ‘no exception.” This product is therefore, of special value and is becoming widely used as_ protection for the insulation on boilers, tanks, deck steam lines and other insulated parts aboard ship. In one form or the other it may be used as a protective agent against corrosion everywhere on board ship. It is used on the hull, in the holds, the rudders, boilers, decks, inner bottom, brine coils, fresh water tanks, tail shafts, coal bunkers and many other places aboard ship. 76 Marine Section Meets An executive committee meeting of the marine section of the National Safety council was held on Dec. 15, at the offices of the Texas Co., 17 Battery place, New York. The meet- ing was well attended by member companies as well as by representa- tives of other interested steamship lines. The meeting was called to order by W. P. Kain, chairman of the marine section. The marine section is composed of numerous large and small steam- ship operators and allied industries interested in promoting safety at sea on their vessels and who are determined to reduce the large num- ber of avoidable marine accidents to their personnel. Reduction of ac- cidents on board ship is naturally a feature of vital interest to every steamship operator from a human- itarian standpoint as well as good business. Among the speakers at the ex- ecutive committee meeting were: Rob- ert F. Hand, assistant- manager of the marine department, Standard Oil Co. of New Jersey; Alexander Hynd, marine superintendent, Garland Steam- ship Corp. and Arther M. Tode, super- intendent, technical division, marine department of the Texas Co. During the round table discussions which followed a number of members spoke of their experiences in re- ducing accidents, safeguarding of hazardous conditions and methods employed in supervising and educat- ing their seagoing personnel. Full information as to the important work being carried on by the marine sec- tion can be obtained by addressing Arthur M. Tode.. The Texas Co., 17 Battery place, New York city. Launch Liner Augustus The daughter of Premier Mus- solini, Signorina Edda Mussolini, christened the motorship Atcustus when this vessel was launched at Geneoa, Dec. 18. The Augustus will be the largest ship driven by internal combustion engines in the world. In the Augustus, SATURNIA and VULCANIA, Italv will have the three largest diesel ships in ex- istence. Of 33,000 tons, the Augustus is 703 feet long and 82% feet wide. Four propellers are direct driven.
