General View of Ninth Shipping, Engineering and Machinery Exhibition, Olympia, London. Exhibition at Olympia Marks Progress in Marine Engineering OMING at a time when the C prospects of British shipping and shipbuilding industries are ‘improving, the ninth shipping, engi- neering and machinery exhibition, held :at Olympia, London, Sept. 8 to 24, was of particular interest. This ex- hibition, which takes place in the ‘fall of every alternate year, is or- -ganized by F. N. Bridges and Sons, Ltd., with the patronage and active support of the British Engineers’ as- sociation Inc., the Society of Motor “Manufacturers and Traders, Ltd., The Ship and Boat Builders’ Association, Ltd., and the British Marine Oil En- gine Manufacturers’ association. The honorary president of the ex- ‘hibition for this year was the Duke of Northumberland, president of the Institution of Naval Architects. The number of the exhibits, which was about 280, and their importance, com- pelled the organizers this year to se- lect Olympia, the largest of the ex- ‘hibition halls of London, as the site of the show. The formal opening ‘took place on Sept. 8 and was pre- By Vincent Delport European Manager, Marine Review sided over by the Duke of Northum- berland. During the period of the exhibition, a number of technical societies and associations arranged official visits. Foreign nations were also represented among the exhibitors as well as among the visitors. The exhibits were primarily repre- sentative of shipbuilding, shipping, marine, electrical and general engi- neering, yachts, power boats, engines, etc. and it is proposed to briefly de- scribe that section of the show which pertains particularly to shipping and shipbuilding. A general survey of the exhibition tends to indicate that during the past two years progress has developed especially along the lines of greater security for pas- sengers, economy of fuel, develop- ments in internal combustion engines, and the use of special materials re- sulting in greater strength combined with reduction of weight. MARINE REVIEW—October, 1927 The Parsons Marine Steam Turbine Co. Ltd., Wallsend-on-Tyne, recently fitted high-pressure geared turbine machinery designed for a boiler: pres- sure of 550 pounds per square inch. They exhibited a model embodying the latest arrangements of geared tur- bines for marine work using higher steam pressure and _ temperatures than have been before adopted. There was also a model of an up-to-date marine turbine, complete with thrust, etc. Burmeister and Wain, Copen- hagen, Denmark, showed a single cyl- inder working model of a double act- ing diesel engine, type 8840-D such as will be installed on the Swedish transatlantic passenger liner KUNGS- HOLM now building; this vessel will be fitted with two engines of this type, totalling 16,500 brake horse- power. A working model of a single cylinder single acting diesel engine, long stroke, crosshead type, and a model of a single cylinder single act- ing diesel engine of the trunk type were also shown, together with mod- els of vessels recently built and en- 29
