<BODY> <div> General Thermodynamics Offers Free Literature On 300-A BMEP Balancer General Thermodynamics Corpo- ration of Plymouth, Mass., has pub- lished free literature on the model 300-A BMEP Balancer that is used to equalize the cylinder load of any multicylinder internal combustion engine equipped with individual fuel adjustments. The publication, which contains a photograph of the balancer, de- scribes it as being designed to fit the standard indicator valve. It is quick- ly connected and sealed with slight- ly more than hand tight torque. When the indicator valve is opened, the pressure gauge will come to a reading, gently. The pointer is steady and will stay fixed as long as the cylinder load isn't changed. Keeping the engine load constant, readings are taken for each cylinder, then fuel adjustments are made either up or down until all cylinders yield the same pressure reading. Each cylinder is then delivering equal power. Along with the application, the operation and construction of the BMEP Balancer are also discussed, and some of its main characteristics are listed, such as: steady, accurate, repeatable, reliable, requires no maintenance, fits standard indica- tor valve, and easy to use.

This need has caused equipment manufacturers to search for better pumps and fire monitors for op- timum placement of water at plat- form fire locations. In tests of the effects of pump pressures and fire nozzle shapes on water trajectories, a Worthington team compared various combina- tions of nozzles (with cone and pa- rallel configurations), monitors, and pumps. A report on the result of these tests has recently been pub- lished in an issue of "Power & Fluids" (Vol. 10/No. 2) by Wor- thington Division, McGraw-Edison Company, of New Jersey. The first part of the 20-page color publication is devoted to an article titled "Fire-fighting monitor re- search aids offshore oil field safety," by Anthony Lukes, London area sales manager of Worthington In- ternational Inc., and Victor Car- rell, an engineer at Worthington- Simpson Ltd., England. The article points out that in the middle 1970s, when the petroleum industry began developing specialized craft for off- shore fire-fighting duties, followed by radically different seagoing units such as the emergency support ves- sel (ESV) IOLAIR, built for British Petroleum, it became apparent at the preliminary design stage that there was a lack of firm and reliable data on which to base the design of fire-fighting equipment to meet their needs. For this reason, Wor- thington-Simpson and its associates decided to conduct tests with full- size equipment to accurately define the state-of-the-art and to advance it if possible. These tests are said to have produced findings that prom- ise more effective marine fire-fight- ing devices and may contribute to onshore technology as well. The article, which is illustrated with photos, profile of rig layout, etc., lists the test objectives and dis- cusses the designing of the test rig, test nozzles, pressure measure- ments, measuring jet trajectory, test procedure, total number of tests carried out, nozzle shapes, trajecto- ries at different flow rates and pres- sures, pressure drops and velocity through the monitor, and conclu- sions drawn from the tests. The last part of the "Power & Fluids" issue presents Part I of a paper by Igor Karassik, chief consulting engineer for Worthing- ton, titled "Centrifugal pump appli- cation . . . the next milestone (VFD)." The paper discusses the advantages and benefits of variable- frequency drives (VFD), long-range developments, and conclusions. The cover of the pamphlet fea- tures a striking photograph of the unusual vessel ESV IOLAIR, de- scribed as the world's largest fire engine, which can provide a number of emergency services for North Sea oil production platforms.
