Practical LEGO Technics: Bring Your LEGO Creations to Life

You realize you could create remarkable issues with LEGO, yet were you aware you can make autos that roll and version plans that come with touchdown apparatus and flaps that really expand and retract? it's also possible to make sensible robots with out moving into Mindstorms and programming. In sensible LEGO Technics, Mark Rollins indicates you ways to take advantage of LEGO and tool services parts like vehicles and distant controls to create motorized autos, all terrain cars, automobile guidance, development gear resembling cranes and forklifts, airplanes.

Sample text

An installation check of the runout of the combined generator and turbine shafts should be required, especially where com bined align men t h a s not been performed a t the factory. 2. As indicated therein, the methods applicable depend upon the type of thrust bearing furnished with the generator. If the rotation check by method 1 is used, it shall be performed during the erection of the generator t o avoid subsequent disassembly of the machine. 11 Shaft-Plumb and Straightness Check. This is a plumb-wire check of the straightness and plumbness of the combined generator and turbine shafts.

After the unit has been balanced and has had a dry-out run, it should be operated a t rated speed and its voltage built up slowly by applying excitation. The terminal voltage and field current should be recorded and compared with the generator manufacturer’s calculated no-load saturation curve. 11. 2 Connection to P o w e r System. Before connecting the generator t o the power system, the phase sequence of the generator and the connections to the synchroscope should be checked and, if they are correct, the generator leads can be connected permanently.

And if you're a utility engineer, manager, or consultant, you'll need to know what the new Code covers. We offer two intensive training programs to help you: *A thoroughly updated 3-day training program that covers the development and application of the Code. *A new 4-day training program that covers the same material as our 3-day program ... plus a special section on work rules. Special team discounts a r e available. IEEE-sponsored training programs may also be brought to your plant. For details, write to the IEEE Manager of Standards Training Programs, 445 Hoes Lane, PO Box 1331, Piscataway, NJ 08855-1331 USA.
