R.J. Foster and Richard B. Foster have taken their passion for puzzles and created 30 different word searches about girls names that begin with the letters A, B, C, D, and E. These word searches are on thicker, stronger pages than most puzzle books. There is even a blank Notes Page to the left of each puzzle in case you would like to take notes to help solve the puzzle or simply write notes regarding any names that interest you. Search words are forward and backward, up and down, and diagonal.Enjoy!
Linear electric actuators (LEAs) and linear electric generators (LEGs) are widely used electromagnetic devices. This book deals with LEAs that convert electric energy into controlled mechanical motion of limited travel and LEGs that transform mechanical energy into electric energy. Examples range from loudspeakers and microphones to magnetically levitated material transfer in ultraclean rooms. Much of the literature on linear actuators and generators covers the principles of operation and performance calculations of these devices. Little has been published on their control or on detailed design methodologies. This book presents the first unified treatment of the subject, including the construction, operation, control and design of LEAs and LEGs. Chapters describe linear induction, permanent-magnet, linear reluctance, switched reluctance, and linear stepper actuators, as well as various types of linear electric generators. The text is amply illustrated with numerous design examples.
