Excerpt from A Book of Cambridge Verse Nevertheless, after all deductions have been made, how much true poetry is yet left! He must be hard to please who cannot find intense enjoyment in the Eclogues of Phineas Fletcher, in Cowley's epitaph on Harvey, in the Miltonic stanzas of Gray's Installation Ode, in a score of other pieces, grave, quaint, or classical in their allusive ness of phrasing. Especially grateful must we be to the number of poets, of exquisite feeling and easy mastery of form, who during the last fifty or sixty years have enriched the language with delicate and elegant verse, from which it has been only too difficult to choose because its quantity is so great and its merit so even. Of this we trust we have given a tolerably adequate selection but it would have been easy to multiply it fourfold.

Excerpt from Industrial Colonies and Village Settlements for the Consumptive Symonds, and we together examined the patients, sampled the climate and other conditions, and argued with Unger and Ruedi. Then for the second time came Hope; more solid Hope. Given a fairly early case, and three years, and recovery was in the offing. And so we went on cheerfully with Davos. But Davos was not for every one; nor was every case an early 'one. Then came the discovery that lower altitudes would do if certain conditions were obtained; and so arose the great sanatorium movement. But slowly we found that patients could not spend their lives in sanatoriums; and one day on making my way up to one of them in England, I met on the way patient after patient, slouching along, bored to death with themselves and with each other; and even worse in morale than in body. Better discipline and better notions of thera peutics mended some of that; still I could not forget those listless saunterers, and it became evident to some of us, however unwillingly, that Hope was drooping again. The sanatorium was doing a great educative work no doubt; but at the end of its four or six months - what then? To send the patient away with recommendations about light jobs, and a regime, was almost a mockery or quite. What about the wage, and the family to be supported? The next lesson was brought home to me by a visit with other commissioners to certain cities, concerning some such problems. Before me now I see a gaunt hollow-eyed man, coughing, and leaning against the wall as he tried to talk to us, saying that his mates when he came out of the sanatorium - good fellows as they were - had bought him a milk that he might creep round, and earn a bit. The brave wife, shawl on head and mill apron on, had just come from the factory, and apologised for the dirty house - as well she might. The poor thing was working all day at the factory to keep the wolf from the door. All being dragged down together into the pit! What is the value of a good house, or a clean house, if no wages! What is there for the children? And what is to stop the infection! Who then would have the imagination, the initiative, the business capacity, to lift this burden, like lifting a world?

Often called the workhorse of industry, the advent of power electronics and advances in digital control are transforming the induction motor into the racehorse of industrial motion control. Now, the classic texts on induction machines are nearly three decades old, while more recent books on electric motors lack the necessary depth and detail on ind

The Field Orientation Principle was fIrst formulated by Haase, in 1968, and Blaschke, in 1970. At that time, their ideas seemed impractical because of the insufficient means of implementation. However, in the early eighties, technological advances in static power converters and microprocessor-based control systems made the high-performance a. c. drive systems fully feasible. Since then, hundreds of papers dealing with various aspects of the Field Orientation Principle have appeared every year in the technical literature, and numerous commercial high-performance a. c. drives based on this principle have been developed. The term "vector control" is often used with regard to these systems. Today, it seems certain that almost all d. c. industrial drives will be ousted in the foreseeable future, to be, in major part, superseded by a. c. drive systems with vector controlled induction motors. This transition has already been taking place in industries of developed countries. Vector controlled a. c. drives have been proven capable of even better dynamic performance than d. c. drive systems, because of higher allowable speeds and shorter time constants of a. c. motors. It should be mentioned that the Field Orientation Principle can be used in control not only of induction (asynchronous) motors, but of all kinds of synchronous motors as well. Vector controlled drive systems with the so called brushless d. c. motors have found many applications in high performance drive systems, such as machine tools and industrial robots.
