Model Steam Turbines (Classic Reprint): How to Design and Build Them; A Practical Handbook for Model-MakersExcerpt from Model Steam Turbines Steam turbines may be divided into two classes: the impulse or action type, in which a jet of steam or ? uid at high velocity impinges on a number Of vanes or paddles fixed around the rim Of a wheel free to rotate, and the reaction type, more generally known as Hero's Engine or Barker's mill. Both these types are pretty familiar to us from our Childhood's days, in the windows of the toyshop, and no doubt in many cases

Excerpt from Model Steam Turbines

Steam turbines may be divided into two classes: the impulse or action type, in which a jet of steam or ?uid at high velocity impinges on a number Of vanes or paddles fixed around the rim Of a wheel free to rotate, and the reaction type, more generally known as Hero's Engine or Barker's mill. Both these types are pretty familiar to us from our Childhood's days, in the windows of the toyshop, and no doubt in many cases (the writer's also) formed our first steam model. They are illustrated in figs. 1 and 2, and frequently appear in patent specifications, though, of course, with considerable modification. In order that the principles on which these machines are designed and for which they depend on their action may be thoroughly understood, the following elementary mechanical considerations are necessary.

The tennis balls are very well made.
Color: Yellow, Size: 20 PACK
Bought this bag of tennis balls for my son’s dog. He has a tennis ball launcher that he shoots and she runs to get the ball and bring it back. Perfect training toy!

Great value.
Color: Yellow, Size: 20 PACK
They bounce and they float. Color is bright. Great for my dogs. I let my dogs use these instead of the ChuckIt brand when unsupervised because they tend to get punctured.

Great color but destroy easily
Color: Orange, Size: 20 PACK
These balls are easily visible and excellent in situations where green balls may be difficult to find. I only take these balls out to play fetch. The balls only last a couple of fetch sessions before being destroyed.
