Three Bears

It's a sunny morning in the Big Forest and the Bear family are just waking up. Baby Bear goes downstairs and sits in his small chair at the table. He looks into his small bowl. It is empty!

"Who's been eating my porridge?!" he squeaks.

Daddy Bear arrives at the table and sits in his big chair. He looks into his big bowl. It is also empty!

"Who's been eating my porridge?!" he roars.

Mummy Bear puts her head through the serving hatch from the kitchen and screams, "For God's sake, how many times do we have to go through this? I haven't made the porridge yet!!"

Black American patent

In 1897, a U.S. patent for an improvement in "Casting Composite or Other Wheels" was issued to black American inventor E.R. Robinson (No. 594,286). It gave a method for casting wheels wherein the outer sides are of one metal and the interior portions are of another metal. The importance was not only to enable casting a metal of high electrical conductivity, such as brass, in a groove of an iron trolley wheel - but also to permit an entirely new contruction consisting of two outer disks or flanges and an intermediate, uniting portion, which extends from the contact portion of the wheel with a web extending to the centre and an integral bushing. Robinson also held a previous patent, issued four years earlier, for an "electric railway trolley."[Image: plan view of bottom section of a wheel three-part mold]
