This inventive change is to the family of umbrellas. Instead of being a folding circular cover of nylon etc. attached to ribs from a stick, that someone would carry, or a larger folding marketing type, this umbra or penumbra, (part shade) as I will refer to it, differs as follows: The penumbra construction is based on a suspension system, built of plastic or aluminium, etc. Because of its size, (t...

This invention relates to a process for crystallizing and solid state polymerizing polymers, in the form of amorphous pellets by coating the pellets with a coating of 50 to 250 ppm of an anti-sticking agent to the amorphous pellets. The invention also relates to such a coated pellet. The coated pellet is then heated such that its surface is at least partially crystallized or essentially crystalliz...

For the assembly of a spring-type brake cylinder, a rear cylinder is provided with a preloaded spring, with a rear piston and with an intermediate flange. Then, a front cylinder, in which a front piston with an actuating rod for a brake element of the braking system is movably arranged, is fixed to the rear cylinder, so that the rear cylinder and the front cylinder are in contact with one another ...
