And set for preview at this week''s HomeTech are two new models from Polti. The Vaporella 5000R, which is replacing the existing 3500R, has an increased water capacity of 1.5 litres and will retail for around 200 [pounds sterling]. The Vaporella Forever is a retro stainless steel option and will carry a price tag of 230 [pounds sterling]. In May, Polti will be supporting its generator range with a national TV campaign on Channel 4.For De''Longhi, 2002 means the addition of hooded Cabrio models to its already broad range. Each Cabrio model has a cover that protects the iron system and makes it easier to store away.

In 1936 Henry F. Phillips, also once a traveling salesman, patented the cruciform head known to us all. It was first used by General Motors in the 1936 Cadillac, and within three years most screw makers produced Phillips head screws under license from the inventor.The first screwdriver the author found was in the late fifteenth-century castle manual cited above. It appears in the careful drawing of a screw-cutting lathe and was used to adjust the cutter. "Eureka!I''ve found it. The first screwdriver. No improvised gadget but a remarkably refined tool, complete with a pear-shaped wooden handle to give a good grip, and what appears to be a metal ferrule where the metal blade meets the handle....there is no doubt that a full-fledged screwdriver existed three hundred years before the tool portrayed in the Encyclopedie." Since the lathe was shown in a chapter devoted to machines of war "it is likely that screwdrivers appeared first in military workshops, though perhaps not in France, as I had assumed, but in Germany"

Fused fluxes are melted in a furnace, chilled, then lifthydraulicpowerunits crushed and screened for size. These pickup little moisture and recycle without alterations in particle size or composition. Bonded fluxes are powdered materials mixed dry and bonded together with a silicate, pelletized, baked, broken up, and screened for size: the process permits easy addition of deoxidizers and alloying elements. Bonded fluxes allow thicker flux layers when welding and can be identified quickly by color. Disadvantages of bonded fluxes are their absorption of moisture and alterations during handling in panicle size and composition due to particle segregation. Agglomerated fluxes are similar to bonded fluxes except that they use a ceramic binder. They require higher baking temperatures during manufacture, which limits additions of deoxidizers and alloying elements. Mechanically mixed fluxes are combinations of two or more bonded or agglomerated fluxes. They allow special flux mixtures for critical welds, but they may separate during storage, use, and flux recovery.
