In most cooking ranges or stoves (Electric or Gas) having more than one heating elements or rings, the latter are placed in separate locations on the cook-top, and, they are of various sizes, thereby providing options of using various sizes of heating area. This allows for accommodating, economically and efficiently, various sizes of pots and pans and other cooking utensils.

Dendrite or asteroidal titanium dioxide microparticles having a length of 0.2 to 0.5 .mu. m, a thickness of 0.05 to 0.1 .mu. m, and a specific surface area of 20 to 130 m2/gram, are produced by treating hydrated titanium oxide particles with an alkali, mixing instantaneously the resulting reaction product with an amount of hydrochloric acid in a ratio of 1 to 4 mols of hydrochloric acid to one mol...

Method of calibration for wheel-balancing machines for motor vehicles, comprising at least one starting of the shaft of the calibration machine at a certain nominal velocity with a single specimen weight applied to it, during which the machine is used to calculate a first imbalance P2 at a shaft rotation velocity of ω2, a second imbalance P1 at a shaft rotation velocity ω1 which is lower than ω2 a...

Device comprising at least one planar cruciform element consisting of, and decomposable into, five individual elements, known as tesseras, one positioned at the centre of the cruciform element (central tessera) and four which are identical to each other and different from the central tessera, placed at the vertices of the latter (vertex tesseras). The tesseras have a generally square shape and the...

Twin-front strongroom, whose internal space is accessible, via armoured doors, from two opposite sides, especially for banking transactions, in which the main internal space of the strongroom is subdivided into a plurality of smaller spaces, known as vaults, each of which is provided with two opposite counters and therefore itself has a twin-front nature; the main internal space also comprises a s...

The drawer type profile, co-operating with an elastic means, ensures the reliable locking of the vertical position of the headrest, upon engagement of a tooth in a corresponding notch with a specific profile of each support rod, while when adjusting the height the operator, by pressing a pushbutton, brings about the disengagement with sliding of said drawer; upon releasing the button in the desire...
