In a system for evacuating air from moulds for vulcanizing tyres, the air and vulcanization gases trapped in the various interstices of the mould (1) are evacuated to the outside of the moulding part through a part which serves as a vent (3) and which contains one or more direct passage chambers (4) of constant width on the so-called bottleneck part which are dimensioned so as to prevent the passa...

The invention relates to the use of complexes and chelates resp., of antibiotics, especially azithromycin, with bivalent and/or trivalent metals in the obtaining of antiulcer drugs, to new complexes and chelates resp., of antibiotics with bivalent and/or trivalent metals and to processes for the obtaining thereof.

The invention is a process for preparing a polymeric liquid crystal composition, e.g., a film or fiber, comprising aligning a nematic or smectic monomeric mesophase (liquid crystal monomer) and photopolymerizing the mesophase, characterized in that the mesophase is aligned in a multi-oriented state prior to photopolymerizing the mesophase. Preferably, alignment is a two or more step process wherei...

The present invention relates to a device suitable for the continuous disinfection and removal from small supplies of drinking water of nitrate/nitrite ions as well as other adsorbable organic impurities as well as to a process used in conjunction with the proposed device. In this arrangement, three or more containers are arranged in series in the flow direction (A,B,C,D) to form a unit, wherein t...

A system is disclosed which operates to collect high resolution three-dimensional surface mesh data from mechanical components which are used for component evaluation. The system includes a multidimensionally movable fixture mount for holding the mechanical components. A structured light pattern emitting projector is provided together with an image sensing camera for detecting impingement of the l...

The device consists of a single body with pair of shutters in the shape of isosceles trapezoids (1 and 2) hinged linearly (3). One shutter (1) on the internal side has, delimited by the lodging seat (6) of the precluding aperture edge, a pair of linear springs (4-9 and 5-10) to produce pressure and thereby latching the other shutter (2). The device is opened by utilization of the two tongues (7 an...

This is the invention of a new type of elastic gasket, possibly made of silicone and non-toxic, specifically made to put the fluids on the ceramic tiles of the faucet that controls the flow of water and where these are equipped with a single control metal cartridge. This gasket is characterized by the fact that it was given the size and shape to make it able not only to carry out the functions for...
