This relates to compositions for preparations for building which use the sludge wastes from the processing of natural stones (marble, granite, travertine and various stones). These sludge wastes, which are commonly referred to as "slurry", consist of a very fine powder having a particle size of less than 40 μm. The slurry, which contains a percentage of water which varies between 20 and 35% by wei...

The saddle for the entire perimeter of the slot is achieved in closure at the inside of the rear corner, being aligned in symmetry with the opposite front central stitching, and furthermore it is produced by the insertion of two adjacent overturned edges of the lining and stitched to a synthetic plate, in a preassembled shell formed by two plastic rings and countersunk in the padding of the headre...

A single-hull craft with high floating stability, having one hull (11). This single-hull craft comprises means of steering and stabilizing the craft in the water, including a combined keel and rudder (18) pivoting about an axis, which are connected to means (15, 14, 17, 17.1, 16.1, 16.2, 30, 31) of controlling the direction and trim of the said craft, and which, if the craft lists, are operated to...

A proportioning system between the delivery flows of two or more fluids is provided by inserting in each delivery line a chamber sealed by a moving piston and having a pipe for the entry of pressurised fluid supplied through an orifice which is commensurate with the proportionality ratio and capable of bringing about a certain loss of head and an exit pipe for the fluid delivered whose bore or dis...

On the basis of this innovation a base is provided especially of the type for cups and trophies which can take any shape which can be produced by pressing of the shell, the interior being empty to house one or more blocks of cement in order to confer the necessary weight to support the trophy. A substantial feature of the innovation is that it comprises an outer shell 1 constructed of plastics mat...

The invention concerns a box-rotating device for boxes or other small containers, including: at least one alignment element 5 for the boxes 2, to give them a common reference; a rotating frame 6 fitted with parts 1 for holding the boxes 2 to prevent them from moving during rotation; means 3 for detecting the presence of the boxes 2 close to the said alignment element 5, to start the operation of t...

The subject of the invention is a base for a car seat with statically adjustable pneumatic suspension according to the weight of the driver and with a pneumatic damping system for the load, that in practice is variable because of the irregularity of the surface.

Mercaptopolymer composition which is particularly suitable for chromatography. The process for the preparation of this polymer composition comprises the stage of preparing an oxide- based inorganic matrix, modifying the said matrix by treatment with functionalised organosilanes, reacting the said derivativised matrix with a thiolactone or thiosulphone provided with lateral functional group...
