The invention provides a novel shaped product comprising a sheet material of polyurethane resin material reinforced with binder-free natural-fibre material, such as jute, flax, hemp, coir, ampas, ramie or cotton, possibly combined with polypropylene, polyethylene and/or glass fibres. A preferred fibre material is jute, preferably in the form of jute needled felt. The invention also provides a proc...

Device for estimating motion in an image sequence comprising first, second and third image memories (10, 20, 30) placed in series in order to continuously ensure the respective storage of three successive images labelled for example by their rank 2k, 2k + 1, 2k + 2 in the image sequence, and a recursive displacement estimator (40) receiving the output from the said first and third image memories i...

In the synthesis of amikacin, having the formula: by acylation of a diprotected derivative of kanamycin A with a reactive derivative of L-(-)-4-amino-2-hydroxybutyric acid, the selection of the reaction solvent and of the pH conditions permit the industrial economicity and the synthesis yield to be improved.

A crash barrier according to the invention comprises wooden posts (1) supporting a horizontal rail (2) composed of round wooden elements (31, 32 ...) which are assembled end-to-end by means of two metal strap plates (41, 42) and by means of bolts (5). The strength of the assemblies is reinforced by incorporating, in the ends of each round wooden element, vertical metal rods (8) which intersect the...

The tubular and tight profile connects the body front and rear points, following the bottom line of the hull, and houses tanks for bunkers, bilge water and trimming weights. It follows the hull sides internally along their whole or part length. - The tubular profiles (1) are bent in a plane, and joined at an angle to each other so that the prepared hull is given the desired shape. Along the bottom...

The liquid enters into a cylinder which is supported within an outer cylinder . It then passes out through a folded net sock . This acts as a filter The work can be pulled out through the tube and collected via container eg a plastic bag.

Each game piece is formed by one or more components (6), each with the same shape and size as the figures on the gaming area. Each component has fixtures (7a,7b,7c,7d) enabling them to be assembled to form pieces of different configurations. The pieces cover a number of figures on the gaming area.

The space between adjacent components (1',1") defines a track (4) which is filled with a hardening substance, e.g. mortar (6). In each of the side edge surfaces are recesses into which the mortar can penetrate, forming a mushroom-shaped projection (7,8) which prevents or counteracts longitudinal movement of the components in relation to one another.

The holow formations (6) at one end of the track (2) are shaped to accommodate partly the lower end of a skittle, and partly the lower half of a game ball.

A concrete bridge consists of bridge deck elements 11 in the form of hollow deck elements which are arranged alongside each other and which have longitudinal internal recesses 12 placed alongside each other and essentially in the shape of circular cylinders.
