A polypropylene composition comprising 100 parts by weight of a crystalline propylene polymer having a molecular weight distribution (Mw/Mn) of less than 5.0 and from 0.0001 to 1.0 part by weight of a crystal nucleating agent, the composition having a crystallization temperature at least 1.5.degree.C higher than the crystallization temperature of the crystalline propylene polymer.

The present invention is directed to a solid poly-amphiphilic polymer. The polymer may be (1) a continuous film (a) which is strengthened sufficiently by cross-linking to be used alone and/or supported on a frame, (b) overlaid and/or cast on a porous hydrophobic support or (2) introduced into the pores of a microporous hydrophobic membrane. The present invention is also a process for selectively r...

Apparatus for forming a plastics coated metal tube comprising means for forming a continuous strip of metal into a U-shape and a forming sleeve for folding the strip into an overlapping tube. A mandrel (23) is also provided which extends through the forming sleeve and through a locating sleeve (30). The locating sleeve (30) centralises the tube as it passes over the mandrel and welding means are p...

An apparatus and method for providing a boom extension for retractable booms of gantry cranes which does not require lowering the boom during attachment of the extension, or increasing the lift capacity of the boom hoist machinery, nor does the boom extension add bending moment to the retractable boom.

The subject of the invention is the compounds of formula (I): in which: - Ar represents an optionally substituted heteroaryl or aryl radical, - X represents a nitrogen atom or a =CH- group, - R represents an optionally substituted alkynyl, alkenyl or alkyl radical or a Salk radical, alk representing an optionally substituted alkyl radical. The compounds of the invention have pesti...

An integrated, multisensory recognition (identification and verification) system is described. Acoustic features (2) and visual features (3) are integrated in order to identify people or to verify their identities. The integration of the speaker-identification and visual-features-identification functions (11, 12) improves both performance and reliability in the applications envisaged. Various arch...

A boat formed by pneumatic elements associated with a rigid bottom, characterized in that said boat comprises a pair of tubular compartments having a variable cross-section tapering toward the bow of the boat, said boat tubular compartments being associated with contoured sidewall elements connecting the substantially rigid bottom of the boat to a boat floor, which are mutually spaced in order to ...

A fork apparatus (1) for assembling reinforcing or supporting ribs in a tunnel consists of a box-like supporting construction with two short abutment teeth (2) on the sides and four abutment teeth (3) in the central part. On the sides, two pistons (4) are arranged for clamping the ribs to the apparatus. In the central part, a base member (12), driven by a small piston (13), operates as an abutment...

This relates to a process for the manufacture of padding for articles of clothing, which provides for the use of a sheet of synthetic fibres which is subjected to spraying or spreading or mixing with thermoplastic resins, subjecting the aforesaid thermoplastic resins and the synthetic fibres of the sheet to heating and performing one or more hot rolling treatments on the sheet processed in this wa...

This relates to equipment comprising a frame fixed on a motor vehicle having four stabilisers of which two are fixed and two extend horizontally. At the centre this frame bears a telescopic arm on a mounting rotating to the right and the left which has a centring-fitting device at the end. To the right and left of the telescopic arm the frame is provided with two mountings each of which carry an e...

In a procedure for continuously crystallizing and polymerizing polyester and polyamide materials, amorphous material is first precrystallized, preferably in a fluidized bed (1,2), then heated up to the reaction temperature in a preheating zone (4) and finally polymerized and largely liberated from byproducts in a reactor (3). In this procedure, material from the discharge area of the preheating zo...

A novel xylanase, obtained from Bacillus subtilis strains, is provided which improves the consistency and increases the volume of bread and baked goods containing it. B. subtilis DSM 7147 containing the plasmid pIK 91 produces the xylanase. Genetic engineering insertion of the gene encoding the xylanase in the plasmid pUB110 is described.

The requirements made on the properties of pigments, which are becoming increasingly more specific, especially in the areas of emulsion paints and printing inks, necessitated the development of specific and environmentally friendly dispersants, emulsifiers and coupling assistants. The compounds according to the invention are esterification and/or arylation products of natural or modified castor oi...
