Inventor: BARDELLI LODOVICO
IPC: B28B3/02

Abstract: A method for moulding uniformly compacted tiles comprises forming a test tile (11), measuring the hardness or compactness of said test tile at a large number of points on its surface, locally varying the thickness of the punch (1) for forming the reverse face of the tile in those regions of the punch corresponding to those tile hardness values which most differ from the mean value of the largest number of measurements of approximately equal value. 
     Said three operations, namely forming, measuring and varying, are then repeated until a substantially uniformly compacted tile (111) is obtained, after which other tiles (111) are continuously moulded until the pressing conditions change.

Abstract: The invention relates to a method for production of leaf springs and axle steering devices of fibre-reinforced plastic, in which preforms fabricated from high-strength fibres, such as glass fibres and/or carbon fibres, impregnated with heat-curable resins are provided, in which preforms any eyes required are integrated. The method is distinguished in particular by the fact that the compressing and curing of the moulding are carried out separately from each other. The preform, placed in a compression mould preheated to about T0 = 90 DEG C, is heated under a clamping pressure of P1 = 20 to 50 bar to a moulding temperature of T1 = 90 to 120 DEG Celsius. Only once the moulding temperature T1 has been reached is the full moulding pressure P2 applied, which is maintained during the subsequent curing process at a temperature of T2 = 120 to 160 DEG Celsius. The advantages attained with the invention are in particular that the cycle times are significantly reduced in comparison with the conventional methods, there is no need for heavy presses and correspondingly designed heatable single or multiple compression moulds and that a more uniform consistency and consequently an improvement in quality of the moulded components is achieved. <IMAGE>

Abstract: The present invention consists in a process for obtaining polymers with antiviral activity which is characterized in that beginning with oligo or polysaccharides with a specific structure, polymers with a specific number of carbonyl groups are obtained by oxidation; in that the carbonyl groups of the oxidised oligo/polysaccharides are made to react with amino groups of molecules carrying amino and sulfonated groups, such as aliphatic amino-sulfonates, in water or in mictures of water with water-miscible solvents, under specific temperature, time, and pH conditions, giving rise to polymers carrying sulfonated groups, which are purified by conventional processes; in that the sulfonated polymers thus obtained have antiviral activity and either lack or present very low toxicity and anticoagulant activity, and are thus suitable for the production of pharmaceutical preparations suitable for use in topical or systemic antiviral therapy in humans or in animals. It is applicable in the pharmaceutical industry.

Abstract: Optical metrology method and apparatus wherein three optical wavelengths of a fixed polarization are generated and separated into a reference beam (RB) and a measurement or object beam (OB) having, ideally; equal optical path lengths. After reflecting from surfaces being measured OB is combined with RB and provided to sensors which measure the intensity associated with each of the wavelengths. Any difference between the intensities is indicative of a difference in the optical path lengths of OB and RB and is a function of the polarization state of each of the three returned wavelengths. Differences in optical path length may is indicative of a difference between a reference surface and a test surface, or a difference in thickness or index of refraction across an object. Two multi-mode laser diodes (12,14) are provided for generating the three optical wavelengths. Two synthetic wavelengths are derived from the three optical wavelengths and are employed to improve the precision of measurement while retaining a large dynamic range made possible by the use of a large synthetic wavelength.

Abstract: Computer elements in a massively parallel computer system are interconnected in such a way that the number of connections per element can be balanced against the network diameter or worst case path length. This is done by creating a topology that maintains topological properties of hypercubes yet improves flexibility by enumerating the nodes of the network in number systems whose base can be varied. Topologies are generated in which nodes are not always connected when their addresses differ in a single digit. A new variable d is introduced, the purpose of which is to control the overall density of the network by controlling the number of intermediate arc connections within the rings of the network.
