  • Isoindoline pigment having improved low shear dispersibility
    Patent number: 6143067
    Abstract: A pigment composition, which comprises70-95% by weight of a pigment of formula ##STR1## 5-15% by weight of at least one C.sub.2 -C.sub.16 alkylenedicarboxylic acid-di-C.sub.1 -C.sub.12 alkyl ester; and0-15% by weight of at least one C.sub.12 -C.sub.24 fatty acid ester of polyhydroxy-C.sub.2 -C.sub.12 alkane;each based on the total weight of the pigment composition.Also claimed is a process for the preparation of this pigment composition and its use for mass-colouring in particular high molecular weight organic materials which can be moulded as plastics or melts.The products obtained are distinguished by an improved low shear dispersibility effect at high tinctorial strength.

  • Self-washing device for separating and filtering solid particles from a flow of liquid, and use of the device in a fuel injection circuit
    Patent number: 6125826
    Abstract: A self-washing device for separating and filtering solid particles from a ow of liquid includes a tubular casing defining an internal chamber, a tangential liquid inlet opening into the internal chamber and arranged to create a vortex in the internal chamber which acts to centrifuge out solid particles and carry them at the vortex periphery, a tangential liquid outlet for discharge of liquid carrying the solid particles from the internal chamber, and a tubular filter disposed longitudinally within the internal chamber for taking and filtering a portion of liquid flow at a center of the vortex, the filter having a longitudinal central duct communicating with at least one longitudinal liquid outlet for the filtered liquid. The device is of particular use in a fuel injection circuit.

  • Colored pearlescent pigments
    Patent number: 6113683
    Abstract: Colored pearlescent pigment comprising a pearlescent pigment and a second pigment, characterized in using an adhesion promotor for the mutual adsorbance of the pearlescent pigment and the second pigment, whereby the adhesion promotor is a polymer containing hydroxy groups, a process for its preparation, its use and a colored high molecular weight material.

  • Aircraft hot-air supply system
    Patent number: 6058725
    Abstract: The present invention relates to a hot-air supply system for an aircraft equipped with at least one engine (2) with a fan (3) and compressors (4). According to the invention, the regulating devices (14, 15, 16) intended to regulate the flows of hot air and of cold air sent by the pipes (10 and 11) to the heat exchanger (12) are pneumatic, controlled electrically, and are controlled by a centralized management device (24).
