  • Patent number: 4992525
    Abstract: Cationic resins based on epoxy resins which are modified through the introduction of phosphoric acid segments and the process of producing the resins are described. The reaction of the phosphoric acid is carried out in a multiple-step process whereby, in a first step, the diester is formed through reaction of ortho-phosphoric acid with 2 moles of a monoepoxy compound or through reaction of a polyphosphoric acid with n-1 moles of a monoalcohol and subsequent reaction with n+1 moles of a monoepoxy compound. The remaining acid group is reacted with a di- or polyepoxy resin. The products obtained can still contain unreacted epoxy groups. The protonable groups are introduced via the epoxy groups and/or via the hydroxy groups present or set free by opening of the oxirane ring. The binders can be combined with hardening components or may be formulated as self-crosslinking binders. The binders have excellent resistance to corrosion when stoved as electrodeposited coatings.

  • Patent number: 4990579
    Abstract: Crosslinking cationic paint binders, preferably cathodically depositable paint binders comprising (poly)-2-hydroxyalkylurea compounds as a crosslinking agent are described. The 2-hydroxyalkylureas are obtained by reacting organic polyisocyanates with secondary beta-hydroxyalkylamines. The crosslinking agents of the invention permit film formation in the stoving range of about 140.degree. C., which is particularly favorable for water-based paints. Additionally, selective semi-blocking which is made possible through the difference in reactively between the NCO-groups of individual polyisocyanates is enhanced through use of the secondary amino groups, in comparison to through use of hydroxyl groups which are conventionally used.

  • Patent number: 4988259
    Abstract: A modular manipulation arm formed from successive elements, each of which can pivot relative to the preceding one about a pivot axis coinciding with the axis of the element in question, and can pivot relative to the following one about a pivot axis which meets the axis of the element in question obliquely. These pivotings are obtained by means of rotary jacks which cause a drive-shaft portion to rotate relative to the corresponding element and which immobilize it in the selected position. The jacks are each associated with a distributor, itself preferably controlled by a low-power electric motor. The connection between successive elements preferably comprises a cardan joint linking the elements and oblique bearing surfaces at the end of the drive-shaft portions.

  • Patent number: 4986215
    Abstract: A susceptor for use in a vertical vapor-phase growth system designed to heat substrates by means of heat transferred and radiated from a susceptor heated to cause vapor-phase growth on the substrates. The susceptor has a large number of spot-faced portions for receiving substrates, respectively. Each spot-faced portion has a concentrical circular ridge to define a pair of inner and outer spaces at the inner and outer sides, respectively, of the ridge, each of the inner and outer spaces having a concave bottom having a circular radial section, so that a substrate is supported by the circular ridge. Thus, the substrate is uniformly heated by means of the RF induction heat from the susceptor, so that generation of a thermal stress exceeding the critical strength of the substrate is suppressed and substantially no slip occurs.
