摘要:
The invention discloses deagglomerated barium sulphate which has an average primary particle size of less than 0.5 μm and is coated with a dispersant. The dispersant has preferably reactive groups which are able to interact with the surface of the barium sulphate; particularly preferred dispersants are those which are able to endow the barium sulphate with a hydrophilic surface and have reactive groups for coupling to or into polymers. Also disclosed is a plastics premix comprising the deagglomerated, coated barium sulphate.
摘要:
Epoxy resins comprising deagglomerated barium sulphate with an average particle size of less than 0.5 μm feature increased flexural impact strength and breaking extension. Epoxy resins of this kind can be used as, for example, composite material or binders in watercraft construction, in wind turbines, in pipes, for containers or in aircraft construction, in particular in composite materials comprising glass fibre or carbon fibre.

摘要:
A vertical barrel pump wherein the barrel casing is not provided with an integral flange. The flange is a separately produced part whose upper side is engaged by an external shoulder of the barrel before the pump housing is mounted in and is attached to the barrel by way of the flange. The flange can constitute a base plate which is made of reinforced concrete and is embedded in the foundation of the barrel pump.
摘要:
The invention relates to a multi-layered foil body (1) for marking a security document, in particular a banknote. The foil body (1) has at least one color filter layer (2) and at least one change layer (4) with an electrically controllable transmittance and/or an electrically controllable color.
摘要:
A control unit having a microprocessor and at least one electronic memory for storing a program-controlled sequence control for a motor vehicle and a first electronic interface for transmitting the program code of the sequence control from an external data transmission device into the memory and also having a second electronic interface are provided. To prevent manipulation of the contents of the memory, the first electronic interface is irreversibly deactivated after its initial use.
摘要:
The invention relates to a security element for the identification of a security document, in particular a banknote, a valuable paper or a paper document, comprising at least one electrically controllable display element and at least one piezoelectric energy source which controls the at least one display element. The security element is formed by a flexible multilayered film body comprising the at least one electrically controllable display element containing a display layer having liquid crystals that can be oriented in an electric field, and comprising the at least one piezoelectric energy source which controls the at least one display element and has at least one layer composed of piezoelectric material, wherein the security element has a thickness of at most 70 μm in a direction perpendicular to the plane of the film body.
