摘要:
Epoxy resin mixtures suitable for producing halogen-free flame-retardant composites by the injection process comprise the following components: (A) a phosphorus-free aliphatic and/or aromatic and/or heterocyclic epoxy resin; (B) an epoxide group-containing phosphorus compound; (C) a phosphorus-modified epoxy resin with an epoxide value of from 0.02 to 1 mol/100 g, obtained by reacting polyepoxy compounds having at least two epoxide groups per molecule with phosphinic anhydrides and/or phosphonic anhydrides or with phosphonic monoesters, followed by thermal elimination of alcohol; and (D) as hardener, at least one primary or secondary aliphatic polyamine with NH and/or NH2 groups.
摘要:
An x-ray device is provided. The x-ray device includes a C-arm, on which a radiographic source and a heat pump are arranged. At least sections of the C-arm are hollow, such that at least sections of the radiographic source and the heat pump are arranged inside the C-arm.
摘要:
A patient support device which can be connected to patient placement devices of medical examination or treatment equipment, for example an MRI device, an X-ray machine, or of ambulances. The patient support device supports a patient during medical examination and treatment. The patient support device has a structural rigidity that is less than a minimal rigidity that enables the patient support device to be self-supporting while the patient is resting thereon. Such a patient support device can be designed in a simple manner in such a way that it can be used in MRI devices, as well as in devices of other types, and can be transferred between the devices without repositioning of the patient on different support devices.
摘要:
The embodiments relate to a medical device and to a method for controlling a movement of the mobile medical device. The medical device includes a chassis and a control apparatus, wherein the medical device is embodied by the chassis to perform a movement in at least two spatial directions on a plane of motion and to execute a rotary movement about an axis of rotation standing perpendicularly on the plane of motion, and the control apparatus is embodied for controlling the chassis.
摘要:
Disclosed are insulating electric conductors against partial discharge and a method for producing an insulation system having improved partial discharge resistance and such an insulation system. There is an erosion-inhibiting effect of adhesion promoters, such as organic silicon compounds, added to resin when admixing nano particulate fillers. Good results may be attributable to a type of particle wetting of the nano particles as a result of particle wetting with organosilanes. The admixture of adhesion promoters with the resin before the addition of the nano particulate filler provides considerable advantages.

摘要:
Optical fiber cable with at least one optical fiber, with a jacket enclosing each and every optical fiber, and a waterproofing agent, wherein the waterproofing agent comprises a duroplastic support material and a swell powder embedded into the duroplastic support material.
摘要:
An insulating system having improved partial discharge resistance includes an insulating tape around a conductor. The tape is a mica tape joined to a carrier. The tape is impregnated with a synthetic resin, and is interspersed with a nanoparticulate filler, present bimodally, in the form of two fractions of the filler differing in particle size and fraction size. An adhesion promoter may be in the resin.
