Abstract: The invention discloses an aluminium salt for use in the treatment and prevention of dementias associated with ?-amyloid deposition, preferably AD.

Abstract: The disclosure relates to an electric blower apparatus having a blower spiral which has a first axial end wall, a second axial end wall and a blower air outlet. An electric motor which drives a fan wheel rotating in the blower spiral is held on the first axial end wall, the fan wheel inducting ambient air by way of an intake opening in the second axial end wall. A cover element, the cover surface thereof being configured so as to be larger than the air inlet surface of the intake opening, is disposed in front of the intake opening. To induct a large quantity of ambient air with little noise, it is provided that the cover element is configured as a cover plate, wherein an annular gap which forms the intake channel for the direct access of ambient air is configured between the plate edge and the blower spiral.

Abstract: A blower unit for a portable handheld blower apparatus has a housing section and a tubular receiving space, formed in the housing section, with a first axial end and a second axial end and with a longitudinal center axis. Arranged in the receiving space of the housing section is an axial blower for generating a blower air flow, the axial blower being driven by a drive motor. The receiving space has an intake opening at its first axial end and a discharge opening at its second axial end. In order to reduce operating noise, an air guide plate is arranged at an axial distance in front of the intake opening, the air guide plate having external dimensions that are greater than the external dimensions of the intake opening. An annular gap that supplies intake air is formed between the air guide plate and an outer periphery of the housing section.
