Abstract: A rotary pump with an improved seal on a control pressure chamber, including: a housing having a delivery chamber; a feed wheel rotatable in the delivery chamber; an actuating member surrounding the feed wheel forming delivery cells and moveable in the housing relative to the feed wheel. The control pressure chamber is delineated by the actuating member together with axially facing axial co-operating surfaces, forming an axial sealing gap and a radial sealing gap. A control fluid can be introduced into the control pressure chamber for applying pressure to the actuating member to exert an actuating force in the actuating direction; a restoring device for generating a restoring force; and a sealing element arranged on the actuating member or the circumferential co-operating surface. To compensate for a change in gap width of one of the axial sealing gaps, a base leakage cross-section is provided on the sealing element.

Abstract: The present invention relates to isometric agglomerates of an essentially spherically shaped form, especially bath beads, and the cosmetic, therapeutic and hygienic use thereof. The invention is especially concerned with agglomerates on the basis of carriers of natural origin such as collagen, gelatine, starch, cellulose or urea, which comprise both lipids and vesicle forming agents as well as emulsifying components and optionally additives, without impairing the stability or activity thereof. The agglomerates when contacting water, especially in a bathing, will form liposomal mono- up to multi-layer structures thereby enabling an improved transport of active compounds. This will result in an improved balneological/or therapeutic action as well as a caring effect in the sense of a reconstruction of the skin barrier function.

Abstract: The invention generally relates to tuning arrangements and tuning components for influencing an electric field in a microwave device, in particular in a microwave communication device such a microwave circulator and isolator, comprising a tuning element having a tuning portion which co-operates with the housing of the device in an electrically non-conductive manner.

Abstract: The present invention relates to a new type of solid balneological preparations for cosmetic, hygienic and therapeutic use, which has both the properties of a solid bath additive and those of liquid products, and is characterized especially by the addition of lipid components, vesicle forming lipids, tensides and, in some cases, mineral salts. Active components, adjuvants such as stabilizers, adsorbing substances, lubricants as well as smoothing and breakdown promoting agents may also be contained therein.
