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: An antenna feed device (100) having a first waveguide (102) and a second waveguide (104) separated from the first waveguide (102), each of which is assigned to feed one polarization of a dedicated antenna and each of said waveguides exhibit an overall L-shape form where at least one section of the L-shape of each waveguide is in parallel to the other, both having respectively a first (106) and a second (108) antenna end ending in one plane for connection to an ortho-mode transducer associated with the antenna, while the other sections of the two L-shape waveguides extend in opposite directions, having respectively a first (110) and a second (112) radio end, each of which ends with a single waveguide port for connection to a radio equipment and the waveguides arrangement yields an overall compact T-shape interconnection of the antenna and the radios dedicated to the orthogonal polarizations.

Abstract: An ortho-mode transducer (100) comprising a first part (102) with a first port (106) for connecting a first rectangular waveguide (112) and a second port (108) for connecting a second rectangular waveguide (114). The signals in the two waveguides have orthogonal polarizations. The transducer also comprises a second part (104) with a third port (110)for connecting a common circular waveguide (116) in which the two orthogonal signals can be propagated. Symmetry axes of cross sections of the first and the second waveguides have orthogonal orientation. The first rectangular port (106) has its broad walls perpendicular to the circumference of the common circular waveguide (116) and the second rectangular port (108) has its broad walls alongside the circumference of the common circular waveguide. The first and second ports are connected to the third port in opposite positions via 90-degree bends (118, 120).

Abstract: A circulator comprises a housing in two halves with a ferrite and associated magnet in a central portion of a first one of the halves, the second housing-half above the ferrite having a membrane which is deformable by operation of an adjuster upon the membrane, so as to adjust the size of an airgap between the membrane and the ferrite. The membrane is preferably the residual portion of the second housing-half following a milling operation to provide a recess, the recess accommodating the adjuster in the form of, e.g., a screw. To further enhance predictability of the performance characteristics of the circulator, the ferrite is seated in a hollow formed in the first housing-half and the securing of the ferrite to the first housing-half is by way of an adhesive applied between a lateral face of the ferrite and a corresponding lateral face of the hollow.

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.

Abstract: The invention relates to novel essentially anhydrous oily bath and shower compositions containing a combination of fatty oil and/or fatty or waxy apolar substance, oil-soluble surfactant, and vesicle-forming lipid and, if desired, a cosmetically- or balneologically-active ingredient. When poured into or simply admixed with water, these formulations immediately and automatically, generate dispersed vesicles or liposomes. They exhibit an immediate as well as a prolonged or depot effect, can be used alone or added to or together with existing bath or shower formulations, and are especially suited for use in connection with or as additives to full, partial, or shower baths.

Abstract: The invention concerns a collagen sponge which has a denaturation temperature of at least 37.degree. C., is not cross-linked and in one of its two embodiments forms an optically clear solution in aqueous medium. As compared with the collagen sponges previously known, it is particularly suitable as support material for pharmaceutical and cosmetic active substances since it has a higher denaturation temperature than the latter and dissolves again in contact with body fluid. The collagen sponge of the invention is prepared from an optically clear collagen solution by precipitation with neutral salts, dissolving and reprecipitation and then subjecting the collagen to freeze-drying without removal of the precipitation salt. Acid-swollen collagens and/or cellulose or cellulose derivatives can also be added to the solution, whereby the physical properties of the collagen sponge can be affected.
