    Abstract: The invention relates to the use of either an aqueous extract or an organic extract of the plant Thymus to prepare a pharmaceutical composition useful to inhibit the growth of Helicobacter pylori and the urease activity of Helicobacter pylori. In case of an aqueous extract, a minimum amount of 0.5 mg of the dry plant in the extract is required but the preferred amounts are above 1.2 mg. The aqueous extract may be used either as a drink, with or without additional ingredients, or transformed into a capsule or a paste. The invention also relates to in-vitro methods for inhibiting the growth of the urease activity of Helicobacter pylori.

    Abstract: A method of obtaining a mask for X-ray lithography having a thin oxidized metal membrane supported on an annular silicon base. The method consists of the following steps: (a) deposition of a metal layer on a silicon wafer; (b) oxidation of the metal layer to form a continuous thin oxide layer; (c) etching selectively a portion of the backside of said substrate, obtaining a thin membrane of oxidized metal at the etched portion; and (d) obtaining a pattern delineation through a photoresist on said membrane framed by the silicon substrate. A most preferred deposited metal is aluminum which is converted to aluminum oxide. Then a portion of the silicon substrate is removed in order to expose the aluminum oxide membrane attached to the remaining silicon substrate. The mask prepared according to the present invention does not suffer from any distortion and preserves its accuracy even under the stresses incurred during the mask preparation and use.

    Abstract: The present invention relates to a new technique and device for mass transport operation and physical separation, being substantially quantitative and involving selective barriers. According to the new technique, the mass transport through the selective barrier and physical separation are carried out in the same device. The device consists of a mixing-reservoir into which is fitted snugly a mixer-separator, having a channel in the vertical axis of the mixer-separator, the mixer-separator being provided with means for accumulating a gas pocket to decrease the pressure exerted on the barrier. The completely solid-free liquid passing through the selective barrier is removed by pushing in the mixer-separator, said liquid being accumulated in a collecting container. Typical examples of such selective barriers are: membrane, bed of adsorbent material, paper, plastic, glass and metal filters or any other porous material, hollow fibers etc. The new technique and device can be successfully utilized in any operation involving separation of solids from liquids and particularly useful in immunoassay, sterilization, ultra-filtration, desalination by reverse osmosis, etc.
