Abstract: "MICROBUBBLE PRECURSORS AND METHODS FOR THEIR PRODUCTION AND USE" Microbubbles are formed in a liquid, e.g., blood in order to alter the transmission characteristics thereof to electromagnetic and sonic waves transmitted therethrough, by dissolving therein a solid particulate material, preferably as a suspension in a carrier liquid in which the particulate material is at least temporarily stable, the particles of which are substantially free of microbubbles and have a plurality of gas-filled voids communicating with the surface of the particles and providing nuclei for microbubble formation and the ratio of the mass of the particles to the volume of gas in the voids is sufficient to render the liquid in which the particulate material is dissolved supersaturated with respect to the gas in the voids in the area of the liquid surrounding the microbubbles when they are formed.

Abstract: Process and apparatus for attaching small tear-open strips to packaging material or the like A b s t r a c t (in conjunction with Figure 3) The feeding of small tear-open strips to a blank or to a sheet of packaging material is a special problem in packaging technology, especially when high performances have to be achieved. The present apparatus makes it possible to feed small strips in a timed sequence and to apply them to a sheet of packaging material by the use of conveying members which are effective only in one direction in relation to a continuous strip for forming the small strips, so that the strip is respectively pulled along in portions. As a result, a high performance and especially the transition from intermittent conveyance of the strip to continuous transport of the sheet of packaging material are possible.

Abstract: Abstract In manufacturing a field effect transistor, a pattern which has a wider upper layer and a narrower lower layer is formed at a gate electrode position.  Using the pattern as a mask, first and second impurity regions are formed on both sides of a gate region by ion implantation.  Subse-quently, at least the lower layer is buried in a material, such as an organic high polymer material, having a selec-tivity in etching characteristics with respect to the pattern material.  After removing the lower layer, an electrode material is embedded in the resulting hole to form a gate electrode.  The result is a method that, while using conventional photolithography, enhances fabrication at the submicron level and achieves improved accuracy of alignment.

Abstract: A b s t r a c t The invention relates to a manually operated shearing machine, driven by an ordinary drill, intended for shearing sheet-metal thicknesses up to about 5 mm.            The machine comprises a body (1) provided with support wheels (24, 25), two cutting wheels (5, 6) cooperating with each other on the body (1), the sheet-material being sheared between the cutting edges (18, 19) thereof.     The cutting wheels (5, 6) are arranged obliquely at an angle .alpha. to the normal plane of the sheet-material to be sheared. Furthermore, the free side faces (12, 13) of the shearing wheels (5, 6) are bevelled close to the shearing edges (18, 19) at the same angle .alpha. , forming peripheral surfaces (16, 17). The shearing wheels (5, 6) are also arranged in such a way in relation to each other that said peripheral surfaces (16, 17) lie in the same plane and form a nip (20). Thus, after sharpening of the cutting edges (18, 19), for example, the position of the shearing wheels (5, 6) in relation to each other can easily be adjusted by vertical displacement of one of the shearing wheels.

Abstract: ABSTRACT OF THE DISCLOSURE           Apparatus for removing gaseous components and/or solid impurit ? from a gaseous fluid flow includes a pre-purification section and a fine-purification section in fluid communication therewith and in which a rotatable scrubber impeller is situated.  A first device introduces a first scrubbing liquid into contact with the gaseous fluid flow in the pre-purification section to pre-purify the same.  The pre-purified gaseous fluid flow is con-ducted to the region of the scrubber impeller in the fine-purifi-cation section and a second device introduces a second scrubbing liquid into contact with the pre-purified gaseous flow as the latter is conducted to the region of the scrubber impeller.  The flow of the pre-purified gas is accelerated as it is conducted to the region of the scrubber impeller, such as through a conduit which tapers in cross-section in the direction of gaseous fluid flow therethrough.  An extremely fine scrubbing of the gaseous fluid is obtained in a reliable manner without the need for large quan-tities of scrubbing liquid.

The strip includes a succession of spaced coupling elements, each having a pair of first and second legs extending from a head in a common transverse direction.  A plurality of first and second solid connecting portions is disposed alternately at opposite sides of the strip and extends one between each adjacent pair of the coupling elements.  The individual connecting portions are more slender than the coupling element legs.  The two adjacent legs interconnected by each connecting portion terminate in a combined broad foot with opposite corners or ends thereof substantially acute angled and thus not chamfered.          The invention improves the stability of the engagement of the elements with the flanges of an associated slider.
