Abstract: A plasma etching apparatus provided with a processing chamber (3) adjustable to be highly decompressed. A pair of parallel electrodes (5, 6) are arranged in the processing chamber and semiconductor wafers (4) are placed on the electrodes. High frequency voltage is applied between the paired parallel electrodes to generate electric field of high frequency, perpendicular to the process face of the wafer, in the processing chamber. Etching gas is introduced into the processing chamber and made plasma in it. An electron supply chamber (10) provided with an electron generating filament (11) therein is connected to the processing chamber. Electrons generated in the electron supply chamber are induced into the processing chamber by induction magnetic field and help the etching gas be made plasma.

Abstract: In the feed of laundry articles (10) to a mangle, the laundry articles are spread apart, approximately centrally in front of a subsequent feed conveyor, by means of two respective clamps (18, 19 and 20, 21) of a spreading device (11), by pulling taut an upper edge (40) of the particular laundry article (10). In known devices of this type, this takes place in a plurality of successive movement phases, and in a last movement phase at a lower speed of the clamps (18, 19; 20, 21) the upper edge (40) is gradually tautened. This results in a relatively long work cycle. According to the invention, the length of the upper edge (40) of each laundry article (10) is measured, before it is spread out, in that the upper edge (40) is brought into a position in which it forms two sides of a triangle. Part lengths of the upper edge (40) can be calculated from this and, when added up, result in the total length of the upper edge (40). On the basis of the measured length of the upper edge (40), the clamps (18, 19; 20, 21;) can be moved into targeted positions in front of the feed conveyor (12), the upper edge (40) being stretched. This avoids an excessive stretching of the upper edge (40), whilst at the same time the clamps (18, 19; 20, 21) can be moved apart from one another at relatively high speeds until the upper edge (40) is stretched. <IMAGE>

Abstract: The treatment pin for stimulation of acupuncture points can be used in human medicine for acupuncture on human beings. It carries out the following three functions, in particular, using a control device concept: search for acupuncture points, electric acupuncture and laser acupuncture. The pin essentially comprises a treatment tip (2), two printed circuit boards (6, 7) and three switch elements (4, 5, 9). Two searching aids are provided for the search for acupuncture points. The treatment tip is functionally assigned a cannula (14) having a beam waveguide (15) on the inner wall, a light source (16), a cooling body (18) and a magnet (21). Each printed circuit board possesses an electronic circuit for evaluation and display of the the results of the search for acupuncture points and for control of the light source. The housing (1) surrounding the pin elements is composed of a circular cylindrical part and a circular truncated cone part whose generated surfaces merge into one another without a seam. The magnet is fixed to a cooling body which moves under a magnet-sensitive switch element on pressing-in of a spring-mounted treatment tip. A safety switch is connected to the magnet-sensitive switch element, release of the type of treatment preselected on the control device being provided after activation of the switch element.   <IMAGE>

Abstract: In a method of bleaching medium consistency pulp with ozone using a mixer (12), ozone containing gas and about 6-15% consistency pulp are fed (from 22) to the mixer, and then discharged in a first, preferably vertical, path (14, 16). The mixture of pulp and ozone moves in a first part of the vertical path a time period of about 1-5 seconds at a velocity of about 1-5 m/s so that the gas and pulp do not separate during movement in this first part, and the vast majority of the pulp brightening reaction between the ozone and pulp takes place. This is preferably accomplished by passing the mixture upwardly in a small diameter conduit (14) having a height of about 3-20 meters. Then the velocity of the pulp is slowed while still moving in the first path, preferably by feeding it directly to a much larger diameter (e. g. 1.5-10 times) conduit (16), so the height of the unit may be kept under 100 feet. The pulp flows in the large diameter conduit for about 0.5-5 minutes so that residual reactions take place. The pulp then flows into a second path (27) distinctly different from the first path.

Abstract: An article is provided comprising a plurality of straight spaced parallel extruded elements separated by a regularly undulated extruded element having an aspect ratio of at least about two, with undulations having opposed apexes on either side thereof, with apexes on one side of the undulated element being bonded to one of the parallel extruded elements and the apexes on the other side of the undulated element being bonded to the other of said parallel extruded elements. The article is formed by extruding a first filament-forming extrudable plastic mass to form a plurality of straight spaced continuous parallel elements, extruding (at a faster extrusion rate and between adjacent parallel element) a second filament-forming extrudable plastic mass to form an undulatable element which is thinner than it is wide to provide a cross-section with an aspect ratio of at least about two, causing the undulatable element to undulate in its thin dimension and to bond to the straight spaced continuous parallel elements, and changing or permitting the change of the formed, extruded plastic mass so that subsequent bonding will no longer occur and so that the elements have sufficient structural integrity to maintain their extruded bonded shape.
