Abstract: Polycrystalline silicon is deposited in a film onto the surface of a substrate which has been carefully prepared to eliminate any defects or contaminants which could nucleate crystal growth on the substrate. The deposition is carried out by low pressure decomposition of silane at substantially 580 DEG  C. to cause a film of fine grained crystals of polysilicon to be formed having grain sizes averaging less than about 300 Angstroms after annealing. Such a film is very uniform and smooth, having a surface roughness less than about 100 Angstroms RMS. Annealing of the film and substrate at a low temperature results in a compressive strain in the field that decreases over the annealing time, annealing at high temperatures (e.g., over 1050 DEG  C.) yields substantially zero strain in the film, and annealing at intermediate temperatures (e.g., 650 DEG  C. to 950 DEG  C.) yields tensile strain at varying strain levels depending on the annealing temperature and time. Further processing of the polysilicon films and the substrate can yield isolated diaphragms of the polysilicon film which are supported only at edges by the substrate and which have substantial lateral dimensions, e.g., 1 cm by 1 cm. Such that structures can be used as pressure sensor diaphragms, X-ray masks, and optical filters, and can be provided with holes of varying sizes, shape and number, which can serve as X-ray mask patterns. The diaphragms can be provided with numerous holes of uniform size and spacing which allows the diaphragms to be used as filters in ultrafiltration applications.

Abstract: Un chalumeau de coupage au jet d'arc plasma, en particulier un chalumeau qui fonctionne dans la fourchette 0 à 200 ampères, comporte un élément de protection (38) fixé en son extrémité inférieure, à proximité de la pièce à usiner (26), ce qui empêche le métal fondu d'éclabousser une buse (16) du chalumeau. Ledit élément de protection est électriquement isolé, de préférence en étant fixé sur un anneau d'isolation (22), qui est à son tour fixé sur un chhapeau (20) vissé sur le corps du chalumeau. Un courant de gaz secondaire de refoidissement, qui passe à travers le chalumeau, traverse l'espace qui sépare la buse (16) de l'élément de protection (38). Des ouvertures d'évacuation (44) dans l'élément de protection (38) permettent un débit accru, le reste du courant gazeux circulant à une vitesse déterminée par la taille de l'orifice de sortie (42) de l'élément de protection (38) de manière à stabiliser l'arc plasma. Des ouvertures chanfreinées (54) sur le trajet du courant de gaz secondaire font tournoyer le courant de gaz, ce qui améliore la qualité de la coupe.

Abstract: L'invention concerne une glissière à rail de sécurité comportant une pluralité de paires (10, 11) de rails de sécurité dont les extrémités amont sont fixées à des pieux (14-18) opposés latéraux pouvant être rompus, des boulons d'assemblage (40) reliant les extrémités se chevauchant des rails adjacents et une pluralité de fentes (42, 43) espacées prévues dans chaque extrémité alignée avec chaque boulon d'assemblage. Un véhicule heurtant le nez de la glissière provoque la fragmentation du matériau du rail entre les fentes. Le pieu (13) du nez comporte une partie à encoche située au dessus du sol, le haut du second pieu (14) est relié par un câble (32) au pied dudit pieu du nez. La partie (19) de nez se compose d'une partie courbée (20) et d'une paire de parties latérales (22, 23). La résistance télescopique se trouve réduite par le fait que les boulons d'assemblage passent au niveau de l'extrémité du rail chevauchant, par une fente (42) sensiblement plus longue que les fentes adjacentes (43). Afin d'augmenter progressivement la résistance télescopique, on augmente graduellement l'espacement des fentes.

Abstract: The process for establishing the pressure-diameter relation of an artery uses the measurement results from a non-invasive sensor (3) determining the diameter of the artery, for example the humeral artery, and a non-invasive sensor (4) determining the blood pressure, for example at the end of a finger. The measurement positions being separated by a distance  DELTA x, the process envisages the correction of the pressure measurements as if these measurements had been taken at the position where the diameter measurements are carried out. The process additionally envisages a correction taking account of the mechanical properties of the artery, defined by parameters  alpha , beta , gamma ,..., which are calculated, if necessary by successive iterations, until the pressure-diameter curve appears to be free of any measurement artifice (hysteresis). The pressure-diameter relation makes it possible to calculate the mechanical properties of the artery using, in particular, curves of compliance and speed of propagation as a function of the pressure. <IMAGE>

Abstract: In order to achieve optimum combustion with low soot formation and a low concentration of toxic exhaust gas constituents, a combustion chamber in the piston of a direct injection diesel engine is proposed, which has a cylindrical section (1) with a diameter of 0.4 to 0.45 D and a height of 0.02 to 0.025 D, where the outside diameter D of the piston serves as reference variable, its bottom edge (3) being at a distance (4) of 0.03 to 0.035 D from the end face (5) of the piston. An outer section (6) widening conically towards the end face (5) of the piston and the generating lines of which form an angle ( alpha ) of 10 DEG to 12 DEG  with the end face (5) of the piston adjoins the upper edge of the cylindrical section (1). From the bottom edge (3) of the cylindrical section (1) there extends an inner section, widening conically in the direction of the base (9) of the piston, the generating lines of which form an angle ( beta ) of 55 DEG  to 60 DEG  with the end face (5) of the piston or planes parallel to this. The inner section (7) passes via a continuous flowing transitional section (8) into the base (9), which has the form of the surface of a sphere with a radius of 1.45 to 1.5 D. The distance (10) of the base (9) from the end face (5) of the piston along the central axis (11) of the combustion chamber is 0.25 to 0.28 D. <IMAGE>

Abstract: To provide perforations on the webs (4) of spacer frames (1) formed from hollow sections (2), the said webs facing the pane interspace (5) of an insulated glazing unit, the region of perforation is first of all deep drawn in the direction of the inside of the section (2) and a hole is then punched in the deepest point of the deformation (7a) thereby obtained. This deep-drawn region is then rolled in such a way that the depth of this deep drawing is somewhat reduced and the perforation (6a) is thereby pressed to in a dust-tight manner. This can be achieved in a simple manner with a roll (9) having a circumferential groove (10), giving rise overall to a spacer frame (1) which has pressed-to openings (6) at the deepest - or highest - point of knob-shaped depressions (7) on its webs (4) facing the pane interspace (5), with the result that pulverised or crushed desiccant dust is prevented from falling out not only by the reduction in the cross-section of the openings (6) when pressed to, but also by their raised position relative to the upper horizontal web (4) of the hollow section (2).

Abstract: In a direct-current arc furnace, the arc is deflected under the influence of the high-current lines (18), which run below the furnace vessel, in the direction away from the power supply device (19). This leads to thermal overloading of a part of the furnace vessel wall. If the lining layers are constructed such that, in a first sector (21) which opens towards the power supply device (19), they are formed from a material having a lower specific conductivity than the lining layer in the second sector (22), the arc burns symmetrically again. A lining layer which is inhomogeneous in this sense can furthermore be used for deliberate deflection of the arc.

Filed: 1990-12-17
Abstract: A pulverising or grinding mill in which steel balls 1 roll on a circular path intermediate a rotating lower annular track 7 and a fixed upper track 2, the lower track 7 resting on a support table 4 having a drive 5. As shown on the right hand side of the drawing, an underface 10 of the lower ring 7 is formed with a relieved portion 14 and an annular landing face 9. The annular landing face is machined with a slight bias toward removing metal from a radially inner portion so that the face 9 is of slightly frusto-conical form. In an unloaded condition, the lower ring is supported at a radially outer edge portion on the support table 4. On applying a load and driving the table, the table deflects slightly and support of the ring 7 is effected at a radially inner annular face of contact substantially coincident with the loading vector. This substantially avoids the generation of a radial bending moment across the lower ring 7 due to the avoidance of an offset reaction to the loading. Edge portions 13, 18 of the lower ring 7 are of rounded, merging, form to avoid localised stress concentrations from any residual radial bending moments. The tracks 20, 8 in the upper and lower rings 2, 7 are of a slightly larger effective radius of curvature than the steel balls 1 to permit a slight osciallation in the path of the balls 1 without the force vector moving outside the annular face of contact.
