Patent EP-0423798-A1 (EP)
Inventor: DAFTARY FEREIDOUN
IPC: A61C8/00
Filed: 1990-10-18
Abstract: A system and method is provided for implanting tooth analogues in the jawbone resulting in aesthetically and functionally desirable gingival tissue contours after restoration. The system permits modification and adaptation of the tooth analogue to meet intraoral demands in a manner similar to that used in the preparation and restoration of natural teeth. The system comprises a standard fixture (12) and cover screw passed through opened gingival tissue and implanted in the jawbone. After the ossointegration of the fixture, the gingiva is reopened, the cover screw removed and a healing cap (30) having a predetermined contour, is attached to the fixture. The reopened gingiva re-heals in a shape determined by the contour of the healing cap. The healing cap is then removed and replaced by an abutment (4,6,9) having an emergence profile matching that of the healing cap. An immediate snug fit between the gingival tissues and the abutment is thereby provided at the time of connection of the abutment to the fixture. A crown (2) is removably attached to the abutment by a screw (90) extending through the side of the crown into the abutment. An improved version of the healing cap is a healing cap created in two portions (138,140) so that one portion (138) around which gingiva tissue regrows remains in the patient and only a second upper portion is removed (140), and an improved abutment (204) which is engagable with the portion of the healing cap left in the patient is used for the abutment about which the crown is removably attached.

Abstract: A process for producing a multilayer polytetrafluoroethylene porous membrane is disclosed, which process comprises at least two layers having different average pore diameters, the process comprising the steps of: filling the inside of a cylinder of an extruding mold distinctively with at least two kinds of polytetrafluoroethylene fine powders with each of which a liquid lubricant has been mixed; paste-extruding the powders to obtain a multilayer extrudate, which is then optionally rolled; removing the liquid lubricant from the multilayer extrudate or the rolled multilayer extrudate to obtain an unsintered multilayer structure; subsequently heating the unsintered multilayer structure at a temperature not lower than the melting point of sintered polytetrafluoroethylene to obtain a semisintered multilayer structure; and then stretching the semisintered multilayer structure at least monoaxially. A semisintered polytetrafluoroethylene multilayer structure capable of being used as an intermediate material for the above process is also disclosed.

Abstract: Die Erfindung betrifft ein Verfahren und eine Mahlanlage zur Zerkleinerung von sprödem Mahlgut, wobei vorzerkleinertes Gut einer ersten Mahlstufe als Frischgut der zweiten Mühle (3) einer zweiten Mahlstufe zugeführt und aus dieser zweiten Mahlstufe Fertiggut abgezogen wird und wobei die Aufgabegutmenge dieser zweiten Mühle (3) bei sich ändernder Fertiggutmenge durch Änderung der Frischgutmenge konstantgeregelt wird. Diese erste Mahlstufe enthält einen Windsichter (2), aus dem das Feingut als Frischgut der zweiten Mühle (3) aufgegeben wird. Eine Änderung der Frischgutmenge für die zweite Mahlstufe wird dadurch konstantgeregelt, daß die Sichtfeinheit des Sichters (2) dieser ersten Mahlstufe entsprechend verändert wird. Hierdurch wird eine zuverlässige, feinfühlige Anpassung der Gesamtdurchsatzmenge der zweiten Mühle (3) bei sich änderndem Fertiggutabzug aus der zweiten Mahlstufe mit relativ einfachen Mitteln erreicht. <IMAGE>

Abstract: A liquid float gauge assembly (12) for a fluid reservoir (10) includes a float (30) having a magnet (35) in a vertical tube (20) having an adjacent vertically spaced reed switch (41) arrangement. The float (30) is capsule shaped with an extended round cylindrical portion (31) having rounded axial ends (32,33); and the magnet (35) tends to be attracted to the closest reed switch (41) to bias the float (30) against the inner surface of the tube (20). The tube (20) has a horizontally cross-sectional shape substantially matching and just larger than an axial section of the float (30) so that the float (30) has a stable floating orientation with a horizontal axis and is capable of rolling during vertical movement within the tube (20) to reduce friction due to liquid surface tension between the float (30) and the tube (20). The magnet (35) has poles at axially opposing ends (36,37) thereof within the float (30) and a circumferentially consistent spacing relative to the outer surface of the float (30) so as to provide a substantially non-varying magnetic field strength radially adjacent the float (30) as the float (30) rolls.

Abstract: A turbo machine including a movable member and a stationary member which has a coating layer disposed adjacent to the movable member, formed by flame spray coating and including at least one selected from the group consisting of hexagonal system boron nitride and ceric oxide. Since the coating layer is easily machined by the movable member, the coating layer comes to have a surface generated by machining the movable member and the clearance between the movable member and the stationary member is made zero substantially (0) even at a high temperature. Thus, the efficiency of the turbo machine has improved. In addition, since the coating layer has a high thermal shock resistance, the durability of the apparatus has improved also.

Abstract: To fix two plates (3, 4) on the cylinder formed by a shell (1) or by a plate cylinder of an intaglio printing machine, two axial grooves (2) are formed on this cylinder, in such a way that the plane of one of the lateral faces of each groove (2) is inclined relative to the axis of the cylinder. Welded to the concave face of the two ends of each plate (3, 4) is a batten (5, 6), of which the face adjacent to the end of the plate is perpendicular to said plate. The edge of each plate (3, 4) projecting beyond the corresponding batten (5, 6) is then cut off in such a way that the edge of the plate forms with the face of the batten a continuous surface and that the sum of the lengths of the plates is equal to the length of the periphery of the cylinder. Subsequently, the plates are arranged on the cylinder (1) by introducing the adjacent battens (5, 6) into a groove (2), and the free space of the groove is filled by a wedge-shaped bar (7) for tensioning the plates and for obtaining a butt joint.

Abstract: A method of extending the life of components of newly constructed nuclear reactors or newly replaced components of existing reactors is taught. The method involves forming a deposit on the surfaces of metallic elements of the nuclear containment, as well as on the surfaces of internal components which are exposed to high-temperature, high-pressure water and steam. The deposit formed is a deposit of at least one member of the platinum group of metals. The deposit is formed by any of a number of conventional methods such as electroless deposition, electrochemical deposition, chemical vapor deposition, sputtering or other conventional method. In operation, this deposit facilitates the combination of hydrogen and oxygen to form water and thereby aids in reducing the electrochemical corrosion potential of the system to values below a critical potential range that prevents stress corrosion cracking.

Abstract: In a method for transmitting data from a central station to a plurality of data stations via a multipoint connection according to a prescribed transmission protocol, every data station has an address allocated to it under which it receives data and outputs messages to the central station. When at least two data stations request data from the central station, the central station (Z) selects one of the data stations that request data and communicates the address of the selected data station (K1) to the further data station (K2, K3, Kn). In response thereto, the latter modifies its address to the address of the selected data station (K1). The central station (Z) transmits data to the selected data station (K1) that is also received by the further data station (K2, K3, Kn), whereby the transmission protocol is only processed between the central station (Z) and the selected data station (K1) during the data transmission. After the conclusion of the data transmission, the further data station (K2, K3, Kn) resets its address.
