Granted: 2020-06-01
Abstract: FIELD: transportation. 
     SUBSTANCE: invention relates to pipeline transport and can be used in construction and repair of pipelines with internal anticorrosive coating in industries and in municipal services. Method of welding pipelines with internal anticorrosive coating comprises preparation for welding of edges and inner surfaces of connected ends of pipes by cleaning from dust and contaminants and degreasing with acetone of internal cavities of pipes in the zone of ends at depth of 100–200 mm, thereafter, an internal protection sleeve of the welded joint of pipelines with an inner anticorrosive coating is placed inside one of the connected pipes, comprising a cylindrical housing with flared ends and an internal anticorrosion coating, with radial stops made in the form of annular projections made near the ends of the housing, which outer diameter is equal to inner diameter of connected pipes. On outer surface of said housing there is heat-insulating material, in the middle there are external stops, and between radial stops above heat-insulating material there is a layer of thermoactive material, which is evenly distributed throughout the radius with the height of the radial stops, between the said stops and flared ends of the bushing there are elastic collars the outer diameter of which exceeds the internal diameter of the pipeline. Thermoactive material used is a composition consisting of an epoxy-polyester mixture which, when heated, is polymerised, and a gas-forming agent which enables to color the inner surface of the pipes by thermal action, after which the pipes are brought to rest against the stop of the pipe ends into external stops and leveled, after which the attached pipes are clasped and external stops are removed, then the root seam is welded, avoiding at the same time metal burns and the electrode or welding wire pumping into the pipe cavity, section of welded seam at 10–15 mm above semicircle is left to release thermoactive material during its thermal expansion and released gases, filling of the seam is performed immediately after the passage of the root seam until the thermoactive material leaves the non-welded section, when the thermoactive material is released, the welding process is stopped, waiting for termination of output of thermoactive material and gases, released material is removed from non-welded section and welding filler is continued, after termination of released gases, root is welded and filler seam is finished, and in case of non-availability of thermoactive material from non-welded part of pipe seam, pipes are uniformly heated in area of installed bush by 200–240 mm with gas burner along entire surface from bottom to top up to moment of thermoactive material output from unprocessed section of welded seam, after that it is cleaned and brewed. 
     EFFECT: method is characterized by simplicity and speed of pipe butt welding.

Abstract: FIELD: medicine. 
     SUBSTANCE: invention relates to medicine, namely to methods for creating an individual profile of gum eruption during dental implantation. The method includes virtual modeling of an individual gingiva former and an impression coping before the implant is installed. Computed tomography of the maxillofacial area, scanning of the patient's jaw model, and data alignment by reference points are performed. In a computer program, a virtual installation of a missing tooth or a group of teeth takes place. The surgical navigation template is simulated in a computer program. In the CAD program, the gingival cuff former is simulated by separating the subgingival part from a virtually installed tooth on a titanium base. In this program, an individual impression transfer is simulated by simulating a retention element on a virtual gingival cuff former. The physical fabrication of a surgical navigation template, an individual gingival cuff former and an individual impression transfer is performed. The titanium base is connected to the fabricated gingiva former. Clinical placement of a dental implant is performed using a surgical navigation template. A one-stage clinical installation of an individual gingival cuff former is performed. After the osseointegration period, the fixing screw is unscrewed and the gingival cuff former is removed, the impression is taken using an individual impression coping. The model of the patient's jaw is cast with the position of the dental implant and the individually formed gingival eruption profile. Modeling and physical fabrication of the artificial restoration on the implant is carried out on the basis of individually formed gingival contours. 
     EFFECT: reduction of terms from the moment of osseointegration of the implant to the beginning of its prosthetics.

In this case, the template overlaps the teeth from the vestibular side at the level of the clinical equators and completely overlaps the palate. The template has an opening of the shape determined at the stage of clinical planning of the operation corresponding to the geometry of the operating field. The thickness of the walls of the guide template along the contour of the hole corresponds to the thickness of the patient's mucosa, determined from the data of computed tomography and scanning of teeth, and is made with the possibility of adjusting the depth of immersion of the scalpel blade in the donor zone. 
     EFFECT: template allows providing a perpendicular direction of the scalpel during the extraction of the gingival graft at a given depth with a certain shape, to reduce trauma, and also to shorten the time of surgical intervention.

Abstract: An ink fountain including a frame defining a horizontal slot adjacent the fountain roller. Arranged side by side in the slot is a metering assembly in the form of a series of flat slides each having a cam assembly at its rear end for adjusting the position of the slide with respect to the fountain roller thereby to meter ink in predetermined thickness in respective zones. Each slide is formed of a body having secured thereto a rectangular tip portion formed of resilient plastic.

Title: Getastetes Störfilter in einem Fernsehempfänger
IPC: H04N5/21

Granted: 1985-03-14
Abstract: Ein Videosignalkanal in einem Fernsehempfänger enthält ein getastetes Filter (40), dem eine getastete automatische Helligkeitsregelschaltung zur Einstellung eines gewünschten Schwarz- oder Austastpegels für das Videosignal folgt. Die Helligkeitsregelschaltung arbeitet während der Austastintervalle (T ↓B) des Videosignals, wobei es den Austastpegel des Videosignals abfühlt und ein Regelsignal ableitet, das zur Aufrechterhaltung des gewünschten Austastpegels benutzt wird. Das Filter weist eine Hochpaßfilterschaltung (45) auf, die während der Bildintervalle zur Aufhebung der Filterwirkung abgekoppelt wird, jedoch während der Austastintervalle an den Videokanal angekoppelt wird, um hochfrequente Signale einschließlich eventuell vorhandener Zerstörungen im Videokanal während der Austastintervalle zu unterdrücken. Der abgefühlte Austastpegel und die Regelspannung sind daher unbeeinflußt durch Störungskomponenten, welche andernfalls das Regelsignal und damit den Betrieb der Helligkeitsregelschaltung beeinträchtigen würden.
