Abstract: For measuring sizes in a scanning measuring microscope a nominal magnification is selected so that an object image occupies a substantial part of a field of view, an actual magnification is calculated depending on a coordinate on a screen along the direction of measurement, the object is positioned on a microscope table so that a line of scanning coincides with a direction of measurement and scanned by an electron beam to obtain a function of a video signal, points are localized which correspond to left and right edges of the object on a curve, and a size of the object is determined from the coordinates of the left and right edges and the magnification of the microscope changing from one point to the other.

Abstract: A device for training cats to go on a toilet has a plurality of containers each having a hollow for accommodating a material onto which a cat urinate or defecate, the containers being inserted into one another so as to form an upper surface on which a cat can stand or sit, the containers being removable from one another so as to expose a throughgoing opening through which a cat can urinate or defecate, the containers being removable independently from one another so as to gradually expose throughgoing openings of different cross-sectional areas.

Abstract: A method of determining feed and radial forces has the steps of subdividing work materials into seven groups which are different from one another by Brinell hardness, for each group separately determining a feed force and radial force based on a tangential force in accordance with individual formula which is different from formulas for other groups, and also separately for a turning process and for a boring process. Also, a calculator is proposed which utilizes the inventive method.

Abstract: In a method of dynamic transporting of with a flow of object a carrying medium, action are applied to the carrying medium which are created in an action element during a process of conversion of an energy supplied to it, so that the flow of a carrying medium created thereby acts on the object for preforming a process of it transporting in a given direction, and a modulation of a value of the action is performed in the action element so that the flow of the carrying medium which is dynamically created moves with a given dynamic periodically changing sign-alternating acceleration during the process of transporting of the object.

Abstract: A method of commutation of current by separately controlled in each direction bi-directional switches of a matrix converter (MC) with at least three input phases, which allows to provide a safe step-by-step commutation of the current by MC switches without using information of the load current polarity and of the exact relation of mains voltages at the moment of step-by-step commutations beginning. It is suggested variants of implementing the proposed invention in the three phase-to-three phase MC with a space vector modulation (SVM) which provides the synthesis of space vectors of the output voltage and input current of zero and non-zero stationary vectors during each SVM cycle, with dividing the mains voltage period into six intervals with boundaries being determined by moments of input phase voltage polarity changing.

Abstract: A method of precision calibration of a microscope magnification with calculating a magnification scale as a quotient obtained when an image size of a test object viewed or collected with the microscope is divided by a true test object size, the methods comprising the steps of obtaining a magnification reference by taking a diffraction grating with a tested pitch value as the test object; distributing a brightness level between 30-70% amplitude in one of an image of the diffraction grating and a video signal obtained in the microscope; calculating a position of the video signal “center of mass” for each of formed “islands” of the brightness distribution; considering an average distance between neighboring “center of mass” as being a grating pitch in a microscope image of the object; and recognizing that a magnification scale of the microscope is a result of a division of an average pitch dimension by true grating pitch.

Abstract: A pendant necklace having a chain and a pendant. The pendant can convert from a first closed configuration, such as a Star of David, heart, or cross, to at least one open configuration such that multiple decorative looks are available. The pendant comprises at least three elements which are pivotably connected, and the pendant elements are prevented from pivoting about each other to a predetermined angle by pivot stops so that the open configuration does not inadvertently go to the closed configuration when in the open configuration.

Abstract: The invention is a dental articulator with an extended range of motion of the maxilla relative to the mandible The articulator includes a base and a mandibular assembly extending horizontally from that base. A mandibular plate is provided with a supporting structure, which is aligned with corresponding cavities in the mandibular base cast for easy removal and attachment. A base is further equipped with a vertical post slidingly positioned on a vertical shaft of that base. A maxillary assembly is retained on that post via a ball-and-socket arrangement and further via a horizontal shaft positioned in two semi-opened sockets and retained by a spring-biased pin. The maxillary assembly contains a plate supporting a removable base cast in a manner similar to that of the mandibular assembly. The articulator saves time and allows for easy positioning of the maxilla and mandible.
