The object of the invention is an escapement gear wheel, wherein the shape of the teeth (21, 21', 22, 22') is chosen such that the straight line between the tip of a tooth (21, 21', 22, 22') and the centre of the escapement wheel (2) is fully enclosed within the escapement wheel (2). Further the object of the invention is an element rotation control mechanism, comprising an escapement gear wheel fixed at the element's axis of rotation and an anchor pivotably mounted at a distance less than half of the span of its arms from the escapement gear wheel (2). The anchor can come into contact with the escapement gear wheel with the first (11) or the second (12) arm. The span of the anchor's arms (1), the radius of the escapement wheel (2) and sized and the number of the teeth (21, 21', 22, 22') are chosen so that in the position of the escapement wheel (2), where one of the arms of the anchor (1) has a point of contact with the escapement wheel (2) located exactly at the bottom of the inter-tooth notch, the point of contact of the second arm of the anchor is located at the rear edge of a tooth (211, 211', 221, 221'). The object of the invention is also an element rotation control method, wherein the mechanism according to the invention is mounted to the element in the element's axis of rotation.

The object of the invention is a clamp mechanism, clamping on a tube made of elastic material, provided with a band clamped on a tube. Inside the tube (21), in the location where the band (23) clamps there is located a stiff element (22) having a diameter substantially corresponding to the inner diameter of the tube. The band (23) encompasses the tube (21) over the length of at least the half of its circumference and is connected to tensioning and releasing means (25, 27, 29). The object of the invention is also a system locking a multitubular manipulator, wherein a locking mechanism according to the invention is mounted on each of the tubes (41a, 41b, 41c). Further, the object of the invention is a method of operating a reconfigurable manipulator comprising curled strip tubes, characterised in that the manipulator is provided with a locking system according to the invention, which is released for reconfiguration of the manipulator and clamped for normal operation.

The object of the invention is a spragging mechanism for application in a tube. It is provided with a band and clamping means. The clamping means are arranged within the tube, outside of which the band is provided. The object of the invention is also a system for guiding bore head, provided with an spragging mechanism, head, means transferring the pressing force to the bore head, and also a curled tube fed from the drum into the wellbore. The curled tube (1) constitutes means transferring the pressing force, exerted by the pressing mechanism (2) via a mechanism releasably connected to the curled tube (1). The object of the invention is also a method of drilling a wellbore, wherein a bore head with an drill bit is lowered down the wellbore and pressed against its bottom, simultaneously inserting a tube into to wellbore. For pressing the head (9) with the drill bit (8) a tube (1) curled of strip (T1) drawn from a drum is used, wherein the pressing force is applied to the tube via a mechanism (11, 13, 2) releasably connected thereto.

The object of the invention is an electromagnetic drive comprising a core composed of at least two partially open sections. Each section partially surrounds the winding and is being closed by a closing element moveably connected to the core. This element is arranged so that in conditions of no current flow through the winding the core is partially not closed. The closing elements are arranged outside of the core and the winding and are connected to each other by a separating element made of material having lower magnetic permeability. The object of the invention is also a winding core composed of at least two partially open sections arranged along the axis of the core, characterized in that the openings of the core's sections are located in its substantially outer portion. Preferably, the core has axial symmetry and is equipped with a groove between sections adapted to accommodate the wire connecting the windings. Preferably, the separation of adjacent sections of the core corresponds to the length of a section. Furthermore, the object of the invention is a method of producing of electromagnetic drive comprising a partially open core, a winding and a moveable portion of the core, wherein the core is produced of at least two partially open sections, grooves adapted to accommodate the wire of the winding between sections are provided therein. The winding is wound in a continuous manner, with a single piece of wire, guiding the wire between sections in the grooves. The core is surrounded by a moveable hammer made of alternately arranged closing elements made of material having a high magnetic permeability and separating elements made of material having lower magnetic permeability, wherein the hammer is mounted to the core by means of means adapted to energy storing, so that in conditions of no current flow through winding the open sections of the core are only partially closed by the closing elements.

The present invention relates to a method for producing an interference image, wherein the input beam is divided into two beams at path of which beams at least one stationary reflective unit (ZS1,ZS2) is disposed and wherein each of said beams after reflection from said reflective unit is directed onto a movable reflective unit (ZR), at which the optical path difference between said first and said second beams is produced, and then both beams are reversed back and subjected to interference. A double-sided reflective (ZR) unit is used as a movable reflective unit, which is arranged at a route of said beams reflected from the stationary reflective units and onto which both beams are simultaneously directed, and wherein the difference of optical paths between said two beams is produced by means of linear displacement of said movable reflective unit (ZR) in the direction determined by the course of beams from its reflective surfaces so that the displacement of the movable reflective unit equal to x causes the difference in optical paths between said first and second beams equal to 4x. The invention provides also a system for producing an interference image and an interferometer with such system.

A tubular member (1) made of an elongated curling strip (1a) partly wound on a drum rotatable on the first axis, and partly curling around the second axis (H) into the tubular member (1). The first axis is perpendicular to the second axis (H). The tubular member (1) is extendable and retractable with rotation of the drum. The strip (1a) is provided with a number of protrusions (9) distributed on its surface along its length. The drive comprises a threaded element (3,7) rotatable around the second axis (H) and an abutment element (4,5) forming between each other a space adapted to accommodate a wall of the tubular member (1) in such a manner that the first side of the wall is in contact with the threaded element (3,7) and the second side of the wall is in contact with the abutment element (4,5).
