Abstract: An endoscope is provided with a processing tool (24) arranged at its distal end. The processing tool can be moved by a mobile hollow shaft (12) extending in the longitudinal direction (X) of the endoscope. An endoscope optic (14) is arranged inside the mobile hollow shaft (12).

Abstract: A technoscope for examining surfaces in confined spaces includes a shank on whose distal end a pivotable arm with a measuring device is arranged, which may be pivoted from a first position in which the arm extends in the longitudinal direction of the shank into a second position in which the arm extends bent at an angle to the longitudinal axis of the shank.

Abstract: An endoscope comprises a hollow shank, optic viewing means positioned in the hollow shank for observing a body cavity, and a separate adjustable instrument channel which is axially, slidably arranged in an internal guiding region of the hollow shank. The instrument channel has a flexible curvature section and a laterally running end section with an end portion that is pivotably and articulably mounted in a radial passage in the distal circumferential wall region of the hollow shank. Sliding the instrument channel axially in the hollow shank results in flexing of the curvature section and pivoting of the end portion, such that an auxiliary instrument provided in the instrument channel is laterally deflected when guided through the hollow shank.

Abstract: The present invention relates to an instrument such as a technoscope, for machining the surfaces of for example, engine blades in normally inaccessible cavities, having a machining tool able to be simultaneously observed at the machining location with an optic, comprising an instrument shank to which a head is distally coupled, said head carrying the tool and being pivotable relative to the longitudinal axis of the instrument shank. In order to create the possibility of being able to measure damage to the surface to be machined with this instrument, a measuring tool with a measuring template is attachable to the instrument head, and with this instrument head, is pivotable into the field of view of the optic. The measuring tool may be attached to the head of the instrument in a simple manner instead of a machining tool. However the measuring template may also be arranged directly at the machining tool.

Abstract: The present invention relates to a device for fastening a rotatory drivable tool to the head of a technoscope by screwing a tool holder provided at the proximal side end of the tool to the distal end of the shank of a drive spindle. To secure undesired detaching of the tool from the technoscope, the tool holder is additionally screwed onto and against a cylinder sleeve which is run through by the shank of the drive spindle and rotatably mounted in the technoscope head.

Abstract: An endoscope is disclosed which is flexible at least section-wise and comprises at least one picture guide with an objective arranged at the distal side, and an eyepiece as well as a light guide arranged at the proximal side and a shank surrounding these components. The shank is made from a superelastic material and is dimensioned such that the endoscope is automatically restored to its original shape.

Abstract: An instrument is provided for working of surfaces of parts inside engineered cavities by means of a tool, with the possibility of simultaneous viewing of the site of the working operation. The instrument, also called a borescope, has a tool that can be placed at the end of the instrument shaft and be driven in a rotating fashion by means of a belt that goes around a drive pulley at one end and, at the other end, around a pulley secured to a shaft that is mounted in a head that carries the tool and can swivel. In its operating position, the head is turned at an angle of 90.degree. to the shaft, whereby the pulleys lie in the same plane. At other angles, the belt is prevented from jumping out of the pulley.

Abstract: A technoscope for checking for damage, especially a crack, in a surface of a cavity in a technical component, is arranged not only to establish the area of damage but also to measure the depth of a damaged area. To this end, the technoscope has a measuring attachment comprising a measuring probe with two electrodes for straddling the damaged area, and being supported in the cavity by a support element. The depth of the damaged area is measured by means of a depth measuring instrument sensitive to the disturbance of current flow between the electrodes, and the potential difference resulting therefrom.

Abstract: A technoscope for determining the extent of damage to objects includes an endoscope which is displaceable with a fixed stroke in a guide with a point of the object being coincided with a scale at both terminal positions of the stroke, the scale being in the form of a transparent screen plate which is displaceable transversely of the axis of the endoscope, a first measurement value transmitter for mechanically detecting the displacement value of the endoscope and for converting the same into an electrical signal being connected to a calculator, and a distal prism for lateral viewing being pivotally displaceable in the endoscope with the angle of pivotal displacement being mechanically detected and converted into an electrical signal which is transmitted to the calculator.

Abstract: A technoscope for internal inspection of plant such as special aircraft power units equipped with non-circular, preferably cornered (e.g. square) wall ports comprises a rigid first metal guide shaft of non-circular cross-section insertible into one of the wall ports and having a lateral distal outlet guide, and a guiding element which passes through said first guide shaft and has a flexible distal portion, an intermediate portion whose cross-section matches that of the first guide shaft and a proximal control system for controlled deflection of said flexible distal end. The guiding element is used to guide a flexible endoscope shaft to the desired site within the plant to be inspected.

Abstract: A portable measuring device for testing optical systems of an endoscope consisting of a base plate, a rail with a longitudinally extending V groove for receiving a portion of the endoscope being mounted to extend parallel to the plate on a carriage movable at right angles to the groove. The device includes a vertical shaft mounted on the plate and terminating at one end in a conical point and the shaft carries at least one extension arm which is mounted to pivot in a plane parallel to the base plate. Each arm adjustably supports a measuring disk which can have its height above the plate changed or its distance from the shaft changed.
