Abstract: An apparatus for detecting and monitoring changes in the position of rotating shafts in which a light ray generally parallel to the shafts is directed to measurement positions (which are offset from each other by about 90.degree. in the circumferential direction of the shafts) to a rectangular prism, which reflects the ray to a ray receiver, which supplies signals, which change with any change in the position of the shafts. In known apparatus for making possible a continuous monitoring of the alignment condition of coaxial shafts, the ray source and the ray receiver are arranged on one shaft and a prism is arranged on the other. The signals of the ray receiver and the power supply thereof require the use of complex and unreliable transmission means between the rotating and stationary parts of the apparatus. According to the invention light rays (S and S'), come from two separate source-receiver pairs (2.sub.1,9.sub.1, and 2.sub.2 and 9.sub.

Abstract: An apparatus is proposed for detecting changes in the mutual position of two mutually spaced and separately mounted machines or parts thereof in relation to a given initial position in a rectangular spatial coordinate system. A high degree of functional capability and accuracy of measuring which at the same time ensuring a simple structure and high reliability is made possible. Furthermore, errors in alignment in the form of parallel and angular offset may be immediately seen. This is made possible by the use of a respective reflecting rectangular prism and a respective light transmitter for each of the three axial directions of the coordinate system, in which a mutual parallel offset and angular offset is to be detected. The reflecting and the light transmitters are mutually rigidly fitted on the machines or parts thereof.

Abstract: Device intended to determine whether two shafts arranged one behind the other are aligned or parallel or whether they are offset with a certain angle. The device employs a light beam S, S' and a mirror prism (6) or any other optical system and displays separately the alignment errors directly as a function of the parallel displacement and of the angular displacement. It may be used to align shafts and/or monitor permanently the alignment state of the shafts (3, 4).

Abstract: A multi-ply glove or mitt construction having a multi-ply shell and multi-ply selectively removable liner is provided with interengaging contacting surfaces. The shell is formed by an outer water repellant layer and an inner heat insulating layer, between which is sandwiched a relatively waterproof breathable layer. A slide layer is formed on the inner surface of the inner heat insulating layer. The insulating layer of the shell is preferrably formed of a lofting material such as down, DACRON or THINSULATE fiber, or the like natural or synthetic fibrous materials lending themselves to lofting. The slide layer faces the interior of the glove and is formed of a material providing a shiny surface by means of a non-brushed knit or woven synthetic such as nylon and/or similar sheet synthetic.

Abstract: A Coriolis-force mass flow meter is proposed, which is clamped at one side in a rigid mounting, has a tubular loop through which a test medium is flowing and which, relative to the mounting, is capable of oscillating itself about a particular axis of oscillation and can be given a rotary oscillation about a specified axis of rotation by an exciter system. In the state of the art, the axis of oscillation and the axis of rotation essentially coincide. In contrast to this, the special feature of the inventive flow meter consists therein that said axes have an angle that is significantly different from 0.degree., the axis of rotation having a directional component parallel to the plane of the tubular loop. In this way, a significant improvement in respect to signal generation is achieved.
