Abstract: The invention provides a device for the axial delivery of fluidal mediums, which outer diameter is not or only insignificantly larger than the diameter of the fluid carrying pipe, which reduces to a large extent a shearing and vortexing of the fluid. A device for the axial delivery of fluidal mediums, having a tubular hollow body arrangement, in which delivery area, an impeller (9) with a blading, which can be rotated, is arranged and also has a fluid directional means. A motor (2), at least one impeller (9) which can be rotated, and at least one motor mounting (14) are arranged in a tubular hollow body (1) of the hollow body arrangement. The impeller (9) is connected axially force-fittingly and/or form-fittingly to the motor (2).

Abstract: An inertial sensor arrangement comprises a fiber gyro which responds to the horizontal component of the angular rate of the earth. A fiber coil of the fiber gyro is arranged at a positioning frame which is supported for rotation about a vertical axis relative to a housing. The positioning frame can be rotatably adjusted and mechanically locked into three fixed positions. Signals obtained thereby provide a measured value of the angle formed between a reference direction and north. Inclination sensors are provided for determining the inclination of the inertial sensor arrangement. The fiber coil inclusive of the positioning frame and two inclination sensors are mounted at a rigid sensor block which is connected to the housing in heat insulating manner.

Abstract: A process for hydrolyzing alkyl monohalides comprises using activated carbon impregnated with alkali metal hydroxide or alkaline earth metal hydroxide in the presence of water and converting the alkyl monohalides virtually quantitatively into the corresponding alcohols. Apparatus for carrying out the process comprises at least one, preferably two, especially three, reactors (2), especially tubular reactors. The process is also particularly useful for preparing alcohols.

Abstract: The invention provides a low cost apparatus assembly of an electrotechnical apparatus. The housing walls consist of plate-shaped elements. The dimensions and weight of the plate-shaped elements are considerably reduced as compared to the existing elements. The assembly has a housing wall with plate-shaped elements. At least part of the plate-shaped elements are synthetic plastic plates, which are metal-coated over a continuous surface area on one side. The metal-coated surfaces are interconnected electrically conductively. One or several of the metal-coated synthetic plastic plates are designed as printed circuit boards. They are provided with electrical and/or mechanical elements on the side which is not metal-coated. As the case may be, they are provided with strip conductors. The plate-shaped elements of metal, if present, are electrically conductively connected to the metal-coated surface of the synthetic plastic plates.

Abstract: To prevent the formation of a corona (2) in a known in-line color picture tube with an automatic-focusing deflection system and four grids (G1-G4), a rectangular opening is provided on the side of the second grid (G2) facing the first grid (G1). As a result, the luminous spot (1) formed by the electron beam at the center of the screen is converted to a vertical ellipse and the ratio of the axes of the lateral ellipses on the edge of the image is reduced, thus improving the sharpness of the edges. The openings (5) in the first grid (G1) are elongated in the in-line direction, in particular rectangular, the adjacent openings of the second grid (G2) are also rectangular and all the other openings in the other grids (G2, G3, G4) are circular. In this way, the ratio of the axes of the luminous elliptical spot (11) produced by the electron beam at the center of the screen is reduced without adversely affecting the sharpness of the edges.

Abstract: A gas ring-laser comprises a ceramic block containing a closed gas-filled channel (12) which extends along the sides of an equilateral triangle and forms a resonant cavity. An anode (64) and cathodes (76, 78) permit the creation of two gas discharges. With the aid of dielectric mirrors (26, 28 and 30), two light beams circulating in opposite directions are guided through the channel. In order to simplify construction, the ceramic block (10) consists of a glass ceramic which is produced from a green ceramic body by sintering. The mirrors (26, 28, 30) are located in adjustable metal holders (80, 82, 84) and fixed in the ceramic block (10) by means of glass solder (98). In addition, the other electrical connections for the electrodes in the cavity are sealed in place by glass solder. The invention also relates to a method for manufacturing such a gas ring-laser. The gas ring-laser may serve as an inertial sensor for measuring angular velocities by means of the Sagnac-effect.
