Window construction, intended for placing in a door, panel or wall, in particular of so-called sandwich construction, which window construction comprises an outer part and an inner part, each composed of a window of transparent material, merging into a peripheral edge provided with means for fastening the outer or inner part, while annular coverings (17, 18) are present, separate from the peripheral edge (5, 6) and the window (3, 4), in order to conceal the inside of the panel or the wall from view. Said annular coverings are each quadrilaterally symmetrical, but have mutually differing dimensions, so that they can be slid into each other during the fitting.

Process for the continuous analysis of the composition of gases, by means of a measuring head for determining the flow velocity and analysis equipment which is placed a distance away from the measuring head and is connected thereto by a sample line, a calibration gas being fed to the sample line at the measuring head, by means of which the transit time of the gases is determined, and by means of this transit time a phase shift is introduced during determining of the connection between the velocity of flow and the composition. According to the invention a series of calibration gas impulses are fed from the equipment, and the average transit time of the gases in the conditions prevailing locally at that moment is determined therewith, for the essentially continuous determination of the connection between the flow velocity and the composition. Device for carrying out the process comprising a measuring head (5) and analysis equipment (1) for determining the composition of the gases, provided with a source (7) of calibration gas in the analysis equipment (1), a calibration gas line (9) connected (at 11) to the sample line a short distance from the suction aperture thereof with the measuring head (5), means for maintaining the calibration gas under pressure, and means for periodically opening a valve in the calibration gas line, and means (12) for determining the transit time of the calibration gas impulses through the sample line.

The invention relates to plasters and bandages, and more generally to all self-adhesive and non-adhesive products for medical purposes, intended to be applied to and to remain visible for shorter or longer time periods on the human skin. The material, or at least the surface thereof which, in use, will be visible, is coloured and the colour has been chosen from the group comprising brown and yellow in all shades and from light to dark, black, and optical white. In methods of manufacturing the products, one may either use coloured material or colouring treatment, the colour of which has been chosen from the group mentioned above.

A flowmeter for gases, comprising a rotor (11) between two stators (3,3′) which consist of deflection blades, optical means being provided to detect the rotation of the rotor and convert it into an electrical output signal. Each of the detector blades of the stators has a curved course between an inflow edge (7), where the blade face from the hub (9) to the periphery runs substantially axially, and an outflow edge (8), where the blade forms an angle with the axial direction which angle depends on the distance from the hub. Preferably the blade face is at least partially (18) formed by a circular cylindrical face (15/17), the central axis (14/14′) of said cylinder intersecting the central axis (12) of the stator at an angle differing from 90° at such a distance that the central axis of the stator lies in a tangent plane to the cylinder, and a flat face part (22), passing through the central axis (12) of the stator, connects to the circular cylindrical part (18) of the stator face up to the inflow edge (7), the axial measurement of said flat face part (22) decreasing from the hub (9) to the peripheral edge (4). The flowmeter can be cast and presents an excellent reproducibility of its features between individual units, in the two positions, and it has a great dynamic range.

Movable beer faucet of the type which is adapted to be used independent of electric power supply, comprising an insulating jacket into which a container filled with beer can be placed, a detachable beer tap with a connection for a carbon dioxide container and a faucet tap. The insulating jacket (2) is open at the bottom, the bottom fitting on a base (7) of insulating material onto which the beer-filled container (5) is to be placed, the top (4) being closed, except for a bunghole (3) for the beer tap. A separate tapping table (14) is present, provided with a bore (18) for fitting a tapping column (15) and with a collecting cavity (19) over which a perforated tapping plate (20) is placed in the tap surface (16). Preferably the tapping table (14) is provided with one or two other cavities (21, 23) for a washing basin and/or a rinsing basin.
摘要:
Method of analysing geophones, comprising sending electric currents through the geophones and deriving desired parameters from the output voltages and/or currents. One string of geophones is used as a reference which compensates influences of temperature. A calibration measurement can be carried out on a precision ohmic resistor. Applied on geophones which have a high damping a negative resistance network is coupled in parallel to the geophone terminals. The pulse response test is used to derive sensitivity, damping and resonance frequency, and to calculate the DC resistance. Distortion tests are carried out on the basis of sine wave currents sent through the geophone(s). The invention also includes an apparatus for performing the method. The apparatus is advantageously microprogram-based.
