Abstract: A propeller for ship propulsion consists of trapezoidal helically shaped wings (3) which are arranged planetarily about its axis of rotation advancing axially in a screwing mode. The wings of the propeller, constituting a portion of a complete spiral of a screw, are disposed at a certain distance (radius) from their axis of rotation, on the same or on a different perpendicular or transverse plane to the axis of the hub (1) and at the same or a different radius, being mounted on the hub by means of arms (6). The wings (3) tend to momentarily (instantaneously) immobilize a mass of water in which the propeller is operating, thus attaining a support on a solid and steady (or almost solid and steady) body/mass and consequently causing axial advance in a screw-like manner like a worm screw. <IMAGE>

Abstract: One group of eight electrical leads (F) is on an outer cylindrical surface, the radius of which is equal to around 0.2 wavelengths calculated at the centre of the lower half of the area frequency range. The leads are distributed parallel to each other, and pref. evenly, with a length slightly more than half a wavelength (a quarter wavelength in the case of a monopole). The remaining leads (G) are fitted on an inner cylindrical surface, the radius of which is also equal to approx. 0.2 wavelengths, but calculated at the centre of the upper half of the aerial (A) frequency range. The length of each lead in this second group is identical to that in the first group. All leads are divided at one or more points, division being capable of being short-circuited using a change-over device. An alternative version has the straight electrical leads fitted parallel to each other on only a part of the cylindrical surfaces corresp. to a 30 degree sector. The leads, using support arms and a rotator may be rotated around the central axis of the aerial from one angular position to another. Both the change-over device and the rotator may be remote-controlled from a radio receiver. (Provisional basic advised week 86/44)

Date Dec. 18, 1986.A device for the production of a locking or braking effect between two elements, such as a shaft (20) and a hub (21), which display two concentric, cylindrical surfaces, which device includes a sleeve, made in one piece, for axial insertion between the surfaces. The sleeve is circumferentially divided into sleeve sections, which are separated by, at least partially, axially directed rows of holes in the body wall of the sleeve, and which are connected to each other by bridges, formed of the remaining wall material between the holes in the said rows. The body wall is provided with weak zones, designed to, through compression, project radially inwards and outwards into engagement with the said surfaces in order to achieve the locking and braking effect. Circumferentially adjacent sleeve sections are designed to be displaced axially in relation to each other, in order to produce compressive forces upon the bridges, which thereby undergo such a change of position and/or form that the forces which produce the compression of the weak zones are then produced in the sleeve.

Abstract: A device for making a spun fleece has a spinning nozzle or spinneret system, a cooling shaft, a stretching gap, a diffuser shaft, a continuously moving fleece receiving conveyor and a device for feeding process air and for pulling or removing outflowing air through the fleece receiving conveyor. The cooling shaft has a shaft wall provided with a plurality of air orifices. Because of that process air required for the cooling is fed into the cooling shaft. The air flow at least partially is pulled through the fleece receiving conveyor and the spun fleece formed by the deposited endless filament loops. The deposited length of the endless filament loops is measured over the spun fleece width in the finished fleece. The measured value is compared with a predetermined set value. On deviation of the measured value from the set value the setting angles of the air control flaps pivotable about a horizontal axis which are located at the entrance of the stretching gap are changed. On a positive deviation of the measured value of the thickness from the set value the setting angles are decreased (deposited length larger than the set value).

Abstract: When a predetermined level of relative movement between the lines (4) and the platform is reached, a brake device (11) is initiated and activated which acts on the lines. This device takes the form of a clamp arrangement (12, 13) comprising two rails arranged parallel to and movable to and from one another. Each rail has a track facing the lines. In conjunction with the two rails functions a two arm system (14, 15) which when it moves in one direction causes the rails to move towards each other and clamp the lines. When it moves in the opposite direction, the rails are moved apart. First and second hook components (16, 17) are fitted to the clamp arrangement, holding it in an inactive position. A further device (20) can disengage the hook components, allowing the rails to clamp against the lines (4).

Abstract: The method determines the angular offset between axial asymmetries, in particular between optically inhomogeneous regions in optically transparent bodies, such as stress concentration zones (7) of optical PM fibres or fibre cores (3) of optical twin core fibres (1), located in arbitrary angular start positions. The method includes illuminating the end of the fibres during their rotations to different angular positions around their longitudinal axes. For different angular positions the difference (h) is then determined between light, which has passed through the fibre end and in its position corresponds to the central part of the fibre, and light, which has passed through the fibre end and in its position corresponds to the region of the fibre located immediately outside the central part. These differences (h), considered as junctions of the rotation angle, constitute curves for the fibre ends. - The curves are compared and are translated in a parallel way to a new angular position, where a max. agreement is obtained in the shape of the curves. The angle between the curves in this angular position gives the angular offset between e.g. the plane (8,8'') through the stress zones (7) or the fibre cores (3) in their start positions and this angle is used for rotating the fibre ends, so that these planes and thus the stress zones or the fibre cores in the fibre ends will be aligned with each other.

Abstract: The invention is directed to a method for periodically clock driving a through-flow control valve between a first position wherein the valve is closed and a second position wherein the control valve is open to pass a flow of fluid therethrough. The valve is driven by a drive signal having a period duration and the valve opens in response to the drive signal only after a delay time (tv) has elapsed. In the method, the period duration of the drive signal is changed, and a reaction of a variable, which is operatively coupled to the flow, is detected. A value of the delay time (tv) is utilized when forming the drive signals and the value of the delay time (tv) is changed in dependence upon the detected reaction of the variable.
