Abstract: The device comprises a movable carrier, and a probe which is placed in or on the liq. under examination. The probe is connected to the carrier by a union which, on the one hand, tends to promote movement of the carrier, and on the other hand permits relative movement between probe and carrier. An indicator provides data concerning the positions of the carrier and the probe, and therefore the viscosity-dependent resistance which the liq. exerts on the probe when the carrier moves. The rotatable union between the probe and the carrier forms a shaft extending at an angle to the movement path of the carrier. Movement of the carrier can be backwards and forwards, vertical, or horizontal, and the probe has an arm which, at a distance from the rotary axis of the probe, has a part which activates the indicator. Between the probe and the carrier is a damper which evens out the effect of local viscosity variations or other imbalances in the probe position. (Provisional Basic advised week 84/22)

Abstract: According to the system for monitoring a water area with regards to presence and localization of unknown objects, which transmit sound, in particular submarines three or more listening devices (A1, A2, A3) are thrown out in an area, where indication about an unknown object has been obtained. The listening devices are provided with hydrophones and radio transmitters for transmission of received sound by modulation on a carrier. The devices cooperate with stationary radio stations (M1, M2, M3), where the sound waves are demodulated. Time correlation between the sound waves from an object received by three selected listening devices gives information about the position of the object relative to these selected listening devices. If the position of the listening devices is unknown, for example if the devices are floating free, this position can be determined by comparing the mutual time position for a particular radio signal transmitted from each listening device when received in three stationary radio stations with known positions. The listening devices may suitably also be provided with receivers for receiving radio control signals, for example relating to order for activation, selection of radio channel, etc.

Abstract: A scroll type fluid displacement apparatus includes a pair of scrolls each having a circular end plate from which a spiral element extends. Both spiral elements interfit at an angular and radial offset to make a plurality of line contacts to define at least one pair of sealed off fluid pockets. One scroll, the orbiting scroll, is operatively connected to a driving mechanism and a rotation preventing mechanism, such as a ball coupling device, to effect orbital motion thereof. As the orbiting scroll orbits, the sealed off fluid pockets move along the shifting line contacts of the spiral elements to change the volume of the fluid pockets. According to the present invention, the number of turns of the orbiting and fixed spiral elements are different so that these spiral elements are of different length. As a result, the gas pressure distribution within the fluid pockets is asymmetrical which results in a larger moment of rotation for the orbiting scroll. This larger moment of rotation acts on the balls of the ball coupling device to prevent vibration and reduce noise.

Abstract: A stopping arrangement for long drawing elements such as ropes exhibiting essentially two parallel, opposing clamping surfaces. The clamping surfaces are so arranged as to pull against one another, so that a pressure is exerted on the drawing element when it is moved in a particular direction, and as to move apart, causing the pressure to reduce, when the drawing element is moved in the opposite direction. The aforementioned clamping surfaces extend essentially in a straight line in their principal sense and are so arranged as to move towards and away from one another in a parallel movement. In this way the drawing element will have imparted to it essentially rectilinear clamping over a certain distance at a uniform clamping force, with one of its clamping surfaces being arranged on an element which is so arranged as to move along an oblique path in relation to the second clamping surface, which is situated on a support component connected to the last-mentioned second clamping surface.

Abstract: The process for making the spun fleece proceeds in a filament-spinning unit having a spinning nozzle system, a cooling shaft, a stretching aperture, a diffuser shaft, a continuously moving fleece recovery conveyor and a device for feeding process air and for drawing outflowing air through the fleece recovery conveyor. The cooling shaft has a shaft wall provided with a plurality of air orifices. That allows process air required for cooling to be fed into the cooling shaft. That air flow at least partially is drawn through the fleece recovery conveyor. The thickness of the spun fleece is measured on the fleece recovery conveyor in the transport direction downstream of the diffuser shaft. The measured value is compared with a predetermined set value. On deviation of the measured value from the set value the setting angle of the air control flap or flaps which are located adjacent the entrance of the stretching aperture is changed. On a positive deviation of the measured value of the thickness from the set value the setting angle is increased, on a negative deviation the set value is reduced.

Abstract: A floating dock comprising bottom caisson 10 and side banks 11, 12 and fitted with a keel block 14 has conventional ballast tanks 15 in the bottom caisson. If the dock is to be placed in an area with limited water depth, the caisson will have low elevation, which can mean, with the required height over the keel block, that the ballast tanks' capacity will not be enough to lift the caisson's deck up over the water-line. An increase in the lifting force can be obtained by arranging a number of pneumatic cushions under the caisson bottom, each one enclosed in a "skirt" of flexible material which, with the sinking of the dock, can be crumpled up against the harbour bottom without encroaching to any great extent on the available water depth. <IMAGE>
