Abstract: The top layer of water is pumped down to the bottom layer to prevent it from becoming overgrown, or to completely or partly restore it. A floating pump arrangement which is driven by wind or wave energy is used. The quantity of water pumped per unit time is low so that the increase in oxygen content happens over the most important time period and so that the water exchange is slow.

Abstract: An articulated automotive vehicle, such as a fork-lift truck, comprises a forward vehicle section 11 which is pivotally connected to a rearward vehicle section 12 by means of a vertical journal shaft 13. Under normal driving conditions the vehicle runs on carrying wheels 19, 20, 21 and can be turned with the aid of control means 14. In order to reduce the requisite turning radius of the vehicle to a minimum, at least one of the vehicle sections is provided with an auxiliary wheel 22, 23 which extends substantially transversely to its carrying wheels and which can be moved into engagement with the ground 18 or other supporting surface by means of a jack (24, Figure 2), so as to lift the carrying wheels 21 of that section from the ground 18. The raised section of the vehicle can then be turned while moving on the transverse auxiliary wheel, either manually by means of the driver or by automatic control means, by utilizing the standard vehicle control device 14. <IMAGE>

Date Sep. 7, 1990.The present invention relates to a method for resource allocation in a radio system comprising base stations with respective coverage areas and mobile units. The interaction between the stations in the system is defined with the aid of measured and/or calculated field strengths from all base stations on relevant traffic routes in the geographic area of the radio system, preferably in the form of an exclusion matrix. An allocating matrix is formed by compressing the exclusion matrix by means of an allocating algorithm. The algorithm utilizes figures of merit which are on the one hand calculated by mathematical/logical means to form possible combinations of stations and utilizes on the other hand a random technique for selecting one of these combinations. The algorithm is iterated a number of times and different allocations are obtained thanks to the random technique. The best one of the allocations from any point of view is selected.

Abstract: A high flow sodium chlorate oxygen generator assembly (10) of a relatively small diameter. The generator assembly includes a chlorate candle (12) mounted within a containment vessel (14, 16, 18), the chlorate candle being provided with a deep conical recess (54) which is thinly coated with a rapidly combustible material (56). Ignition of the rapidly combustible material is achieved by extending a hollow ceramic tube (58) from a primer (38) located at one end of the containment vessel, the hollow tube directing the flame from the primer, when ignited, towards the center of the deepest part of the conical depression. The above construction provides a high surface area for burning, and also intensifies the heat flux within the chlorate candle thereby substantially increasing the rate of oxygen output over known chlorate candles of comparable diameters.

Abstract: The prefabricated creep foundation in accordance with the invention is a building system for the laying of the foundations for a heated building with a beam structure above an enclosed, unventilated creep space. The foundations are constructed from base plates made of concrete, foundation beams made of concrete with internal cellular plastic, and ventilation grids for ventilation. The foundation beams consist of an externally reinforced high concrete slab with thick, cast-on-cellular plastic insulation on the inside. The creep space can be inspected more easily thanks to the considerable height of the foundation beams. The thick cellular plastic insulation on the foundation beams enables surplus heat to be utilized, so that the laying of the foundations can take place at a reduced foundation depth. The foundations can be laid using a crane, and can be adapted to the requirements of the project. The invention also relates to a method and means for the production of elements from which the foundations can be constructed.

Abstract: A friable silicon nitride body is prepared by infiltrating a non-friable silicon nitride body with a fluid which expands upon freezing, rapidly freezing the fluid, and thawing the frozen fluid. Silicon nitride flakes and chunks obtained with only light pressure on the friable body may then be final milled to a desired particle size more rapidly and with less energy input than with conventionally processed silicon nitride. The silicon nitride body may have a higher density than has previously been used to prepare silicon nitride powders, thereby preventing the generation of potentially hazardous whiskers in the final powder product.

Abstract: The present invention relates to a gripping device for gripping and handling one or more rolls R or bales of paper material or the like, which gripping device has a clamping-force-generating power unit 8 and grippers 2,3 which are actuated by the power unit 8 to grip at least one roll R or bale located between them. In order to eliminate the risk of over-hard clamping of low rolls R or bales whilst still being able to produce sufficient clamping force to handle higher and hence heavier rolls R or bales, at least one sensor 9 is arranged to be moved out of a normal position N and/or to be made to change its normal shape as a result of at least one roll R or bale coming into contact with the sensor 9 when the gripping device is guided to a gripping position relative to the roll R or the bale, the sensor 9 further being arranged to maintain its normal position N and its normal shape when the gripping device is guided into a gripping position relative to a lower roll R or bale which does not reach up to the sensor 9 and the sensor 9 interacting with the power unit 8 in such a way that this provides the grippers 2,3 with greater clamping force if the sensor 9 has been moved out of its normal position N and/or been made to change its normal shape than if the sensor 9 maintains its normal position N and its normal shape when the grippers 2,3 are to grip the roll R or the bale. <IMAGE>

Abstract: A ventilation slot valve that is both operationally safe and discrete in appearance is made of a flat channel sleeve (2), which is inserted in the slot opening so as to cover the edge thereof with a narrow flange (16), an associated oblong valve plate (14) in its closed position being located entirely inside the front opening of the sleeve. Between each of the ends of the oblong valve plate (14) and a rearmost inner area (40) of the channel sleeve is arranged a projector lock (46) of the spring actuated, pressure actuated type, and these opposed locks are connected with the valve plate (14) in a manner such that the latter may at each end be pressure actuated for subsequently being projected a short distance even if the valve plate is not correspondingly released at its opposite end. The valve plate (14) may thus be brought into an open position by a successive pressure actuated release of its two ends, and it can be closed just by being pressed home for snap locking of the projector locks (46). The valve plate may have a discrete appearance without visible actuator means and almost as an integral part of the mounting surface.

Abstract: The splicing system aligns fibre ends with one another and positions the end surfaces adjacent to each other. The fibre parts adjacent to the abutting end surfaces are heated so that they fuse together. The repeated value of at least one optical property, on which the optical losses in the fibre splice are dependent, is determined during heating for the fibre area adjacent to the splice. - Heating is continued until the measured values of the optical properties for the areas adjacent to the splice have a deviation from one another below a predetermined threshold value. The optical value is the optical transmission dia. (MFD) for the fibre areas adjacent to the splice. The intensity of the light radiation from the fibre heated parts is recorded (29) during heating and the optical property is determined from the recorded light intensity.
