A device is described for mechanically cleaning fluids, especially for [cleaning] the cooling water that enters a heat exchanger, having a pipe segment (12) as housing, a sieve element (20) that essentially covers the cross section of the pipe, and a suction device (20) on influx side (22) that is capable of moving around an axle (18), the purpose of the device being to aspirate the surface area of sieve element (16) and in this manner clean it, wherein, according to the invention, sieve element (16) forms a partially cylindrical casing having a cylindrical axle (56) perpendicular to axle (24) of pipe segment (12), wherein the open part of cylindrical casing (16) is arranged toward influx side (22) (FIGS. 1, 2).

The invention pertains to a device to separate solid materials from a stream of liquid, particularly from cooling water. In the case of the known devices, difficulties occur in cleaning the filter from fibrous contaminants generally or starting with a certain size. The subject device draws off fibrous as well as coarse grained contaminants equally well.A preferably funnel shaped filter 3 with a suction device 4 running at an angle to the surface line 6 of the funnel filter 3 is arranged in a pipe shaped housing. The inclination creates a force component 19 which transports the coarse grained contaminants to the tip of the filter where they are drawn off by the suction opening 8 of the suction rotor 7. The fibrous contaminants are drawn off by the suction device 4.

The invention relates to a device for cleaning the pipes of heat-exchangers by means of cleaning bodies, generally sponge balls. The removal and reintroduction of the cleaning bodies occurs with the aid of a device installed in the outlet pipe, which consists of a casing (1) with one or two screens (2) arranged within it. The screens (2) end on the downstream side at a pipe (3) with an opening (4). Inside this pipe (3) there is another pipe (5) with an opening (6) which preferably rotates continuously. The cleaning bodies (9) are collected in the inner pipe (5). A pressure water pipe (7) and a cleaning body outlet pipe (8) are connected to the outer pipe (3). When the inner pipe (5) is in the appropriate position, the cleaning bodies (9) are washed out of the inner pipe (5) by pressure water and introduced into the inlet pipe of the heat-exchanger via the cleaning body outlet pipe (8). A lock (11) is built into the cleaning body return pipe in order to introduce and remove the cleaning bodies (9).

The invention provides for an automatically releasing mounting system by dint of which a weight member may be releasably connected to a fishing-line. The mounting system comprises a receptacle resiliently biassed into essentially conical shape. Wall portions of the receptacle are interconnected by a pivotal joint near the upper end thereof, while latch apparatus are provided to releasably connect the lower ends of the wall portions. The latch apparatus include a latch member having a wing formed integral thereto. When the receptacle hits the surface of the water, the relative movement between the water and the wing portion of the latch member will cause moving of the latch member out of the associated latch-catch. Thus the wall portions of the receptacle cooperating in defining the lower aperture of the container can expand. The receptacle including the latch apparatus can be molded as a single essentially flat part. In order to keep this molded part having been correspondingly bended in the conical or cylindrical configuration the pivotal joint is formed by two members associated to one of the wall portions, respectively, and being adapted for releasable mutual engagement.

A process is described for fibre- and surface-level dyeing of wool and blends thereof with other fibers using a compound of formula (1) ##STR1## in which n is 0 or 1, and if n is 1, A is a radical of the formula ##STR2## and B is an alkylene or alkenylene group or a direct bond, or if n is zero, A is a compound of the formula ##STR3## Fibre- and surface-level dyeings, in particular in light to medium color shades are obtained by the dyeing process according to the invention. The dyeing aid according to this invention can be used to substitute formaldehyde containing wool dyeing aids.

Systems and methods for calculating L* in the magnetosphere with essentially the same accuracy as with a physics based model at many times the speed by developing a surrogate trained to be a surrogate for the physics-based model. The trained model can then beneficially process input data falling within the training range of the surrogate model. The surrogate model can be a feedforward neural network and the physics-based model can be the TSK03 model. Operatively, the surrogate model can use parameters on which the physics-based model was based, and/or spatial data for the location where L* is to be calculated. Surrogate models should be provided for each of a plurality of pitch angles. Accordingly, a surrogate model having a closed drift shell can be used from the plurality of models. The feedforward neural network can have a plurality of input-layer units, there being at least one input-layer unit for each physics-based model parameter, a plurality of hidden layer units and at least one output unit for the value of L*.

A dispensing device including a container for a supply of items forming a web. The dispensing device includes a recess formed in an outer wall of the container, a braking unit overlapping the recess. The braking unit includes two lips which work together when items are dispensed and a linear slit between the two lips which enables the items to pass between the two lips, the two lips being fitted with bristles which constitute active elements of the two lips, unattached ends of the bristles of one of the lips extend into, and mesh with, an area of unattached ends of the bristles of the opposite lip. The items are camisole-shaped and sequentially joined bags having a body with a bottom part and handles at the upper part. The bottom part of the body of one of the bags is connected to the leading edge of the handles of the next bag. A nozzle for dispensing the bags is connected to the recess, the nozzle including a hollow cover in the base of which there is an oblong and virtually linear opening, the distance between the edges of the opening being considerably larger than the thickness of a bag. The braking unit is attached to the hollow cover in such a way that it overlaps the linear opening in the hollow cover.
