A water cooling tower having an improved water collection system. The cooling tower has an outer shell, legs, and one or more layers of fill material, through which the water to be cooled moves vertically downward. The water is distributed across the upper surface of the fill material by piping and nozzles. A fan underlying the fill material moves air vertically upward through the fill material. T...

An arrangement (100) for washing cellulose pulp, comprising a pulp transport rotor (10) and a number of pulp chambers (12), is provided. Each pulp chamber is partly defined by a perforated surface (12a) of the rotor. The rotor is arranged to rotate stepwise so as to transfer the perforated surface of the respective pulp chambers between different pulp handling zones (Z1, Z2, Z3, Z4). The washing a...

Example embodiments are directed to methods of producing desired isotopes in commercial nuclear reactors and associated apparatuses using instrumentation tubes conventionally found in nuclear reactor vessels to expose irradiation targets to neutron flux found in the operating nuclear reactor. Example embodiments include irradiation targets for producing radioisotopes in nuclear reactors and instru...

Provided is an isotope delivery system and a method for irradiating a target and delivering the target to an extraction point. The isotope delivery system may include a cable including at least one target for irradiation, a drive system configured for moving the cable, and a first guide configured to guide the cable for insertion and extraction from a nuclear reactor. The method for irradiating a ...

The axle has bearings (7) mounted at level of front ends of longitudinal oscillating arms (2). The longitudinal arms are pivotingly mounted at a body of a vehicle via the bearings. Transversal oscillating arms (3) are mounted at the level of rear ends of the longitudinal arms. Each transversal arm is formed by transversal spacers (4, 5) pivotingly connected to each other such that an end of one of...

A workpiece has two cylindrical workpiece surfaces centered on respective parallel axes and each flanked by a pair of arcuately rounded and annular corners also centered on the respective axes. Some of the corners have a small radius of curvature and others of the corners have a large radius of curvature. The workpiece is held and rotated about a main axis parallel to the axis of one of the workpi...

A method is described for processing a signal modulated by frequency division multiplexing in a receiver, wherein the received signal is frequency- equalized. According to this method, the received signal is broken up into a plurality of sub-blocks (r( s )) comprising different portions of the signal, and a frequency pre-equalization step (P(s)) is carried out on at least one of said sub- blocks, ...

Mold (1) for the hot forming of leather consisting of a hard and rigid material body, in form of flat sheet (2) or cylindrical tubular jacket (4), which is provided with a front face (2a, 4a) intended to come into contact with the piece of leather to be formed, and wherein said front face (2a, 4a) is provided with a surface impression (3) whose shape traces out the inverse shape of the embossed in...

A die (1) for making tile production molds (2), comprising a flat plate (1) made of hard, rigid material which copies the shape of the front or rear face of the tile to be produced, and has a number of surface reliefs and/or veins and/or decorative relief pattern on the front face (1a) thereof; the flat plate (1) made of hard, rigid material consisting of a thermosetting resin-based slab (7) of gi...

The present invention relates to a method of obtaining a block tool (4), particularly for working stone materials, a block tool (4) for working both natural and artificial stone materials, and a support or base element (7) for a block tool (4).

The invention concerns an apparatus for generating power, in particular electric energy, from wave motion in water basins. It comprises at least an operating unit, including gearing provided for unidirectional rotation and to continuously operate at least one power generator in response to the movements of a control element susceptible to alternating linear movements deriving from the wave motion....

The present invention provides a process for the conversion of triglycerides in biodiesel by using chlorotrimethylsilane (TMSCI) as efficient catalyst, working in homogeneous phase, and not contaminating the final products. The process allows the complete conversion of triglycerides to the corresponding alkyl esters. The biodiesel and glycerol obtained are cleanly separated in two distinct phases ...
