Wave-generating apparatus (1) that is installed in an aquatic environment (3) and which comprises, as its main elements, at least one elongated profile (5) that moves tangentially in relation in relation to a uniformly-deep floor (4) by the action of a drive mechanism (6). As a result, a wave (2) forms on the profile (5) and moves along with the profile (2). The profile (5) is disposed to form an angle (8) other than 90° with the direction of displacement (7), the purpose being to generate a wave (2) with an escape area and which can therefore be surfed. Some parameters of the apparatus (1) may be adjusted for the purpose of changing the degree of difficulty of the wave (2) that is generated.

A roadside lamp with a heat dissipating design is disclosed. The roadside lamp of the present invention comprises a seat portion and a plurality of light emitting units. A panel is fitted to the seat portion and the light emitting units are fitted to the panel. The back portion of the panel is tightly fitted to a heat dissipating fin-like portion. A pair of rails extends outwardly from the fin-like portion. The pair of rails may be used to connect the roadside lamp with a surface in a place such as a tunnel. For example, a track may be provided on the top portion of a tunnel; therefore, a plurality of the roadside lamps may be fitted to the track in a tidy manner. The pair of rails allows each roadside lamp to be fitted to the track and thus, the location of the lamp may be adjusted.

The present invention relates to a process for washing and sterilizing food products, particularly vegetables. The process comprises the following steps: (a) treatment of the food products by ultrasounds, ultraviolet rays and micro filtering; (b) treatment of the food products under ozone atmosphere, ultraviolet rays and micro filtering; (c) treatment of the food products by ultraviolet rays; and (d) dewatering and drying the food products under controlled atmosphere. The present invention further relates to an apparatus for carrying out the above process.

An apparatus (1) for cooling a bar (10) comprising:—an outer casing (3),—a passageway (2) defining a crossing direction (X) for the bar (10),—at least one drum (4) comprising a plurality of cooling lines (6) each having at least one respective through cavity (9) parallel to the crossing direction (X) and a respective cover (15) which can move between an open position and a closed position, the drum (4) being accommodated in the casing (3) and rotational about a rotation axis (Y) to move the cooling lines (6) between an operating position (11), in which the cavity (9) is aligned with the passageway (2), and at least one resting position (12), in which the cavity (9) is separated from the passageway (2), the casing (3) being shaped so as to touch and hold the respective cover (15) in the closed position when the cooling line (6) is in the resting position (12).

A device for aiding the flight management of an aircraft includes a navigation display, a personalized database capable of storing navigation-aid data, each datum comprising a classification type representative of a family or of one or more categories of navigation-aid data, one or more periods of validity of the said datum, information relating to at least one geographic zone of the said datum, one graphic and / or textual representation of the said datum, selection means allowing an operator to choose one (or more) type(s) of classification, called selected type(s), extraction means capable of extracting from the personalized database the navigation-aid datum or data called extracted data of which the type is equal to at least one selected type, of which at least one geographic zone is situated at a distance, from the flight plan or from the aircraft, that is less than a predetermined maximum distance and of which at least one period of validity verifies a predefined display time criterion, the said extraction means transmitting the said extracted datum or data to the said navigation display capable of displaying the representations of the said extracted data.

The present invention discloses a mining- machine- based slowly inclined thin ore vein mechanized continuous mining method, a middle-section tape transport lane is arranged along an ore body, false inclination uphill is tunneled at intervals of a certain distance; a continuous rib pillar and a top pillar or a bottom pillar are arranged between adjacent back- mining units; accurate mining cutting is started from the lower middle section tape transport lane, a mining machine passes, from the back- mining unit edge position, through the top pillar or the bottom pillar for tunneling left and right false inclination uphill to the upper middle section tape transport lane; back- mining is started from the position of the tape transport lane uphill from the right side, the ore body is back mined by the mining machine to left side uphill, the mining machine is in no load, and descends along the left false inclination uphill to the bottom of the back- mining units, the ore body is back mined by the mining machine from left side uphill position to right side uphill, then the mining machine is in no load, and ascends from the right side uphill to the position near the tape transport lane, the mining is performed in the anti-clockwise direction circulation way, a central position reserved ore pillar is left; ores are loaded onto a belt by a carry-scraper for conveying to a ground surface main ore bin. The conveying is easy, work security is high, back- mining efficiency is high, and production capacity is large.

The invention relates to a method for repairing and supporting an air return roadway in a soft rock working face of a coal mine. Firstly, a side loader is used to pull the bottom, and a roadway repair machine is used to carry out roof lifting and side expansion; For the net cable, use steel sheds for inclined miners, trough-type wooden piles and sided wooden piles to strengthen the support; for the U-shaped steel shed support section roadway, re-erect U-shaped steel sheds, trough-type wooden piles and sided wooden piles for reinforcement support. The present invention is mainly to solve the problem that during the mining process of the working face, under the influence of mine pressure and mining disturbance, the soft rock roadway will converge on the roof, floor and two sides, resulting in a significant reduction in the roadway section, affecting ventilation, pedestrians, material transportation, Coal transportation and other problems. Through the implementation of the present invention, it is also possible to effectively reduce the repair frequency of the roadway, reduce the labor intensity of workers, and increase the advancing speed of the working face, which is of great significance for improving the economic benefits of the mine.
