Abstract: A dyeing machine comprising at least one dyeing module in which a first squeezing device for a textile support, a first treatment tank, a central tank, a second treatment tank and a second squeezing device are located in sequence is described. The dyeing machine also includes a hydraulic system for feeding, circulating and alternately adjusting the levels of process fluids in the tanks. The tanks are preferably enclosed in a hermetically sealed upper covering shell. The two treatment tanks have the same shape, the same dimension and capacity characteristics, and are symmetrical with respect to a plane of symmetry lying in the central tank and arranged perpendicularly with respect to the direction of advance of the textile support. The dyeing machine is provided with means for moving the textile support, configured to advance the textile support alternately in both directions, i.e.

Abstract: An apparatus and method for conditioning water in open fish breeding cages, which can solve the problems of “bloom of harmful seaweed” and the “lack of dissolved oxygen concentration in the water”. The apparatus includes a tube having adjustable open upper and lower ends and an impeller for drawing a major water flow in either direction through the tube. To solve the “bloom of harmful seaweed” the apparatus draws water upward from deeper water with low algae concentration to the bloom zone, dissolving and moving the harmful seaweed far away from the cages. To solve the “lack of dissolved oxygen concentration” the apparatus draws water downward from the surface water having high concentrations of dissolved oxygen to deeper water with low concentrations of dissolved oxygen, increasing the dissolved oxygen concentration in the middle and the bottom of the cages, where the biggest oxygen consuming fish concentration are located.

Abstract: An aquatic shredder includes a watercraft and a pair of large, high speed propellers mounted at both the bow and stern ends of the watercraft. The propellers are configured to not only propel the watercraft through the water but also to chop vegetation at or near the water surface. Moreover, the bow propellers are similar in construction to the stern propellers so that they similarly effect comminution of the vegetation and propulsion of the watercraft. In particular, each pair of propellers extends completely across the width of the watercraft and projects laterally outward beyond the port and starboard sides of the watercraft. Each pair of propellers is preferably supported by a swingable frame that permits the user to raise and lower the propellers as desired. To enhance the cutting action of the propellers, the blades of the propellers may be provided with fore and aft extending knives.

Abstract: The present invention is directed to an apparatus that extracts the cooler deeper water with the warmer water near the surface in order to reduce the temperature of the upper layers of water within the cage. At the same time, the apparatus produces a water current at the surface that carries the harmful algae away from the set of cages. In addition, the apparatus extracts the oxygen-rich water from the surface and injects it into the deeper water that lacks sufficient oxygen content.

Abstract: The pole includes a shaft at one axial end of which a small basket is replaceably mounted by a removable bayonet-type attachment device which comprises a locking member capable of preventing relative rotation between the shaft and the basket once the latter is fixed to the shaft in the operating position.

Abstract: Luminous signs, specifically those with the ability to change the presented information sequentially, include an electro-mechanical system that produces the synchronized overlapping of two or more preprinted films with translucent properties, in such a way that with an internal luminous source, the sign is capable of creating the effect of real movement, and in the night or in the darkness, the information images displayed by the sign seem to float in the air. The present invention also provides an illuminated sign with the capability of displaying such information or images on more than one of its surfaces.

Abstract: A rotary distributor fuel injection apparatus comprises a distributor rotor (3) having a fuel inlet port (c) and delivery port (d) which communicates in turn with successive ports (g) supplying individual cylinders. The rotor (3) has a central axial passage (b) connected to the ports (c) and (d) and a radially drilled port (e) which aligns succesively with ports (h), radially drilled in the sleeve (13), whose rotation is controlled by a helical groove (i) on a thrust sleeve (14) through a peg (17) located on the sleeve (14). Centrifugal governor weights (15) and (16) control the position of the sleeve (14) and thereby the instant at which the port (e) communicates with a port (h) to terminate injection.

Abstract: An oxidation intensifier apparatus for continuous warp-chain indigo dyeing machines for dyeing a plurality of adjacent spaced parallel warp threads passing in a traveling path through a plurality of dyeing and squeezing units includes a first oxidation intensifier unit (10A) on one side of said traveling path, a second oxidation intensifier unit on the other side of said traveling path between two dyeing and squeezing units (I and II), and a fan (19) in each unit for blowing air onto opposite sides of the warp threads passing between the units. Each oxidation intensifier unit has an inlet on which the fan (19) is mounted, a diffuser (22) having an air inlet (21) adjacent the output side (20) of the fan and a diffuser outlet (23) in adjacent spaced relationship to the traveling warp threads (12). Each diffuser may contain in its interior a deflector (25) and/or a grille-type conveyor (26) to assure uniform distribution of the air delivered from the fan to the traveling warp threads.
