Abstract: A conveyor for moving products P to be cut by a jet of high-pressure liquid exiting a nozzle of a cutting machine in a vertical direction, including a plurality of continuous loops arranged parallel to one another and stretched between two drive rollers so that each determines an upper run and a lower run, each loop including at least two longitudinal walls; and two guide members associated with at least each of the loops and arranged between the two drive rollers, and enabling the upper run of the at least one associated loop to be twisted so that its longitudinal walls are, between the two guide members, parallel to the direction D.

Abstract: A device incorporated into a waterjet cutting machine provided with at least one receiving tank and a movable nozzle, the device being capable of sensing a high-pressure waterjet coming out of the nozzle and including a movable receptacle arranged inside the receiving tank in line with the nozzle, the lower portion of the receptacle being connected to a flexible pipe connected to the bottom of the receiving tank, and—a drive for supporting and moving at least part of the receptacle including the pipe assembly, the drive including a driving member rigidly connected to the nozzle, and a driven member attached to the receptacle, the driving member and the driven member not being mechanically connected.

Abstract: A device (I) for moving a treatment head (JO) and a tray (20) in relation to a plane P., The tray (20) of any shape is inscribed within a rectangle of width A and length 0.8., and includes a first driver (21) suitable for cooperating with a first actuator (22) so as to move the tray (20) in translation within a plane that is parallel to said plane .P. in a movement zone (30) formed from at least two perpendicular edges associated with a reference frame, Q, y, in a direction that is normally parallel to one of said axes or y, the device. (I) The device includes at least: a mobile arm (11) of length R pivotably mounted on one of its ends about an axis £ that is perpendicular to said plane .P., set in motion by a second actuator.

Abstract: A device for moving a plate oriented in a plane P in a direction parallel to that plane P, said plate including at least two opposite edges parallel to one another, said plate including at least two arms parallel to one another and movable in a plane parallel to said plane P, one of said arms being directly moved by a first actuator, the other arm being driven by said first arm via a connection member, a drive member mounted on the free end of each of said two arms such as to be pivotable about an axis perpendicular to said plane P and moved by a second actuator, each drive member engaging with an actuation member arranged along one of the edges of the plate.

Abstract: Exemplary Embodiments of the invention relate to a device for moving a plate in a plane P parallel to same, said plate including at least two opposite edges parallel to one another, wherein it includes at least two arms parallel to one another and movable in a plane parallel to said plane P, one of said arms being directly moved by a first actuator, the other arm being driven by said first arm via a connection member, a drive member mounted on the free end of each of said two arms such as to be pivotable about an axis perpendicular to said plane P and moved by a second actuator, each drive member engaging with an actuation member arranged along one of the edges of the plate.

Abstract: In addition to the contactor and reactor arrangement (10, 83), a hydrothermal treatment system (60) includes an effluent stream splitting arrangement (86) for receiving hydrothermal reaction effluent and splitting this effluent to produce two separate effluent streams. These separated effluent streams are used to heat at least a water stream and first reactant material stream before these streams are injected into the contactor and reactor arrangement (10, 83). A first split effluent heat exchange arrangement (81) places one split effluent stream in a heat exchange relationship with the water input to the contactor and reactor arrangement (10, 83). A second split effluent heat exchange arrangement (79, 80) places the other split effluent stream in a heat exchange relationship with both the first reactant material and the water input to the contactor and reactor arrangement (10, 83).

Abstract: Heated and pressurized reactant material is caused to come into contact with oxidant in an initial contact zone (Z) within a contactor. vessel (11). This initial contact zone is removed from the walls of the vessel and the structure through which the reactant material is introduced into the vessel. Once in the contactor vessel (11), the temperature of the reactant material is elevated to critical temperature or near critical temperature in at least portions of the initial contact zone. Sulfates and similar ions liberated in the oxidation reaction form salts and precipitate from solution generally in. the initial contact. zone removed from the contactor vessel walls and then tend not to adhere to equipment at points downstream from the initial contact zone.

Abstract: A hydrothermal process (10) is integrated into a wastewater treatment facility (12) to fully oxidize an undigested wastewater sludge produced by the treatment facility. A thickened and conditioned feed mixture comprising sludge from the treatment facility is first pressurized to a critical pressure and then heated to a reaction initiating temperature below the critical temperature. An oxidant is injected into the feed mixture at the reaction initiating temperature to initiate an oxidation reaction in low light-off temperature constituents of the feed mixture to produce a partially reacted mixture and raise the temperature of the partially reacted mixture to at least the critical temperature for water in a supercritical water oxidation reactor (52). Heat from the supercritical water oxidation reaction is used to heat the feed mixture and also, to condition the sludge from the wastewater treatment plant preferably by thickening and heating the sludge.
