A faucet with a rotatable outlet structure includes a main body, a spool disposed in the main body, a connecting structure rotatably received in the main body, an outlet structure rotatably mounted onto the main body and a control lever connected to the spool, wherein the outlet structure includes an outer tube and an inner tube received in the outer tube. The outer tube is engaged to the connecting structure and the inner tube is securely sleeved on the connecting structure. Consequently, the inner tube is rotated with the outer tube when the outer tube is rotated relative to the main body such that inner tube does not be twisted when the outer tube is rotated relative to the main body.

The present invention is directed to a mobile platform for the delivery of bulk explosives to a blast hole. One embodiment of the platform provides the ability to obtain weight information relating to the contents of a tank that is associated with the platform and that, in operation, contains either the bulk explosive or a constituent of the explosive. The platform comprises a vehicle with a frame, a tank, a load cell structure for connecting the frame and the tank and providing weight data relating to the contents of the tank, and a suspension system that prevents relative movement of the frame and the tank that could compromise the load cell structure. Another embodiment of the platform provides a tank for holding an explosive composition and a rotary shaft that supports a mixing blade that mixes the explosive composition within the tank. The platform further comprises bearing structure for supporting the rotary shaft that is located to deter any of the explosive composition from entering the bearing. A further embodiment of the platform comprises a conduit structure for discharging a bulk explosive into a blast hole that includes a substantially rigid tube with an outlet port for discharging a bulk explosive into the blast hole. The tube is adapted to rotate about a vertical axis such that the outlet port can be moved towards and away from the vehicle along an arc of less than 180. In one embodiment, the outlet port can be positioned substantially adjacent to an operator's station to allow an operator to readily view the loading of the explosive into the blast hole.

A fluid transfer apparatus for transferring fluids such as hydrocarbon fuel is disclosed. The fluid transfer apparatus comprises a support member and at least one catenary hose, wherein a proximal end of each catenary hose is suspended from the support member. A distal end of each catenary hose is coupled to a transfer manifold. A tensioning member is arranged for applying a tensile force to the transfer manifold during a transfer operation.

A loading arm includes a stand pipe, a coupler configured to be connected to a tank to deliver a product, and a pipe assembly having a first pipe end pivotally coupled to the stand pipe and a second pipe end pivotally connected to the coupler. The pipe assembly includes a pivot joint disposed between the first pipe end and the second pipe end such that the pipe assembly is movable between a retracted position and an extended position. A linkage assembly has a first portion connected to the pivot joint and a second portion connected to the stand pipe. The linkage assembly is operable to allow for the positioning of the coupler at any of a plurality of points corresponding to the pipe assembly being positioned between the retracted position and the extended position. The linkage assembly is fully supported by the stand pipe such that movement of the pipe assembly does not require manipulating the weight of the linkage assembly.

An object is to provide an emergency detachment device of a fluid handling device, the emergency detachment device having exceptional heat insulation performance and making it possible to handle extremely-low-temperature fluids such as liquid hydrogen. A first coupler 2 and a second coupler 3 are provided with a vacuum section 10 between an inner pipe section 5 and an outer pipe section 6, and are provided with two valves 1 in series. A remaining-fluid-transferring mechanism is provided such that, after second valves 1B provided further inward enter a closed-valve state during emergency detachment, residual fluid that remains closer to the first valves 1A than the second valves 1B is transferred into the inner pipes sections 5 provided further inward of the second valves 1B. Once emergency detachment is in a completed state, heat insulation sections 9 are formed in the space between the first valve 1A and the second valve 1B in each of the first coupler 2 and the second coupler 3, and heat insulation performance is improved by the heat insulation sections 9 and the vacuum sections 10.

According to some aspects, a tug and barge arrangement is provided that is configured with an articulated conduit system for transferring fluid between the tug and the barge. In some embodiments, an articulated conduit system is provided that comprises a plurality of conduits fluidically interconnected by rotatable joints configured to permit positional alterations of the fluid conduits that result from differential movement between a tug and barge.

The invention related to a concrete-pump boom-arm segment having an upper chord (33), a lower chord (34) and two lateral parts (35, 36) which connect the upper chord (33) and the lower chord (34). The boom-arm segment comprises a longitudinal connection (44) between two subregions (41, 42) of the boom-arm segment which adjoin one another in the longitudinal direction, wherein the longitudinal connection (44) extends over a chord portion (56, 66) and over a lateral part portion (53, 63). The lateral part portion (53, 63) is bent over with respect to the chord portion (56, 66) in the first subregion (41) and in the second subregion (42). The material thickness of the chord portion (56) is greater in the first subregion (41) than the material thickness of the chord portion (66) in the second subregion (42). The invention additionally relates to a method for producing such a boom-arm segment. Such a boom-arm segment is well suited for absorbing static and dynamic loads and can be produced in a cost-effective manner.

This disclosure relates to a distribution boom for stationary or mobile viscous material pumps, comprising at least one boom arm having a box profile. The boom arm has two side walls which are arranged at a distance from one another and which are connected to one another by means of two transverse walls which are arranged at a distance from one another. Each side wall has a lead-through opening for a conveying line. Provision is made according to this disclosure for there to extend between the side walls a tube which is fixedly connected thereto and which opens by way of the tube ends thereof into the lead-through openings. Between the tube ends and the adjacent side wall there is arranged a respective flange which projects in an encircling manner over an outer border of the respective tube end and is welded both to the tube end and to the side wall in question.

The invention relates to a system for transfer of a fluid product and its use, comprising at least one tubular arrangement for conveying the product between two locations and having two segments (2a, 2b) articulated to each other by a first of their ends, the opposite end of a first of the two segments being rotatably suspended from a support arm (1) adapted to be installed at one of the two locations and the opposite end of the second segment being able to be connected to a coupling means adapted to be installed at the second location, first means (13, 15) for turning the first segment (2a) relative to the arm, for the purpose of lowering its first end from a storage position on the same side as the support arm and second means (33,11) for pulling up the end of the second segment (2b) which end is adapted to be linked to the coupling means for the purpose of connecting that end to the coupling means (6) from underneath.
