Abstract:
The invention relates to a process for preparing a catalyst for the desulfurization of hydrocarbon streams, which comprises the steps: (a) preparation of an aqueous suspension comprising: a thermally decomposable copper source, a thermally decomposable molybdenum source, and a solid zinc source; (b) heating of the suspension to a temperature at which the thermally decomposable copper source and the thermally decomposable molybdenum source decompose so that a suspension of a precipitate comprising zinc compounds, copper compounds and molybdenum compounds is obtained; (c) cooling of the suspension obtained in step (b); (d) separation of the precipitate from the suspension; (e) drying of the precipitate. The invention further relates to a catalyst which can be obtained by the process of the invention and also to its use for the desulfurization of hydrocarbon streams.
Abstract:
A cleaning machine for floors and carpets includes a vacuum pick-up in front of the machine for suctioning loose material and debris off the floor. A microfiber cleaning assembly is mounted beneath the machine for cleaning the floor following the vacuum pick-up. The microfiber cleaning element may be motor driven. A source of solution delivers a controlled amount of solution or water to moisten the microfiber cloth. A vacuum motor provides suction to the forward vacuum pick-up, routes the suctioned air through a filter, and the filtered air is then delivered to an air diffuser to dry any residual moisture behind the microfiber cleaning assembly. The microfiber cleaning assembly may have two offset pads driven by a reciprocating or oscillating drive, or one or two cylindrical rollers for receiving and securing the microfiber fabric in the form of a sleeve.
Abstract:
A data center includes a modular building structure forming an enclosure having a bottom side. An external support system extends from the modular building structure. A series of heat sinks are each configured to extend from an interior to an exterior of the enclosure and protrude below the bottom side of the modular building structure into a fluid. Electronic components and devices are housed within the enclosure.

Abstract:
A large manipulator, especially a truck-mounted concrete pump, has a boom base that can be arranged on a frame so as to be pivoted about a substantially vertical axis of rotation. The large manipulator has a pendular element, that hangs down as an articulated boom and a control device for controlling the drive units of the axes of articulation and rotation of the articulated boom. The remote control has at least one inclination sensor which is housed in a housing that is detachably fastened on the pendular element. Two inclination sensors are housed in the housing and are bent at an angle of 90° with respect to each other and with respect to an axis that is parallel to the pendular element axis. The housing has a mark indicating the orientation of at least one of the inclination sensors inside the housing.
Abstract:
Dispensing contents from selected chambers includes measuring a selected volume of contents within a container by rotating a dial located on an underside of multiple chambers in a rotatable drum of the container to open a selected number of the multiple chambers where the selected number of the multiple chambers cumulatively forms the selected volume.
Abstract:
A fluid cooling module includes tubing and a turbulence structure. The tubing is configured to contain a flowing fluid. The turbulence structure disposed inside the tubing and configured to increase fluid movement within the tubing as the flowing fluid flows over the turbulence structure to thereby generate turbulence in the flowing fluid.
Abstract:
A piston for a setting device operated by fluid power is suggested. The piston includes a support body having an annular recess with an axis coinciding with the longitudinal axis of the piston, such recess having at least one annular permanent magnet arrangement therein. The permanent magnet arrangement is segmented in its peripheral direction and consists of at least two accurate magnet segments. The annular recess is in the form of an annular groove with a radially outwardly directed groove opening into which the magnet segments are inserted radially from the outside with the formation of an annular configuration.
Abstract:
The invention relates to a method for setting up a mobile machine (1), particularly an automatic concrete pump, a mobile crane or a movable elevating work platform. With such a method, the subsurface (28) of a site is analyzed for the properties and/or load-bearing capacity thereof before the machine (10) is positioned there and/or oriented and supported by means of flarable supporting legs (20, 24) in set-up positions (VR, VL, HR, HL) suitable according to the determined subsurface properties and load-bearing capacity. In order to determine an optimized set-up position for the supporting legs (20, 24), geodata (38) of a geographic environment that includes the site is read via a computer in a data memory (44) using a layer of subsurface data (40) that defines the subsurface properties and load-bearing capacity. In addition, the geographic position of the machine (1) and the orientation thereof at the site are determined and linked in the form of a data set that defines at least the geographic set-up positions (VR, VL, HR, HL) of the flared supporting legs (20, 24) to the imported geodata and subsurface data (38, 40). Then, the machine (1) is navigated with the supporting legs (20, 24) into a set-up position that is suited according to the imported geodata and subsurface data.
