The present invention is based on the realization that the carbon dioxide component of industrial gas streams also containing steam can be processed so to utilize either as latent and / or sensible heat the heat available from the steam component to assist in separating carbon dioxide from the remainder of the gas stream. For example, flue gases produced by power stations burning brown coal, black coal or natural gas inherently contain a useful amount of energy that can be harnessed according to the present invention. According to particular preferred forms of the invention, nitrogen and sulphur constituent such as SOx and NOx, H2S and other nitrogen containing compounds may also be removed from the gas stream through direct contact with the absorbing medium and used to produce by-products such as fertiliser material.

The present invention provides a fluorescence-based modeling method that is capable of capturing the dynamic changes of different membrane foulant fractions that occur in fluid filtration operations. Principal component analysis is utilized to de-convolute spectral information captured within fluorescence EEMs into principal component scores that are related to different known foulant groups. The principal component scores are then used as states within a system of differential equations representing approximate mass balances of the main foulant groups to obtain a dynamic forecasting of membrane fouling. Based on the fouling dynamics forecasted by this modeling method, an optimization strategy can be developed for estimating the optimal membrane back-washing scenario for minimizing energy consumption while maximizing clean fluid production.

Systems and methods of autonomously driving a vehicle to one or more locations, or repositioning the vehicle, to achieve optimal solar exposure are provided. Operating conditions of the vehicle, environmental conditions, as well as road conditions may be considered when determining whether or not to move, relocate, or reposition the vehicle to achieve optimal solar exposure. The optimal solar exposure is that which allows a power storage device of the vehicle to be charged to a desired state of charge. Additional considerations, such as the time needed to travel to a new location(s) and return from the location(s) in time for a next use of the vehicle, may be taken into account. Any energy expenditures that may result from traveling to / from the new location(s) may also be considered.

Apparatus and methods for selectively separating a volatile constituent of a particle from a gas stream for analysis. Particles are separated from bulk flow by inertia and impacted in a cavity containing a small but stable vortex or eddy. Heat is applied to volatilize constituents of the particles. The gas entrained within the vortex, which exchanges only slowly with the bulk flow, is withdrawn for analysis. In this way, a high volume flow containing particles of interest is reduced to a low volume flow containing a vapor concentrate. Advantageously, the apparatus may be operated at very low pressure drops in fully continuous, semi-continuous or batch mode according to the requirements of the downstream analytical unit. The apparatus finds use in active surveillance, such as in use of aerosols to detect explosives or chemical residues on persons, vehicles or luggage in real time.

Operations in an electrolytic cell for producing aluminum are controlled by sensing infrared radiation on an outer surface of a cell chamber to determine an actual temperature. When the actual temperature is greater than a target temperature, a crust hole is repaired or the actual rate of addition of aluminum fluoride to the cell is increased. When the actual temperature is less than a target temperature, the actual rate of addition of aluminum fluoride to the cell is reduced.

The drawing press according to the invention includes a support structure for supporting a metal sheet holder which is part of a tool and supported on the press frame via the support structure. The metal sheet holder is assigned a plunger with a die tool, whereas the plunger is moved by means of a plunger drive which includes a blocking position. The blocking position is obtained, for example, by a drive which, in the locking position does not transmit any movement of the drive output to the driving servomotor. This can be achieved, for example, by an eccentric drive in the stretched position thereof. For performing the actual drawing stroke, the stamping tool is vertically movably supported. A carriage is raised or lowered by the press table by means of a table drive. As table drive, preferably a servomotor with a non-linear drive, such as an eccentric drive is used.

A charging device for an electric vehicle, which charging device can be protected against unauthorized access in a particularly reliable manner. The charging device for an electric vehicle has a bolt for locking a connection between the charging device and a further charging device. If the charging device is mechanically connected to a further charging device for charging purposes, this mechanical connection is then locked by a corresponding end of the bolt being moved into a retaining opening in the further charging device. A retaining opening of this kind can, for example, be damaged by a broken web which serves for locking such that locking is no longer possible. Therefore, a device is provided which can prevent movement of the bolt in the direction of a locking position when the retaining opening is damaged in this way. A locking arrangement which is damaged in the above manner therefore fundamentally does not remain unnoticed. Charging therefore preferably requires sufficiently undamaged, correct locking of the two charging devices involved.
