Abstract: A system for parking validation includes at least one sensor, at least one processor, and a memory device. The at least one sensor and the memory device are operably connected to the at least one processor. The memory device may include an image capture module, a text recognition module, and a parking determination module. The modules cause the at least one processor to obtain at least one image of from the at least one sensor, recognize text located within the at least one image, determine parking-related information from the text, determine at least one parking spot associated with the parking-related information, determine when the at least one parking spot associated with the parking-related information is at least one of available for parking, not available for parking, and available for parking with a voucher.

Abstract: A filter including a filter housing with a horizontal partition wall dividing the filter housing into a dean-gas chamber and a dust chamber. The filter has an inlet part in open communication with the dust chamber. The inlet part is configured for supplying a dust-containing flow of gas to the dust chamber. The gas flow is conveyed through the filter elements and upwards into the dean-gas chamber where the filtered gas is discharged through a clean-gas outlet. In the filter housing, a cylindrical inner portion is arranged that encircles the filter elements. A round-going inlet part is opposed to the cylindrical inner part. The round-going inlet part has a larger diameter than at least a portion of the filter housing that adjoins the inlet part. Gas flow is divided into an upwardly and downwardly oriented gas flow controlled by arrangement of the cylindrical inner part.

Abstract: The invention relates to a filter comprising a filter housing, an inlet and a cylindrical inner portion. The inlet is configured for conveying a gas flow into the filter whereby the gas flow is conveyed around a gap between filter housing and inner part, said inlet configured for supplying a particle-containing gas flow to the filter through the filter elements and out through a clean-gas outlet.

Abstract: The invention relates to a filter (1) comprising a filter housing (2), an inlet (13) and a cylindrical inner portion (14). The inlet (13) is configured for conveying a gas flow into the filter whereby the gas flow is conveyed around a gap between filter housing (2) and inner part (14), said inlet (13) being configured for supplying a particle-containing gas flow to the filter (1) through the filter elements (7) and out though a clean-gas outlet (9). In the filter housing (2) a cylindrical inner part (14) is arranged that encircles the filter elements (7) at least across a portion of the length of the filter elements (7) and that, on the filter housing (2) opposed to the area where the cylindrical inner portion (14) is arranged, a round-going inlet part (8) is configured, which inlet part (8) has a larger diameter than at least a part of the filter housing (2) that adjoins the inlet part (8).

Abstract: In an apparatus for making dry ice pellets having plural pressing chambers, each pressing chamber is provided with a movable piston for compressing carbon dioxide into solid state and for pressing the solid carbon dioxide through a perforated plate disposed at the end of the pressing chamber. Through connecting rods, the pistons in the pressing chambers are connected with a common crankshaft driven by a motor. The pressing chambers are provided with an inlet for supplying the carbon dioxide in fluid state and with outlet for carbon dioxide in gaseous state. In this way a very compact construction is achieved which is suited for mobile units, particularly dry ice blasting units.
