Abstract: The invention relates to an intake arrangement (1) for the combustion air (2) of an internal combustion engine (3) of a handheld portable work apparatus (4), such as a cutoff machine, motor-driven chain saw or the like. An air filter (5) is provided for purifying the combustion air (2). Dust-laden combustion air is directed onto the air filter via openings (6) of a filter housing (7). The combustion air (2) is purified by the air filter (5) and is drawn by suction by the engine (3) via an intake pipe (25) of a carburetor (8). A carrier airflow (10) is provided in a flow channel (15) for continuously or intermittently transporting away dust (11) deposited on the air filter (5). The combustion air (2) and the carrier airflow (10) are spatially separated via a discharge tube (13). In this way, a minimization of the dust load of the air filter (5) is ensured on the one hand and a continuous transport away of the dust (11) from the air filter (5) is ensured on the other hand.

Abstract: Glass containers are taken to a high temperature in an annealing furnace and removed from the annealing furnace belt by grips of a gripping device. The gripping device is then moved by a handling device first vertically upwards, then horizontally above a fluidized bed and then downwards into the fluidized bed in order to coat the glass containers with a powder, it is then taken upwards out of the fluidized bed and finally moved horizontally over a conveyor belt. There, the glass containers are released from the gripping device and set down on the conveyor belt which takes the powder-coated glass containers through a second curing region in which the powder coating is cured to form a substantially duroplastic layer.

Abstract: Sheets are printed by being automatically run twice through a printing machine. The first sides of each of the sheets are printed in one, or a plurality of colors during a first printing pass. The sheets so printed are then placed in an intermediated storage facility, which is located within the printing machine. These sheets are then rotated 180 degrees and are printed on second sides in one or a plurality of colors during a second printing pass. The sheets are then fed to a final storage device.

Abstract: A sheet-fed rotary offset printing machine accomplishes multi-color printing. A central impression cylinder carries sheets to be printed as they pass by at least two serially located blanket cylinders. These blanket cylinders are provided with ink images from cooperating plate cylinders. A sheet is gripped only once by grippers of the impression cylinder and is held in this single gripping operation during printing. At least one short inking unit is associated with each printing cylinder.

Abstract: The position of a printed web passing through an elongated dryer is shifted laterally during passage of the web through the dryer. A component of the resultant of all of the frictional forces acting on the web is caused to point in the lateral direction of the desired web shaft. This resultant of the frictional forces is obtainable by changing the spacing of blower nozzles, or by changing the pressure of discharged drying fluid across the width of the web.
