Abstract: A transport mechanism for piece goods, such as bottles, can cardboards, trays or the like, which consists of at last two transporter sections that each have at least one drive unit of its own, which is adjustable in rotary speed, with a coordinated control module, with the control module connected with a central control-regulating unit for the transmission of signals. The control-regulating unit has at least one transmitter, and the control module has at least one receiver for wireless signal transmission, particularly by radio.

Abstract: The invention relates to a method for the control of the chain drive mechanisms of underground working machines and a correspondingly equipped chain scraper conveyor. The invention proposes to filter out a detection signal (Serk), representative of the currently arising vibrations of the chain (1), from the operating data of the main and auxiliary drives (I, II) by means of a detection device (34), and to take this to an active suppressor (35), which generates a time-variable control signal (STilgung) in accordance with a suppressor function, with which, in the frequency range of the vibration of the chain, a change is effected to a control value, e.g. (Ssoll) for the closing pressure adjustment of a multiple disc clutch (6) of at least one drive unit for the suppression of vibration by the abstraction of energy from, or the introduction of energy into the chain (1).

Abstract: The invention relates to a transport mechanism for piece goods, such as bottles, cans, cardboards, trays or the like, which consists of at least two transporter sections that each have at least one drive unit of its own, which is adjustable in rotary speed, with a coordinated control module, whereby the at least one control module is connected with a central control/regulating unit for the transmission of signals. This control-/regulating unit has at least one transmitter, and the control module has at least one receiver for wireless signal transmission, particularly by radio.

Abstract: The invention relates to a method for the control of the chain drive mechanisms of underground working machines and a correspondingly equipped chain scraper conveyor. In chain scraper conveyors with a large distance between the main and auxiliary drive stations, e.g. a distance of more than 400 m, a chain breakage in the bottom run or a shaft breakage can arise, which can be traced back to vibration phenomena in the chain. The invention proposes to filter out a detection signal (Serk), representative of the currently arising vibrations of the chain (1), from the operating data of the main and auxiliary drives (I, II) by means of a detection device (34), and to take this to an active suppressor (35), which generates a time-variable control signal (STilgung) in accordance with a suppressor function, with which, in the frequency range of the vibration of the chain, a change is effected to a control value, e.

Abstract: A method and a device for the control of the treatment of the interior of bottles or similar containers, where the introduction of the fluid into the interior occurs by means of a nozzle presenting an exit opening, and a control is performed to determine the presence of a fluid jet in the area after the exit opening and/or the fluid inlet leading to the exit opening.

Abstract: A method for correcting the gaze direction of persons in a digital image where an angular error between the gaze direction and the camera axis is determined. The pupils of both eyes in the image are then segmented and displaced within the image plane. Areas which have become free are filled in using the color of the eyeball. Any interfering edges produced are attenuated in a subsequent processing step (e.g., by using a low-pass filter). The method is also applicable for a sequence of images over time.

Abstract: A piston with at least one compression ring, a top end and a longitudinally extending axis for an internal combustion engine. The piston includes at least one compression ring groove defined by first and second spaced lateral surfaces for receiving the at least one compression ring. The first lateral surface is located nearest the top end of the piston. At least one of the first and second surfaces includes a plurality of profiles extending circularly around the axis and having a depth in the range of 0.003 mm to 0.015 mm and a width in the range of 0.02 mm to 0.2 mm.

Abstract: A coated piston and a process for applying same to a piston of an internal combustion engine having a cylinder. The piston and cylinder are made primarily from a lightweight metal. Graphite bonded in cured resin is applied to the piston and forms a durable running layer.

Abstract: A container for storing a magnetic tape cassette or the like includes a housing and a slide. The slide is displaced in the housing from the inserted position to the extended position and vice versa by an automatically coilable spring strip which has a coil portion engaging the slide and an end fastened in the housing. The spring strip, upon winding up, exerts on the rear wall of the slide a spring force.
