Abstract: A method is provided for operating a coke oven battery including many identical coking chambers, a raw gas receiver, and throttle devices arranged in the receiver for individually controlling the gas pressure in the chambers. Each throttle device includes an immersion bucket acted upon by water. Gas lines terminating in immersion pipes in the immersion buckets connect the chambers with the receiver. Throttle devices are employed that include an overflow that can be vertically adjusted by an actuating drive for controlling the liquid level in the immersion bucket. For a coking chamber to which a pressure control device is allotted, the setting signals for the actuating drive allocated to the time pressure curve in the process of carbonizing coal to coke are recorded as a position-time curve. The actuating drives of throttle devices that are allocated to coking chambers without pressure control devices are controlled according to the position-time curve.

Abstract: A sintered connecting rod for an internal combustion engine comprises a connecting rod eye (1) for receiving a piston pin, a connecting rod big end (3) for holding the crank pin and a shaft (2) made of two diverging longitudinal bridges (4) which are optionally stiffened by a connecting bridge (5) and whose mutually facing bridge flanks (11) are connected in the zone of the connecting rod big end (3) by a central concave rounding (9). In order to ensure advantageous loading conditions it is proposed that the longitudinal bridges (4) of the shaft (2) diverge from the connecting rod big end (3) to the connecting rod eye (1).

Abstract: A device for controlling the gas pressure in a coke oven chamber, has an immersion cup, to which water is supplied, and with an immersion pipe which is connected to the gas space of the coke oven chamber and terminates in the, immersion cup. The immersion cup has an overflow and a closeable outflow. To control the liquid level, an outflow pipe for water is provided, the inflow-side end of which projects into the immersion pipe and contains casing-side inflow orifices for the inflow of water. Within the outflow pipe is arranged a slide which is open on both end faces and which closes the inflow orifices of the outflow pipe in the longitudinal direction according to the position of said slide and forms a vertically adjustable overflow for the water flowing into the outflow pipe.

Abstract: A method of producing batches of micro particles includes affixing a substrate sheet to a support and cutting the substrate sheet with a laser device to define a plurality of micro particles. Before, after or during the cutting of the substrate sheet, the region of the substrate sheet defining each micro particle is marked with a code or other identifying marking using a laser device. The code or other identifying marking is unique to the particular batch of micro particles to uniquely identify that batch. The micro particles are removed from the support by a solvent. Preferably, a single laser device is used for cutting the substrate sheet and marking the micro particles. Alternatively, separate laser devices may be used for cutting the substrate sheet and marking the micro particles.

Abstract: A system and method for authenticating a multi-sided die by viewing the die under invisible ultraviolet light. A die body has a plurality of sides of substantially equal area. A plurality of visible markings for indicating a roll of the die are disposed on the die sides. One or more of the markings include a substance which visibly reacts with invisible ultraviolet light. One or more authentication marks including a substance which visibly reacts with invisible ultraviolet light are arranged in a selected pattern on one or more of the die sides. A position of the authentication mark or marks in the selected pattern corresponds to the visible marking having a substance which visibly reacts with invisible ultraviolet light. An overlay key correlates the position of the authentication mark with the visible marking.

Abstract: An apparatus for sterilizing objects has a sterilization chamber and a microwave source for applying microwave radiation to objects inside the sterilization chamber.

Abstract: The present invention relates to an exhaust gas treatment device (1), in particular for an internal combustion engine, preferably in a motor vehicle, comprising a housing (2) as well as a substrate body (3) which is situated therein and through which exhaust gases can flow in an axial direction (5). The substrate body (3) is supported axially on the housing (2) via an axial bearing (8) on at least one axial end face (11). To improve the axial support of the substrate body (3), the axial bearing (8) has a supporting ring (10) mounted on the housing and having a U-shaped profile (12), which is open axially toward the end face (11). A bearing ring (17) made of bearing material engages into the U-shaped profile (12) of the supporting ring (10) on its axial end, which faces away from the substrate body (3) and is supported thereon axially. With its axial end facing the substrate body (3), the bearing ring (17) is supported on the end face (11).

Abstract: In a connector adapted to be selectively connected to two types of cards inserted towards an insertion direction and different from each other in width thereof, a housing defines a guide space and has a guide portion for guiding an insertion of a selected one of the cards. The guide portion extends in the guide space in a particular direction intersecting the insertion direction. An eject mechanism is provided for moving the selected one towards a removing direction opposite to the first direction. The eject mechanism includes an eject member to be engaged with the selected one and moved together with the selected one, an operating member for moving the eject member towards the removing direction, and a rotary member having a rotation center and rotatable around the rotation center to transmit operation of the operating member to the eject member. The rotation center is disposed in the guide space.

Abstract: A terminal portion of a contact has a first portion extending from a one-side surface of an insulator, a second portion extending so as to be connected to a conductive portion of a board, and a third portion joining between the first and second portions. The second portion is bent using a joining portion between the second and third portions and as a fulcrum. The third portion is bent using, as a fulcrum, a joining portion between the first and third portions and in a direction away from the board toward the joining portion between the second and third portions.

Abstract: A transformer having variable reluctance, that controls the amount of power conveyed from an input to a load, based on a value selected by a computer control. The load power is varied by controlling the section and air gap between two parallel iron cores and a magnetic reluctance shifter positioned between the cores to vary the magnetic reluctance. The shifter is rotated by a motor. The position of the shifter varies the reluctance of the transformer and thus varies the amount of voltage transmitted from the primary winding to the secondary winding of the transformer. The iron core transformer is mounted in a non-magnetic frame and the windings are made from insulated braided copper strips, or insulated twisted cable.

Abstract: A convertible piece of upholstered furniture can be converted via motorized conversion aids from a seat function into a bed, by way of any desired number of intermediate stages, and vice versa. All movable parts can be fully stressed by a person during conversion, even when a person is sitting or lying on the piece of furniture. These changes can take place even when the piece is being used by a person, whereby each movable part of the piece of upholstered furniture can be changed by means of a motor drive having a control. The footrest and the seat part are configured so that they can move out of a base frame with their metal fittings. A lever construction arranged on the metal fitting of the footrest and a motor drive adjusts the height and angle of the footrest and moves the piece of furniture to the various positions.
