A test rig for dynamic test assignments on internal combustion engines is equipped with a preferably electrical drive and/or loading device which is coupled to a control device for adapting and controlling setpoint values for a speed and a torque characteristic. For a test rig of this kind, in order to enable the setpoint values determined by a speed and a torque characteristic to be optimally adapted and controlled for the respective test assignment and so that they can be reproduced on the test rig in the best possible manner, the control device can be adapted in terms of adjusting the weighting of speed control to torque control.

An injector insert pipe is arranged in the gas channel of a nozzle for injecting oxygen-containing gas into a pig iron production unit, wherein an interspace which surrounds the pipe is present over the entire pipe length between the wall of the gas channel and the pipe outer wall. The pipe extends at least as far as the nozzle end face which contains the mouth of the gas channel. The pipe space is connected to an oxygen-containing gas feed line, and the interspace is connected to a protective gas supply line. In a process, oxygen-containing gas is fed into the pipe space, which after it has flowed through the pipe, enters the production unit at an entry velocity, and the interspace is simultaneously flowed through by a gas which exits into the production unit at an exit velocity, wherein the entry velocity is greater than the exit velocity.

The present invention relates to a joint socket (1) for a hip joint prosthesis, with a metal outer shell (2) and with a preferably ceramic inner shell (3). The outer shell (2) and the inner shell (3) are held together with a force fit by shrinkage and are connected to each other by at least one additional form-fit means (4; 5). The at least one form-fit means (4;5) is arranged on the periphery in the equatorial edge region of the joint socket in such a way that, as a result of the shrinkage stress, it forms a sealing operative connection between outer shell (2) and inner shell (3). The present invention further relates to a method for producing a joint socket (1), in which method a metal outer shell (2) is shrink-fitted onto a preferably ceramic inner shell (3), wherein at least one peripheral form-fit means (4;5) in the equatorial edge region of the outer shell (2) engages in a corresponding means of the inner shell (3).
摘要:
A novel approach to dry development of exposed photo resist is described in which a photo resist layer is exposed to a visible light source in order to remove the resist in the areas of exposure. The class of compounds used as the resist material, under the influence of the light source, undergoes a chemical/structural change such that the modified material becomes volatile and is thus removed from the resist surface. The exposure process is carried out for a time sufficient to ablate the exposed resist layer down to the layer below. A group of compounds found to be useful in this process includes aromatic calixarenes.

A test stand arrangement includes at least one electric motor (4) connected to a test specimen for driving and/or loading the test specimen, and a control arrangement for the or each electric motor. In order to be able to create the connection of the drive train and vehicle simulation with the real, vehicle-specific combustion and dynamic behavior of the engine, at least one model for a multi-mass flywheel is implemented in the control arrangement, from which model at least a part of the control requirement for the or each electric motor is calculated and which model contains at least the two masses of the primary and secondary side of the multi-mass flywheel and a substitute model for the or each bow spring, and an algorithm is implemented in the control arrangement that analyzes the model for a multi-mass flywheel by means of an integrated time step method.

The invention relates to a process and an associated apparatus for producing metals and/or primary metal products, in particular pig iron and/or primary pig iron products, in which a metal-containing charge material, in particular in fine particle form, is introduced, using pneumatic conveying, by means of a carrier gas stream, in the form of a stream of medium formed from the charge material and the carrier gas stream, into a melting unit, in particular a melter gasifier, for further processing. According to the invention, the charge material is introduced after the carrier gas stream has been separated off and separately at at least two introduction points, so that at least two partial quantities of the charge material can be introduced independently of one another and continuously or in stacked form.
