Patent JP-3512248-B2 (JP)
IPC: H02M1/088
Filed: 1994-10-21
Granted: 2004-03-29
Abstract: A method and a device are specified for driving a series circuit of power semiconductor switches (2). In this case, the voltage load on the individual switches in the series circuit is compensated for in that the voltage (Uce1 ... Ucen) across each switch in the series circuit is measured as the control variable and the switching times are changed on the basis of this measured voltage such that the voltage load is essentially of equal magnitude for all the switches during switching. In addition, the measured voltage can be used to influence the magnitude of the control voltage (Ugeoff1 ... Ugeoffn) in the switched-off state such that the voltages across the switches when they are switched off are essentially of equal magnitude. The advantage of the invention can be seen in the fact that the voltage load on the individual semiconductors can be compensated for not only during switching but also when they are switched off. In addition, the regulation also compensates for influences of parameter differences and changes as well as influences from the circuitry. In consequence, the switches can be used optimally in terms of both power and frequency. <IMAGE>

Abstract: A method is provided for separating hydrogen fluoride (HF) from a mixture comprising HF complexed with an aromatic ketone in which the keto carbon atom is directly bonded to an aromatic ring carbon atom, e.g., 4-isobutylacetophenone, by adding a carboxylic acid anhydride, e.g., acetic anhydride, to the mixture while maintaining the mixture at conditions sufficient to sustain a reaction between the anhydride and the HF to form the corresponding acyl fluoride, e.g., acetyl fluoride, and carboxylic acid, e.g., acetic acid, and separating the acyl fluoride from the mixture. The method is conveniently carried out in a stripping column near the top of which the mixture comprising aromatic ketone and HF is fed and below which the anhydride is fed. Between these feed points, the uncomplexed HF is stripped from the mixture, while below the anhydride feed point or points, the anhydride reacts with the complexed HF to form the acyl fluoride which is stripped from the mixture, and the carboxylic acid. The separation method may be integrated with the production of the aromatic ketone by the Friedel-Crafts acylation of an aromatic compound, e.g., isobutylbenzene with an acyl fluoride, a carboxylic acid anhydride, a free carboxylic acid, or a mixture of the foregoing reactants, using an excess of HF as catalyst, to produce the mixture comprising aromatic ketone and HF to be separated, and to which the separated HF and in some cases the acyl fluoride may be recycled.

Abstract: Driving shield machines are known in the construction of tunnels through unconsolidated rock; in these known machines, the working face is shored up by supporting fluid in a working chamber of the driving shield machine sealed off from the tunnel. With these known driving shield machines, unconsolidated rock can fall out of control into the entire working chamber if the working face collapses during the tunnelling process and thus seriously jeopardize the safety of men working in the tunnel. To reduce this risk considerably, the driving shield machine according to the invention is provided with a partition (40) which can slide longitudinally and divides the working chamber (3) into two partial chambers (3', 3''). An aperture (52) is provided in the partition (40) and a tunnelling arm (10) extends through the aperture, which is designed so as not to restrict the mobility of the tunnelling arm (10). Since the partition can slide into a position adjacent to the working face, the latter can be given additional mechanical support if a collapse seems likely, without any need to interrupt the tunnelling process and provide support using the support fluid.

The body being split allows the aperture to be enlarged to facilitate insertion of the catheter. The connector further includes a bayonet assembly for twist locking the connector in the opening of the fluid transfer device, and complementary wing elements radially projecting adjacent to the slit for clamping together and against a region of the fluid transfer device. So clamping the complementary wings prohibits the connector from being removed from the opening, and generates a compressive force to secure the catheter to the port of the fluid transfer device.
