摘要:
The system comprises a therapeutic bed, a chamber, a combined head, a motional apparatus, a therapeutic power source, an imaging power source, a vacuum degassor, and a controller. The therapeutic transducer, the imaging transducer, and a rotator, together form the combined head. The combined head may also include an actuator. The rotator and actuator move the imaging transducer relative to the therapeutic transducer. The therapeutic transducer produces high intensity focused ultrasound, and treats target tissue in the body.

The invention relates to a closing assembly for closing the gap remaining between the first and last blade of a blade ring that is inserted into a peripheral groove of turbomachinery. Said assembly comprises at least two parts each of which can be hooked onto projections that form an undercut in said peripheral groove and comprises a securing element, which secures the parts from becoming detached from the peripheral groove. To provide a closing assembly for closing the remaining gap, which can be simply and cost-effectively detached and which reliably withstands high mechanical stress, the securing element is mounted to rotate about its longitudinal axis between the two parts and has a key head and a web. The web of the securing element can be positioned by rotation is such a way that to fit the parts in the peripheral groove, said parts can be displaced in relation to one another and to secure the parts from being detached from said groove, the web of the securing element can be placed against at least one lateral face of one of the parts.

The invention relates a method for improving the hot-starting behavior of a turbomachine. By virtue of the setting of a radial gap formed between a brushing edge of a blade profile and a guide face lying opposite this, in which setting a guide ring forming the guide face can be acted upon with a coolant, the hot-starting behavior can be improved, in that the guide ring is cooled before the start of the machine.

The invention relates to a closing assembly for closing the gap remaining between the first and the last blade of a blade ring that is inserted in a peripheral groove of a turbo machinery, said assembly consisting of at least two lateral parts, at least one of which can be hooked onto a projection that forms an undercut in said peripheral groove and at least one securing element, which secures the parts from coming detached from the peripheral groove. To provide a particularly reliable closing assembly, the securing element is configured as a pin, joining the parts of the closing assembly in a non-positive fit.
