A turbine blade or vane for use in a gas turbine is to have as long a service life as possible at high strength. To this end, the turbine blade or vane, according to the invention, has a basic body which is formed from a strengthened cast ceramic material and in which a number of reinforcing elements are placed.

A lift belt (12) for a lift installation comprises a belt body (15) in which a tensile carrier arrangement (14) with several tensile carriers (14.1, 14.2) for transmission of a tension force in longitudinal direction of the lift belt is arranged. A profile body (16) which spaces these tensile carriers from one another is arranged between adjacent tensile carriers (14.1, 14.2) of the tensile carrier arrangement (14). <SDOCL LA=EN> 12 Claims 1. Lift belt (12) for a lift installation, with a belt body (15) in which a tensile carrier arrangement (14) with several tensile carriers (14.1, 14.2) in the form of strands or cables for transmission of a tension force in longitudinal direction of the lift be lt is arranged, characterised in that a profile body (16) is arranged between adjacent tensi le carriers (14.1, 14.2) of the tensile carrier arrangement (14) and spaces these tensil e carriers from one another. 2. Lift belt according to claim 1, characterised in that a respective profil e body (16) is arranged between several, preferably between all, tensile carriers of the tensile carrier arrangement (14). 3. Lift belt according to claim 2, characterised in that all profile bodies (16) have the same cross-sectional shape. 4. Lift belt according to claim 2, characterised in that at least two profil e bodies (16) have different cross-sectional shapes. 5. Lift belt according to any one of the preceding claims, characterised in that a profile body has a substantially circular, oval (16.1), T-shaped, double-T-shaped (16.3), U- shaped, triangular or quadrangular (16.2) cross-section. 6. Lift belt according to any one of the preceding claims, characterised in that a profile body extends in longitudinal direction ofthe lift belt (12), particularly substantially over the entire lengthof the lift belt. 7.

The aim of the invention is to provide a highly durable, high-strength thermal shield element for the interior lining of the combustion chamber of a gas turbine. For this purpose, the thermal shield element comprises a base produced from a solidified cast ceramic material into which a plurality of reinforcing elements are integrated.

A control box includes a shell, a display hole, an active member, an indicating member and an interlinking member. The display hole is formed in the shell. The active member has a turn-on end and a turn-off end and is pivotally connected with the shell so as to seesaw. The indicating member is movably disposed in the shell and has a first identifiable portion and a second identifiable portion. The interlinking member is connected between the active member and the indicating member to drive the indicating member to move. Accordingly, when the active member seesaws under the effect of an external force, the indicating member is driven by the interlinking member to show the first identifiable portion or the second identifiable portion in the display hole.

A method and a system for destruction of an undesirable formation in a mammalian body are described. The invention is based on inserting a probe into mammalian body; said probe is electrically connectable to a control unit and upon bringing the probe in physical contact with the formation supplying pulses of energy from the control unit to the probe in order to destroy the formation. The invention further comprises counting amount of pulses being supplied to the probe and establishing a remaining service life of the probe by subtracting the amount of pulses being supplied to the probe from an amount of pulses corresponding to initial service life of the probe. The treatment session is automatically terminates as soon as amount of pulses being supplied to the probe approaches at least a fraction of the established remaining service life of the probe. The established remaining service life of the probe is stored for new treatment session. Delivery of pulses automatically terminates when the remaining service life is exhausted and use of such probe becomes impossible.

A universal joint assembled in a drill string transfers torque between two components where the shafts of the components are not completely aligned. The universal joint includes two members each with pin connections on one end and axially extending arms on the other end. The axially extending arms intermesh when the members are assembled defining a closed cavity between the arms. The cavity retains a ball bearing held between two seats. The universal joint when assembled to portions of the drill string at the pins on each end transfer torque by intermeshing of the teeth. Axial force is transferred through the seats holding the ball bearing.

A hoisting machine and an elevator system including the hoisting machine are provided. The hoisting machine includes a measuring arrangement for determining the position and / or movement of the rotor of a hoisting machine. The measuring arrangement includes a magnetic band whose magnetic property is so implemented that it varies in the longitudinal direction of the band.

A humidifier includes a shell, a fixing bracket, an atomizer, and a control circuit assembly, and the fixing bracket is disposed in a containing cavity of the shell and divides the containing cavity into a first isolating cavity and a second isolating cavity opposite to each other; the control circuit assembly is disposed in the first isolating cavity, and a solution is contained in the second isolating cavity; the atomizer is positioned in the solution of the second isolating cavity and electrically connected to the control circuit assembly. The control circuit assembly controls the atomizer to atomize the solution.
