  • Patent number: 7823392
    Abstract: An arrangement for a turbomachine combustion chamber is disclosed. The arrangement includes a chamber end wall pierced by at least one substantially circular opening, a deflector mounted from the downstream side of the chamber end wall in the opening by an annulus, an injector system associated with the opening and including an annular bowl that is flared downstream, passing through the opening, and a pinch ring that cooperates with the annulus to allow the injector system to shift off-center relative to the chamber end wall. The deflector includes an annular collar extending radially inwards. The bowl of the injector system includes at its downstream end an outwardly-open annular groove radially in alignment with the collar of the deflector in such a manner as to enable it to retract into said groove when the injector system shifts off-center relative to the chamber end wall.

  • Publication number: 20100125010
    Abstract: A hockey stick for training a person in stick handling, having elongate upper stick portion, an elongate lower stick portion, an elongate coupling member, and an elongate middle stick portion. The elongate upper stick portion is configured to be gripped by a control hand of the person. The elongate lower stick portion has a blade member extending outwardly therefrom. The elongate coupling member rigidly couples the upper stick portion to the lower stick portion. The elongate middle stick portion is positioned between and collinear with the upper stick portion and the lower stick portion and is configured to be gripped by a directional hand of the person. The middle stick portion is rotatably coupled to the elongate coupling member so that rotation of the upper stick portion causes the lower stick portion and the blade member to rotate without rotating the middle stick portion gripped by the directional hand.

  • Patent number: 7516035
    Abstract: A method serves to correct drift phenomena, in particular creep effects, occurring in an electronic balance that has a measuring transducer through which a measuring signal is formed which is representative of a load applied to the force-measuring device. The measuring signal is delivered by way of an analog/digital converter to a signal-processing unit that is supported by at least one processor, said signal-processing unit being capable of compensating drift deviations, for which purpose the signal-processing unit, via the processor, accesses drift parameters that are stored in a memory unit and serve as basis for calculating a time-dependent correction value by which the drift error of the measuring signal (ms) is corrected.
