  • Patent number: 6834062
    Abstract: The present invention provides a method and apparatus for controlling laser power, using at least two Brewster windows which are aligned along an axis which is parallel to the direction of the laser beam and which are rotatable around said axis, wherein the first Brewster window is rotated in one direction and the second Brewster window is rotated in the opposite direction. Preferably, both Brewster windows only have to rotate each through +/−45° to control transmission of the laser beam from maximum to minimum.
    Type: Grant

  • Patent number: 5950483
    Abstract: A hydrokinetic torque converter includes an impeller driven by an internal combustion engine, a turbine coupled to an output shaft, and a stator that can be blocked in one rotational direction, which together form a converter circuit filled with converter fluid, which is supplied from a supply container by a hydraulic supply system through supply lines and return lines, at least one of which is in flow connection with at least one opening, which is provided on a separating wall located between the turbine hub and the associated casing cover of the converter housing and connects that line to a chamber defined by the casing cover and an adjacent converter element. The separating wall is integrally constructed with the casing cover and preferably acts in the radial extension area of the turbine hub as an axial support for supporting the turbine hub against axial movements.

  • Patent number: 5350127
    Abstract: A process and device for monitoring the bobbin thread on stitch-forming machines, on the bobbin of which a residual amount of thread is wound in a winding direction opposite the direction of winding of the principal amount of thread, is to ensure that a first control function will be generated at the beginning of consumption of the residual amount of thread, and a second control function is generated nearly without delay in the case of thread end or thread break. To achieve this, two signal patterns are received with a phase shift from a bobbin acting as a signal generator, and the first signal function is generated in the case of a deviation of the actual phase shift from the desired phase shift. If only one signal pattern is received, this first control function is also generated if its signal sequence deviates from a reference signal sequence. The second control function is generated if a stoppage of the bobbin lasts longer than a predeterminable number of stitches.

  • Patent number: 5107779
    Abstract: To recognize missed stitches during the operation of a sewing machine, a function, which represents the tensile force of a thread fed into a stitch-forming device depending on the angle of rotation of the main shaft, is scanned in its entirety during each revolution period of the main shaft for selected characteristics without regard to the location of this characteristic within the revolution period. The characteristics found are measured in order to obtain for each characteristic an analytical value that is compared with the corresponding analytical value from at least the last preceding revolution period to form the difference of the two analytical values. If this difference exceeds a predeterminable value, a decision corresponding to a missed stitch is made.
