  • Patent number: 6091731
    Abstract: Arrangements for controlling a data switching network fabric and for synchronizing duplicate modules of such a fabric. A control complex, for determining new virtual connections to be established, and for disconnecting existing virtual connections, is connected through data links to the network fabric of a data switch. The network fabric has internal control processors. The control complex communicates with these processors by sending control packets over a dedicated internal ATM link and virtual connections to these internal processors to control their establishment and disconnection of user virtual connections. Duplicate modules of the data switching fabric receive identical packets and, when synchronized, transmit identical packets at the same time. The synchronization process is implemented by data links between the control processors of the duplicate fabrics to report progress on the step by step synchronization of internal queues.

  • Patent number: 5771828
    Abstract: A sewing or embroidering machine is provided with a thread-cutting device and a signal transmitter representing the angular position of the arm shaft. The drive of the catch thread device is acted upon as a function of the signals generated by the signal transmitter according to a movement program stored in a memory. The path data of this movement program are in a defined relation to the rotary movement or the current angular position of the hook. The drive of the catch thread device is part of a regulating device operating as a cascade control or of a control device operating as a path plan control. Due to the exact agreement in time between the movement process of the catch thread device and the course of the rotary movement of the hook, the thread-cutting process can now also be carried out during the phase of deceleration of the sewing machine, so that an inexpensive, uncontrolled motor can now be used to drive the sewing machine.

  • Patent number: 5651324
    Abstract: In a process and device for monitoring a residual amount of hook thread in a double thread lockstitch sewing machine, a bobbin is used, which is divided into a large clamber and a small chamber due to the arrangement of a middle flange, wherein the small chamber accommodates the residual amount of thread. An abrupt reduction in the speed of rotation of the bobbin, n.sub.S, takes place dating sewing at the time of the transition from the principal to the residual amount of thread as a consequence of the abrupt change in the thread pull-off site in the bobbin.

  • 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: 5199365
    Abstract: A thread monitoring arrangement for monitoring sewing thread at different areas along the path of the thread inducing a switching process for signalling or stopping the sewing process upon the occurrence of thread disturbance. The thread monitoring arrangement includes first sensor units positioned in an area between a thread reserve and an associated tensioning device. Second sensor units are provided in the area between the tensioning device and the associated stitch formation site for sending signals in the case of thread disturbance. A monitoring switching arrangement is provided, evaluating signals from the sensor units differently to induce different switching processes, either alerting the operator or stopping the sewing process, after a predetermined time or immediately.

  • Patent number: 5159890
    Abstract: A sewing machine is provided with a device for stopping the drive in the case of a thread disturbance. The device has a light source, a first light guide device for transmitting the light beams to the monitoring point, a second light guide device, via which a signal can be sent to a receiver in the absence of thread at the monitoring point, and a control unit for signal evaluation and to report a thread disturbance, even in the case of maximum deflection of the thread at right angles to the pull-off direction, only when a thread disturbance does really exist. To achieve this, the first light guide device is designed, on its side facing the thread, in a plane perpendicular to the thread pull-off direction, with a radiation outlet which extends preferably in the horizontal direction. The first light guide device causes light beams to be sent over the maximum range of movement of the thread at equal radiation intensity over an entire radiation cross section.

  • 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.

  • Patent number: 5018465
    Abstract: The control circuit of a catch thread device has a counter for the main shaft of the swing machine. The counter counts the number of revolutions of the main shaft 26 during the reception of one of at least two signal intensities and is reset to its initial value when this signal intensity changes to the other signal intensity. When a predetermined maximum number of revolutions is reached, the counter emits a signal indicating a thread fault.

  • Patent number: 4624441
    Abstract: A pilot-operated valve suitable for pontoon inflation arrangements contains a main valve poppet urged against a valve seat connecting the inlet and outlet ports of the valve. A portion of the inlet pressure urges a piston carrying the valve poppet away from the valve seat, but this is resisted by a portion of the inlet pressure acting in a pressure volume on the opposite side of the piston. By way of an electrical signal, a manual operation or pneumatic pressure, a pilot valve is opened so as to relieve the pressure on the main valve poppet tending to close it. This allows the valve to open and fluid to pass through the valve assembly. Once the pilot valve has opened pressure from the inlet is applied within the pilot valve to hold it in the open position until the inlet pressure has been substantially reduced. Operation of the pilot valve also allows inlet pressure to be applied to a crossover connection of the valve.

  • Patent number: 4561468
    Abstract: A valve is formed with a valve chamber and with an entrance port, a first exit port and a relief exit port each of which communicates with the chamber. A valve member is movably mounted within the chamber, and a pair of valve seats is mounted within the chamber for cooperation with the valve member, one of the seats being movable. The valve member and movable seat are biased in such a manner that the valve is normally seated with respect to both seats. When fluid in the entrance port exceeds a certain crack pressure, the movable seat moves away from the valve member and the fluid flows out the relief exit port. To stop flow out the relief exit port without creating a pressure surge, the valve member, actuated by a control, seats against the movable seat and at the same time moves away from the other seat so that the fluid continues to circulate through the first-named exit port.

  • Patent number: 4004258
    Abstract: A position indicating pulse latching solenoid has a plunger of paramagnetic steel, movable between two stops of similar material, and fixed permanent magnets which impart a flux to the plunger causing it to adhere to the stop to which it is moved, movement being accomplished by a respective winding about each stop which when excited by an electrical pulse momentarily exerts an attractive force on the plunger. A reed switch senses the momentary flux generated by the excited winding at a leakage gap near one of the stops and also determines whether the flux imparted to the plunger by the permanent magnets has shifted with the plunger to or away from the gap to indicate plunger position.
