摘要： A linear motor construction in which a plurality of parallelpiped shaped permanent magnets are retained within an easily molded spool having an axial bore formed through the axis thereof. A coil which may be electrically excited is wound about the spool and produces a magnetic field when excited, which reacts with the field produced by the permanent magnets to cause linear motion in a ferro-magnetic, cylindrical armature which is slidably contained within the axial bore.

摘要： A pump for needle threading is disclosed having a housing with a recess therein, an elastomeric diaphragm stretched across said recess forming a pump cavity in which the medium being pumped is circulated, and inlet and outlet valves. An electronically controlled linear actuator is attached to the diaphragm within the pump cavity thereby allowing compactness in the construction of the pump and improved heat dissipation from the linear actuator.

摘要： A circuit which limits the maximum permissible speed of a sewing machine motor when specific stitch patterns are selected. Electronic signals from a means for sensing the selected stitch pattern are analyzed by the circuit to control the operation of a relay which connects a resistance in series with the sewing machine motor to reduce the maximum speed at which the drive motor may be operated.

摘要： A pump is disclosed having a housing with a recess therein, an elastomeric diaphragm stretched across said recess forming a pump cavity in which the medium being pumped is circulated, and inlet and outlet valves. An electronically controlled linear actuator is attached to the diaphragm within the pump cavity thereby allowing compactness in the construction of the pump and improved heat dissipation from the linear actuator. The pump fits within the frame of a sewing machine and creates an air vacuum for assisting in needle threading.

摘要： A low bobbin thread supply alarm in which a bobbin case is fitted with lever pivoted thereon and carrying a permanent magnet for travel to the hub of the bobbin. An arm overhanging the bobbin case and bobbin carries a Hall generator in a portion thereof overlying the hub of the bobbin. The lever and permanent magnet carried thereby is urged by an electromagnet supported externally of the looptaker toward and away from the hub of the bobbin at suitable intervals. When the lever pivots greater than a given amount due to depletion of thread on the hub of the bobbin the permanent magnet on the lever will trigger a voltage change on the Hall generator which may cause an appropriate alarm to provide a warning of a low thread condition.

摘要： The back EMF generated in armature coils is substantially balanced by causing the coils located a greater distance from the axis of rotation of the armature to have fewer turns than the coils located closer to the armature axis of rotation. Alternatively, rather than decrease the number of turns in the coils, the same balancing affect can be achieved by increasing the electrical resistance of the coils located a greater distance from the armature axis of rotation.

摘要： There is disclosed a sewing machine having a needle bar gate vibrating mechanism whereby the sewing machine is adapted to produce zigzag stitches. The needle bar gate vibrating motion is obtained through the use of two spaced apart circular magnets mounted on a rotating shaft of the sewing machine and having disposed between them a pair of bar magnets operatively connected to the needle bar gate, the polarization of the magnets being such that one of the circular magnets exerts attractive force on the bar magnets while the other circular magnet exerts repulsive forces. As the shaft rotates these forces reverse, resulting in the imparting of vibratory motion to the needle bar gate.
