摘要： An SCR motor speed control system having a capacitor for triggering the SCR into conduction is provided with circuitry for limiting the top speed of the motor by sensing the armature back EMF generated during the non-conducting period of the SCR to determine the motor speed. When the speed is above a predetermined threshold value, a transistor is turned on to short circuit the charging path of the capacitor.

摘要： A controller to permit a sewing machine operator to control a sewing machine drive motor from control members located in close proximity to the needle bar. Means are provided to permit the operator to select the sewing speed and the needle stop position prior to commencing the sewing process. The operator may thereafter control the sewing process by light finger pressure applied to the control members without attention being distracted from the work feeding area. The operator may suspend the sewing process by removing pressure from the control members. The sewing machine will thereafter stop with the needle bar in the selected position. A reset circuit is provided to prevent the operator from unintentionally actuating the sewing machine drive motor.

摘要： A method of forming an eyelet end buttonhole pattern having two spaced apart rows of zig zag stitches joined at one end by a generally circular pattern of zig zag stitches includes first forming a single stitch in the eyelet end, then feeding the fabric in the forward direction until the stitch forming point is at the other end of the buttonhole pattern from where the initial stitch was placed. A side bar is then stitched, beginning in reverse, proceeding around the eyelet end, then in a forward direction to the other end of the pattern. The feeding is then reversed and the stitching retraces the buttonhole pattern in the opposite direction. Barring stitches are then sewn, to close and finish the buttonhole pattern with a square end.

摘要： A sewing machine is disclosed in which electromechanical actuators are incorporated. By selectively supplying power to position the electromechanical actuators, the stitch forming instrumentalities of the sewing machine may be operatively controlled. In order to reduce heat dissipation within the sewing machine under abnormal conditions where the actuators are locked for long periods of time, the sewing machine main drive motor motion is monitored. After a predetermined period of inactivity of the sewing machine main drive motor, the power which can be supplied to the actuators is limited.

摘要： An electronically controlled sewing machine includes an arrangement for utilizing the feed override control to effect a feed balancing function for a pattern having both directions of feed. To effect the balancing function, those patterns which have both forward and reverse feed are "flagged" for recognition by the sewing machine control system. When such a pattern is being sewn, the function of the feed override control is changed to perform the balancing function. Accordingly, when the feed override control is enabled, a fixed increment is added to all forward feeds in the pattern and the feed override control is utilized to attenuate only the forward feeds, to effect a balanced condition.

摘要： A contact-free electrical pulse generator, that utilizes a Hall effect device and a permanent magnet to generate lines of flux and provides two stable output states when cooperating with a flux conducting cam having a stepped peripheral circumference mounted on a rotating shaft is disclosed. The flux conducting cam enhances the flux density imposed upon the Hall effect device when the high portion of the cam becomes proximate the Hall device. The concentrated flux lines flowing through the Hall device changes the state of the device in accordance with the preselected angular positions of the rotary shaft.

摘要： Apparatus for measuring the total internal resistance of a multicell battery having positive and negative terminals employs a first transistor device having an input and an output and having mutually exclusive conductive and non-conductive electric states. An arrangement of resistances is connected in series with the device to form a network. The network is connected between the positive and negative terminals. An operational amplifier has an output connected to the input of the device and first and second inputs. The first input is connected to the network at a point connected to both of the device and the arrangement. A square wave signal alternating between a positive voltage and ground on alternate half cycles is applied to the second input. The device is in the conductive state when the alternating voltage is positive and is in the non-conductive state when the alternating voltage is at ground. The network conducts no current when the device is in the non-conductive state and conducts a current of constant value when the device is in the conductive state. The voltage appearing between the terminals as a result of the current in the network is monotonically related to the internal resistance of the battery.
