    Abstract: A sewing machine includes a stud carried by a journal surrounding a tubular needle bar having a lateral opening. A link connected to the journal normally drives the needle bar when the stud is engaged within the needle bar opening. A disconnecting rod within the tubular needle bar is axially displaceable and includes a ramp engageable with a control member, also within the needle bar, to drive the stud from the needle bar opening and thereby disengage the journal from the needle bar.

    Abstract: In order to obtain, in an electronic balance, ranges which are in a predetermined ratio, for example 1:10, there is provided a measuring arm provided with strain gauges adapted to measure the deformation of this arm when it is subjected to a constraint or force. Between the arm and a knife-edge there is disposed a measuring annulus likewise provided with strain gauges adapted to measure the deformation of this annulus when it is subjected to a weighing force. The balance is operated in such a manner that the force or mass of the weight to be measured at the moment of weighing is exerted firstly on the arm via the annulus, until the arm contacts the abutment. This determines the small measuring scale. If the weight is higher than this value, the force is subsequently exerted solely on the annulus which presents a resistance in the region of 10 times greater and determines the second measuring scale.

    Abstract: PCT No. PCT/CH84/00015 Sec. 371 Date Oct. 10, 1984 Sec. 102(e) Date Oct. 10, 1984 PCT Filed Feb. 3, 1984 PCT Pub. No. WO84/03110 PCT Pub. Date Aug. 16, 1984.The lateral displacement or oscillation of a sewing machine needle bar is controlled by a permanently installed servomotor-driven cam operated in coordination with a second similarly installed servomotor-driven cam controlling the displacement of the fabric feed dog. Manipulation of the faces on the two cams, in a synchronized manner, allows numerous stitch patterns to be achieved according to the amplitude and direction of displacement of the needle bar and feed dog pursuant to the positioning of the faces on the two cams by their respective servomotors.

    Abstract: The needle bar (1) engaged in a pivoting cradle (2) is integral with a journal (3) connected by a connecting member (8) to a link (4) driven from the drive shaft (12) of the machine. In order to permit the head (23) of a loop holding member (25), mounted in the pedestal of the sewing machine, to engage in a loop (29) of the needle thread (27) during the ascending course of the needle (22), whatever may be its decentration, the connecting member (8) is formed by a bent extension of the crank pin of the link (4) engaged in a bore (7) of the journal (3).
