[Class 74 (ii)] Relates to the use of knitting-machine needles of the sliding-latdh type, which when deflected at right angles to their longitudinal axes, permit loops to be transferred to other needles in the same or opposing bed. The invention is described as applied to a parallel machine. Hooked needles 3 sliding in tricked beds 2 are provided with independently movable transfer instruments 4 which also serve as slidable latches Each instrument has, formed in its underside, a notch 5 for accommodation at appropriate times of a protuberance 6 on the outer edge of the companion needle. The instruments 4 have pointed extremities 7 terminating in loop-arresting shoulders 8. Adjacent to the shoulder, each instrument is provided at each side with a recess 9 which extends transversely across the stem and is of gradually increasing depth downwardly. The recess terminates at the front in a groove 10, which extends forwardly beneath the point 7. The cheek of each needle 3 is grooved at 10<SP>1</SP> to receive the point of the companion instrument. When transferring is to be done selected needles 3 with their instruments 4 are advanced by the transfer cams until the loops are taken on the points 7. The instruments are then advanced still further, while the needles return empty. In this advanced position, the instrument 4 is prevented from movement longitudinally by the transfer cams, while the cam 12 makes contact with the butt 13, thus deflecting the instrument laterally over a neighbouring needle in the same or the opposite bed. This needle, having been advanced sufficiently, enters the groove 10 and penetrates the loop to be transferred.

Abstract: 1,025,541. Protective switching arrangements. OMNITRONICS Inc. Jan. 10, 1964 [Jan. 29, 1963], No. 1310/64. Heading H2H. A circuit arrangement permitting rapid energization and de-energization of an inductive load such as a relay 15 comprises a switching transistor 13, the relay 15 and a capacitor 14 in a series circuit to which is applied a D.C. potential a resistor 18 being connected in parallel with the capacitor 14 and energydissipating circuit having a resistor 23 and a semi-conducting diode 22 in series connected in parallel with the relay 15 and capacitor 14. A switching pulse applied to the base of the transistor 13 renders it conductive whereupon the heavy current surge flowing through the capacitor 14 rapidly causes energization of the relay 15 and this energization is maintained by the current subsequently flowing through the resistor 18. When the transistor 13 is rendered non- ductive, the energy stored in the magnetic field of the relay 15 is rapidly dissipated in the circuit comprising the diode 22, resistor 23 and the resistor 18 whilst the charge in the capacitor 14 is dissipated in the resistor 18. Since, during the dissipation of the energy stored in the circuit 14, 15 the polarities across the two components are in opposition, inherent protection of the collector of the transistor 13 is provided. In a second embodiment (Fig. 3, not shown), the energy dissipating circuit includes a transistor and a further resistor connected across the capacitor 14, the ohmic value of this further resistor being lower than that of the resistor 18 thus providing a more rapid dissipation of the charge in the capacitor.
