Patent ES-375297-A1 (ES)
Title: Bipolar circuit device
IPC: H03K17/72
Filed: 1970-01-09
Abstract: A protective arrangement in which a bipolar circuit device is connected across the terminals of a voltage source with voltage monitored through a voltage regulator connected to the source. The bipolar device contains two transistors of opposite conductivity type interconnected so as to exhibit low internal resistance when the output voltage from the source lies within predetermined operating limits. When the output voltage from the source exceeds a predetermined limit, due to failure of the voltage regulator, for example, the internal resistance of the bipolar device drops sharply and substantially short-circuits the terminals of the generator. The change in resistance is made permanent through destruction of the transistors as a result of heat dissipation.

Title: Detection of defective knitting needles of a knitting machine
IPC: D04B35/18
Filed: 1974-09-18
Abstract: A method and apparatus for detecting defective knitting needles in a circular knitting machine wherein the knitting needles are advanced along a circular path between a light source and upper and lower vertically spaced photoelectric detector devices. The direction of the light beams from the source to the two photoelectric devices is inclined at an angle to the tangent of the circular path at the beam intercept with the circular path, such that the advancing needles pass successively through the beams and a shadow of the hook end of each needle is cast on the upper photoelectric device before any shadow of any other part of the needle is cast on the lower photoelectric device, when a nondefective intact needle enters the beams. Needles with broken off hooks or closed needle latches cause a shadow to be cast on the lower photoelectric device before any shadow reaches the upper photoelectric device to activate an alarm and/or stop the knitting machine. A third photoelectric device may be positioned to receive a shadow of a different needle from the one being inspected by the upper and lower photoelectric devices to detect needles broken off too low to cast a shadow on the lower photoelectric device.
