C. source G, Fig. 1, being dependent directly upon the pressure applied by a stylus 5 to one or both junctions. The device may be used in a microphone in which a diaphragm M is coupled directly to either a single stylus Fig. 3 (not shown) or to a pair of styli (S 1  S 2 ,) Fig. 5 (not shown) which move in opposite directions for a given diaphragm displacement due to the pivotal mounting (D r ). A standing bias pressure is applied both styli, and an increase in collector current results from an increase in pressure on the collector junction or from a decrease in pressure on the emitter junction. A similar double stylus arrangement may be used to extract stored digital information from a torsional delay line Fig. 6 (not shown). With a planar transistor, the stylus is applied either through the protective coating of the transistor surface to a point where a junction meets the surface Figs. 7 and 8 (not shown), or else directly to the emitter portion (1), Fig. 9 (not shown) in which case the emitter junction (7) should be no more than 0À5 microns from the surface, and the collector junction (5) no more than 1 micron.

Title: Yarn crimping method and apparatus
IPC: D02G1/12
Filed: 1972-08-10
Abstract: 1373725 Crimping yarns JOSEPH BANCROFT & SONS CO 10 Aug 1972 37458/72 Heading D1F In the chamber of a stuffer-box yarn crimping apparatus, a driven single choke roller or a pair thereof, disposed at the juncture of crimping and heating (heat-setting) zones with the axis or axes of rotation parallel to the axes of yarn feed rolls at the inlet to the chamber, is positively driven independently of the pressure exerted thereon by the core of compressed crimped yarn in order to control independently the pressure on the core in the heating zone. Variable additional choke apparatus at the exit of the heating zone may engage the core to control the back pressure therein in this zone. As shown, yarn Y drawn from a package 12 and through a tension gate 14 passes over a guide 16 of a traverse 18 to be distributed along the nip of feed rollers 20 by which it is forced into a crimping portion 26 (zone A) wherein it is formed into the core of yarn. The core is gripped and advanced by toothed choke rollers 32, 34, which isolate the pressure in zone A from that in the subsequent heating zone B. Traverse 18, and rollers 20, 32, 34 are all driven from motor 22 through gearing and/or belt and pulley transmission, but similar speed relationship therebetween may be provided by separate power sources (not shown). The heating portion of the crimping chamber is provided by a cage construction comprising rails formed by matching ribs 40 in half-sections 42, 44, each having a heater (not shown). A cooling zone is provided by bars 46 effective as continuations of ribs 40 to minimise frictional resistance to passage of the core therethrough. A core retarding element in the form of a choke rake 48 is pivotable under the control of adjustable weight 54 so that tines 50 can be urged between bars 46 to maintain a desired back pressure on the core in the zone(s) above rollers 32, 34. Pivotal movement of a sensing frame 56 resting on the upper end of the core controls a rheastat 60 to adjust correctively the speed of motor 70 (driving mechanism for winding crimped yarn into a package 68) so as to maintain within limits the position of the core in the chamber.
