Title: Improvements in and relating to the manufacture of spandex yarn
Inventor: PRIEST MAURICE HENRY
IPC: D01F6/70
Filed: 1962-12-21
Abstract: 1,061,094. Making spandex yarn. COURTAULDS Ltd. Dec. 20, 1963 [Dec. 21, 1962], No. 48275/62. Heading B5B. In the manufacture of multi-filament spandex yarn by extruding a polymeric precursor of the spandex polymer through a multi-hole jet into a coagulating liquor containing a reagent capable of reacting with the precursor to form spandex filaments, the freshly extruded filaments are drawn from the jet through a tube immersed in the liquor, which is straight, open at both ends and coaxial with the jet, the inlet end of the tube being adjacent to the jet, and the liquor is caused to flow concurrently with the filaments through the tube in such a way as to reduce the relative velocity between the filaments and the liquor to a value substantially less than the absolute velocity of the filaments, each part of the yarn being within the tube for at least one second, and preferably for up to 3 to 4 seconds. The linear speed of the yarn leaving the coagulating liquor may be from 5 to 10 times the linear speed of the polymeric precursor through the jet. In the example, a polyester resin made by condensing together ethylene glycol, propylene glycol and adipic acid is reacted with diphenyl methane diisocyanate to form a polymer precursor of a spandex polymer, containing isocyanate groups. The precursor is extruded at a rate of 5 metres per minute through a multi-hole jet into a 50% aqueous solution of ethylene diamine and the filaments issuing from the jet are led into a tube of half an inch internal diameter and 24 inches long submerged in the liquor. The coagulating liquor is caused to flow in the same direction as the filaments are moving by maintaining a difference of half an inch head of liquor over the inlet and outlet of the tube respectively. The dwell time of the filaments in the tube is about 2 seconds. The filaments are withdrawn from the tube and from contact with the liquor on to a take-up roller revolving with a peripheral speed of 40 metres per minute. The process reduces the incidence of adhesion between filaments.

Abstract: 1456848 Incremental tape transport KOKUSAI GIJUTSU KAIHATSU KK 17 Oct 1973 [17 Oct 1972 14 Sept 1973] 48359/73 Heading G5R An incremental digital magnetic tape recorder has tape supply 1 and take-up means 3, Fig. 1, a mgnetic head 4 for recording intermittent digital input signals on the tape 2, torque supply means whereby the tape is held under tension between the supply and take-up means, a deflector 7 having driving means operative, in response to an input signal to be recorded, to displace a push-rod to thereby deflect the tape away from its normal path and hence move a predetermined incremental length of tape past the head 4 towards take-up means 3, and braking means 5 constantly applying a braking force to the tape 2 whereby the tape is held stationary by the braking means against the tape tension when the deflector 7 is in an inoperative tape-undeflected position, the torque supply means constantly applying a torque to the take-up means 3 whereby the latter tends to take up any portion of the tape deflected by deflector 7, with the take-up means 3 having a sufficiently large inertia to prevent the tape from being unwound to any substantial extent from the take-up means during operation of the deflector 7. Torque may be applied to take-up reel 3 by an electric motor or a spring-energized clock mechanism wound manually or by an intermittently operated solenoid. The braking means 5 may comprise a pair of shoes, Fig. 1, means acting on supply reel 1, or means cooperating with head 4, Figs. 5, 11. In a first form of "read-after-write" recorder, Fig. 5, a brake 5a engages a guide roller 6c, a brake 5 engages head 4 and the deflector has a two-armed push-rod 11 pivoted at 12 and moved by device 13. When device 13 is energized to rotate rod 11 anticlockwise the righthand arm thereof engages the tape between head 4 and roller 6b and draws a tape increment rightwards past head 4 for recording thereby, a spring-biased tension arm 9 simultaneously moving so that the tape runs straight between rollers 6a, 6c. Device 13 is then energized to rotate rod 11 clockwise whereby the left-hand arm thereof engages the tape between head 4 and roller 6c to move the tape increment back leftwards past head 4, the signal just recorded being read out during this movement. If the recorded signal is incorrect, direct current may be applied to head 4 to effect erasure. Following the leftward tape movement and reading operation rod 11 is again moved anticlockwise to advance the tape rightwards for take-up by reel 3 whereafter the normal position of Fig. 5 is resumed. A second form of "read-after-write" recorder, Fig. 11, has a similarly operated push-rod 11 carrying leaf-springs 16<SP>1</SP>, 16 operable to engage braking devices 5d, 5c which co-operate with guide rollers 6a, 6b and are provided in addition to a braking device 5 co-operating with head 4. Two discrete tape deflectors respectively engaging the tape between roller 6a and head 4 and between head 4 and roller 6b may be used instead of the two-armed push-rod 11 and single actuator 13.

The lower face of the wafer is then lapped or etched to the desired thickness and a layer of germanium evaporated on to this face. The wafer is then divided into individual transistors 10 each comprising a silicon collector region 22, diffused base and emitter regions 14, 16, conductive contacts 18, silicon oxide layer 20 and germanium layer 24. A contact member 12, for example of " Kovar " (Registered Trade Mark), has a layer 28 of gold electrolytically plated on to its surface. The transistor 10 and the member 12 are placed in contact and heated above the eutectic temperature of the goldgermanium eutectic by passing a current through member 12. Jets of nitrogen are played on to the device during bonding to prevent the formation of oxides. The temperature of bonding is kept below the individual melting points of gold and germanium and, if necessary, below the melting point of the gold-silicon eutectic which may form part of the other contacts of the' transistor. The germanium may be intrinsic or doped, for example, with antimony for an N-type substrate or aluminium for a P-type substrate. The impurity may be deposited as a thin film on top of the germanium layer. The layer 28 may also be formed by vapour deposition and may comprise lead instead of gold.
