Title: Drawing of synthetic organic filaments
Inventor: MUMMERY LESTER RATHBURN
IPC: D02J1/22
Filed: 1963-02-14
Abstract: 986,704. Drawing artificial filaments. E. I. DU PONT DE NEMOURS & CO. Feb. 14, 1963, No. 6008/63. Heading B5B. Synthetic organic polymer filaments which have been collected into a tow are drawn by passing the tow through a bath of a liquid which does not dissolve the polymer, meanwhile spreading the tow while immersed in the bath into a sheet of parallel filaments by passing the tow under tension over solid elements immersed in the bath, for example passing the tow in succession under and over a series of parallel straight round rods or bars fixedly located in the bath, withdrawing the filaments from the bath and then drawing the wet filaments to increase their length. As shown in Fig, 1, tow 1 is passed through aperture 2 in guide plate 3 and into a trough 5 containing a non-solvent liquid 6. Immersed in this bath are eight fixed parallel rods 4 some of which the tow passes under and some of which it passes over. Sets 7 and 8 of identical draw rolls (eight rolls to the set) receive the tow (now spread into a sheet of parallel filaments) over and under alternate rolls after it leaves the bath. Squeeze roll 10 presses the emergent sheet of filaments against the first draw roll 7a (Figs. 2 and 3) mounted with its axis over the trough 6 and its lowermost surface above the bath level so that excess 12 of bath liquid drips back into the bath. From the second set 8 of draw rolls, whose peripheral speed is greater than that of the first set of draw rolls so as to establish the drawing zone 13 between the two sets of draw rolls, the sheet of filaments proceeds to further processing or wind-up. Figs. 2 and 3 show the simultaneous entry of three tows of filaments into the bath and the change in the configuration of each group of filaments or tow from bundle to sheet form, the separate sheets joining to form a single sheet before leaving the bath. The bath liquid may be water which may also contain a small proportion of a lubricant, antistatic agent or softening or swelling agent. The rods may be polished stainless steel or polished or mattefinished chrome-plated rods. The filaments may be composed of polyethylene terephthalate, polyamides or polyacrylonitrile. The invention improves the uniformity of the drawing of the filaments and consequently the uniformity of their dye take-up. Specification 543,466 is referred to.

Patent GB-1302763-A (GB)
IPC: H03B9/12
Filed: 1970-02-09
Abstract: 1302763 Bulk negative resistance devices GENERAL ELECTRIC CO 9 Feb 1970 [27 Feb 1969] 6136/70 Heading H1K A solid state electron transfer device with a distance L between anode and cathode contacts and a product n 0 L, where n 0  is the equilibrium carrier concentration, less than that required to support domain formation, is so constructed that when suitably biased electron injection from the cathode is limited to such an extent that the field can be maintained above the threshold level at which negative resistance occurs substantially throughout the anodecathode gap. The device is preferably made of uniformly doped N type GaAs with the product n 0 L between 10<SP>10</SP> and 10<SP>12</SP>/cm<SP>2</SP>. an operated at 2-3 times the threshold field through InP, CdTe, or ZnSe may also be used. Limitation of electron injection is achieved in one or a combination of the following ways: (i) The cathode e.g. of Au forms an electron blocking Schottky contact with the semiconductor. (ii) A similar blocking cathode is formed by a limited diffusion or ion-implantation step. (iii) A ohmic cathode e.g. of Zn contacts the body through a diffused or epitaxial P type GaAs layer a few Á thick; a layer of Ge, or GaP on which the body can be epitaxially grown, or a polymer layer; or an intrinsic, very lightly doped to compensated GaAs layer, which may be produced by doping with Fe, inplantation of hydrogen ions with energises >50 KeV, or by suddenly lowering the substrate temperature at the end of an epitaxial process for forming the N type GaAs body. (iv) By providing a light permeable e.g. tin oxide, or perforated blocking cathode whereby the body can be illuminated e.g. with a laser, to provide a controlled supply of electrons. (v) Restricting the contact area of an ohmic cathode either by tapering the body using standard shaping techniques or by depositing the cathode material over a multi-apertured silica, plastics or photoresist mask to provide a plurality of small interconnected contact areas. One way of forming the mask is to deposit masking material over uniformly distributed minute particles which are subsequently removed. Small resistors may be formed between individual contact areas and the interconnecting material to reduce localisation of injection arising from thermal runaway. Series-parallel arrangements of devices may be used for increased power in oscillator or amplifier applications.
