Title: Extruder and spinning head
IPC: B29C48/465
Filed: 1970-02-16
Abstract: 1289125 Combined melt spinning extruder and spinning head JAMES MACKIE & SONS Ltd 18 Feb 1970 [25 Feb 1969] 10084/69 Heading B5B A combined extruder and spinning head for the melt spinning of synthetic organic thermoplastic materials to form filaments comprises a feeding mechanism at the base of the extruder in the form of fluted rollers 1 and 2 mounted on shafts 3 and 4 respectively which are geared together and driven from a common drive (Fig. 1, not shown). The rollers are located at the base 8 of the extrusion chamber to which granular material to be melt spun is fed at either side in the direction of the arrows 9 by means of shoots (not shown). The rollers 1, 2 rotate in the direction of the arrows 10 to feed the granular material upwardly through the region 12 of the extrusion chamber. The material then passes through the heating zone 14 heated by plates 16 fitted to the outsides of the walls 17 and by a heating element 18 located within the central partition 15 of the zone 14. The granules gradually melt while passing between the zones 12 and 14 and any gases evolved escape through the vents 19. The molten material in the zone 14 is forced upwardly through the zone 14 and into and through the spinning head 20 when the temperature is maintained by the heating plates 21. The rollers 1, 2 extend for effectively the whole of the length of the crosssection of the chamber (Fig. 3, not shown) so as to exert a substantially uniform pressure on the material in the zones 12, 14 and 20, whereby uniform extrusion of the melt through the orifices 25 of the spinneret plate 30 (Fig. 4) is ensured. The filaments 26 thereby formed are cooled and solidified by streams of air directed on to the bundle of filaments by the nozzles 27 which are provided with slot apertures parallel to the spinneret plate 30 and extending along the length of the plate. The filaments are drawn upwardly by take-up roller (not shown). As shown in Fig. 4, the array of extrusion orifices in the spinneret plate 30 is many times longer than it is broad (e.g. 10 times or more longer) and the major axis of the array is parallel with the axes of the rollers 1, 2. The number of orifices in the spinneret plate may, for example, range from 16,000 to over 30,000. The length to breadth ratio of the array of orifices must be at least 3 : 1 and preferably at least 9 : 1. The extruder may be provided with a single feed roller eccentrically mounted in the bottom of the extrusion chamber instead of being provided with two feed rollers. The material to be melt spun may be in the form of a powder. The material may be polypropylene in granular form.

Title: Growing multilayer semiconductor crystals
IPC: H01L29/00
Filed: 1971-04-08
Abstract: 1332942 Semi-conductor devices WESTERN ELECTRIC CO Inc 19 April 1971 [14 April 1970] 26731/71 Heading H1K First, second and third epitaxial layers are grown on a seed of a III-V compound material by successively applying a first solution comprising a first and a second group III element in which the III-V compound is dissolved, a second solution comprising the first group III element in the III-V compound is dissolved, and a third solution comprising the first and second group III elements in which the III-V compound is dissolved, the first and third epitaxial layers having wide band gaps and the second epitaxial layer having narrow band gaps. If the second solution also contains the second group III element it must be in a smaller concentration than in the first and third solutions. As shown, Fig. 1A, a seed crystal 19 of GaAs is mounted in a boat 14 within which is placed a solution holder 15 having recesses 16a, 16b, 16c containing solutions I, II and III respectively. The boat is provided with stops (25), 26 at opposite corners so that by appropriate tipping at predetermined temperatures in a cooling cycle each solution in turn is brought over the seed crystal. The floor of the boat 14 is provided with grooves 18 which remove scum from the solutions when the holder is moved relative to the boat. The furnace is supported by a cradle 22 which has a viewing port 23 located above the seed crystal and this provides a temperature gradient in the solution such that the free surface is cooler than the surface from which the epitaxial layer is grown. This ensures that the solution precipitates to a greater degree on floating nuclei at the free surface to enable very thin layers to be grown on the seed. A thermocouple 21 is used to measure the temperature of the seed. Solution I comprises an excess of GaAs dissolved in Ga and Al and doped with Sn, Si, Te, the deposited layer being of N type having a wide band gap. Solution II comprises an excess of GaAs dissolved in Ga and doped with Si or Si and Zn preferably compensated, the deposited layer being of P-type GaAs having a narrow band gap. Solution III comprises an excess of GaAs dissolved in Ga and Al and doped with Zn, the deposited layer being of P-type Ga 1-y Al y As having a wide band gap. The resultant device may be utilized as a junction laser or as an optical waveguide. In an alternative apparatus, Fig. 3 (not shown), the solution holder has provision for four solutions and is moved over the seed crystal by means of a push rod. The viewing port is omitted and the temperature gradient in the solutions is obtained by an auxiliary heater positioned below the crystal support. The apparatus may be subjected to mechanical vibration during deposition. The fourth solution is utilized to deposit a layer of GaAs doped with Zn or Ge to facilitate the provision of ohmic contacts which may be produced by evaporation of Cr and Au. The resulting slices may be cut and cleaved to produce laser diodes. (From GB1332942 A) [FR2086052A1]

Title: Expression of polypeptide genes
IPC: C12R1/19
Filed: 1978-11-06
Abstract: Specific polypeptides are prepared by expression of a heterologous gene coding for them in a recombinant microbial cloning vehicle. The gene is arraged to be in reading phase with a DNA sequence coding for another polypeptide so that when the DNA is expressed a precursor protein is produced comprising both the desired polypeptide and the additional polypeptide, there being a cleavage site between them where the precursor protein may subsequently be cleaved. Plasmids or cloning vehicles containing this type of DNA sequence may be used to transform bacterial cultures in particular to enable the bacteria to produce an immunogenic substance comprising a polyeptide hapten, the DNA sequence coding for the hapten and an additional protein sufficient in size to confer immunogenicity on the product of expression and enable antibodies to be raised to it. Alternatively, the bacteria may be enabled to produce a desired polypeptide product e.g. somatostatin linked to additional protein from which the desired product may be cleaved.
