Abstract: 1375409 Extruding tubes R. HAGEN [trading as KAUTEX-WERK REINOLD HAGEN] 30 Dec 1971 [4 Jan 1971] 60715/71 Heading B5A A multilayer thermoplastics tube is extruded from a cross-head die 113 in which a melt entering an inlet 120 is divided at 122 into two streams flowing first in opposite directions around a mandrel 114 and then along and progressively around the mandrel on opposite surfaces of a sleeve 119 until the opposite edges of each stream meet to form two separate tubular streams having circumferentially offset longitudinal seams, the tubular streams being united in an annular chamber 116 leading to extrusion orifice 117. Alternatively the two streams may be further divided into two component streams which are re-united to form tubular streams each having two diametrically opposed weld lines offset 90 degrees to the weld lines of the other stream. A storage chamber 145 contains an annular piston 146 connected by rods 147 to a ring piston 148 in chamber 149. The pressure of the melt is used to force piston 146 back until chamber 145 is filled, whereupon fluid is forced into cylinder 149 causing piston 146 to move forward and extrude the contents of chamber 145 through the orifice 117, thus parisons for blow moulding are discontinuously extruded while continuously operating the screw of the extruder 111. There may be two inlets and associated duct systems to provide a hollow body having inner corrosion resistant layers and outer layers of greater mechanical strength.

Title: Reducing the effect of defective elements in a thermal image detector array
IPC: H04N3/09
Filed: 1978-12-19
Abstract: In thermal imaging systems in which a line array of thermal radiation detectors 3 is scanned transversely to its length relative to an image of a thermal scene to produce a visible reconstruction of the thermal scene having as many picture lines as detectors in the array, the variations of detector gain and noise along the array 3 and failures of detectors produce "liney" pictures and absent lines respectively. To reduce these effects a scanning cycle is used in which, between scans, the thermal image 17 is displaced along the array by a multiple of the detector pitch. In a group of such scans 18, 19, 20, 21, each line in the picture is scanned in turn by several different detectors. The visible image is reconstructed by methods which average the signals of the different detectors for each line, for example by persistence of vision, reducing the degrading effect on the picture which any one detector can have by virtue of excess noise or zero signal. <IMAGE>

Title: Method and apparatus for making optical glass articles
IPC: G02B6/00
Filed: 1979-06-05
Abstract: A glass optical waveguide filament preform is prepared by chemical reaction of vapor ingredients within a glass substrate tube. As the reactants flow through the substrate tube 52, a hot zone 54 traverses the tube to cause the deposition of sooty reaction products 44' in the region of the hot zone, the soot being consolidated to glass layer 48'. A baffle tube 50 extends into that end of the substrate tube into which the reactants flow. The baffle tube 50, which traverses the substrate tube along with the burner 56, ends just short of the hot zone 54 so that no soot is deposited thereon. A gas flowing from the baffle tube creates a gaseous body or mandrel 66 which confines the flow of reactant vapors to an annular channel adjacent the substrate tube wall 52 in the hot zone, thereby increasing deposition rate and efficiency. <IMAGE>

Abstract: An interferometer type measuring system determines the position of a body simultaneously in three co-ordinates. A laser beam is split (at 2) into three parallel beams and each is fed to an interferometer beam splitter (4) forming respective measurement and reference beams. The measurement beams each pass through a respective refracting wedge (8) deflecting the beam a predetermined angle from the axis of the interferometer. The three wedges are oriented at angular intervals about the axis to deflect their beams in different planes. Each measurement beam is reflected back on itself by a triple reflector (9) fixed to the body under test and again reflected back along the complete double path by a plane reflector (11) behind the wedge (8) and fixed relative to the beam splitter (4). The superimposed measurement and reference beams are each monitored by respective photoelectric devices (12) and the output signals of the devices (12) are fed to a processor (13) to calculate the positional changes of the body and reflector (9) in the three reference co- ordinates. The subtractions between the analogue output signals are performed before digitisation. <IMAGE>
