Abstract: 982,714. Melt spinning synthetic filaments. BRITISH NYLON SPINNERS Ltd. Sept. 19, 1963 [Oct. 12, 1962], No. 38709/62. Addition to 901,398. Heading B5B. The apparatus of the parent Specification (wherein an apparatus for melt-spinning a synthetic linear polymer comprising a metering pump for forwarding molten polymer to and through a filter and thence through an orifice or orifices in a spinneret plate, a filter and a spinneret plate is provided with means for continuously supplying an inert gas to the vicinity of the face of the spinneret plate) is modified in that the means comprise a number of holes equispaced around the outside of a pack containing the filter and spinneret assembly, said holes leading from the upper part of a recess in a metal block forming part of the spinning head or unit, into which recess said pack is fitted and leading into a space of annular cross-section which surrounds both the lower part of the pack and the spinneret and terminates at its lower end in an annular slot or mouth leading into a shallow zone adjacent to the face of the spinneret plate. As shown in Figs. 1 and 2, a steam supply pipe 1 is drilled through the metal-block 3 of a melt spinning unit and discharges into a recess 5 in which is fitted a pack 7 containing a filter and spinneret assembly. At the discharge end of pipe 1 is fitted a plug 11 having passing through it a metering orifice 13. The pack 7 is forced into operating position within the port 5 by screwing pack nut 15 into the metal block 3. The shoulder of the pack nut 15 bears against a complementarily shaped flange 17 of the pack easing. Just above the area of contact, a number of equi-spaced holes 19 are drilled through flange 17, through which holes the steam passes uniformly from the upper part of the recess 5 into the space 21 of annular cross-section surrounding the lower part of the pack 7. This annular space broadens out at its mouth, opening into the shallow zone adjacent the face of the spinneret plate 9, and its walls are directed inwardly near the mouth towards the centre of the spinneret plate. The shoulder of pack 7 is chamfered to allow for easy passage of steam around the upper portion of the pack. The modification of the parent Specification enables a uniform supply of steam to be obtained even if a diffusor ring is omitted and whether the steam is at atmospheric pressure or at a higher pressure when approaching the vicinity of the face of the spinneret plate.

Abstract: 840,303. Typewriters &c. OLIVETTI & C. S.p.A. ING. C. Dec. 2, 1958 [Dec. 5, 1957], No. 38788/58. Class 100(4) A justifying mechanism has manually settable means for adding to or subtracting from the escapement movement by rotating the escapement mechanism support. A carriage rack 5 is held by a pinion 9, secured to a wheel 10, Fig. 3, controlled by escapement dogs 18, 19 pivotally mounted on a support 15 rotatably mounted on a common axis with the pinion and wheel 9, 10 on a hub 11 rotatably mounted in the machine frame. Depression of a key or the space bar acts through a lever 34 to rock a lever 30 clockwise its roller 31 disengaging the dog 18 from the wheel 10 and through a link 28 engaging a pawl 19 thus allowing the first part of the escapement movement. Release of the key or bar allows springs 22, 26 to restore the lever 30 thus reengaging the pawl 18 and completing the normal escapement movement. The justifying mechanism comprises a rail 46, Fig. 1 pivoted at 48 to a part of a margin stop 7 and urged by a spring 50 into contact with a roller 51 mounted on a pivot 52 held in cross slots 55, 57. To add to or subtract from the spacing of a line a knob 63 is turned which raises or lowers a plate 58 and a bail 54 with the pivot 52 thus tilting the rail 46 so that as the carriage advances a roller 44 urged by a spring 45 to contact and follow the rail 46 turns a sector 42 which engages and turns a pinion 41 secured to the support 15 which is thus turned. For shorter lines movement of the carriage stop 8 moves the slot 55 and the pivot 52 to increase the tilting of the rail 46 and thus the speed at which the pinion 41 is turned during travel of the carriage along one line. Progressive turning of the support 15 alters the initial angular position of the pawl 18 and this angular movement is added to or subtracted from the normal angular movement of the wheel 10 at each escapement movement thus justifying the line. In the zero position of the knob 63 the pinion 41 is locked by a hook 66 which is withdrawn as the knob 63 is turned through linkage 69 to 72. Carriage return silencing. A lever 73 frictionally engages the wheel 10 so that on a carriage return movement it is rotated clockwise, Fig. 3, so that its edge 74 engages the roller 21 to swing and disengage the pawl 18. Carriage releasing. To withdraw the pawl 18 to allow manual movement of the carriage the release lever acts through a lever having a lug 77 which engages an arm 76 of the dog 18 to withdraw it.

Abstract: 1,245,653. Semi-conductor devices. MARCONI CO. Ltd. 16 July, 1969 [14 Aug., 1968], No. 38862/68. Heading H1K. In the manufacture of an integrated circuit containing a photodiode and an associated MOST the surface region 7 of the diode and the source and drain regions 8, 9 of the transistor are produced simultaneously by indiffusion of the same impurity. Though the diode surface region 7 is much shallower, this may be achieved by exposing the source and gate areas directly to the impurity while covering the area of the surface region with an impurity-pervious coating-the rest of the body is masked. The body may be of silicon provided with a silicon oxide masking layer 2 and with a much thinner silicon oxide layer 4 which is pervious to the boron or phosphorus used as the diffusant. After the diffused regions have been formed the oxide in the gate region is replaced by a new thinner layer acting as the gate insulation and the oxide over the diode is thinned to provide an anti-reflection coating. Aluminium contacts are provided.
