Title: Process for dyeing wound packages
IPC: D06P3/66
Filed: 1962-02-10
Abstract: Fibres or filaments of natural or regenerated cellulose are dyed with reactive dye by a process which comprises mounting rounf packages of the cellulosic fibres or filaments on a hollow perforated tube which forms the axis of a centrifuge, pumping the alkaline solution of a reactive dye through the hollow axis into the package and then hydro-extracting the package and fixing the dyeing. The dye solution may also contain a melting agent which is preferably low-foaming, e.g. a mixture of an organic solvent and an anionic compound such as an aliphatic sulphonic acid, as well as a neutral salt such as sodium chloride or sodium sulphate, to assist the fixation yield. The specified alkalis are sodium hydroxide, sodium carbonate, trisodium phosphate and their potassium analogues. An anti-foam agent, e.g. of the silicone type, may also be included. The apparatus consists of a centrifuge hand which supports the package, the centrifuge housing, the driving mechanism and a feed tank equipped with a circulatory pump. At the centre is fitted a perforated conical tube upon which the package is mounted. From the bottom of the centrifuge mounting, which remains stationary, the excess liquor is drained off and recirculated. The rotating speed of the centrifuge is 1000-6000 r.p.m. i.e. 1000-2500 r.p.m. for impregnation and 2500-5000 r.p.m. for hydroextraction. For operation, either the dye liquor may be pumped upward through the hollow axis, with or without pressure, by means of a rotating packing ring fitted between the motor and the centrifuge head in which case the total impregnating and hydro-extracting time is preferably 40-90 seconds, or impregnation is carried out while the package is stationary by pumping the liquor through a flexible tube into the perforated conical tube from the top downward and under pressure, e.g. 1 atmosphere, until the liquor runs out evenly on the outside of the package then the tube is detached and the package is hydro-extracted for 20-60 seconds. In the latter case the rotating packing ring between the motor and the centrifuge head may be omitted. Fixation may be achieved by leaving the packages in the moist state for 3-48 hours or by steaming at 100-105 DEG C. Examples of dyeing cotton, linen and viscose staple are given in which many reactive dyestuffs are specified. Specifications 751,244 and 904,581 are referred to.

Title: Sealing method and apparatus therefor
IPC: B65B53/02
Filed: 1963-11-20
Abstract: The gathered end of a bag of heat-shrinkable material is sealed by first heating it, without applying appreciable pressure, and then cooling the heated mass while applying sealing pressure. In the machine illustrated, the neck of a filled bag is gathered by clamps 52, 53 (Fig. 1) drawn together by light springs and carried by an endless conveyer 48. Flanges 66, 67 (Fig. 5) on the clamps are then carried into heating bars 79, 80 (Fig. 1), and subsequently through converging bars 81, 82 which cool the gathered neck and apply pressure to seal it. The pressure should be sufficient to reduce the thickness of the neck at least 10%. The clamps may print or emboss the bag neck. The bars 81, 82 may be continuous with the bars 79, 80, or guiding rollers 34, 35, or a funnel-shaped guide, may assist in directing the gathered bag neck into the cooling bars 81, 82. The gathered neck may be trimmed at 101 before it is heated. The bag is preferably evacuated, before the neck is heated, by a suction nozzle which moves with the bag and is withdrawn immediately before the trimmer 101. The bags are subsequently carried through a heat-shrinking oven.

Title: Monolithic semiconductor microcircuits with improved means for connecting points of common potential
IPC: H01L27/04
Filed: 1967-06-28
Abstract: In a monolithic integrated circuit comprising a body of semi-conductor material having a relatively low conductivity substrate of one conductivity type surmounted by a layer of the opposite conductivity type containing at least some of the circuit components, connection of various component electrodes to a common potential is achieved by providing a relatively high conductivity layer of semi-conductor material of the first conductivity type on the lower face of the substrate and electrically conductive means extending through the substrate and the opposite type layer. The electrically conductive means may comprise the isolating regions surrounding the components. As shown, Fig. 2, a relatively low conductivity P-type silicon substrate 18 is provided with a P + type layer 16 and an N type layer 20 by epitaxial deposition. Circuit components, such as the bipolar transistor 22 and the resistor 31 are formed by appropriate diffusions into the N type layer 20 and are isolated by P + type regions 36, 38 diffused completely through the N type layer 20 and the P type substrate 18. The emitter region 26 of the transistor and one end of the resistive region 32 are connected to ground by conductive tracks 44, 50 which terminate in contact with the isolation regions 36, 38 which, together with region 14, form conductive paths to a metal ground plane 12 on which the wafer is mounted. N+ type regions 30, 34 may be provided beneath the transistor and the resistor by diffusing impurities into the substrate 18 before epitaxially depositing layer 20. These N+ type regions decrease the collector saturation resistance of the transistor and prevent parasitic transistor actions. Tracks 44, 50 and other connections (not shown) to the base and collector regions of the transistor and to the second end of the resistor, extend over a silicon dioxide layer 40 provided on the surface of layer 20. It is mentioned that integrated circuits may contain other components such as unipolar transistors and capacitors. Resistors and capacitors may also be fabricated partially or completely on top of the insulating layer.
