IPC: C09B47/24
Filed: 1950-11-22
Abstract: Vat dyestuffs are made by treating iron, nickel, or cobalt phthalocyanines insoluble in aqueous alkali metal hydroxide solutions at elevated temperatures and in presence of a diluent liquid at the reaction temperature with phosgene, oxalyl chloride, or sulphuryl chloride under such conditions as to time and temperature that, after saponifying introduced acid chloride groups, the dyestuffs have become vattable in alkaline hyposulphite solution, but remain substantially insoluble in aqueous alkali metal hydroxide solutions. The products contain one carboxylic group to 1-4 mols. phthalocyanine, or one sulpho group to 2-120 mols.  The phthalocyanines may contain non-solubilizing substituents such as methyl, ethyl, propyl, hydroxyethyl, halogen, amino, nitro, and aryl. The products probably contain acid chloride groups which may be saponified in the vat or specially with alkali metal hydroxide solutions.  They dye cotton blue shades from the vat.  Examples describe the above reactions conducted in an aluminium chloride-sodium chloride melt or in trichlorbenzene.  Specifications 496,970 and 510,901 are referred to.

Title: Improvements in or relating to the manufacture of thermo-plastic bags
IPC: B29D22/00
Filed: 1957-09-13
Abstract: 857,521. Seaming. PLASTUS S.A. Sept. 13, 1957 [July 4, 1957], No. 28848/57. Class 42 (1). [Also in Group XVII] In a process of making bags of thermoplastic material, two superposed thermoplastic films 54, Fig. 3, are unwound from a roller 55 and fed between two paper or like support-webs 56 unwound from spools 57, and the assembly is fed by an endless belt 61 between welding electrodes. The belt 61 may be pliable or semihard, and is supported by a fixed plate 62. There are two vertically reciprocating heated electrodes 58 each having an adjustable pointed and projecting element 59, and during the welding operation to form the bags the point of each element 59, due to heat and pressure, severs and then seals the opposed ends of the superposed films 54, and the ledge of the electrode 58 welds the bag edges along a narrow zone. The two paper webs 56 are forced into contact at the points between the bags and they adhere temporarily to the bags. The element 59 may be adjusted so that the films 54 are only partially severed. Instead of two superposed films, a single film folded longitudinally, or a flattened tube of thermoplastic, may be used. The belt 61 may be replaced by a support-roller having a pliable covering, and the pointed element 59 may be arranged centrally of a heated electrode so that welded zones are produced along each side of the severed films 54. The heated electrode may have inserts of silicone rubber arranged on either side of the central projecting portion. The upper paper web 56 may be omitted. The paper webs serve as a temporary support means during the welding and other operations during bag manufacture. In the modification shown in Fig. 6, the lateral surfaces of the heated electrode 5811 form a wedge cam capable of wedging apart two rollers 66 against the action of springs 67. The arrangement is such that when the electrode descends, the rollers are moved apart laterally and downwardly, and co-operate with lower supportrollers 69 to tension the thermoplastic films and paper web supports during the welding operation. In a further modification (Fig. 7, not shown), a fixed support of relatively hard material co-operates with a reciprocable heated electrode of circular cross-section mounted in an insulated recess in carrier member.

Filed: 1973-06-18
Abstract: 1444951 Electroluminescence MULLARD Ltd 18 June 1973 28849/73 Heading C4S [Also in Divisions H1 and G2] A two-terminal image intensifier comprises an electroluminescent layer associated with a semi-conductor layer containing a plurality of isolated discrete regions each forming a potential barrier with the surrounding material and acting as a JUGFET gate to cause local variations in the flow of current through the luminescent layer in accordance with corresponding variations in the charge stored at associated gates. In the Fig. 7 device the semiconductor layer consists of a dispersion in resin of N type ZnO grains and a smaller number of P type ZnTe grains constituting the gates, disposed between tin oxide electrode 42 on glass substrate 41 and a Cu-doped ZnO electroluminescent layer carrying a Schottky contact forming Pt electrode 47. In operation at the start of each frame period a voltage is applied to charge the P type particles so as to block current through the device and interrogation by lower voltage pulses causes current to flow where the gates have been discharged by incident light hv. to cause emission from the ZnO layer. In one modification the semi-conductor layer consists of a deposited stack of N type Si layers with boron-diffused P type inclusions constituting the gates and electroluminescent layer of ZnS carrying a tin oxide electrode. In a variant Fig. 9 (not shown) both electrodes of interdigitated form are disposed on the upper surface of the electroluminescent layer which then has a sufficient lateral resistance to ensure that current between the electrodes has to pass through the granular semi-conductor layer. Dimensions, concentrations and electrode materials are specified and an opaque conductive layer of high lateral resistance may be included to prevent feedback.
