Title: Photo-oxidation process and porphyrins for use therein
IPC: C11D3/00
Filed: 1958-11-13
Abstract: A process for the production of an oxidation product of a photo-oxidisable organic compound comprises exposing said compound to light in the presence of molecular oxygen and of a porphyrin or of a metal salt of such porphyrin, said porphyrin having at least one aromatic or heterocyclic group present in a meso-position of the porphin ring or having at least one aromatic group connected to one of the pyrrole nuclei participating in the porphin ring; this aromatic group may be a substituent in the pyrrole ring or fused thereto.  When all the available positions on all four pyrrole rings are substituted by aromatic groups or when all four pyrrole rings have aromatic rings fused thereto, one or more of the meso groups may be replaced by a nitrogen atom, i.e. aza- and polyaza-porphyrins. Metals specified for forming the porphyrin salts (chelates) are alkali and alkaline earth metals, zinc, magnesium, copper, iron, nickel, cobalt, silver, aluminium, chromium and lead.  The amount of porphyrin used as catalyst may be from 0.0001% to 1% or more by weight of substrate.  A solvent may be present (organic or water) but is usually absent. Temperatures of 20 DEG C.-30 DEG C. are preferred. The oxygen may be diluted, e.g. as air.  Light of wavelengths between 3600 and 8000 Angstrom units is preferred.  Suitable substrates include: mono- and polyolefines (acyclic and cyclic), including olefinic acids and aldehydes and dienes of the sterol series such as ergosterol, which give hydroperoxidic compounds or, in the case of conjugated dienes, cyclic peroxides; amines which give amides; thioureas and thiosemicarbazones giving aminoiminosulphinic acids; phenylhydrazones and semicarbazones giving azohydroperoxides; enol ethers giving ether hydroperoxides; and sulphinic acids which give sulphonic acids.  The invention also comprises meso-naphthyl and meso-thienyl porphyrins.  These may be prepared by heating a naphthaldehyde or a thiophenaldehyde with pyrrole in a sealed tube.

Between certain turns of one or more windings of a transformer, a conducting layer 2, of a material of high resistivity or an insulating film which in the frequency range of the partial resonances has a large dielectric loss angle is inserted in order to damp the partial resonances due to inter-turn capacitance. The layer may comprise paper coated with a material of high resistivity e.g. carbon black or a colloidal graphite dispersion or an insulating film coated with vapour phase deposited metal. The selection of the turns and windings having these damping layers is determined by the transformer design and the required frequency of operation, the transformer being intended for use in an amplifier used in the communications field and may have a negative feedback winding. Also it may be of the disc coil type, the damping layers being between the disc coils or between radially spaced layers thereof.

Title: Production of catalysts particularly suitable for hydrogenation treatments
IPC: B01J27/051
Filed: 1934-12-27
Abstract: Catalysts comprising sulphides of molybdenum or tungsten are prepared by treating initial material containing molybdenum or tungsten in a dry process with volatile oxygen-free sulphur compounds, particularly hydrogen sulphide, with an addition of ammonia and preferably under pressure.  The treatment may be performed either so as to yield sulphides or only so far as to produce the thio salt, which may be converted into sulphide in known manner.  The invention may be used to regenerate spent catalysts, which are treated either alone or in admixture with thio salts or other materials containing molybdenum or tungsten. Carriers may be added and the product may be brought into any required shape.  The treatment may be effected in liquefied hydrogen sulphide in presence of ammonia in a closed vessel at a temperature of 100 DEG  C. or more, and the ammonia also may be liquefied.  The catalysts are particularly useful for the treatment with hydrogen of carbonaceous materials at temperatures of 200--700 DEG  C. and pressures up to 1000 atmospheres.

Title: Method for selective heat sealing or joining of materials
Inventor: HELLER WILLIAM C JR
IPC: B29C35/08
Filed: 1967-08-15
Abstract: 1,204,506. Seaming non-metallic sheet material; laminating. W. C. HELLER. 15 Aug., 1967 [15 Aug., 1966], No. 37462/67. Headings B5K and B5N. Predetermined interfacial areas of adjacent heat sealable surfaces of a plurality of sheets are joined by applying a susceptor material comprising electrically non-conductive oxide particles to at least one of the sheets at a location within each of the predetermined areas to be joined but spaced from the adjacent surfaces to be sealed and thereafter inducing heat in the susceptor material to raise the temperature of the predetermined areas sufficiently to seal the adjoining surfaces of the sheets within these areas. The invention is applicable to the sealing or laminating of sheets forming bags, carton liners, bag closures, carton overwraps and coated folding cartons.  In one embodiment, Figs. 1 (not shown), and 2, a multi-layered sheet containing susceptor material is prepared by magnetic hysteresis heating by feeding a paperboard ply (32), Fig. 1, and a thermoplastic film (36) with a perforated susceptor material (34), e.g. electrically non-conductive ferromagnetic oxide particles in a polyethylene or nylon carrier, sandwiched therebetween through a coil (41) and then between pressure rolls (33). This material 32a, 34a, 36a, Fig. 6, is fed with a paperboard ply 31 facing the thermoplastic layer 36a through a coil 41a and then between pressure rolls 46. The susceptor 34, 34a and the thermoplastic film 36, 36a need not be provided in continuous layer but may be arranged in an intermittent pattern according to the desired shape of the bond. The embodiment of Figs. 1 and 2 may be modified to be applied to an intermittent, instead of a continuous, process. In another embodiment, Fig. 8, heat sealing is avoided between two layers of a triple-folded assembly of paper-board 71 coated on both sides with polyethylene 73 and accomplished between other layers. The folded layers with a susceptor material 74 positioned at the inner fold are held in place by a coil 76. Pressure is applied at 77. The material 74 may be prepared by milling iron oxide particles into nylon which is not readily heat sealable to polyethylene. After sealing, the material 74 may be removed for re-use. This embodiment is applicable to sealing milk cartons.  In Fig. 9, two plastics films 83 are heat sealed to a wall 82 of a heavier gauge plastics film bag at areas 85 using susceptor layers 87. In Fig. 10, a non-sealing non-susoeptor layer 93 is placed in a fold of a heat sealable material 91. Upon heating the susceptors 87a, heat seals 85a are formed. Instead of using magnetic hysteresis heating, heat may be induced in the susceptor by an ultrasonic energy beam, X-rays, a laser beam, an ion beam, an electron beam or nuclear radiation.
