Abstract: 1,174,852. Reactive phthalocyanine dyestuffs. CIBA Ltd. 6 July, 1967 [6 July, 1966], No. 31194/67. Heading C4P. The invention comprises phthalocyanine dyestuffs which contain at least one, preferably 2 to 4, sulphonic acid amide group directly linked to the phthalocyanine nucleus, the amide nitrogen atom of which carries a sulphatoalkyl residue, the alkyl group of which may be interrupted by one or more oxygen atoms or tertiary nitrogen atoms and an acylaminomethyl group, the acyl residue of which is fibre reactive. Preferred dyestuffs have the general formula wherein P is a copper phthalocyanine residue, R is an alkylene chain which may be interrupted by one or more oxygen or tertiary nitrogen atoms, X is chloroacetyl, dichloro- or dibromopropionyl, acrylic, chloroacrylic, bromoacrylic, chlorocrotonyl, mono- or dichloro-1,3,5- triazinyl, di- or trichloropyridinyl, chlorobenzthiazolyl-CO- or dichloroquinoxalinyl-CO-, m and n are at least 2 and p is 5 or 6. The dyestuffs are prepared by reacting a phthalocyanine sulphonic acid-N-sulphutoalkylamide, the N atom bearing a hydrogen atom, with an N-methol compound HOCH 2 NHX or a derivative thereof, e.g. where HO is replaced by halogen, alkoxy or acyloxy. The reaction preferably takes place at 15‹ to 80‹ C. in presence of an acid condensing or dehydrating agent. The dyestuffs dye wool, silk, leather, polyamides, polyurethanes and cellulosic materials in turquoise and greenish-blue shades.

Abstract: 1477193 Laminates; adhering extruded layers NATIONAL CAN CORP 18 July 1974 [8 March 1974] 31959/74 Addition to 1399527 Headings B5N and B5A A method of bonding at least two layers of chemically dissimilar sheet material to form a laminated sheet, one of the layers being a plastics film, comprises bringing the layers into contact and subjecting the layers to simultaneous electrical corona discharge treatment continuously from a point prior to contact of the layers to a point subsequently to contact of the layers, the intensity of the electrical corona discharge treatment of the layers being such that the laminated sheet has a peel strength measured on a one inch wide strip of the laminate at 72 F. of at least 200 gms. The intensity of the discharge treatment may be measured by determining the contact angle between a standard liquid and the sheet before and after treatment. The sheet material may be in the form of a sheet, film or foil and may comprise plastics, metal, paper or other fibrous material. The method may be used to bond polyethylene to metal e.g. aluminium foil; a polyolefine film to an acrylonitrile polymer film; a polyolefine film to a nylon-6 film; a polyolefine film to a polyester film or a polyolefine film to a rubberized olefinic nitrile/olefinic ester copolymer film, specified polyolefines being polyethylene, poly. propylene and an ethylene/propylene copolymer and specified polyesters (which may be oriented) being polyethylene terephthalate and polytetramethylene terephthalate. Fig. 5 shows a method wherein three films 10, 11, 12 are drawn over grounded roller 20, discharge being applied between the electrode 18 and the roller over the area shown by lines 19. Fig. 6 (not shown) relates to a similar treatment wherein four films are used. Figs 8, 9 and 10 relate to a method wherein a multi-slit extrusion die is used, Fig. 9 showing the bonding of two extruded films 10 and 11 and Fig. 10 showing the bonding of an extruded film 11 to a preformed film 10, preheated by preheater 14. In the embodiment shown in Fig. 11, two coaxial tubular films 118 and 120 are extruded through circular extrusion slits 92 and 94 of extrusion die 90, the films being bonded at a cooling mandrel 104 which is earthed and encircled by ring electrode 18b.

Class 7(2) A wobbler 5 on an inclined crank pin 2 is spherical and coacts with the crank arms 3 and a crankcase 4 to leave minimum clearance and facilitate crankcase compression. Working pistons 10 having connecting links 8 to the wobbler 5, by virtue of their elliptical motion control transfer ports 16, in them and in the cylinders 9, more by transverse than by axial motion, the timing of the ports being preset by circumferential adjustment of the cylinders 9. Cylinder exhaust and crankcase inlet ports 14, 13 are provided. The wobbler 5 is in halves held together by bolts 6 and has a central hollow or lubricating ducts (not shown) for the link pivots and fed from crankshaft ducts 11, 12. In the construction shown, each link 8 remains on one side of its cylinder axis, giving one power stroke per crankshaft revolution; the construction may be modified so that each link 8 swings across its cylinder axis at T.D.C., giving two power strokes per crankshaft revolution. There may be four cylinders, and two or more complete units as described may have a common crankshaft. Crankcase compression may be regulated by varying the spring loading of a diaphragm in a chamber connected to the crankcase. Specifications 559,737 and 560,733 are referred to.

In a method of detecting flame failure in fuel burners, material is periodically injected into the burner fuel supply to produce a succession of light pulses of distinctive colour and of sufficient intensity to pass through a sooted-up observation window, and be detected by photoelectric means after passing through a filter, the absence of one or more consecutive light pulses causing an alarm to operate and the fuel supply to be cut-off after a suitable time interval. The material may be a barium or coppersalt dissolved or dispersed in oil and producing a green flame. Several flames may be monitored by a single photo-electric means, the flames being coloured consecutively.
