Title: Monoazo dyestuffs of the benzene pyrazolone series and metal complexes thereof
IPC: C09B45/14
Filed: 1956-10-17
Abstract: The invention comprises a dyestuff of formula <FORM:0796918/IV (b)/1> and metal, especially cobalt and chromium, complexes thereof.  The metal free dyestuff is made by coupling diazotized 1-amino-2-phenol-4-sulphonamide in an alkaline medium with 1 - (31 - nitrophenyl) - 3 - methyl - 5 -pyrazolone. Metallization is effected in conventional fashion on the fibre or in substance, in the latter case preferably to yield 1,2-complexes.  Mixed complexes in which one of the dyestuffs is of the above formula and the other of a different metallizable dyestuff may also be formed.  The dyestuffs dye and print animal materials such as wool, silk, leather and synthetic fibres of polyamides or -urethanes.  In an example the dyestuff and its cobalt and chromium complexes are prepared, the metal complexes being used to dye wool in yellow-brown and red shades, respectively. Specifications 637,404 and 758,016 are referred to.

Abstract: 952,447. Valve sawtooth circuits. PYE Ltd. Sept. 12, 1960 [Sept. 18, 1959], No. 31868/59. Heading H3P. In a sawtooth generator of the type in which the charge on a capacitor is controlled by a " bootstrap " cathode follower, negative feed-back is provided between the deflection coil and the cathode of the bootstrap cathode follower. As shown, capacitors C1, C2, C3 are charged via resistors R1, R2 under control of the bootstrap cathode follower V2. Capacitors C1 to C3 are discharged by V1 being rendered conductive by synchronizing pulses at the end of each sweep. The rate of charge is reduced at the beginning and end of each sweep by resistors R3, R4 to provide an S-shaped waveform required by wide-angle flat-screen cathode-ray tubes. The waveform is linearized by feed-back from deflection coil L to the cathode of V2. Amplitude is controlled by R7; R10 provides a centring adjustment. The deflection coil L may alternatively be connected to the anode as at L<SP>1</SP> or via a transformer. The circuit shown is suitable for frame deflection in a television receiver. In a line deflection circuit, R8, R10 may be returned to earth and a blocking capacitor connected in series with R9. Specification 952,448 is referred to.

[Class 39 (i)] In an electron discharge device one or more electrodes are supported by a metal band clamped around a portion of the tube, and means are provided for preventing the band from forming a closed electrical circuit. For example, an insulating bush may be inserted beneath the head of a screw provided for clamping the band on the pinch, or the band may be partly or wholly coated with insulation. The heating of the band by high-frequency currents used for degassing or " gettering " is thus reduced and the possible cracking of the pinch prevented. Bands with more than one insulating section may be necessary, as in the case of an anode having a number of supports which may form closed circuits with portions of the band.

Abstract: 246,116. Sinclair Refining Co., (Assignees of Herthel, E. C., and Pelzer, H. L.). Jan. 17, 1925, [Convention date]. Hydrocarbons, cracking.-Oils, during cracking are circulated through a body of metal oxide other than iron oxide or bauxite to separate substances which tend to form carbon deposits on the heating surfaces. The oxides, for example, copper oxide, may form a layer on a bed of filtering materials such as asbestos, disintegrated sil-o-cel or fire brick, sand, kieselguhr, pumice, glass or mineral wool, ground coke or charcoal, fuller's earth, or other absorbent clays, acid treated clays or silica gel, through which the oil circulates or the oxide may be precipitated on the filtering material. For cracking by circulating oil from a drum 1 by a pump 3 through a tubular heater 5 a layer of metal oxide is supported by a perforated screen 29 across the drum. The heater discharges into the drum by a pipe 6 above the layer. Vapours pass up a reflux tower 15 down which fresh oil supplied by a pipe 27 passes. Oil containing tar, &c. is withdrawn by a pipe 26. Specifications 232,178 and 241,866 are referred to.

[Also in Division B8] A sheet for packaging (see Division B8) comprises an intimate laminate of a supporting film layer, a rupturable film layer and a pressuresensitive layer between the two film layers, the bond formed between the two film layers having a strength greater than that required to tear the rupturable film. A cover 14 for the package comprises the supporting film layer of polyethylene terephthalate resin, nylon, polypropylene or regenerated cellulose 15 and polyethylene 16 having a gas barrier layer of a copolymer of vinylidene chloride and acrylonitrile between them (not shown). The lower surface of the layer 15 is subjected to a corona or electrostatic discharge treatment to increase its wettability and is then coated with a water-based primer of polyethylene imine (not shown). A thin polyethylene film is then applied to the primed surface by a melt extrusion process and a further preformed polyethylene layer is then applied to the extruded layer whilst still molten. The exposed surface of this polyethylene layer 16 also has its wettability increased and the pressure sensitive adhesive layer 17 is then applied. The rupturable layer of polyethylene 18 is applied to the adhesive layer after the polyethylene has had its wettability increased. Polyvinyl chloride may be used for the rupturable layer. A base member 10 for the package which is finally adhered or heat sealed to the cover member at 19 comprises a gas barrier layer (not shown) between a layer of polyvinyl chloride 11 and polyethylene 12. In another form the base member comprises a lower layer of nylon primed with a coating of dibutyl tin dilaurate catalysed prepolymer, a gas barrier layer, a further primer coating and a final upper layer of polyethylene treated to increase its wettability. Adhesive laminated structures can be used instead of extrusion laminates. The surfaces of the cover and base to be sealed together may be made of styrenes, vinyls, propylenes or vinylchloride/vinylidene chloride copolymers.
