Abstract: The invention comprises water-soluble reactive dyes of formula <FORM:1009432/C4-C5/1> wherein F is the radical of a dye containing at least one sulphonic acid group, R is hydrogen or alkyl which may be substituted, X is a substituted heterocyclic bridge member of the 1,3-diazine or 1,3,5-triazine series, Y is an anion and n is 1 or 2. The dyes are prepared by condensing 1 mol of a compound of formula <FORM:1009432/C4-C5/2> wherein A is the radical of a dye containing at least one sulphonic acid group or of a compound convertible into such a dye, with at least n mols of asymmetrical dimethylhydrazine and when necessary converting A into a dyestuff radical by azo coupling or condensation.  Specified values of X include halo-pyrimidine and halo-triazine residues further substituted by etherified hydroxy and substituted amino, preferably sulphophenylamino groups.  The dyes may be used to colour natural and synthetic polyamide, polyester, polyacrylonitrile, polyvinyl chloride and acetate, polyethylene and preferably cellulose fibres by the usual reactive dye processes.

In a process for producing methane-rich gases by reacting hydrocarbons having between 3 and 30 C atoms and steam in the presence of a nickel or cobalt catalyst and wherein a mixture of the hydrocarbons and steam is preheated before entering the reactor containing the catalyst to a temperature of not more than 450‹ C. the life of the catalyst is prolonged by passing the product gases through a second reactor containing a nickel or cobalt catalyst after the first decline in activity, the second reactor containing 10-25% of the amount of catalyst in the first reactor, the temperature at which the second reactor operates being gradually increased above the outlet temperature of the first reactor in accordance with the concentration of unreacted hydrocarbon feed in the final gas. The gradual increase in temperature in the second reactor may be obtained by an addition of air to the gases entering therein or by external heating of tubes containing the catalyst. Hydrogen or a hydrogencontaining gas may be added to the hydrocarbon/steam mixture to be reacted.

Powdered material is compacted against an elongated core by rollers to provide a differential thickness in a transverse direction so that any gases may escape owing to the porosity of the thicker sections. Aluminium powder is uniformly distributed around an iron wire 11 by an applicator 13 and is then pressed in the pass formed by the grooves 15 of rollers 16. Each groove 15 presents a curve in cross-section at the pass which is of greater radius of curvature in the centre then the ends so that the covered wire 11a has regions 28 of porosity through which gases escape. The covered rod then passes fine shaver 17 which leaves stubs 27 and a roll guide 18 from which it goes to heating, reduction, and finishing stages.

Abstract: 1428741 Valves LUCIFER SA 3 April 1973 [4 April 1972] 15952/73 Heading F2V A three-way pilot valve for a main valve 1 has an inlet 14 for pressure fluid, an inlet-outlet 16 for controlling the main valve and an exhaust passageway 12. Two magnetic cores 18, 19 sliding in non-magnetic tubular members 8, 10 carry valve members 20, 21 loaded by springs 22, 23. Seats 13, 15, closed by the valve members, are provided on the members 5, 11 closing the tubular members. A ferromagnetic discshaped member 9 joins the two tubular members and has an opening 27 through it. The inlet-outlet passageway 16 leads into an annular groove 17 which connects with a passageway 3 in the main valve. Windings 24, 25 surround the cores 18, 19 respectively. In operation, a current pulse of sufficient duration fed to winding 25 allows pressure fluid to be fed to the passageway 3 to control the main valve and on cessation of the pulse the valve member re-seats to trap the pressure fluid and maintain the main valve in the condition set. A similar pulse fed to the winding 24 releases this pressure to exhaust thus changing the condition of the main valve.

Title: Improvements in or relating to grip-finger assemblies for labelling machines

Filed: 1961-05-03
Abstract: 905,801. Labelling-machines. MEYER MANUFACTURING CO., GEO. J. May 3, 1961 [Jan. 9, 1961], No. 16006/61. Class 73. Relates to a bottle labelling machine for applying elongated labels, e.g. of the form shown in Fig. 9, so that the lower part Y of the label adheres to the upper part of the bottle body, the middle part S<SP>3</SP> extends vertically along the reverse curvature of the bottle shoulder and the upper part N embraces the neck of the bottle. According to the invention a grip finger assembly is adapted to receive a gum-coated label from a picker (not shown), the assembly comprising a vertically-elongated flexible pressureapplying pad P<SP>1</SP>, Fig. 1, having a label-contacting face, all parts of which normally lie in the same plane to receive a label from the picker, and a pressure-applying pad-deforming roller 77, Fig. 2, which is actuated to roll up the rear side of the pad and make its label contacting face conform to the vertical contour of the portion of the bottle to which the label is to be applied. The transfer of the labels from the picker to the pad P<SP>1</SP> is effected substantially in the manner described in Specification 864,625, the pad holding the labels by suction. The soft rubber pad is mounted in an open-sided carrier Z<SP>2</SP> permitting outward movement of its upper portion which is urged towards the carrier by a coil spring 67 and is normally retained therein by a latch spring 54. The pad carrier Z<SP>2</SP> is mounted on a lever arm 29 pivoted at 28 to a rock arm M fixed to a rock-shaft K operated as described in Specification 864,625. A pad-actuating lever arm 22 is fixed to the rock arm M and a coiled compression spring 43 tends to swing the arms relatively in opposite directions to an extent defined by stop elements. Pivoted to the lever arm 22 at 72 are two parallel arms 73 urged anti-clockwise by a spring 74 and carrying the roller 77 while arms 82 pivoted at 81 to the lever arm 22 carrying rollers 86, 87 adapted to bear respectively against the lever arm 29 and the bottle T. When the rock-shaft K is operated to swing the arms 22, 29 towards the bottle from the position shown in Fig. 1, roller 87 comes into contact with the bottle, the arms 82 swing downwardly and the lever arm 22 caused to swing towards the arm 29 as shown in Fig. 2. At the same time the roller 77 comes into contact with the pad P<SP>1</SP> and by an upward rolling action first pulls the upper part of the pad from beneath the latch spring 54 and then makes the pad conform to the contour of the bottle as shown so that the label is brought into close contact with the bottle. A label may be applied simultaneously to the other side of the bottle by a similar device or, as shown, the bottle may be steadied by a pad P<SP>2</SP> supported by a lever arm 29a arranged substantially in the same manner as the lever arm 29.
