Title: A process for bleaching vegetable fibres
IPC: D06L4/70
Filed: 1933-05-02
Abstract: Vegetable fibres, in all stages of manufacture such as loose material, card sliver, yarn, woven or knitted material, are impregnated with a chlorine bleaching liquor and treated with a liquor containing a peroxide without an intermediate bath.  The fibres are preferably pretreated with a wetting agent such as a sulphonated oil and peroxide stabilizers, such as magnesium or other alkaline earth salts of sulphuric acid esters or sulphonic acids of high molecular fatty alcohols, salts of fatty acid alkyl ester-sulphuric acid ester or a mixture of the magnesium salts of a high molecular fatty alcohol sulphuric acid ester and a true sulphonic acid of a fatty alcohol, may also be added.  In examples (1) a knotted tricot is wetted in a bath containing a highly sulphonated castor oil, impregnated with a soda-chlorine bleaching lye and introduced into a bath containing water-glass, caustic soda and aqueous hydrogen peroxide.  The goods, when rinsed, may be treated in a dilute formic acid bath.  (2) An undressed cotton twill is wetted in a bath containing ricinoleic acid-butyl ester-sulphuric acid ester, impregnated with sodium chlorite liquor and introduced into a bath containing water-glass, caustic soda, aqueous hydrogen peroxide and the magnesium salt of sulphonated oleyl alcohol. Chloride of lime solutions may be used in place of the soda bleaching liquors.

Title: Improvements in or relating to oscillating column combustion apparatus
IPC: F23C15/00
Filed: 1957-04-23
Abstract: 810,432. Generating combustion products under pressure. HUBER, L. April 23, 1957 [April 30, 1956], No. 12951/57. Class 51 (1). [Also in Group XXIX] In an oscillating column combustion apparatus which operates with gaseous fuel, separate gaseous fuel and air inlets are provided to the combustion chamber or to a mixing chamber disposed upstream of the combustion chamber, each of the inlets having a return flow check device therein which check devices serve in operation to impress upon the pulsating induction air and gaseous fuel the same phases and amplitude of pulsations. The heating apparatus shown in Fig. 1 comprises a combustion chamber 1 and a resonant exhaust pipe 2 which discharges into an exhaust gas damping chamber 28. From there the gases flow through the heat exchanger 29 into a collecting chamber 30, finally discharging to atmosphere through a duct 31 where they serve to preheat the combustion air flowing through the inlet duct 25. The combustion chamber 1, chambers 28, 30 and the ducts 2, 29 are enclosed within a casing 15 having an inlet and an outlet for the medium such as water, which is to be heated. Combustible gas is supplied through a duct 11 and flows through a valve 12 to a damping chamber 10 and thence through a duct 8 into an antechamber 7 within which is disposed a return flow check in the form of a volute 6 which is connected by a duct 4 to a mixing chamber 3 which in turn is connected to the combustion chamber 1. The valve 12 is opened manually at starting but is subsequently kept open by pressure waves in the combustion chamber 1 acting through the duct 18 and return flow check device 19 upon the diaphragm 16 within the chamber 17. Inflowing combustion air is preheated in the duct 25 and enters the air damping chamber 24 then entering through the inlet 23 into the anti-chamber 22 within which a return flow check device in the form of a volute 21 is disposed. The combustion air then flows through the duct 5 into the mixing chamber 3 and thence into the combustion chamber 1. The air damping chamber 24 encloses the whole of the combustible gas and air inlet apparatus and the mixing chamber 3. The return flow check devices may comprise non-return valves instead of volute devices such a valve being shown in Fig. 3 and comprising a housing 50 and a plate member 56 to which is secured a bolt 55. Apertures 52 are provided in the housing 50 and apertures 69 in the plate 56, an annular diaphragm 59 being disposed between these two parts. The bolt 55 passes through a cap member 63 which is in screwed connection with the housing 50. The end of the bolt is slit at 62 and has an axial threaded bore 61, a split pin 65 passing through a hole in the cap member 63 and through the slit 62 in the bolt 55, a plug 67 screwed into the bore 61 bearing against the pin 65. The width of the gap between the housing 50 and the plate 56 may be varied by rotation of the cap member 63.

Abstract: 833,855. Coating webs. HESSER MASCHINENFABRIK-A.G., F. April 25, 1958 [May 9, 1957], No. 13221/58. Class 140. Apparatus for applying petroleum jelly or other adhesive to wrapping material is characterized by a hollow drum which is open at one side, is rotatable in a reservoir with its casing projecting partly from the latter and is furnished with a set of radial orifices through which adhesive, entering the drum laterally from the reservoir, may be laterally expressed on to the wrapping material passing the drum. As shown in Figs. 1 and 2 (Fig. 2 being a longitudinal section on the line A-A of Fig. 1), a hollow drum 2 is arranged in a housing 1 which forms a reservoir for the adhesive. The drum is furnished with radial orifices 10 and is rigidly secured to shaft 3 and adapted to be driven in the direction of arrow " a " through gearwheel 14. The casing of drum 2 projects partially through slot 4 in the wall of reservoir 1, the lower edge X of the slot forming a central edge for measuring, the quantity of adhesive issuing from orifices 10. Disposed in drum 2, which is open on one side, is cam-piece 5 which bears against the inner surface of the drum casing over its full width and is so shaped as to define with the inner wall of drum 2 a tapered chamber R which is closed at the side by a block 11 bearing against the end of the drum. Cam-piece 5 is rigidly connected to bush 6 which forms a bearing for shaft 3. Cover 8 mounted on hinge 9 is applied under gravity against adhesive V, forcing it through the open side of drum 2 into the latter. When drum 2 is returned in the direction of arrow " a " a back pressure is set up in the tapered chamber R between cam-piece 5, the inner wall of drum 2 and block 11 which forces adhesive out from the interior of the hollow drum through the orifice 10 running past chamber R until this orifice has shifted from central edge X of the housing to control edge Y of the campiece. During subsequent rotation of drum 2 the expelled adhesive contents web of wrapping material B, fed over roller 12, at point P and is thereby expressed thereon and remains adhering thereto.

Patent GB-712684-A (GB)
Title: Process for the treatment of water
IPC: C02F1/00
Filed: 1950-05-30
Abstract: A process for the treatment of hard water to reduce scale formation comprises the production of corrosion by dissolution of graphite or one or more metals, more particllarly iron, zinc or copper, but excluding aluminium, in such a manner that whilst the water remains hard the formation of any passivating film of oxide or metallic salt upon the metallic surfaces, which would stop the corrosion, is prevented, or if such a film is incidentally formed it is immediately removed.  The water to be treated may be caused to pass upwardly inside conical receptacles containing metal shavings and grains of sand or carborundum which by their abrasive action prevent formation of a passivating film in the metal.  The corrosion may be increased by electric current treatment, by radiation from lamps or from radioaction or fluorescent substances, or by formation of galvanic couples by placing the metal to be corroded into contact with more noble metals or by preliminary immersion of the metal in a solution of a more noble metal.  When the water to be treated is non-corrosive or slightly corrosive, corrosive water may be allowed to corrode the metal, the resulting water with corrosive products being then introduced into the water to be treated.  Alternatively such water to be treated may be made more corrosive by addition of an acid or a chloride, by bubbling carbon dioxide through the water, by softening part of the water by zeolite filtering material, by removal of oxygen in solution, or by a hot treatment.  The prevention of the passivating film may be achieved by adjusting the electric potential or resistance of the metallic surface treated, the potential being measured relatively to a reference calomel electrode in the water adjacent to the metallic surface. In the case of iron brought into contact with water at a pH value of 8, the potential should remain below - .55 volts.  Adjustment of the potential or resistance may be done automatically. Specification 25633/11, [Class 46], is referred to.
