Title: A process for ground fixation and an asphalt emulsion for use therein
IPC: C08L95/00
Filed: 1943-08-17
Abstract: 573,006. Emulsions for hardening soil. SHELL DEVELOPMENT CO. Aug. 17, 1943, No. 13348. Convention date, Sept. 15, 1942. [Class 1 (i)] [Also in Groups VIII and XXI] An asphalt-in-water emulsion of temporary stability for hardening or fixing soil is made with an alkali metal soap as emulsifier and contains 0.5 to 10 per cent. by weight of an oil-soluble compound having a molecular weight greater than 300 which consists of a cation surfaceactive organic base or a salt thereof. Stabilisers such as casein, blood albumen or gelatine may also be present, with or without formaldehyde. From 0.5 to 2 per cent. of the soap (or its constituent parts) may be used and from 0.5 to 5 per cent. of the stabiliser. The emulsion is injected into the soil under treatment and coagulates therein to give a. surface impermeable to water. Emulsifiers used may be the alkali metal salts of fatty, naphthenic, asphaltic, rosin, or wool fat acids, acids produced by oxidation of paraffin wax, or oil-soluble sulphonic acids of petroleum for example. Cation surface-active bases comprise quaternary ammonium bases, and primary, secondary, and tertiary amines, which may be aliphatic, alicyclic, aromatic or mixed and should contain at least one aliphatic saturated hydrocarbon radicle of at least twelve carbon atoms. They may contain polar substituents such as chlorine, hydroxyl, ethers, esters, sulphide, hydrosulphide, and sulphur, or may comprise compounds in which the quatenary nitrogen atom is replaced by sulphur, phosphorus, arsenic or antimony. Typical of numerous examples are paraffin wax amine, stearyl amine, ethyl stearylamine, methyl ethyl stearylamine, trimethyl cetyl ammonium, phenyl stearyl ammonium, and palmitic ester of ethanolamine. Salts of the bases with inorganic acids may be used but salts with organic acids, such as fatty acids, aromatic carboxylic acids, dicarboxylic acids, sulphonic acids, or alkyl sulphuric acids, are preferred. Tables are given showing the behaviour of emulsions containing 60 per cent. asphalt with or without casein emulsified by a rosin or naphthenic acid soap and containing as coagulant either a wax amine or its hydrochloride or its stearic acid salt, or a C16-18 aliphatic mixed amine or its acetate or stearate. Specification 409,760 is referred to.

Abstract: Apparatus for the treatment of fibrous <PICT:0419075/IV/1> materials particularly artificial silk wound on perforated bobbins by passage of liquids under suction or pressure through the materials, comprises a separate treatment cell for each bobbin with a liquid inlet and outlet at the centre of the base and an overflow outlet above, a tightly fitting cover pressing the bobbin against a rubber base support, the cover consisting of the cell lid and an elastic intermediate piece which is attached to the lid and holds the bobbin under pressure, simultaneously closing a small opening in the top end of the bobbin which is otherwise of closed construction at that end. The opening permits a twisting spindle to be inserted when required. As shown in the Figure, a trough l comprises a plurality of cells each having a liquid inlet or outlet pipe a, outlet pipe d and overflow c.  A bobbin g is placed with its open end on the rubber plate f. Liquid enters through a and the displaced air passes through a small hole at the top of the bobbin.  The lid k with the stopper e is then lowered and the liquid is forced through the thread windings n.  For changing the liquids, the lid is lifted and the liquid inside the bobbin is removed through a.  The new liquid is then introduced through a until it flows from the top of the bobbin.  If the liquids are of different densities, the old liquid is removed through d at the same rate as the new liquid flows through the top of the bobbin. If the liquids are nearly of the same density, the top of the bobbin is closed after the interior has been filled with new liquid.  In either case air is prevented from coming into contact with the thread windings.

Patent GB-429407-A (GB)
Title: Improvements in or relating to a method of coating surfaces with fibrous material and an apparatus for use therewith
IPC: E04F21/12
Filed: 1934-05-08
Abstract: A method of coating surfaces with fibrous material consists in subjecting the material to the suction action of a jet of compressed air, which suction action also acts directly upon a supply of liquid, so that as soon as the fibrous material is drawn up to or adjacent the jet, it comes into intimate contact with a spray of liquid which, together with the fibrous material, is blown on to the surface to be coated.  The liquid may contain an adhesive, or an adhesive, in powder form, may be incorporated with the fibrous material.  The fibrous material, such <PICT:0429407/III/1> <PICT:0429407/III/2> as asbestos, may enter the tube 1 from a container 2, fed through an aperture 9, and consisting of a rotatable drum mounted on a shaft 10. Sandpaper 7 may be secured to the inner surface of the drum to split up the fibrous material, and leather flaps 12 flick lumps or mass of the material back into the drum, so that only fine material enters the tube 1.  Compressed air is supplied to the jet 4, the concentric jet 5 being connected to a supply of liquid, so that the mixture of fibrous material and liquid is discharged from the nozzle 3.  To prevent clogging of the delivery nozzle, a second jet 6 may be supplied with compressed air.  The whole apparatus, together with its power source, may be mounted on a trolley.  According to the Provisional Specification, an adjustable diaphragm may be provided in the tube 1, between the jets 4 and 6, so that air may be blown back into the drum if the tube 1 tends to become choked.

Abstract: 705,352. Bottling. LARRIEU. H. C. June 4, 1952 [Aug. 10, 1951], No. 14087/52. Class 1261 (2) In apparatus for filling bottles or other containers with liquids having a feed conveyer from which the bottles are displaced transversely to stand under a line of filling spouts carried on a filling head and, after being filled, are further displaced transversely on to a discharge conveyer, a control is provided for intermittently operating a hydraulic device having means for raising the filling head clear of the bottles after filling and means for then controlling members which move the next bottles from the feed conveyer to stand under the spouts. Bottles are supplied by a feed conveyer 4 having spaced stops 6 and driven by a motor 2 energized intermittently through a relay 7 responsive to, e.g. the output of a washing machine. When the conveyer stops, a line of bottles is pushed transversely by members 12 so as to stand on spring-biassed supports 9 and to push previously filled bottles from supports 9 on to a continuously running discharge conveyer 10. The filling heads 20 then descend to fill the bottles from tank 19 and the members 12 are retracted, whereupon a further batch of bottles is supplied by conveyer 4. The filling heads are then raised again and a new cycle starts. The tank 19 and the filling heads are carried on a double tube 26, 27 telescoping on a pillar 37 and reciprocated by a cylinder 36 acting on a rod 34 engaging a block 32 to which the tubes 26, 27 are connected by a screw rod 3,1. To accommodate bottles of different height, the rod 31 can be screwed up or down by a worm 29, the motion, being repeated through a worm 39 to a pointer indicating the setting. In operation, filling having just been completed, liquid is drawn from a reservoir 42 by a pump and forced through passages 49, 48, 47 to space 57 to raise the cylinder 36 and, hence, the heads 20. Liquid then passes from space 57 through passages 58, 59, 46, 54, 53 to space 66 to move out cylinder 55 which pivots levers 15, 13 about pivots. 14 to cause members 12, to feed a new batch of bottles and discharge a filled batch. The throw of members 12 cam be adjusted to different bottle diameters by a cam 18. The pump then stops, whereupon cylinder 36 and the filling heads descend by gravity and cylinder 55 is retracted by a spring, displaced liquid flowing from space 66 through passages 53, 54, 46, 63, 60, 61 back to reservoir 42.
