IPC: B01F7/16
Filed: 1975-03-25
Abstract: 1480021 Bubble dispersing apparatus MITSUI MINING & SMELTING CO Ltd 25 March 1975 [25 March 1974 (2)] 12388/75 Headings B1C and B2H A bubble dispersing apparatus, e.g, for separating solids from a fluid, comprises a tank 1 for containing a liquid or a mixture of liquid and solids, a vertical rotary shaft 8 in said tank and connected to a power source, a fixing plate 14 fixed to the lower part of the shaft perpendicular thereto, stirring blades 9 on the lower face of the fixing plate, a plurality of stationary guide blades 6 radially disposed at substantially the same horizontal level and surrounding the stirring blades 9, and a gas supply pipe 15 leading into the tank beneath and coaxial with the centre of rotation of the shaft 8. In operation a gas is fed in through the pipe 15 and collides with the rotating stirring blades 9 and is divided into bubbles as it is thrown out radially. At the intersection between the rotating stirring blades 9 and the stationary guide blades 6 the bubbles are divided into smaller ones by shearing forces, and the bubbles emerge radially from the guide blades and rise in an ascending zone A and are adsorbed onto the surfaces of specific solids to float them to the surface and so separate them from the liquid and other solids. The stationary guide blades are supported from a stand pipe 5 which is sealed off by a member 10 to prevent the escape of gas. In an alternative embodiment (Figs. 5-10, not shown) the apparatus also includes a solidsdispersing device which comprises a similar arrangement of rotating stirring blades (33) and stationary guide blades (32) mounted immediately above the bubble dispersing blades and guides, and a common rotating shaft. Solids are supplied through a pipe (34) onto the top surface of a rotating plate (36) which carries the stirring blades (33). The circulation in the tank caused by the bubble dispersion is confined to the bottom (Arrows C), leaving the rest of the liquid undisturbed except for the ascending bubbles.

Title: Continuous wire feed to processing station - joins end from first bobbin to start from next
IPC: B65H54/10
Filed: 1976-03-23
Abstract: The system is for virtually torsionless wire, which is unwound from a first bobbin continuously, it having been wound on it with opposite torsion, and fed to the processing station, the bobbin being held still so as to make the wire torsionless. A second bobbin is wound with opposite torsion, and the end of the wire from the first one is joined to the start of that of the second one. Thus the wire is unwound from the second bobbin and fed to the processing station whenever the first one is empty, and there is no interruption in the feed. The wire ends can be joined to each other while the first one is being unwound.

Title: Swirl insert for smoke flue of heating boiler - comprises several annular plates mounted one behind other to increase heat transfer
IPC: F24H9/00
Filed: 1976-09-08
Abstract: The insert for increasing turbulence of flue gas in the smoke flue of a heating boiler, which is surrounded by a heating medium, consists of at least one annular plate perpendicular to the axis of the smoke flue. The plate's outer edges are applied to the inner wall of the smoke flue. There may be several annular plates mounted one behind the other with a distance between them sufficient to form a flow plane of max. continuity on the inner wall of the smoke flue; the plates may be mounted on rods of a U-shaped frame. The arrangement prevents formation of a laminar barrier layer over the total heating surface, thus increasing heat transfer, and leaves the cross-section of the heating pipe free to reduce pressure losses to a min. by allowing unobstructed flow at the centre where the flue gas flow rate is highest according to parabolic speed distribution.
Patent FR-2366093-A1 (FR)
Title: Lead-tin alloy soldering rods produced by casting - having dendritic structure refined by hammering
IPC: B23K35/40
Filed: 1976-10-04
Abstract: Soldering rods produced from lead/tin alloys by casting in a mould are subjected to mechanical shock by sharp hammering to produce a breaking up of the needle like dendrites of prim. crystallisation resulting from the casting. This hammering produces a sudden tension in the rod to cause the rod to elongate. The rods may be used in conventional processes such as plumbing, galvanising and car-body mfr. Because the dendrites are less coarse than those found in conventional cast rods, the rods are easier to work as when fused they remain fluid longer. While the coarse dendritic structure can be alleviated by wire-drawing the invented technique is cheaper.
Patent FR-2370813-A1 (FR)
Title: Appts. for manual prodn. of rugs - with tufts of knotted yarn e.g. wool
IPC: D04G3/02
Filed: 1976-11-10
Abstract: The deive is used for making rubs by hand, by forming knots rapidly, using e.g. a woollen yarn, in a base fabric. It comprises a long body with a front end for holding a U-shaped guide whose prongs are fitted into the body. The guide is bent radially inwards in relation to the lengthwise direction of the body. The body has a slot in its front end. The width of the slot is narrower than the distance between the prongs of the guide. Two tufts of yarn may be taken up by the slot and held in place by friction. A sliding element is fitted in the long body of the device, which may move against the action of a return means from a back rest position to a front position. The element terminates in a fork opening into the slot. In the front position, the element penetrates between the prongs of the guide. Arrangement is intened to improve upon the conventional rug hook provided with a pivoted latch, which on withdrawal of the hook, forms a kind of needle eye to knot the yarn. The rug hook requires both hands to work it, the sustained attention of the user, and there may be a lack of control over the tightening of the knots. Such disadvantages are now eliminated.
