摘要： A foam reaction mixt. is produced continuously from at least 2 liq. reagents, the liq. mix being centrifuged whilst it foams and then fed to a processing area. Mix is passed into an already rotating mix but beneath the surface level of the latter. Mix produced is free from occluded air, it can therefore be discharged in small quantities if desired.

摘要： 1475275 Mixing liquids MASCHINENFABRIK HENNECKE GmbH 9 Jan 1976 [16 Jan 1975] 00783/76 Heading B1C Apparatus for mixing (e.g. polyurethane) liquid reaction components comprises for each component a storage container 1, a feed line 9, 10 and a metering pump 3 supplying a pressure controlled injection nozzle 4 and a common mixing chamber 6. There is a recirculation line 11 in which is a pressurizing valve 12 and a shut-off valve 14; the injection nozzle opens when the valve 14 is closed. In operation the valve 12 is set to open at a pressure below that of the injection nozzle valve 8 and above that at which air and other gases in the component will remain in solution. The valves 14 are controlled by timers to proportion the respective components.

摘要： 1423582 Mixing in conduits BAYER AG and MASCHINENFABRIK HENNECKE GmbH 19 Oct 1973 [25 Oct 1972] 48828/73 Heading B1C [Also in Division B5] Moulding apparatus comprises means for introducing reaction components into a mixing chamber 9 (Fig. 1) and a remixing system 13 for homogenising the reaction mixture comprising an arrangement of channels provided with branches 16 and junctions 17, 18 arranged between the mixing chamber 9 and a mould cavity 19, the dividing plane of the mould extending through the mixing chamber 9 and the remixing system 13. The reaction components are supplied from storage containers 1, 2 through injection nozzles 7, 8 by pumps 5, 6. As shown the remixing system &c is formed in one part of the mould, the other part comprising a plane surfaced cover. Alternatively the system may be formed in both parts of the mould. In Fig. 3 (not shown) the remixing system comprises a series of barriers 33 formed in a sprue section 30. Fig. 4 shows a further embodiment comprising two mould parts 37, 38 hinged at 39. The remixing system 46 comprises two sections 50, 51 in the form of replaceable inserts 58, 59. In the section 50, an outlet 45 from a mixing chamber 44 opens into a distributing channel 52 connected by mixing channels 53 to a collecting channel 54. The section 51 comprises a distributing channel 52 connected by mixing channels 56 to a collecting channel 57. When the mould is closed the channels 53, 56 cross over one another. Channels 56 increase in cross section in the direction of flow while channels 53 decrease. In another embodiment the mixing channels have the same cross-sectional area but differ in depth and width over their length.

摘要： 1392859 Moulding foam blocks; laminates MASCHINENFABRIK HENNECKE GmbH 10 May 1972 [11 May 1971 31 Dec 1971 (2)] 21954/72 Headings B5A and B5N In a process for the continuous production of a block of foam plastics, a liquid foamable mixture, e.g. polyurethane, is supplied to a lower cover layer 3, Fig. 1, carried on a laterally bounded travelling support 2 and, before a skin can form on the upper surface of the foaming mixture, an upper cover layer 12 and a levelling device 16 are brought in contact with the said surface to float thereon thereby transversely levelling the foaming mixture. The upper cover layer may be a foil or a sprayed-on liquid film, a gas-permeable layer and/or a liquid impermeable layer. The levelling device may comprise a flexible mesh or web of wire, plastics or rubber or a slatted grating, Fig. 3, comprising two separable parts 19, 21, 23 and 20, 22, 24. The lower run of an endless belt may rest on the top of the foaming mixture to form the levelling device. A cleaning arrangement, e.g. a solvent-spraying device and/or a stripper may be associated with the levelling device.

摘要： Continuous rectangular block of plastic foam are produced by a free foaming process in which the plastic mixture is fed on to a laterally enclosed conveyor belt and its movement and expansion aided and controlled. The surfaces of the two enclosing sides and of the conveyor belt are covered by moving foils unwinding from rolls, whilst the plastic material itself may be covered by a gas-permeable sheet and a further covering to impede the escape of fluids, both of which wind off from assemblies supported over the foaming area. On the covers there is a levelling device comprising a roller and heavy metal grill. This mechanism is supported in a conveyor and is adjustable horizontally and vertically.
