Title: Closure system
Inventor: VAN DEN BRINK ANTHONIE
IPC: B29C45/28
Filed: 1982-02-17
Granted: 1984-09-06
Abstract: Known apparatuses to inject liquids, in particular plastics into injection moulds have closure rods which remain in the gating when the closure system is opened. In the present apparatus the liquid passage always is completely free when the closure system is opened, because the closure rod can be totally retracted from the liquid passage. This can be accomplished in two ways: either the liquid passage extends in a bended manner or the closure rod has a side view in the configuration of a sector or a circle.

Title: Process and device for the production and direct application of ready-to-use building material preparations
Inventor: SCHONHAUSEN HORST DR
IPC: E04G21/04
Filed: 1984-03-20
Granted: 1989-03-16
Abstract: A process for the preparation and immediate use in situ of ready to use blends of structural material, such as plaster, mortar, stucco, tile adhesive or similar blends, which, in contrast to the usual methods does not use as a raw material a dry mixture of the three main components binder, filler and additives. Instead a dry mix of binder and filler is prepared at the building site, and an aqueous solution of the additives is added in a separate mixing operation, immediately followed by the application in situ of the finished blend. This method avoids the difficulties associated with the use of dry mixtures containing all three components. The invention includes an apparatus for mixing and immediate application of the blends as defined by the process claims. In an especially advantageous form of the invention, part of the aqueous solution of additives is added to the rest of the blend, after mixing and preferably at a point situated between the conveyor pump and the transport hose, in the form of a cylindrical thin concentric mantle surrounding a core of the wet blend. Much of the friction between the structural blend and the transport conduit can thus be avoided, as well as the wear associated with it. The application of the structural blend can be assisted by pressurized air injected into the stream upstream of the applicator nozzle. The stream of air may be loaded with airborne particles of silicone solution in order to impart water repellency to the structural layers made by the process.
