Abstract: A die and process of reinforcing a resin with fibers. The die includes a first mold and a second mold positioned with respect to the first mold to define a passageway having an entrance portion, an exit portion, and a mixing chamber situated between the entrance portion and the exit portion. The first mold has a recess and the second mold has a protrusion which extends into the recess of the first mold to angle a portion of the passageway between the entrance portion and the mixing chamber.

Abstract: Apparatus in which glue is applied to an endless thread by running the thread successively through the bore of a nozzle needle and a nozzle aperture and, when the nozzle needle is retracted from a valve seat, coating the thread with glue which has been forced out of a surrounding chamber. The thread, together with this coating, passes through the nozzle bore. As soon as the nozzle needle is advanced up against the valve seat in the nozzle element, the glue feed ceases and coating ends, so that the thread takes with it at most only very small quantities of glue remaining in the nozzle bore and an exact cutoff of the glue coating is obtained. When the glue is injected around the thread, that is, when the glue is brought together with the thread under a specific pressure exerted on all sides, it is possible to obtain a substantially uniform coating of the thread surface with glue which allows all improved bonding of the thread over its length to the sheet-like structure.

Abstract: Concrete elements, such as blocks or bricks, are molded or cast by forming in a primary mold cavity a secondary mold made of a portion of a thermoplastic film which has been contacted with a flat heater surface to assure a uniformly heated film portion which is then sucked into the primary mold cavity without wrinkles and filled with concrete mix. The secondary mold with the concrete mix in it is withdrawn, for example, sucked out of the primary mold cavity well before any effective hardening of the concrete mix, so that curing and hardening takes place in the secondary mold outside the primary mold cavity. This early withdrawing is important because it avoids expansion of the curing mix in the primary mold, whereby removal from the primary mold is facilitated. Additionally, the early removal with the aid of the secondary mold assures a more efficient use of the primary molds which are used again while the hardening is still going on in the secondary mold.
