A method for comminuting heat-sensitive feedstock, particularly thermoplastics, rubber, caoutchouc, and elastomers, to a particle size of less than 500 m, preferably less than 425 m. Process steps are provided to achieve an economic material processing without the use of cryogenic comminution. First, a precomminution of the feedstock to a size smaller than 4 mm is performed in a rotating comminuting device through which a first process gas PG.sub.1 flows. Then, a fine grinding is performed of the precomminuted feedstock to a size smaller than 500 m, preferably smaller than 425 m, in a rotating fine grinding device through which a second process gas PG.sub.2 flows. Whereby the temperature of the precomminuted feedstock in the outlet of the fine grinding is regulated in a second control circuit by adding water to the precomminuted feedstock before and/or during and/or after the fine grinding.

A first object of the present invention is to provide a tire puncture sealing agent having excellent sealing property and injectability. A tire puncture sealing agent of a first embodiment of the present invention contains a particular amine compound, glycols, a rubber latex and/or a resin emulsion, and a surfactant. A second object of the present invention is to provide a tire puncture sealing agent having excellent retainability of generated foam and excellent sealing property even in a small liquid amount. A tire puncture sealing agent of a second embodiment of the present invention contains a particular polyether-modified silicone, glycols, a rubber latex and/or a resin emulsion, and a surfactant.

The present invention provides a method for extracting latex from a plant of the Asteraceae family and a method for cultivating a plant of the Asteraceae family, which allow such plants to be reused. The present invention relates to a method for extracting latex including a cutting step of cutting roots of a plant of the Asteraceae family in such a manner that the roots are partly left on the plant.

An extruder is disclosed including: a barrel; and a screw provided with a helical groove; wherein the screw comprises a dewatering portion comprising a first portion, and a second portion at a location downstream from the first portion; wherein, at the dewatering portion, clearance between the groove and the barrel decreases as one proceeds downstream; and wherein clearance reduction ratio at the first portion is greater than clearance reduction ratio at the second portion.

Articles including a polymer film, a plasticizer and a substrate are included. A method of bonding the film to the substrate includes the use of the plasticizer which provides a durable bond by using a lower temperatures and shorter bonding times than would be required in the absence of the plasticizer.

The present invention is a method for manufacturing inflatable articles, or bladders for inflatable articles, that is time-efficient, simple, inexpensive and permits the uninterrupted manufacture of numerous and even customized article or bladder configurations and sizes, without expensive configuration-specific, metal tooling. The method includes the steps of applying a barrier material to a side of a first film, providing a second film with the first film so that the barrier material is disposed between the first and second films, adhering the first film to the second film so that the films are sealed together in areas except where the barrier material has been applied to form at least one inflatable compartment and sealed peripheral edge, and cutting along the sealed peripheral edge to form an inflatable article or bladder for use in an article of manufacture. The barrier material may be a paint, ink, paper or surface treatment that effectively prevents the first film from adhering to the second. The inflatable article or bladder of the present invention may be used as or in athletic equipment, for example, including footwear.

A method of forming the body portion of a three-dimensional object from a polymerizable liquid by the process of continuous liquid interface printing is described. The body portion has a plurality of contiguous segments, and the process includes advancing a carrier for the object away from a build surface while irradiating a build region between the carrier and build surface in a pattern of advancing and irradiating defined by an operating mode. In the present invention, the operating mode is changed at least once during the formation of the body portion for different contiguous segments of the body portion.

A safety barrier for protecting a covered surface from exposure to dangerous fluids is provided with a membrane with a protected region having one or more built-in safety features defined by set of safety related properties and placed over the surface to inhibit the exposure of the dangerous fluids onto or into the surface and a safety indicator providing a visually perceptible alert at the outermost surface of the membrane indicative of at least one safety related property.

A process is described for producing a three dimensional structure, the process including the following steps a) applying of at least a first material M.sub.1 onto a substrate to build a first layer L.sub.1 on the substrate; b) layering of at least one further layer L.sub.y of the first material M.sub.1 or of a further material M.sub.x onto the first layer L.sub.1, wherein the at least one further layer Ly covers the first layer L.sub.1 and/or previous layer L.sub.y1 at least partially to build a precursor of the three dimensional structure; c) curing the precursor to achieve the three dimensional structure; wherein at least one of the materials M.sub.1 or M.sub.x provides a Mooney viscosity of >10 ME at 60 C. and of <200 ME at 100 C. before curing and wherein at least one of the first material Mi or of the further material M.sub.x is a powder. Also, a three dimensional structure is described which is available according to the process according to the invention.
