    Abstract: In an example of a three-dimensional (3D) printing method, a build material (consisting of an inorganic particle and a polymer attached thereto) is applied. The polymer is a continuous coating having a thickness from about 3 nm to about 1500 nm, or nano-beads having an average diameter from about 3 nm to about 1500 nm. The build material is heated to a temperature from about 5°C to about 50°C below the polymer's melting point. A coalescent dispersion (including a coalescent agent and inorganic nanoparticles) is selectively applied on a portion of the build material, and the applied build material and coalescent dispersion are exposed to electromagnetic radiation. The coalescent dispersion absorbs the electromagnetic radiation and heats up the portion of the build material in contact therewith to fuse the portion of the build material in contact with the coalescent dispersion and to form a layer of a 3D object.

    Abstract: A method of producing resin articles from a resin reaction system including an uncured resin material and added radiation activatable matter therein. In one case said matter is microencapsulated catayst and, upon application of ultrasonic energy the catalyst is released to initiate cure of the resin. The catalyst is one which is water insoluble and encapsulated with gelatin. In another case, radiation reactive particles such as iron oxide particles are incorporated in the resin and are caused to heat by application of an alternating magnetic field to cure the resin. The field is generated by annular electromagnetic means (14X) borne by a core member (10X) drawn by a cable (12X) through the pipe (1X) and tube (2X). The process is particularly well suited to a replacement pipe and method of installing the replacement pipe within an existing conduit with the resin being cured by passing appropriate radiation generator through a fluid inside the inflated replacement pipe. The invention is of particular interest in mending leaky sewer pipes and the like as the presence of flowing liquid or the like does not affect the radiation.

    Inventor: SOUND PIPE LTD.

    Abstract: The invention provides that flexible lining tubes for application to underground pipelines and passageways comprise absorbent material which is impregnated with curable synthetic resin which can be cured when the tube is placed on the pipeline or passageway surface so that a rigid pipe within a pipe is formed. The curing of the resin is controlled by filling the curing agent into micropores or microporous particles which are dispersed throughout the resin. The curing agent is only released when the resin is subjected to applied energy such as sonic and/or heat energy. A preferred method is to include CURIE temperature magnetic particles in the resin and to excite (and thus heat) the magnetic particles by applying an alternating high frequency magnetic field. The heat from the magnetic particles opens the microporous particles and causes desorbence of the curing agent and then cure of the resin. The invention also provides that the curing agent is absorbed into the absorbent layer in the first place using sonic energy.

    Abstract translation: 本发明提供了应用于地下管线和通道的柔性衬管包括浸渍有可固化合成树脂的吸收材料,其可在管被放置在管道或通道表面上时固化,从而形成管内的刚性管。 通过将固化剂填充到分散在树脂中的微孔或微孔颗粒来控制树脂的固化。 只有当树脂受到诸如声波和/或热能的施加能量时,固化剂才被释放。 优选的方法是将CURIE温度磁性颗粒包括在树脂中并通过施加交替的高频磁场来激发(并因此加热)磁性颗粒。 来自磁性颗粒的热量打开微孔颗粒并导致固化剂的脱附,然后固化树脂。 本发明还提供了使用声能首先将固化剂吸收到吸收层中。
