    • In making thermosetting moulding compositions, urea, melamine, biuret or thiourea is mixed with substantially dry paraformaldehyde and an absorbent cellulose filler, and heated in a closed vessel at a temperature sufficient to bring about condensation with liberation of water, which, when condensation is complete, is allowed to escape from the vessel as vapour, thereby cooling the mixture and stopping reaction. Fillers mentioned are wood-flour, sulphite pulp or a -cellulose. Curing catalysts, e.g. epichlorohydrin and, if desired lubricants, dyes, pigments or plasticizers are added, preferably to the cooled mixture. If desired the charge may be transferred to a second mixer, preferably having a cooling jacket, at the beginning of the cooling. The moulding composition is densified into lumps and freed from remaining traces of water by mixing or kneading in heated apparatus, and then granulated or ground. In an example urea, paraformaldehyde, a -cellulose, ammonia, hexamine, zinc stearate and pigments or dyes are mixed in a jacketed ribbon-typemixer which is closed and heated to 200-230 DEG F. After reaction, the mixer is opened. Vapours escape and the temperature falls to 180 DEG F. Additional hexamine and epichlorohydrin or other latent catalyst is added and the mixture transferred to a cooled mixer and thence to a heated densifier provided with a suction fan to remove remaining water. The material is discharged on to a conveyer to a crusher to cut it to small pieces and then to a second cutter for final granulation. Triethanolamine may replace ammonia as buffering alkali. When the proportion of filler or pigments used is high, a small quantity of water may be added to the initial mix to facilitate uniform admixture. The granulated product may be ground to a fine powder, and colouring materials may be added at this final grinding stage if desired.

    • Systems and methods for creating and employing software to handle the playback of media, especially video, in browsers that, in addition to or instead of playing the media in the browser, may use second display protocols to instruct a separate display device to play the media. In one implementation, the software may be in the form of a web or other application. In particular, systems and methods are provided that describe ways to clean up bad assets from favorites or recently-viewed lists. In one implementation, systems and methods are provided that use an erroneous asset report from one user to fix other users' associated lists. In another implementation, the systems and methods employ data about defunct services, both local and global, to remove assets from those services from one or more user lists.
