Title: Improvements in the moulding of organic materials
IPC: B29C45/00
Filed: 1936-07-01
Abstract: 465,234. Injection moulding. CELLULOID CORPORATION. July 1, 1936, No. 18203. Convention date, July 2, 1935. [Class 87 (ii)] Thermoplastic organic materials are moulded by injecting a heated stream of material through a channel into a mould cavity and, before the material enters the cavity arresting the leading end of the stream in an auxiliary cavity connected with the mould and channel so as to form a protuberance capable of being removed from the moulded article. In moulding spectacle frames the mould comprises a rear section 1 and a front section 2'having a mould space 3 between them. The nozzle of the injecting device engages a port 10 and forces the material down the channel 5 into the mould through branch channels 6. More than one channel 5 may be provided. The channel terminates in an auxiliary cavity 7 which is shaped so as to form a tapered head on the article to retain it in the mould section 1 when the mould is opened. The article may be ejected from the open mould by a pin bearing against the head through a hole 4. Additional cavities 9 may be provided in the mould at points remote from the channel 5 to receive the leading end of the material passing through the mould cavity. The protuberances thus formed on the moulded article can be easily broken or cut off. The material may comprise chlorinated rubber, polymerized vinyl compounds, styrol, acrylic esters, and cellulose derivatives and various articles may be produced such as switch plates, buttons, fountain pen barrels, ornaments, &c. Specifications 385,999 and 460,078 are referred to.
Patent GB-1002019-A (GB)
Title: A process for the production of paper or paper-like sheet materials
IPC: D21H/
Filed: 1964-05-01
Abstract: Paper containing fibres of polyamide and of cellulose is made by treating the polyamide fibres with an acidified aqueous solution of the sodium salt of a copolymer of styrene and maleic acid, forming an aqueous dispersion of fibres of the two kinds, and processing this dispersion on a paper-making machine.  The solution may be prepared by treating the polymer with sodium hydroxide, dissolving the soluble products in water, and then acidifying, but not so strongly that the copolymer is precipitated.  A preferred range of pH is 1.8 to 2.5. The polyamide fibres may be treated by drawing a stretched tow through the solution, or they may be treated after cutting. Alternatively the tow may first be drawn through a dilute acid, and then squeezed and drawn through a solution of the polymer which has not been acidified and is kept at constant pH by the continuous addition of alkali.  The treated fibres can be stored dry or moist.
