Title: Pretreatment process for galvanized metal prior to its coating with organic powder.
IPC: B05D3/00
Filed: 1981-03-31
Abstract: This invention relates to a pretreatment process for galvanized metal which, unlike existing processes, was specifically developed for galvanized metal.

Title: Packet switching system.
IPC: H04B3/20
Filed: 1986-03-12
Abstract: In a packet switching system in which speech is packetised, voice activity detectors (VAD's) (2,3) are used to monitor speech in the GO and RETURN paths. In the GO path, the VAD(2) compares the current level of packets with (a) the current background noise value, and (b) the computed value of the expected echo due to speech packets in the RETURN path. If the GO path packet is larger than the parameter of (a) and (b) by a preset arrangement the packet is sent, otherwise it is not. If the "send" decision persists for a number of speech packets, that send condition has a hangover period attached to it. If the parameters are properly chosen, then the speech as heard by a subscriber is not unduly affected.

Patent LU-44888-A1 (LU)
IPC: C08J3/22
Filed: 1963-11-26
Abstract: Polymer - carbon black compositions are formed by a process which comprises forming a solution of a polymer in an organic solvent, introducing a carbon black pelletized with an oleaginous material in a liquid state, agitating the carbon black pellets in the solvent thereby disintegrating the carbon black pellets by dissolving the oleaginous material in the organic solvent and dispersing the carbon black throughout the polymer, and recovering a polymer-carbon black masterbatch.  The process is particularly applicable to those polymers produced by a solution process, e.g. polybutadiene, polyisoprene, butadiene-styrene copolymer, ethylene-propylene copolymer, ethylene-propylene - 11 - ethyl - 1,11 - tridecadiene copolymer, and isobutylene-piperylene copolymer (butyl rubber).  The process is also applicable to solutions of natural rubber and SBR. The oleaginous material may be an oil, liquid polymer, asphalt, vegetable fat or oil, or a resinous material such as rosin in solution in mineral oil.  In a modification, the pelletized carbon black may be mixed with the solvent and added to the polymer solution.  Alternatively the pellets of carbon black may be mixed with a liquid that is a solvent for the oleaginous material but an anti-solvent for the polymer, thereafter the dispersion is added to the polymer solution thereby coagulating the mixture of carbon black and polymer.
