Title: Preparation of decorative plastics articles
IPC: B29C43/20
Filed: 1973-12-31
Abstract: 1459230 Moulding multicoloured plastics articles ALL DECOSTONE NV 31 Dec 1973 [26 April 1973] 60223/73 Heading B5A A method of producing a multicoloured decorative plastics article utilizes a moulding composition which comprises, in addition to an uncured thermosetting resin binding agent and filler materials, particles of a coloured polymer which is soluble at least in part in the binding agent; the moulding conditions are controlled to allow the polymer to dissolve to a predetermined degree to obtain the desired effect. The preferred binding agent/filler system is a fibre reinforced unsaturated polyester moulding compound, and in this case the polymer particles are preferably a styrene polymer or polyvinyl acetate. In these two examples, dissolution of the polymer particles occurs during a waiting period in which the mixture of polymer particles and moulding compound is allowed to stand before being compression moulded. Alternative resin systems are: a linear polyurethane particle in a polyurethane prepolymer, or polyvinyl alcohol particles in an epoxy resin prepolymer. The incorporated polymer particles may be granular, flaky, elongated or threadshaped of size 0À1-10 mm., and used in an amount 0À1-20% by weight based on the binding agent. To further enhance the decorative effect, a mineral filler (quartzite, mica, corundum) of grain size up to 3 mm. may be used, giving for example a natural stone appearance to the article.

Title: Cooling and neutralising acid gases
IPC: B01D50/00
Filed: 1979-06-13
Abstract: In a process for neutralizing hot acid gas, the gas prior to being neutralized is introduced 24 into a zone, e.g., one or more cyclones 14, 16 arranged in parallel, to establish an upwardly, generally spiral gas stream for removal from the gas of larger particles which concentrate at the cyclone wall by centrifugal forces. The resulting upwardly- moving cleaned gas stream or streams which may or may not have a spiral motion is contacted with an upwardly- moving spray of a basic neutralizing liquid or slurry e.g. from nozzles 46, 48, under conditions such that the spray droplets moderately overcome gravitational forces such that they experience a sufficiently long residence time in a reaction zone 12 above the nozzle(s) to be evaporated to dryness with resultant cooling and neutralisation of the gas. The product gas from the reaction zone then can be treated further to remove small particles and salt product and for residual acid gas.

Patent GB-2045374-A (GB)
Title: Standpipes for hydrants
IPC: F16L13/16
Filed: 1980-03-12
Abstract: The invention relates to standpipes for water hydrants. Hitherto standpipes have been constructed as a metal tube secured at its lower end to a base or socket by welding to ensure a leak free joint. This has the disadvantage of reducing the mechanical properties of the tube thus necessitating the use of thicker walled tubes than would otherwise be necessary. The objective of the invention is to avoid welded constructions, and this objective is met in a construction comprising a tubular body (1), the lower end of which fits into a separately formed socket or base (2), part of the tube within the socket having been expanded into contact with the inner wall of the socket, which inner wall is provided with formations (4 and 5) whereby following expansion of the said part of the tube, the tube and the socket become mechanically interlocked to form a leak-proof joint. <IMAGE>
