Title: Apparatus and process for the treatment of timber
IPC: B27K3/10
Filed: 1972-08-22
Abstract: A method and apparatus for the impregnation of timber with a preservative liquid under pressure. The apparatus comprises a vessel for storing the preservative liquid and a vessel for the timber. Pump means are provided for directly transferring the liquid between the vessels. The storage vessel has an upwardly extending portion of relatively smaller cross sectional area which is open to the atmosphere, includes a hydrostatic pressure gauge and means for measuring the level of liquid in the storage vessel. The timber vessel has at its upper end an expansion chamber into which the liquid flows when the timber vessel is full of liquid and has at its lower end a chamber into which the liquid flows when being returned to the storage vessel. Each of the chambers are 8 relatively smaller cross sectional area than the timber vessel. Float switches are provided in the chambers. The apparatus also includes an oscillating pump for accurately drawing a partial vacuum in the timber vessel only, to extract the moisture and air from the timber disposed therein prior to the introduction of the preservative liquid therein. Pumps are provided for thereafter directly transferring the preservative liquid to the timber vessel to completely fill the vessel whereupon some of the liquid enters the expansion chamber. Means are provided for increasing the pressure within the timber vessel after the vessel is full of preservative liquid to cause the liquid to impregnate the timber. A bulk storage vessel is provided and connected to the storage vessel as well as the timber vessel.

Patent ES-419812-A1 (ES)
Title: Process for selectively chlorinating the titanium content of titaniferous materials
IPC: C22B34/12
Filed: 1973-10-19
Abstract: A reduction/chlorination process is provided for the treatment of titaniferous materials such as ilmenite ores. The chlorination is selective in that the titanium constituent of the titaniferous material is chlorinated, but there is no appreciable net yield of iron chloride from the iron constituent. Where other metals such as vanadium are present they may be chlorinated with the titanium. The reduction utilizes as the reductant an amount of carbonaceous material which, based on oxygen in the titaniferous material, is at least stoichiometric to produce carbon monoxide. The selective chlorination utilizes as the chlorinating agent either ferrous chloride (FeCl2) alone or certain combinations of ferrous chloride and one or more other chlorine-containing members, notably molecular chlorine (Cl2) and hydrogen chloride (HCl). The use of ferric chloride (FeCl3) as a part or all of the chlorinating agent is the equivalent of using a FeCl2/0.5 Cl2 mixture. Preferably, sufficient chlorine atoms are provided by the chlorinating agent to react with essentially all of the titanium in the titaniferous material. An elevated temperature in the range of 950 DEG to 1400 DEG C. is maintained during the chlorination, but depending upon the composition of the chlorinating agent, there may be a minimum temperature in the range which is needed to maintain selectivity.

Title: Continuous casting method for the production of rolled low carbon steel products with improved formability
IPC: B22D27/20
Filed: 1977-03-31
Abstract: The relatively poor formability and spot weld fracture appearance of hot-rolled and heavy gauge cold-rolled low carbon steels (in which silicon is the primary deoxidant) have been attributed to manganese silicate stringer-type inclusions, generally found in this product. The addition of at least about 1/8 pound magnesium, per ton of steel cast, is shown to modify this deleterious inclusion morphology, with a resultant improvement in the ductility and weldability of such hot-rolled and the heavy gauge cold-rolled products.
