Patent ES-8300305-A1 (ES)
Title: A process for producing silica and use of same.
IPC: C08F4/02
Filed: 1981-05-20
Abstract: A method comprising combining a silicate ester and water under hydrolysis conditions in the presence of a sufficient amount of solvent that the reaction mixture remains as a single phase, adding sufficient acid neutralizing agent to form a gel and separating solvent and water from the resulting silica. In a preferred embodiment, the ester and water are added to a very small amount of solvent, the addition of water being sufficiently slow that it is added at about the rate it is used up in the hydrolysis reaction. The resulting silica does not require the washing step to remove alkali metal ions since it is not made from sodium silicate, and it has large pore structure because it can be made in a relatively concentrated solution because of the use of only a minimum amount of solvent and also because the hydrolysis is carried out under conditions wherein only a single phase is produced. The resulting silica is suitable for chromatographic columns and fillers in rubber and plastics but is of primary utility as a base for a chromium oxide catalyst because of its simplicity in production and inherent large pore volume.
Patent ES-8205488-A1 (ES)
Title: Keying signal generator with false output immunity
IPC: H04N9/455
Filed: 1981-08-21
Abstract: A circuit for generating a composite keying signal comprises a gate pulse generating circuit and a voltage translating network in a television receiver also including keyed video signal processing circuits. The composite keying signal comprises a first pulse developed by the translating network during horizontal blanking intervals of the video signal, and a second pulse developed by the gate circuit during a portion of the horizontal blanking intervals and superimposed on the first pulse. An output of the gate circuit is clamped during picture intervals to a fixed voltage via a low impedance clamping path that exhibits current conduction capability greater than the output current conduction capability of the gate pulse generating circuit. The clamping action prevents improper keying of the keyed circuits in response to false keying signals such as may be generated in response to spurious signals occurring during picture intervals of the television signal.

Title: Process for recovering zinc from zinc ferrite material.
IPC: C22B19/00
Filed: 1981-12-04
Abstract: A process for recovering zinc from material containing zinc ferrite includes leaching the ferrite containing material together with zinc sulphide containing material in a leach step, with the relative amounts of ferrite material and zinc sulphide material being such that the zinc present as zinc ferrite is a minor proportion of the total zinc content of the ferrite material and the zinc sulphide material. The leach step is carried out in aqueous sulphuric acid solution at elevated pressure under oxidizing conditions and at a temperature above the melting point of sulphur, with the sulphuric acid to zinc molar ratio being less than about 1.2:1, to cause dissolution of a substantial amount of zinc from the ferrite material and from the sulphide material.

Patent ES-8501511-A1 (ES)
Title: Reducing losses in combustion operations.
IPC: F23N1/02
Filed: 1983-10-27
Abstract: A method of minimising combustion operation losses includes measuring (40) a load index for the combustion operation which is proportional to the fuel demand or the output thereof, measuring an amount proportional to the air heating losses of the combustion operation and measuring an amount which is proportional to the fuel loss of the operation. The air heating loss is measured by multiplying (34) a flue temperature (30) by an amount of unburned oxygen in the flue gas. This quantity is multiplied (42,44) by a cost factor for such air heating and the load index. The fuel loss is obtained by measuring (46, 48, 50) an amount of by-product in the flue gas as well as the opacity of the flue gas. These are multiplied (56, 58, 60) by appropriate cost factors which in the case of opacity is proportional to a fine that would be due for violating certain limits for the opacity. Minimum values are found for the fuel loss and air heating loss quantities, as air demand to the combustion operation is changed. A minimum for the sum of the fuel and air heating losses is also obtained with the air demand of the combustion operation being set so that all of the losses are as low as possible. In this way the costs of undesired air heating, unburned by-products as well as potential violation of flue gas characteristic limits are utilised in determining the most economical air demand for the combustion operation.
