Title: Dispersion process and product.
IPC: C08F283/00
Filed: 1981-07-02
Abstract: Preparation of aqueous dispersions of film-forming polymer particles wherein the dispersions comprise both pre-formed polymer and polymer formed in situ, and to the use of these dispersions in coating compositions which can be applied by cationic electrophoresis. Previous dispersions of the general type hereinabove described can be cationically electrodeposited but do not give films of adequate integrity and adhesion. The present invention overcomes these drawbacks by using a process wherein (a) pre-formed polymer or polymer plasticiser is dissolved in polymerisable monomer and the resulting solution stably dispersed in water in the presence of a surface active agent, and (b) the monomer is polymerised to give a particulate dispersion. Prior to polymerisation the dispersion must comply with specific pH requirements involving ensuring instability within the pH range 10-11 and the surface active agent must be cationic and have an H.L.B. value of at leat 8.

Abstract: The present invention relates to lacquer polyisocyanates which contain about 0 to 8% free isocyanate groups, about 10 to 28% blocked isocyanate groups and about 2 to 10% of the structural units, -NH-NH-CO-O, all percentages based on the weight of the polyisocyanates, but excluding the weight of the blocking agent. Also provided is a process for preparing these polyisocyanates which comprises reacting about 10 to 30 mol % of the isocyanate groups of an organic polyisocyanate with reaction products which have (i) alcoholic hydroxyl groups and (ii) structural units of the formula, -O-CO-NH-NH-CO-O-, and/or of the formula H2N-NH-CO-O-, with the formation of urethane groups and optionally groups corresponding to the formula, -NH-NH-CO-O-, and reacting about 50 to 90 mol % of the isocyanate groups of the organic polyisocyanate with a blocking agent. The reaction products containing alcoholic hydroxyl groups are obtained by reacting 1 mol of hydrazine or of hydrazine hydrate with about 1 to 2 mols of a cyclic carbonate. A final object of the present invention is the use of the new lacquer polyisocyanates as the isocyanate component in thermosetting, two-component polyurethane lacquers.

Title: Vertical deflection device with voltage control loop and television receiver comprising such a device.
IPC: H03K4/62
Filed: 1982-01-22
Abstract: Device for a television receiver in which the energy required to generate the current crossing the vertical deflector (9) is drawn from the line return pulses with the aid of a filtering means (4, 8) in series with a controlled breaker (5, 6, 7) which, in each line, is conductive for a time which depends on the index of this line, the vertical deflector (9) being in series with a linking capacitor (10) whose average voltage across its terminals is maintained substantially constant with the aid of a static regulating loop (30). The voltage across the terminals of the linking capacitor (10) is introduced into the static loop via a sample-and-hold circuit (34, 40) which, in each vertical scan return period, stores a signal representing a voltage and maintains the latter practically constant for the vertical scan period, and which is preceded by a correcting network (41, 41a) making it possible to increase the open-loop gain of the static loop.

Patent ES-8402234-A1 (ES)
Title: Aluminum hydroxide chloride hydrate complex and manufacture
IPC: C01F7/57
Filed: 1982-12-02
Abstract: In some diseases, in particular in kidney disorders, absorption of the phosphate taken up with the food must be largely avoided. The aluminium chloride/hydroxide hydrate complexes according to the invention bind phosphate to a high extent in the intestinal tract and therefore largely prevent absorption of the phosphate. The aluminium chloride/hydroxide hydrate complexes described can therefore be used as medicaments for phosphate binding.

Title: Composite material based on fragments of vegetable origin and process for the production thereof
IPC: C08L97/02
Filed: 1983-11-18
Abstract: The invention relates to a composite material based on pieces or particles based on lignocellulose, for example wood elements, veneer sheets, woodchips, wood shavings, tree bark, maize cobs, maize stalks, straw and the like, which contain polysaccharides, lignin, tannins, essential oils etc. and are firmly connected together. The process according to the invention for producing this composite material is based on applying an activating agent, especially sulphuric acid, to the starting material, the action of which transforms the polymeric matrix material into active monomers. Excess activating agent is neutralised if necessary by the addition of a deactivating agent or neutralising agent, for example of pulverulent urea. Subsequently the activated parts are brought into contact with one another and compressed with the supply of heat, the activated monomer material being repolymerised to form a polymer of similar structure to the matrix of the starting material with crosslinking, causing the particles of the starting material to be bonded together. The activation effect can be increased by addition of a catalyst, for example potassium permanganate. The binding effect of the binder produced from the matrix material of the starting material used can, by the addition of furyl alcohol, furyl aldehyde, furyl acetone or phenols or of precondensation products thereof ...

Title: Method and apparatus for offshore electromagnetic sounding utilizing wavelength effects to determine optimum source and detector positions
IPC: G01V3/15
Filed: 1984-11-20
Abstract: An improved method and apparatus for electromagnetic surveying of a subterranean earth formation beneath a body of water. An electric dipole current source is towed from a survey vessel in a body of water substantially parallel to the surface of the body of water and separated from the floor of the body of water by a distance less than approximately one-quarter of the distance between the surface and the floor. Alternating electric current, preferably including a plurality of sinusoidal components, is caused to flow in the source. An array of electric dipole detectors is towed from the survey vessel substantially collinearly with the current source. Each electric dipole detector of the array is separated from the current source by a distance substantially equal to an integral number of wavelengths of electromagnetic radiation, of frequency equal to that of a sinusoidal component of the source current, propagating in the water. A gradient detector array is also towed by the survey vessel in a position laterally separated from, or beneath, the mid-point of the current source. Additionally, an array of three-axis magnetic field sensors mounted in controllable instrument pods are towed by the seismic vessel on the flanks of the current source. Frequency-domain and time-domain measurements of magnetic and electric field data are obtained and analyzed to permit detection of hydrocarbons or other mineral deposits, or regions altered by their presence, within subfloor geologic formations covered by the body of water.
