Title: Inductive sensor
Inventor: CRAIGIE NEIL DR
IPC: H03K17/00
Filed: 1987-09-08
Granted: 1989-03-16
Abstract: The invention relates to an inductive sensor which has a copper screening ring in order to reduce eddy-current losses. The previously known solutions were not yet satisfactory with respect to the overall losses of the sensor and with respect to the switching interval of said sensor. The invention provides a solution for this, in that, in the case of a predetermined internal diameter of the housing sleeve which normally consists of steel, a copper screening ring is arranged at a radial distance from the coil core such that greatly reduced eddy-current losses are achieved in the housing sleeve, with an improved switching interval.

Granted: 1991-05-23
Abstract: The process for producing microcapsules by microencapsulation of hydrophobic oils with substances dissolved or dispersed therein, in particular colour reactants of colour reaction systems, is described, wherein a hydrophobic oil containing the substance in solution or dispersion is mixed under vigorous stirring with an aqueous medium, aminoplast capsules are formed under acidic conditions in the resulting oil-in-water dispersion and these capsules are then isolated if desired, the acidic oil-in-water dispersion containing at least one dispersion-stabilising compound which is not a reactive surfactant. The process is characterised in that the acidic oil-in-water dispersion A) contains a water-soluble anionic, sulphonated melamine/formaldehyde precondensate and/or B) a water-soluble anionically modified melamine/formaldehyde precondensate of a type which has been obtained by   a) reacting, in a first stage, melamine and formaldehyde at elevated temperature in an alkaline medium and in the presence of water with at least one compound (I) in the form of an alkali metal sulphite, alkaline earth metal sulphite, an alkali metal sulphamate, an alkaline earth metal sulphamate, an aminosulphonic acid, aminocarboxylic acid and an aminodicarboxylic acid to give a precondensate, b) subsequently, in a second stage, subjecting this precondensate at a pH of about 5.5 to 7.0 to a polycondensation by acidifying with at least one acidic compound (II) in the form of sulphamic acid, an aminocarboxylic acid, an aminodicarboxylic acid, an hydroxycarboxylic acid, a polyhydroxycarboxylic acid and an aminosulphonic acid, c) after completion of the polycondensation, rendering the resulting resin solution alkaline, if necessary by addition of at least one basic compound (III), and d) including this resin solution, which may be alkaline, in the process for stabilising the dispersion.   This process has the advantage that it requires only a single compound for stabilising the dispersion and does not have to rely on a further compound which loads the system with formaldehyde.
