Title: Steroid compounds
IPC: C07J75/00
Filed: 1956-01-10
Abstract: The invention comprises retrocortin phosphate compounds of the general formula <FORM:0826365/IV (b)/1> wherein R is a keto or a b -hydroxy radical, and Y is a hydrogen or halogen atom, their ammonium, and alkali and alkaline earth metal salts, and a process for their preparation by reacting the corresponding retrocortane 21-phosphate compound with bromine and treating the resulting 2,4-dibromo derivative with a dehydro-halogenating agent, e.g. collidine.  The retrocortane 21-phosphate is in turn prepared from the corresponding free 21-hydroxy compound by the steps of (a) protecting the 3-keto group by ketalization, e.g. with ethylene glycol; (b) reaction of the ketal with an organic sulphonyl halide; (c) treatment of the resulting 21-sulphonate with an iodide salt; (d) reaction of the resulting 21-iodide with an organic phosphate; (e) catalytic hydrogenation of the 21-organic phosphate compound in the presence of a tertiary amine, giving the amine salt of the retrocortane 3-cyclic ketal-21-phosphate, from which (f) the ketal group is split off by acid hydrolysis.  In examples: (1) retrocortane and the dioxolane of mesityl oxide are reacted to yield retrocortane 3-ethylene ketal, which with mesyl chloride and pyridine gives the 21-methane sulphonate; subsequent reaction with sodium iodide in ethanol gives 21-iodo-21-desoxyretrocortane 3-ketal which is reacted with silver dibenzyl phosphate, the resulting 21-dibenzylphosphate hydrogenated with N-methyl morpholine over palladium oxide to the N-methyl morpholine salt of retrocortane 3-ethylene ketal 21-phosphate, hydrolysed to retrocortane 21-phosphate, dibrominated to the 2,4-dibromo derivative and then refluxed with collidine to give retrocortin 21-phosphate; (2) to (4), as in (1) hydro-retrocortane, 9-fluoro-retrocortane and 9-fluoro-hydro-retrocortane similarly yield the 21-phosphates of hydroretrocortin, 9-fluoro-retrocortin and 9-fluoro-hydroretrocortin respectively and which are characterized as their sodium or potassium salts.  Retrocortane is prepared by hydrogenation of D 4 - 3,11,20 - triketo - 17a  - hydroxy - 21-acetoxypregnene over palladium oxide, and saponification of the resulting retrocortane 21-acetate; hydroretrocortane and the corresponding 9-fluoro derivatives are prepared by similar methods.

Abstract: 1,135,956. Treating eyes. INTERNATIONAL RESEARCH & DEVELOPMENT CO. Ltd. 29 Dec., 1966 [7 Jan., 1966], No. 931/66. Heading A5R. [Also in Divisions AS and H1] In a laser ophthalmoscope the laser output beam and an aiming spot formed by a light source and optical system are brought to a common focus on the target area. Light from source 5 is collimated by lenses 6, 7 and reflected by mirror 8 onto apertured mirror 9 lying into the path of the output beam from ruby laser 3. After being brought to a focus on mirror 11 by lens 10 the light beam is directed onto the patient's eye 13, the aperture 9a appearing on the retina as a dark spot in the illuminated area. The optical axes of the output beam from laser 3 coincides with the light beam from source 5 and the laser beam after passing through aperture 9a, lens 10 and being reflected by mirror 11 is brought into focus on the retina by lens 15 of eye 13. An observation outlet 16 is provided offset from aperture 12 so that no substantial reflection of the laser beam can fall on the observer's eye. Defects in the patient's and/or observer's eyes can be corrected for by correcting lenses 18. Focussing of the laser beam is achieved by adjusting the position of lens 10. Reference has been directed by the Comptroller to Specification 1045868.

IPC: B41M5/165
Filed: 1995-03-02
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.

Filed: 1990-01-05
Abstract: PURPOSE:To eliminate the need for a separate circuit by employing an FET having a side gate electrode as a nonlinear device, and supplying a converted signal to a gate electrode and a local oscillation signal to the side gate electrode. CONSTITUTION:The threshold voltage of a field effect transistor(FET) 1 is fluctuated depending on a voltage applied to an electrode (side gate electrode) 50 arranged near the gate electrode, but in such a case, the side gate effect is, in turn, utilized positively. That is, a local oscillating signal VOSC is supplied to the side gate electrode 50 to vary the threshold voltage Vth of the FET 1. The drain current of the FET is made intermittent by the local oscillating signal by setting a gate bias voltage Vb to be nearly (Vth1+Vth2)/2 (range of the change is (Vth1 to Vth2) to attain mixing. Thus, no separate circuit is required.
