Title: Process for preparing 5-aminonaphthalene-1-sulphamides
Inventor: BUTENAS SAULIUS
IPC: C07C311/16
Filed: 1993-12-30
Abstract: Invention is intended for a production method of a ferment substrate detecting groups, such as 5-aminonaphtalene-1-sulphamids. The invention aims to simplify the production method, increase selectivity, the output of end product and assortment. The aim is achieved directly by producing in acylating a process aminonaphthalene sulphur acid pyridine salts, i.e. acylating by phthalic anhydrite in a boiling pyridine, filtering the fell out of the product, producing sulfonyl chlorides, using phosphorus pentachloride in an organic solvent as chlorodesoxygenation reagent, also by the obtained sulphochloride reaction in acetone with amine or it's water solution in participation of the base, in the reaction process binding formed hydrogen chloride, and by further solvent evaporation, the obtained reaction mix treatment by water, end product separation, removing a protecting group by hydrazine hydrate in a boiling organic solvent. The proposed invention method is more advantageous than the known as there are a reduced number of stages, by declining from the costly reagent of trifluoracetum the end product production is made less expensive and reagent assortment for protease analysis is expanded.

Abstract: A clamping device for attaching crochet needles to the needle bar of a galloon crochet machine or Raschel loom. The clamping device consists of two body pieces, a lower piece and a clamping lid, which are fastened together by means of clamps. In one embodiment the body piece holds the needle shafts, a spacer inserted into each interval between needles, and a support piece between the shafts of a needle and a receptacle in the lower piece. This results in the formation of needle beds. In the other embodiment very shallow grooves are milled opposite one another in both body pieces. These are only a fraction of half the height of the needle shafts, leaving the major part of the needle shaft's height free after clamping.

Abstract: A method of manufacturing a low calorie spread having a relatively high amount of milk fat, in which a protein containing water phase is brought to emulsify in a fat phase comprising butter fat and butter strange oils and/or fats to directly form a water in oil emulsion having a total fat amount 36-40% or more. The preparation of the fat phase is started by cooling cream to a temperature of +3-+15 DEG C and storing the cream at said temperature for a period of between 6 and 24 hours than subjecting the cream to a pressure of such magnitude that the cream emulsion is broken up. The broken cream emulsion is separated on a sieve like plate or drum whereby a fraction of butter particles are collected and a fraction of butter milk is drained. The collected butter particles are heated to a temperature above the melting point of the butter fat and are mixed with the butter strange fats and/or oils and possibly with further fat soluble ingredients, and a water phase comprising a protein concentrate of any known type and prepared in any conventional way is brought to emulsify in said fat phase to provide the water-in-oil emulsion, and finally the emulsion is pasteurized, cooled and packed.
Patent NO-171617-B (NO)
Inventor: CHANDRAN SRIKUMAR R
IPC: G06F11/18
Filed: 1986-05-09
Abstract: The present invention relates to a digital logic circuit and method for synchronizing the leading edges of a skewed true-complement signal pair. The circuit of the present invention is comprised of two similar, interconnected circuit halves, each of which includes three D flip-flop stages. The outputs from the second D flip-flop stages from the two circuit halves are applied to the two inputs of two identical logic gates, such that the signal pair is synchronously transmitted to a pair of output gates through a third D flip-flop stage in each circuit half. The second D flip-flop stages also prevent metastable states from reaching the synchronizer output. Metastable states may result if the input setup time is violated for the first D flip-flop stages. The third D flip-flop stage in each circuit half also eliminates any signal irregularities generated in the logic circuitry from appearing on the synchronizer output lines. The present invention is self-checking in that any single fault in the input signals or in the synchronizer circuit itself will result in the synchronizer output pair not having a true complement relationship.

Abstract: To eller flere signalbaner (30, 32) er fremskaffet for å motta et radiofrekvenssignal. En eller flere signalbaner (30) omfatter vanlige båndpassfiltre (34) for eliminering av forstyrrelses- og støysig-naler. En eller flere gjenværende signalbaner (32) innbefatter reduserte filtreringsanordninger (36) for øking av følsomheten til en radiofrekvensmot-taker i forhold til det ønskede signal. Hver av mottakerbanene (30, 34) er koblet til en respektiv radiofrekvensforsterker (38, 40). Forutsatt at hver radiofrekvensforsterker har ekvivalente strømkilde-utgangsimpedanser, blir utgangssignalene fra hver forsterker addert konstruktivt hvis de er i fase. Hvis utgangssignalene er ute av fase, inverterer en faseinvertor (58) fasen til ett signal, slik at signalene kan adderes konstruktivt. De kombinerte signalene til to eller flere radiofrekvensfor-sterkere (38, 40) passerer gjennom forskjellige signalbehandlingskomponenter knyttet til vanlige superheterodyne mottakere. En styringsenhet (50) fremskaffer ytelsesvariasjonssignaler (52, 54) for styring av ytelsen til hver radiofrekvensforsterker (38, 40). Følgelig vil styringsenheten (50) kontrollere om det ønskede signalet blir mottatt fra en første signalbane, eller andre signalbane, eller som en veiet kombinasjon av to eller flere signalbaner.
