Abstract: The invention relates to a process for the purification of 1,4-benzoquinone-guanylhydrazone-thiosemicarbazone (ambazone) in two steps. In the first step, there takes place the removal of sulphur from ambazone by maceration of ambazone in a non+polar solvent (benzene, n-hexane, toluene or xylene). In the second step, there takes place the recrystallization of ambazone from a mixture of N,N-dimethylformamide and lower aliphatic alcohols (C1-C4) at a temperature ranging from 50A to 80A C.

Title: Process for obtaining an assortment of demi-sec white wine from "columna" variety grapes
Inventor: GHI E MARIN
IPC: C12G1/02
Filed: 2004-11-25
Abstract: According to the invention, the process for obtaining demi-sec wine from COLUMNA variety grapes consists in that, in order to highlight the orgaloleptic properties of this new variety and to transmit them to the so obtained wine, the grapes are harvested when technologically mature, in the period 5-10 October, when the grape sugar concentration is of 204 ... 213 g/l of wine pressing and an acidity of 6.8 g/l, and are subjected to technological steps of wine preparation such as: sulphitation, grapes removing from cluster-crushing, separation by pressing, wine blending-homogenizing, clarification, alcohol fermentation and drawing wine from sediment with the mention that the free run grape juice is blended and homogenized only with the first wine pressing, followed by treating with enzymes concomitantly with cooling the same to 6 ... 8A C for rapid settling of the coarse particles from the juice and cutting the wild yeasts activity, then clarified and seeded with selected yeasts, the alcohol fermentation taking place first at the room temperature of 20 ... 24A C up to reaching an alcohol concentration of 2.5 ... 3% by volume of alcohol, then at controlled temperatures of 15 ... 16A C , in order to lower the yeast concentration, and when the alcohol concentration reaches 10.2 ... 10.5% by volume of alcohol, the fermentation is ceased by lowering the temperature to 8 ... 10A C, the process following thereafter in a manner known per se, for obtaining a demi-sec wine.

Title: Butt for sporting gun without recoil
Inventor: CAAENCIU VASILE
IPC: F41C23/00
Filed: 2005-03-22
Abstract: The invention relates to a combined gun butt, without recoil, meant to equip a sporting gun of middle or big size, with shot cartridge or bullet cartridge. According to the invention, the butt comprises a head of sporting gun, without recoil (A), a fixed non-deflecting module (B) and a recoil-preventing mechanical module (C), fastened by a vertical screw (3), but also by means of some long fastening screws (6), thus, at the shooter's wish, there is created a gun butt with recoil.

Title: Installation for thermo-mechanical fatigue testing of alloys with shape memory
Inventor: VIZUREANU PETRICĂ
IPC: G01N3/60
Filed: 2011-06-16
Abstract: The invention relates to an installation used for fatigue testing by combined thermal and mechanical stress of the alloys with the shape memory. According to the invention, the installation combines the thermal cycles at temperatures of maximum 150°C, with tensile test of the specimens (1) with standardized shape for determining the approximative number of operating cycles of an element, until there occurs the deterioration of the shape memory properties and, at the end, the material breaking, the installation being conducted by a computer program (12) by means of a control panel (13), the combined thermo-mechanical stress occurring inside a metallic enclosure (7) heated by means of the system (5 and 6) and the weights (4), and a motor-reducer (11), respectively.
