On sait que les batteries conventionnelles, fabriquées d'alliage de plomb, sont habituellement remplies d'acide sulfurique. La présente invention consiste en un nouveau genre d'électrolyte qui remplace complètement ces acides. Il est composé de jus de fruits et de jus de graines de fleurs, c'est-à-dire qu'il ne contient aucun produit chimique. Un tel électrolyte peut être utilisé dans toutes les b...

La présente invention concerne un procédé de préparation de la vitamine A qui consiste à faire réagir l'éthynyl .beta. ionol avec l'acétal d'un halogénure allylique en C5 en présence d'une quantité catalytique de cuivre, à réaliser une hydrogénation modérée du dérivé obtenu, à éliminer la fonction hydroxyle et à redresser le rétinal obtenu.; Prodn. of vitamin A comprises: (a) reacting ethynyl-beta...

A method (250) for determining camera-induced scene changes in a sequence of visual information-bearing frames which constitute a single shot first determines (400) camera-induced motion between each of a plurality of pairs frames within a single camera shot. The camera-induced motion for each of the pairs of frames is decomposed (410) into at least a first component (420,430,440). The values of t...

This invention concerns a container package for dental floss or tape that is both a dispenser and a display, for example, for points of sale.

The device comprises two tines 1-2, which can be elastically spread apart to contain, in a suitable internal conformation 5, the optical attenuators for SC-2 optical connectors and automatically tighten them for extraction.

The device consists of a perforated cylindrical structure 1, with internal diameter greater than that of the central stem B of the press, so as to allow, after the piston descends, a straining of the must both on the external surface and in the central zone, with means 3 and/or 6 for subsequent collection of same, along with the must obtained by the traditional exit from the external surface.

The invention consists of a beam comprised of a steel web 1, realised with a profiled piece stretched at the bottom, provided with a concrete slab 18 with which the lower part 2 of the profile 1 itself is buried and in a method of production which utilises a steel profile 1, which at rest has the lengthwise curved profile with its concavity facing downwards, a resistant base structure 4 which comb...

Portable piercing machine comprising a head with a plurality of perforating tools drawn simultaneously by an electric motor and a frontal positioner consisting of a plate sliding parallel to itself and served by contrasting springs, with through holes aligned with the tools, to obtain multiple simultaneous perforation by resting the positioner on the object to pierce and pressing the head against ...

The process uses rollers to carry the paper (1) in a flat plane past two cameras (2,3) with associated light sources (4,5).The transport mechanism is designed with suitable windows allowing optical aces to each face of the paper. The paper remains flat as it passes across each camera. A third camera (6) and light source (7) measures light passing through the paper to determine its transparency.

A process for the O-benzylation of phenols and the alpha- mono-C-benzylation of CH2 acid compounds with dibenzyl carbonate DBz 1C) in order to obtain benzylphenyl ethers, α benzylarylacetonitriles and 2-aryl-3-phenylbenzyl propionates respectively is described

Hydroisoquinoline derivatives of general formula I and a process for their preparation and use as active ingredients having analgesic, immunomodulating and cardiovascular activity are described.

Hydroisoquinoline derivatives of general formula I and a process for their preparation and use as active ingredients having analgesic, immunomodulating and cardiovascular activity are described.

The use of [11 β[(-dimethylamino)phenyl]-17 β- hydroxy-(17α-1-propynyl)oestra-4,9-diene-3-one], also known as mifepristone, having the formula as an agent stimulating the production of endogenous alpha interferon and its application in the treatment of viral and tumoural infections is described.

Intensive vertical store provided with a system for measuring the dimensions of the object as it enters the store, consisting of a vertical support on which opto- electronic detectors are fitted, with the possibility of rotation and which can be rotated 90 degree around its own axis. The store comprises a storage compartment self-adjustment mechanism and an opto-electronic device for picking up th...

The warped blade for axial fans has a blade profile with segmented sections and at least the part of the blade with the leading edge subtended from the associated tip segment arranged at an angle variable between 0 degree and 20 degree with respect to the plane of rotation of the blade. There are preferably four segments and the part of the blade with the leading edge is divided by an oblique line...

Disclosed is a software generation system (SGS) based memory error detection system which may be utilized to detect various memory access errors, such as array dimension violations, dereferencing of invalid pointers, accessing freed memory, reading uninitialized memory, and automated detection of memory leaks. Error checking commands and additional information are inserted into a parse tree associ...

Battery charger for cylindrical cells which comprises a substantially cylindrical housing with respective bottom and upper parts separated by a pair of opposing recesses. In operation the housing is arranged in upright position and the recesses have planar rear faces extending in parallel with each other and with the axis of symmetry of the housing. Spaced guiding ribs are provided at upper and lo...
