Title: Method and system for feeding cows
Inventor: LUNDIN SOREN
IPC: A01K11/00
Filed: 1991-01-16
Granted: 2002-08-27
Abstract: When feeding cows with a fodder supply containing roughage and concentrate fodder, the cows are allowed to consume optional quantities of roughage, while the concentrate fodder is distributed to the cows in individual restricted quantities, the proper concentrate fodder ration administered to each cow being influenced by the actual roughage consumption of the cow. Ac-cording to the invention, the maximum roughage consumption of each cow is measured during an initial predetermined part of the lactation period of the cow, the concentrate fodder ration to be administered to the cow during the remaining pan of her lacta-tion period is determined in response to said maximum roughage consumption, and the determined concentrate fodder ration is fed to the cow during the remaining pan of her lactation period.

Title: Image editing system and method having improved automatic object selection
Inventor: CAMPANELLI MICHAEL R
IPC: G06F3/033
Filed: 1992-09-01
Granted: 1997-06-24
Abstract: An image editor stores color pixels for an image to be edited in an image pixel buffer and a lookup register bank.  The stored image is displayed on a monitor.  An operator uses a mouse to designate a screen path that identifies an object in the image, and pixel position data is detected for the screen path.    A programmed computer determines in real time one or more criteria for a search controller on the basis of hue, saturation and luminance variables which are determined from the stored pixel color data for pixels along the screen path.  The computer further searches the image pixels to identify the object and its boundaries in accordance with the search controller criteria, and applies color edit actions to the identified object within the image.

Title: Non-contact type ic card
Inventor: KOBAYASHI YOSHINORI
IPC: G06K19/07
Filed: 1992-05-21
Granted: 1996-09-17
Abstract: In a non-contact type IC card, a re-access inhibition time setting circuit sets a re-access inhibition period of time for inhibiting the re-access for a fixed period of time after an operation of a main circuit 16 is finished. Thisprevents a double write operation of history in the card due to re-access withina short period of time. Moreover, two areas are disposed in a memory, and data are alternately written in these areas. In a read operation, if data from one ofthe areas is corrupted, the normal data in the other area is read; whereas, wheneach data is normal, the data last recorded is read. Consequently, a disabled state of a read operation due to corrupted data can be prevented.

Abstract: Dans un gyroscope à fibres optiques (10) comportant une paire d'ondes lumineuses se contre-propageant dans une boucle à fibres optiques (44), un modulateur de phase (28), commandé par une fréquence variable et par un signal de modulation d'amplitude sur une ligne (32) de façon à rendre nulle toute rotation induite par un décalage de phase optique et à utiliser la différence entre la fréquence de commande et la fréquence propre de la boucle comme une mesure de vitesse de rotation, est pourvu d'un circuit d'étalonnage (34) qui détermine la fréquence propre réelle de la boucle en rotation. On applique un signal de modulation ayant une amplitude qui provoque l'égalisation entre la fréquence de sortie en boucle fermée et la fréquence propre de la boucle indépendamment de la vitesse de rotation. On accorde avec précision l'amplitude en appliquant un signal de tremblement de phase et en réglant l'amplitude jusqu'à ce que les effets du signal de tremblement soient réduits au minimum.

Title: Image analysis for meat
Inventor: BENN ALAN
IPC: A22B5/00
Filed: 1993-04-13
Granted: 2002-12-31
Abstract: A process and apparatus for identifying a target section within an image of a meat section (12). Colour data for each pixel is stored and the pixels having a predetermined colour characteristic of the target section e.g. a certain red/green ratio, arc discri-minated. The process involves excising from a refined data set for the discriminated pixels at least one data set for a cluster of pixels representing an external image section which is adjacent to and contacting the target section but which dons not form part of the target section, the excising step including analysing the shape of the refined image section represented by the refined data set to identify concavities and examining properties of links and/or properties of sub-sections formed by links to identify valid links demarcating the target section from adjacent touching external image sections, The refined data set after the excising step has been carried out is processed as the data set representing the target section of the image.

Title: Process for the preparation of iodinated biopolymers having disinfectant and cicatrizing activity, and the iodinated biopolymers obtainable thereby
Inventor: DE ROSA ALFREDO
IPC: A01N59/12
Filed: 1994-04-28
Granted: 2005-06-14
Abstract: Process for the preparation of complexes of iodine with chitosan or derivatives thereof, and the iodinated compounds thus obtainable. Said compounds take form of powders, which may contain over 60% of iodine in its elementary form. In a dry state the iodine bound to the chitosan or derivatives thereof does not sublimate. If the percentage content of iodine does not exceed 50% (by weight), said powders can be dissolved in aqueous solvents of an acid type, such as, for example, diluted acetic acid or glutamic acid. Said solutions are compatible with addition of surfactants, preferably of a non-ionic type, which improve the solubility of the chitosan-iodine complex. Solutions with identical characteristics can, alternatively, be prepared by solubilizing, heating if necessary the iodine in a suitable surfactant, preferably non-ionic, and adding this solution under rapid stirring to the chitosan derivatives thereof, dissolved in water, optionally in the presence of acids or salts. Alternatively, the chitosan or derivatives thereof in a dry state can be added to the solution of iodine in surfactant which rapidly absorbs onto the solid, forming the chitosan-iodine complexes. This material suspended in water or in acid solutions, preferably acetic acid or glutamic acid, solubilizes rapidly. The complexes of iodine with chitosan or derivatives thereof, in the form of aspersable powders, solutions or ointments, thanks to their disinfectant and cicatrizing properties, can be used in the field of surgery post-operative treatment and more generally speaking as products for topical use for medication of wounds and disinfectation of the skin. Another area of interest in which the complexes can be used as an active principle is the field of cosmetics.

Abstract: A beta-alumina solid electrolyte for use in sodium-sulfur battery is composed of the beta-alumina crystals having a degree of orientation toward C axis, of 0.2-0.4 and an aspect ratio of 4.0 or less.  The beta-alumina solid electrolyte is composed of the beta-alumina crystals having a degree of orientation toward C axis, of 0.2-0.4 and has such a particle diameter distribution that the average particle diameter is 3 µm or less, the proportion of the particles having a particle diameter of 5 µm or less is 90% or more, and the maximum particle diameter is 300 µm or less.  A process for producing a beta-alumina solid electrolyte using an alumina source material, a magnesium source material and a sodium source material has using a magnesium-aluminum spinel as the magnesium source material and subjecting all materials to mixing, granulation, molding and firing to obtain a beta-alumina solid electrolyte without subjecting the materials to calcination.  The beta-alumina solid electrolyte has a low electrical resistance and a large strength to internal water pressure and exhibits excellent properties when used as a diaphragm for sodium-sulfur battery.

Granted: 1997-06-10
Abstract: A pliers-like hand tool is provided for removing  plastic grommets or other similar insert members embedded within concrete during a post tensioning or other forming process of concrete construction. The hand tool includes two hand members each having a  jaw end portion,  handle end portion and intermediate neck portion, being pivotally connected between the neck portion in a well known structure for gipping a workpiece between the jaws. A fulcrum protrusion is formed with the tool at a point near the jaw ends and acts to provide a bearing on the concrete for a leverage action which is caused by pressure being applied to the handle ends against the concrete in order to extract the grommet which has been gripped between the jaws of the tool. It makes the removal of grommets easier in a labour-and-time-saving way. It is also helpful to preserve the grommets for future   use.
