Inventor: MILLER VAN
IPC: A23C19/086
Filed: 1994-03-03
Abstract: This invention provides a cheese-based dry flake product for incorporation into baked goods and flour confections, and methods of manufacture. The dry flake product comprises from 0 to 2 % moisture, from about 20 % to about 50 % cheese solids, and the balance is a cheese-compatible and bakery-compatible oil that is substantially liquid at about 40  DEG C and as much as 43 % to 66 % of solid fats balance liquid fats, at about 10  DEG C. The cheese solids are naturally occurring cheese solids derived from cheeses from which substantially all water has been removed, and thereby comprise the butterfat, protein and lactose constituents of cheese. The cheese-compatible and bakery-compatible oil is chosen from the group consisting of suitable vegetable oils and butter oils, and mixtures thereof, which exhibit generally similar solid fat index and melting points as those of butterfat. Moreover, the cheese-compatible and bakery-compatible oil is miscible with the butterfat constituent of the cheese solids, in any proportion, at temperatures of about 35  DEG C to about 40  DEG C, so as to make a substantially homogenous mixture therewith, in which the protein and lactose constituents are held in suspension. The method of manufacture provides for mixture of the ingredients so that the solids are suspended in the oils. Oil crystallization is initiated in a tempering unit, and the tempered product is deposited on a moving belt which passes through a cooling tunnel to cool and crystallize the fats to produce a dried flake product. Apparatus for carrying out the method is also provided.

Title: Optical method of measuring an alternating electrical current, including temperature compensation, and a device for carrying out the method
Inventor: BOSSELMANN THOMAS
IPC: G01R15/24
Filed: 1994-03-10
Abstract: The invention concerns a method of measuring an alternating current (IA) in a conductor (2), the method calling for the plane of polarization of linearly polarized light to be rotated through a measuring angle (ALPHA) in a Faraday element (3) surrounding the conductor (2).  This light with rotated polarization is divided into two light signals (LS1, LS2) with planes of polarization at right angles to each other, and the corresponding electrical signals (S1, S2) produced by conversion in optoelectric converters (12, 22) are split into their direct signal components (D1, D2) and their alternating signal components (A1, A2).  The invention calls for the quotients5 ((A1-A2)/(Al+A2) and ((D1-D2)/(D1+D2)) of the differences and sums of the alternating signal components (A1, A2), as well as of the direct signal components (D1, D2) to be determined.  A temperature-compensated measuring signal (SA) is derived from the quotients of the direct signal components ((D1-D2)/(D1+D2)) and the quotients of the alternating signal components ((A1-A2)/(A1+A2)).

Title: Systeme d'arrosage pour le controle de la vegetation
Inventor: CARRIERE JEAN-CHARLES
IPC: A01M7/00
Filed: 1995-10-26
Abstract: Ce système d'arrosage a premièrement été inventé pour répondre à des besoins spé cifiques de la clientèle de SOLUTIONS-ENVIRONNEMENT INC. relativement au contrôle de la végétat ion. Le contrôle de la végétation consiste à éliminer certaines espèces végétales nui sibles soit par leur espèce ou par la densité localisées à environ 15 mètres de chaque côté de la voi e ferrée. Cette activité était effectuée par des moyens mécaniques, tels la coupe et le brûlage, mais ces techniques exigent l'emploi d'un grand nombre de personnes et doivent être répét ées régulièrement car elles favorisent la repousse. Notre invention porte sur la conception d'un s ystème d'arrosage hydraulique opéré par deux techniciens permettant un arrosage uniforme et sélect if des zones ciblées. Le système d'arrosage permet un arrosage sélectif de la végétation sur une large ur de 13,5 mètres de part et d'autre à partir du camion porteur. Le principe de fonctionnement du système d'arrosage pour le contrôle de la végétation est le suivant: Afin de pouvoir arroser les deux côtés simultanément le système nécessite deux o pérateurs qui sont situés sur une plate-forme surélevée placée à l'avant du système. Sur cette plate-forme, on retrouve deux postes de contrôle permettant de contrôler l'arrosage et les mouve ments des bras porteurs de chaque côtés. Les bras porteur sont actionnés à l'aide de manettes r eliées à un système hydraulique permettant une rotation sur 180.degree., une élévation verti cale de -15.degree. à +75.degree. par rapport à l'horizon. Une section interne extractible permet d'obtenir une longue ur de bras variable. Cette section est également actionnée hydrauliquement. Un tel système permet d'augmenter l'efficacité du traitement, de réduire le temp s de voie ferrée requis pour l'application du phytocide homologué, de réduire le nombre d'opérate ur requis, d'optimiser la quantité de phytocide utilisé par l'arrosage sélectif, réduire le s coûts globals du traitement, peut être utilisé sur la route, dans les champs et sur les voies fer rées avec un système Hy-rail, et permet la défoliation et la stérilisation en simultanné.

Title: Process for obtaining a signal indicating a synchronization error between a pseudo-random signal sequence from a transmitter and a reference pseudo-random signal sequence from a receiver
Inventor: WOLF ANDREAS
IPC: H04L7/04
Filed: 1994-05-06
Abstract: Process for obtaining a signal indicating a synchronization error between a pseudo-random signal sequence from a transmitter and a reference pseudo-random signal sequence from a receiver.  This invention concerns a process for obtaining a signal indicating a synchronization error between a pseudo-random signal sequence from a transmitter and a reference pseudo-random signal sequence from a receiver in a measuring device on the receiving end. In order to be able to detect a synchronization error as quickly and reliably as possible, successive sections (a, b, c) of a reference pseudo-random signal sequence (g'(n)) are each cross-correlated separately with the received pseudo-random signal sequence (g(n)), yielding partial cross-correlation functions (KKFa(n), KKFb(n) and KKFc(n)); the partial cross-correlation functions are added up to obtain a sum cross-correlation function (KKFs(n)) that is analyzed to detect the proper chronological occurrence of at least three maximums (ma, mb and mc). If the maximums (ma, mb and mc) do not occur at the proper times, a signal (synch) indicating a synchronization error is generated.
