Patent MX-PA03008362-A (MX)
Title: Linear tensioner.
Inventor: SERKH ALEXANDER
IPC: F16H7/12
Filed: 2002-02-01
Abstract: A tensioner having a base. A spring connected to the base biases a plate, having a pulley, toward a belt. Frictional blocks are aligned on the base in a staggered fashion along a spring centerline. The plate slidingly moves in a linear path between the blocks. The blocks constrain the path of the plate allowing movement in only a single axis parallel to a spring axis. A hubload from a belt running on the pulley combined with the spring force acting on the plate creates a force couple acting on the plate through the frictional blocks. The engaging surfaces between the plate and the blocks have a predetermined coefficient of friction thereby creating a damping force as the pulley and plate move in a linear path on the blocks.

Title: Juice deacidification.
Inventor: YONGSOO CHUNG
IPC: A23L2/78
Filed: 2002-09-20
Abstract: A system and process for making a low-acid, single strength juice such as a not from concentrate (NFC) citrus juice are provided in which an initial single strength juice flow can be cooled to a temperature of not greater than about 45°F and maintained at that temperature or below throughout the process (except during pasteurization). From the initial juice flow, a first portion of the juice is diverted from a second portion of the juice. Suspended solids are separated out from the first portion to provide a solids-reduced juice. The solids-reduced juice is subjected to ion-exchange deacidification. Preferably, a portion of the initial single strength juice flow is added to the deacidified juice immediately after deacidification in order to immediately lower the pH of the deacidified juice to a value that discourages microbial activity.

Title: PRODUCTION OF CHIRALLY PURE alpha-AMINO ACIDS ADN N-SULFONYL alpha-AMINO ACIDS.
Inventor: LYNN RESNICK
IPC: C07D233/66
Filed: 2002-11-26
Abstract: Methods for production of chirally pure alpha-amino acids and N-sulfonyl alpha-amino acids are described. An aldehyde and a cyanide salt are reacted with an alpha-methylbenzylamine to afford a product. The product reacts with a strong acid, is neutralized, and is extracted. The resulting product is subsequently hydrogenated and hydrolyzed to provide a product which is dissolved in a strong acid to provide a salt of a chirally pure alpha-amino acid, which is reacted to provide the chirally pure alpha-amino acid. Another method involves mixing ephedrine hemihydrate and an N-sulfonyl alpha-ethylnorvaline in ethanol at a molar ratio of 1:1; heating the mixture to dissolve the solids; cooling to allow formation of a precipitate; washing with an organic solvent to give diastereomeric salt; recrystallizing the salt; dissolving the recrystallized salt in an organic solvent and strong aqueous acid, separating the layers; washing the organic extract; drying and concentrating to provide chirally pure N-sulfonyl alpha-amino acid.

Title: Bumpless crankshaft position sensing.
Inventor: ANDREAS PETERSON
IPC: F02D41/34
Filed: 2005-05-24
Abstract: Disclosed herein are methods of generating an active crank series of signals that is derived from at least two series of signals, wherein one or both of the series of signals have been modulated to produce two series of signals that resemble each other. Also disclosed herein is a crankshaft positioning system for determining the rotational position of a crankshaft of an engine that utilizes at least two crank angle sensors 10 and 12 . The signal information from the two crank angle sensors 10 and 12 is processed by a signal processor 150 such that the series of signals 220 from the second crank angle sensor 12 emulates the series of signals 210 from the first crank angle processor 10 . The signal processor generates an active crank series of signals 230 based on the two series of signals 210, 220 . The active crank series of signals 230 is sent to an engine control processor 120 which directs the injection and/or ignition of fuel into cylinders of an engine. According to the system ex emplified herein, the active crank series of signals 230 sent to the engine control processor 120 is not disrupted despite failure of one of the crank angle sensors. These and other embodiments are disclosed.

Title: Methods and devices for determining a correction value for a measured segment time.
Inventor: ARUN NANDAGIRI
IPC: A61K8/68
Filed: 2004-03-05
Abstract: The invention relates to methods and devices for determining a correction value for a measured segment time which the shaft of an internal combustion engine, especially a crankshaft, requires for rotating about a defined angular degree. The aim of the invention is to provide a method and a device which allow for the determination of such a correction value for individual cylinders. For this purpose, the following correlation is evaluated: AZn=[(TGn-TG0)-(n/z)*(TG0'-TG0)] / [TG0+(n/z)*(TG0'-TG0)], whereby z is the number of cylinders of the internal combustion engine, n is the number of the cylinder presently observed, TGn is the measured segment time of the cylinder having the number n, TG0 is the measured segment time of a reference segment of a reference cylinder, TG0' is the segment time of the reference segment of the reference cylinder measured two crankshaft rotations after the segment time TG0, and AZn is a correction value for the segment time of the cylinder having the number n. The invention allows the determination of correction values irrespective of the availability of possible speed gradients.
