Abstract: The present invention is directed to carboxylic acid and ester moieties that are attached to a carbon chain that is between 2 and 24 carbons in length wherein, the chain contains at least one dioxanone ring system, said dioxanone being formed from two adjacent carbons in the chain and/or at least one carbon in the chain is substituted with a pendant dioxanone ring system. In preferred embodiments, the carbon chain is a fatty acid residue. The carbons of said chain can be optionally substituted, saturated or unsaturated. When two or more said ester moieties are present, the invention is directed to a polyester such as a triglyceride, that contains multiple carbon chains wherein each chain is independently derivatized such that the triglyceride contains at least one dioxanone ring system, said dioxanone being formed from two adjacent carbons in at least one of said chains. The present invention is also directed to a method of preparing a dioxanone containing composition or fatty acid derivative.

Abstract: The present invention provides a process for extracting sterols from a high solids, thermochemically hydrolyzed corn fiber using ethanol as the extractant. The process includes obtaining a corn fiber slurry having a moisture content from about 20 weight percent to about 50 weight percent solids (high solids content), thermochemically processing the corn fiber slurry having high solids content of 20 to 50% to produce a hydrolyzed corn fiber slurry, dewatering the hydrolyzed corn fiber slurry to achieve a residual corn fiber having a moisture content from about 30 to 80 weight percent solids, washing the residual corn fiber, dewatering the washed, hydrolyzed corn fiber slurry to achieve a residual corn fiber having a moisture content from about 30 to 80 weight percent solids, and extracting the residual corn fiber with ethanol and separating at least one sterol.

Abstract: Methods for cell-free production of glucosamine from starch, maltodextrin or glycogen or from fructose and a source of amino groups are disclosed. Also disclosed are cellular extracts comprising glucosamine-6-phosphate synthase activity, as well as a cellular extract comprising glucosamine-6-phosphate deaminase.

Abstract: The invention relates to a bearing cover (1) for a crankshaft bearing of an internal combustion engine comprising a bearing shell (2), two screw columns (3,3′), which are located on both sides of the bearing shell (2) and provided for mounting on a bearing block, and comprising a reinforcement (4) of the bearing shell (2) extending between both screw columns (3,3′). The aim of the invention is to optimize a bearing cover (1) of the aforementioned type with regard to its shape whereby attaining a high level of stability with a low weight. To this end, the reinforcement (4) is comprised of two braces (6,6′), which extend diagonally from the area of the upper ends (5,5′) of the screw columns (3,3′) to the bearing shell (2) and which have an essentially constant cross-section over the length thereof, and comprised of a rib (7) extending on the upper side of the bearing shell (2) from one brace (6) to the other (6′).

Abstract: Liquid lysine can be made with almost any particular specification that may be reasonably expected. A multistep process for producing lysine includes at least: fermentation, ultrafiltration, evaporation, and mixing. Depending upon the particular specifications that are to be met, at least two liquids may be taken from selected points in the multistep process. The lysine in these two liquids is concentrated to a desired level and then the liquids are mixed together and returned to the processing feed stream. The process may be applied to any amino acid which can be produced by fermentation.

Abstract: An arrangement and method for protecting a multiple voltage supply system against voltage arc-over between the different voltage planes. For this, the voltage in the low-voltage plane of the supply system is clamped to the low-voltage value with a voltage limiter until a battery disconnect switch in the high-voltage plane of the supply system is opened and the generator output voltage in the high-voltage plane is adjusted back to the voltage value of the low-voltage plane. As a result, the high-voltage plane of the supply system is disconnected from the high-voltage sources. Consequently, the voltage in the low-voltage plane is prevented from increasing even in case of a short-circuit between both voltage planes of the supply system and the consumers in the low-voltage plane can continue to be operated safely.

Abstract: A process for improving the solubility of hydrophobic amino acids in which hot saturated aqueous solutions of at least two different amino acids are first combined. A first step includes making a hot saturated aqueous solution of a first and hydrophobic amino acid having a low solubility in water. A second step includes making a hot saturated aqueous solution of a second and hydrophilic amino acid having a high solubility in water. Then the two hot saturated aqueous solutions are mixed to prepare a combined hot solution mixture, and dried. The resulting product is an amino acid food supplement which is blended into animal feed. The preferred amino acids are tryptophan and lysine, when the animal is a domestic farm animal. A preferred ratio is where the concentration of tryptophan is greater than 50 grams per liter and the concentration of lysine is greater than 300 grams per liter.

Abstract: A motor vehicle electrical system has an electrical machine with an on-board power supply generator function. The electrical machine can be operated, in a first mode, as an on-board power supply generator, having a regulator for setting the excitation current for the electrical machine, and having an electrical load having a comparatively high power consumption, for example a heating device for an exhaust gas catalytic converter. A changeover switch, by means of which an output of the electrical machine can optionally be connected to an on-board power supply cable or to the load, as well as a control unit for controlling the regulator and changeover switch optionally in the first mode or a second mode, is provided so that the electrical machine is connected to the on-board power supply and the regulator regulates the operating voltage at an on-board power supply voltage. Alternatively, the electrical machine is connected to the load and the regulator regulates the operating voltage at a higher nominal value.
