Patent CA-2129893-A1 (CA)
Inventor: EDELEN STEPHEN A
IPC: B60W10/11
Filed: 1994-08-10
Abstract: The shift quality of an automated mechanical transmission (10) is improved and transmission wear is reduced by controlling the armature current of the motor driving the transmission shifting mechanism (22). The current is monitored by a microcontroller (16) to determine if the shifting mechanism has encountered a snag or has stalled during a shift operation. The microcontroller (16) is programmed to control the duty cycle of a pulse width modulated (PWM) voltage signal, applied to the motor, in accordance with an algorithm which provides both proportional and derivative control of the error between the measured current and a target current. The rapid reduction in current spikes through PWM control reduces the force applied to the shifting mechanism (22) and thus the sliding clutch and transmission gearing. <IMAGE>

Abstract: A method of partitioning a pre-selected phase of a sample of liquid having a plurality of phases of differing densities, a separation device and a tube containing the separation device. The sample of liquid is placed in a first chamber of a linear tube that is separated from a second chamber by a separation device. The separation device slidably engages the interior surface of the tube in an essentially fluid-tight manner and has an axial orifice on the longitudinal axis of the tube that is in fluid flow communication with a flow-restriction channel. The phases are ordered concentrically by rotating the tube around its longitudinal axis e.g.  in an axial centrifuge. The volume of the first chamber is reduce by movement of the separation device within the tube, that phase of the liquid located axially within the first chamber flowing into the axial orifice and passing through the flow-restriction channel into the second chamber. The reduction of the volume of the first chamber is controlled using phase-separation information.  The method is useful in separation of blood components.

Title: Preparation Process of a Natural Protein Sweetener
Inventor: URIACH-MARSAL JUAN
IPC: A23L27/10
Filed: 1995-04-21
Abstract: Thaumatin II or thaumatin I can be obtained through the expression, not of their natural genes, but of artificial, synthetic and substantially optimized genes following specific rules.  Preferably, this expression is carried cut in filamentous fungi, especially GRAS fungi and particularly the species Penicillium roquefortii, Aspergillus niger and the awamori variant of Aspergillus niger.  Preparing substantially optimized artificial genes for filamentous fungi, performed here for the first time in the case of thaumatin, allows for high protein expression, making the process useful for industrial production of this valuable sweetener.  Thaumatins may be obtained extracellularly by using a plasmid with a secretion signal, and also intracellularly.  The latter method can be used in animal feed without prior separation from the fungal mycelium.
