Title: A hybrid method for the coating of a substrate by a thermal application of the coating
Inventor: SCHMID RICHARD K
IPC: C23C4/12
Filed: 2004-03-08
Granted: 2012-02-14
Abstract: In the method for the coating of a substrate (3), a hybrid coating method is carried out with a thermal process jet (2) which makes it possible to combine the properties of a thermal spray method with those of a reactive vapour phase deposition. The properties of the process jet are determined by controllable process parameters, in particular by the parameters of pressure, enthalpy, composition of a process gas mixture (G) and composition and form of application of a coating material (M). The coating material is partly or completely evaporated in dependence on the controllable parameters. The phases of the coating material present in vapour form (23b) and, optionally, in condensed, i.e. solid or liquid form, (23a) are at least partly deposited on the substrate. The relative proportion of vapour and/or of condensed phase for the coating material (23) transported in the process jet is determined by a diagnostic measuring method (D). The controllable process parameters are set with respect to desired values using such gained measured data (65). A regulation (C) for the direct manufacture of the coating, in particular of a multi-layer coating system (4), is carried out with respect to these desired values, which correspond to a pre-determined vapour proportion or to a proportion of a condensed phase.

Abstract: An optical switching fabric enables an optical signal entering the device on any one of multiple input ports to be directed to any one of multiple output ports. The present optical switching fabrics include sensing and monitoring devices that permit precise initial calibration and continuous switch connection status monitoring and control. Light entering the switching fabric on an input port is reflected by one of a first set of individually controllable mirrors to one of a second set of individually controllable mirrors and then to a corresponding output port. The switching fabrics include control lasers and position sensing devices which provide output signals corresponding to the orientations of the mirrors. In addition, a subset of the input ports and output ports can be attached to monitor light sources and detectors for recalibration and control. Further, sensors for detecting the intensity of input signals, of signals that have been reflected by a mirror in the first set and by a mirror in the second set, and of signals backscattered from the output ports may be included.

Abstract: Selon l'invention, des circuits de distribution de courant électrique pour des véhicules à moteur comprennent un élément de commutation permettant de commander l'alimentation desdits circuits. Des éléments de dosage de courant associés à chaque élément de commutation indiquent la quantité de courant prélevé par les circuits électriques respectifs. Un microcontrôleur (48) permet d'obtenir un signal d'activation pour les éléments de commutation, souvent en accord avec un rapport cyclique à modulation de largeur d'impulsion. Ledit microcontrôleur (48) met en oeuvre un algorithme de protection de circuit qui prend comme entrées les indications de courant prélevé par un circuit électrique particulier et le rapport cyclique. Un courant continu équivalent est estimé, permettant de déterminer un indice de chaleur pour un hypothétique fusible apte à protéger le circuit. Lorsque l'indice de chaleur dépasse la limite du fusible, celui-ci fond.

Abstract: According to a first aspect there is a method for producing a protein-free product comprising free amino acids and short peptides, wherein raw protein materials are crushed and hydrolysed with endogenous enzymes and passed through different separation processes, including coagulation of protein residues, in order to obtain the desired product. The invention further comprises the product obtained and uses thereof. According to a second aspect, a protein product enriched with free amino acids and short peptides is produced, wherein the raw protein materials are ground and hydrolysed with endogenous enzymes, and wherein the hydrolysate undergoes various separation processes. The product obtained comprises proteins, short and long peptides, free amino acids and minerals and has a low fat content and salt content.  According to a third aspect, hydrolysation of a protein-containing raw material and separation of amino acids/peptides is carried out, wherein the hydrolysation is effected by using the endogenous enzymes of the protein-containing raw material. The hydrolysate is passed through a membrane filter, wherein peptide/amino acids follow a permeate stream, whilst the active enzymes continuously break down any protein residues that are deposited on the membrane surface.

Abstract: The present invention is directed towards an optical receiver including an open loop automatic gain control (AGC) circuit. Optical signals received by the optical receiver are converted to electrical signals via a photodiode. The electrical signals are subsequently amplified through an input and an output amplifier stage. The amplified signal is then converted to RF signals and provided to an output port for further transmission. Concurrently, the AGC  circuit senses the input optical power level at the input photodiode. The input optical power level is compared with a reference voltage, thereby providing a difference voltage. The difference voltage is applied to input and output amplifier stages for correcting the electrical signals to ensure a constant output power level.
