Patent CA-2225829-A1 (CA)
Inventor: BARON DAVID T
IPC: B05B1/34
Filed: 1996-07-05
Abstract: L'invention se rapporte à un procédé de traitement chimique et électrolytique et de lavage de plaquettes et de feuilles à circuits imprimés, pouvant être appliqué avec une précision et une vitesse élevées, en utilisant un liquide de traitement à travers lequel les plaquettes et les feuilles à circuits imprimés sont transportées en position horizontale et suivant un sens d'acheminement horizontal. L'invention concerne également un dispositif pour la mise en oeuvre de ce procédé. Pour l'accélération de ces processus, les surfaces des produits à traiter doivent être exposées à un macro-courant permettant l'approche d'un liquide de traitement actif. De plus, le micro-échange de matière doit être accéléré vers l'intérieur de la couche de diffusion. A cet effet, on utilise des générateurs de cavitation à effet hydrodynamique, produisant des bulles de cavitation se formant dans les jets de liquide (50), on accélère le liquide de traitement sous haute pression à la sortie du générateur et on imprime un mouvement tourbillonnaire au liquide de traitement dans les générateurs. Le liquide de traitement est refoulé sous haute pression dans le circuit, à travers des buses produisant des bulles de cavitation (10), et envoyé en grandes quantités sur les surfaces. Les bulles de cavitation contenues dans le liquide implosent sur la couche de diffusion, provoquant ainsi le micro-échange de matière. L'application du procédé est particulièrement efficace pour la réalisation d'alésages de précision et de trous borgnes lors de l'usinage de plaquettes à circuits imprimés.

Title: Method and apparatus for grinding composite workpieces
Inventor: CLEWES STUART
IPC: G05B19/416
Filed: 1997-04-22
Abstract: A method is described for grinding a composite workpiece (18) to form a component having concentric (31) and eccentric cylindrical regions (30). The method comprises mounting the workpiece (18) in a computer controlled grinding machine (10) having a grinding wheel (12) the advance and withdrawal of which is controllable by a programme entered into the controlling computer (32), loading a wheelfeed controlling programme into the computer, relatively positioning the grinding wheel and the workpiece to align the wheel with a first selected region of the workpiece, advancing the grinding wheel towards the selected region so as to grind the surface thereof, controlling the wheelfeed so as to maintain grinding contact between the grinding wheel and the workpiece so as either to grind a concentric cylindrical region thereon or an eccentric (offset) cylindrical region thereon as required, information about each selected region of the workpiece being stored in the computer and addressed as appropriate so that the wheelfeed can be cotrolled appropriately depending on whether a selected workpiece region is to be ground as a concentric or an eccentric (offset) cylindrical region. The method allows a workpiece having both concentric and eccentric (offset) cylindrical regions thereon to be ground using a single grinding machine under computer control without demounting the workpiece from the machine. The method also envisages introducing small advance and retract movements in the wheelfeed whilst the grinding wheel is engaged in grinding a concentric cylindrical workpiece region so as to introduce into the ground region an eccentricity which is equal and opposite to any eccentricity which grinding process forces introduce into the ground region, so that the two eccentricities cancel out. A computer controlled grinding machine is described as are programmes for  controlling the machine.

Inventor: FEY MARGARET H
IPC: D06F39/06
Filed: 1998-10-30
Abstract: A washing machine for automatically laundering articles of clothing by imparting mechanical actions upon the articles of clothing within a basket of the machine during a washing operation that includes a wash cycle and a preset number of rinse cycles incorporates a control system that functions to alter the mechanical actions imparted upon the articles of clothing during at least the wash cycle, and preferably both the wash cycle and at least one of the rinse cycles, and/or adds a supplemental rinse cycle to the overall washing operation in response to an indication of a high suds level condition in the machine. The control system receives signals indicative of an operating parameter of the washing machine, such as the input torque or operating speed of a motor of the machine, from a detection unit and utilizes these signals to determine the presence of high levels of suds and the need to transfer to a suds reduction mode of operation. In at least a preferred embodiment of the invention, provisions are made to recover from the suds reduction mode by returning to the normal washing operation and/or simply cancel the supplemental rinse cycle.
