Abstract: A reciprocating tool post assembly is disclosed that may provide substantially linear excursions of a cutting tool mounted therein. The apparatus includes a voice coil assembly having a longitudinal axis that provides for the reciprocating movement of the assembly and to which a pair of coil arms is attached. The assembly also includes a pair of lever arms, each being pivotally attached between a respective coil arm and a draw bar, with a pair of fulcrum members attached to a base of the assembly that engage each respective lever arm to provide a fulcrum about which each respective lever arm may pivot. One end of the draw bar is attached to a tool support that is guided in a substantially axial movement by a guide member, such that, when a cutting tool is attached to the tool support the movement of the voice coil causes the cutting tool to reciprocate substantially axially with respect to the base.

Abstract: L'invention concerne des procédés qui permettent de préparer des dispositifs comportant des microcanaux (20) métalliques creux à la surface d'un substrat plan (10). Plus spécifiquement, elle concerne des procédés qui permettent de préparer des dispositifs comportant des microcanaux métalliques superficiels pour lesquels les plages de largeur et de hauteur sont sélectionnées de façon à donner un régime d'écoulement efficient, et ayant des parois de canaux épaisses et donc résistantes et durables. Ces procédés sont compatibles avec les techniques standards de fabrication de circuits imprimés et, du fait que les microcanaux (20) sont formés à la surface du substrat (10) sans entraîner de dégradation de la planéité de surface, ils peuvent être utilisés pour placer un circuit électronique dans les dispositifs contenant les microcanaux. Dans cette application, le terme de "microcanal" désigne des canaux fermés ou partiellement fermés dont la hauteur est comprise entre 2 et 200 micromètres environ (µm) et la largeur entre 10 micromètres et 2 millimètres environ.

Patent CA-2269136-A1 (CA)
Title: Circuit board mounting system and releasable connector therefor
Inventor: BROOK JOHN E
IPC: H01R12/72
Filed: 1999-04-16
Abstract: A modular mounting system which allows a circuit board to be removed, inserted or replaced through the front of the mounting frame without deactivating power to the equipment, and in the preferred embodiment without detaching any external cables. Connections for external equipment are disposed along the rear edge of the circuit board, and a row of contacts for the internal connections is provided along the bottom edge of the circuit board. The system of the invention provides a releasable connector which retracts the connector pins into a housing when a circuit board is inserted or removed, thus eliminating the possibility of a contact on the circuit board touching a live connector pin. In the preferred embodiment the external connections are made through adaptors that plug into external cable connectors provided on a connector plate detachably affixed to the rear of the mounting frame. In the preferred embodiment the invention provides an actuating mechanism for the releasable connector which must be actuated in order to remove a circuit board, thus ensuring that the connector pins have disengaged from the circuit board contacts before a circuit board is moved. The mounting system of the invention achieves a high packaging density for mounted devices and accommodates any input/output format. The invention also permits use of two or more separate circuit boards for a device residing in the same compartment and connected by an interface, which allows circuit boards to be repaired or upgraded by replacing a portion of the device circuitry. The invention also provides a novel system for cooling the mounting frame, providing heat sink tunnels in the impeller airstream and affixing the most significant heat-generating components to the heat sink tunnels. The impeller draws an intake airstream through a low resistance path within the mounting frame to cool the circuit board components.

Inventor: VAN TOEVER J WAYNE
IPC: B01J19/30
Filed: 1999-09-10
Abstract: Disclosed is a bioreactor apparatus having a bed of buoyant media pellets floating within a filtrate to be processed. The apparatus includes a tank having a peripheral wall for containing filtrate and a bed of media pellets. A central manifold is rotatably supported within the tank, the central manifold being mounted for rotation about a vertical axis and having a plurality of longitudinally spaced openings intermediate its ends, the openings adapted to eject filtrate in a generally horizontal direction and along a substantially vertical plane toward the wall of the tank, cyclically fluidize pellets in a directly narrow zone. In a preferred aspect, there is also a thrust manifold, generally parallel to the axis of the central manifold and having a plurality of longitudinally spaced openings intermediate its ends directed horizontally and generally perpendicularly to the plane. The thrust manifold is supported in association with the central manifold inwardly adjacent the tank wall and offset rearwardly of the plane to rotate with the central manifold. Filtrate is fed to the central manifold and the thrust manifold, whereby the plane of filtrate ejected by the central manifold fluidizes a vertical zone of pellet media around and in front of the thrust manifold and rotation of the central manifold and thrust manifold is caused by filtrate ejected from the openings in the thrust manifold. The invention also comprehends specially designed pellet media for optimum performance. The manifolds may be structured for retrofitting in existing bioreactors.

Inventor: BODENSTEINER RICHARD
IPC: C25F5/00
Filed: 1998-03-17
Abstract: A process for the delacquering and detinning of a metal substrate is presented comprising the fully electrochemical removal of both an outer polymeric coating and an inner thin coating from a metal substrate. The disclosed method provides a clean metal substrate, and results in wastes which are easily disposed of with minimal cost and minimal environmental impact. In one embodiment, the present invention comprises a one-stage process for removing an outer polymeric coating and an inner tin coating from a metal substrate in a single electrolyte bath through electrolytic removal of both the polymeric and tin layers from the metal substrate. An electrically conductive container having the electrolyte bath therein acts as an anode in the process, and the removed tin is plated out on the cathode. In another embodiment, the present invention comprises a two-stage process for removing an outer polymeric coating and an inner tin coating from a metal substrate. The first stage comprises removal of the polymeric coating in a first electrolyte bath through application of a cathodic current to a first electrically conductive container, e.g. tank, drum, or the like. The polymeric and tin coated metal substrate that is immersed in the first electrolyte bath is cathodically protected provided the coated metal substrate is in contact with the first electrically conductive container. The second stage comprises removal of the tin coating via application of moderate anodic currents to a second electrically conductive container, e.g. tank, drum, or the like. Such current results in the selective removal of tin from the substrate metal. The second electrically conductive container and the tin cans act as an anode in the process, and the removed tin is plated out on the cathode.
