Patent CA-2174098-A1 (CA)
Title: Method of inducing and maintaining neuronal cells
Inventor: MELTON DOUGLAS A
IPC: C12N5/10
Filed: 1994-10-14
Abstract: The present invention makes available a method for inducing neuronal differentiation and preventing the death or degeneration of neuronal cells both in vitro and in vivo. The subject method stems from the unexpected finding that, contrary to traditional unterstanding of neural induction, the default fate of ectodermal tissue is neuronal rather than mesodermal and/or epidermal. In particular, it has been discovered that preventing or antagonizing a signaling pathway in a cell for a growth factor of the TGF-.beta. family can result in neuronal differentiation of that cell.

Patent CA-2188935-A1 (CA)
Inventor: VOGEL ELFRIEDE
IPC: E01H10/00
Filed: 1995-04-24
Abstract: L'invention concerne un procédé et un dispositif de déglaçage automatique de voies de circulation (1) sur lesquelles est appliquée une solution aqueuse d'agent de dégivrage dans le but d'abaisser le point de congélation. Cette solution s'écoule de la voie de circulation sous forme d'eau de dégivrage, éventuellement mélangée avec des eaux de précipitation et de fonte des neiges, qui est recueillie, et qui, après mesure de sa concentration en agent de dégivrage (en 18), est réappliquée (par l'intermédiaire de 11), au moins partiellement, et, si nécessaire, après addition d'agent de dégivrage frais, sur la route, en tant que solution aqueuse de dégivrage. Le procédé et le dispositif proposés sont particulièrement économiques, étant donné qu'avant la réapplication, en tant que solution de dégivrage de l'eau de dégivrage devant être réutilisée, sa concentration en agent de dégivrage est augmentée (en 26) dans un étage de séparation dans lequel des flux partiels sont produits qui sont constitués, respectivement, d'eau contenant peu ou pas d'agent de dégivrage (en 31) et de solution très concentrée (en 32), cela permettant de réutiliser une plus grande proportion d'eau de dégivrage. Des étapes destinées à éliminer des substances nuisibles peuvent être également incorporées à ce cycle.

Title: Integrated circuit leadframe with reduced inductance pin connections
Inventor: HARRIS COLIN CAMPBELL
IPC: H01L23/495
Filed: 1996-11-06
Abstract: An integrated circuit  leadframe having a die attach paddle which is perforated at each wire down bond site.  The plastic molding compound used to encapsulate the IC  flows  through  the  perforation(s).    The  solidified molding compound extends through the die attach paddle to resist potential delamination and consequential breakage of the down bond.  The die attach paddle's surface may alternatively be dimpled, serrated, or otherwise roughened to improve adhesion of the molding compound at each down bond site and thereby resist delamination of the molding compound at  such sites.   As a further alternative,  each leadframe  lead selected for use as a power or ground connection may be directly connected to the die attach paddle,  and a wire bonded from each such lead to the integrated circuit  in order to  form a  low  inductance electrical connection between the integrated circuit and each power or ground lead.

Title: Travelling log for intelligent network testing
Inventor: MOHARRAM OMAYMA EL-SAYED
IPC: H04Q3/00
Filed: 1995-10-19
Abstract: In an Intelligent Network (IN) (10) a testing capability is provided at a service switching point (SSP) (12). The testing capability comprises a test call (34) initiated from the SSP to a desired destination (14) within the network. The testing capability uses the Common Channel Signaling Number 7 (CCS7) network protocol. It uses the CCS7 TCAP (Transaction Capability Control Park) for IN queries packages (50) and the CCS7 ISDN User Part (ISUP) (40) for call set up messages. The testing capability defines a portion on the (TCAP) and (ISUP) to log (TLog) the network devices transversed in the IN call. The test call with the log portion appended to TCAP (and ISUP) messages travels through the network and collects data (208, 210) in the log portion from each node on the test call path. The test call with the travelling log (TLog) helps the maintenance personnel isolate troubles and faults in the network without having to monitor each node (or office) on the route of a troubled message path.

IPC: F28F9/22
Filed: 1995-09-26
Abstract: The invention relates to a liquid distributor in a evaporator, intended in particular for the evaporation treatment of liquid suspensions which contain fibers or other such solid ingredients. The distributor comprises, located at the upper end of the heat exchange surface, a transverse frame (1), liquid conduits (3, 4) disposed therein distributing the liquid over the entire width of the surface. According to the invention the liquid conduits are made up of feed conduits (3) slanted obliquely downwards and of distrribution conduits (4) branching out therefrom and leading to the heat exchange surface, at the branching points (7) of which conduits their wall surfaces on the downstream side with respect to the feed flow (8) are rounded into curved dividing surfaces (10) by means of which the dividing of the flow is carried out. Respectively the branching points (7) on the upstream side with respect to the feed flow (8) are equipped with sharp feeding tips (11) in such a manner that the flow will travel in the feed conduit (3) in a cascade-like manner over the feeding tips to the dividing surfaces, which will cause a division of the flow substantially equally among the distribution conduits.

Patent CA-2207020-A1 (CA)
Inventor: FUNG CLIFFORD D
IPC: G01L9/00
Filed: 1995-12-15
Abstract: The object of this invention is to eliminate long-term transient behavior upon electrical excitation of polycrystalline silicon and provide electrical excitation with a minimal stabilization period and utilizing micro-power consumption. This invention comprises an electronic excitation circuit for a polycrystalline silicon sensor that detects the pressure of a process flow.  The sensor consists of polycrystalline silicon piezoresistors (22) deposited onto a polycrystalline silicon sensing diaphragm (14) having a dielectric layer (18) interposed in between. Electrical excitation of the piezoresistors is accomplished by an alternating electrical waveform having a constant amplitude of less than 10 volts and at a frequency of less than 100k Hz. The waveform is applied to a first input terminal (40a) of a Wheatstone bridge with an opposite polarity to a second input terminal (40b) of the bridge. The resultant voltage difference between the output terminals is used to detect an imbalance in the electrical resistors induced by applied pressure. The voltage level and frequency range chosen is such that the circuit utilized approximately 1 mW of power.

Title: A polytetrafluoroethylene catalyst retaining apparatus and method of making and using same
Inventor: SASSA ROBERT L
IPC: B01J31/06
Filed: 1996-04-19
Abstract: The present invention is an improved apparatus and method for using a catalyst to remove contaminants from a fluid stream. Catalytic particles are enmeshed within a highly porous expanded polytetrafluoroethylene (PTFE) substrate. The use of an expanded PTFE substrate provides added strength to the substrate and provides open and uniform porosity, thus, assuring proper exchange of molecules between the exterior surface of the substrate and the catalytic particles held within it. As such, the present invention is particularly suitable for use as a cross-flow filter for use in ozone generating office equipment (e.g., an electro-static photocopy machine) or similar application requiring minimal pressure drop across the filter unit.
