Patent CA-2175639-A1 (CA)
Inventor: WETZEL GUSTAV
IPC: G08C19/02
Filed: 1996-05-02
Abstract: A transmitting station  (1)  is  connected  to  a  receiving station  (2)  by  a  two-wire  line (3) via which the supply current (IV) required for operating the transmitting station (1)  is  transferred  from  the receiving station (2) to the transmitting  station  (1).  The  transmitting  station  (1) comprises   a   supply  circuit  (13)  including  a  voltage regulator  (16) for maintaining the operating voltage of the transmitting station (1) constant and an energy  store  (17) for  compensating  current  and/or voltage fluctuations. Via the two-wire line (3) an analog signal current (IS) variable between two limit values is  further  transferred  from  the transmitting  station (1) to the receiving station (2), this signal current consisting of the supply current (IV) for the transmitting station (1) and a  supplementary  current  (IE) determined  by the transmitting station (1). For transfer of the   communication  information  between  the  transmitting station (1) and the receiving station  (2) by  means  of  a symmetrical  communication  current (IK) superimposed on the signal current  (IS),  the  communication  current  (IK)  is superimposed on the current flowing from the  two-wire  line (3) into the supply circuit (13).

Abstract: A method for the expression of multiple proteins in a transgenic plant comprising inserting into the genome of the plant a gene construct comprising a 5' -region which includes a promoter which is capable of initiating transcription of a structural gene under the control thereof, a protein encoding sequence coding for more than one protein and a 3 ' -terminator region which includes a polyadenylation signal, each of the said protein encoding sequences being separated from an adjacent protein encoding sequence by a DNA sequence which on translation provides a cleavage site whereby the expressed polyprotein is post-transitionally processed into the component protein molecules. The DNA sequence which encodes the post-translation cleavage site may be derived from a virus, particularly a picornavirus. In a preferred embodiment the DNA sequence providing the cleavage site encodes the amino acid sequence NFDLlkLAGDVESNPGPFF.

Title: Liquid dispenser with trigger sprayer
Inventor: FOSTER DONALD D
IPC: B05B11/00
Filed: 1996-09-05
Abstract: A liquid dispenser comprising a dispenser body, a check valve, a pressure regulating valve, and a pump piston.  The dispenser body has a generally cylindric inner surface defining at least part of a pump chamber, an intake port for fluid communication with a source of liquid, an intake liquid flow path providing fluid communication between the intake port and pump chamber, a discharge port, and a discharge liquid flow path providing fluid communication between the pump chamber and discharge port.  The check valve checks fluid flow from the pump chamber to the intake port.  The pump piston has a head at its inner end reciprocally slidable within and in sealing engagement with the pump chamber between first and second positions.  A vent passageway is defined at least in part by both the dispenser body and pump piston for venting air from the fluid receiving cavity.  The dispenser body and pump piston are shaped and configured for opening the vent passageway when the pump piston is in its second position and for blocking the vent passageway when the pump piston is in its first position. When air is in the fluid receiving cavity, movement of the pump piston from its first position to its second position opens the vent passageway to permit air to vent therethrough and prime the pump.

Patent CA-2189840-A1 (CA)
Inventor: LING SHOU-HUNG
IPC: G09B9/12
Filed: 1996-11-07
Abstract: This invention relates to parallel mechanisms and, to be more specific, mechanical devices consisting of plates connected together by several legs. The 6 degrees of freedom variable leverage motion simulator, basically an in-parallel actuated robotic platform with three serial sub-chains can provide six degrees of freedom motion capability. Two simplified versions can provide selective three degrees of freedom motion. The designs also exploit the use of various pickup points which make them very easy to adapt to different actuators and to provide different leverages. Potential energy storage devices at the pickup points act as a safety feature and reduce the payload of actuators. The arrangement may be used, among other things, as a motion/force simulator for flight simulation, driving simulation or object interaction and telepresence issues in virtual reality environments.

Patent CA-2197822-A1 (CA)
Inventor: SUTHERLAND STEPHEN B
IPC: G06T15/00
Filed: 1997-02-18
Abstract: The present method renders scan lines of an image to an output device in a memory efficient manner and in a manner suitable for a client server application using an Internet or Intranet type network.  The image is defined by a number of order objects, each of which is independently stored.  The procedure determines on a scan line basis the objects which influence the particular scan line and accumulates the rendering effect of the objects necessary for returning the scan line.  Returned scan lines are transmitted over a network to a client computer and the procedure is repeated.  Objects are only partially rendered as required to pass on the necessary information as input for the next object.  This approach maintains the independence of the objects, allows interaction of objects, allows output to high resolution output devices in a memory efficient manner, and allows each object to be reproduced at the best resolution and in an efficient manner for a large scale network application.

The syngenes are used, for example, in gene therapy to supply, via expression of their encoded proteins, a therapeutic product. In another aspect, the invention relates to protein or peptide products of syngenes and their therapeutic and diagnsotic uses.
Patent CA-2198305-A1 (CA)
Inventor: DEGANI YINON
IPC: H01L21/56
Filed: 1997-02-24
Abstract: A technique for enabling sufficient flow of flux cleaning fluids and an underfill material in the relatively low-profile gap between a flip-chip bonded IC chip and a substrate, such as a printed circuit board, is to provide at least one aperture in the substrate under the IC chip. The use of such an aperture enables, for example, flux cleaning fluid to flow through the aperture into the low-profile gap between the IC chip and the substrate surface, such as by the application of pressure or by gravity, which then exits through openings between formed interconnect bonds at a sufficient flow rate to adequately remove flux residues. An epoxy underfill to the IC chip can be formed in a similar manner. For example, a relatively thick bead of epoxy, such as on the order of the thickness of the IC chip, is deposited or stencil printed on the substrate surface around the edges of the IC chip and capillary action is then relied upon to draw the epoxy into the low-profile gap. Undesirable air pockets which otherwise would develop form the displaced air as the epoxy flows into the low-profile gap can advantageously escape through the aperture of the invention.
Patent CA-2209116-A1 (CA)
Inventor: BOURGEOIS STEPHANE
IPC: G01G19/00
Filed: 1997-06-27
Abstract: The  precipitation  measuring  system  is  used  for electronically measuring the amounts of rain, snow, hail or the like, with the use of a load cell. The system comprises a second frame mounted within a first frame.  The second frame bears the collector and a load cell connects the second frame to the first frame. The load cell comprises a strain  gauge  bridge  which  is  used  to  convert  strain variations  in  the  load cell  into electrical  conditions altering an electric current. These electrical variations correspond to weight variations occurring when the amount of precipitations in the collector varies and are then recorded by a recording device such as a computer. One advantage of the  present  invention  is  that  the  static  and  dynamic friction  are  eliminated,  which  greatly  improves  the precision  and  reliability of  the  system over  the  ones presently in operation. The calibration procedures are also simplified.
