At least one frequency selective assembly (37, 24) is included, interconnected with the second port of the signal transfer module, presenting a characteristic impedance to a desired signal of the input signal and reflecting of their signals of the input signal to the second port of the frequency transfer module. A means, within the signal transfer module for transferring a reflected signal received at the second port of the signal transfer module to a third port of the signal transfer module is also included. A first antenna (31) is interconnected with the frequency selective cavity assembly for transmission of the desired signal. A second antenna (30) is interconnected with the third port of the signal transfer module for transmission of the other signals. The method of practising the invention is also provided.
Patent CA-2137191-A1 (CA)
Inventor: HINDS MARK E
IPC: G01R31/08
Filed: 1994-12-02
Abstract: An instrument and method for the troubleshooting and verification of copper-wire local area network (LAN) cable systems provides a series of resistance and capacitancemeasurements between all possible wire pairs using a pair of switch matrices and a software method for evaluating the measurements which are stored in a two-dimensional matrix. The stored measurements are evaluated against predetermined figures of merit and the decision pattern in matrix form is compared to that of a known good LAN cable system. Error messages responsive to mismatches are generated and presented to the operator via a user interface. Near-end cross talk (NEXT) isolation is evaluated using a mathematically calculated differential capacitance technique. Error messages aregenerated responsive to difference capacitance values larger than a figure of merit correlated to an acceptable level of NEXT isolation.

Title: A genetically engineered cell line for detecting infectious herpes simplex virus and method therefor
Inventor: OLIVO PAUL D
IPC: C12Q1/68
Filed: 1993-06-17
Abstract: A diagnostic assay for detecting the presence of an infectious herpes virus in a specimen and a genetically engineered cell line for use in such assay are disclosed. The cell line used in the assay expresses a reporter gene only if infectious herpes virus is present in the specimen. The assay involves inoculating a DNA-transfected cell line with a specimen suspected of containing a herpes virus, allowing a sufficient period of time for the herpes virus infectious cycle to proceed, and detecting and quantifying the number of herpes virus-infected cells to determine the number of infectious herpes virus virions in the specimen. The cell line is a DNA-transfected cell line susceptible to infection by a herpes virus which is stably transformed with a chimeric gene compris-ing a herpes virus inducible promoter and a gene coding for an enzyme, the expression of the enzyme being dependent upon and quantitatively proportional to the presence of herpes virus. A kit for such assay is also provided.
Patent CA-2138233-A1 (CA)
Title: Biodegradation process for treating organic wastewater
Inventor: KAGAWA HARUO
IPC: C02F1/52
Filed: 1994-12-15
Abstract: A low concentration (0.1 to 0.5 mM) of aluminum ions is added to an organic wastewater to selectively raise specific bacteria which can grow without producing unpleasant odors. The bacteria is used for treating the organic wastewater of high density without producing odors thus contributing to the minimum size of a wastewater treatment system. Then, increase of the aluminum ions to a high concentration (more than 4 mM) accelerates flocculation and precipitation of the bacteria for disposal. When a proper mineral is added two the wastewater, a lower concentration (more than 1 mM) of the aluminum ions can encourage the flocculation and precipitation of the bacteria and also, a resultant sludge will be reduced in amount for ease of maintenance.

Title: System for Disinfecting the Water Lines of a Dental Unit
Inventor: PREVOST ANDRE
IPC: A61C17/00
Filed: 1995-01-03
Abstract: A system for disinfecting the water lines of a dental unit is provided with first and second unidirectional check valves. Water at a first pressure is normally supplied to the water lines of the dental unit through the first check valve. A reservoir of liquid disinfectant can be pressurized at a second pressure higher than the first pressure by the air compressor already equipping the dental unit to supply disinfectant to the water lines of the dental unit through the second check valve. Liquid disinfectant is prevented from reaching the water supply line by the first check valve. In the same manner, when the reservoir is not pressurized, the second check valve prevents water from the water supply line from reaching the disinfectant. The reservoir is formed with an upper neck and a bottom, and the disinfectant system is provided with a housing on which an upper stopper fitting into the neck and a lower reservoir bottom support are mounted, whereby for mounting the reservoir on the housing, one successively tilts the reservoir, places the neck on the stopper and slides the reservoir bottom on the support, which sliding movement is facilitated by a rounded edge of the reservoir bottom.

Title: Water pistol and puppet assembly
Inventor: SPECTOR DONALD
IPC: A63H33/28
Filed: 1996-04-30
Abstract: A water-pistol and puppet assembly in which the pistol is concealed within the puppet, yet is fully operable.  The pistol includes a hand grip provided with a trigger, a liquid reservoir and a pump which when the trigger is pulled then draws liquid from the reservoir and pumps it into the barrel of the pistol from whose outlet nozzle the liquid is ejected.  The puppet includes a head having an open mouth that simulates that of a human or animal-like figure and a costume shroud simulating the body of the figure associated with the head.  The body-like costume shroud has a cavity therein which communicates with the head and with an access opening, the pistol being received within the cavity so that its barrel lies within the head and its nozzle is aligned with the open mouth. When a player extends his hand through the access opening in the shroud to grasp the grip of the pistol, he then appears to be holding the puppet.  And when he pulls the trigger, liquid is then ejected from the outlet nozzle through the open mouth so that the puppet then appears to be spitting.

Title: Knock sensor-triggered timing light with visible laser retro-reflecting control
Inventor: BECKER THOMAS P
IPC: F02P17/06
Filed: 1996-06-06
Abstract: A diesel timing light includes a flash circuit for flashing a xenon lamp in response to ignition events sensed by a knock sensor.  A trigger circuit enables the flash circuit only in the presence of an enable signal, which is generated by a sensing circuit immediately before the ignition of the no. 1 cylinder.  The sensing circuit includes a visible laser source which illuminates a patch of reflective tape on the engine flywheel just ahead of a timing mark corresponding to engine top dead center.  The tape reflects the visible laser light to a sensor which generates the enable signal.  The trigger disables the flash circuit immediately after the flash triggered by the first ignition event after the enable signal.  LED indicators indicate when the photosensor is detecting the reflected beam and when the knock sensor is detecting ignition events.
Patent CA-2179904-A1 (CA)
Inventor: SCHNEIDER REINHARD
IPC: C25D3/02
Filed: 1995-02-23
Abstract: The invention relates to a method of electrolytic deposition of metals from electrolytes, which contain additives or process organics in order to achieve specific physical properties. Such additives are subject to continuous consumption during electrolysis, decomposition products forming from these additives, which deposit in the entire electrolytic system and thus also on the material for treatment.        Thus the object underlying the invention is to avoid quality shortfalls in the deposited coatings caused by organic residues, and in this way to achieve a continuous metal deposition with uniform quality of the metal coatings. This object is achieved by spatial limitation of the concentration of the process organics to the electrolyte region in the electrolytic system in which it is relevant to the process. The circulated electrolyte is kept free of process organics by filters. Renewed metered addition of process organics is effected in dependence on consumption directly before the region relevant to the process.
