Patent CA-2122822-C (CA)
Title: Induction furnace
Inventor: ARVEDI GIOVANNI
IPC: F27D99/00
Filed: 1992-12-17
Granted: 2001-08-28
Abstract: An improved induc-tion furnace is described which is capable to continu-ously and homogeneously heat a flat product of steel industry, particularly a thin slab from a continouous casting plant, upstream of the final rolling steps during the manufacture of thin steel strips. Owing to the small thickness shown by the pro-duct to be heated a furnace of this type will have a re-duced size of coils in the strip feeding direction. To avoid that under these condi-tions the efficiency may de-crease and a great leakage flux may be established, with consequent serious draw-backs, the present invention provides for a flux concen-trator formed of two continu-ous packets of lamination having a substantially C-shaped cross section wrapping the inductor coil both at the upper and lower side along the whole length thereof while leaving free only the passage area through which the product to be heated enters the coil.

Abstract: An assembly for storing and displaying discs, cassettes, game cartridges, tapes and/or the like, including an elongated, straight side-walled storage unit forming one or more vertically upright columns of longitudinally-spaced storage slots. First and second side members are secured to the opposite lower sides of the storage unit and extend out from them. A top member is secured to the storage unit and extends up from it.      The side members and top member are configured such that they together with the storage unit define in front view a readily-recognizable outline of a common (non-storage unit) object, such as a guitar or other musical instrument. The slots or ribs of the storage unit define, when the object is a stringed musical instrument, the frets thereof. An interesting, attractive and readily-identifiable storage and display assembly is thereby defined. The side and/or top members can also provide surfaces to which holders for holding special tapes or cases are face mounted. The entire assembly can be mounted flat against a wall or upright to a base.      When mounted to a base, the side members themselves can be directly secured to the base to further brace and support the elongated storage unit upright on the base.      Alternatively, another similar storage unit can be mounted back-to-back to the storage unit, both mounted to a rotatable base and the top member used as a turning member for turning the units on the base.

Patent CA-2141390-C (CA)
Inventor: VERHAART HENRICUS FERDINANDUS
IPC: G01R27/20
Filed: 1995-01-30
Granted: 2002-10-01
Abstract: The invention relates to a method for measuring a resistance value in a network incorporated in an electri-cal apparatus, wherein the network has at least two accessible terminals, the network has at least two time constants differing mutually by at least one order of magnitude, and the resistance value can be related to the voltage applied to the terminal clips and the current flowing through the apparatus.      Such control switches are poorly accessible.   Direct measurement is time-consuming as a result of the large value of the time constants. These problems are diminished by applying a step-like change of the voltage to the terminal clips, measuring the current flowing through the terminal clips before the change has taken place and after the transient phenomenon related to the smallest time constant and caused by applying the change is damped, and calculating the first resistance value from the measured values of the current.

Abstract: A comb splitting system demultiplexes and/or multiplexes a plurality of optical signal channels at various wavelengths. The comb splitting system has at least two interconnected successive stages of wavelength division multiplexers (WDMs). A WDM of a first stage communicates bands of channels to respective WDMs of the second stage via suitable optical paths. Each of the bands has a plurality of the individual channels that are separated by at least one other of the channels. Each second stage WDM, which is allocated to a particular band, is interconnected to optical paths, each for carrying one or more individual channels. Furthermore, in accordance with a significant feature of the present invention, the bandpasses and bandpass periodicity (free spectral range)associated with the first stage WDM are smaller than the bandpasses and bandpassperiodicity associated with the second stage WDMs. The foregoing feature has numerous advantages. The second stage WDMs are less expensive and physically smaller than the first stage WDM. Crosstalk between channels is reduced. The alignment of the WDM passbands with the wavelengths of the transmitters/receivers in a central office is simplified. Later stages of WDMs can tolerate larger fabrication errors, do not require flat passbands and birefringence compensation, and can tolerate full environmental temperature variations without feedback control in the central office.

Title: Call setup and service invocation in telecommunications networks
Inventor: LOBLEY NIGEL
IPC: H04M3/42
Filed: 1995-06-21
Granted: 2002-05-14
Abstract: A telecommunications network has switching means (12) configured such that a request from a first network termination (10) to establish a communications link with a second network termination is directed to the service processing means (13) which directs the switching means (12) to establish the link. This enables the user terminal (10) to direct service and call setup requests directly to the service processing means (13), the switch (12) not being involved with the call or service request until the service processing means (13) instructs it to participate, thereby minimising the establishment and allocation of resources until it is clear that such resources are required. A call can therefore be validated before any communications links are established, thus potentially offering economies in the operation of the system.

Title: In situ soil and/or residue remediation system and process using multi-level midspacing measurement
Inventor: PELLETIER MARC-ANTOINE
IPC: B09C1/10
Filed: 1995-06-28
Granted: 2002-09-10
Abstract: A system and process for in situ remediation of contaminated soils and/or residues is disclosed. These system and process take advantage of a radial flow irrigating/draining system and a multi- level sensor arrangement located at midspacing between parallel, horizontal conduit lines to create an environment propitious to the action of decontaminating agents (plants, microorganisms, salts, acids, bases, buffers, enzymes, substrates, surfactants, etc.). For example, a water-saturated zone is created and the level of water containing decontaminating agents is raised, maintained and/or lowered; the water-saturated zone encourages desorption or solubilization of soluble contaminants through adjustment and control of at least some parameters of reaction (time, temperature, pH, oxygenation, etc.) The system and process are easily adaptable for many classes of contaminants, including volatile compounds and light non-aqueous phase liquids, by further installing supplementary sets of conduit lines and pumps at adequate levels.  Remediation of a site may be conducted by alternating gaseous and liquid modes to optimize the conditions of reaction.
