Patent CA-2396104-A1 (CA)
Inventor: HASHA RICHARD
IPC: H05B37/02
Filed: 2000-02-03
Abstract: A method and system for implementing functions in a class that inherits an interface and that inherits an implementing class which implements the interface. A forwarding system adds to the class for each virtual function a forwarding implementation of that virtual function. The forwarding implementation forwards its invocation to the implementation of that the virtual function in the implementing class. The forwarding system implements a special forwarding instruction that specifies the interface and implementing class. A developer of a class that inherits the interface and the implementing class inserts the forwarding instruction into the class definition. When the forwarding system encounters such an instruction during compilation of the class definition, the forwarding system provides an implementation of each virtual function of the interface that forwards its invocation to a corresponding virtual function in the implementing class. The forwarding system also forwards virtual functions of any direct or indirect base interface of the interface to the implementing class.

Patent CA-2399743-A1 (CA)
Title: Extruding device
Inventor: FRIEDRICH JAROMIR
IPC: B29C48/345
Filed: 2002-08-26
Abstract: A plastic material extruder combines the features of a generally flat rotatable disc and a generally flat opposed stator. At least one of the two is heated by heating elements. The two define a processing gap into which a hopper for feeding a plastic material mixture is discharged. The rotor and the stator develop a high shear force which further heats up the processed mixture in addition to the heating delivered by the heating elements. At the center of the disc/stator assembly, an axial force developing device such as a ram or a feed screw or screws is adapted to further compress and extrude a mixture of the thermoplastic components and thermosetting components, the latter being comprised of crumbled pieces of used tires. The extruder is shown in two embodiments, one injecting the processed alloy into a mold, the other producing pellets of the processed alloy.

Title: Melanges de petrole brut et de cire de fischer-tropsch presentant une forte teneur en cire
Inventor: COOK BRUCE RANDALL
IPC: C10G70/00
Filed: 2001-03-28
Abstract: L'invention concerne un procédé permettant de produire un mélange de cire et de pétrole brut qui peut être pompé à température ambiante. La cire est, de préférence, une cire de Fischer-Tropsch. La température du pétrole brut est contrôlée à un niveau inférieur à la température de dissolution de la cire.

Abstract: "On the machine screw threaded pressure equalising coupling titled as "Woolford's Pressure Equaliser" in the laid open application Number 2,323,161 that is used to lock two disc wheels together into a dual wheel assembly, onto a bus or truck axle, the drive handle being an unmarked square, is the industry norm for an unequalised coupling. Therefore, the equaliser is not easily recognisable as being a different coupling There is no indication as to the direction of the pressure required to tighten the equaliser and no calibrating marks to indicate when the desired pressure has been attained and and whether it is being maintained. The purpose of this invention is to change the readability of the equaliser from an intangible to a tangible form."

IPC: B01F3/08
Filed: 2001-05-02
Abstract: A mixer for mixing a solid or an additional liquid into a liquid within a mixing vessel using a vortex action obviates direct application of the introduced solid or liquid with the downstream end of the vortex by bending the axis of rotation of the vortex. In one form this is effected by laterall y offsetting a discharge outlet of the mixing vessel relative to the upper end  portion of the vessel into which the liquid is introduced. The vortex within  the vessel is maintained at a predetermined level by applying a static head to the liquid in the vessel. This is preferably achieved by maintaining a predetermined static head of mixture in an outer vessel into which the mixin g vessel discharges.

Title: Glass ceramic mass and use thereof
Inventor: SCHILLER WOLFGANG ARNO
IPC: H05K1/03
Filed: 2001-08-31
Abstract: The invention relates to a glass ceramic mass, comprising at least one oxide  ceramic, containing barium, titanium and at least one rare earth metal Rek a nd at least one glass material, containing at least one oxide with boron and at  least one oxide of a rare earth metal Reg. The glass material further contai ns either an oxide of a tetravalent metal Me4+, or at least one oxide of a pentavalent metal Me5+. A compression of the glass ceramic mass occurs above  all by viscous flow. A low vitrification temperature can thus be achieved. Crystallisation products are produced during and/or after the compression. T he rare earth oxide and the crystallisation products can be used to pre-determi ne each of a dielectric material property of the glass ceramic mass in a wide range such as permittivity (15 - 80), Q (350 - 5000) and Tf value (.plusmn. 20 ppm/K). The glass ceramic mass is characterised by a vitrification temperatu re of below 850 ~C and can thus find application in LTCC (low temperature cofir ed ceramics) technology for the integration of a passive electrical component i n the volume of a ceramic multi-layer body. Suppression of a lateral shrinkage  may be achieved in a composite with a ceramic film blank made from another ceramic material compressed at a higher temperature.

Abstract: Method for determining, monitoring and updating correction data for correcting measured value distortions and for calibrating liquid-filled transmission systems, via which signals from the patient detected in the body of a patient are transmitted to an external measured value receiver, in particular for invasive pressure measurements in cardiology, intensive care medicine and anaesthesia. The correction data are determined in the frequency range for each frequency from statistics of the signals from the patient measured at this frequency, in particular from the transmission function obtained from the signal from the patient. In the determination of the correction data, empirically checked assumptions about the corresponding statistics of undistorted signals from the patient and general properties of the transmission function are used.
