Patent CA-2066229-C (CA)
Inventor: O'BRIEN JOHN TIMOTHY
IPC: H03M7/30

Abstract: Le système (100) amélioré de compression de données traite simultanément à la fois des chaînes de caractères répétés et une substitution textuelle de chaînes de caractères d'entrée. Selon ce système (100), on améliore la performance de techniques de compression de données basées sur la substitution textuelle, par l'emploi d'une représentation compacte permettant d'identifier les cas dans lesquels un caractère se trouvant dans le flux de données d'entrée est répété. On parvient à ce résultat par emboîtement d'un système (110) codant une longueur de passage, dans le système (111, 112, 120) de substitution textuelle. Cette structure ajoute la reconnaissance de passages d'un caractère répété avant que le processeur ne procède à l'opération de compression de données de substitution textuelle. On obtient une autre amélioration de performance en élargissant l'alphabet des symboles stockés dans le dictionnaire (120) du compresseur afin d'inclure à la fois les caractères du flux de données d'entrée et les comptages de répétition indiquant la répétition d'un caractère. La manipulation de ces comptages de répétition à l'aide de la technique de compression basée sur la substitution textuelle n'est pas différente de la manipulation de caractères, ou certaines modifications sont effectuées dans la manipulation de comptages de répétition.

Abstract: An improved seal (1) used in a hydraulic system having a piston rod (7) in a housing (5). The seal has stressing and sealing members (15, 17) with the latter being in point contact (23) with a piston rod un-der low fluid pressure and an additional point contact (29) with the piston rod under high fluid pressure. A shallow concavity (27) be-tween point contact (23) and the contact area entraps lubricating fluid when the seal is subjected to high fluid pressure. In another modifica-tion, the sealing member (17) has an incline (35) on the face in contact with stressing member (15). Thus, under high fluid pressure, stressing member (15) is forced up the incline (35), exerts increased pressure through the sealing member against the contact area and produces a high fluid pressure seal. In another embodiment, the sealing member (17) has a concave surface (25) to receive stressing member (15) such that it is centered, during low pressure operation, over a sealing con-tact area of the sealing member (17).

Abstract: Subtractive CDMA demodulation optimally decodes a coded information signal embedded in many other overlapping signals making up a received, composite signal. A radio receiver correlates a unique code corresponding to the desired signal to be decoded with the composite signal. As a result, subsequent correlations are performed with greater accuracy. Subtractive CDMA demodulation is enhance by decoding the composite signal in the order of the strongest to weakest signal strength. Interference caused by the presence of the strongest information signal and the composite signal during the decoding of weaker signals is removed. The individual information signals are assigned a unique block error correction code (44) which is correlated with the composite signal using Fast Walsh transforms. Correlated signals are recoded using inverted Fast Walsh transforms (46) and removed from the composite signal.

Title: Bridge construction
Inventor: TERON WILLIAM
IPC: E01D22/00
Filed: 1992-09-21
Granted: 1996-11-26
Abstract: A method of constructing a bridge using a two step composite construction process. In the first step, the region to be spanned is bridged with precast prestressed concrete elements that are designed as beams and complete permanent formwork to carry the dead load of the bridge, to provide a high density concrete protective shell giving a greater degree of protection against deterioration from the elements and to provide a very high quality of finish and architectural design, to provide a complete working platform for construction, and to eliminate the need for temporary scaffolding and formwork. In the second step, additional poured in place concrete is cast into the spaces created by the precast elements and serves as beams, post-tensioned to carry the live loads of the bridge. A bridge is thus created comprised of precast elongated elements supported on abutments at the sides of the spanned region, reinforced concrete beams contained by and between the adjacent elements, and a deck supported by the beams and elongated elements.

Title: An acetabular cup inserter
Inventor: FOLEY FRANK
IPC: A61F2/32
Filed: 1992-10-02
Granted: 2004-04-06
Abstract: This invention relates to a surgical instrument for inserting acetabular cups which may also be used to maintain pressure on the cup while the bone cement is setting. The instrument consists of a rigid central rod with a hemispherical button on its forward end and a palm pad on the other. A cup retainer (100) may be slid along the rod between forward and rearward positions, and a trigger mechanism (118), associated with a hand grip (116) is provided to commence rearward motion of the cup retainer (100) from its forward position.        When in its forward position, the cup retainer (100) may engage and retain an acetabular cup, as it is moved backwards, the hemispherical button holds the cup still, disengaging it from the retainer (100). The retainer (100) may then be moved to its rearward position while the cup is pressurised and excess extruded bone cement removed therefrom.

Title: Apparatus for measuring the flowrate of a fluid
Inventor: KIENE WILFRIED
IPC: G01F1/60
Filed: 1992-11-20
Granted: 1999-07-20
Abstract: Circuitry for a device to measure the flowrate of a fluid containing electrical charges which flows in a pipe section.  The device includes at least one electromagnet connected to a current source which generates a magnetic field through the pipe section and at least two electrodes whose central imaginary connecting line passes through the flow stream in the region of the magnetic field to measure the potential resulting from the charge displacements.  The circuitry also includes a timing circuit which periodically changes the strength of the excitation current from the current source to the electromagnet and switches a signal shunt which is connected between the electrodes and at least two signal memories.  The timing circuit also controls a current sink which is connected in parallel with the electromagnet.  The two signal memories, which store signals from the electrodes, are connected to a correction circuit to which the signals stored in the memories are supplied to produce an output signal corresponding to the flowrate of the fluid in the pipe section which is only minimally dependent of the flow profile or the level of the fluid in the pipe section.

Granted: 2004-10-19
Abstract: A filter device with a preferably hollow-cylindrical, pleated filter element which is arranged concentrically around a cylinder axis and through which a medium to be filtered passes. Seals are necessary on the filter device so that the medium to be filtered will not be able to leak out and so that the filter element, which typically is constructed of filter paper, must be fixed in place together with its pleats. Advantageously, an elastic composition can be disposed as a seal on at least one of the ends of the filter element, and after curing the elastic composition will fix the pleats of the filter element and will have sufficient residual elasticity to seal the filter element with respect to a central mounting tube on which it is to be mounted.
