Patent CA-2216440-C (CA)
Inventor: DOMIGAN CHARLES
IPC: H02G3/18
Filed: 1997-09-25
Granted: 2006-01-10
Abstract: A non-metallic floor box for use in electrical in-floor power and communication distribution systems includes a plurality of sets of vertically aligned indexing teeth formed in the interior of the housing side wall. An adapter ring is sized for insertion into the housing interior for supporting an activation kit above the housing interior compartment. The adapter ring has flanges extending from its periphery which are positioned to reciprocally mate with the vertical rows of teeth when the adapter ring is inserted into the housing interior compartment. The flanges and teeth are constructed to permit the ring to be inserted into the housing but to restrict its removal from the housing after its insertion therein. An activation cover is securable to the top of the adapter ring and extends beyond the perimeter of the side wall to limit the distance the adapter ring can be inserted into the housing. The floor box accommodates dual services through the use of two sets of parallel aligned conduit hubs and a divider which is insertable into the housing interior between the two sets of conduit hubs. The closed top of the housing acts as a concrete cover during the pouring of the floor, and as a temporary debris cover after it is cut off but prior to activation of the floor box. Gradient markings on the interior of the floor box provide a quick and accurate measurement of interior floor box volume for inspection and building code compliance.

Abstract: Method and apparatus for detecting pressure waves caused by movement of a body organ, transmitted through a catheter (18) to an implanted medical device employing a pressure wave transducer (32) mounted in relation to the proximal end (40) of the catheter (18). The system may also include a reference transducer (34) having the same pressure wave response characteristics as the pressure wave transducer (32) but isolated from the proximal connector end (40) for providing a reference signal including common mode pressure wave noise that both transducers (32, 34) are simultaneously subjected to. The pressure wave signal and the reference signal are preferably amplified, bandpass filtered, stored, telemetered out or used to trigger a device operation. The pressure and reference wave transducers (32, 34) preferably are piezoelectric crystal transduces or accelerometers in direct or indirect mechanical contact with the proximal connector end (40) of the catheter and is encapsulated from the body within a device connector assembly (20). Cardiac pressure waves and respiration pressure waves are both transmitted proximally through the lead body (18) to the pressure wave transducer (32). Pressure wave signals may be derived in parallel to detect particular characteristic of the cardiac and/or respiratory cycle to provide timing signal(s) for controlling the device operations.

Abstract: A rotary mining bit is particularly suitable for use in the drilling of blasting holes in the mining industry, but may also be used for drilling wells and the like in both soft materials and hard, rocky materials. The bit comprises a central hollow body with a plurality of wings extending outwardly therefrom, with each wing having a leading edge with a plurality of cutting tooth sockets disposed therealong and each of the sockets having a cutting tooth affixed therein. The outermost cutting teeth on each wing describe a gauge row diameter, which defines the diameter of a hole formed using the present bit. The outermost cutting teeth are each angled outwardly, away from the axis of the bit and lateral edge of the wing. An inner or apex row of teeth describes a smaller cutting circle diameter, with intermediate teeth on each row preferably being irregularly spaced between the outermost and innermost teeth on each respective wing, so each intermediate tooth describes a different diameter circle from the others. The back of each cutting tooth is accessible through the open back of its respective socket, allowing the teeth to be driven out for replacement as required without need for special tools or fittings. The large central passage through the body of the bit allows air and/or liquid coolant and/or lubricant to pass through the body essentially unimpeded, and to resist clogging or plugging due to debris in the hole during drilling operations.

Abstract: A storage using a memory device with a continuous transfer function as typified by an SRAM (Synchronous Random Access Memory) or a DRAM (Dynamic RAM) with an EDO (Extended Data Out) is disclosed. As for the detection/correction of data errors, the storage reduces the ratio of the number of check bits to the number of data bits by effectively using a burst transfer function available with the memory device. This allow a single memory device to recover from faults. This can be done with means for dividing an ECC unit into a plurality of parts in a continuous transfer direction and writing one of them in the memory device at a time, and means for detecting/correcting the errors of data read out of the memory device while buffering them on an ECC basis.

Title: Reactor and method for solid phase peptide synthesis
Inventor: TOMAZI KEITH
IPC: C40B60/14
Filed: 1998-02-10
Granted: 2004-04-20
Abstract: A solid phase peptide synthesis reactor system (1) and method of operating the reactor are provided. The reactor system (1) includes a basket (17) rotatable about an axis within a housing (7) and a sump/receiver (5) which delivers fluid to, and collects fluid from, the housing (7). The basket (17) has a perforate side (23) wall against which a resin cake (R) for the peptide synthesis is formed. The reactor (7) and sump/receiver (5) form a loop or circuit through which solutions are circulated. The circulation of the solutions prevents the reactor (7) from flooding so that the basket (17) will not be submerged in solution and allows for the use of less liquid. Thus greater amino acid concentrations may be used. The method includes forming a resin cake (R) of uniform depth on the wall (23) of the basket (17), and spraying the solutions against the resin cake while spinning the basket. The solutions will pass through the resin cake (R) and drain to the sump (5) to be circulated or recycled through the system or discharged from the system. Before a subsequent solution is introduced into the reactor system (1), the prior solution is purged from the system to help control exposure time of the peptide to the solutions.

Abstract: Procédé d'évaluation de la qualité d'un signal test audio (14) dérivé, par codage et décodage, d'un signal de référence audio (12), consistant à effectuer une comparaison du signal test audio (14) avec le signal de référence audio (12), pour ainsi dire, derrière le limaçon de l'oreille humaine. Tous les effets de masquage ainsi que la fonction de transmission de l'oreille sont appliqués de la même manière au signal de référence audio (12) et au signal test audio (14). En outre, le signal test audio (14) est fractionné, conformément à sa composition spectrale, au moyen d'une première batterie de filtres (20), en filtres de fonctions filtrantes se différenciant les unes des autres, définissant des fonctions spectrales interférant en fréquence, fonctions qui sont respectivement établies en se basant sur les courbes d'excitation de l'oreille humaine pour les fréquences moyennes filtrantes respectives. Le signal de référence audio (12) est fractionné de la même façon, conformément à sa composition spectrale, au moyen d'une deuxième batterie de filtres (16) synchronisée avec la première batterie, en signaux partiels de référence audio (18). Après quoi, une différence de niveau est formée, par tranches spectrales entre les signaux partiels test audio (22) appartenant aux mêmes tranches spectrales, et les signaux partiels de référence audio (18). Pour l'évaluation de la qualité du signal test audio (14), on détermine par tranche spectrale une probabilité de détection en vue de détecter une erreur de codage du signal test audio (14) dans la tranche spectrale considérée, sur la base de chaque différence de niveau.
