Patent CA-2383929-A1 (CA)
Title: Hydraulically driven fishing jars
Inventor: ROPER CHARLES A
IPC: E21B31/113
Filed: 2000-09-08
Abstract: A fishing jar (11) is placed in a work string for delivering blows to a stuck object in a well. This fishing jar (11) utilizes energy stored in the work string for delivering the blow, rather than having a main spring of its own. The fishing jar (11) uses hydraulic pressure to move a piston member (35). The piston member (35) engages a firing member (75) when it reaches one end of its stroke.     The directional valve (45) then directs fluid to the other side of the piston (35) to cause the piston (35) to move in the opposite direction.     When it starts to move in the opposite direction, the firing member (75) will provide a restrictive load against that movement. Once the pressure builds to a high enough level, it will move the housing (13) relative to the piston (35), which is restricted from movement by the firing member (75). When the housing (13) moves, it elastically deforms the work string, storing energy in the work string. The firing member (75) will release the housing (13) once the housing (13) reaches the end of its stoke. The housing (13) has a hammer surface (97) that strikes an anvil (95) once released.

Patent CA-2394576-A1 (CA)
Inventor: LEWIS KATHY A
IPC: A61K48/00
Filed: 2000-12-14
Abstract: Inhibins and activins are protein hormones that reciprocally modulate a diversity of regulatory pathways. Competitive binding experiments revealed that betaglycan, the type III TGF-.beta. receptor, also functions as an inhibin receptor. Betaglycan augments the binding of inhibin to the ActRII  activin receptor. By augmenting inhibin binding to ActRII, betaglycan effectively sequesters ActRII away from activin and thereby reduces activin signaling. In addition, the ActRII-betaglycan complex may generate novel signals distinct from those initiated by activin signaling via ActRII and ALK4. Betaglycan is produced in discrete nuclei of the rat brain and by specific cell types within the adult rat pituitary, testis, and ovary. The presence of betaglycan within inhibin-responsive tissues and cell types, together with the ability of this protoglycan to bind inhibin and to confer inhibin sensitivity, is consistent with a role of betaglycan as an inhibin-specific receptor mediating inhibin responses within various tissues.

Abstract: A method and system (10) for providing flexible access to Internet sites is described. The system (10) includes a database (30) of Internet sites that have been categorized so that the system determines the category of information (40) that a user is accessing on the Internet. The system (10) is also programmed so users are only allowed to access sites within a particular category a limited number of times. Moreover, users can request a postponed access, wherein the site they are requesting is stored on a server, and available to the user at a later time (44). In addition, if a user chooses to access a site that is within certain predefined categories, they are presented with the option of retrieving the page, but notified that their access will be logged to a file.

Abstract: L'invention concerne une composition améliorée de balle de golf multicouche ainsi que les balles réglementaires produites avec ces compositions. On réalise ces balles en produisant un noyau (10) plus petit et plus léger et en incorporant des particules métalliques ou une autre charge de poids élevé dans les compositions de revêtement. On obtient ainsi une balle (18) de golf moulée présentant un lestage amélioré du périmètre interne. Les particules sont de préférence incorporées dans la couche de revêtement (14) interne (chape) (14) d'une balle (10) de golf solide trois-pièces multicouche. La taille et le poids du noyau (10) sont réduits afin de produire au total une balle de golf qui respecte ou se situe au dessous de la limite de poids maximale de 1,62 onces fixée par l'United States Golf Association. Il a été démontré que la présente combinaison permet de produire une balle de golf présentant un moment d'inertie accru et/ou un rayon de giration plus important, générant ainsi une rotation propre plus basse. On obtient ainsi une balle de golf présentant des caractéristiques de distance améliorées sans que les caractéristiques de sensation et de durabilité ne soient affectées.

Inventor: LAKHANI ABDUL-KARIM
IPC: H04N7/10
Filed: 2001-03-30
Abstract: The return path for a signal in a cable system uses a portion of the 50-750 MHz frequency band to send signals from each set-top box therein to a receiver at the feeder line end. A band stop filter is placed in each auxiliary feeder line to prevent the return signal from set-top boxes being received by more than one feeder line end. The feeder line end also has a receiver and high to low frequency converter which retransmits the signals in the low portion (5-50 MHz of the frequency spectrum) to the headend. High pass filters are placed at taps going into homes to prevent low frequency noise from home devices, home wiring and drop wiring from entering the feeder lines. This system eliminates virtually all ingress noise picked up by the collection of set-top boxes, home wiring and drop wiring from entering the cable system.

Patent CA-2409690-A1 (CA)
Inventor: NISHIDA YASUAKI
IPC: H04H40/54
Filed: 2002-10-24
Abstract: This invention addresses itself to the task of securing excellent narrowband transmission quality when transmitting audio signals such as voice and music, or various kinds of multimedia signal, by means of unidirectional or broadcast communication systems. Excellent demodulation characteristics are obtained by reducing the required transmission bandwidth by using SSB modulation technology, and by performing RZ SSB demodulation at the receiving side. The sideband and the carrier component are transmitted at a sufficient distance from one another in the frequency domain so that even if frequency stability in the transmitting and receiving circuits is not very high, there is little likelihood of quality deterioration due to frequency instability, and so that the receiving circuit is easier to implement, since less sharply selective bandpass filters are required. At the receiving side, the sideband and the carrier component undergo separate frequency conversions that convert them to signals that are suitable for RZ   SSB demodulation.
