Patent CA-2238922-C (CA)
Inventor: ZWARICH RON
IPC: A01B63/22
Filed: 1998-05-28
Granted: 2005-05-17
Abstract: An agricultural implement provides improvements in ground-working implements having both a lowered ground-working mode and a raised transport mode wherein means are provided to offset the effects of the moment forces created in the working mode. A fluid circuit is connected to a fluid actuator for controlling forces exerted thereby between a hitch member and the implement main frame and it is operable in a working mode to exert a resilient biasing force on the hitch member thus enabling pivotal floating motion of the hitch member while simultaneously countering force moments applied to the main frame by the ground-working tool. This system is also operable in a transport mode wherein the actuator exerts sufficient force between the hitch member and the forward end of the main frame as to assist in lifting and maintaining the implement in a raised transport mode.

Title: Chapeau dote d'une poche de rangement
Inventor: DEL PIZZO FRANK C JR
IPC: A42B1/24
Filed: 1996-12-06
Granted: 2007-07-17
Abstract: Un chapeau (10) a une poche de rangement (22) disposée, sur la face intérieure dudit chapeau, entièrement au sein d'un espace mort (30) se trouvant à l'avant du chapeau et s'étendant d'un emplacement situé au-dessus d'une garniture intérieure (28) du chapeau vers la calotte du chapeau (10). Lorsque le chapeau (10) est porté, il existe, au niveau de son espace intérieur, un espace mort (30) où le chapeau n'est pas en contact avec la tête de la personne et qui s'étend typiquement d'un emplacement situé juste au-dessus de la garniture intérieure (28) jusqu'au fond de calotte du chapeau (10), du fait de la différence entre la courbure de la tête de la personne qui porte ledit chapeau et celle du chapeau (10). En disposant une poche de rangement (22) dans cette zone, on évite la création de bosses disgracieuses ainsi qu'une sensation de gêne qui pourrait résulter de la pression exercée sur la tête de la personne portant le chapeau par les objets rangés à l'intérieur de la poche.

Title: Method and apparatus for enhanced partial packet discard
Inventor: KING GREGORY LLOYD
IPC: H04L12/56
Filed: 1998-07-09
Granted: 2004-04-13
Abstract: In an enhanced partial packet discard (PPD) methodology, if an end-of packet cell is discarded for non-PPD reasons, all non-end-of packet cells of the immediately following packet are discarded. When an end-of-packet cell may validly be discarded, a switch faced with an end-of-packet cell may discard that cell if the last cell admitted to the buffer was an end-of-packet cell. To reduce the likelihood of having to drop end-of-packet cells, a buffer is configured to include a partial packet discard threshold such that the buffer space between that threshold and the end of the buffer is reserved for use by end-of-packet cells.

Abstract: A method for supplementing a digital image with picture elements, by which prediction signals having small errors can be generated for a digital image in which objects move greatly through a process which does not cause a long delay time and does not need a large quantity of calculation. In the method, the image is divided into areas. The insignificant sampled values of the areas containing the boundary of the shape of an object are transformed with a function of significant picture element values near insignificant picture element values and used to supplement the digital image. A digital image encoder and a digital image decoder both using the method are also disclosed.

Abstract: L'invention porte sur une composition utilisable comme mastic flottant, consistant en un mélange d'une phase solide discontinue de microbilles et d'une phase liquide continue visqueuse comprenant un polydiméthylsiloxane. La viscosité du polydiméthylsiloxane de la phase continue est comprise entre 100.000 et 2.000.000 cP. Cette viscosité est obtenue du fait de l'incorporation de molécules de polydiméthylsiloxane d'une masse moléculaire suffisamment élevée. Le confinement dans d'autres matériaux est facultatif. Des colorants, pigments, particules, fibres, feutres ou tissus additionnels peuvent conférer une visibilité, une résistance, une rigidité, une concentration en matières sèches ou une résistance de frottement supplémentaires. Des propriétés associées de malléabilité ainsi que d'isolation thermique, électrique, de protection contre les vibrations et les chocs et d'isolation acoustique, rendent également cette composition des plus utile pour d'autres applications exigeant de telles qualités.

Title: Modified protein c and methods of use thereof
Inventor: SMIRNOV MIKHAIL
IPC: C07K19/00
Filed: 1997-11-07
Granted: 2005-02-22
Abstract: Modified Protein C molecules have been made which substitute the gamma carboxylglutamic acid (Gla) region of another Vitamin K dependent protein, most preferably prothrombin, for the native region of the Protein C. A modified Protein C molecules has been made which substitutes the gamma carboxylglutamic acid (Gla) region with the corresponding region of prothrombin. The modified or chimeric protein C has advantages over the wild-type protein C since it is less sensitive to inhibition by some natural antibody inhibitors of protein C (which would otherwise decrease the ability of the protein C to act as an anticoagulant) and which do not need the same cofactors or same amounts of cofactors, and can therefore be effective in patients with lowered levels of the cofactors such as protein S or the lipids present in elevated levels in platelets such as phosphatidyl ethanolamine (PE). The anticoagulant activity of the chimera was tested in normal and factor V Leiden plasma. The chimera was approximately ten times more effective in inhibiting factor V Leiden plasma clotting.

Abstract: The present invention relates to an artificial leather having a nap of low orientation on the surface and short dense fibers, thereby having a good nubuck-like appearance texture and hand. It also relates to a production process thereof. The present invention provides an artificial leather having a nap surface of ultra-fine fibers on at least one side, which is formed by applying an elastic polymer to an ultra-fine fiber-entangled substrate, characterized by being 0.3 g/cm3 or more in the apparent density of the artificial leather, being 0.5 mm or less in the nap length, and being 25% or less in the R value obtained from the goniometric reflectance distribution measured with the nap surface rotated from 0 degree to 180 degrees using a goniophotometer. The present invention also provides a process for producing a nubuck-like artificial leather, in which a sheet obtained by applying an elastic polymer to an ultra-fine fiber-entangled substrate is raised to produce a napped sheet, comprising the steps of applying an elastic polymer to an ultra-fine fiber-entangled substrate, substantially solidifying the elastic polymer, immersing the polymer-deposited fiber-entangled substrate into a swelling agent of the elastic polymer, to swell the elastic polymer, compressing the sheet in the normal direction of the sheet, removing the swelling agent by an aqueous solvent, and raising the sheet on at least one side.

Inventor: AZELMAD ABDELLAH
IPC: F41A17/06
Filed: 1999-11-24
Granted: 2002-08-13
Abstract: An automatic firearm safety system where power consumption is reduced and safety is increased is disclosed. The system includes a movement detector operatively associated with a trigger of a firearm for detecting movement of the trigger. The system also has a transceiver operatively associated with the movement detector for sending a coded signal when movement of the trigger has been detected. The coded signal is received by at least one remote token which receives the coded signal and transmits a coded acknowledgement signal upon receipt of the coded signal. A solenoid is also provided for locking and unlocking the trigger, operatively associated with the transceiver for allowing operation of the trigger and thereby the firing of the firearm when the coded acknowledgement signal has been received by the transceiver. The system may include two tokens, both of which are worn by the authorized user. In this case, the transceiver further includes an anti-collision module to discriminate between the different tokens and select which one will be permitted to issue the coded acknowledgement signal. Also preferably, the transceiver includes an anti jamming module. Since verification of the token is done every time the trigger is depressed, safety is increased.  Furthermore, since bi-directional RF communication is effected only when the trigger is depressed, power consumption is reduced.
