Patent CA-2425982-A1 (CA)
Title: Uninterruptible oil supply system
Inventor: RAGO GIUSSEPPE
IPC: F01D25/18
Filed: 2001-10-23
Abstract: An oil supply system supplies oil under pressure to a bearing enclosure during normal positive gravity conditions as well as negative and zero gravity conditions. A closed oil storage tank containing a volume of oil below a gas filled headspace with primary drain in a bottom portion normally supplies a pressure pump which passes a pressure control valve before entering an inlet of the enclosure. In negative gravity or zero gravity conditions oil is absent from the tank bottom and the primary pressure pump is starved of oil. The invention solves this problem with an auxiliary tank outlet disposed above the bottom drain (at the top and/or sides of the tank) and the oil-air separator separates the air before pumping the oil under pressure to the bearing or journal enclosure past a directional switch.

Abstract: Dans un sous-système d'émission-réception d'un dispositif informatique portatif, la consommation de puissance est réduite lorsque ledit sous-système reçoit des données de média en mode continu. Le dispositif informatique portatif reçoit une première partie des données de média par l'intermédiaire d'un premier canal de communication et une deuxième partie des données de média par l'intermédiaire d'un deuxième canal. Le dispositif informatique portatif peut recevoir la première partie des données bien avant de recevoir la deuxième partie des données et peut utiliser une connexion sans fil pour recevoir la deuxième partie des données. Le dispositif informatique portatif peut interrompre la connexion sans fil une fois qu'il a reçu la deuxième partie des données, ce qui réduit la consommation de puissance globale du dispositif sans fil. Une application client à l'oeuvre dans le dispositif informatique portatif réassemble le fichier de média à partir des première et deuxième parties.

Filed: 2003-05-21
Abstract: In a sprocket for use with a roller chain, a wear limit marker, having a different color from that of the base material of the sprocket, is provided on side surface of a sprocket tooth adjacent to a keyway. The wear limit marker is disposed on an imaginary line extending in the direction of the pressure angle, and is located in a hole or groove provided in a side surface of the sprocket tooth. The marker makes it possible to determine easily and reliably whether or not wear at the location at which wear of a sprocket tooth proceeds most rapidly is within a predetermined limit, and the location of the marker makes it possible to evaluate wear conditions even when the sprocket is installed in a machine.

Title: Frequency domain channel estimation for multiple channels using wiener minimum mean squared error (mmse) filtering
Inventor: HUDSON JOHN E
IPC: H04L1/06
Filed: 2002-04-03
Abstract: Multiple Steiner codes are transmitted as bursts (s11, s12,s33, 560, 524) from multiple base stations (182, 184, 186) having one or more transmit elements (174, 176, 178, 180), with successive bursts providing an extended training sequence (260) for use in channel estimation at an addressed unit (172), such as a mobile handset. Accurate channel estimation is possible through the use of Wiener frequency domain (252) MMSE deconvolution (266, 518) combined with frequency domain spatial decoupling matrices, with quasi-orthogonal pseudo-noise sequences (502, 504, 520, 522) allocated to base stations and their antenna elements. The use of Steiner codes to supplement Wiener frequency domain MMSE deconvolution and frequency domain spatial decoupling results in the possibility of allocating only a single training sequence to each base station provided that the training sequence is of sufficient length to encompass all multiple time-translated channel impulse responses (<i>H</i>).  Estimates may be refined iteratively by minimising the MS minimum squared error of demodulated pilot symbols (1540). Estimates may also be refined by removing taps from the impulse response which are insignificant based on a relatively long-term power-delay profile for the channel (272).

Title: Multiple-layered patches for teeth whitening
Inventor: YUN SEI-YOUNG
IPC: A61K8/37
Filed: 2002-06-21
Abstract: The present invention relates to a dry type patch for teeth whitening with multiple-layered structure of three or more layers. More particularly, in the dry type patch, a contact adhesive layer contains no peroxide and comprises a hydrophilic glass polymer as a base polymer so that it may have substantial adhesive strength when hydrated by water, an active material reservoir layer comprises peroxide as a teeth whitening agent, and a backing layer is impermeable to water. The dry type patch of the present invention has a superior teeth whitening effect and an excellent stability of peroxide in the patch at a high temperature since the peroxide-containing layer is covered with and protected by other layers.

IPC: C07K19/00
Filed: 2004-07-05
Abstract: A method to aid in the efficient construction of fusion proteins involving multiple domains is provided in which a new expression vector is created to allow rapid generation of a library of cassettes. Cassettes have a standard vector structure based on four specific restriction endonuclease sites and using a subtle property of blunt or compatible cohesive end restriction enzymes, they can be fused in any order and number of times. Furthermore, the insertion of PCR products into our expression vector or the recombination of cassettes can be dramatically simplified by screening for the presence or absence of a detectable activity.  The utility of this new strategy was demonstrated by the creation of basic cassettes for protein targeting to subcellular organelles and for protein purification using multiple affinity tags.
