Patent CA-2281063-A1 (CA)
Inventor: MAO KAI MING
IPC: A47H5/032
Filed: 1999-08-24
Abstract: A drapery opening and closing system for opening and closing a single drape or two drapes, and a method of opening and closing a drape. A reversible electric motor, to which a winch member is rotalably coupled, is affixed to a wall proximate a window at an approximate mid-vertical height of such window. An elongate cord having a first end fixed to the wall and another coupled to such winch member, encircles the drape. Upon actuate of the motor, adjustible timing means permits operation of the motor for a predetermined interval of time to allow the elongate cord to be wound onto such winch member, thereby causing the cord encircling the drape to constrict and thereby bunching the drape together thereby drawing it from the window. Reversal of the direction of the winch allows unwinding of the cord to thereby allow the drape to fall back into position thereby covering the window.

Title: Method for using a vegetable biomass and a screw press to carry out said method
Inventor: GRASS STEFAN
IPC: A23K10/10
Filed: 1998-03-09
Abstract: According to the invention, biomass from an agricultural crop in a naturally damped state is crushed in screw presses for further processing. After pressing to separate a low-solid phase, the remaining high-solid phase is processed with pressurized vapor. Expansion occurs, a vapor phase is separated and the high-solid phase is cooled, wherein substances are decomposed under the influence of enzymes and/or fermentation with microorganisms, while a gaseous phase is separated. A low-solid and a high-solid phase is separated in the remaining mixture. All separated phases are used to obtain preferably ethanol, protein concentrate and fibers or are reprocessed. A screw press (200) enabling continuous implementation of said method comprises axially disposed inline chamber areas (201...204) with a common integral shaft (205) and screws (206...211) arranged thereon. Said chambers are tightly sealed off from each other by compacted material plugs. The aqueous liquid phase is reprocessed (215...217) in the opposite direction to said material. An additional chamber area (218) having its own screw can connect two partial areas (203...204) to each other, thereby forming a loop with the advancing material.

Title: Metastasis models using green fluorescent protein (gfp) as a marker
Inventor: TAN YUYING
IPC: A01K67/027
Filed: 1998-04-28
Abstract: A method to follow the progression of metastasis of a primary tumor, which method comprises removing fresh organ tissues from a vertebrate subject which has been modified to contain tumor cells that express GFP and observing the excised tissues for the presence of fluorescence is disclosed. The fluorescence can also be monitored by observing the tissues in situ. Vertebrate subjects which contain GFP  producing tumors are useful models to study the mechanism of metastasis.  In addition, subjects already harboring tumors can be treated so as to modify the endogenous tumors to contain GFP. This permits clinical applications. Finally, by injecting a contrast dye into a subject harboring a GFP-labeled tumor, angiogenesis in the tumor can be observed directly.

Patent CA-2312463-A1 (CA)
Title: Chromatic dispersion compensation
Inventor: FELLS JULIAN A
IPC: H04B10/18
Filed: 2000-06-20
Abstract: An optical waveguide provided with a linearly chirped Bragg reflective grating can be employed as a device that provides linear dispersion compensation.      The amount of the linear dispersion thereby provided can be rendered adjustable by adjustment of the magnitude of axial strain imposed upon the grating. If the chirp is purely linear, and if also, the strain is at all times uniform along the length of the grating, adjustment of the strain magnitude will have no such effect. This requires the presence of a quadratic chirp term, but such a term introduces its own transmission penalty. This penalty is compensated at least in part by causing the light to make a reflection in a further Bragg reflection grating whose quadratic component of chirp has the opposite sign to that of the other Bragg reflection grating, but a substantially matched modulus. The effect of the strain is to scale the effective pitch of the Bragg reflection grating by scaling its physical pitch. An alternative way of achieving a similar effect is to change the effective refractive index of the waveguide in which the grating is formed, for instance by changing its temperature.

Title: Bed restraint for an adsorber
Inventor: ACKLEY MARK WILLIAM
IPC: B01D53/04
Filed: 2000-08-30
Abstract: An axial flow adsorber apparatus includes a bed of adsorbent material, a barrier in the form of an open-cell material combined with a distribution screen or baffle, graded balls, and an inflatable bladder.      The adsorbent bed is the active adsorbent required for a separation process. The barrier combines the open-cell material, which provides uniform retention of all adsorbent material, with the distribution screen, which provides uniform flow and pressure distribution across the bed. The barrier substantially covers a top surface of the adsorbent bed to prevent fluidization of the bed. Graded balls on the barrier uniformly distribute a downward pressure supplied by the inflatable bladder above the balls. The uniform pressure is transmitted through the balls to the barrier to further suppress fluidization. The balls also serve to direct gas flow in the upper end of the vessel and reduce void volume in the apparatus that would trap product gas. The flexible bladder maintains a uniform pressure on the bed while also eliminating a major portion of the void volume in the heads of the adsorber apparatus.
