IPC: A61B17/08
Filed: 2004-09-17
Abstract: A buttress (12) for use with surgical staplers (10) that does not require adhesive to securely fasten the buttress (12) to the stapler (10). The buttress (12) has an adaptive opening through its central region with a diameter smaller than the outer diameter of the stapler anvil (16). Because of relief features built into the buttress (12), the stapler anvil (16) may be pulled through the buttress material without causing permanent alteration ot the buttress (12). These relief features may be provided regardless of whether the buttress (12) is made of inelastic or elastic materials. The buttress (12) is generally circular in shape with an outer diameter sized to coincide with the outer diameter of the stapler body staple compression surface (20) and the outer diameter of the anvil compression surface (18) of a circular stapler (10) with which it is used.

Abstract: Disclosed is a composition for treating prostate cancer. The composition for treating prostate cancer comprises as an effective ingredient a radioisotope-chitosan complex that includes a therapeutic radioisotope emitting beta radiation and chitosan. Also, the present invention discloses a kit for preparing the composition. When directly administered to a prostate cancer tissue, the radioisotope-chitosan complex is deposited in the applied target site while not leaking from the applied target site, and strongly inhibits the growth of prostate cancer cells while minimizing the side effects of conventional therapies, including urinary incontinence, urethral stricture and rectal bleeding. In addition, the radioisotope-chitosan complex may be used as an effective therapeutic agent for hormone-independent prostate cancer that is resistant to hormone therapy.

Title: A device and method for non-contact sensing of low-concentration and trace substances
Inventor: PASMANIK GUERMAN A
IPC: G01N21/17
Filed: 2005-01-14
Abstract: A device for non contact detection of low concentration substances outside a laboratory environment is disclosed. A probing laser emission is split into two linear orthogonally polarized emission components and one component is delayed in time relative to the other. Both components are directed to a focal region that is proximate to a target medium thought to contain the substance to be detected. Between the arrival of the first and second emission components, an excitation light pulse at a wavelength corresponding to an absorption line in the spectrum of the substance is directed to the focal region. If vapours of the substance are present, they will be heated by the excitation pulse and will change the index of refraction of the focal region before the second emission component passes through it, thus altering the phase of the back-scattered emission returns. The device delays the first returned component by an equal delay and coherently couples the returned emission components. The amplitudes of the orthogonally polarized returned emission components are compared. If the probing laser is pulsed, the ratio of the polarized pulse components is observed to indicate the presence of the substance. Optionally, reference pulses for which no excitation pulse is generated may be introduced to provide a reference signal to rule out effects due to the intrinsic polarization caused by passage of the emission through optical components. If the probing laser is a continuous wave laser, the presence of transients timely correlated with excitation pulses in the detected continuous wave signal will indicate the presence of the substance.

Abstract: A fuel cell system comprises: a stack unit having a cathode and an anode and generating electricity by an electro-chemical reaction between hydrogen and oxygen; a fuel supply unit for supplying hydrogen to the anode of the stack unit; an air supply unit for supplying air to the cathode of the stack unit; and a gas-liquid separator having a cooling device for contacting off-gas supplied to the fuel supply unit from the stack unit and thereby condensing moisture included in the off-gas.   In the fuel cell system, moisture included in the off-gas is removed by the gas-liquid separator and thus combustion inside the burner is actively performed. As the result, steam is stably supplied to a steam reformer and thus a reforming reaction is smoothly performed, thereby enhancing an entire function of the fuel cell system.

IPC: E01H5/10
Filed: 2006-04-20
Abstract: During the winter season the accumulation of thick layers of ice on vehicle surfaces is difficult to remove and, if not removed, poses a public safety hazard. To date, no device has adequately addressed this problem. The invention put forth in this patent, is a novel removable device used to prevent the accumulation of ice directly on the surface of a motor vehicle. By applying this device to a surface of a motor vehicle, it acts as a barrier to accumulating ice, provides a means for heating and hence melting the ice, and in turn facilitates the removal of the ice layer. The novelty of this invention is derived from its portability, removable nature, unique structural design, and ease of use. This innovative device improves upon some existing permanent de-icing technologies and effectively addresses the aforementioned public safety hazards.

Abstract: The present invention involves methods for the delivery of a plurality of parcels shipped by one or more shippers to a location via a carrier. Methods are disclosed for aggregating parcels shipped by one or more shippers for a single delivery to the location, thereby reducing the need for multiple deliveries to the same location (212, 214). In one method, the dates of the shipment of the parcels are coordinated such that the plurality of parcels may be delivered substantially simultaneously to the customer (212, 214). In another method, some parcels are delayed in their shipping route while others may be expedited such that the plurality of parcels are delivered substantially simultaneously to the location by the carrier (212, 214).
Patent CA-2574637-A1 (CA)
Inventor: FEINLEIB BORIS
IPC: F02B31/00
Filed: 2004-07-20
Abstract: Hydraulically driven pump-injector with controlling mechanism for internal combustion engines, primarily for diesel, distinguished via the fact that in the pump-injector body (1) above needle (9) additional cylindrical cavity (69) is made, in which locking piston (8) is mounted, resting upon needle (9), the diameter of said additional cavity and hence the piston diameter being selected on the basis of the formulae disclosed in the invention. Space (24) formed above the piston face is periodically connected through distribution channel (25) and valve (33) of the distributing device to the source of the actuating fluid and the drain tank, alternately. This ensures a decrease in the delay of the operation on the nozzle needle compared to the signal from the electronic control unit (travel of the valve of the distributing device), required for obtaining small time delays between the injections in multiphase injection, as well as increased stability of the idle running of the engine.  In accordance with the invention, penetration of gases from the combustion chamber to the fuel system and leaking of fuel into the combustion chamber when the nozzle needle ~hangs~, or ~freezes~ in it~s upper open position, are also prevented due to the fact that the fuel (actuating fluid) is supplied to the under-plunger cavity (19) through central channel (33) in the body, which stops locking piston (8) of needle (9) when the latter ~hangs~. The invention also allows for increasing average injection pressures and implementing ~rate shaping~.
