Title: Method and apparatus for objective assessment of in-ear device acoustical performance
Inventor: LAVILLE FREDERIC
IPC: H04R25/00
Filed: 2004-12-03
Abstract: A method and apparatus (10) for objectively assessing acoustical performance of an in-ear device (12) having a passageway (20) extending there through use a dual microphone probe (26) that removably engages the passageway (20). The acoustical performance of the in-ear device (12) is performed with the in-ear device (12) inserted into the ear canal (14) of the user and a reference sound source (24). A clip (36) holding the probe (26) in an acoustic near field of the sound source (24) permits real time calibration thereof. The method and apparatus (10) allow on-site and in-situ measurement of a predicted personal attenuation rating (P-PAR) of the device, a subject-fit re-insertion test, an acoustic seal test, a rating test, a stability and reliability test, as well as a protection test of the device (12) with an assessment of a filtered predicted exposure level (F-PEL) at the ear for a specific noise exposure level. The apparatus (10) may be simply housed along with the sound source (24) for in-field evaluation tests.

Abstract: A method of receiving and transporting solid waste includes providing a strong, disposable waste container and a disposable pallet for supporting the container when the latter is loaded with waste. After loading, both the pallet and the container can be lifted onto a rear transporting section of a truck. In one version, the pallet and container are placed on a rear end section of the truck and moved to a forward position by a conveyor system. A forklift unit can be used to lift and move the container and pallet. In another version, the truck has movable sidewall members that can be moved from an upright position to a second position that allows the pallet and container to be loaded from a longitudinal side of the truck.

Patent CA-2556752-A1 (CA)
Inventor: FENG BAINIAN
IPC: A61K31/427
Filed: 2005-02-22
Abstract: The present invention provides heterocyclic linker compounds useful for linking drug moieties to ligands. The compounds also include drug-ligand conjugates comprising a ligand capable of targeting a selected cell population, and a drug connected to the ligand by a heterocyclic linker moiety. The linker moiety comprises a peptide sequence that is a substrate for an intracellular enzyme, for example a cathepsin, that cleaves the peptide at an amide bond. The peptide further contains a self-immolating moiety which connects the drug and the protein peptide sequence. Upon cleavage of the peptide sequence by an intracellular enzyme the self~immolating moiety cleaves itself from the drug moiety such that the drag moiety is in an underivatized and active form.

Title: Seed tube for seed metering apparatus
Inventor: JOHNSON CHAD M
IPC: A01C7/08
Filed: 1999-01-25
Abstract: A seed tube for an agricultural implement having a seed metering mechanism for uniformly dispensing seeds. The seed tube defined an enclosed curved seed pathway extending between opposite ends of the tube. To promote control over the seeds passing through the tube, the tube has a smooth but decreasing cross-sectional configuration between the ingress and egress ends of the tube. The tube generally includes a front wall, a rear wall and a pair of side walls. The front wall is generally separated into an upper and lower portion. An opening in the front wall, which is provided to receive a monitoring device, is associated with the lower front wall portion. In addition, the lower front wall portion is stepped forward relative to the upper front wall portion. The enclosed seed pathway further includes a narrowed front edge extending in an upward direction from the egress end of the tube along some section of the front wall. The narrowed front edge enhances control over the seeds such that individual seeds passing through the tube and deposited to the ground have equidistant spacings between the seeds on the ground. The stepped forward arrangement for the lower front wall portion also allows a monitoring device to be used without disrupting the flow of seeds in the seed tube.

Patent CA-2574835-A1 (CA)
Title: Micro neutron detectors
Inventor: MCGREGOR DOUGLAS S
IPC: G21C3/32
Filed: 2005-07-28
Abstract: Micro neutron detectors include relatively small pockets of gas including a neutron reactive material. During use, under a voltage bias in a neutron environment, neutron interactions in the neutron reactive material are seen to occur. Ultimately, electron-ion pairs form and positive ions drift to a cathode and electrons to the anode. The motion of charges then produces an induced current that is sensed and measurable, thereby indicating the presence of neutrons. Preferred pocket volumes range from a few cubic microns to about 1200 mm3;neutron reactive materials include fissionable, fertile or fissile material (or combinations), such as 235U, 238U, 233U, 232Th, 239Pu, 10 B,6Li and 6LiF; gasses include one or more of argon, P-10, 3He, BF3, BF3, CO2, Xe, C4H10, CH4, C2H6, CF4, C3H8, dimethyl ether, C3H6 and C3H8.

Patent CA-2576410-A1 (CA)
Inventor: WOOLFE AUSTEN JOHN
IPC: A61K9/14
Filed: 2004-09-18
Abstract: The invention relates to particles for drug delivery by inhalation, said particles incorporating at least one active ingredient which is non-crystalline. The may be a plurality of active ingredients and moreover the outer surface of the particles may be substantially smooth. By providing non-crystalline particles with an outer smooth surface, a substantially accurate dose of active ingredient(s) can, in use of an inhalation device, be delivered each time the device is discharged, with a free flow and non-agglomeration of the particles. This is brought about by the smooth surface and the lack of a periodic ordered structure typical of a crystalline solid. The invention extends to an inhalation composition, and a pulmonary nasal inhalation device including such a composition.
