Title: Safe opening can end and method of manufacturing
Inventor: DOUGLAS PETER M
IPC: B21D51/38
Filed: 1999-08-09
Abstract: A safe container end closure (20) includes an annular central lid portion (36), an annular peripheral lid portion (34), and a score line (32) having a v-shaped groove with a rounded nose portion therebetween. An opening tab (26) is secured to the central lid portion having a nose (54) positioned adjacent the score line (32) so that upon pivoting of the opening tab, the nose (54) causes a portion of the score line to sever. The central lid portion (36) includes an outwardly opening intermediate fold (44) and an inwardly opening bottom fold (48) that extends radially outwardly beyond the score line (32) so that the severed edge of the removed central lid portion is rendered safe. A nose spread (31) below the scoreline defines the extent that the severed edge of the central lid portion can move. The nose spread in the area of the nose of the opening tab is greater than at other areas.

Abstract: It is an object of the invention to improve the quality of images obtained by an X-ray detector.      A charge transport layer 13 mainly consisted of diantimony trisulfide, an X-ray detection layer 14 mainly consisted of amorphous selenium and a second electrode film 15 are formed in the same order on the surface of a first electrode film 12 provided on a substrate 11. A voltage whose polarity is positive at the first electrode film 12 and negative at the second electrode film 15 is applied, and the surface of the second electrode film 15 is irradiated with an X-ray. Then, carriers generated in the X-ray detection layer 14 are collected by the first and second electrode films . Since a diode whose anode is an X-ray detection layer 14 side and whose cathode is a charge transport layer 13 side is formed at the interface between the X-ray detection layer 14 and charge transport layer 13 of the X-ray detector 31, no hole is injected from the first electrode film 12 into the X-ray detection layer 14, which prevents any reduction of image quality.

Title: Als3 promoter in transformed plants
Inventor: MIKI BRIAN
IPC: C12N15/82
Filed: 1996-03-22
Abstract: The Brassica ALS3 promoter is operably linked to a foreign structural gene to provide high level, and generally constitutive or tissue general expression of the structural gene in transformed plants. The Brassica ALS3 promoter exhibits a non-tissue-preferred mode of expression at a level comparable to, and in some cases higher than, the widely used CaMV 35S promoter. Accordingly, DNA constructs comprising the Brassica ALS3 promoter operably linked to any number of different gene coding regions can be used for constitutive and tissue-general expression of the gene in transformed plants.      The Brassica ALS3 promoter is used to direct expression of agronomically important genes and selectable marker genes.

Filed: 2001-08-27
Abstract: A plastic material extruder combines the features of a generally flat rotatable disc and a generally flat opposed stator. At least one of the two is heated by heating elements. The two define a processing gap into which a hopper for feeding a plastic material mixture is discharged. The rotor and the stator develop a high shear force which further heats up the processed mixture in addition to the heating delivered by the heating elements. At the center of the disc/stator assembly, an axial force developing device such as a ram or a feed screw or screws is adapted to further compress and extrude a mixture of the thermoplastic components and thermosetting components, the latter being comprised of crumbled pieces of used tires. The extruder is shown in two embodiments, one injecting the processed alloy into a mold, the other producing pellets of the processed alloy.

Title: Media filter cabinet for gas furnace
Inventor: LANG ROBERT A II
IPC: B01D46/00
Filed: 2001-10-09
Abstract: A media filter cabinet for a gas furnace is sized to accept a high-efficiency media filter while being easily adaptable to accept a standard size filter. A  perforated duct flange on one side of the cabinet permits ease of installation since the flange can be bent at 90 or 180 degrees along the perforations, or removed, depending on the type of duct the cabinet is installed with. The cabinet is adapted to fit a standard filter by using a removable bracket and a wire to retain the standard filter within the cabinet. With the removal of a front door and a back side of the cabinet, the cabinet collapses to diminish its shipping size. In one embodiment, the cabinet is in kit form which is easily assembled.

Patent CA-2359439-A1 (CA)
Title: Ultrasonic surgical system
Inventor: DONOFRIO WILLIAM T
IPC: A61B17/3211
Filed: 2001-10-17
Abstract: An ultrasonic surgical system utilizes a digital control system to generate ultrasonic drive current for transducers that are located in a hand piece and are attached to a surgical scalpel or blade in the hand piece so as to vibrate the blade in response to the current. The digital control includes a digital signal processor (DSP) or microprocessor; a direct digital synthesis (DDS) device; a phase detection logic scheme, a control algorithm for seeking and maintaining resonance frequency; and design scheme that allows to regulate current, voltage, and power delivered to an ultrasonic thereby a device. Such system allows the power versus load output curve to be tailored to a specific hand piece, which improves efficiency and reduces heat. Further, the components of the digital system are much less sensitive to temperature variations, thereby allowing it to operate with narrow as needed frequency range around the desired resonance in order to avoid excitation of other resonances. Also, the digital system provides increased flexibility in locating the resonance frequency of the blade and running diagnostic tests. The start of a user initiated diagnostic test that requires movement of the blade is caused by operating two of the system switches, which guards against accidental operation of the blade which could be harmful if in contact with tissue and also generate false diagnostic results. In addition, the system has interlock with an Electrosurgical unit so that it is not effected by the electromagnetic interference generated by that unit.
