Patent CA-2295068-A1 (CA)
Inventor: CITRON STEVEN D
IPC: B66F9/24
Filed: 1998-04-27
Abstract: A trailer personnel lift (20) with a level-sensing system (69). The levelsensing system (69) provides information to a level-indicator display (72) that indicates which outriggers (34) of the trailer personnel lift (20) need to be lowered. Upon lowering of the designated outriggers (34), the signal for the outrigger (34) changes so as to indicate that the outrigger (34) no longer needs lowering. The outriggers (34) are capable of locking into at least three positions, a first position (40A) in which the outrigger (34) extends substantially horizontal to the surface upon which the personnel lift (20) is to be located, a second position (48A) in which the outrigger (34) extends substantially vertically from the base, and a third position (46A) that is intermediate of the first and second positions, the third position being selected so that the outriggers (34) may be stabiliszed in the third position (46A) on an upward slope.

Abstract: A wheel for a vehicle comprises first and second wheel halves joined together, and a center plate being generally cross-shaped. Each wheel half has a disk portion and a rim continuing from the disk portion. The center plate is interposed between the disk portions and has a diameter smaller than an outside diameter of each of the disk portions. The first and second wheel halves and the center plate are unitarily connected together by means of a plurality of sockets each having a countersunk head and a cylindrical shank.

Patent CA-2303092-A1 (CA)
Inventor: KIM BYOUNG YOON
IPC: H04B10/29
Filed: 1998-08-19
Abstract: This invention relates to an optical amplifier capable of adjusting the gain curve to a desired shape. This invention also relates to a fiber light source capable of producing desired output spectrum. The method to use passive wavelength filters for the gain flattening of erbium doped fiber optical amplifier is well known.      However, the disadvantage with this method is that the gain curve varies depending on input optical signal power, gain level or changes in surrounding temperature. However, the optical amplifier of the present invention provides desired shapes of gain curves at various gain levels in spite of the reconfiguration of optical communication networks or the changes in driving conditions since the amplifier includes an active wavelength tunable filter and a gain detection system. The fiber light source of the present invention operates without external input light, producing spectrum-sliced output light from amplified spontaneous emission.

Abstract: A water heater is protectively packaged for shipment and handling by respectively inserting upper and lower end portions thereof in recesses in facing padded sides of upper and lower end assemblies having, on their opposite sides, spaced pluralities of parallel support rail members. The water heater and associated end assemblies are enclosed within a cardboard box having a vertical side wall portion spaced horizontally outwardly from the water heater, and vertically elongated reinforcing members extend along interior corner portions of the box between the upper and lower end assemblies and form therewith a vertical load path facilitating the stacking of water heaters packaged in this manner. The box has a closed upper end portion within which the upper end portion is disposed, and an open lower end portion having an opposing pair of downwardly projecting tabs which are removably secured to outer side portions of an outer pair of support rail members on the lower end assembly in a manner leaving the opposite ends of the support members exposed. By simply disconnecting the lower box tabs from their associated support rails, the box can be vertically removed to expose the water heater for field modification if necessary. The packaged water heater may be lifted using either a fork lift or a pair of conventional squeeze plates.

Title: Automated tooth shade analysis and matching system
Inventor: MABRITO CRAIG A
IPC: A61C19/10
Filed: 1999-05-05
Abstract: A patient's dental prosthesis (e.g., a prosthesis tooth, crown, veneer, or bridge) is made by acquiring an image (42) of the patient's teeth that contains black (54) and white (58) normalization references. These references are black, and white porcelain, for example, that allow software of the invention to determine absolute black and absolute white within the image. The image is then normalized in accordance with normalization references, which corrects the image for variations in lighting conditions and image source. The normalized image (60) is then standardized by matching the pixels of the normalized image (60) to selected shade standards (62). The dental prosthesis can then be manufactured by a lab technician by referring to the standardized image (66). The tooth shade analysis, and matching system is also applicable to direct restorations of natural teeth, such as repair of chipped or broken teeth.

Abstract: L'utilisation de la lignée cellulaire PC12 en tant que système modèle a permis d'identifier une série de transcrits induits par l'activation du récepteur de la leptine ou gp130. A partir d'études cinétiques de cellules PC12 indifférenciées, deux ensembles distincts de gènes ont pu être distingués: STAT-3, SOC-3, métallothionéine-II, sérine/thréonine kinase Fnk et homologue murin de MRF-1, gènes de la réponse précoce immédiate d'une part, Protéine  associée à la pancréatite I, Squalène Epoxidase, Uridinediphosphate Glucuronyl Transferase et Annexine VIII, gènes cibles à induction tardive d'autre part. Dans le dernier cas seulement, on a pu observer une forte co-stimulation par la forskoline, un activateur de l'adenylate cyclase. Deux autres transcrits codant pour la protéine induite par la leptine I (LIP-1) et pour la protéine induite par la leptine II (LIP-II) ont également été observés. LIP-II est un hortologue murin de la molécule d'adhésion cellulaire du syndrome de Down d'origine humaine (DS-CAM). Dans les deux cas, aucun effet co-stimulateur de la forskoline n'a été observé. Sur des cellules PC12 différenciées en phénotype neuronal par un traitement combiné  beta -NGF/forskoline, on a constaté par ailleurs que la protéine III associée à la pancréatite, la périphérine et la protéine Mx2 étaient régulées par la leptine. Enfin, à partir d'une expérience de ration diététique recommandée faisant intervenir de l'ARN m provenant de cellules PC12 induites par hyper-IL-6 ou par la leptine, on a constaté une régulation positive du gène Reg, autre membre de la famille des protéines associées à la pancréatite, et de HIP-1 par H-IL-6. STAT-3 et SOCS-3 avaient été observés auparavant in vivo dans la signalisation de la leptine. Cette invention démontre également que la leptine module l'expression in vivo des gènes MT-II, Fnk et de la protéine I associée à la pancréatite.
