Patent CA-2273490-A1 (CA)
Inventor: ST LOUIS ROBERT MAURICE
IPC: D06F58/04
Filed: 1999-05-27
Abstract: There is disclosed a clothes dryer having a rear end head with axially spaced apart apertures through which air may enter into the dryer drum through a diffuser wall mounted to the inside of the drum end head.    The apertures in the end head have an air flow deflection shield integrally formed therewith. The air flow deflection shield extends radially across the apertures in the end head, is recessed from the rear end head and is spaced from the diffuser wall. Advantage is found with the use of such an air flow deflection shield because it permits for the apertures in the rear head to be of sufficient size to permit satisfactory air flow into the dryer drum while deflecting the air away from potential warm spots generated through and on the surface of the diffuser wall that would otherwise be in direct immediate air flow impingement with the apertures in the end head.

Title: Collarless circularly magnetized torque transducer and method for measuring torque using same
Inventor: GARSHELIS IVAN J
IPC: G01L3/10
Filed: 1998-10-21
Abstract: A magnetoelastic torque sensor (2) for providing an output signal (24) indicative of the torque applied to a member about an axially extending axis of the member (11), comprising, a first magnetoelastically active region in the member, the region being magnetically polarized in a single circumferential direction and possessing sufficient magnetic anisotropy to return the magnetization in the region, following the application of torque to the member, to the single circumferential direction when the applied torque is reduced to zero, whereby the magnetoelastically active region produces a magnetic field varying with the torque. Magnetic field sensors are mounted proximate to the magnetoelastically active region (ABC) and oriented with respect thereto to sense the magnitude of the magnetic field at the sensors (6) and provide the output signal in response thereto (24). At least the magnetoelastically active region of the member is formed of a polycrystalline material wherein at least 50 % of the distribution of local magnetizations lie within a 90 ~C quadrant symmetrically disposed around the single circular direction and having a coercivity sufficiently high that the field arising from the magnetoelastically active region does not magnetize regions of the member proximate to the magnetoelastically active region to give rise to parasitic magnetic fields which are of sufficient strength to destroy the usefulness, for torque sensing purposes, of the net magnetic field seen by the magnetic field sensor means.

Title: Seismic data acquisition and processing using non-linear distortion in a groundforce signal
Inventor: BARR FREDERICK J
IPC: G06F17/10
Filed: 1998-11-11
Abstract: In a seismic data acquisition system that uses a vibratory source an actual groundforce signal is recorded. This groundforce signal includes, in addition to a reference sweep signal, noise including harmonic distortion. This recorded groundforce signal is used to derive a filter that is used for filtering seismic data that has been generated by the source and reflected by subsurface reflectors to suitable detectors at the surface. The filter is derived by dividing, in the frequency domain, a short duration wavelet by the time derivative of the ground force signal.

Title: Clippers for fingernails
Inventor: REISWIG GARY J
IPC: A45D29/02
Filed: 1998-03-11
Abstract: The clipper (10) of the present invention includes a clipper handle (12) with a first component (14) and a second component (16) which are moveable with respect to each other. A nail holder (18) extends from the clipper handle (12), the nail holder (18) having a curved cross section. A slot (20) for receiving the fingernail to be clipped is defined in the nail holder (18). A  blade (22) is slidably mounted with respect to the nail holder (18), and has a cross section which corresponds to the curved cross section of the nail holder (18). The blade (22) terminates in a blade edge (24). The nail holder (18) and the blade (22) are each mounted to one of the first and second components (14, 16). Therefore, when relative movement is effected between the handle components (14, 16), a sliding action takes place between the nail holder (18) and the blade (22) to cut a nail which has been inserted into the slot (20) in the nail holder (18). The curved cross section of the nail holder (18) and the blade (22) ensures that the nail will be cut in an ideally rounded configuration.

IPC: A61N7/00
Filed: 1998-04-16
Abstract: On décrit des dispositifs et des procédés d'application d'ultrasons qui servent à cicatriser le sternum d'un patient. Le procédé consiste à positionner un dispositif d'application d'ultrasons à proximité d'un sternum présentant des parties affrontées, puis à appliquer les ultrasons sur lesdites parties en vue d'accélérer la cicatrisation. Le dispositif d'application d'ultrasons inclut un transducteur pour générer les ultrasons, et un support pour positionner le transducteur à proximité du sternum. Une lentille concave peut être disposée entre le transducteur et le sternum pour faire diverger acoustiquement les ultrasons afin d'en inonder le sternum. Plusieurs transducteurs peuvent être logés dans une série d'évidements ménagés sur le support, le long d'une distance longitudinale du sternum. Le dispositif peut inclure un anneau qu'on positionne et attache autour du cou du patient. Cet anneau peut être tissé en cravate et/ou incorporé dans une cravate. Le dispositif peut être équipé d'une bande métallique réagissant à des signaux provenant du transducteur pour générer des ultrasons à appliquer au sternum. Cette bande métallique peut être implantée à l'intérieur du patient, à un emplacement sensiblement adjacent au sternum. Le dispositif d'application d'ultrasons peut également fonctionner conjointement avec une maille qu'on implante à l'intérieur du patient, à un emplacement sensiblement adjacent au sternum.

Title: Procede d'identification de ligands pour recepteurs d'hormones nucleaires
Inventor: EVANS RONALD M
IPC: G01N33/566
Filed: 1998-04-01
Abstract: Les acides gras et leurs dérivés sont des métabolites cellulaires essentiels dont les concentrations exigent une régulation rigoureuse, nécessitant la présence de circuits régulateurs capables de déceler les variations des taux d'acides gras. De fait, le récepteur activé de la prolifération des peroxysomes .alpha. (PPAR.alpha.) régule l'homéostasie lipidique et est activé de manière transcriptionnelle par une série de composés de type lipidique. La clarté n'est toujours pas faite sur les modalités d'activation d'un récepteur unique par de tels composés structurellement divers. L'invention concerne des analyses à base de conformation qui criblent les activateurs pour détecter leur capacité de liaison avec les PPAR (c'est-à-dire, PPAR.alpha., PPAR.delta. et PPAR.gamma.) et leur aptitude à induire la liaison ADN. Il apparaît ici que certains acides gras spécifiques, éicosanoïdes et agents lipomodulateurs sont des ligands pour les PPAR.alpha., les PPAR.delta. et/ou les PPAR.gamma.. Etant donné que les variations des taux d'acides gras sont associées à l'obésité, l'athérosclérose, l'hypertension et le diabète, les PPAR peuvent tenir lieu de capteurs moléculaires jouant un rôle central dans l'évolution et le traitement de tels troubles du métabolisme.

Filed: 1998-07-08
Abstract: An optical device includes a waveguiding configuration (21) and an electrical capacitive configuration wherein the capacitive configuration comprises glass electrode region(s) (13) and glass dielectric region(s) (14) with electrical leads (19, 20) e.g. metallic conductors, for applying electrical control signals to the electrode region(s) (13). The preferred metals for the conductors are Ni, Ti and Au. The waveguiding structural (21) is configured so that the fields associated with optical signals propagating therein interact with region(s) (13). During the use of the device control signals are applied to the region(s) (13) by means of the electrical leads (19, 20). The control signals have the effect that temporary electrical fields are applied to the region(s) (13). The fields change the optical properties of the region(s) (13) and this affects the propagation of the optical signals. The device can either be produced in planar or fibre configurations.
