Patent CA-2325277-A1 (CA)
Inventor: LEE JENSEN
IPC: A46B11/00
Filed: 2000-11-16
Abstract: A brush head (25, Fig. 3), on the tip of a toothbrush sector (49, Fig.3), with bristle implants surrounding an orifice (26, Fig. 2) from where it is linked by an underlying tube (28, Fig. 2) to an accordion dentifrice cartridge (38, Fig. 2) via a mid-joint (39, Fig. 5). A needed amount of toothpaste can be infused onto the bristles bundles (22, Fig.  2) via the underlying tube by pushing the accordion bottom (40, Fig. 2). The brush head sector (49, Fig. 3) can be disposed at mid-joint (39, Fig. 5). Refill of toothpaste can be accomplished from a household tube by screwing on a suitable adapter (93, 94, Fig.7A and Fig. 7B). Additional designs: a switchable disposable brush-head plate (20, Fig. 9A) and a non-switchable brush-head plate (20A, Fig. 13B), mounting on a receptor (30, Fig.  10B), (30A, Fig. 13A) with an orifice (32, Fig. 12C), which links to an underlying tube (28, Fig. 10C), joining at one end with a male screw joint (48A, Fig. 10C) and a mid-joint (39, Fig. 5) on a handle, which houses an accordion cartridge (38, Fig. 6) for toothpaste. A motion of pushing forward or backward on the brush-head plate of a switchable brush-head plate will cause the brush-head orifice and the receptor orifice vertically connected or disconnected, thus opening and closing the thoroughfare of conveyance of dentifrice from the accordion dentifrice cartridge (38, Fig. 2) to the brush-head via an underlying tube (28, Fig. 2). All types of brush heads as well as a comb-brush head (102, Fig. 13E) are all interchangeable and disposable by screwing on and off at mid-joint (39, Fig. 5) or screw-joint (42, Fig. 11). Replenishment can be fulfilled by attaching an adapter to any domestic tube onto the mid-joint (39, Fig. 3) or the female screw joint (42, Fig. 11 ) into the cartridge (38, Fig. 11) or by replacing a new cartridge.      Refill at the non-switchable is via the rear inlet (82, Fig. 13C)

Title: Solid core vinyl screen door
Inventor: GREEN GUERRY E
IPC: E06B3/72
Filed: 2000-12-11
Abstract: A screen door made of foamed, closed-cell, solid-core polyvinyl chloride includes two rails and two stiles connected together to form a rectangular frame having an opening. A groove is milled into the frame around the opening. The screen that is to cover the opening is fastened to the frame by pressing it with a spline into the groove.  The rails and stiles are connected using dowels in addition to adhesives, or, alternatively, using screws and traditional mortise and tenon joints. Holes are drilled into the stiles and then screws are driven into the rails from within the holes. The holes are then filled with foamed plastic plugs over the screws. The screen door can be cut and trimmed at the job site to fit it to the particular door frame, removing up to about an inch from each edge.

Title: Navigation d'un helicoptere dote de commandes de vitesse au sol polaire limitee
Inventor: COTTON BRYAN S
IPC: B64C27/04
Filed: 1999-04-13
Abstract: On convertit l'enveloppe de caractéristiques de limitation de vitesse d'un hélicoptère en enveloppe de vitesse au sol en mettant en facteur la vitesse du vent et la direction. Une commande de vitesse au sol d'un hélicoptère télécommandé constitue une fonction de la distance franchissable vers la destination de l'hélicoptère. On peut calculer la fonction de façon à obtenir une commande de vitesse au sol nominale égale à une limite de commande de vitesse au sol nominale, ou alors la fonction peut être une fonction fixe afin que l'aéronef puisse glisser vers l'approche finale. Les cosinus et sinus de la direction de vol relative voulue de l'aéronef, qui est égale au relèvement vrai vers la destination moins le cap vrai de l'aéronef, sont utilisés pour mettre à l'échelle la commande de vitesse au sol en une commande de vitesse au sol longitudinale et une commande de vitesse au sol latérale. Si l'une des commandes de vitesse au sol dépasse une limite correspondante, on remet à l'échelle l'autre commande de vitesse au sol de sorte que l'addition des vecteurs des deux commandes permette d'obtenir un vol dans la direction voulue. Le dépassement de la commande gauche ou droite de vitesse au sol ainsi que la saturation du canal de pas cyclique gauche ou droit entraîne un mouvement de lacet du cap de l'aéronef dans la direction du dépassement de limite ou de la saturation de canal.

Title: Image coding/decoding method and recordind medium having program for this method recorded thereon
Inventor: MIURA TAKASHI
IPC: H04N19/60
Filed: 1999-06-03
Abstract: The data compression ratio is increased while the high quality of image of image data is maintained, and the calculation load in decoding is lightened.  In Figure 1(A), image data is divided into blocks, a DC image is formed of the average values of the blocks, the block average values are separated from pixel blocks, and a residual vector for each block is found. If the magnitude of the residual vector is the allowable value or more, an orthogonal base for approximation of the residual vector is found by adaptive orthogonal conversion using a nest of the DC image and coded. In Figure 1(B), if the residual vector is less than the allowable value, pixel data on 4x4 pixels of a block S is directly reproduced on the decoder side, instead of coding the orthogonal base, by a nonstep alternating current component predicting method based on five sets of DC image data on the block S and upper, lower, left, and right blocks (U, B, L, R) formed of block average values of 4x4 pixels.

The method of treatment consists of placing the tips of the lens-holders of the device consecutively at three or more contiguous sites of each orbtial roof for 2 to 4 minutes per site, twice weekly, for two months and for further periods as required. Patients are treated in a recumbent (or seated) position with eyes closed. No light is sent through the eyes. This treatment is used for essential hypertension, chronic pharyngitis, rheumatoid arthritis, allergies (especially respiratory), immunodeficiency arising from any cause, cancer, systemic lupus erythematosus, eczema, psoriasis, thyroid desease, viral syndromes and other pathologies involving neuro-immune-endocrine dysfunction. The device is equipped with (at least) two lens-holders, each with a filter transmitting wavelengths peaking at 350-400nm and 750-800nm (or with other appropriate specifications), quartz glass, biconvex lens of 50 dioptres (minimum) and low-powered medical bulb or other light source. In the hand-held model, the holders are mounted in a rectangular platic casing containing a printed circuit, pivot for positioning the holders, an output regulator with a digital display for voltage/mA. The input is 6V DC (battery model), 220V DC (mains model) and output is 0.5-3V DC  (variable); 50-300 mA.

Title: Brain-derived alkali-soluble immunoregulatory composition
Inventor: LINDSEY J WILLIAM
IPC: A61K35/30
Filed: 2000-02-04
Abstract: The current invention relates to an active factor present in homogenized bra in tissue which inhibits antigen-driven proliferation of lymphocytes in culture , but stimulates proliferation in response to most mitogens. The inhibitory activity can be destroyed by treatment with proteases or neuraminadase. The activity is in the insoluble fraction of the homogenate, but becomes soluble  in 0.04 M NaOH. After gel filtration chromatography of the NaOH soluble material, the suppressive activity is in the high molecular weight fraction which elutes in the void volume of the column. This fraction contains protei n and carbohydrate. The activity is not affected by neutralizing antibodies against regulatory cytokines, does not depend on Fas or FasL, and is not due  to the presence of gangliosides. These data suggest that a brain glycoprotei n which is either membrane-bound or part of the extracellular matrix has powerful immune regulatory effects in culture.
