Title: Insecticide and insect repellant compositions
Inventor: JAMES LYNN SUE
IPC: A61K31/16
Filed: 1994-08-18
Granted: 2004-08-17
Abstract: A non-toxic, environmentally safe and easily employable insecticide and insect repellant is achieved by providing an aqueous composition incorporating ethanolamine based compounds, either independently or in combination with the ethanolamine based compounds being selected from both simple compounds and conjugated compounds. In one preferred embodiment, a highly effective composition is attained for safe, effective, direct topical application to humans and animals by employing between about 10% and 70% by volume of the entire composition of the ethanol-amine-based compound. In alternate preferred embodiments, the insecticide is formulated for application to plants, trees, crops, and other vegetation to provide a composition which effectively controls bothersome insects, while being completely safe and non-injurious to the plant, tree, or crop, as welt as to the flowers or fruit thereof. In addition, the compositions of this invention are completely biodegradable, and are safe to the environment and water supplies.

Abstract: A synthetic wood meal in which a thermoplastic resin material of 25 to 80 wt% is mixed with a cellulose crushed material of 20 to 75 wt% that lies in the moisture content of within 15 wt% and the mean particle diameter of 20 mesh or less, the mixed material is kneaded so as to be set to gel, and the kneaded material is cooled and pulverized and regulated to a size that lies in a particle diameter of 10 mm or less. Then, the synthetic wood meal as the cellulose crushed material is mixed in at the rate of 20 to 75 wt% to the resin material, the mixed material is kneaded by heating and squeezed by a screw or screws of an extruding die 78 in an extruder. When the extruding material 79 passes through the inner wall surface of the extruding die 78, which lines with a fluororesin sheet 24 thereon, the cellulose crushed material included in the extruding material is smoothly extruded without being subjected to large resisting force, so that a molded article 29 is molded for a product having an uniform and high density and a predetermined thickness, while applying resisting force against squeezing force given from the extruder to the molded article 29 by using a braking means, thus molding a synthetic wood board having more uniform and higher density.

Title: User refillable ink jet cartridge and method for making said cartridge
Inventor: ONTAWAR SUSAN P
IPC: B41J2/175
Filed: 1993-11-12
Granted: 1996-10-08
Abstract: A non-refillable ink jet cartridge is rendered user refillable in a convenient manner. Hewlett-Packard ink jet cartridge #51626A is modified by sealing the vent hole at the base of the cartridge with a pressure sensitive adhesive tape, and removing the air tight ink fill plug at the top of the cartridge. After refilling with ink, a bellows type inflator bottle is used to inflate bladders within the cartridge making use of an opening in the cartridge. The ink fill opening is re-sealed either immediately before or just after the bladders are inflated, and the inflator bottle is then removed which releases the air pressure in the bladders causing the bladders to deflate. The deflated bladders cause an area of reduced air pressure to develop over the ink fill level, which prevents the ink from leaking out of the cartridge when the pressure sensitive adhesive tape covering the vent hole at the base of the cartridge is removed.

Abstract: A differential/absolute value image is derived by calculating an absolute value of each pixel in an image produced by subtracting a background image from an input image.  A mean value and a variance of a pixel in the differential/absolute value image are calculated from the levels of pixels included in a small region on the differential/absolute value image which has the pixel located at the center thereof.  The calculated mean value and variance of the pixel are used to distinguish whether the pixel is a pixel included in a moving object existing region, a background region, or an input image sudden change region.  A method of updating the background image is changed in accordance with whether the pixel is a pixel included in the moving object existing region, the background region, or the input image sudden change region.

Abstract: An appliance timer has features to facilitate automated assembly or manual assembly. A timer housing base accepts timer components from two directions, and installation of components in either direction is along a straight axis. A motor in the tinner engages a gear train which runs a drive cam. The drive cam impartsmotion to a camstrack which then engages timer blade switches, and the blade switches operate the appliance. A subinterval is also supplied on the timer to allow periodic operation of a switch without the use of the camstack The timer also features a quiet manual advance which removes the blade switches from communication with the camstack to allow an operator to select various timer programs without any of the clicking noises that are usually associated with timer programs selection. Furthermore, a detent slider is positioned in communication with the camstack to provide a tactile feel for the operator of the timer when selecting between various timer programs.

Abstract: The present invention provides an animal waterer having an animal alignment guide attached to the water supply line near the juncture of the terminal conduit and the nipple valve. The guide includes an interior portion attached to the water supply line and a pair of guide wings extending out on opposite lateral sides of the nipple valve about the same distance as the trigger of the nipple valve. The vertical position of the nipple valve is adjustable so that the nipple valve can be easily and quickly positioned at the most efficient drinking height for the size of animal being watered. One embodiment of the waterer includes a waterer fed by a flexible feed line, and supported by a chain to freely swing at an elevation of about two inches above the backs of the animals. A  second swinging embodiment includes a suspension bracket which extends up from the vertical axis of the supply line for connection with a chain so that the waterer will hang straight. Also, this second embodiment uses a single triangular bend in the terminal conduit so that the terminal conduit is inclined downwardly and has no horizontal sections. This configuration eliminates the buildup of excess galvanizing material in the interior of the terminal conduit when the unit is submersed in and withdrawn from the vat of zinc galvanizing material during the plating process.

Abstract: Cette invention concerne un procédé de transmission de données permettant d'effectuer une transmission des données de haute qualité et à vitesse variable tout effectuant une discrimination de vitesse avec plus de sûreté. Cette invention concerne également un système de transmission de données, un émetteur ainsi qu'un récepteur. D'après ce procédé de transmission à vitesse variable, des données de transmission de longueur variable sont émises en disposant les données dans des trames qui possèdent chacune une longueur temporelle fixe. Le côté émetteur va émettre des données utilisateur en ajoutant un code de détection d'erreurs aux données. Le côté récepteur va effectuer un décodage de Viterbi jusqu'à la position du bit final des données de trame transmises, ceci en évaluant successivement la position du bit final. Ce procédé fait appel à la probabilité maximale de plusieurs séquences de données décodées potentielles, ainsi qu'à la probabilité d'une séquence de données décodée obtenue à la fin d'un processus de décodage. Lorsque la différence entre ces probabilités tombe dans une plage prédéterminée, et qu'il a été confirmé qu'un code de détection calculé coïncide, par comparaison, avec un code de détection d'erreurs reçu, les données transmises sont alors décodées en établissant que la position du bit final évaluée est bien la position du bit final des données de trame transmises.
