Title: Method and apparatus for predicting favored supplemental channel transmission slots using transmission power measurements of a fundamental channel
Inventor: HOLTZMAN JACK
IPC: H04B7/26
Filed: 2000-10-07
Granted: 2011-01-18
Abstract: A method and apparatus for selecting a favored transmission slot for communicating non-voice data in conjunction with a voice-data communication.  The slot, reflecting a favored power level and transmission rate for transmitting the non-voice data on a supplemental channel, is selected based upon the transmission power levels for voice-data transmitted by a base station to a remote station on a fundamental channel. The favored transmission slot is selected without the remote station messaging information to the base station concerning frequency channel or interference information for the supplemental channel.

Abstract: Herbicidal emulsion compositions containing an ethenylamide compound as a herbicidal active component and a dichloroacetamide compound as a chemical damage-relieving agent. These compositions suffer from neither degradation of the chemical damage-relieving agent nor sedimentation of crystals even after storing over a long time, thereby showing a high storage stability. Herbicidal emulsion compositions are prepared by adding amino alcohol and a polar non-aqueous solvent as a solvent to the ethenylamide compound and the dichloroacetamide compound.

Abstract: The present invention relates to a quick-disintegrating tablet in the bucc al cavity comprising a drug, a diluent, and a saccharide with a relatively lowe r melting point than the drug and the diluent, which is obtained by uniformly mixing the saccharide with a low melting point in the tablet so that a bridg e will be formed between said drug and/or said diluent particles by the product of melting and then solidification of this saccharide with a low melting point. Moreover, the present invention relates to a method of manufacturing a quick - disintegrating tablet in the buccal cavity comprising a drug, a diluent and a saccharide with a relatively lower melting point than the drug and the diluent, which comprises (a) the process whereby tablet starting materials including a drug, a diluent, and a saccharide with a relatively lower melting point than the drug and the diluent are molded under the low pressure necessary for retaining the shape of a tablet, (b) the process whereby the molded product obtained in process (a) is heated to at least the temperature at which this saccharide with a low melti ng point will melt, and (c) the process whereby the molded product obtained i n process (b) is cooled to at least the temperature at which the molten saccharide with a low melting point solidifies. The present invention presents a quick-disintegrating tablet in the buccal cavity that can be used for practical purposes in that it has almost the sam e properties as conventional oral pharmaceutical tablets, that is, it has sufficient tablet strength that it can be used with automatic unit dosing machines, and it is produced by conventional tableting machines, and a manufacturing method thereof. Moreover, the present invention presents a quick-disintegrating tablet in the buccal cavity which, in comparison to conventional quick-disintegrating tablets in the buccal cavity, has increased tablet strength and an improved friability without prolonging the disintegration time in the buccal cavity, and a manufacturing method thereof.

Abstract: A centrifugal separator for separating oil suspended in air and especially intended for use with aircraft engines includes a rota table chamber filled with a relatively rigid porous material and is driven by a hollow shaft. An inlet for the mixture of air and oil is provided in one end wall of the chamber and separate outlets for oil and air are provided in the outer and inner cylindrical walls of the chamber respectively. Oil droplets are formed in the rigid porous material and ejected out through the oil outlet under centrifugal forces while air relatively free from oil exits the air outlet and enters into the inside of the hollow shaft under the pressure difference. A  cut-away area is formed in the rigid porous material to facilitate ejection from the separator of the oil droplets formed in the porous material to clear the passages of the porous material and facilitate a continuous movement of the mixture of air and oil mist.

Abstract: A folding crate (10) or container is provided having a translating hinge arrangement (16) that allows a side wall (14) of the crate to freely translate in a vertical direction when rotated into a folded position. By allowing opposing side walls to move vertically relative to a bottom component (12) of the crate when folded, subsequent overlapping side walls will lay substantially flat and parallel to the bottom component when folded thereon.  This in turn allows the overall height of the crate to be reduced when in the folded position without requiring a specific side wall folding sequence.

Abstract: A cooking appliance includes a cooktop having at least one heating zone having first and second heating elements and a control element for setting a desired cooking temperature for the heating zone. When the control element is rotated in a first direction, only the first heating element will be activated and; when rotated in a second direction, both the first and second heating elements are activated. The control element includes a variable resistor that changes resistance as the control element is rotated through nearly 360° to alter the operational state of the heating element(s). A controller senses the change in resistance and determines in which direction the control element is rotated so as to activate the appropriate heating element(s).

Title: Fuel injection valve
Inventor: OVERSBY KEVIN
IPC: F02M51/06
Filed: 2004-07-09
Granted: 2006-11-14
Abstract: A fuel injection valve is provided for introducing a fuel into an engine and controlling fuel flow to reduce variability between injection events. The fuel injection valve employs an arrangement for a valve nozzle that cooperates with a valve needle. The valve needle and the valve body are shaped to cooperatively provide a constant flow area between the valve needle and the valve body. The constant flow area restricts flow through the nozzle so that mass flow rate is substantially constant for a range of valve needle movement within a predetermined range of needle movement. The method comprises commanding a valve needle to a position within the predetermined range of needle movement to reduce variability in the fuel mass flow rate, particularly when the engine is idling or operating under low load conditions. This improves injection consistency, thereby stabilizing engine operation, decreasing emissions, and increasing efficiency.

Granted: 2009-04-21
Abstract: This invention deals with an oxide/lubricant composite coating on lightweight materials (Al-, Mg and Ti-alloys) with multifunctionality in terms of high hardness, low friction, thermal barrier, and high corrosion resistance. The oxide coating matrix with certain porosity and roughness is synthesized by a plasma process in an electrolyte. The solid lubricant (graphite, MoS2) is incorporated into the oxide coating matrix said by rubbing the solid lubricant against the relatively porous and rough oxide coating surface during the coating growth. The composite coating finally consists of low frictional lubricant (graphite, MoS2) embedded in hard, low thermal conductive, and anti-corrosive oxide coating matrix. The present invention is particularly applicable for enhancement in wear and corrosion protections for lightweight metals and alloys used in said engine, transmission case, pulley, air condition compressor, and brake system.

Abstract: An illumination device simulates neon lighting and allows for emission of light in colors that cannot ordinarily be achieved by use of LEDs along through the incorporation of a light color conversion system into the illumination device. This light color conversion system comprises an intermediate light-transmitting medium (22) tinted with a predetermined combination of one or more fluorescent dyes. Light emitted from the light source (16) of the illumination device is directed into the intermediate light-transmitting medium (22) and interacts with the fluorescent dyes contained therein. This light is partially absorbed by each of the fluorescent dyes of the intermediate light-transmitting medium, and a lower-energy light is then emitted from each of the fluorescent dyes and into the light-receiving surface (12) of the waveguide. Thus, selection of appropriate combinations of dyes results in various colors being emitted from the illumination device.
