Abstract: DISPLAY ARRANGEMENT FOR COOKING APPLIANCE WITH POWER CONTROL            USING HEATER ENERGY COUNTER              ABSTRACT OF THE DISCLOSURE         A display arrangement for a cooking appliance using a heater energy counter based power control system which provides a user discernible signal signifying that the appliance heating element has reached the steady state temperature associated with the user selected power setting.  The heater energy counter is selectively incremented or decremented at a rate in accordance with the selected power setting such that the count rate is approximately proportional to the rate of increase or decrease respectively of the temperature of the heating element for the power setting selected.  When so incremented and decremented the count of the counter provides an approximation of the actual heating element temperature.  The display arrangement generates a user discernible signal  when the count of the heater energy counter indicates that the associated heating element has approximately reached the steady state temperature for the selected power setting. In the illustrative embodiment the display comprises an LED array associated with each heating element.  Each array is energized to provide a pattern representative of the power setting selected by the user for its associated heating element.  When the count of the heater energy counter indicates that the steady state temperature for the selected setting has been reached, the display flickers for a predetenmined period to signify to the user that the steady state condition has been reached.

Abstract: Abstract In a tool for cleaning paint brushes and rollers, manual work is applied in order to spin the paint brush or roller, allowing centrifugal force to clean and dry them.  In this invention the spiral spindle and handle assembly used for manual operation is replaced by a shaft which can be inserted into an electrical hand drill.  This improvement allows the drill to power the cleaning tool, which in turn cleans the brushes and rollers faster and better.

Title: Removal of chlorine-based contaminants from materials contaminated with same
Inventor: KEANE JAMES
IPC: B08B3/10
Filed: 1985-11-26
Granted: 1989-09-26
Abstract: The separation of a chlorine-based contaminant from a surface of a substrate covered with same is effected by dissolving the contaminant in a first solvent to form a solution thereof and admixing a further solution consisting of a membrane-like material forming component derived from mineral crude oil, bitumen or amphipathic lipids in a second solvent selected from the group consisting of halogenated hydrocarbons and p-xylene, the second solvent being miscible with the first solvent and capable of forming in the presence of water and the membrane-like material forming component an interfacial membrane-like material which has a water side and is impermeable to the contaminant. Water is then intimately contacted with the surface of the substrate so as to cause the membrane-like material to form at the surface of the substrate with the water side oriented toward the surface while the water wets the surface and spreads thereover, the membrane-like material incorporating during its formation the contaminant and mixture of solvents adjacent the surface, and the water displacing the membrane-like material away from the surface as it is being formed thereacross to thereby separate the contaminant and mixture of solvents from the surface and cover the surface with a layer of water. The invention is particularly useful for the decontamination of dioxin contaminated soils.

Abstract: POLYARYLENE POLYETHER MADE USING MIXED BASE SYSTEM       Abstract of the Disclosure Polyarylene polyethers, made by a process comprising reacting a dihydroxy compound and strong and weak bases in a liquid reaction medium at 100-200°C  to form a double salt and then reacting the double salt with a slight molar excess of dihalobenzenoid compound bearing two replaceable halogens, are disclosed.  The process reliably produces halogen-terminated polyarylene polyethers of select degrees of polymerization and desirable correspondence between weight and number average molecular weights.  In subsequent steps amine-terminated polyarylene polyethers are made using the strong and weak bases.          The resulting amine-terminated polyethers have a low, select degree of polymerization, desirable correspondence between weight and number average molecular weights and high level of amine-termination.  The amine-terminated polyarylene polyether sulfones of this invention have use in making tough epoxy thermosets.

Abstract: ABSTRACT: Charge transfer device.           The invention relates to a charge-coupled device, in which the reset transistor of the output is clocked - with a positive threshold voltage - by a maximum voltage equal to the supply voltage VDD. The drain (14) of the reset transistor is adjusted by means of an auxiliary transistor (T1) controlled by a current source (T2) and having the same threshold voltage, whose gate (21) is applied to VDD and whose source (22) is connected to the drain (14) of the reset transistor. Due to the fact that the maximum gate voltage is equal to VDD, additional voltage sources, such as charge pumps, for generating voltages higher than VDD are superfluous.   Fig. 3.

Abstract: METHOD AND APPARATUS FOR OPTICALLY DETERMINING DEFECTS IN A SEMICONDUCTOR MATERIAL     Abstract Individual defects in or near the surface of a silicon wafer are detected by directing a time-modulated laser beam, having an energy level above the bandgap energy of the silicon material, towards the wafer.  The beam is focused to a one to two micron spot on the wafer surface to photoexcite (i.e., pump) a high density of electrons and holes which changes the infrared reflectance in the area of the pumped spot.  A probe beam of infrared radiation is directed at the surface (0.126  square mm in area) of the substrate and at a small angle thereto and the reflection thereof monitored by a detector.  The pumped spot is raster scanned within the area of the probe beam spot.  The detector detects only that portion of the intensity of reflected probe beam that is modulated by the pump beam frequency to create a video display having a high spatial resolution showing individual defects.

When the organic material is a polymerizable monomer the dispersion prepared is converted to a polymer dispersion. In the first step swellable oligomer or oligomer-polymer particles are prepared by (a) dispersing an aqueous mixture containing an oil-soluble initiator or a solution of an oil soluble initiator in an organic solvent, and then swelling the dispersed initiator-containing droplets with monomer and effecting polymerization, or (b) swelling polymer particles in aqueous dispersion with vinyl monomer and an oil-soluble initiator and effecting polymerization, the ratio between initiator and monomer used being so high that in the polymerization an oligomer having a degree of polymerization of 5-200 is formed. In the second step, optionally after dilution with water and addition of emulsifier, the organic material is added which has a solubility in water of >10, preferably >100 times higher than that of the oligomer and which diffuses through the aqueous phase and swells the oligomer or oligomer-polymer particles in a ratio by volume of >20:1. When the organic material is a polymerizable monomer, initiator is also added in the second step, and polymerization is effected.
