Abstract: A portable sound recording device includes a microphone, a speaker and recording/playback circuitry connected to the microphone and speaker. The recording/playback circuitry includes a recording medium such as a removable solid state memory card. A control circuit controls operation of the recording/playback circuitry on the basis of input signals generated by a user via an operating switch array. The switch array includes a record switch. If the record switch is actuated for only a brief period of time, a record-lock mode of operation is implemented. If the record switch is actuated for a longer period of time, a momentary-record mode is entered which lasts only as long as the record switch remains in an actuated position.

Abstract: A sound recording system includes a hand microphone with a plurality of operation switches mounted on the hand microphone. The switches include a record switch. The system also includes a sound recording device which is connected by a signal path to the hand microphone and records sound information generated at the hand microphone. Control circuitry included in the hand microphone and/or in the sound recording device controls operation of the sound recording device on the basis of input signals generated by the user via the operating switch array. If the record switch is actuated for only a brief period of time, a record-lock mode of operation is implemented. If the record switch is actuated for a longer period of time, a momentary-record mode is entered which lasts only as long as the record switch remains in an actuated position.

Abstract: A central dictation system includes a central server computer and a plurality of voice input stations connected to the server computer. Speaker-dependent speech recognition capabilities are provided at each voice input station, and any authorized user may use any station. When a user logs on to one of the stations, acoustic reference files to be used in recognizing the speech of the user are downloaded from the server to the station onto which the user has logged on. The down-loaded acoustic reference files are used to perform the speech recognition at the voice input station. A high bandwidth signal generated at the voice input station and used for speech recognition processing is transcoded at the input station to form a low bandwidth speech signal. The low bandwidth speech signal and the text document resulting from the speech recognition process are uploaded to the server computer.

Abstract: A rotary stepped storage and display unit is placed on shelves in cabinets and other locations above eye level to store and display items such as spice jars etc. on a stepped surface so that items can be seen easily from below. Preferably, the device comprises a circular stepped pyramid on a rotary base. The device is provided in separate sections which are small enough to pass through the access opening to corner cupboards in kitchens or similar places where the access openings are considerably smaller than the inside dimensions of the cupboard. Easy-to-use snap fasteners are integral with the sections and are used to fasten the sections together inside the cabinet to form a structure which is too large to pass through the access opening but utilizes the space efficiently in the cabinet. The device either can rotate on its own rotary base, or can be mounted on one or more of the upper shelves of a series of rotary shelves mounted to rotate on a vertical axle in a corner or similar cupboard.

Abstract: Anti-static cleanroom products having a coating of conductive polymeric particulates which decreases the surface resistivity of the products. Preferably, the particulates are pyrrole polymers. The anti-static properties are achieved by depositing conductive polymer particles onto the non-conductive substrate surface. The anti-static products include cleanroom wipers, stationery products (notebooks and writing instruments), garments and swabs (polyurethane foam tipped). The cleanroom stationery products include notebooks comprising polyethylene impregnated with silica. The invention also includes anti-static plastic gloves.

Abstract: The device sprays a mist of cleaning fluid onto the record medium—e.g., motion picture film—and wipes it off, preferably with a soft material such as velvet. Then, the film is dried with air, including thin air jets to spread the liquid evenly, and heated, ionized air. The device has a closed housing and air in the housing is evacuated and sent to a still to recover much of the cleaning liquid and prevent its escape into the atmosphere.

Abstract: A cleaning sheet with a tacky surface coating is used to clean feed rollers in copying machines or similar equipment and similarly-coated cloths are used for the removal of particles from other surfaces to be cleaned. The cleaning articles are made by printing the tacky material on sheet material such as paper or cloth. Relatively thick layers of tacky material are applied quickly and economically by the use of a multi-stage printing press which builds up a thick layer from a plurality of thin layers.

Abstract: A turntable storage device which has a turntable and a plurality of storage containers for condiments and other granular materials. The turntable has a base member and a platform that is removably attachable to the base and rotatable on the base member. The base member has an upwardly extending hollow post. The containers are attachable to the turntable by mating projections and receptacles. The turntable storage device is convertible. It is provided with a mounting hub for selectively attaching and removing either a handle or a hanging support member. The hanging support member is adaptable to hang one or more turntables from a shelf, if desired. The support member also is shaped to fit into the hollow post of another turntable, whereby two turntables can be stacked on top of the one another. In one embodiment, a rotary measuring dispenser is mounted in each container for dispensing predetermined quantities of material.

Abstract: The ventilator system and method use a isolating heat exchanger to selectively transfer heat between exhaust air leaving an enclosed space and outside air entering the enclosed space. The system operates in three basic modes, under the control of a microprocessor-based controller which is responsive to the temperatures inside and outside of the enclosed space. In the heating mode, heat is transferred from the exhaust air to the outside air when the enclosed space requires heating. In the cooling mode, heat is transferred from the outside air to the exhaust air when the outside air temperature is higher than that in the enclosed space. In the supplemental cooling mode, heat transfer between the exhaust and outside air is reduced or eliminated when the outside air temperature is below the desired temperature in the enclosed space and cooling is required. In the heating mode, the heat exchanger is selectively heated when necessary to defrost it.

Abstract: The container is adapted to be releasably secured to a rotatable turntable. It has a pie-shaped cross section, with a recess in the bottom to receive a projection to hold it in place on the turntable. Another projection projects laterally from the narrow end of the container to mate with a receptacle on the turntable to prevent the container from being tipped off of the turntable. The container has a sloping hinged cover for a large opening on the top, and a hinged cover for a small shaker opening in the top. In one embodiment, the container has a dispensing opening in the bottom and a rotary dispenser operable from outside the container for dispensing pre-measured quantities of materials through the bottom opening.

Abstract: A dehumidifier unit for pre-conditioning air delivered to a multiplicity of separate refrigeration air conditioner units and especially ductless systems where the compressor-condenser unit is separate from the fan-coil unit, and assisted by heat pipe transfer of heat from air dehumidified through a desiccant wheel and by heat of compression from the condenser of one compressor-condenser unit, and with a heater to maintain the temperature of regeneration air through the wheel, one dehumidifier unit pre-conditioning air for a multiplicity of refrigeration air conditioners or fan-coil units.
