Abstract: An exhaust particle and particulate containment system for a coffee roaster comprises a filter chamber for exhaust coffee roasting by-products including chaff and smoke particulates and oils is comprised of a screen for separating chaff from the exhaust coffee roasting by-product effluent and a filter for containing chaff and removing smoke particulates and oils when the screen is in a closed position.

Abstract: An exhaust particle and particulate containment system for a coffee roaster includes an exhaust duct for carrying exhaust coffee roasting by-products including air, gasses, smoke and chaff from the coffee roaster to a porous medium for separating chaff from the exhaust coffee roasting by-product flow and a filter for removing smoke particles from the exhaust coffee roasting by-product flow which passes through the porous medium.

Abstract: A coffee roaster which roasts coffee beans in a removable oven chamber employing both radiant and convection heating techniques while the beans are continually intermixed in a fluidized bed rotating in the horizontal plane. Roaster control means are provided to terminate the roasting process by quenching the beans and oven chamber with relative cool air while maintaining the beans in a fluidized bed to avoid scorching or further roasting by the residual heat of the coffee bean mass. The oven chamber is provided with an insulated handle to facilitate its removal from the heating chamber for dispensing roasted coffee beans. It includes an upper transparent section through which the roasted charge of beans may be viewed to thereby facilitate poring beans from the removed chamber.

Abstract: A method and apparatus for conditioning a blink reaction of a person using a computer terminal display. Blinking is selectively triggered by a macro shift in the dominant object viewed by the person or a macro tactile event simultaneously with a shift in a non-dominant object viewed by the person or a micro tactile event. The macro shift may be in the form of foreground/background reversal, display color changes, blank screen, etc. caused by hardware switching device or programed ANSI escape sequence changes. The non-dominant object may be a cursor, the last character typed, etc. The macro or micro tactile event may be a vibration, sound, puff of air, etc. The person is conditioned to blink in response to the non-dominant visual cue or micro tactile event by the association between the non-dominant or micro event and the dominant or macro event which causes involuntary blinking.

Abstract: A method and apparatus for triggering the reflex blink reaction of a person using a computer terminal display. Blinking is triggered by a macro shift in the dominant object viewed by the person. The macro shift may be in the form of foreground/background reversal, display color changes, blank screen, etc. caused by hardware switching means or programed ANSI escape sequence changes.

Abstract: A method and apparatus for protecting a camera or other apparatus from a water environment with a flexible, pressure compensated bag-like housing which is maintained at a slight positive pressure. The housing is larger than its contents to permit the contents to be moved relative to at least one wall to activate controls by frictional engagement between the wall and control during the relative movement. The housing may be configured as a merchandising container for the contents.

Abstract: A interactive value-added telecommunications system including automatic billing at a value-added rate controllable in real time is realized through in-place network carrier system utilities including multiparty switching which verify a calling party by a telephone number, and optionally a PIN number, and provides for calling party authorization of billing at a rate established by the called party. The system enables a method for conducting a business wherein a party calls for a service or product, is identified via one or two separate code sequences, requests a service or product from the called provider who establishes a rate for compliance. The caller authorizes and initiates the established charge to an account associated with one of said code sequences which preferably is a telephone number associated with a credit or debit account by completing a third-party call to a designated value-added number.

Abstract: A method and apparatus for pressure compensating an under water housing which includes a tubular structure sealed around a hole in the housing dimensioned so that the mouth of an inflated balloon will form a secure seal there on so that the housing may be pressure compensated by blowing up the balloon and sealing the balloon mouth around the tube.

Abstract: A method and apparatus for pressure compensating an underwater housing by blowing up a balloon and sealing the balloon mouth around a conduit to pneumatically connect the balloon to the interior of the housing. The balloon is configured to change its appearance either structurally or via indicia to provide a variable indication as to what depth it will provide compensating air. The indication varies in response to the amount the balloon stretches to accommodate the air forced into the balloon as it is blown up.

Abstract: An apparatus for extending the depth range of an underwater pressure hull such as an underwater camera body by providing a means responsive to ambient pressure for equalizing the pressure between the hull and its environment.

Abstract: A container for adapting a device such as a video camera, camera, strobe light, etc. for underwater operation by providing a flexible, waterproof container and a means to pressurize the container prior to or during immersion. In numerous embodiments, the apparatus includes a pressurizing means responsive to ambient water pressure.

Abstract: An orientation system adapted to be mounted within a vehicle, comprising a display including a rotational heading indicating compass card fabricated from an image retaining electronic display panel responsive to bearing data signals.

Abstract: A coated glass glazing system is presented including a transparent glass substrate having one surface coated with a radiation absorptive film which is overcoated with a radiation reflective film by a technique which renders the radiation reflective film radiation absorptive at the surface contacting the radiating absorptive film. The coated glass system is used as glazing for storm windows which are adapted to be reversible so that the radiation reflective surface may be exposed to the outside of the dwelling during the warm seasons to prevent excessive solar radiation from entering a dwelling and reversed during cold seasons to absorb solar radiation and utilize it to aid in keeping the dwelling interior warm.

Abstract: A method and apparatus for welding PVC pipe which includes a means to clamp and apply welding heat so that plastic pipes may be welded while under external pressure adapted to offset internal pressures. The method includes the steps of placing a clamp about a splice to be welded, tightening the clamp and applying heat through the clamp to the plastic in sufficient quantities to cause the plastic to fuse. The steps are carried out by utilizing an apparatus comprised of a clamp which is adapted to encompass the area to be welded and apply a constricting force to that area while heat is transferred through the clamping means to the plastic.
