Abstract: A coffee roaster which roasts coffee beans in an 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 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 includes an upper transparent section through which the roasting charge of beans may be viewed and thereby allow manual control of the process in response to visual observation.

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: 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 paging encoder including a microcomputer having a look-up table containing code formats for the more popular paging systems and an energy conservation means whereby the microcomputer is maintained in an off state except when called upon to perform an encoding function by a keyboard input means. This is accomplished by a microcomputer programmed to contain a lookup table including tone and space data for a plurality of paging formats and routines for converting input data, such as a telephone number, to a tone and space code for a selected one of said paging formats as programmed by a selection means which alters the function of the microcomputer to cause it to provide the desired output tone and space codes in accordance with the selected paging format.

Abstract: An automatic radio telephone encoder/decoder including a microcomputer programmed to decode incoming dial codes and generate outgoing radio telephone functions and dial codes in response to received signals or keypad activation is presented in combination with control circuitry activated by the microcomputer which is maintained in an off condition except when called upon to perform encoding or decoding functions by a keyboard input means or signals received by the radio telephone.

Abstract: A check or credit card monitor consisting of a plurality of normally closed switches adapted to be held open by insertion of credit cards or similar items between the switch contacts. The contacts are connected in parallel to a timing means adapted to energize a sensory alarm such as an audio signal, vibrator or light a predetermined time after closure of any one of said plurality of switches.
