Abstract: ABSTRACT    A monochromatic and polychromatic display system (10) which is operative by the generation of ultraviolet energy impinging on fluorescent material compositions (54) in order to create electromagnetic wave generation within the visible bandwidth of the electromagnetic spectrum through fluorescent excitation of fluorescent material (54).  The operative ultraviolet energy produced results from the ionization of metallic atoms from a metallic coating (28) applied to cathode opening sidewalls  (26) of a cathode mechanism (12).  The display system (10) in-cludes a matrix of cathode openings (22) formed in a cathode plate member (14).  The cathode openings (22) define the cathode opening sidewalls (26) which have a metallic coating (28) applied thereto.  The sidewall metallic coatings (28) and additionally, the metallic coating annular portion (30) of each hollow cathode cavity are coupled to a next succeeding cathode element in a linear column direction (32).  A matrix of anode elements (46) are mounted below the cathode plate member (14) and are axially aligned with the cathode openings (22).  The display sys-tem (10) is formed into a monolithic structure which in-cludes an internal chamber (??) within which an inert or combination of inert gases is introduced.  Fluorescent material compositions (54) are positionally located in aligned relation above cathode openings (22).  Electrical energization of the cathode elements and the anode elements (46) results in ionization of metal atoms emitted from the metallic coating (28). The ionization process pro-vides for ultraviolet radiation which is directed to the fluorescent material composition (54).  The display system (10) allows for a wide dynamic range of light intensity with an optimization of the reproducibility of physical characteristics.  More importantly, the display system (10) provides a visual display substantially devoid of any flicker within the visible bandwidth of the electromagnetic spectrum.

Abstract: RECLINING CHAIR WITH IMPROVED ACTUATION                     ABSTRACT OF DISCLOSURE      A three-way, wall-avoiding, reclining chair having an improved actuation system which minimizes the effort and atten-tion required of the chair occupant to actuate the chair to reclining position from the normal generally upright position of the chair.  The improved actuation system is achieved by a novel seat linkage mechanism mounting the seat and backrest to a fixed base such that when the occupant sits in the chair when the chair is in the normal generally upright position with the footrest closed, the seat linkage mechanism is urged by the occupant's weight to extend the footrest while moving the seat and backrest forwardly relative to the base into the TV posi-tion.  However, a releasable lock mechanism is provided to restrain the seat linkage mechanism from moving to the TV posi-tion as aforementioned.  A manually operable release is asso-ciated with the lock mechanism to allow the chair occupant to release the lock mechanism thereby allowing the chair to move into the aforementioned TV position responsive to the weight of the chair occupant.  Once in the TV position, the chair may be moved to a further reclining position by the chair occupant simply applying back pressure to the backrest while opening his body causing the backrest to move relative to the seat, and the seat and backrest to move relative to the base into a more pro-nounced reclining position.  To return to the TV position, the occupant merely has to remove pressure from the backrest or lean forwardly in the chair.  To move from the TV position back to the normal, generally upright position, the occupant merely closes the footrest by applying pressure with his feet or legs on the footrest to retract the same to closed position which also actuates the seat linkage mechanism to restore the seat and backrest to the normal position.

Abstract: Abstract:            A Process of Cleaning Flue Gases From Heating Plants, and a Cleaning Plant for Carrying Out the Process.            By a process of cleaning flue gases, both solid parti-cles and nitrogen oxides and sulphur dioxide are removed from the flue gas prior to the discharging into the atmospheric air. In order to ensure that almost all the content of sulphur dioxide and nitrogen oxides is re-moved from the flue gas, said flue gas is initially carried through a rain of aqueous liquid and subsequent-ly through a heat exchanger, in which its temperature is lowered to about 20-30°C, and then through a film of alkaline liquid, and finally through a second rain of aqueous liquid to pass a sulphuric acid neutralizing liquid in a container before the discharging into the atmospheric air. As a result a simultaneous possibility of utilizing the heat of the flue gas is ensured by means of the heat exchanger. A cleaning plant for car-rying out the process comprises an apparatus (2), through which the flue gas cleaned of solid particles is carried. When seen in the flow direction, this appa-ratus comprises a first flue scrubber (8), in which the flue gas is subjected to a rain of liquid, a two-step heat exchanger (9, 10) permitting a reduction of the temperature of the flue gas to 20-30°C. After the two-step heat exchanger (9, 10), the apparatus (2) com-prises a rotating, conical disc (11) providing a film of milk of lime, through which the flue gas is forced to pass during the continuous flow through the appara-tus. After this film of milk of lime, the flue gas passes a rain of liquid emitted from a second flue scrub-ber (14), and Upon said scrubber the flue gas is forced to pass a limy liquid in a container (15).

Abstract: PROM ERASE DETECTOR                      Abstract A programmable transistor is provided adjacent to a programmable read only memory.  A latch is used in conjunction with the programmable transistor and data is written into the latch.  If the programmable transistor is programmed the output of the latch will be modified, however, if the programmable transistor is not programmed the output of the latch will not be modified when it is read.  The programming pads used to program the programmable transistor are severed so they are no longer functional once the programmable transistor has been programmed.  Therefore if someone erases the programmable read only memory the programmable transistor is also erased and cannot be reprogrammed.

Abstract: ABSTRACT OF THE DISCLOSURE Halftone images are formed from dots selected from a dot character font memory storing information representing halftone dots of different sizes and shapes corresponding to different gray scale tone values or image densities.  An original image is first scanned to sample its tone values at minute intervals exceeding the desired dot resolution of the reproduction. These sample values are digitized by an A/D converter which converts them to multibit binary numbers.  Adjacent samples are compared to determine the average image density in a particular area. as well as the rapidity of rate of change of image density within that area.  If the rate of change of image density in a given area is below a selected threshold value, the area is designated as low detail and the multibit binary number representing the result of the average density calculation over the area is used to select a dot character from the font memory for reproducing that area of the image.          If, however, the rate of change of image density exceeds the selected threshold value, indicating an area of relatively high detail, the area samples are used to select special dot shapes and positions for use in reproducing that sampled area, This technique achieves a higher resolution halftone image for a given amount of stored data than prior techniques, as well as achieving a higher "apparent" resolution to the observer.

Abstract: ABSTRACT OF THE DISCLOSURE      There is disclosed new and improved photo-voltaic devices which provide increased short cir-cuit currents and efficiencies over that previ-ously obtainable from prior devices.  The dis-closed devices include incident radiation direct-ing means for directing at least a portion of the incident light through the active region or re-gions thereof at angles sufficient to substan-tially confine the directed radiation in the devices.  This allows substantially total utiliza-tion of photogenerated electron-hole pairs.  Fur-ther, because the light is directed through the active region or regions at such angles, the active regions can be made thinner to also in-crease collection efficiencies.    The incident radiation directors can be ran-dom surface or bulk reflectors to provide random scattering of the light, or periodic surface or bulk reflector to provide selective scattering of the light.  While the present invention is applicable to photovoltaic devices formed from any type of semi-conductor material, as for example, crystalline, polycrystalline, or amorphous semiconductor alloys or any combination thereof, disclosure herein is primarily directed to photovoltaic devices formed from amorphous silicon alloys preferably incor-porating fluorine as a density of states reducing element.  The disclosure is also directed to, without limitation, photovoltaic devices of the p-i-n configuration, both as single cells and multiple cells arranged in tandem.
