Title: Gas discharge devices
IPC: H03K19/02
Filed: 1974-06-21
Abstract: 1479894 Matrix displays OWENS-ILLINOIS Inc 21 June 1974 [22 June 1973] 27576/74 Heading G5C A gas discharge display/memory panel with crossed conductor arrays insulated from the gas comprises cells grouped sufficiently closely together that when a cell in one group is energized a discharge is instituted in the other cells of the group but turning one cell off does not result in all of the other cells turning off; all the cells in a group must be erased together. These operations constitute OR and AND functions. An AND function for a write operation can be obtained by inverting the group as described in Specification 1,479,667. The sustain voltage is shifted to invert the state of the cells from off to on. Erase pulses are applied to all the cells and the sustain voltage again shifted to re-invert the cells when off cells turn to the on state. Using the inversion method erase signals are provided by P-N-P and N-P-N transistor pulses which earth conductors are appropriate times coincident with the sustain pulses. The conductors of each array are arranged in pairs x 1 , a jx 1b  ... y 1a , y 1b  ... the four intersections forming a display element 21. In other panels the elements may be defined by the intersection of one x conductor and two y conductors or three x and three y conductors. It is stated that the cells of a group may be arranged to form letters and numerals. In a display system Fig. 6 (not shown) external connections are taken to the four edges of the panel, groups of conductors are interconnected and supplied via four suitably poled diodes with sustain voltages. The system is inverted by interchanging the potentials to the x and y conductors. Writing is carried out by inverting the cells, energizing the four pulses connected to a selected group to produce coincident erase pulses at a unique location, then reinverting. NOR and NAND operations are referred to.

Title: Improvements in devices for protecting furnaces from flame failure
Inventor: SAWYER WILFRID ALBERT
IPC: F23N5/08
Filed: 1950-11-14
Abstract: 673,350. Photo-electric systems. RHEOSTATIC CO., Ltd. Nov. 14, 1950, No. 27838/50. Class 40 (iii). [Also in Group XI] A photo-cell or conductive probe responsive to the presence of a flame controls a relay to cut off the fuel supply to an oil or gas-burning furnace should the flame fail. In Fig. 1, photocell P when illuminated by the flame develops a steady position grid potential for valve V1 across circuit R1, C1 and causes a large amplitude positive impulse to be produced across cathode load R3 each time the alternating potential on anode 7 becomes positive. These cathode impulses appear on the grid of valve V2 when its anode potential is also positive and the resulting anode current impulses hold relay 12 operated. Condenser C2 prevents the relay chattering. Relay contacts 15 operate apparatus controlling the fuel feed. Potentiometer R4 introduces an alternating potential in opposition with the impulses across R3 and is adjusted to control the circuit-sensitivity condensers C1 and C2 determine the release time of the circuit and are selected to prevent operation from intermittent flicker of the flame. Resistor R5 is included as a precaution against faulty contact in the sliding arm of potentiometer R4. The arrangement is self-protecting in that the relay releases should the emission of either valve fail, or should an open-circuit or short-circuit develop in the photo-cell circuit. To minimize risk of electrical insulation breakdown, the cathode of the photo-cell is chosen as the anchoring point to earth. In Fig. 2 (not shown) the photo-cell is replaced by a probe located within the flame from a metallic burner to detect the electron flame from the base of the flame towards the tip.

Title: A process for the manufacture of carbon black
IPC: C09C1/54
Filed: 1948-09-28
Abstract: <PICT:0654081/III/1> Carbon black is manufactured by mixing a hot gas with a solid, liquid, or gaseous carbon-aceous material, e.g. tar oil, hydrocarbons or oxygen or nitrogen derivatives thereof, animal or vegetable oils, fats and waxes, or natural resins, at a temperature insufficient to crack the carbonaceous material, passing the mixture thus formed into a zone in which it is heated by mixing with a second hot gas so that the average temperature is between 800-1400 DEG  C. and cooling the second mixture in a time of less than five seconds to a temperature at which reaction of the carbon black formed with carbon dioxide and steam does not take place.  In Fig. 1 recycle gas, a mixture of hydrogen and nitrogen, is fed from gas holder 26 by conduit 30 through heated regenerator 1 containing checker bricks 3 to reaction chamber 4 wherein air is admitted at 11 to increase gas temperature to, say, 1700 DEG  C. Hydrocarbon oil from nozzle 55, Fig. 3, is carried by hot gas from burner 48 through refractory lined tube 51 into the hot gases in reaction chamber 4 at 7 and the contact time is restricted by cooling to, say, 1000 DEG  C. by gas entering at 10.  The resulting gas mixture is passed through carbon black precipitator 23 and thence to gas holder 26 whence part is recycled through conduit 30, part is used as cooling gas through conduit 10, part, supplemented with oil at 22, reheats regenerator 2 by combustion with air admitted at 18, and part may be used as a fuel for other purposes; the air passes through reaction chamber 14 to remove any carbon deposited in the previous cracking.  Regenerators 1, 2 are then reversed in action and chamber 14 used for cracking. In starting up, the apparatus may be heated by hydrogen or steam supplied at 5.  Alternative apparatus is also described where a regenerator is not employed, all the necessary heat being produced by burning recycle gas.
