  • Patent number: 11912946
    Abstract: Various embodiments that pertain to fuel processing are described. A fuel processor can produce an endothermic reaction that cools a substance and produces a processed fuel from a raw fuel. A generator can employ the processed fuel to produce an electricity. The generator can supply the electricity to a load that uses the electricity to function. The load can become hot due to its functioning and can benefit from being cooled. The substance cooled by the fuel processor can cool load and in the process the substance can rise in temperature. This warmer substance can be transferred to the fuel processor to be cooled again and this cycle can continue. Further, the fuel processor can use the warmer substance to achieve the endothermic reaction.

  • Patent number: 8775628
    Abstract: Methods of operating an SIP load balancer, one or more SIP server nodes and/or one or more SIP server instances are provided that efficiently manage a processing load. Configurations for an SIP load balancer, one or more SIP server nodes and/or one or more SIP server instances to enable efficient management of a processing load are also described. In certain ones of these, state data for a set of SIP processes may be sent from a SIP server instance and used by a SIP load balancer to remove inactive SIP processes from a data structure. The management of a processing load comprising a number of SIP processes following the failure of a SIP server node and/or a SIP server instance is also provided.

  • Patent number: 4720652
    Abstract: A sealed beam lamp having an outer envelope defining a gas-tight enclosure filled with an inert nonreactive gas at a pressure in the range of 5 to 50 Torrs, and an illuminating burner capsule mounted within the enclosure. The integrity of the gas-tight enclosure as well as the pressure of the gas is verified by creating a predetermined electrical potential within the enclosure to form a glow discharge in the gas if the gas pressure is within a predetermined range indicating the lamp is serviceable and an arc discharge if the gas pressure is in excess of the range indicating the lamp is defective.

  • Patent number: 4410830
    Abstract: The invention relates to vacuum fluorescent devices having substrates on which anodes coated with fluorescent material are disposed. According to the invention, the substrate comprises a relatively thin layer of insulation on a metal plate so that the acceleration potential in the vacuum fluorescent device may be increased for greater brightness.
