  • Publication number: 20160006066
    Abstract: An improved system of hardware and controls, known as a Hyper Hub, that absorbs electric power from any source, including hydropower, wind, solar, and other renewable energy resources, chemically stores the power in hydrogen-dense anhydrous ammonia, then reshapes the stored energy to the power grid with zero emissions by using anhydrous ammonia to fuel diesel-type, spark-ignited internal combustion, combustion turbine, fuel cell or other electric power generators, and for other purposes.

  • Patent number: 6192254
    Abstract: An improvement in the transparency of personal telecommunications over the prior art is achieved by automatically placing a return call from a personal communications unit of a called individual in response to a call from a caller and alerting the called individual to the existence of the call placed to his personal number only upon an indication that the call from the calling telephone remains in progress. In one embodiment of the invention, the called individual associates his personal communications unit with a telephone channel, before his reception of any calls. Should a caller make a call to the called individual's personal calling number, the telephone network causes the transmission of an actuation signal. In response to the actuation signal, the personal communications unit places a call to a predetermined number over a switched telephone network using the aforementioned associated telephone channel.

  • Patent number: 5607491
    Abstract: An air filtration media comprises a single layer of randomly oriented and randomly intermingled synthetic, polymeric resin microfibers, staple fibers and bonding fibers. The microfibers, taken as a whole, have an average fiber diameter no greater than 5 microns and comprise between 50% and 90% by weight of the filtration media; the staple fibers, taken as a whole, have an average fiber diameter between 10 and 30 microns and typically, comprise between 5% and 45% by weight of the filtration media; and the bonding fibers, taken as a whole, have an average fiber diameter between 0.9 and 15 denier and comprise between 5% and 25% by weight of the filtration media. The bonding fibers have thermoplastic surfaces with a lower temperature softening point than the microfibers and the staple fibers and bond the fibers together to form the air filtration media.

  • Patent number: 5473677
    Abstract: The present invention provides real time call control within a telecommunications network, using a call selection processor separate from the switches carrying the call, which responds to incoming calls and uses information carried in the associated signaling messages to determine what application processor, if any, should be involved on the call. One embodiment of the present invention includes a call selection processor called a signaling director", or "SD" for short, for recognizing certain signaling messages, typically SS7 initial address messages (IAM's), as the messages flow through the signaling network. Alternatively, particular signaling messages may be recognized in a signaling message processing element within the signaling network, such as the signal transfer point (STP) associated with the switch that receives the telephone calls, and a copy of those particular messages forwarded to the SD.

  • Patent number: 5437922
    Abstract: A fibrous, non-woven thermal insulation comprises synthetic polymeric resin microfibers, staple fibers and bonding fibers which are randomly oriented and randomly intermingled in a single layer. The microfibers comprise between 25% and 95% by weight virgin synthetic polymeric resin and between 5% and 75% by weight recycled polyethylene teraphthalate. The microfibers have an average diameter between 1 to 8 microns and comprise between 35% and 80% by weight of the insulation; the staple fibers have and average diameter between 10 and 30 microns and comprise between 15% and 60% by weight of the insulation; and the bonding fibers have an average diameter between 14 and 30 microns and comprise between 5% and 25% by weight of the insulation. The bonding fibers have thermoplastic surfaces with a lower temperature softening point than the microfibers and staple fibers and bond the fibers together to form the insulation material.

  • Patent number: 5361466
    Abstract: A synthetic microfiber blanket having a uniform thickness is formed from a nonuniform blanket having thin or feathered lateral edges. The nonuniform blanket is cut transversely into a plurality of discrete pieces of blanket of uniform length. The plurality of discrete pieces of blanket are arranged with the thin lateral edges in overlapping relationship to form a blanket of a desired width and thickness. The overlapped, discrete pieces of blanket are then joined into an integral blanket of uniform width and thickness by entangling together fibers of adjacent pieces of blanket. A scrim backing can be incorporated into the blanket for added strength and dimensional stability.

  • Patent number: 4168328
    Abstract: The invention relates to the long term stabilization of proteinaceous food products both for human and for animal consumption, having a moisture content exceeding 50% and preserved against microbiological spoilage by a pH value of 4.5 or below. The long term stabilization of such products is enhanced by the presence of viable homofermentative acid producing organisms, notably lactic bacteria, together with available fermentable carbohydrate. In the preferred process the pH value of a proteinaceous product is reduced to a value in the range 5.0 to 4.0 and fermentation of the bacteria is then brought about, whereby the pH value of the product attains a final value not exceeding 4.5, if necessary with a lowering of pH value by the action of the bacteria. In preferred embodiments of the process a food grade acid is added to reduce the pH of the product to the range 4.5 to 4.0 and the final pH value of the product lies in the range 4.3 to 3.8.
