Abstract: A portable heating system used to heat a person while in cold environments. A heating unit containing a fuel combustion chamber and a heat exchanger oxidizes a fuel to produce heat. The heat from the oxidation process is transferred to the fluid using the heat exchanger. The fluid either boils or simply becomes less dense than cooler fluid in the heat exchanger and thus more buoyant. Convection moves the heated fluid upwards in to a thin bladder encapsulating the fluid and held against a person. The elevated kinetic energy in the bladder creates an entropy differential to the person. This differential allows the kinetic energy in the bladder to flow to the person thus warming them. The fluid now having less energy, now denser, flows back down the bladder to the heating unit by gravity.

Abstract: A therapeutic cooling system used to remove trapped heat from between a person and an object pressed against the person. Such objects would include: beds, chairs and protective clothing such as body armor. A thin bladder encapsulating a liquid placed between the person and heat trapping object absorbs heat produced by the person. Increased heat transferred to the liquid causes it to expand, become less dense and thus more buoyant than the cooler liquid in the bladder. Convection moves heated liquid upwards towards a thermoelectrically driven cooling unit. When the warmed liquid reaches the cooling unit thermoelectric devices pull heat from the liquid and push it in to a heat sink where is it can expelled from the system. The cooled liquid, now denser, flows back down the bladder by gravity.

Abstract: The invention relates to the polynucleotide sequence of a nontypeable stain of Haemophilus influenzae (NTHi) and polypeptides encoded by the polynucleotides and uses thereof. The invention also relates to NTHi genes which are upregulated during or in response to NTHi infection of the middle ear and/or the nasopharynx.

Abstract: A method and system for providing a network which routes telephone calls to the dial-up access line of on-line data services, such as an Internet Service Provider. The calls are routed over, over data trunks to a circuit-switch that consolidates access to on-line data services. The data trunks are separate from trunks carrying normal voice telephone calls. At the originating office where the telephone call originates, the call is recognized as a call to a telephone number associated with the dial-up access telephone number of an on-line data service. A database selects a route over a data trunk to the terminating office having a circuit-switch that consolidates access to the on-line data services. The consolidation of access to on-line data services over segregated data trunks to a single circuit-switch reduces congestion in the network by relieving the network from handling a large volume of long duration telephone calls.

Abstract: A method is provided for synthesizing acylamides, useful as protectant for cultivated plants. A benzoxazine, such as 3,4-dihydro-3-methyl-2H-1,4-benzoxazine, is made in a stepwise manner by initially forming an o-nitrophenoxyketone by reacting a haloketone and a nitrophenol. The o-nitrophenoxyketone is hydrogenated to form the corresponding benzoxazine, which is thereafter acylated with an acylhalide to produce the acylamide, such as 4-dichloroacetyl-3,4-dihydro-3-methyl-2H-1,4-benzoxazine.

Abstract: The invention described herein relates to a Haemophilus influenzae (H. influenzae) regulon encoding type IV pili. In particular, the invention relates to type IV pili from nontypeable H. influenzae (NTHi) and from H. influenzae strains a, b, c, e and f. The invention provides isolated H. influenzae pilus polynucleotides and polypeptides encoded by the polynucleotides as well as polynucleotides and polypeptides encoded by the polynucleotides involved in the assembly/disassembly of the structure. The invention also relates to uses of these polynucleotides and/or polypeptides including methods for eliciting an immune response to H. influenzae and methods of treating and preventing H. influenzae related pathological conditions.

Abstract: A timer whose purpose is to apply or remove power to or from an attached load during a monostable timing interval. A selection switch determines whether the attached appliance is on or off during the timing interval. The period of the timing interval is determined by the adjustment of a potentiometer or other control element and the timing interval is initiated by the closure of a momentary contact switch. Standard electrical interfaces are provided to allow the device to be interfaced to a standard receptacle and to provide a similar receptacle to the attached appliance.

Abstract: A viscous fluid timer is constructed with a cylindrical cavity formed by a housing that supports an axially aligned rotor unit having a rotor on a shaft within a first chamber filled with a viscous fluid. The first chamber communicates with a second chamber having a shaft seal through which the rotor shaft projects, the rotor shaft having a torsional connection to a spring means for rotating the rotor unit within the chamber, the first chamber being filled with a highly viscous fluid which impedes the rotation of the rotor.
