Abstract: A method of generating steam for use in an industrial process is disclosed. The industrial process may for example be power generation or desalination. The method comprises: (a) pressurising a working fluid liquid comprising water to a first pressure; (b) heating the working fluid liquid to a temperature substantially equal to the saturation temperature of the working fluid liquid at the first pressure; and (c) flash evaporating the working fluid liquid to generate steam. The pressurised working fluid liquid is heated in step (b) by direct heating in a solar radiation absorption device. Also disclosed is an apparatus for generating steam for use in an industrial process.

Abstract: There is disclosed a method of generating superheated steam for use in power generation. The method comprises: (a) preheating feed water to a temperature below its boiling point; (b) boiling the preheated feed water to produce steam; and (c) superheating the steam. The feed water is boiled by heat exchange with a heat transfer fluid which has been heated by heat collected in a first solar radiation absorption device. In addition, one or other or both of the preheating and superheating is carried out by direct heating in a further solar radiation absorption device or devices. The invention also relates to an apparatus for generating superheated steam for use in power generation.

Abstract: A yoga block system which includes a first block and a second block which can either be rectangularly shaped or triangularly shaped. These blocks are capable of joining with one another, releaseably, along either a common face when the blocks are rectangular or along the hypotenuses when the blocks are triangularly shaped. At least one of these blocks is preferably hollow enabling a user to gain access to its interior. Notwithstanding the elements used to join them, each block presents to a user faces which remain substantially planar.

Abstract: ∝-2 adrenergic receptor agonists are used as medication for recovering addicts, to prevent or reduce the stress-induced reinstatement of seeking the addictive materials ethanol or nicotine. Suitable alpha-2 adrenergic receptor agonists include guanabenz, clonidine, and especially lofexidine.

Abstract: A communications system autonomously establishes, monitors, and maintains a secure and persistent internet “tunnel” communication path between one or more interconnected computers located at a “central” site and at least one host computer of a plurality of host computers at sites remote from the first site. The system includes a tunnel terminator server at the central site, following a secure tunneling protocol. The tunnel terminator server includes a public port interface coupled to the internet. The tunnel terminator initially establishes a clear communications link clients calling from the internet, and initially identifies and authenticates each of the clients as being “authorized.” For each client so identified and authenticated, the tunnel terminator establishes an encrypted communications link, and provides a new private IP address to each individual client by the link.

Abstract: A spacecraft includes bipropellant and monopropellant engines or thrusters. The oxidizer-fuel mixture ratio of the bipropellant engine is not known exactly. The spacecraft is loaded with only sufficient oxidizer to achieve the velocity for transfer from an intermediate orbit to geosynchronous orbit if the mixture ratio is nominal. Therefore, more fuel can be loaded. If the bipropellant engine burn is nominal, there is no excess oxidizer when on-orbit and more fuel is available for stationkeeping. If the burn is oxidizer-rich, there is a velocity shortfall, which is made up by firing monopropellant engines. If the burn is oxidizer-lean, the geosynchronous orbit is achieved with a load of excess oxidizer, which must be moved during each stationkeeping maneuver. A net gain of stationkeeping time results in any of the three mixture ratio cases by comparison with loading of sufficient oxidizer for a full bipropellant burn under worst-case mixture conditions.

Abstract: A spacecraft includes a pair of pressurized propellant tanks. The pressure may be provided from a common pressurant tank. Each propellant tank has a propellant output port. A manifold includes a first branch coupled between a common juncture and the output port of the first tank, and a second branch between the juncture and the output port of the second tank. At least the second tank is associated with a heater. A controllable valve, such as a normally open pyrovalve, is coupled in the second branch. In order to fully utilize the propellant in the tanks, the second tank is differentially heated relative to the first when the tanks are nearly empty, to create a tendency toward a pressure difference, which drives propellant from the second tank to the first. When all or most of the propellant is transferred, the valve is operated to close off the second branch of the manifold, to isolate the now-empty tank.

Abstract: The unknown amount or mass of liquid contained in a storage tank is measured by calibrating the tank in an empty and partially full condition. The calibration includes measuring the mass of the empty tank, and is accomplished by applying a measured amount of heater power or energy to the tank and its contents, and measuring the temperature response to determine the product of total mass multiplied by specific heat. The specific heat depends upon the mass or amount of liquid in the tank, but a linear relationship is established between total mass and the product of total mass times specific heat. The unknown mass of liquid is then determined by applying a known amount of heater power or energy to the tank and its contents, and measuring the temperature rise or rate of rise in response thereto.

Abstract: A fuel or fluid level measurement arrangement for a spacecraft includes one or more electromagnetic transmission lines extending into the reservoir. The presence of fuel adjacent the transmission line changes the dielectric constant or loss characteristics of the transmission line(s) in a measurable manner. In one embodiment, strip transmission lines extend parallel to the fluid surface at various degrees of ullage, and the fuel level can be established to within the spacing between the transmission lines.

Abstract: An edge connector (1) comprises a housing (2) having an aperture (3) in which an edge (6) of a circuit board (7) is received. One or more connector pins (12) (13) extending from the housing each have a sharp-edged contact region (19), plated with a ductile metallic material such as tin or lead, and capable of penetrating and deforming a similarly plated contact pad (20) to establish a low resistance electrical connection therebetween. The housing (2) and the circuit board (7) are pivotable with respect to one another between a first position in which there is clearance between the connector pins (12) (13) and the contact pads (20) present on the circuit board, and a second position in which they are in electrical contact one with the other. Securing means such as resilient clips (25) (26) (30) (34) hold the circuit board with respect to the housing (2) in the second position.

Abstract: A distance measuring apparatus comprises a first modulating cavity for modulating a first electromagnetic carrier radiation, the modulated first electromagnetic carrier radiation being transmitted over a path the length of which is to be measured and received by a second modulating cavity which determines the modulation phase thereof. The second modulating cavity also modulates a second electromagnetic carrier radiation in accordance with the modulation phase of the received modulated first electromagnetic carrier radiation and transmits the modulated second electromagnetic carrier radiation back over the path the length of which is to be measured. The first modulating cavity detects the modulation phase of the received modulated second electromagnetic carrier radiation and produces therefrom an indication of the length of the path.
