Abstract: A water ring vacuum pump having a body (10) with end members (11,12), an impeller (20) in the body and having a shaft which extends through the end members and being journalled for rotation (24) therein. One end member has an inlet (46) and the other an outlet. A port plate (30) is located in each member and adjacent the ends of the blades (22) of the impeller whereby a manifold (32) is formed between each port plate and its adjacent end chamber, the port plates being moveable relative to their adjacent end members by screws (40) or the like passing through the end member, which screws abut the face of the port plate and can act to vary its location relative to the impeller (20) and locking means (39) passing through the end member and into threads in the port plate whereby the port plate can be moved away from the impeller, which locking means, when the impeller is correctly positioned, acts against the screws or the like which abut the port plate, thus serving to lock the port plate in position.The pump also provides a hollow impeller whereby there can be movement of air direct from the inlet end to the exhaust end through the hollow portion of the impeller.

Title: Water combustion technology-methods,processes,systems and apparatus for the combustion of hydrogen and oxygen
Inventor: HAASE RICHARD A
IPC: F03G6/00
Filed: 2003-04-10
Granted: 2007-02-14
Abstract: This invention presents improved combustion methods, systems, engines and apparatus utilizing H2, O2 and H2O as fuel, thereby providing environmentally friendly combustion products, as well as improved fuel and energy management methods, systems, engines and apparatus. The Water Combustion Technology; WCT, is based upon water (H2O) chemistry, more specifically H2O combustion chemistry and thermodynamics. WCT does not use any hydrocarbon fuel source, rather the WCT uses H2 preferably with O2 and secondarily with air. The WCT significantly improves the thermodynamics of combustion, thereby significantly improving the efficacy of combustion, utilizing the first and second laws of thermodynamics. The WCT preferably controls combustion temperature with H2O and secondarily with air in the combustion chamber. The WCT preferably recycles exhaust gases as fuel converted from water. The WCT minimizes external cooling loops and minimizes exhaust and/or exhaust energy, thereby maximizing available work and internal energy while minimizing enthalpy and entropy losses.

Title: Methods and system for replicating and securing process control data
Inventor: JOHNSON ALEX
IPC: H04L9/00
Filed: 2004-10-18
Granted: 2007-04-04
Abstract: Methods and systems are provided to replicate and secure process control system data. Devices coupled to a process control network produce data that is collected by a host on the network. This data may be provided to users of computers that are not on the process control network, without increasing the network's vulnerability to network attacks. To achieve this security, an isolation system including a firewall and an application workstation are placed between the host and the non-network computers. The host pushes the data through the firewall to the application workstation, which includes the same application program interface found on the host. Thus, non-network computers can not identify that the data provided to them is coming from the application workstation instead of the process control network. The firewall is configured to prevent most or all outside communications with the network. Thus, the network is protected from attacks while providing its data to non-network computers.

Title: Oil-in-water emulsions
Inventor: DAHMS GERD HERBERT
IPC: B01F23/00
Filed: 1993-01-26
Granted: 1995-08-09
Abstract: An oil-in-water emulsion containing 0.5% to 30% metallic oxides having a particle size of less than 0.2 micron, less than 10% total emulsifier, 5% to 30% of an oil phase and at least 60% of an aqueous phase is provided. The invention also makes available a method of preparing such emulsions in which the emulsion is formed by use of a dispersion in water of the metallic oxide particles. By comparison with previously known emulsions of this type relatively small quantities of emulsifiers are used and it is possible to use an emulsion system with a low HLB value (e.g. less than 6). Preferably no hydrophilic emulsifiers are used. The emulsions are suitable for preparing UV-absorbing compositions such as sunscreens, moisturisers and after-sun lotions. The ability to use no, or little, hydrophilic emulsifiers is advantageous since, in, general, these emulsifiers are not biodegradable whereas hydrophobic emulsifiers generally are biodegradable.

Title: Compost heap for household refuse and industrial waste - automatically aerated to obviate turning operation
IPC: C05F/
Filed: 1976-10-19
Granted: 1985-04-10
Abstract: A compost heap is produced by thermal decay of household refuse, industrial waste, drain sludge or other suitable waste. The waste is first broken up to an acceptable particle size, e.g. 10-15 mm and non-usable pieces discarded. The prepd. waste is formed in a heap over a removable former so that the final heap has ground-based, open-ended, tunnels extending deeply into or right through the heap in a longitudinal direction. Above the tunnels, and pref. offset laterally between them, ventilation passages run parallel and coextensively with the tunnels. Chimneys are sunk into the top of the heap almost down to the passages. Automatic aeration ensures that the waste rots down hygienically with no need for any turning.

Abstract: The trunk has a castor consisting of a roller (1) fitted on to a support bracket (2) which pivots on an axis in a roller seating (5). In the seating is a sliding catch (3) which operates with a spring (41) to locate in an upper or a lower notch (21,22) in the roller support bracket (2). The support bracket has a spring (4) so that by releasing the catch plate (3) from the lower notch (22), the castor springs out into its operating position, with the catch plate in the upper notch (21). By releasing the catch the castor can be pushed back into the seating to reduce stowage space for the trunk.
