Abstract: A lamp assembly comprising one or more lamp clusters. Each lamp cluster comprises one or more electrodeless UV lamps which are excited by microwaves emitted from a microwave generator. The microwave generator and power supply are enclosed within a housing that is integral with the lamp clusters. The lamp clusters are wholly surrounded by a waveguide. The waveguide, comprising a flange and a distal end cap connected by a mesh, forms an enclosure. The waveguide is essentially UV transparent to allow UV light to pass through but effectively opaque to microwaves in order to substantially contain the microwaves within the waveguide enclosure.

Abstract: An exhaust gas reactor is disclosed which utilizes microwave energy to create a plasma whereby chemical reactions are promoted. Such reactions serve to reduce pollutant emission. The processor has a microwave-resonant cavity (6) formed either in an exhaust passage of a combustion chamber or in the combustion chamber itself, the cavity receiving in either case exhaust gases released by combustion in the chamber. Subjection of the exhaust gases to microwaves causes them to form a plasma in which chemical reactions take place.

Abstract: A fuze may include a detonator, a firing capacitor and a control circuit. The firing capacitor may be charged to a nominal operational voltage, wherein when the firing capacitor is discharged across the detonator, an external explosive charge may be detonated. The firing capacitor may also be charged to a sterilization voltage, wherein when the firing capacitor is discharged across the detonator, the detonator may be destroyed without causing detonation of an external explosive charge. When the detonator is destroyed, the sterilized fuze is unable to trigger detonation of an external explosive charge.

Abstract: Process steps are provided for electronically sending promotional and advertising materials based upon consumer preferences by providing a unique identifier to a consumer's electronic mail address and sending electronic mail to the consumer, wherein the electronic mail includes a plurality of embedded Internet web sites. Thereafter, the consumer accesses the plurality of embedded Internet web sites in response to the sent electronic mail, and consumer movement within the plurality of accessed embedded Internet web sites is tracked. Promotional material can then be sent to the consumer based upon the tracked consumer movement within the embedded Internet web sites. Process steps are also provided to track consumer movement without the consumer's electronic mail address, if the consumer makes a purchase with a credit card while at a seller's web site. The IP address is linked to the credit card to track consumer movement within the web site.

Abstract: A computer virus scanning system is described in which during the scanning operation a measurement value indicative of the amount of data processing performed is calculated and this measurement value used to trigger breaks in the virus scanning operation. The triggered breaks can be used to perform a determination as to whether or not the virus scanning operations should be early terminated. One possibility is to measure the total size of the data processed during the virus scanning operation and calculate a ratio of this compared to the size of the computer file being virus scanned. If this calculated ratio exceeds a predetermined threshold, then virus scanning may be terminated. Another possibility is to associate a complexity value with each of a plurality of tests applied in the virus scanning operation. A total for these complexity values may be used to trigger the breaks and also to trigger early termination upon exceeding of respective threshold levels.

Abstract: Apparatus suitable for vitrifying nuclear waste comprises a tunable microwave cavity connected by a first wave guide to a source of microwave energy; cooling coils for cooling the exterior of the cavity; a hopper for loading particulate fusible material to the interior of the cavity; within the cavity a crucible made of melted and re-solidified fusible particulate material; an exit-chamber connected by a second waveguide to a second microwave source; and a pipe for supplying argon gas to the exit chamber so that a plasma torch can be generated. The separating of the crucible form the cavity walls by unmelted material gives significant advantages in case of cleaning and reduced energy consumption.

Abstract: An explosion resistant structure comprises arcuate interlocking cold roll formed profiled steel panels (59) over which an outer (51) of steel reinforced concrete is formed. The outer concrete skin (51) is formed integrally with a steel reinforced concrete base (60) in turn formed integrally with a steel reinforced concrete floor. Planar front and rear walls (54, 63) are formed by planar cold roll formed profiled interlocking steel panels of a similar configuration to the arcuate roof panels and a steel reinforced concrete skin is also formed over the planar steel panels. The profiled steel panels (70) are of a substantially U-shaped cross section, the upper portions (72) of the side walls (76) being interlocked and the entire side wall portions and interlocked portions are encapsulated in the steel reinforced concrete layer to form a substantially continuous steel skin over the inner surface of the structure.

Abstract: A gas plasma generating system includes a resonant cavity for connection to a source of very high frequency power. A plasma cavity is defined by a wall of an electrically nonconductive material positioned within the resonant cavity for containing an ionizable gas such that in use a plasma is formed in the plasma cavity, the cavity having an exit opening to enable plasma to exit from the system. The plasma cavity comprises a tubular member extending through opposed walls of the resonant cavity, the tubular member receiving at one end a plasma gas, in use, and plasma exiting from the other end, and a movable tuning member whose position can be adjusted to achieve the desired tuning condition, the tubular member defining the plasma cavity extending through the tuning member.

Abstract: Data communications connections between interactive terminals and host computers generally exhibit long holding times, while the data density of the transmissions is sparse. The circuit switch of a switching system is an inefficient and expensive medium for this type of communication. Thus, the subject switching system uses a packet switch connected in parallel with the circuit switch to handle bursty data traffic from interactive terminals. A routing bit is set in the data stream from each port circuit to indicate the nature of the transmission and this transmission is then routed to the packet switch if it is a bursty data transmissions while voice messages are routed to the circuit switch.
