Abstract: A muzzle velocity chronograph method and apparatus is described for measuring the velocity of a projectile (11) from a gun (13). In this method and apparatus a conventional radar Doppler signal from a radar device (15) is sampled and digitized by an analog-to-digital converter (23) and arranged in a succession of groups, each group representing a separate time period. A fast-Fourier transform is them computed for each group of samples by a signal processor (27) and peaks frequency measurements in the transformed data are tracked from one time period to the next. These peaks indicate the velocities of the projectile of interest and any other nearby moving objects. Finally, a least mean square error curve fit and standard regression algorithm are used to deduce the projectile's initial, muzzle velocity and the results displayed on a display (31). The method and apparatus provides accurate muzzle velocity determinaltions even in circumstances where the Doppler signal contains substantial interference caused, for example, by random noise and the presence of moving fragments in the direction of the projectile.

Abstract: An interconnection network management architecture for use with a large shared memory multiprocessor com­puting system including a plurality of processors and a plurality of separately addressable main memory modules. Two parallel, interconnection networks are provided each capable of interconnecting any processor to any memory module, and each having different latency characteristics. A Hot-Spot detection means is associated with each main memory module for detecting when a par­ticular address in that module has become a Hot Spot and includes a first memory for storing all detected Hot Spots. A diverter element is associated with each pro­cessor for selectively routing memory requests over either said first or second memory network con tingent on its status as a Hot Spot. A second memory is included in each diverter element for storing all Hot Spots detected by the detector elements. 
     A control mechanism determines if any current main memory address is a listed Hot Spot within said second memory and, if so, causes the main memory reference to be transmitted to the memory system over a selected interconnection network. 
     Another component of this mechanism determines if a particular address has been accessed a sufficient number of times within a given timeframe to be deemed a Hot Spot and removes Hot Spots from both the first and second memories when necessary.

Abstract: The invention relates to a process for the production of a baseplate with recesses etched into its surface for an ink jet printing head in ink jet mechanisms, the jet outlets being in at least two rows and the baseplate being made of a photosensitive glass material. According to the invention, the baseplate (1) is exposed to light to which the glass material is photosensitive through two vapour-deposited chromium quartz glass masks which are of mirror-symmetrical design and which have the same printing head layout. In the next process step, the glass material is thermally treated by heating to a temperature at which the amorphous glass structure is converted into a ceramic crystal structure in the exposed regions. The baseplate (1) is then immersed in an etching solution to remove the crystalline phase of the glass material. For an ink jet printing head with two rows of jet outlets (7) and only one baseplate (1), the method described results in high print quality and is less expensive than constructing and aligning two individual heads.

Abstract: A surface discontinuity is formed along an anode nozzle bore sufficiently upstream of a nozzle exit orifice (34a) and of a sufficient size to cause an arc between an electrically conductive end wall of a plasma-arc torch anode nozzle passage (34) and a coaxial cathode (32) coaxially mounted by an opposite end wall of the torch cylindrical casing having a gas under pressure and at an established vortex flow to pass through the nozzle passage (34). A boundary layer of the vortex flow of gas along the anode bore wall provides a path for the arc to pass directly to the anode nozzle passage (34) at or just downstream of the disturbance zone provided by the nozzle passage (34) wall surface discontinuity. A counterbore (57) may extend along a portion of the nozzle axis from the nozzle exit (34a) axially inwardly to form a radial shoulder (58) with the main bore of the anode nozzle (31) and define the discontinuity. Alternatively, a shallow annular groove (60) may be machined into the anode nozzle bore, or an annular ring (76) may project radially inwardly of the nozzle passage bore to constitute such alternative surface discontinuity. Material may be sprayed into a high velocity hot gas stream downstream of the arc column and its downstream ionized region to eliminate excessive heating of the particles sprayed by the torch. A reduced diameter nozzle bore section may be provided between the terminus of the arc column and/or its associated downstream ionized region and the   point of the introduction of the material to be sprayed, with the reduced diameter nozzle bore forming a nozzle throat of an expansion nozzle producing a supersonic jet stream at the nozzle exit.
