Abstract: ABSTRACT  This invention disclosure describes a new hard material cutting and drilling tool and cutting system method.  This technique, a high energy abrasive-fluid jet, cuts by accelerating abrasive particles with high velocity eroding fluid jet stream(s).  The concept of using fluid-accelerated abrasive particles for material removal has been demonstrated with both wet sand-blasting techniques and gas powered abrasive jet systems.  In these methods, no deep penetration can be achieved.  Abrasive-fluid jet cutting is an extension to these technologies which produce deep cuts in high strength advanced composites for a wide range of applications. The success of this new technique is achieved by reducing nozzle wear, producing a coherent stream and maximizing the abrasive particle exit velocity.  The advantages of this new technique include versatility in cutting a wide range of material with deep kerfing capability with no fire hazards, low power levels needed, high edge quality, no delamination, no spallin, no thermal distortion, low noise, adaptability to remote operations, contour cutting and availability of the element used.  The potentials for this technique include oil well casing perforation and drilling, use as an augmenting tool, cutting under water, steel platforms for off shore drilling, cutting steel pipe-lines, rock, concrete, glass, metal honeycomb, foams, laminated metal, etc., bore hole mining applications and forming a bottle shape hole by jet drilling.

Abstract: ABSTRACT OF DISCLOSURE      In a receiving circuit a control circuit and a direction finding circuit generate a digitally encoded "descriptor" which characterises pulses of r.f. radiation received in a particular azimuthal direction and having a particular carrier frequency. The "descriptor" may be compared with data stored in a processing circuit representing r.f. pulses emitted by sources which have already been detected or which are known to exist. To reduce the workload on processing circuit a number of emulator circuits generate pulse patterns which simulate pulses produced by known sources of little inherent interest.   If the received pulses match the simulated pulses a gate inhibits control circuit.

Abstract: ABSTRACT      The invention is a process for the manufacture of shaped articles  of  reaction-bonded  silicon  nitride  in which  pre-shaped articles of silicon powder are heated in a first stage under a nitrogen gas pressure of at least 6 MPa at a heating rate of not more than 50°C per hour to a reaction temperature below the melting point  of  silicon,  the  article  is  maintained  at  the  reaction temperature for at least 0.5 hours and subsequently,  in a second stage, heating the article at a heating rate of at least 500°C per hour to a temperature above the melting point of silicon and maintaining the article at that temperature for from 1 to 7 hours.          The process can nitridate both pre-shaped articles consisting of silicon powder and, optionally, up to 15% by weight Si3N4 powder and those containing up to 10% by weight of a sintering aid such as Y2O3.  In the former case, porous shaped articles having a density of from 87 to 91% TD and, in the latter case, dense shaped articles having a density of more than 98% TD, are obtained.  In all cases, in a total nitridation time of less than 15 hours, a conversion of at least 95% of the silicon originally present into silicon nitride is achieved, which, in the finished shaped article, is substantially in the  .beta.-modification.
