Abstract: ABSTRACT OF THE DISCLOSURE   An igniter for gas discharge pipes such as flare lines produces a remotely controlled flame.  The igniter has a tubular housing that is mounted to the gas discharge pipe.  A fuel line extends through the housing and terminates in a nozzle.  A swirling device creates a swirling motion in the nozzle to prevent extinguishment due to high winds.  An electrical system creates an electrical spark in the nozzle to ignite the fuel.  An auxiliary line provides fuel unmixed with air to the nozzle to enrichen the mixture and provide coloration to the flame.  The nozzle extends laterally from the hous-ing.  The mounting means allows the nozzle to discharge the flame across the face of the discharge pipe.  A heat shield protects the upstream end of the housing from heat due to the discharge pipe.

Abstract: A system for predicting ventricular tachycardia from electrocardiograph input waveforms.  A high pass filter provides an output responsive to the input waveforms. A time derivative of the filter output is generated to produce waveforms which can be compared to a standard. In one embodiment, the input waveforms are digitized prior to processing by the filter means.  In another embodiment, digitized input waveforms are signal averaged prior to processing by the filter.  The filter can be a finite impulse response filter of an infinite impulse response filter.  In an alternate embodiment, a ventricular tachycardia prediction system for use with ECG waveforms having cyclical characteristics is disclosed. The ECG waveforms are periodically sampled during each of a plurality ECG cycles.  A filter unidirectionally filters the signals for each ECG cycle so as to provide a filter output systematically related to the high frequency content of the input.  A reference signal is provided for ventricular tachycardia prediction.  The filter output is compared to the reference signal, and a propensity for episodes of ventricular tachycardia is indicated responsive to the comparison.

Abstract: METHOD FOR MANUFACTURING  A SEMICONDUCTOR DEVICE            Abstract A method for manufacturing an IGFET device which provides IGFETs having extremely shallow source and drain regions and reduced gate to source and drain overlap capacitances is disclosed.  For silicon MOS devices, the method also provides for the formation of metal silicide layers on polysilicon gate electrodes and interconnection paths and the source and drain regions in the same fabrication step.  Source and drain regions are formed by oxidation of an arsenic doped polysilicon source layer formed to be in contact with areas in the silicon surface in which such regions are to be formed.  The thickness of the source layer and the conditions of oxidation are such that the rate of oxidation of the source layer exceeds the rate at which arsenic diffuses in the silicon at the oxidation temperature and that during the oxidation time, the arsenic in the source layer diffuses into the silicon to form extremely shallow source and drain regions.

Abstract: ABSTRACT       A capacitive pressure transducer utilizing a plate of electrically conductive semi-conductor material sandwiched between a pair of plates of inorganic electrically insulating material and electrostatically bonded thereto. A pair of concentric circular recesses are etched in the plates in such a way as to form cavities on opposing sides of the conductive plate and to define a diaphragm area on that plate.  Apertures are drilled through the insulating plates to expose the cavities to the pressures to be measured.  The surfaces of the insulating plates in the cavities have deposited on them electrically conductive surfaces which form capacitors with the diaphragm area on the conductive plate.  A stress relief area is provided on the high pressure side surrounding the diaphragm area. In that stress relief area, the conductive plate is unrestrained by the adjacent insulating plate.  Provision of this stress relief makes it possible to extend the pressure range of the transducer beyond the range which would normally be useful for the dimensions of the particular transducer.

Abstract: Abstract of the Disclosure This invention relates to an apparatus for preparing samples.  These samples will be used for making disks and solutions for subsequent analysis by chemical or physical means.  The machine contains an assembly of several gas bur-ners with a crucible above each of them for heating and melt-ing the sample-flux mixture.  Efficient mixing in the melt is obtained by providing a crucible with a new shape in com-bination with a periodic tilting or rotation of the crucible.          Solutions are prepared by pouring the hot molten glass mixture into beakers containing an acid and by agitating the acid and the glass particles.  Glass disks are prepared by placing moulds above the crucibles during heating and by turning the crucibles and the moulds upside down so that the hot molten glass mixture flows into the moulds for subsequent solidifi-cation into solid glass disks of high quality, ready for analysis without further processing.  Various shapes of cru-cibles are disclosed.  This technique gives a better homo-geneity of the molten glass mixture within a shorter period of time.

Abstract: ALL TERRAIN VEHICLE AND METHOD OF OPERATING SAME            ABSTRACT OF THE DISCLOSURE   An all terrain vehicle has two vehicle units and an articulating link which interconnects the vehicle units in tandem. Each vehicle unit has a body and a pair of spaced crawler tracks which are powered for moving the respective vehicle unit. The articulating link has two longitudinally spaced apart pitch hinge assemblies, each of which cooperates with a respective vehicle unit to permit relative rotation therebetween about a horizontal pitch axis without interference between the vehicle units. Pitch swivelling means associated with one particular pitch hinge assembly can force relative rotation about the particular pitch axis between a particular vehicle unit and the link, so that one vehicle unit can be rotated forcibly relative to the other vehicle unit to negotiate marginal terrain. The remaining pitch hinge assembly can be either freely hinged to permit rotation about the remaining pitch axis or alternatively can have a similar pitch swivelling means. The vehicle also has a yaw hinge assembly for steering, and optionally has a roll hinge assembly to permit relative rotation about the link between the vehicle units, particularly for self-righting on hard terrain, and also for additional control and versatility. A single vehicle unit can be operable indepently of the other, but performance is increased considerably by utilizing at least two vehicle units in tandem connected by the articulating link. The vehicle combination can climb up or down vertical walls of limited height from hard terrain, or can negotiate a vertical wall disposed above water a height dependent on draft of the vehicle. The vehicle combination is self-righting from an inverted position on land or immersed in water.
