Abstract: RADIALLY STAGED LOW EMISSION CAN-ANNULAR COMBUSTOR          ABSTRACT      A burner construction in which staging of combustion is obtained by a primary pressure-atomizing nozzle having a low spray angle to maintain combustion within a central core of the combustor, and a secondary fuel aerating nozzle delivering fuel in a hollow cone configuration surrounding the primary fuel spray for combustion in an annulus between the central core and the wall of the combustor.  Although most of the air for primary combustion is supplied with the fuel nozzle, addi-tional air may be introduced at the upstream end of the combus-tor by high penetration jets that enter the central core and additional air for secondary combustion is introduced by one or more rows of holes in the combustor wall near the upstream end.

The coating is produced by radiation curing.  A first monomer selected from the group consisting of triacrylates and tetraacrylate mixed with a second monomer having an N-vinyl imido group, preferably an N-vinyl lactam, such as vinyl pyrrolidone or vinyl caprolactam.  The monomer mixture is substantially oligomer-free and if the radiation is ultraviolet light, a photoinitiator, preferably p-phenoxydichloro acetophenone or dimethoxyphenyl acetophenone, is included in themixture.

Abstract: The tapping drill having a drive shaft driven with an alternating rotational movement, comprises, disposed between this drive shaft and the tool carrier, a ratchet mechanism capable, at will, of transforming the alternating rotational motion into a rotating movement by successive impulses in one direction or the other. The ratchet mechanism comprises a dog with spring extending through an annular member integral with the tool carrier, this dog bearing in an axial groove formed in an interior member integral with the drive shaft, in which interior member there can successively be distinguished three parts: a first part comprising solely the groove; a second part in which the groove is flanked by a cut-away on one side, a third part in which the groove is flanked by a cut-away on the other side, the dog being able to slide freely into the cut-aways and to be displaced along the groove. The dog is displaced along the groove by a control member bearing with play in an annular groove formed in the annular member.

Abstract: PATENT APPLICATION of GEORGE D. KNEIP, JR. AND MARVIN H. ANDERSON                   for IMPROVED CRYOSTAT WITH EXTERNAL REFRIGERATOR         FOR SUPERCONDUCTING NMR SPECTROMETER              Abstract of Disclosure An improved cryostat for the superconducting magnet of an NMR spectrometer comprises a nested structure of isothermal shells surrounding a thermally conductive central reservoir of substantially spherical shape containing liquid helium in which the superconducting solenoid remains operational when only partially immersed.  A radiation shield surrounding the central reservoir is cooled by the boil-off of escaping helium vapor.  The radiation shield is enclosed within an isothermal shell maintained at the temperature of liquid nitrogen by thermal contact with a liquid nitrogen reservoir disposed above the region of the central reservoir and shielded therefrom by a wall of the isothermal shell.  An outer radiation shield surrounds the liquid nitrogen reservoir and associated isothermal shell and the outer radiation shield is maintained at a temperatures of the order of 180°K by an external refrigeration facility.  A hermitically sealed containment vessel forms the outer wall of the cryostat and provides a port for evacuating to a very low common pressure all the interior spaces between adjacent nested structures.  The spacing between adjacent nested surfaces is maintained by a novel internal mechanical bracing system of low thermal conductivity comprising polyester cords disposed under tension between adjacent shells.                           -i-

Abstract: APPARATUS, AND A METHOD, FOR REMOVING TERMINAL PINS FROM A BANDOLIER Abstract of the Disclosure Terminal pins, mounted on bandoliers, for treatment and other purposes, are removed rapidly from the bandolier, without bending or changing the end-to-end orientation.  The bandolier is pulled at speed through a tool having a slot for the bandolier, a rib extending into the slot and having a chamfered leading or front edge.  The chamfered end enters a clearance between pin and bandolier, the pin being forced away from the bandolier while the bandolier is held down by the rib.  The pins are removed at high speed and hit an inclined surface extending over the chamfered end to be deflected sideways through a passage.  The pins exit from the passage and can be fed to an assembly machine, loading apparatus or storage containers.  Air may be blown through the passage to assist in removing the pins.                             - i -

Abstract: RCA 74,698 ABSTRACT         The input terminal of a voltage follower is coupled to a point of reference potential via a first capacitor.  A second capacitor is alternately connected across a source of input signals and connected in parallel with the voltage follower during mutually exclusive time intervals whereby an output voltage is produced across the first capacitor proportional to a differential mode component of the input signal.  The arrangement is such that internally generated noise is suppressed, very low frequency breakpoints (lag) may be realized with practical element values and there is substantially no tendency toward saturation in the presence of high frequency input noise components.

Abstract: ABSTRACT OF THE DISCLOSURE A novel method is provided herein for manufacturing a case-harden-able, rotationally symmetric, hollow shaft, made  from at least two shaft parts each of which parts is produced by the method of cold extrusion, the shaft parts being joined with each other by welding in regions of constant shaft diameter is provided herein.  It includes the first step of forming the parts destined to be the two opposite shaft end parts by cold extrusion, each part having an axial cavity closed at one end thereof and constituting one of the ends of the hollow space in the shaft.  Then any other, inter-mediate shaft part is likewise formed by cold extrusion, at least one of the shaft parts consisting of at least two stepped regions, each being of constant diameter, the diameters of these regions being stepped down toward a closed shaft end, the configuration of the internal wall of the hollow space in the hollow shaft corresponding substantially to the configuration of the outer shaft surface.  Then the shaft parts are friction welded to-gether, with the weld between adjacent shaft parts being located in a joint plane, with the cavities of the adjacent shaft parts opening in the joint plane, and the cavity of at least one of the adjacent shaft parts having its largest diameter in the joint plane.  In this way, a finished shaft having a continuous hollow space in its interior, sealed at all sides, is obtained.  The lightweight shafts manlufactured by this method are easily manufactured and yet have strength properties guaranteeing safe operation. The method is particularly useful for manufacturing shafts, the diameter of which become smaller towards their ends and in which the total material used is not wasted in a substantial amount of wasteful turnings or the like.

Abstract: ABSTRACT OF THE DISCLOSURE An input module and a sample and hold circuit cooperate to produce sample values representative of the instantaneous magnitudes of three-phase line voltages and line currents delivered to a load by a power distribution system.  The  sample values  representative  of  the  line voltages are input directly to a multiplexer.  The sample values representative of the line currents are input to the multiplexer both directly and through ranging ampli-fiers.  When the sample values of the line currents are below a predetermined magnitude, the sample values ampli-fied by the ranging amplifiers are used, thus increasing the accuracy of the metering system.  The sample values are  input to  an analog-to-digital  converter  where  the sample values are digitized.  A control circuit calculates a plurality of indica of the AC electric energy quantity delivered to the load from the digitized data.  An output module is responsive to the control circuit for display-ing,  recording or transmitting the calculated indica.  A timing circuit times  out  a predetermined  sample  timer interval.  At the end of the interval the control circuit produces new sample values and resets the timing circuit. The timing circuit is constructed so as to recognize a plurality of failure modes  of  the  control  circuit  and reset the control circuit in response thereto thus improv-ing the reliability of the metering system.
