Abstract: ABSTRACT OF THE DISCLOSURE        The device for the testing through optical inspection of the cigarette ends comprises two probes made of optical fibres, which probes are arranged orthogonally with respect to each other. A first probe inspects the end surface of the cigarette being tested by directing against the said end surface a beam of light, and picking up the light reflected, the intensity of which depends from the end surface itself and from the distance of said end surface with respect to the said first probe. A second probe inspects a portion of the side surface of the cigarette comprising also the end being tested, by directing against the side surface a beam of light which provides for an inspection field of which only one part is interested by the clgarette end, and picking up the light reflected by the said side surface, the intensity of which depends from the length of the portion of cigarette end which is covered by the field of inspection and which depends from the actual length of the cigarette or from its axial positioning with respect to the probes. The light reflected by the end surface and the light reflected by the side surface are transformed into electric signals, which are compared in algebraic relationship the one with the other, and the resulting signal is used as a measure for the testing of the cigarette end.

Abstract: METHOD OF COMBUSTING NITROGEN-CONTAINING FUELS           Abstract of the Invention A method for combusting nitrogen-containing fuel by: combusting a first fuel-air mixture in the presence of a catalyst in a first stage, operated fuel-rich so that the amount of air in the first stage is substantially less than the amount needed for complete combustion; adding additional air to the effluent gas from the first stage to form a second mixture with an amount of air at least sufficient to combust fully the effluent from the first stage; and then combusting the second mixture in a second stage.  The first mixture is sufficiently fuel-rich, and the second mixture contains sufficient additional air, so that the combustion tempera-ture in the first stage is below a temperature that would result in any substantial formation of oxides of nitrogen or other fixed nitrogen compounds from atmospheric nitrogen present in the mixture being combusted, and the second stage temperature also is below that for substantial nitrogen oxide formation therefrom.  The method serves to suppress formation of nitrogen oxides from the nitrogen-containing compounds in the fuel.

Title: Dynamoelectric machine lubrication system and methods  of assembling the same
Inventor: CUNNINGHAM ELDON R
IPC: H02K5/16
Filed: 1977-07-15
Granted: 1980-08-12
Abstract: Abstract of the Disclosure An illustrated lubrication arrangement substantially prevents end leakage oil from flowing along the shaft to an oil thrower, and also causes end leakage oil to recirculate through wicking material to a feed wick which in turn feeds oil to a bearing clearance.  A feed wick includes a feeding portion that extends through a window in the bearing and contacts the shaft. This same wick includes recirculatory pick-up wicks that protrude into a capillary oil collection region at each end of the bear-ing.  The pick-up wicks have a smaller cumulative effective axial length than the feeding tab of the wick.  The pick-up wicks also contact the shaft, and they recirculate end leakage oil to the feeding tab because of gradients in oil content within the wick-ing that interconnects the pick-up wicks with the feeding tab. The pick-up wicks and feeding tab may actually be separate pieces, the capillary interstices of which communicate with each other.          The inner diameter ends of the bearing are chamfered according to prior practice to provide a capillary space that tends to circulate oil from the pressure side of the bearing to the unloaded side of the bearing.  By using the invention, filling up of the circumferentially extending capillary and ultimate creepage of end leakage oil is substantially reduced or eliminated because notches or windows at the ends of the bearings accommodate the pick-up wicks, the capillary action of which recirculates oil to the feeding tab.          Localized oil depletion causes oil to flow from the pick-up tabs to the more depleted region of the feed wick.  This depletion ensures that the feed wick will pick up the end leakage oil and recirculate it to the bearing.  In some applications, I can provide shield or barrier means that inhibit the supply of oil directly to the feed wick from an oil reservoir.  This can further ensure that oil supplied to the feed wick will be supplied from the wicking associated with the pick-up tabs.          The feed wick may be positioned within a bearing cavity so that it is pushed toward the shaft by its ends, and the material from which the feed wick is made will act as a beam which limits the amount of pressure between the shaft, feed wick, and pick-up tabs.  Moreover, the wick structure preferably is sway-backed to facilitate assembly of the wick in the bearing lubrication cavity, and to establish a re-oiling cavity.          In the practice of one preferred method, a feed wick combined with two pick-up tabs is moved axially along the out-side of a bearing holder, tilted in a first direction as a first pick-up tab crosses a feed window, tilted in the opposite direction just after the feed wick moves past a first bearing end notch, and then further moved in an axial direction while a leading end of the combined wick is cammed into a final position by part of the bearing housing of a motor end shield.

Abstract: ABSTRACT OF THE DISCLOSURE            A quick connect coupling is disclosed providing an integrally formed tube end assembly in which the wall of the tube is deformed to increase the diameter and is subse-quently roll formed to produce a pair of axially spaced peri-pheral grooves to receive a snap lock ring and a seal.  The inside diameter of the tube end within the grooves is substan-tially as large as the inside diameter of the remainder of the tube so that a substantial flow restriction does not result from the presence of the peripheral grooves. The material of the tube end is work hardened so that sufficient structural strength is provided even in the zone of the grooves.  A smoothly curved rib is also formed in the tube wall to cooperate with a lock ring to permanently connect a tubular nut to the tube end after the device is initially connected as a quick connect coupling.  The tubular nut is formed with a counterbore at its inner end to provide a radial wall and a cylindrical wall which receives the lock ring when the coupling is originally connected.

Abstract: ABSTRACT OF THE DISCLOSURE                The present invention relates to a videodisc containing stored information in the form of frequency modulated intelligence.  Prior art videodiscs have been made using recording procedures which record video signals in an amplitude varying with time format.  As a result, small inaccuracies in the recording process produce low quality signals when read by playback appar-atus.  Additionally, handling of the videodiscs of the prior art can easily destroy or adversely affect the quality of the reproduced signal.  The present invention overcomes the deficiencies by providing an improved videodisc having its information stored in a unique manner which permits faithful recording and reproduction of a video signal in the face of minor processing in-accuracies and handling of the disc.  In accordance with the invention, the videodisc contains information in the form of a carrier frequency having frequency changes with time varying from the carrier frequency.  The videodisc has an upper surface carrying a lineal series of indicia positioned in track-like fashion on the sur-face.  The indicia represents a frequency modulated intelligence signal.  The lineal series of indicia includes regions of alternately high and low directional reflectivity normal to the surface of the disc.  The regions of high directional reflectivity normal to the surface are areas of a metal coating on the disc, while the regions of low direction reflectivity normal to the surface are apertures in the metal coating.
