Abstract: An apparatus for monitoring the depth of tread on a tire being buffed includes a sensing device, for example, a magnetic sensor, mounted to a reciprocating motion carrier. The carrier is driven by a drive wheel that is in contact with the tire being buffed. The carrier is movably mounted to float over the surface of the tire, that is, accommodate variations in the tire surface, with a guide wheel following the tire surface to maintain the sensor at a constant distance from the tire surface. The sensor on the carrier reciprocally traverses the crown of the tire as the tire rotates to obtain actual values for the thickness of the rubber above the belts over the whole surface of the crown.

Abstract: An improved network interface unit (NIU) for remotely monitoring and testing the performance of DS1 telephone circuits, installed on the network side of an interface between customer premises equipment (CPE) and equipment provided by the network provider. The inventive NIU is used to non-intrusively collect and transmit full-time performance monitoring data to the network provider. The inventive NIU provides continuous and non-intrusive performance monitoring of DS1 transmission systems. With the inventive NIU installed at the interface between the customer's CPE and the LECs' equipment, network service providers are alerted to potential problems before they adversely affect the service provided by the network providers to their customers. The inventive NIU enables a network service provider to quickly and non-intrusively determine whether a problem exists in the equipment provided by the network provider or in the equipment on the customer's premises.

Abstract: A flywheel slip clutch is provided for use with implements such as agricultural balers. The flywheel slip clutch includes a plate mounted on a hub which is fixed to rotate with the input drive shaft of an implement. The plate is connected to the PTO drive line and clutch of a tractor. A flywheel is rotatably mounted on the hub, and a friction disc is interposed between annular surfaces of the plate and the flywheel. During normal operation, the torque from the tractor PTO drive line and the torque generated by the flywheel are delivered to the input shaft of the implement. In the event of an overload condition on the implement input shaft, the tractor PTO clutch disengages and the flywheel spins out disengaging itself from the friction disc which is connected to the plate. This prevents damage to the implement without utilizing a shearbolt between the flywheel and the hub.

Abstract: Apparatus is disclosed for adjusting the packer assembly of an agricultural baler. The apparatus includes a control link or rod having one end thereof connected to a trunnion which is rotatably mounted between the forks of the packer assembly. A support member or clevis rotatably supports another trunnion that is connected to the other end of the control link. An adjusting device or knob is connected to the support member by a screw to move the support member to different positions in order to adjust the penetration of the packer forms into the bale case of the baler. An important feature of the disclosed apparatus is that the adjusting device or knob remains stationary relative to the bale case of the baler during movement of the packer forks. This feature facilitates adjustment of the packer assembly when the baler is operating.

Abstract: A single-ended compact fluorescent lamp having an envelope that is partitioned or of multi-U-bent shape and defines a tortuous arc path is combined with a plug-in ballast module which is elongated in a lateral direction but has a low profile and a narrow width. The resulting decrease in the overall height dimension of the unit formed by the mated lamp and module, together with the narrow width of the module, permit the unit to fit within the harp component of a table lamp or similar lighting fixture and be used as a replacement for an incandescent lamp. The screw-in socket of the lamp fixture is provided with a threaded adapter plug which enables the lamp-ballast unit to be plugged into the adapter after it has been inserted between the spaced support rods of the harp component.

Abstract: For fluorescent lamps which use a double layer of phosphor with manganese-activated zinc silicate phosphor in the overlying layer, a small predetermined amount of finely-divided antimony oxide is added to the first phosphor layer coating paint which, after application, is lehred at a temperature which is sufficient to volatilize the organic binder but which is insufficient to volatilize more than a minor proportion of the antimony oxide. Thereafter, the second phosphor layer coating paint which includes the zinc silicate is applied over the first-applied layer and the applied second layer coating paint is then lehred at a temperature which is sufficient to volatilize an appreciable portion of the residual antimony oxide in the first-applied layer to cause the volatilized antimony oxide to contact the zinc silicate.

Abstract: A fluorescent lamp of high brightness and compact size is provided by forming the envelope from vitreous tubing that is bent upon itself in such a manner that the envelope has either five or seven U-shaped sections which are disposed in tridimensional array and define a single convoluted discharge channel. The U-shaped sections are so oriented that the tubular legs of the U's are positioned in side-by-side columnar relationship with each other and the sealed ends of the tubing are located adjacent one another. The lamp thus has an arc length that is more than six or eight times as long as the overall height dimension of the convoluted envelope and generates light in a very efficient manner.

Abstract: Fluorescent lamps have a predetermined correlated color temperature and a combined efficiency and good color rendition of illuminated objects. The lamps utilize a two-layer phosphor coating comprising a layer coated onto the envelope interior surface and formed of a very high performance three-component blend which includes a blue-emitting phosphor, a green-emitting manganese-activated zinc silicate phosphor, and a red-orange emitting phosphor, all mixed in predetermined amounts and relative proportions to provide an emission of approximate predetermined x-y coordinates. Under some conditions, the phosphor blend when used as a single layer is subject to depreciation of the light output of the green component, particularly in the vicinity of the lamp electrodes which results in color shifts which are objectionable from an aesthetic standpoint.

Abstract: A fluorescent lamp having a triple-U-bent tubular envelope is combined with circuit means, a translucent protective cover and a threaded base member to provide an efficient screw-in type lamp unit of high brightness and long life that is compact enough to be used as a direct replacement for incandescent type lamps in fixtures designed for residential and commercial lighting. Various structural arrangements for including the ballast and starter components of the energizing circuit as integral parts of the compact lamp unit, despite the stringent space limitations, and also venting the cover and base structures to provide convection cooling of the compacted electrical components are also disclosed.

Abstract: A compact fluorescent lamp of high brightness is provided by a partition structure within the lamp that divides the tubular envelope into a plurality of interconnected sectors and also defines a core chamber that is not traversed by the discharge and is of predetermined size relative to the envelope. The core chamber serves both as a conduit or passageway for the lead-in conductors of one of the electrodes and as a means for enhancing the efficacy of the lamp by displacing the discharge outwardly toward the envelope walls and thus minimizing the "light entrapment" effect deep within the envelope and the corner portions of the partition structure. The use of the core chamber as a lead wire conduit permits the electrodes to be located at the same end or opposite ends of the envelope--thereby providing "odd-pass" discharge lamps of single-ended construction or "even-pass" discharge lamps of double-ended construction that can be readily fabricated.

Abstract: The light output of a compact fluorescent lamp is enhanced by providing the envelope with a phosphor-coated partition assembly which has a plurality of panel segments that divide the envelope interior into a series of interconnected sectors and also define a centrally-located core chamber that is closed to the discharge. The size of the core chamber is correlated with the size of the envelope in such a manner that the discharge is displaced from the center of the envelope toward the phosphor-coated walls thereof, thus reducing losses due to the "trapping" of light deep within the envelope interior and concurrently increasing the relative amount of ultraviolet radiation that reaches and excites the phosphor coating on the envelope wall. The efficacy of the partitioned fluorescent lamp is accordingly increased.

Abstract: The tubular envelope of a double-ended fluorescent lamp is provided with a partition assembly of sheet metal or other rigid material that is inserted into the envelope in the space between the electrodes and defines a single discharge channel which forces the arc to traverse the envelope an odd number of times in retroverted fashion, thus reducing the size of the lamp and providing a concentrated light source of high brightness. The partition assembly consists of a number of joined panels that radially extend from a common axis to the envelope walls and divide the interior of the envelope into an odd number of sectors that are interconnected and form a continuous discharge channel. Diaphragm components are fastened to each end of the partition assembly and laterally extend across the interior of the envelope to prevent the arc from bypassing the partition assembly or any of its planar segments.

Abstract: The envelope of a fluorescent lamp is provided with a partition assembly of sheet metal or other rigid material that is inserted into the envelope and forces the art discharge to follow a tortuous path which is longer than the envelope, thus reducing the size of the lamp and providing a concentrated light source. The inherent tendency of the arc to bypass the partition by seeking and passing through small gaps or crevices between the envelope wall and the mating edges of the partition assembly is prevented by providing the longitudinal edges of the partition assembly with short laterally-extending flanges that are seated against or closely overlie the envelope wall. The resulting lengthening of the arc-leakage paths through such gaps or crevices creates a "barrier" along the envelope-partition interface which cannot be breached by the arc.

Abstract: The envelope of a single-ended fluorescent lamp is provided with an inserted partition assembly that forces the arc discharge to follow a tortuous path which is longer than the envelope, thus reducing the size of the lamp and providing a concentrated light source which is suited for use in lighting fixtures that are designed for incandescent type lamps. The inherent tendency of the arc to bypass the partition is overcome by seating the end of the partition assembly against a soft gasket of porous material (preferably fibrous in structure) that is located at the sealed end of the envelope and constitutes a barrier to the discharge which blocks the direct arc-path between the adjacent electrodes. The porous gasket is part of a diaphragm assembly and, since it is permeable to gases and vapors, it does not interfere with the evacuation of gaseous impurities and water vapor from the envelope when the lamp is being manufactured.

Abstract: A single-ended fluorescent lamp having a partitioned envelope is coupled to a threaded screw-in type base and a module that contains a miniaturized electronic circuit which permits the lamp to be started and operated on direct current from an AC power source. The resulting compact fluorescent lamp unit can thus be used as a direct replacement for incandescent lamps in fixtures that are designed for residential and commercial lighting. Cataphoretic pumping and accumulation of the mercury vapor in the vicinity of the cathode during DC operation and short-circuiting of the partition by the arc discharge are both prevented by a diaphragm assembly at the electrode-end of the envelope which includes a porous gasket of fibrous material that is permeable to mercury vapor but constitutes an impenetrable barrier to the arc.
