A baler has improved linkage for controlling a needle safety latch mechanism being supported on the baler and biased for movement from a retracted position to an extended position for stopping the reciprocation of a plunger within a bale case on the baler if the timing between the plunger and a needle-carrying member on the baler is disrupted and the plunger moves on a working stroke when the needles are projected across the bale case and the path of the plunger. The improved linkage includes an elongated rigid member extending along the bale case and pivotally interconnected at one end to the latch mechanism and a link pivotally coupled adjacent one of its ends to pivot means which also pivotally mounts the needle-carrying member. The link adjacent an opposite one of its ends is pivotally coupled to an opposite end of the elongated member. Also, the link includes a portion disposed in the path of movement of the needle-carrying member. The latter member engages a resilient, rubber-like element on the link to hold the link at a first position when the needle-carrying member is at its home position and thereby, via the elongated rigid member, holds the latch mechanism at its retracted position. As the needle-carrying member moves away from its home position toward the bale case to project the needles across the bale case, it allows the link to pivot to a second position as the bias of the latch mechanism moves it to its extended position upon the release of the link.

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. To protect the green-emitting component of the high performance blend, there is provided over the phosphor blend layer a very thin layer of finely divided phosphor which is very stable and which has an emission of approximately the same x-y coordinates as the high performance phosphor blend layer. The resulting lamp has overall improved performance from an aesthetic standpoint.

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.

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.

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. Alternatively, the threaded plug is made a part of the module and constitutes an integral threaded base member which permits the lamp-ballast unit to be screwed directly into the fixture socket after the harp component has been temporarily removed.

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. The size-correlation is rather critical and must be such that the maximum cross-sectional dimension of the core chamber at a given location is from about 25% to about 85% of the maximum cross-sectional dimension of the envelope at the same location and optimum results are obtained when this parameter is around 50%. The improved fluorescent lamp is thus especially adapted for use as a substitute for incandescent lamps in various types of lighting fixtures where space is limited and a light source of high brightness is required.
摘要:
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. Short-circuiting of the arc around the end portion of the partition assembly is prevented by a diaphragm component comprising a transverse panel member that is secured to the partition assembly and has a peripheral flange that makes a snug fit with the side walls of the envelope. The diaphragm component can also comprise a compliant pad-like gasket of porous material that is held in nested relationship with the end portion of the partition assembly by retaining means.
