Abstract: ABSTRACT OF THE DISCLOSURE           A method of producing an optical waveguide by melt-drawing a transparent glass rod which has been produced by collapsing a porous glass rod after being doped with a dopant material, said dopant material being deposited on the surface of the micro pores in order to enhance the refractive index of the collapsed glass rod.  A waveguide having higher mechanical strength and lower transmission is attained by drawing said glass rod at a temperature very close to the melting point of the outermost portion of the fiber without causing any over-melting or bubbling in the core portion, said drawing process being facilitated by matching the viscosity and characteristics of the outermost lower-refractive-index portion to those of the central higher-refractive-index portion.

Such rack/ track assemblies have longitudinal rails on their tops for the rollers and longitudinal racks secured to the bottoms of the rails.  The racks are engaged by under-lying walking pinions journaled in the carriage and positioned directly beneath the rollers.  In a modification, the combined rack/track assemblies include bottom rail surfaces in addition to top rail portions, and bottom rollers are employed in addition to the pinions and top rollers.  In another modification, the carriage is sup-ported by an I-beam the bottom flanges of which constitute the tracks, a single rack being secured to the underside of such bottom flange.           The carriage has a set of accessible spur gears journaled at its rear wall beneath a cover, including a driving gear keyed slidably on a shaft driven by a sta-tionary motor at the rear of the beam, the gear set being connected by a shaft which projects into the carriage to internal gears in the carriage which drive the walking pinions, one of the accessible rear gears being drivingly connected to the lance tube to rotate the latter as the lance tube is moved longitudinally by the carriage.

Abstract: ABSTRACT OF THE DISCLOSURE         A  drop center livestock trailer is provided with a deck which is vertically adjustable within the trailer body to two separate positions for accommodating various forms of livestock and freight.  A sectional gate structure which extends for either the full or a part of the trailer trailer width is incorporated in the trailer for assuming a first position in which it acts as a gate limiting the movement of livestock in that trailer and a second position wherein it supports a ramp for facilitating the loading and unloading of the livestock.  The ramp is pivotally attached to one end o  the movable deck and is supported by a lower section of the sectional gate structure.  The ramp is allowed to drop from its normal horizontal position to an inclined position by moving the lower section of the gate structure to an inclined position.  Connected to the lower gate section to an upper gate section which is pivotally connected to the side walls of the trailer.  The upper gate section is connected to the lower section by a connecting rod so that the lower section is rotated from its normal vertical position to the inclined position.  The connecting rod consists of two telescopingly related portions and is capable of assuming two positions for adjusting the effective length thereof. In this manner, the angle of inclination of the lower section of the gate structure is adjustable for supporting the ramp when the movable deck is in each of the two positions which it is capable of assuming.
