Abstract: STEERING SYSTEM FOR A TRAIN OF RAIL-LESS VEHICLES                ABSTRACT OF THE DISCLOSURE    A steering system for use with a multiple vehicle train permits tracking without rails of one vehicle after another.  This system is particularly useful for moving conveyor systems into and out of curved paths of room and pillar underground mine installations.  The steering system features an elongated steering bar pivotally connected to each of adjacent vehicles at end portions of the bar per-mitting angular orientation of each vehicle in respect to the steering bar and other vehicles.  Each end portion of the steering bar is linked to the near pair of vehicle wheels through wheel yoke pivot arms about king pin type pivots.  Movement of the steering bar about its pivotal connection provides proportional turning of the wheels to effect steering and tracking of one vehicle following another in both forward and reverse directions.

Abstract: ABSTRACT      An alignment target for an electron-beam direct write system is formed on a wafer of semiconductor material.  First, a layer of silicon oxide is formed on a surface of the wafer.  Then a layer of silicon nitride is formed on the oxide.  Next, an opening is etched in the nitride layer to expose a surface portion of the oxide.  The surface portion of the oxide is then etched to form a hole in the oxide.          The hole is formed such that the oxide layer is undercut beneath the nitride layer such that a cantilevered nitride overhang is formed around the perimeter of the hole.  A layer of aluminum is then deposited over the nitride layer.

Abstract: ABSTRACT EMERGENCY LOCKING REEL FOR BELTS        An emergency locking reel for a safety belt and being of the kind having a frame which is securable to a support, a spool rotatably mounted on that frame, and locking means operable to prevent rotation of that spool in a belt unwinding direction.  The locking means comprises a toothed ring secured to the frame and a pawl rotatable with the spool and movable relative thereto to engage the ring.  According to the invention, an inertia plate is provided separate from the pawl and is mounted on the spool spindle for limited relative rotation.  A ratchet wheel is connected to the pawl for rotation therewith and carries a detent which responds to relative rotation between the wheel and inertia plate to stop rotation of the wheel and thereby cause the pawl to engage the ring.  A spring resists that relative rotation between the wheel and inertia plate.  The housing for the locking means is symmetrical about a plane which contains the spindle axis and a sensor responsive to vehicle deceleration is also located on that plane.  The sensor is securable to the housing in any of a plurality of positions without disturbing the aforementioned symmetry.  Furthermore, each tooth of the locking ring is symmetrical about a plane containing the spindle axis.  An end plate of the housing has, as integral parts, a bearing for the spindle and locating means for the locking ring and sensor respectively, thereby simplifying assembly of the reel.  A wedge-type retainer secures an end of the belt to the reel by locating in a slot of the spool and clamping the belt in three separate zones.
