Abstract: ABSTRACT OF THE DISCLOSURE       A retractable in-row tiller device is adapted for mounting on a movable vehicle and for tilling the ground around and between objects in a row. An outrigger arm with a rotary tiller mounted on its distal end is ?etracted inwardly and extended outwardly by a trapeze type control arm which amplifies the velocity and magnitude of reciprocal motion produced by a hydraulic ram to move around and avoid objects encountered in the row. Both manually and automatically operable controls are included respectively to allow an operator to retract and extend the tiller out of and into the row as desired and to cause the tiller to be retracted and extended out of and into the row automatically upon encountering an object in the row. Manual control is also provided for the operator to override the automatic retraction control.      A lift mechanism for lifting the tiller out of the ground and a rotary drive for rotating the tiller are interrelated such that the vertical lift force is variable in relation to the force required to rotate the tiller. The ratio between the lifting force and the rotary drive is adjustably variable to effect auto-matic depth control for ground penetration.      An additional feature includes a positive depth control plate for the rotary tiller head, and alternative embodiments include a pair of parallel spaced apart linear chain tillers which move in opposite directions transverse to the forward motion of the vehicle with one chain tiller following the other.

Fastening means includes a metal pin rigidly connected to the base surface and has a shank extending through the sheeting and head means on the pin bearing on the engagable marginal areas. The marginal areas are separated from the shank by an expansion gap to allow movement of the sheeting parallel to the base surface. The shank has a rugose surface, provided with lateral projections intervened by recesses, and the head means is a cap member having a body of resilient material of mushroom-like crosssection provided with a central opening by which it is forcibly impaled on the pin and having a planar base slidably engaging the marginal areas. The aperture means may be openings provided within the peripheral margins of the sheet or the marginal areas of a pair of adjoining sheets making up the sheeting where the aperture means is a gap between the peripheral margins of respective sheets or both. In a preferred structure, the rugose part is made up of a series of frusto conical rings having undersurfaces perpendicular to the axis of the pin providing annular acute cornered ribs and intervening grooves.

Abstract: CONTINUOUS SPEECH PATTERN RECOGNIZER            Abstract A speech analyzer is adapted to recognize a speech pattern as a string of reference words.  A set of signals representative of the time frame sequence of acoustic features of each reference word is stored. A set of signals representative of the time frame sequence of acoustic features of the speech pattern is generated.  At least one string of reference words is produced from the speech pattern and reference word acoustic feature signals and the speech pattern is identified as one of the reference word strings.  The reference word string generation includes identifying successive reference word levels and assigning a speech pattern segment to each level.  At each level, the assigned speech pattern segment features are time registered with the features of each reference word to produce speech pattern segment time registration endframe signals and time registration correspondence signals for each reference word.  Reference word strings are produced responsive to the time registration endframe and correspondence signals of the levels.

Abstract: AUTOMATIC CONTROL LINKAGE FOR ROUND BALE WAGON    ABSTRACT OF THE DISCLOSURE        A control linkage for a round bale wagon is disclosed wherein the operation of the mechanism for conveying bales laterally across the load bed to form a row of bales and the operation of the mechanism for pushingly advancing a row of bales rearwardly on the load bed is automatically, sequentially controlled in coordination with the operation of the mechanism for picking up bales in the field and elevating them onto the load bed.  The control linkage includes a p2' r of pivotally connected links pivotally interconnecting the frame of the bale wagon, the control frame 'or the hydraulically powered cross conveyor and the pusher advance mechanism, and a delay valve for coordinating the operation of the cross conveyor relative to the bale pickup mechanism, one of the links having a free end movable within a fixed path.  An over-center linkage interconnecting the cross conveyor and the pusher advance mechanism controls the movement of the free end of the one link and, thereby, the positioning of the control valve between a cross conveyor mode and a pusher mode.  Movement for the pair of links to position the hydraulic control valves is provided via a connectirlg link transferring motion thereto from the bale pickup mechanism.
