Abstract: Abstract A positioning apparatus (18) for boom structures (14, 16) is disclosed.  The positioning apparatus (18) is comprised  of  a  fixed  frame  assembly  (24)  mounted to vehicle (12), a slideable frame assembly (22) for vertical slideable movement with respect to fixed frame assembly (24),  and a pivotable frame assembly (20) for rotatable movement with respect to slideable frame assembly (22).          Boom structures (14, 16) are mounted on opposite sides of pivotable  frame  assembly  (20). A  system  including hydraulic  cylinders  (86,  77,  96) moves boom structures (14,  16) between transit and operational configurations, vertically  slides  slideable  frame  assembly  (22)  and pivotably rotates pivotable frame assembly (20).         The pivotal axis of the pivotable frame assembly (20) is above the center of gravity of the pivotable frame assembly  (20)  and attached boom structures  (14,  16)  to keep the boom structures (14, 16) pendulously stable when implement (10) strikes a bump in a field.  Springs (112, 118) and  shock  absorbers  (120)  recenter pivotal  frame assembly (20) relative to implement (10).  Plates (36, 70) transmit between the vehicle (12) and the boom structures (14, 16) force components parallel to the pivotal axis so as to protect pin (76) from extraneous stress.

Abstract: ABSTRACT OF THE DISCLOSURE         A change-speed apparatus for transmitting engine power to a set of driving wheels of a tractor via a main change-speed mechanism, an auxiliary change-speed mechanism and a forward-and-reverse travel selector mechanism.  The mechanisms are arranged in series in a fore-and-aft direction of a transmission case of the tractor and a shifter lever for the selector mechanism is disposed in juxtaposition to a main change-speed lever for the main change-speed mechanism.          Potentially dangerous high speed shifting in either a forward or reverse direction is prevented by a restraining mechanism that automatically inhibits simultaneous shifting of the main change-speed  mechanism to the highest speed, the forward-and-reverse travel selector mechanism to reverse and the auxiliary change-speed mechanism to a high speed range.

Abstract: METHOD FOR CONFIRMING REQUESTED TRANSACTIONS    BETWEEN SOURCE AND DESTINATION FILES OF      SPATIALLY RELATED DATA STORED IN AN INTERACTIVE TEXT PROCESSING SYSTEM                        Abstract An improved method is disclosed for providing to the operator of an interactive text processing system a displayed summary confirming the effect of requested changes to the field order in an existing file of spatially related data stored in the system prior to creation of new file.     The method involves simultaneously displaying to the operator on one screen the header portions of the existing source file and the destination file and causing the data in predetermined fields of each header to be displayed in a manner which is different than the manner in which the data in the remaining fields of said headers is displayed so as to manifest to the operator similar treatment by the system of the data in both headers which is similarly displayed.     The header portion of the source file is displayed such that those fields which are not to be copied into the destination file are reverse video displayed, while those fields which are to be copied to the destination file are in normal display.  The header portion in the destination file is displayed such that those fields which appear in the existing file and which are to receive data from the source file are displayed in normal manner, while fields which are not to receive data from the source file are reverse video displayed.  The resulting display than manifests to the operator those fields which will be copied from the source file to the destination file and provides the opportunity for the operator to confirm the correctness of the interactively entered instructions prior to actual creation of the new file.

Abstract: Case 3-13361/ARL 307/+         CANADA  PHOTOPOLYMERISATION PROCESS EMPLOYING COMPOUNDS CONTAINING ACRYLOYL GROUPS AND ANTHRYL GROUPS                   SUMMARY   In a three stage process, a layer of a liquid composition containing a compound (A) having in the same molecule both at least one (meth)acryloyl group and at least one anthryl group is exposed to actinic radiation so that the layer solidifies due to photopolymerisation of (A) through the (meth)acryloyl group(s), remaining, however, further photocrosslinkable. When desired, the solidified layer is exposed, as through a negative, to a substantially greater amount of actinic radiation, the parts so further exposed becoming more highly photocrosslinked through the anthryl group(s) and hence insoluble.  An image is produced which can be developed by means of suitable solvents.          Examples of (A) include 3-(acryloyloxy)-2-hydroxypropyl anthracene-9-carboxylate and its methacryloyl homologue.

Abstract: ADAPTIVE DIFFERENTIAL PCM CODING            Abstract An ADPCM coder converts a linear PCM input signal representative of PCM encoded speech or voice band data into a quantized n-bit differential PCM output signal.  Samples of the PCM input signal are delivered to a difference circuit along with a signal estimate of the same derived from an adaptive predictor.  The resultant difference signal is coupled to the input of a dynamic locking quantizer.  A quantized version of the difference signal is delivered from the output of said quantizer to an algebraic adder where it is algebraically added with the signal estimate.  The result of this addition is coupled to the input of the adaptive predictor, which in response thereto serves to generate the next signal estimate for comparison with next PCM sample.  The adaptive quantizer has two speeds of adaptation, namely, a fast speed of adaptation when the input linear PCM signal represents speech and a very slow (almost constant) speed of adaptation for PCM encoded voiceband data or tone signals.         The decoder operation is essentially the inverse of the coder, and similarly has two speeds of adaptation.

Once in position the modules are moved to an extended position and connections are made between the modules connectors and those on the side panels. The connectors provide low cost, high reliability, high density connections and facilitate close center to-center spacings between adjacent modules.
