Abstract: A mass flow grain monitor is located adjacent the upper end of the clean grain elevator assembly of a harvester and includes a load cell having a member that is subject to slight deformation under loads for use in generating an output signal that is proportional to the load. As the grain flow reaches the top of the elevator assembly, its direction is changed such that a centrifugal force is exerted by the moving flow that is proportional to the mass of the grain flow at that instant. Such centrifugal force is directed vertically against the deformable member of the load cell which is itself generally horizontally disposed when the harvester is on level ground so that the entire weight of the deformable member can be treated as tare and zeroed out of the system when it is calibrated with the harvester on level ground.

Abstract: The invention relates to an open cell, porous, selectively conductive member containing an elastomer that is reusable in use and preparation. The scaffold for the elastomer has conductive areas through conductive, z-axis pathways are provided which are electrically isolated from adjacent z-axis conductive pathways. The elastomer is non-adhesive and/or non tacky and allows for temporary connection of electronic components.

Abstract: A non-crosslinked endblocked polymer, comprising a preformed aqueous emulsion having a plurality of silanol-terminated polydiorganosiloxane particles, an endcapping silane having the formula R.sub.3 SiX where X is a hydrolyzable group, R is an alkyl group consisting of 1 to 7 carbon atoms, and an organotin catalyst. The composition results in a non-crosslinked polymer, unlike the polymers described in the prior art. It has been found that adding an endblocking silane having only one hydrolyzable group to a preformed polydiorganosiloxane emulsion results in endblocked polydiorganosiloxane molecules free of crosslinks between the polydiorganosiloxane chains.

Abstract: A crumb-like silicone rubber powder is uniformly dispersed in a polystyrene polymer using conventional equipment, such as a twin screw extruder, to provide a resin having up to a ten fold improvement in impact strength over the unmodified polymer. The novel silicone rubber powder of the invention is prepared by isolating the particles obtained from a polymerization of an unsaturated monomer in the presence of an aqueous emulsion of a unsaturated telechelic polydiorganosiloxane which has been prepared using an organotin curing catalyst and a dihydrolyzable grafting silane.

Abstract: The polymer latices of this invention are compositions formed by adding an unsaturated alkoxy silane and an initiator to a preformed emulsion polymer. The polymer latices have utility as protective surface coatings, adhesives, sealants and as vehicles for paint formulations.

Abstract: A non-crosslinked polymer, comprising a preformed aqueous emulsion having a plurality of silanol-terminated polydiorganosiloxane particles, a functionalizing silane having the formula R.sub.3-n Q.sub.n SiX where X is a hydrolyzable group, Q is an organic functional group which does not prevent a condensation reaction between X and a silanol-terminated polydiorganosiloxane molecule, R is a saturated monovalent hydrocarbon group of from one to six carbon atoms, and an organotin catalyst. The composition results in a non-crosslinked polymer, unlike the polymers described in the prior art. It has been found that adding a functionalizing silane having only one hydrolyzable group to a preformed polydiorganosiloxane emulsion results in functionalized polydiorganosiloxane molecules free of crosslinks between the polydiorganosiloxane chains.

The composition results in a non-crosslinked polymer, unlike the polymers described in the prior art. It has been found that adding a functionalizing silane having only two hydrolyzable groups to a preformed polydiorganosiloxane emulsion results in functionalized polydiorganosiloxane molecules free of crosslinks between the polydiorganosiloxane chains.

Abstract: An in-line gearshift mechanism for use with a powershift transmission of an agricultural vehicle. The gearshift mechanism includes a shift lever assembly, a shifter plate and a switch plate each separated by a plurality of spacers and secured as an integral unit to a frame portion of an interior of the agricultural vehicle. The shifter plate includes a plurality of in-line detent positions defining forward upshift, forward, forward downshift, neutral, reverse downshift, reverse and reverse upshift detent positions at which the shift lever may be positioned. The shift lever includes a gear encoder plate on which a plurality of switch activating elements are positioned. As the shift lever is moved between the above-mentioned detent positions, the switch activating elements selectively actuate selected ones of a plurality of reed switches disposed on the switch plate.

Abstract: A wide agricultural implement includes a pair of pivotally interconnected frame sections which allow the implement to better follow the contour of the ground. Each frame section is supported by vertically adjustable wheels and a master/slave hydraulic system is employed to adjust the wheels.

Abstract: A wide agricultural implement is provided with a pivoted swing hitch permitting endwise transport of the implement when supported on transport wheels which are raised and lowered by power means. A latch holding the hitch in its field working position is automatically released when the transport wheels are lowered to support the implement for endwise transport. The implement frame is made up of two subframes pivotally interconnected by the rock shaft on which the transport wheels are mounted and one of the latch parts is mounted on the rock shaft.

Abstract: A wide farm implement is provided with a swingable tongue which permits endwise to and from fields. A pair of transport wheels are provided for supporting the implement for endwise transport and the support wheels, on which the implement is supported during a field working operation, are raised so as not to interfere with endwise transport. In order to prevent the automatic lowering of a row marker when the support wheels are thus raised relative to the frame, a blocking valve is provided in the row marker hydraulic circuit which moves to its closed position when the tongue is moved from its field working position thereby preventing lowering of the row marker.

Abstract: A wide multi-row planter has a tongue which upon being disconnected at one point from the planter frame can be pivoted from its field position to an endwise transport position wherein the tongue and planter frame are within the tread width of the transport wheels. In its transport position, the tongue is secured to the planter frame by a releasable latch.

Abstract: An adjusting device permitting the operator of a planter to easily and accurately adjust the depth of planting by vertically adjusting the height of the planter frame through use of an adjustable spacer device in the support for the gauge wheels. The adjustable spacer has two main parts, one of which has a multiple series of axially spaced steps affording selective adjustment of the planter frame relative to the ground.

A press wheel (101) is provided to insure closing of the trench (39) over the seed.

Abstract: A video guidance system for visually displaying a row mark traced on the surface of a field during a previous traverse to the operator of a farm tractor pulling a planter has left and right row markers depending respectively from opposite outer sides of the planter for tracing row marks on the field; a video monitor on the tractor in the field of view of the operator; left and right video cameras mounted on the planter adjacent the outer edges thereof with the optical axis of each camera directed forwardly and inclined at a slight angle to the horizontal so that it images a substantial length of a row mark traced on a previous swath; and switch means for selectively connecting the video monitor to the left or to the right video cameras, whereby each scanning line of the video monitor raster creates a different spot on the image of the substantial length of the sensed row mark and such spots on successive scanning lines of the monitor raster are images of points spaced apart in said sensed row mark so the spot

Abstract: An agricultural planter (12) is provided with a hopper (37 or 137) which is adapted to receive a transverse partition wall (71 or 171) for dividing seed and chemical compartments (72, 73 or 205, 207). The chemical compartment (73 or 207) can be further divided into cells (74, 76 or 174', 176') by a longitudinal partition wall (77 or 177) whereby seed and two chemicals, such as a herbicide and an insecticide, can be dispensed from a single hopper (37 or 137) during a planting operation.
