Abstract: Capsules capable of controlled release of 2-chloro-N-(ethoxymethyl)-6'-ethyl-o-acetotoluidide herbicide enclosed in a polyurea capsule produced by the process comprising encapsulating waterimmiscible material within discrete capsules of polyurea without addition of a second reactant, whereby hydrolysis of an isocyanate monomer to form an amine takes place which in turn reacts with another isocyanate monomer to form polyurea, which comprises the steps of: a) providing, at room temperature, a dispersion of (i) a water-immiscible phase comprising the herbicide and an organic polyisocyanate in (ii) an aqueous phase comprising a solution of water, a surfactant and a protective colloid; and b) heating and maintaining said dispersion in a temperature range from about 40 °C to about 90 °C, whereupon said herbicide is encapsulated within discrete polyurea capsular enclosures. ?he microencapsulated composition performs comparably to non-encapsulated compositions of the same herbicide applied at the same application rates, while maintaining substantially lower mammalian toxicity compared with the nonencapsulated formulations.
Patent CA-2109284-A1 (CA)
Inventor: FOX ROBERT E
IPC: A01B63/22
Filed: 1993-10-26
Abstract: A hydraulic rockshaft control circuit which includes a three-way valve that normally operates the rockshaft is connected to the lift cylinder on a trailing implement.  A hitch lock valve connected to the rockshaft control valve maintains the rockshaft in a preselected position regardless of changes in pressure at the valve output.  The extend side of the lift cylinder is connected to the control valve output so that the tractor hitch control is used to operate the trailing implement cylinder.  To overcome the inability of the three-way valve to positively retract the trailing implement cylinder, a reducing/relieving valve is connected to the retract side of the cylinder and is adjusted to provide just enough pressure to retract the cylinder and raise the implement wheels from ground contact when the extend side is connected to return pressure.     A position feedback system on the implement is connected to the hitch control unit (HCU) on the tractor.  When the HCU senses a feedback signal from the implement, the HCU control mode changes from rockshaft control to trailing implement control wherein implement position is set and maintained in a manner similar to that for the conventional rockshaft control. A voltage readout from the feedback signal provides a visual indication of implement position.

Title: Board of lumber defect repair
Inventor: CORTESE THOMAS F
IPC: B27G1/00
Filed: 1994-04-05
Abstract: Defects in wooden boards, such as knots, knotholes or cracks, are repaired by forming an opening in the board at the site of the defect and forming a plug that fills the opening. In some forms of the invention the opening has a shape which interlocks the plug to the board. In another form of the invention, the plug is held in place by a transversely extending resilient member that is embedded in the plug and which is under tension which causes edge portions of the member to bite into or bear against the adjacent wood. Forming the opening includes cutting away bark encasement tissue that may adjoin the defect which encasement can cause a discoloration upon painting of the board and may eventually loosen. In some forms of the invention, cracks are repaired by making plural saw cuts along a crack to form the opening with the saw having a different angling relative to the board during each saw cut. In another form of the invention, the opening and plug extend between opposite surfaces of the board and have a width which increases at a plurality of spaced apart locations within the board and decreases at a plurality of alternate locations.
