Abstract: A linear actuator for a rotating shaft assembly includes a cylinder and a piston arranged within a cavity defined by the cylinder. Faces of the piston delimit first and second chambers within the cavity. A rotatable shaft fixed to the piston defines a first main passage in fluid communication with the first chamber and a second main passage in fluid communication with the second chamber. A pressure delivery body rotatably fixed to the rotatable shaft defines a first delivery passage in fluid communication with the first main passage and a second delivery passage in fluid communication with the second main passage. A passage isolation system selectively isolates fluid communication between the first delivery passage and the first main passage and fluid communication between the second delivery passage and the second main passage. A pressure limiting system selectively blocks fluid communication through the first and second main passages.

Abstract: A linear actuator for a rotating shaft assembly is provided that includes a cylinder member and a primary piston arranged within a cavity defined by the cylinder member. A first face of the primary piston delimits a first chamber within the cavity and a second face of the primary piston delimits a second chamber within the cavity. A rotatable shaft is fixed to the primary piston and defines a first main passage in fluid communication with the first chamber and a second main passage in fluid communication with the second chamber. A pressure delivery body is rotatably fixed to the rotatable shaft and defines a first delivery passage in fluid communication with the first main passage and a second delivery passage in fluid communication with the second main passage.

Abstract: An extrusion apparatus includes first and second die body portions each having a main body and a lip interconnected with the main body wherein the die body portions are joined such that a single die outlet is formed between and bounded by the lips. The apparatus also includes suitable structure for moving the lips to adjust the die outlet.

Abstract: A seeding assembly (20) for attachment to a cultivating or seeding tine (21). The seeding assembly (20) includes a seed tube (52) movably attached to the tine (21) by parallel linkages (53, 54). A wheel (63) is attached to the seeding tube (52) to regulate the height of the lower extremity (53) of the seeding tube (52) so that a seed is delivered to a seed bed (54) prepared by a closing tool (58) located forward of the seed tube (52).

Abstract: Various silicone materials, which have a low order of toxicity to fish, birds, and wildlife; and which slowly degrade to carbon dioxide and silicon dioxide in the environment, may be used to treat local soils to make them permanently oleophillic. These soils can then be used to minimize, consolidate, and clean up oily spills. Because local soils are used and only minor amounts of chemicals are required, the cost of cleanup is drastically lowered while response time is much quicker.

Abstract: What is disclosed are food compositions which contain a polyorganosiloxane fluid as a fat substitute and an anti-anal leakage agent. The anti-anal leakage agents comprise C.sup.12 -C.sub.24 essentially saturated fatty acids or edible, digestible sources thereof; non-degradable, water insoluble fibers of plant origin; and silica.

Abstract: The present invention relates to the use of crosslinkable silicone materials to coat botanic seeds, seedlings, meristematic tissue and plant embryos for their protection and to promote germination. The crosslinkable silicone materials are coated onto the seeds, seedlings, meristematic tissues or plant embryos and crosslinked to cure them. The silicone coatings of the present invention on the surface of the seeds, seedlings, meristematic tissues or plant embryos provide antifungal protection and can be used to carry entrapped plant adjuvants to the site of germination. The crosslinked silicone coatings are permeable to water vapor and oxygen and allow sunlight to pass through to the germinating seed.

Abstract: A jump mechanism for a plough having a frame and at least one digging shank, the jump mechanism includes a main draw bar pivotally coupling the shank to the frame so that the shank can pivot about each end of the bar and a movement control bar also pivotally coupling the shank to the frame so as to govern pivoting of the shank about one end of the main bar relative to the pivoting of the main bar relative to the shank.

Abstract: A plough shank having a rounded leading edge portion with a leading surface, a trailing portion, a web connecting the trailing and leading portions, an attachment mechanism at the top of the shank to enable attachment of the shank to a plough frame so that the leading surface is inclined by 60.degree. to 80.degree. to the horizontal, and a construction at the bottom of the shank to enable the attaching of a digging point thereto. The attachment mechanism may comprise a lobe integral with the shank and received in a clamp for attachment to a tool bar. The clamp may include two pivotably connected portions with an interconnected spring or hydraulic system.

Abstract: A plow shank has a digging blade attached to the lower extremity thereof by an adaptor. The digging blade has an inclined upper arcuate surface to which the adaptor is releasably secured. The adaptor is also releasably secured to the lower extremity of the shank, such that the blade is located below the lower extremity of the shank to enable the blade to present a low forward facing rounded profile.

Abstract: A vibrating device having a mass rotated about a first shaft while the first shaft is rotated about a second shaft.
