摘要： A material eject system includes an ejector mounted to a bed of a vehicle which is movable between a rear end and a forward end of the bed for ejecting material from the bed. The ejector is powered by a cylinder having different fluid volumes depending on the direction of motion of the cylinder. Two pumps having flow rates matching the different fluid volumes of the cylinder are used to power the cylinder in the different directions.

摘要： The invention is a sliding shield between the cab end and engine end of a bi-directional or articulated tractor. A sliding member is pivotally attached to the flared shield support on the cab end. The sliding member has a slot on which permits it to be slideably attached to the flared end shield. There are a pair of opposing walls perpendicularly affixed to the shield member. One wall has an aperture with a removal door attached. The sliding member covers a pair of universal joints and a connecting transfer shaft. Access to a grease fitting on the transfer shaft may be gained through the door to allow lubrication.

摘要： A chair control mechanism is provided for use on a chair having a separate seat 14 and backrest 16 that move with respect to a base 12 of the chair. The mechanism 22 includes a housing 26 supported on the base, and brackets 28, 30 secured to the seat and backrest. The seat bracket 28 is supported on the housing for pivotal movement about a horizontally extending front pivot axis 68 between an upright position and a reclining position, and the front pivot axis is located adjacent the front end of the housing. The backrest bracket 30 is supported on the housing for pivotal movement about a horizontally extending rear pivot axis 80 that is located rearward of the front pivot axis. A mechanical linkage 70, 78 is connected between the brackets at a position spaced rearward of the rear pivot axis relative to the housing for transmitting pivoting movement between the brackets, and a spring assembly 32 is connected between the housing and the backrest bracket for biasing the seat and backrest toward the upright position. A forward travel-stop control assembly 38 is provided on the mechanism for adjusting the forward most position of the seat and backrest, as is a tilt control assembly 36 which permits the seat and backrest to be locked against tilting movement. The tilt control assembly 36 includes a locking plate 102 supported on the housing for relative translational movement between an extended position in which the locking plate is received in an aperture of the backrest bracket to lock the backrest bracket from further pivotal movement, and a retracted position removed from the aperture to allow further pivotal movement of the seat and backrest. A locking pawl 106 is supported on a lever 104 of the tilt assembly and engages the lock plate 102 to retract and extend the plate when the lever is rotated. In addition, a clutch is interposed between the actuating lever and the locking pawl for exerting a rotating force on the locking pawl to move the locking pawl from the second position when the actuating lever is rotated. The rotating force of the clutch is smaller than the friction force that is exerted on the locking plate when the pivoting force of the spring assembly 32 is exerted on the locking plate such that the locking plate can only be retracted when the friction force is reduced to a magnitude less than the rotating force.

摘要： Condensed dimer alcohols, also known as Guerbet alcohols, are prepared using metal alkoxide as the catalyst by reacting alcohol with saturated or unsaturated aldehyde or allyl alcohol, or mixtures thereof, at 100.degree.-220.degree. C. and removing water as it is formed during the reaction. Dimer alcohols are prepared in high yields without the need for a transition metal catalyst.

The sections each having means on its upper and lower edges and its opposite vertical edges for interlocking the sections in engagement with one another. The panels each being comprised of a synthetic plastic and the panels are positioned in spaced opposed relation. Tie slots are provided in the opposed sections positioned in longitudinally spaced relation along the upper and lower edges. Synthetic plastic ties are provided with each having opposite enlarged tie ends retainingly engaged in the tie slots securing the sections in opposed spaced relation. Modular transversely extending closure panels are mounted between the opposed panels providing end closures for confining poured concrete within the form defined by the opposed panels and the end closure panels. Modular attachment means are provided between opposed faces of the opposed panels and opposite ends of the closure panels to secure the assemblage in unitary relation to define a concrete form. The reinforcing ties each are secured in permanent embedded assembly at opposite ends with the synthetic plastic opposed panels and also with the concrete when poured and hardened in the thus provided form to provide an insulated concrete wall with the synthetic plastic panels being permanently attached to the exterior of the concrete wall.
