摘要:
Genes encoding Class II EPSPS enzymes are disclosed. The genes are useful in producing transformed bacteria and plants which are tolerant to glyphosate herbicide. Class II EPSPS genes share little homology with known, Class I EPSPS genes, and do not hybridize to probes from Class I EPSPS's. The Class II EPSPS enzymes are characterized by being more kinetically efficient than Class I EPSPS's in the presence of glyphosate. Plants transformed with Class II EPSPS genes are also disclosed as well as a method for selectively controlling weeds in a planted transgenic crop field.

The mid-zone pressing tool has a base and a pressing assembly, which are pivotally connected at the rear by a transverse shaft. A pair of cantilevers extends forward from each side of an uppermost rear portion of the base. A pair of arms is connected on the distal ends by a common handle. A first coupling connects a middle portion of each arm to the pressing assembly by an axle, cam or link. A second coupling connects the proximal ends of each arm to the cantilever by an axle, cam or link. Pushing the handle down pivots the arms, engages the couplings, and transmits a concentrated downward force to the front of the pressing assembly. The cantilevers allow a range of coupling placements, including near the middle of the pressing tool. The couplings are optionally releasable.

A bone anchor locking device for receiving a bone anchor having a shank and an enlarged head, the device has a bone anchor, a dome and a conical split washer. The receiving portion has a base extending radially outward and inwardly to a wall. The dome has a center aperture sized to pass a bone anchor. The split washer has an inner conical surface sloped to slide and expand against at least a portion of the base on insertion of a bone anchor to allow a maximum diameter of a head of a bone anchor to pass and thereafter the split washer retracts overlying the maximum diameter of the head to prevent a bone anchor from backing out.

A diffusion rate limiting matrix is utilized to lingually and/or sublingually deliver thioctic acid. This limited release matrix is intended for general nutritional supplementation and/or the treatment of various physiological disorders. Due to its lingual nature, this rate limiting matrix can produce IV-equivalent plasma levels and is not meant to be swallowed.

A detachable vertical cutter for insertion into a cylinder or tube is formed as a single unitary structure. The single blade has a pair of tool attachment end portions and a cutting blade extending in a loop between the attachment ends. The cutting blade is inclined vertically relative to a longitudinal axis of a cylinder or tube into which the attachment ends can slide into. The cutting blade has a cutting edge, a portion of which when extended free of the cylinder or tube will extend a distance greater than the tube outside diameter. The cutting edge when pushed inwardly and pulled outwardly between adjacent vertebrae scrapes and cuts disc material. When retracted the cutting blade deflects into the cylinder or tube for insertion or extraction into or from the disc space.

A pneumatic drop frame trailer has lateral wheels connected to the frame by pivotal wheel support arms with airbags between the support arms and frame, a pivotal tongue member with an airbag between the tongue and the frame, a deck having an inclined ramp portion at the rear end, and a control box on the deck containing an air compressor, air storage tank, and associated valves and controls. The wheel airbags and tongue airbag can be inflated or deflated while hitched to a vehicle to raise or lower the frame evenly and horizontally relative to the ground and may also be inflated to provide stiffness or shock absorbing characteristics. When the wheel airbags are deflated, the bottom of the frame is disposed substantially horizontally and very close to the ground surface with the ramp portion substantially flush with the ground surface in a loading and unloading position.
