Abstract: A method for operably adjusting a forming board lead blade of a paper sheet forming machine of the type having a headbox for impinging a jet of slurry from a slice opening of the headbox onto the surface of a porous wire moving continuously in a horizontal machine direction over the forming board.

Abstract: A method for calculating the required power of a toric implant by using both the measured pre-operative corneal astigmatism and the predicted surgically-induced post-operative astigmatism. The surgically-induced post-operative astigmatism is predicted using power vector analysis of the surgical technique employed by the surgeon. Such a method provides a more accurate method of calculating the required post-operative refractive power of the implant. The method can be implemented manually, but preferably is automated by implementation on a computer through appropriate software.

Abstract: A method for calculating the required cylindrical power of a toric implant by using both the measured pre-operative corneal/ocular astigmatism and the predicted surgically-induced astigmatism. The post-operative corneal/ocular astigmatism is predicted using power vector analysis of the surgical technique employed by the surgeon. Such a method provides a more accurate method of calculating the required spherocylindrical refractive power of the implant. The method can be implemented manually, but preferably is automated by implementation on a computer through appropriate software.

Abstract: A winch driven cable guidance system for coupling trailers to tow vehicles. The system comprises of trailer having a trailer hitch coupler, a tow vehicle having a coupling ball joint, and a cable whereby one end of the cable is connected by means of a cable pulley guidance system and secured to a cable drum of a winch. The winch powers the cable drum to reel in the cable and the attached trailer to assist in connecting the trailer to the towing vehicle, thus effecting a universal joint between the trailer and towing vehicle.
