Abstract: A tool that facilitates aligning members with respect to each other and an object is described. The tool includes a roll of material including an upper and a lower side. The material lower side includes adhesive material that enables the tool to be affixed to the object. The material upper side includes a plurality of reference markings arranged in a cyclic pattern that is repeated along an entire length of the tool. More specifically, adjacent reference markings are a pre-determined length apart that is selected depending on a desired alignment of the members to be aligned.

Abstract: A tractor includes: (a) a one piece frame having opposite ends defined by respective members adapted for receiving ballast with the rear member including a hitch located below any mounted ballast, (b) a dual screen filtering arrangement located upstream of a radiator and an engine combustion air inlet, (c) an implement lift system including a main spring lift assist which is locked out when the implement is lowered and an auxiliary lift assist for increasing the lift assist for front-mounted implements but is mounted so as to join the main lifts assist to produce a near constant lift force during lifting the implement while producing a minimal lift force when the implement is completely lowered (d) short and long effective lengths of a steering pitman arm may be selected, for respectively minimizing steering effort or maximizing responsiveness, by respectively connecting a mounting point closest to or a mounting point farthest from a pivot axis of the arm to a drag link, (e) a steering wheel is tiltable toget

Abstract: A tractor-implement combination comprising a tractor frame supported on front and rear wheels and having left and right side plate means has a horizontal tube structure extending through the side plate means to oppositely, transversely spaced open ends. A transverse beam is slidably mounted within the tube and has opposite end portions projecting transversely outwardly of the open ends of the tube. A pair of implement supports detachably secured to said end portions and an implement is carried on the implement supports.

Abstract: A pulse-echo ultrasonic transducer probe includes a substantially centrally disposed axial bore running therethrough and a radial slot extending from the bore to the periphery of its housing. A slotted cap dimensioned to rotatably fit over the top of the housing is provided with a hollow semi-circular stem extending into the bore, the slot of the cap being aligned with the longitudinal opening of the stem. The slot of the cap and that of the transducer, when passing a surgical instrument through the bore into an opaque body, are rotatably adjusted so that they are out of registry with one another for supporting the surgical instrument and for maintaining the instrument in the center of an ultrasonic search beam. Subsequently, after the instrument has reached the desired position in the body the slots are brought into registry for providing removal of the transducer probe from around the instrument.
