Abstract: The instant invention features a novel binder having opposing panels, with a first panel having a binding strap gripping means at an edge of a first end of the panel and a binding strap extending from a second end of the panel such that the binding strap can be extended from the second end of the panel, around and/or through the second panel back to the first end of the gripping means of the first panel. Such arrangement allows securing of the second panel in adjustable, opposing juxtaposition to the first panel, thereby securing loose papers between the panels.

Abstract: A protective device for a chain saw comprising a generally U-shaped mounting bracket carrying pivot means pivotally supporting an elongate protecting bar spring biased towards a rest position in which the bar extends generally parallel to the chain of the chain saw in use, mounting plate means secured to one side of said mounting bracket and having a rearwardly extending portion formed with openings through which the chain bar mounting bolts of the chain saw pass for securement of said mounting plate to the body of the chain saw by means of the chain bar mounting nuts. The protecting bar has an inverted channel shaped configuration which defines a saw dust confining passage through which the saw dust passes in use. The protecting bar extends beyond the end of the chain of the chain saw to enable contact between the bar and the object to be cut without contact between the chain saw and the object.

Abstract: A compensating nail chuck includes a driving rod (12) having a yieldable force-transmitting member (34) comprised of a belleville-washer spring system which compresses in size in response to a back force on the driving rod created by driving a nail. A main housing (10) of the chuck has freedom of vertical movement on a chuck bar (26) for a distance equal to a tolerance difference to be compensated for.
