Abstract: A broadhead adapter is comprised of a collar and at least one broadhead blade. The collar is adapted to receive the stud of an adjustable weight broadhead adapter bolt through an opening. The collar is adapted to securely fit between an end of an arrow shaft and the shoulder of the bolt. Each blade is attached to the collar to form an arrowhead configuration. The adjustable weight bolt is comprised of a threaded stud, a shoulder, a boss and at least one weight. The threaded stud screws into the arrow shaft to secure a broadhead adapter to it. One or more weights are attached to the bolt to incrementally increase the effective weight of the arrowhead. An arrow having an adjustable weight broadhead arrowhead may be formed by securing a broadhead adapter between the shoulder of an adjustable weight broadhead adapter bolt and the threaded opening of an arrow shaft.

Abstract: A broadhead adapter may be used to convert a field tip arrow to an arrow having a broadhead arrowhead. A broadhead adapter is comprised of a collar and at least one broadhead arrow blade. The collar is adapted to receive the stud of a field tip through an opening. The collar is adapted to securely fit between an end of an arrow shaft and the shoulder of the field tip. Each broadhead arrow blade is attached to the collar to form an arrowhead configuration. The outer perimeter of the collar should have substantially the same dimensions as the outer perimeter of the end of the arrow shaft. An arrow having a broadhead arrowhead may be formed by securing a broadhead adapter between the shoulder of a threaded arrow field tip and the threaded opening of an arrow shaft.

Abstract: An adjustment mechanism for adjusting the axial position of a terminal (16) along the end of the core element rod (12) in a motion transmitting remote control assembly (10). A coil spring (24) normally grips the knurled end of the rod (12) to prevent axial movement of the terminal member (16) relative to the rod (12). A collar (34) is rotatably disposed about the terminal member (16) and includes a slot (36) engaging a movable end (28) of the spring (24) for moving the end (28) of the spring (24) circumferentially along a recess (32) in the terminal member (16). As the collar (34) is rotated, a first end (26) of the spring (24) is held circumferentially by a hole (30) and the spring (24) unwinds as the slot (36) engages and moves the movable end (28) of the spring (24) circumferentially.

Abstract: A level measuring device for measuring the level of a liquid in a container. The device has an elongated support which extends approximately horizontally into the container and is fastened at a fastening end 6 to a wall 3 of the container while its other resting end 3 rests under initial spring pressure against the bottom 2 of the container. On the support there is fastened a carrier 12 on which a mechanical-electrical transducer is disposed and on which there is pivotally mounted a lever 13 which bears a float 14 and acts on the transducer. The support is developed as an elastic spring in the region between its fastening end 6 and the carrier 12.
