Abstract: An arm rest and support for aiming. The arm rest and support consists of an upper member hingedly attached to a lower member. A pair of straps attached to the lower member wrap around the torso of the user for support. A third strap attached to the upper member is adapted to wrap around the aiming arm of the user. When not in use, the arm rest and support may be folded, allowing the user to move about. When the support is needed, the user simply raises his or her arm, causing the upper member to pivot and lock at an approximate right angle in relation to the lower member, providing the user with support for aiming resulting in greater accuracy and reduced fatigue.

Abstract: The present invention relates generally to a system for use in filtering a variety of environmental substances, and more particularly to a method and apparatus for filtering such substances as soil, sediment, and debris from such things as water runoff that may be entering storm drains or catch basins for example. The filter may be comprised of a base and a readily visible top portion. A storm sewer grate may then be inserted within the filter and placed in an opening of the inlet. Water may then be filtered, through either or both the top portion and/or through the base, before entering the inlet. The top portion functions as a visual aid, thereby allowing workers, inspectors and equipment operators to easily locate the storm sewer grate.

Abstract: A method and apparatus for a blade clamping mechanism in a woodworking plane that allows a plane iron as wide as the plane body itself to be clamped in a wedge shaped slot in the plane body. The slot begins at a point tangent to a waste ejection hole proximate a front area of the plane running diagonally towards the spine of the plane body before looping back short of the spine to return diagonally through the sole forming the mouth together with the waste hole. The loop forms the widest point of the slot, while the tangent forms the narrowest point of the slot. The rear surface of the slot serves as the ramp for the plane iron. The plane iron is clamped by a floating pin mounted in a hole drilled longitudinally through the spine, perpendicular to the ramp, and terminating at an inspection hole. The floating pin is retained between the under side of the plane iron and a conical shaped point of a screw threaded from a back of the plane body diagonally to the floating pin.

Abstract: An electronically controlled, programmable searchlight (1), particularly useful for mounting on helicopters. The searchlight (1) uses a digital electronic control circuit (30) in conjunction with rotary potentiometers (32), (34) to control movement of the searchlight (1). Adjustable trimpots (22) are employed to provide the searchlight (1) with preset positions, each preset position having an easily alterable operating envelope. The searchlight (1) may have light sources (50, 52) of varying type, which may also be controlled by the electronic control circuit (30).
