Abstract: A vehicle orientation detecting device mounted in an automotive or other vehicle cancels an erroneous signal component of a first alternating voltage signal generated as a conductor is rotated so as to intersect a geo-magnetic field. The erroneous component is cancelled by electrically adjusting two phases and magnitudes of a second alternating voltage signal having the same period as the rotating conductor and a 90.degree. phase shifted second alternating voltage. The vehicle orientation is correctly derived from the phase difference between the normal first alternating voltage signal without the erroneous signal component and the second alternating voltage signal.

Abstract: A device for rapid loading of a muzzle-loaded firearm, our invention provides a method to carry, in ready position, all of the ingredients and implements necessary to reload a muzzle-loading firearm, both flintlock and percussion. In addition, our invention facilitates very rapid reloading due, in part, to an exclusive T-slot spring slide system which is lever activated. The device is positioned over the gun barrel, facilitated by a recess in the block; the lever is moved in either direction, thus releasing the spring slide to position itself in the open position. When this is done, the gun powder falls into the barrel and the patch and ball are then pushed through with a handily located ball starter. Priming is accomplished by using either the priming powder squeeze bottle in the case of a flintlock firearm or by removing a percussion cap from the carrying strap in the case of a percussion type firearm.

Abstract: A root-pruning container involving a series of vertical pyramid like staircase stepped surfaces essentially parallel to the sidewall of said container and displaced to the inside of said container, wherein the vertical and horizontal surfaces forming the steps between the inner pyramid like surface and the outer container sidewall are intentionally sloped behind said pyramidal surface such as to form an acute angle of intersection with the container's sidewall. Because of the acute angle of the step, the root tips of a growing plant are directed into and trapped at the toe position of each individual step resulting in termination of the root growth (root-pruning). Such a container inhibits spiral growth, promotes root branching and results in more even root distribution as well as increased root growth in the growing medium.

Abstract: A wall assembly comprised of a number of wall panels releasably coupled by clips of improved construction to spaced, vertical studs. Each wall panel has an end face and each clip has a number of tines or teeth which are forced or driven into the end face of the corresponding wall panel. The clip further has a resilient part mounted on a base part which engages the adjacent surface of a wall panel. The resilient part yields in one direction when it engages the adjacent flange of the stud as the wall panel is forced toward the stud in a horizontal direction. This permits the resilient part to pass by and thereby clear the flange of the stud, whereupon the resilient part snaps back behind the flange and thereby releasably couples the wall panel to the flange with the wall panel at the front of the flange. The resilient part is breakable from the body of the clip when the wall panel is pulled in a horizontal direction away from the stud, thereby permitting removal of the wall panel from the wall assembly.
