Abstract: A device is provided for cutting roofing caps efficiently and easily from standard asphalt or fiberglass roofing shingles. The device comprises a support base to hold a shingle, the support base being hinged to a top plate having cutting blades affixed thereto. The support base has cut-outs corresponding with and acting cooperatively with the configuration of the cutting blades. Standard shingles can be cut to desired patterns. Preferably two interior, wedge-shaped cut-outs and two exterior, beveled cut-outs are employed in the support plate, and cutting blades are arranged in the top plate so as to penetrate the shingle along the bevels and the sides of the wedges and thereby cut the shingle in the desired pattern and permit unwanted shingle material to fall away and be discarded, producing three precision-cut roofing caps from each shingle.

Abstract: A remote-reading compass in which a compass assembly is buoyantly supported within a housing to accommodate a large range of tilt. Buoyancy is provided by a float surrounding the compass assembly and a liquid within the housing chamber. A pivot pin extends from either side of the float along a first normally horizontal axis to permit rotation of the float and compass assembly about the axis. The ends of the pivot pin ride in a circumferentially extending track which is disposed on the interior of the housing. The track permits rotation of the compass assembly and float about a second normally horizontal axis orthogonal to the first axis of the pivot pin. In this manner, the compass assembly is permitted to remain in a normally horizontal orientation during movement of the compass housing without need of gimbals, and rotation about a normally vertical axis is prevented. In addition, the track and the pivot pin together maintain a desired spacing between the float and the interior of the housing.

When it is desired to use the belt as a toy, a belt end is detached from the buckle, the belt is removed from the user's waist, and the vehicle is actuated to move along the belt. The buckle further includes additional retainers for retaining the belt in various configurations to enhance the use of the belt as a track for the vehicle.

Abstract: The apparatus includes an endless rope trained over two distally mounted sheaves which define paths spanning either side of said sheaves and means for the continuous application of herbicide to the endless rope. The means for applying herbicide to the rope includes an immersion basin in which portions of the rope are continually pulled through a bath of liquid herbicide. The endless rope is fabricated of synthetic polymeric material, such as nylon, and is made by applying heat to the two free ends until the polymeric material melts and the two free ends are then welded together. Since the endless rope is under some tension, as it traverses the path defined at each end by the sheaves, a second endless rope is tack-welded to the edge of the drive rope at spaced intervals of 1 to 3 inches, again by application of heat to the outer surfaces of the two ropes at the point of contact until the polymeric material is melted to the extent required for welding the two ropes together.

Abstract: A method is disclosed which selects for different types of mutants expressed in cereal seed. The method allows rapid qualitative or quantitative screening of the aleurone GA.sub.3 -induced expression of alpha-amylase activity in half-seeds (without embryo). Half-seeds of the M.sub.2 population of mutagenized cereal seeds are incubated under selection pressures that normally inhibit the expression of alpha-amylase activity. These selection agents include metabolic inhibitors which may function at the level of transcription, translation, or protein secretion.These selection agents include antimetabolites such as amino acid analogs (e.g., S-2-aminoethylcysteine, p-flourophenylalaine, canavanine, etc.), antibiotics (e.g. Actinomycin D, cycloheximide, erythromycin, kanamycin, streptomycin, or tunicamycin), biocides, herbicides, water or salt stress. Such selection pressures may be applied to the half-seed method in the presence of absence of GA.sub.3, ABA, and at various incubation temperatures.
