The guard portions are asymmetrical with a straight side and a tapered side, the taper preferably including a shallow bevel near the base and a sharper bevel near the tip of the guard portion. The cutting teeth of both upper and lower blades on both sides form oval shaped cutting chambers with cooperative hook configurations at the entry to the cutting chambers. The upper and lower blades are preferably identical in configuration but inverted one relative to the other in the assembly. The straight sides of the guard portions are all faced toward the power head of the trimmer to produce a hooking action as the user sweeps the trimmer during operation.

Abstract: A method for depositing chromium and iron metals on substrates is disclosed in which the chromium hardens when heated. The electrolytic plating bath preferably includes: (a) water soluble Cr(III) produced by reducing Cr(VI) with sufficient amounts of methanol or formic acid; (b) ammonium formate; (c) a sulfate catalyst, such as sodium sulfate; (d) an inorganic iron compound, such as iron sulfate; (e) sufficient amounts of boric acid to substantially saturate the bath; and (f) a sufficient amount of sulfuric acid to provide a bath pH of from about 1.0 to about 1.5. The heat-hardenable chromium deposit allows the plated substrate to be heat tempered after plating to provide a KHN of greater than about 1200. This eliminates the necessity of removing oxidation products from an unplated heated substrate. Moreover, the amount of toxic Cr(VI) present in the bath is greatly diminished, and is replaced with a Cr(III) species that is environmentally safer.

Abstract: A reloader for reloading cartridges. A reciprocating plunger carries a turret that rotates around the axis of the plunger. The turret carries a plurality of cartridges for reloading, the cartridges being symmetrically spaced around the turret axis and adapted to be indexed around the axis in a step-by-step sequence. An overhead die holder contains a plurality of dies spaced in a symmetrical pattern similar to that of the cartridges but in fixed positions. A center opening the die holder houses a rotatable bushing. The rotation of the bushing is controlled in part by a one-way clutch. An indexing shaft affixed to the turret extends from the turret axis through the bushing. The shaft has a multi-sided cross section and is slidably fitted to the bushing in a manner that prevents relative rotation. The configured cross section has an axial twist and when forced through the bushing by the reciprocating plunger, causes turning of one or the other of the shaft and turret or the bushing.
