Abstract: Colored razor blades are provided. Methods for manufacturing such blades are also provided, including methods involving subjecting a blade material to a hardening process; and, during the hardening process, oxidizing the blade material to form an oxide layer on the blade material. The method also includes quenching the blade material, after the oxidizing step, to initiate martensitic transformation of the blade material, and forming the hardened blade material into a razor blade, the oxide layer providing the razor blade with a colored surface.

Abstract: The gun storage and rapid removal mount of this invention is for securely retaining a shotgun or the like against unauthorized removal with the mount providing for rapid removal by authorized persons. It comprises a trigger guard cup and a forward lock clamp. The lock clamp engages the barrel and a magazine tube just forward of the shotgun receiver to prevent forward motion of the shotgun in the mount. The trigger guard cup prevents rearward motion. The lock clamp is both lock- and spring-retained. When its lock is released, the gun can be rotated out of the clamp against spring force. The spring also permits reinsertion of the shotgun into position against the spring force.

Abstract: A circuit for synchronizing digital signals with alternating current includes a first counter that repetitively starts a first counting sequence at a predetermined phase point in each AC line cycle and effects the sequence at a high frequency rate thereby generating a total count during each line cycle. The total count is then divided by a dividing integer to produce a count number. A second counter repetitively starts a second counting sequence at the predetermined phase point and effects the second sequence at the high frequency rate up to the count number continuously during each line cycle. A decoder responsive to the second counter produces a digital output signal at one or more predetermined points in preselected second counting sequences during each line cycle.
