Abstract: A variable with block cipher using plaintext elements and masking array elements which are sometimes converted into digits in another number base. Binary bytes or digits are modified by binary rotating, shuffling of byte sequence and arithmetic/logic modification using masking arrays. For recovery of the plaintext, the ciphertext elements and masking array elements are sometimes converted again into digits and a reverse combination of rotating, shuffling and arithmetic/logic operations results in the original plaintext elements.

Abstract: A hand manipulated tool to cleanse and apply medication to a pierced body hole, such as an earlobe. The tool comprises an elongated member sized to slidably engage the pierced body hole. The tool is further characterized by first and second sections, where the first section is a cleansing section, and the second section has a medication absorbent layer to effect treatment of the pierced body hole.

Abstract: A shell for outerwear comprising an outer closely woven synthetic fabric, a relatively high-tensile-strength stratum printed on the inner face thereof and covering from 10 to 90% of the surface of the inner face, and fluorocarbon impregnation thereof.

Abstract: A process to detect the loss of a continuous spun web of plexifilament fibers exiting a forwarding apparatus depends on the manner in which the filament oscillate in a cross machine direction prior to depositing onto a collecting surface. The loss of these fibers, due to hang up in the filament forwarding device, can cause multiple position spinning machine loss due to the knock down of nearby spinning positions or wrap the sheet on forwarding rolls. The hang up in the forwarding device is referred to as a blow-up. This process detects the instant a blow-up occurs through the loss of electrostatic charge due to the absence of the oscillating swath at the sensor. When the instant charge is lost at the sensor, a signal indicates a blow-up has occurred.
