Abstract: A system to manufacture articles of footwear, shoe soles, shoe parts, clothing, or externally visible safety material having enhanced safety and visibility with reflective fluorescent safety particle chips, pieces, and shapes which are embedded, bonded, or mixed then are distributed in a pattern or at random throughout and integral to a bonding material which is a transparent or translucent elastomeric compound by extrusion or injection molding. The elastomers can consist of natural or synthetic rubbers, thermo plastic elastomers, vinyls (by which is meant polyvinylchloride plastics in transparent or translucent forms), plasticized vinyl (by which is meant polyvinylchloride plastics, with plastersizer, in transparent or translucent forms), butyl rubber, styrene butadiene rubber, GSR, urethane and all similar flexible transparent or translucent mediums with the reflective or fluorescent safety particle chips, pieces, and shapes distributed throughout the structure.

Abstract: A low cost credit card verifier for use in conjunction with a time-shared central processing unit (CPU) or computer in a credit card verification system in which there are a plurality of manually controlled signal generators for transmitting signals representing an account to be verified to a central processor and provision for receiving from the central processor a signal representative of the status of the account and for indicating the status of the account.

Abstract: A low cost credit card verifier unit for use in conjunction with a time-shared central processing unit (CPU) or computer in a credit card verification system. The unit includes a tone generator for generating a series of ten tones identifying the code on a crediti card whose status is to be checked. Ten adjustable digit set buttons are manually positioned in accordance with the code on the credit card. In one form of the invention, after the verifier unit is connected to the CPU via a telephone line, a roller is moved from a starting position sequentially over the positioned buttons to depress them and cause them to operate the tone generator which transmits to the CPU a series of ten tones corresponding to the code on the card. After the roller has traversed all the buttons, it is now in a second position. Upon receipt of the tones, the CPU sends back to the verifier unit a status signal which energizes indicating lamps on the unit to indicate the status of the credit card.
