Abstract

In this system, information is stored temporarily in a continuous belt 1. This is by positioning individual flaps 2 over either of the adjacent belt perforations 3 or 4. The stored information can be read out by optical detectors.

Electro Optical Buffer Storage System

In this system, information is stored temporarily in a continuous belt 1. This is by positioning individual flaps 2 over either of the adjacent belt perforations 3 or 4. The stored information can be read out by optical detectors.

The belt 1 in A is constructed of an opaque durable flexible material. The flaps 2 are constructed of a material such as polypropylene which will withstand repeated flexing. Belt 1 preferably is continuous as shown in B, being arranged to travel over supporting drums 5 and 6. Information is stored in the belt in the area C'-C' of B by a mechanism shown in C.

The mechanism includes solenoid 7 arranged for downward actuation of a selector bar 8 in response to input signals received at connections 9. Selector bar 8 is normally biased upwardly by compression spring 10 as shown. Attached to selector bar 8 and movable with it are a series of staggered tab guides 11. Each consists of two side members defining a guide passage of tapered width. Fixed deflecting blades 12 are positioned to engage the tabs. This is effected as they leave the associated tab guides to deflect the tabs upwardly if selector bar 8 is in the upper position (in the absence of a signal at solenoid 7) and to deflect the tabs downwardly if selector bar 8 is in the lower position (in the presence of a signal at solenoid 7.)

By applying the signals to solenoid 7 in a properly timed serial sequence, such signals can determine the positions...
