Abstract

A power-up storage rack for microcomputers is provided for use in accommodating automatic recharging of each microcomputer irrespective of its multiple uses by several different operators. The rack resembles an H-shaped channel beam. Recharging results via electrical interconnection of multi-pin (male-female) receptacles of the rack and microcomputer with a source of electrical energy as through a transformer. An indicator light can also be activated by such electrical engagement.

Claims

1. A power-up rack for a programmable microcomputer used to gather engineering data within a refinery or chemical complex for later automatic transmission to a central computer via a communication link, said microcomputer having a series of keys arranged in rows-and-columns over a top surface thereof and a first multi-pin receptacle for recharging purposes, mounted at a far end thereof comprising:

a H-shaped support means including twin up-right wall means, cross-member means connected to said wall means and end wall means forming a repository to accept and accommodate said microcomputer in a recharging electrical engagement, said repository being U-shaped throughout a substantial portion of its length, with the open side of the U facing outwardly wherein loading of said microcomputer into said rack from a loading position above said cross-member means is facilitated, said cross-member means sloping front-to-back as a function of its length, said end wall means having a second multi-pin receptacle mounted thereon and adapted to engage said first receptacle in a power-up, recharging relationship said support means including top wall means attached to said side wall means and end wall means, and a light indicator supported on said top wall means in electrical circuit with and activated by electrical engagement of said first and second receptacles, said top wall being of limited cross-wise dimension so as to extend only a slight amount into said open side of said U-shaped repository whereby when said microcomputer is loaded into said repository for recharging same, said series of keys of said microcomputer can be manipulated for testing purposes, without removal of said microcomputer from said repository.

2. Said rack of claim 1 in which said cross-member means varies in thickness across its width.

3. Method of using an H-shaped power-up rack for recharging a programmable microcomputer used to gather data within a refinery or chemical complex, for later automatic transmission to a central computer, said microcomputer also arranged to have a series of keys over a top surface thereof in rows-and-columns, and a first multi-pin receptacle mounted at a far end thereof, comprising:

(a) positioning said H-shaped rack on a substantially horizontal surface, said rack including twin up-right wall means, a cross-member connected said wall means and end wall means forming a U-shaped repository to accept and accommodate said microcomputer in a recharging electrical engagement;

(b) loading the microcomputer into said U-shaped repository of said rack by initial engagement between said cross-member of said H-shaped rack and said microcomputer from a loading position above said cross-member;

(c) causing rectilinear travel of said microcomputer front-to-back along said cross-member until electrical engagement between said first receptacle and a second receptacle attached to said rack, occurs;

(d) observing a light indicator in circuit with said first and second receptacles, the activation of which indicating the occurrence of recharging of said microcomputer and

(e) testing fieldworthiness of said microcomputer without removing same from said repository by testing functional operations thereof using input parameters provided by manipulation of said keys unobstructively keyable via the open side of the U-shaped repository of said rack.

4. Method of claim 3 in which said rectilinear travel is accompanied by a change in elevation, front-to-back, of said microcomputer as a function of length along said cross-member means of said rack.

5. Method of claim 4 with the additional step of removing said microcomputer from said rack when recharging is completed.
