GOODS & SERVICES

Bill Changer. The first automatic device to make change for paper currency, long a vexing problem to vending-machine operators, was announced by Chicago's A.B.T. Manufacturing Corp. The table-model machine changes $1 bills by scanning the bill through six holes with photoflood lights, registering the beams on a light-sensitive surface. The machine recognizes and rejects counterfeits, foreign currency and bills of wrong denominations. It can be modified to handle $2, $5 or $10 bills. Estimated price when it goes on the market in the spring: $200.

Cinemiracle. A new wide-screen process, called Cinemiracle, that uses the largest curved screen to date, stretching from one side of the theater to the other, was demonstrated by National Theaters. Like Cinerama, it has a three-panel system of photography, but is free of the lines between panels and the side distortion of other wide-screen processes.

Crash-Proof Meter. A parking meter that swivels on a ball-joint base when hit by a car was developed by Marwin Products of Spokane.

Midget Mathematics. A calculator that adds, subtracts, multiplies and divides up to ten digits, yet weighs barely 6 Ibs. will be put on sale by Manhattan's Bohn Duplicator Corp. Price: $125.
