In the 1960s the development of the Microdensitometer attracted the attention of an American company, Technical Operations Inc of Burlington Massachusetts. Technical Operations Inc carried out research in advanced optical and associated techniques for government customers in atomic energy, space and defence. Following the purchase of a number of Microdensitometers, Technical Operations Inc developed an attachment which would extend the capability of the Microdensitometer and enable it to carry out a process later named Isodensitometry. The isodensitometer attachment resulted in growing contact and technical cooperation between Joyce-Loebl and the Technical Operations company.

In 1967 Joyce-Loebl sold Technical Operations Inc a quarter of their equity. In 1969 Joyce-Loebl sold the rest of their shares to Technical Operations, although Herbert Loebl remained Chairman of the Board and Managing Director for a further 18 months. In 1972 the name of Joyce-Loebl & Company Ltd was changed to Technical Operations Ltd. In 1974 Herbert Loebl retired from the Technical Operations Board.
