  • Patent number: 4885118
    Abstract: A process for manufacturing spherical objects which includes the steps of ejecting into a reaction medium layer a predetermined amount of liquid material which form spherical objects and allowing the spherical mass produced by the ejection to react and set while floating in the reaction medium layer. The reaction medium layer is restricted by a first blocking and protective liquid layer having a smaller specific gravity than the reaction medium layer and located above the level of ejection and a second blocking and protective layer having a greater specific gravity than that of the reaction medium and located below the level of ejection.

  • Patent number: 4265173
    Abstract: There is disclosed a numbering machine designed so that code numbers as well as check digits each consisting of a single-place digit are printed by means of a mechanical mechanism. The check digits are printed by a check digit type wheel having an arrangement of circulating digits which are calculated in correspondance with code numbers in accordance with a modulus 10 or 11 check with predetermined weights. When there is a carry from one code number digit place to the next higher digit place, it is necessary to print the digit skipped a predetermined number of the digits in the circulating digit arrangement, and as a result a drive control mechanism is provided so that when a change from one code number to the next higher code number necessitates a skipping operation, the change is detected and the check digit type wheel is rotated idly through a predetermined angle.
