An analysis of the minimum-time data of AK Her and ER Ori revelas possible sinudodal variations in their orbital periods. In the case of AK Her we suspect two additional components; one of mass 0.2 to 0.4 M with a period of 62 yr and the other of mass 0.2 to 0.6 M with a period of 207 yr. The probable third mass in ER Ori is less than 0.6 M for i ≥ to 60 ° with a long-term period of 34.78 yr.
