Abstract: A single stacked cam bearing surface is used to actuate several cam followers in such manner that the cam bearing surface can move past one or more cam followers without actuation thereof but can be caused to stop at and actuate any desired cam follower. A stacked disc cam bearing surface of the improved cam actuator assembly of the present invention includes rotatable cam sub-­assembly discs (62,64) each having a surface well (72,74). The plurality of cam followers that bear against the bearing surface are selectively actuated by a controlled positioning of the cam sub-assembly discs (62,64) that radially aligns the wells (72,74) of the bearing surface with a selected cam follower. During a controlled rotation of the cam assemblies (62,64) through an angular position of an intermediate cam follower, the wells (72,74) of the sub-assembly discs (62,64) of the cam bearing surface are radially mis-aligned, and thereby fail to actuate the cam follower during rotation through an intermediate angular position. The wells (72,74) are aligned at a cam follower to be activated by a back and forth motion of the discs (62,64) with the wells (72,74) positioned under the followers.

Title: Protection circuit for excess voltage combined with high line current for telephone sets
Inventor: LUNDERIUS K K-E
IPC: H04M1/74
Filed: 1978-08-01
Abstract: A protection circuit for telephone sets against excess voltage combined with high line current when the line current in the voice and signal layer is controlled by electronic contacts T1, T2. A current limiting circuit T3 limits the line current when a maximum value is exceeded. If the line voltage, when the current limiting is in effect, increases too much, the power limit for the electronic contacts T1, T2 may be exceeded. A threshold- value circuit Z2 detects the voltage across the line when the current limitation is in effect and interrupts the line current, when the voltage is too high, by cutting out the electronic contacts T1, T2 and keeping them cut out until the line voltage has again dropped beneath the threshold value. <IMAGE>
