Abstract: 1430244 Autoreclosing circuit-breaker system McGRAW-EDISON CO 6 March 1973 [24 March 1972] 51053/72 Heading H1N [Also in Division H2K] A reclosing circuit-breaker has contact operating means 8, 10, 40, electric closing means 50 and overcurrent responsive means 70 which is provided with a dash-pot time delay liquidfilled device 18 which has a sequence piston 230 to close vents 184, 196 to increase the delay after a number of operations determined by the positioning of an E-ring 236 in one of the notches 234 in a rod 232 extending from the piston 230. The device 18 includes a piston 210 movable against the bias of a spring 212 each time the overcurrent means 70 trips a latch 30 of the breaker as its armature 74 is attracted by an overcurrent coil 53. After breaker opening the spring 212 restores the piston 210 to pump liquid below the piston 230 to move it toward the vent closed position. The operating mechanism includes an operation counting device 20 having a plurality of positions, advancement from one position to the next occurring in response to movement of the operating means when an opening operation occurs. In the arrangement shown, the latch 30 is released by earth fault responsive means 90, or the overcurrent responsive means 70, so permitting a toggle 22, 24 to collapse causing a lever 8 to pivot under the bias of a spring 80 to open vacuum interrupter contacts 4a ... 4c of the circuit-breaker. The lever 8 moves a member 126 to release a latch 56 so enabling a lever 40 to turn clockwise under the bias of a spring 66 to straighten the toggle 22, 24 and reset the latch 30. The lever 40 also acts through a slotted link 144 to turn a bell-crank 140 which carries a pawl 150, the pawl engaging a ratchet rod 164 and advancing it a distance dependent on the setting of a screw 158. The upward movement of a rod 52 causes the closing of contacts 46 to energize a closing solenoid 50 which pulls down the rod 52 to turn the lever 40 to reclose the contacts 4a ... 4c. The link 144 moves the pawl 154 towards the end of the reclosing movement to free the ratchet rod 164 which falls slowly under the control of a dashpot 162. After a predetermined number of successive opening operations, the rod 164 opens contacts 170 to prevent any further reclosing operation. The ratchet rod 166 may close contacts 102, 104 after a predetermined adjustable number of opening operations to render operative electronic time delay means 88 for the earth fault responsive means 90.

Title: Method of and device for securing a cam on a shaft
IPC: F01L1/047
Filed: 1977-12-12
Abstract: The cam (4) is shrunk onto the control shaft (2) with a sleeve (11) in between. The seating surface (10) of the cam (4) and likewise the outer surface of the sleeve (11) are slightly tapered and the inner surface of the sleeve (11) as well as the surface of the control shaft in contact with the sleeve (11) are cylindrical. To put on the cam (4), first of all the tapered surfaces are acted upon by pressure oil so that the cam (4) is elastically expanded and can be displaced axially relative to the sleeve (11), whereupon this pressurising is removed and the cam (4) is shrunk onto the sleeve. The cylindrical surfaces between control shaft and sleeve (11) are then acted upon by pressure oil so that the cam (4) and the sleeve (11) elastically expand together and the cam can be set in its angular position relative to the control shaft, whereupon this pressurising is removed. Owing to the fact that the second pressurising takes place at the cylindrical surfaces, the pressurising of the tapered surfaces which is otherwise usual for setting the angular position and involves difficulties is avoided. <IMAGE>
