To counteract the tendency of side members 12 of a frame grid electrode to become inwardly bowed, wire is wound on the members 12, starting adjacent across member 14 at maximum tension for one or successive turns along a first section, the remaining section being wound at decreased tension. All changes of tension should be gradual. Tension may be maintained at a maximum over the first third of the frame length, reduced over the next sixth and maintained at the reduced level for the remainder. Alternatively, maximum tension may be worked up to gradually over the first section of the side members 12, or a maximum initial tension, which may be used for only the first turn, may be decreased gradually over the first half of the frame length and maintained at the decreased level over the second half. A long length of side members 12, with suitably spaced cross-members 14, to be cut after winding into individual frame grid electrodes, is wound in the regions where the cuts are to be made at a lesser tension than any used in winding the electrodes themselves or with fewer turns per inch.

Abstract: 936,404. Control of several motors. WESTERN ELECTRIC CO. Inc. Jan. 20, 1960 [Jan. 30, 1959], No. 2025/60. Class 38 (3). [Also in Group XXV] In order to facilitate replenishment of bobbins in the cradle of a cable making machine, the cradle is partially rotated to predetermined positions by selection of appropriate switches in a circuit controlling the cradle driving motor. A reversible motor 110 is connected to energy source 184 through a solenoid-controlled doubleacting switch 188 in circuit with manuallyoperated switches 200, 201, 202 and limit switches 191-194 actuated by cams 196, 198, 199 on a member 28 rotatable with the cradle. Closing of either switch 201 or 202 to rotate the cradle in one direction or the other energizes the motor 110 and also closes a switch 177 to energize the solenoid of an hydraulic valve 173 that releases a catch which holds the cradle against rotation, similarly releases an hydraulic valve to disengage a multiple contact plug (not shown) in the current supply lines to motors carried by the cradle, and at the same time brings the motor 110 into driving association with the cradle. When the cradle has rotated through the desired angle, the cam 196 opens switch 191 or 192 to stop motor 110 and brake the cradle through the hydraulic valve 173. To return the cradle to operating position, the " zero " switch 200 is closed, thereby reenergizing the motor 110 and releasing the brake holding the cradle. A time delay switch in the circuit is effective, when the cradle has returned to operating position, to cause reconnection of the multiple contact plug. In the normal operating condition of the machine, mercury switches are balanced to be supported by cable binding material but rock on breakage or other failure of the material to stop the main driving motor of the machine through a circuit that includes a time delay switch.
