Abstract: A mechanism for producing the bead on a rubber article made by a dipping process first loosens the rubber film on the form using a pair of looseners in the form of roller brushes which contact the lower portion of each form as the forms are moving along on the form carriage. As the forms move along on the form carriage, the looseners move in the same direction as the form carriage but at a different speed, so that the roller brushes roll around the entire circumference of the lower portion of each form to thoroughly loosen the edge of the rubber film from the form. Following the loosening operation, the beads are formed by a separate bead roller mechanism which provides a bead of predetermined dimensions by rolling up the edge of the film a predetermined amount. The bead rolling operation is accomplished by a pair of roller brushes which are mounted diagonally with respect to the direction of travel of the form carriage.

Abstract: A lead guide actuating mechanism for use on armature winding machines is mounted on the same non-rotating structure that supports the wire guide forms at the end of the flyer drive shaft. An axially movable piston surrounds the flyer motor drive shaft. The piston, when actuated, contacts rollers mounted on a diametrical arranged arm mounted for rotation with the flyer drive shaft. There is no contact between the piston and the rollers until the piston is actuated. The lead guide is attached to an extension of an axially aligned pin that has a bearing surface on its end which engages the arm; it is also moved axially when the piston is actuated, and thus the lead guide is moved into position in response to the action of the piston. The lead guide and the wire guide forms are mounted on a common non-rotating structure that can be quickly removed from the flyer drive shaft.

Abstract: A simultaneous broadcast (simulcast) system transmits from a control site to two or more remote sites the same data information along with a synchronous digital signal via a synchronous digital transmission network. At the remote sites, a clock signal is derived from the digital signal for timing the broadcast of the data information on an RF carrier. The clock signal phase is periodically reset to a known phase using a predetermined pattern of data bits in the digital signal. A time delay circuit at the control site delays the synchronous digital signal such that, where RF carrier signals from the remote sites overlap, there is time coherency between the data information. The time delay circuit is constructed so as to preserve the synchronization of the digital signal.

Abstract: An apparatus for continuously transporting and dipping patterns in a process wherein patterns of a desired shape are dipped in and coated with a liquid that subsequently forms a thin membrane thereon. The apparatus includes an endless roller chain assembly that carries a number of pattern carrier assemblies through a linear dipping span. Each pattern carrier assembly includes a vertical track attached to the roller chain assembly and a carrier arm slidably connected to the track for vertical movement therein between a raised position and a lowered position. A pattern support bar is connected to the carrier arm and extends perpendicular to the dipping span of the roller chain assembly. Two or more parallel rows of patterns are suspended from the pattern support bar with their maximum width dimension extending perpendicular to the bar and with the patterns of each row being closely spaced to the patterns of the adjacent row so that at least two rows are transported simultaneously by the same carrier arm.

Abstract: A conveyor for turning conveyed parts is disclosed that operates on a lift and carry type principle. A first straight lift and carry section delivers parts to a first point. A corner or turn lift and carry section lifts these parts and turns them through a desired angle to connect the part into a second straight lift and carry section. A transmission is disclosed for interconnecting the second lift and carry section to drive the corner lift and carry section. This transmission ensures proper timing between the two. The improved lift and carry conveyor will ensure that parts are turned through an angle while remaining separated by an adequate distance.

Abstract: An apparatus for monitoring alternating currents and providing a signal representative of the current. The signals are rectified by a modified full wave rectrifier to provide a power source, a positive signal associated with the positive range of the current, and a positive signal associated with the negative range of the current. The two positive signals serve to preserve the polarity information associated with the current being monitored. The apparatus also provides for combining the negative signals to produce other signals useable by a microprocessor and an analog logic circuit.

Abstract: An automated multiple rip sawing apparatus is disclosed, wherein the boards are inspected at an inspection station to identify the lateral boundaries of the maximum usable clear area of each board. Each board is then delivered to an elongated saw feeding table which includes a transversely movable guide fence, and the board is then fed through a multiple rip saw having blades of differing separations, to thereby form a plurality of separate wood components. The transverse movement of the fence is automatically adjusted by a computer control, which includes the stored value of the boundaries of the maximum clear area of the board, and so that the board is ripped into the number and size of wood components which achieves a maximum yield from each board. Also, the saw feeding table includes a fixed support frame, and guide means for supporting the transverse movement of the fence while maintaining a high degree of accuracy in its alignment with respect to the fixed support frame.

Abstract: A contact blade for a circuit breaker configured such that the current path in the blade produces a magnetic field which affects an arc present at the contact of the blade. The configuration of the blade produces a substantially U-shaped current loop in the blade, wherein one leg of the current loop has its main component substantially parallel to, but in the direction opposite to, the main component of the current in the second leg of the loop. When an arc is formed at the contact, the current from the second leg flows through the contact and into an arc, while the current in the first leg of the loop produces a magnetic field which acts upon the arc and forces the arc off of and away from the contact.
