A fin alternating and delivering apparatus is provided for orientating and delivering fins emanating from a fin mill to a fin trayer for assembly into a heat exchanger. The fin alternating and delivering apparatus includes an entrance chute for receiving fins emanating from the fin mill in a horizontal position. The fin alternating and delivering apparatus also includes a sensor disposed adjacent the entrance chute to sense the fins entering the entrance chute. The fin alternating and delivering...

An alternating breast nursing system for facilitating nursing from each breast alternately between feedings during breastfeeding of an infant. The alternating breast nursing system includes a pair of fasteners, each coupled to an associated cup of a nursing bra and a indicator couplable alternately to a selectable one of the fasteners to indicate which breast should be used next for feeding.

A magnetic ore purification system for enriching magnetic ore concentration in a feed material. The system includes an elutriator, an alternating current magnet, and an ultrasonic separator. The elutriator has a feed port for introducing the feed material into the elutriator and an enriched material port for collecting an enriched material having a magnetic ore concentration that is greater than the feed material. The alternating current magnet generates a uniform low strength magnetic field wit...

A rotor for an alternating current generator of a type that has two pole segments provided with interleaved pole teeth and a core disposed between the segments that carries a field coil. The shaft of the rotor carries a slip ring assembly having two metallic slip rings. A ball bearing is disposed between one of the pole segments and the slip ring assembly. A portion of the shaft that is located inside of the inner race of the ball bearing has a pair of slots and wires for connecting the field co...

Disclosed is a TIG welding apparatus having an electrode connected to a power supply which applies to the electrode a predetermined voltage of either a negative or positive polarity. Control logic controls the electrode polarity to create a welding phase with the electrode at a negative polarity, a cleaning phase with the electrode at a positive polarity, and a momentary power off phase as the polarity of the electrode is switched. An arc initiation unit reestablishes the arc after start up when...

An inflatable support pad wherein a first group of inflatable cells are in flow communication with each other, a second group of inflatable cells are in flow communication with each other, and the cells of the first group of cells are interleaved with the cells of the second group of cells whereby the cells are alternatively inflatable and alternately exhaustible. Seal seam portions or walls which separate adjacent cells have serpentine shapes and are disposed relative to each other to define al...

In the alternating current generator for vehicle, an armature coil comprises a Y-connected first three-phase armature coil and a delta-connected second three-phase armature coil whose phase windings are inserted into same slots respectively. Each of the three-phase armature windings is provided with rectifying means for converting respective a.c. output into a direct current. The direct currents are summed to provide an output of the generator. It is effective to use a plurality of rotary magnet...

An alternating-resilience engine mount consists of a supporting component and a supported component, both of which move back and forth across an axis. The supported component is supported by the supporting component through the intermediary of two series-connected resilient rubber components. The motion of the second resilient component can be impeded when necessary by a so-called "auxiliary device ". According to the invention, the two resilient components are interconnected and separated by a ...

A polyphase alternating current motor has in addition to a main winding that can be connected to a voltage source, a auxiliary winding arranged in the stator, such that at least one condenser is connected to both windings per phase. A decrease in condenser size while at the same time improving the degree of effectiveness is possible by virtue of the fact that the main and auxiliary windings are arranged in such a way as to yield an increase and phase leading of the voltage adjacent to the conden...

A modified clothes hanger configured to suspend belts from a clothing rod. The device has a hook on its upper extreme, and a transverse beam on its lower extreme. A series of alternating prongs extend outward and upward from the transverse beam. The hook is placed over the clothing rod to install the device in a closet. The belt buckle of each belt to be hung is placed over one of the alternating prongs. The prongs are positioned and oriented so that the resulting weight placed on the hanger is ...
