A hybrid transformer core assembly having a first leg having a first end and a second end, a second leg having a first end and a second end, and opposing first and second yokes coupling the first and second legs to the first and second yokes to create a closed core. The first leg and second legs are made of a plurality of packets of laminations having a high grain orientation, and the first and second yokes are made of a plurality of packets of laminations having a lower grain orientation than the material of the first and second legs. Alternating laminations of the first and second legs are staggered to alternately extend beyond adjacent laminations of the respective leg at first and second ends thereof. A portion of the laminations of the first and second legs which extend beyond adjacent laminations of the first and second legs, respectively, overlaps portions of alternating laminations of the yokes and couples with notches of alternating laminations of the yokes. Additionally, a portion of the laminations of the first and second legs overlaps portions of alternating laminations of the yokes to similarly couples the legs with the yokes.

Energy efficient hybrid core

A track bolt assembly for use in a medical application for supporting medical utility items on a track in a medical wall. The track bolt assembly comprises a bolt having a nut threaded thereon, said bolt having an opening at one end and a spring inserted in the opening. A compression pin adjacent the spring is held in the opening in the bolt by virtue of a threaded plug. The threaded plug having opening through which the pin projects to allow depression of the spring within the bolt opening. A support panel is disposed between the nut and a retaining member, said support panel designed to hold a utility item for medical purposes. The retaining member designed to interact with a rectangular shaped elongated track assembly such that when the retaining member is parallel to the track assembly the entire track bolt assembly and utility item may be mounted onto the medical wall or removed from the medical wall. The retaining member designed to be rotated within the rectangular track assembly such that when so rotated and the nut tightened onto the support panel pressure is created causing the entire bolt assembly and utility item to remain in the position to which it has been tightened.

A medical power service column for use in a hospital room for supplying electrical power, lighting and gases and also for providing a centralized support for medical equipment. The medical column comprises a lower column section having an upper end and a lower end in contact with the floor of the hospital room, a see-through section having a first end attached to the upper end of the lower column section for providing increased visibility in the hospital room and a second end extending upward toward the ceiling of the hospital room, and an upper column section attached to the second end of the see-through section for supplying room lighting for the hospital room.

This disclosure depicts a novel light fixture having a base, a support section and a cover with means for connecting electrical components on the base with electrical lighting components on the support section. The support section and cover can be assembled and disassembled from the base without the use of any tools.

Patient light with hanger and hinge arrangement for removal without tools

A medical power service column for use in a hospital room for supplying electrical power, lighting and gases and also for providing a centralized support for medical equipment. The medical column comprises a base, a wall enclosure and a top cover all having a unique flat-cornered cross-sectional shape. The flat-cornered triangular shape of the medical column allows free access to a patient in a hospital bed while supporting medical equipment in close proximity to the patient.
