Abstract: An exercise apparatus for permitting multi-axis rotation of the body. The apparatus includes a seat attached to a frame and a pair of arm rests connected to the frame for motion relative to the seat and frame, and more particularly, for rotational movement relative to the seat about a first and a second axis.

Abstract: The present invention is directed to a method for forming glass articles containing internal enclosed channels.

Abstract: The present invention is directed towards a lightweight, sealant-free, thin glass envelope having a front surface and back surface laminated and integrated together, i e. specifically, a unitary envelope body having at least one discharge or ionizable gas channel. The glass envelope exhibits a weight to area ratio of .ltoreq.1.0 g/cm.sup.2. Lightweight, internally channeled light-emitting devices can be formed from these thin glass envelopes by etching electrodes to the envelope, at opposite ends of, and in communication with, the gas channel which contains a discharge or ionizable gas.

Abstract: The present invention is directed to a method and an apparatus for forming glass articles from molten glass involving differentially cooling a plunger for press forming glass articles in a cooperative forming mold. More specifically, the method involves introducing cooling fluid into an inlet cooling cavity located in the upper portion of the plunger and causing the cooling fluid to flow from the inlet cooling cavity into a cooling passage located along the periphery of the nose portion and thereafter to flow into a outlet cooling cavity located in the upper portion of the plunger and thereafter exhausting the spent cooling fluid from the plunger.
