Abstract: AIR WARMING DEVICE TO FACILITATE BREATHING         Abstract of the Disclosure An air warming device to facilitate breathing com-prising an air warming chamber of flexible thin wall constric-tion and preferably including a plurality of cells adjacent to each other having a relatively broad surface area and rela-tively shallow depth for placing against the chest region o. the person using the device to warm air which is taken into the chambers of the cells.  Each cell has a relatively large opening at the bottom end and a relatively smaller opening at the upper end.  A first manifold member is secured to the bottom of the plurality of cells, having an open wall adjacent to the bottom openings of the cells, and a single relatively small opening in the opposite wall of the manifold for air from the outside to enter this first manifold member whereupon the air is distributed to the bottom openings of each of the cells making up the warming chamber.  Body heat from the user warms the air in the warming chamber.  A second manifold member is secured to the upper end of the warming chamber enclosing the top openings of each of the cells.  The second manifold member also includes an open wall adjacent to the top openings of the plurality of cells and a single small opening in the opposite wall of this second manifold member.  A breathing tube extends from this single small opening in the second manifold member to a breathing mask placed over the user's nose.  When the user inhales,warmed air is drawn from the warm-ing chamber to the breathing mask for the user to breath warmed air.  The breathing mask includes exhaust valve means to enable exhaled air to escape to the outside when the user exhales.  A section of insulating material is placed over the outwardly facing wall of the warming chamber to aid in retain-ing the warmth of the air therein as it is warmed by the body heat of the user.  This device is particularly beneficial for

Abstract: ABSTRACT OF THE DISCLOSURE        An X-ray tube has a wide area cold cathode with a graphite felt surface which faces and is spaced from a wide area anode of high atomic number material.  A grid is interposed between the two and the anode, grid and cathode are enclosed in an envelope which is filled with gas at a low pressure.  The graphite surface of the cath-ode is connected to a relatively high negative potential so that electrons are emitted from the entire surface area and impinge upon the anode, after triggering by the grid.  The distribution of the energy of photons emitted from the anode is relatively constant during the ignition period of the tube.  An extremely wide area X-ray source is then defined having constant bremstrahlung content which enables good gray scale measurements when employing the X-ray source.  A pinhole collimator disposed exter-nally of the tube ensures collimation of the output X-ray field.  A polarized electron beam is used as a collimator in place of the pinhole collimator, in a preferred embod-iment, to produce a collimated, wide area X-ray flux. The cathode, grid and anode structure can have any de-sired size or shape.  The X-ray source can be flat and sized to illuminate a chest X-ray film or can be arcuate to at least partly wrap around the subject to be exposed to the X-rays. Arcuate X-ray sources can be linked end to end and scanned sequentially to define an X-ray source for use in Computer Axial Tomography (CAT) scan type ap-plications.  The same computer algorithm used for conven-tional CAT scan analysis can be used.
