Abstract: ABSTRACT           The present invention comprises a clear separator means in combination with a framelike device to display pictures, diplomas, crewel work and other displayable items.          The clear separator means has three dimensions.  Along its length and width it is formed to fit the shelf sections of the frame or other holding means.  The separator means can be readily cut to any size to accommmodate different size frames. The separator means is fabricated from material which does not absorb water so it does not become mildewed or bleached out.          The separator means has a pressure sensitive adhesive material secured to one surface defined by its lenght and width so that when it is pressed onto a transparent means,such a a piece of glass, which is already resting on the shelf of the framelike device, it adheres to the glass and lies along the shelf position.  In this way, the separator is not readily viewable through the transparent member.  The item to be displayed lies in abutment with the separator means and is separated from the transparent member by the depth of the separator means.

Abstract: TITLE:  HIGH PRESSURE TIPLESS TUNGSTEN HALOGEN LAMP                          ABSTRACT     A high pressure, tungsten halogen lamp wherein a predetermined quantity of a gas mixture including an inert gas (e.g., argon) and halogen compound (e.g., methyliodide) constitute the lamp's combined atmosphere.  The gas mixture is flowed into the tubular member which ultimately comprises the lamp's envelope and is then cooled sufficiently to form either a pool of liquified gas or, alternatively, a frozen, solidified member.  A quantity of nitrogen gas established at a predetermined atmospheric pressure is also flowed into the tubular member while a press sealing operation is accomplished to seal the member.  When the lamp is then subjected to normal room temperature, the pool (or solidified member) becomes gasified to produce the elevated internal pressure, which may readily approach three atmospheres.

Abstract: ABSTRACT OF THE DISCLOSURE           A  resilient  stator  coil  support  bracket  is provided particularly useful  for  large hydrogen  inner-cooled turbine generators to give the end winding support assembly greater axial flexibility without substantially increasing  the radial flexibility of the assembly.  The support bracket includes an element secured to the core as well as an element secured to the brace that is radially outside  each coil  end turn with a  sheet  of  resilient material therebetween,  or there are two elements of the brace secured to the core with an intermediate element secured to the brace and the mating surfaces of all adja-cent elements are spaced by sheets of resilient material, such as of an elastomer, that flexes in shear and compres-sion modes.  The bracket is tunable in the sense that the selection of the thickness and composition of the resilient material permits adjusting the natural frequency of the assembly to avoid resonance with the excitation frequency which such gas-cooled generators are sometimes susceptihle.          Also, the resilient bracket can be easily installed in the field to replace rigid brackets on machines in which the vibration problem has appeared.
