Abstract: Boot Seal Abstract An elastomeric seal apparatus having an inner annular terminating portion which is attachable to a first member, an outer annular terminating portion which is attachable to a second member, and an annular convoluted flexible portion which is disposed between the inner and outer terminating portions and has an inner and an outer margin which are respectively joined thereto.  The thickness of the convoluted flexible portion decreases from the relatively thicker inner margin to the relatively thinner outer margin in proportion to a radial distance extending from the inner margin to the flexible portion.  A concentrically inner convolution and a concentrically outer convolution constitute the flexible portion and have a relatively small and a relatively large radius of curvature.  When the inner and outer terminating portions are relatively reciprocated with the first and second members about a longitudinal seal axis , the tapered, convoluted structure of seal apparatus exhibits extended life as a result of substantially equalizing the maximum uniform strains induced therein.

Abstract: ABSTRACT     A window assembly adapted to be mounted in an opening between inside and outside faces of a wall has a fixed annular frame formed of a metallic profile which will extend around the opening when the window assembly is mounted in the opening, and having a flange which will then be juxtaposed with the outside face around the opening.  An annular seal will be compressed between the flange and the outside face and a sash frame fits snugly within the fixed frame.  Thus the fixed frame will be pressed from outside into the opening to compress the seal, and will then be secured in place.  The fixed frame is of L-section and has a relatively long box-beam leg lying within the opening and a relatively short leg constituting the flange.  This flange is formed with a groove open inwardly toward the outside surface and receiving the seal which itself is flexible and thermally insulating.

Abstract: ABSTRACT OF THE DISCLOSURE    A photoflash unit comprising a plurality of 2n flashlamps attached to a printed circuit board and disposed in a linear array with the longitudinal axes of respective lamps aligned in parallel. Circuit patterns on the circuit board include a plurality of n selective terminal means, each associated with a respective pair of the lamps and connected to one lead-in wire of each of the lamps of the associated pair, and a common terminal associated with all of the 2n lamps but directly connected to the other lead-in wire of one lamp of each pair. Groups of circuit pattern extensions are located behind alternate lamps of the array, the first group comprising two spaced apart segments and the remaining groups each comprising three spaced apart segments. Each group of segments is covered with a mass of radiation sensitive switch material to thereby provide respective solid state switches between bridged segment gaps which are activated upon receiving radiant energy emitted by an adjacent lamp. The circuit pattern arrangement provides a pair of respective normally open switches coupled between the common terminal and a lead-in wire of the other lamp of each pair of lamps, except for the least, one switch positioned for activation by the prior lamp in sequence and the other switch positioned for activation by the next lamp in sequence. In this manner, the second lamp of the first n-1 pairs of lamps can be switched by either of two parallel radiation switches, thereby providing redundant switching in the event that the first lamp in any of the first n-1 pairs of lamps is defective.

Abstract: BUILDING PANEL Abstract of the Disclosure A building panel having inner and outer faces outlined by opposite ends and an upper and lower edges with opposite ends of the panel adapted to closely face the ends of adjacent panels in the same course. The outer face of the panel includes a lower portion of substantially greater surface area adapted for exposure and an upper portion of relatively smaller surface area adapted to underlie a lower portion of the back face of one or more panels laid up in the next higher course.  At least one of the opposite ends of the panel is formed with a spacer projection adjacent the smaller upper portion thereof extending outwardly to provide an expansion space between a lower portion of said one end and an end of an adjacent panel positioned in the same course or row.  The pro-vision of a spacer eliminates the need for an installer to attempt to provide for adequate expansion space between panel ends when installing the panels and automatically insures that an expansion space of the desired width is present and not forgotten during installation of the panels.
