Filed: 2003-12-03
Abstract: The invention provides a modular building unit comprising a shell formed from side wall lattice frameworks connected together by cross-beams at floor and ceiling height and end wall lattice frameworks secured to the ends of the resulting structure. The wall lattice frameworks are constructed at a first site where each is formed from an array of mutually parallel spaced structural uprights made from cold-formed structural steel sections, secured together by horizontal or diagonal cross-braces also made from cold-formed structural steel sections. The wall lattice frameworks are build up into the shell at a second site where each of the cross-beams, made from a cold-formed structural steel C-section, is connected to the wall lattice frameworks by being sleeved into or around lateral spur members extending from the wall lattice frameworks prior to being welded thereto.

Abstract: A fireplace having a bottom venting arrangement is disclosed. The fireplace includes a firebox having a burner and a combustion chamber. Fumes produced by burning of gas at the burner are pulled into a plenum in the upper portion o f the firebox. The plenum is in fluid communication with the combustion chambe r. The plenum is also in fluid communication with an upper end of a substantial ly vertical air passage. The lower end of the air passage is in fluid communication with a blower opening in a bottom panel of the firebox. An intake side of a blower is attached to the blower opening. The blower also includes a discharge side, which is coupled to an exhaust port on the fireplace. The blower operates when a fire is burning, and fumes containing combustion products are drawn into the upper plenum.

Abstract: Presents a liquid crystal display device that does not require a surface orientation treatment, dramatically improves the response rate of dynamic image displays and does not experience light leaks when the display is black, which means to yield a dark field of vision. The liquid crystal display device comprises polymer-stabilized blue phase liquid crystals sandwiched between a pair of clear substrates. The liquid crystal display device obtained using polymer-stabilized blue phase liquid crystals exhibits large double refraction changes when an electrical field is applied in an in-plane direction to the cell substrates. The polymer-stabilized blue phase liquid crystal comprises a low molecular weight liquid crystal that allows a blue phase to appear between cholesteric and isotropic phases and a polymer network formed in the low molecular weight liquid crystals.  Furthermore a liquid crystal display device that does not leak light when the display is black (yields a dark field of vision) can be obtained by optimizing the type and amount of a chiral dopant added to the liquid crystals.
