Title: Spanning member with convoluted web and c-shaped flanges
Inventor: MCCRACKEN ROBERT G
IPC: E04C3/07
Filed: 1998-06-11
Abstract: A spanning or beam member for use in construction having a pair of opposing C-shaped flanges and a corrugated web. Laterally extended protrusions of the web strengthens the beam member by stiffening the web and increasing the load bearing forces that may be carried by the beam member without crushing. The C-shape of the flanges allows welding of the flanges to the protrusions of the web to reduce the unbraced and unstiffened size of the compression elements to allow for construction of beam members of a given strength out of thinner sheet material.

Title: Protocol interface gateway
Inventor: AUTREY KEVIN
IPC: H04L69/40
Filed: 1997-03-21
Abstract: A protocol interface gateway (84) connects a telecommunication system emulator (72) to a communications network (79). The gateway (84) receives signals from the network (79) and sends signals to the network that are formatted in a network protocol. The gateway converts signals received from the network into instructions in emulator code, and sends the instructions in emulator code to the emulator (72) for processing. The emulator executes code in blocks of application software (85) utilized in a target telecommunictions node. The gateway then receives the processed instructions in emulator code from the emulator, converts the processed instructions into signals formatted in the network protocol, and sends the signals to the communications network (79). The protocol interface gateway (84) utilizes a UNIX socket (83) that replaces Open Systems Interconnection (OSI) layers (1 and 2) of the network protocol to send and receive the signals from the network.

Title: Method and composition for treating substrates for wettability
Inventor: YAHIAOUI ALI
IPC: A61Q19/00
Filed: 1997-08-11
Abstract: Disclosed is an improved composition and method for treating substrates such as nonwoven fabrics to impart durable properties such as wettability. The composition includes a viscosity modifier that provides reduced viscosity to normally viscous treating agents allowing them to be applied at room temperature without adversely affecting the desired properties of the treated substrate. Advantageously the treating composition includes an alkyl polyglycoside having 8 to 10 carbon atoms in the alkyl chain and a surfactant such as a blend of ethoxylated hydrogenated castor oil and sorbitan monooleate. Nonwovens treated in accordance with the invention with high solids treating compositions at room temperature have a durability of at least 2 cycles in accordance with the runoff test. The treating compositions of the invention are stable and adapted to many conventional treating systems. As little as 1 part in 20 of the addition of the alkyl polyglycoside is effective. Treated substrates such as nonwovens find many applications such as components of personal care products, wipers, environmental fabrics and the like.
