IPC: H01R43/16
Filed: 1994-11-21
Abstract: A female electrical terminal element has means at one end for crimping a wire lead thereto and a second end in the form of a socket for receiving a male contact pin.  The socket includes a cantilevered contact floor which is unitary with the socket and is formed by folding the cantilevered contact floor about a bight while maintaining support at the bight.  A spring biased contact is disposed within the socket in opposed relation to the cantilevered contact floor for urging the male contact blade into abutment with the cantilevered contact floor.  A method for forming a female electrical terminal component from a unitary blank utilizes folding a pair of side flanges to extend substantially normal with respect to a base portion to form a channel.  A cantilevered contact floor is then folded about a bight, while in alignment with the channel and supported at the bight, to overlie the base portion.  The side flanges are then bent so that free ends thereof overlie the contact portion in spaced relation with respect thereto to form the socket.

Filed: 1994-12-14
Abstract: A transmissive, backlit color twisted-nematic or super-twisted-nematic liquid crystal display employing a front fiber-optic faceplate as a front retaining element of a liquid crystal cell that increases viewing angle between the display and a viewer while minimizing or eliminating undesirable variations in luminance, contrast ratio and chromaticity is described. This novel configuration effectively decouples the liquid crystal cell and other optical elements behind the front fiber optic faceplate from the angular orientation of the viewer with respect to the display. The liquid crystal display described in this invention further provides a high quality color display, without viewing parallax, using a color selection filter mosaic outside of the liquid crystal cell. The display also increases luminous efficiency and improves color saturation by concentrating the transmission of available backlight illumination through the use of a rear fiber-optic faceplate and a second rear-mounted mosaic of color interference filters.

Title: Curb ramp
Inventor: HERMANSON SHAWN D
IPC: E01C11/22
Filed: 1995-01-18
Abstract: In recent years, urban areas have replaced the typical square sided curb with a sloped rounded curb. These rounded curbs eliminate the need to put in driveways for people with front entry garages. The rounded curbs make it possible to drive a vehicle up and over the sidewalk, but there can still be a large bump. This causes discomfort for the passengers and is a hazard for the vehicle. At times, the vehicle bottoms out on the sidewalk or street causing immediate damage. This invention is a relatively narrow filler ramp made from recycled rubber. It allows for quiet smooth passage over the sidewalk curb. Having a drainage port molded into the product, it does nor effect the regular flow of water.

Title: System and method of decreasing nox emissions from a fluidized bed reactor
Inventor: ABDULALLY IQBAL FAZALEABBAS
IPC: B01D53/54
Filed: 1995-06-23
Abstract: A system and method are disclosed for lowering NOx levels in flue gases of a fluidized bed reactor using selective non-catalytic reduction. A reactor is connected to a separator by a duct, and a reactant is introduced into the duct for decreasing NOx levels in the flue gases passing from the reactor, through the duct, and into the separator. The reactant, such as ammonia or urea, is selectively injected into a gaseous-rich region of the duct, near an upper, inner portion of the duct, so that a high degree of mixing of the reactant with flue gases is achieved while maintaining a low degree of mixing of the reactant with the particulate materials. The point of injection of the reactant into the duct is also at a location nearer to the reactor than to the separator to provide for increased residence time. In this manner, the reactant is used efficiently while obtaining the desired lowering of NOx levels in the flue gases.

Patent CA-2170528-A1 (CA)
Inventor: SCHEMBRI CAROL T
IPC: G01N1/28
Filed: 1994-09-01
Abstract: The present invention provides centrifu-gal rotor (52) for delivering a liquid, typically a biological sample such as diluted plasma, to an unvented chamber in the rotor (52) through an unmodified inlet channel (60). The unvented chamber is typically a cuvette (62) compris-ing reagents necessary for analysis of a bio-logical sample. The unmodified inlet channels (60) are sized such that, as the rotor (52) spins, gas escapes from the chamber through the in-let channel (60) as the liquid enters the cham-ber through the inlet channel (60). The pri-mary feature which allows the air to escape from the unvented chamber (62) is that the cross-sectional area of the inlet is greater than the cross-sectional area of the liquid flowing through it.
