IPC: E02B3/00
Filed: 1995-05-10
Granted: 2005-07-26
Abstract: A liquid barrier system includes a structure forming a below ground level float-receiving chamber. An inlet passageway for ground water or other liquid directs the liquid into the bottom of said chamber to fill the chamber when it is desired that a barrier wall-forming part of the barrier system is to rise above ground level. Where the barrier system is a flood water barrier, the chamber bottom connects with a sewer system so that the chamber does not fill unless flood risk conditions exist, as when sewer back-up occurs. A float structure with which the barrier wall is associated is vertically movable in the chamber from a bottommost position therein when there is no liquid build up therein to an uppermost position when said liquid rises therein where the barrier wall is substantially above ground level. Seals are provided which prevent the liquid from gaining access to said one side of the barrier wall.      The seal preferably include surfaces on the housing structure and surfaces on the float structure which surfaces engage and are pressed into sealing relation by the buoyancy forces on the float structure when it reaches its uppermost position.

Abstract: Oxygen sensor deterioration is detected by initially counting the number of fuel units required to change the output voltage of a nondeteriorated sensor between first and second voltages, and subsequently counting the number of fuel units required to change the output voltage of the sensor between the first and second voltages, as the sensor ages, until a subsequent count exceeds the initial count by a given amount. The method detects when the air/fuel ratio desired for normal engine operation drifts outside acceptable tolerance. The method detects and stores a first difference between air/fuel ratios, corresponding to first and second sensor output voltages, and then subsequently detects a second difference between air/fuel ratios, corresponding respectively to the first and second sensor output voltages. When the second difference exceeds the first difference by a given amount, deterioration is indicated.

Granted: 2007-04-17
Abstract: The invention is a method of identifying the presence of, and monitoring, a disease state in a mammal which is associated with degradation of connective tissue in the mammal. The method detects and determines whether diagnostically or prognostically significant levels of YKL-40 protein and/or YKL-40 peptide are present in a biological sample. The method can be used, for example, to identify the presence of inflammatory or degenerative joint desease or degeneration of connective tissue in organs. Serum YKL-4O levels as detected and quantified by the inventive method are also suggestive of the prognosis for the length of survival in breast cancer patients following recurrence and/or metastasis of weir cancers. The figure shows the elution position of substantially pure serum YKL-40 on a gel filtration column.

Abstract: An interbody fusion device includes a tapered body defining a hollow interior for receiving bone graft or bone substitute material. The body defines exterior threads which are interrupted over portions of the outer surface of the device. The fusion device defines truncated side walls so that on end view the body takes on a cylindrical form. The side walls are provided with vascularization openings, and the body wall device includes opposite bone ingrowth slots extending through the interrupted thread portion of the body. An implant driver is provided which engages the truncated side walls to complete the cylindrical form of the implant at the root diameter of the interrupted threads. The driver facilitates threaded insertion of the implant to the intra-discal space between adjacent vertebrae. The implant is tapered at a predetermined angle generally corresponding to a desired lordotic angle of the spine. The implant is inserted to a determinant depth into the intra-discal space to restore the normal lordosis of the particular vertebral level. The lordotic angle is restored not only by way of the taper of the implant itself, but also as a function of the depth of insertion of the implant into the space. The implant is readily adapted for insertion from either an anterior or a posterior approach. In the anterior approach, the implant is screw threaded into position, while in the posterior approach the implant operates as a cam to spread the vertebral bodies apart to an appropriate lordotic angle.

Granted: 2000-05-02
Abstract: An injection stretch blow molding apparatus and method wherein while the preforms (1) are amply cooled the injection molding cyle time is shortened and furthermore a small number of blow cavities are used and the operation rate of these blow cavities is increased. In an injection molding section (14), N (N  2) preforms (1) are injection molded and then released from the injection cavity mold (42) at a relatively high mold-release temperature. While the preforms (1) are cooled by the injection section core mold (50), they are carried to a preform ejecting section (16). After the preforms cool to a temperature at which they can be ejected, the preforms (1) are ejected from the injection core mold (50). In a transfer station (200), n (1  n < N) of the simultaneously molded N preforms (1) at a time are transferred to a blow molding station (300) in (N/n) transfer operations.  In the blow molding station (300), each preform (1) is carried by a carrier member (330) through a heating section (306) and a standby section (308) into a blow molding section (310). In the blow molding section (310), n bottles (6) are simultaneously blow molded from n preforms (1).

Abstract: A tundish (10) and, more specifically, an impact pad (20) is formed with a bottom impact surface (24) and includes an outer side wall (28) extending upwardly therefrom which fully encloses an interior space or cavity (29) having an upper opening (30) into which molten metal (34) is directed from a ladle shroud (18), The outer side wall (28) of the pad (20) includes an inner surface (28a, 28b) extending from the bottom impact surface (24) to the opening of the pad (20). The inner side wall surface includes an annular portion (28b) which extends inwardly and upwardly toward the opening (30) of the pad (20). In the preferred embodiment, the inner side wall surface (28a, 28b) curves continuously from the bottom impact surface (24) to a vertical wall (30) defining the opening of the pad (20). The pad (20) redirects the pouring stream (34) back into itself causing the counter current flows (34, 36) to slow each other down thereby minimizing turbulence and inhibiting high velocity flow within the tundish (10). The upward flow (36) is further advantageously directed away from the incoming pouring stream toward the surface of the bath (16).

Title: Means for and methods of preparing paper coating
Inventor: PARDIKES DENNIS G
IPC: C07C57/13
Filed: 1996-05-06
Granted: 2006-02-28
Abstract: The invention is a paper coating system which introduces ASA particles having sizes in the sub-micron region into an emulsifier without shearing the emulsifier. The system has a continuous output -- as distinguished from a batch system. The system comprises a variable speed low pressure starch metering pump, a variable speed high pressure ASA metering pump, a high pressure atomizing nozzle assembly, and a manifold which brings the starch and the atomized ASA flow together. The high nozzle pressure breaks up or atomizes the ASA into minute sub-micron particles that are evenly distributed throughout the starch to form a nearly perfect oil in water emulsion. By controlling the nozzle pressure, the proper particle size can be produced quite easily. An optical monitoring device that uses a coherent (laser) light source continuously measures and validates the quality of the ASA emulsion.

Abstract: A signal transmission tube assembly includes a signal transmission tube (12), such as a coil of shock tube on a spool (10), having opposite terminal ends (14, 16) and containing a reactive material. The open terminal ends (14, 16) of the shock tube provide the sole exits for the signal generated therein and sole entry points for contaminents. Sealing means (18a, 18b) seal both terminal ends (14, 16) of the signal transmission tube (12) against escape from the assembly of the signal engendered by initiated reaction of the reactive material, and protects the interior of the signal transmission tube (12) from contamination. The sealing means (18a, 18b) may be a releasable sealing means (18a, 18b) which can be actuated to release the transmission tube (12) from it, thereby facilitating re-use of the sealing means (18a, 18b). Further, the sealing means (18a, 18b) may comprise a surge chamber (25) to relieve pressure engendered by reaction of the reactive material and thereby militate against rupture of the signal transmission tube (12) and consequent release from the assembly of a signal. A signal-rupturable diaphragm (44) may be interposed between the signal transmission tube (12) and the surge chamber (25).
