Inventor: ARROYO CANDIDO J
IPC: B29C48/00
Filed: 1992-02-25
Abstract: CABLE HAVING WATERBLOCKING PROVISIONS BETWEEN LAYERS OF RELATIVELY RIGID AND SUPPLE MATERIALS Abstract A communications cable (20) includes a core (22) comprising a plurality of transmission media having a relatively supple layer (26) of a plastic material wrapped thereabout. Disposed about the layer of plastic material and in engagement therewith is a relatively rigid inner plastic jacket (28). Disposed about the inner jacket are additional components of a sheath system such as metallic shields and one or more additional plastic jackets. Interposed between the relatively supple layer of plastic material and the jacket is a waterblocking system which comprises two elongated strand materials (41,44) such as yarns. The two elongated strand materials are wrapped helically about the layer of plastic material in opposite helical directions. The elongated strand materials are effective to intercept water which may travel along the cable between the relatively supple layer of plastic material and the jacket which is contiguous thereto.

IPC: B09C1/00
Filed: 1992-03-03
Abstract: A system for treating groundwater contaminated with acidity or other contaminants is disclosed. The system involves excavating a trench into the aquifer in the path of the contaminant plume, and placing a body of active material in the trench. The active material depends on the particular contaminant: organic carbon may be used when the contaminant is ferrous sulphate, or hexavalent uranium oxide, or dissolved nitrate; pyrite or elementaliron may be used when the contaminant is eg chromium oxide. The active material causes the contaminant to transform or break down by chemical reaction into harmless precipitates and substances.

Patent CA-2063114-A1 (CA)
Inventor: MCGARRAH ROBERT G
IPC: E03C1/10
Filed: 1992-03-16
Abstract: A backflow valve for use in a post-mix carbonator system for preventing the backflow of carbonated fluid, thereby preventing the contamination of the fresh water supply, and indicating when such a backflow condition has occurred.  In a first embodiment the valve comprises a check seat body which houses an elastomeric valve member, and a sight glass body for viewing the position of the elastomeric valve member.  The valve also comprises top and base connectors for connecting the valve to the fluid carrying line and a shut-off/flush valve for controlling the flow of fluid through the device.  The elastomeric valve member allows the flow of fluid from the supply to the outlet when the fluid pressure at the supply exceeds the pressure at the outlet and prevents the reverse flow of fluid when the pressure at the outlet exceeds the pressure at the supply. As the pressure downstream increases, the elastomeric valve member is forced in the upstream direction over a plurality of steps in the check seat body.  As the elastomeric valve member passes over each step, it engages the step and is thereby prevented from moving downstream.  The position of the elastomeric valve member may be observed through a sight glass body which has a line marking the normal position of the elastomeric valve member.  In a second embodiment the elastomeric valve member is slidably disposed within a retaining chamber that is positioned between the upstream and downstream portions of the valve.  Under normal operating conditions, the elastomeric valve member is in a normal first position allowing fluid flow therethrough; however, in a backflow condition, the elastomeric valve member slides into a second position within the retaining chamber and fluid flow is restricted.  In addition, once the elastomeric valve member is in the second position, it is secured in place and a backflow condition is thereby indicated.

Abstract: Abstract A recipient  for  stackable  containers  is designed in such a way that simple manufacture and suitable  storage  of  the  stackable  containers  is possible with increased stability. To this end the longitudinal strips (10) for the construction of a recipient tube (1) are divided and the two parts are joined  together  into  a  continuous  unit  by  an overlapping catch connector. The longitudinal strips (10)  are  introduced  into  recessed  cut-outs  in intermediate plates (3") and an upper and lower end plate 13; 3') which are of sufficient rigidity. The attachment to the intermediate plates  (3")  and to the end plates (3; 3') is simplified by the divided form of the longitudinal strips (10). In the region of the upper end plate  (3) are fitted elastic or movable components so that the stackable containers must always be inserted into the recipient tube (1) by their bottoms first,  the diameter of which is smaller than that of the aperture end.

Title: Process for producing gypsum flake from flue gas desulfurization
Inventor: WELLIVER WILLIAM R
IPC: C04B11/26
Filed: 1992-09-18
Abstract: This invention relates to an improved process for producing gypsum calcium sulfate dihydrate flakes from powdered gypsum calcium sulfate dihydrate obtained from the desulfurization of flue gas by the wet limestone process. The flakes have sufficient size and strength such that the gypsum calcium sulfate dihydrate can be handled and processed in conventional equipment commonly used by wallboard manufacturers and others in the construction industry. The intermediate calcium sulfate dihydrate from the desulfurization process is dewatered to about 5 to 12% by weight and then compressed into a thin sheet under a compaction or compression load of 4 tons force to 15 tons force per linear inch of sheet width. A linear speed of from 0.5 to 2.5 feet per second is maintained during compaction providing a compaction residence time of from about 0.2 to 1.2 seconds. An elevated temperature is maintained during the compaction process to enhance the reformation of the crystal size and shape of the gypsum calcium sulfate dihydrate. The combination of pressure and temperature on the moist gypsum calcium sulfate dihydrate alters the physical characteristics of the gypsum calcium sulfate dihydrate, thereby resulting a sheet which breaks into hard flakes on exit from the compaction zone.

IPC: C12Q1/527
Filed: 1992-04-03
Abstract: A heparinase derived from Flavobacterium heparinum which meets all requirements for a clinical reagent that can eliminate heparin interference of normal blood function has been developed. The heparinase, derived from Flavobacterium heparinum, is free of a component that inhibits coagulation wherein the anticoagulant component does not bind, and the heparinase does bind, to a polysulfated resin having a pH of 7.0 and a conductivity between 3 and 12 mmhos. It is stable under normal manufacturing, shipping and clinical storage conditions for at least one year. The heparinase in useful in vitro to eliminate the interference in hematological assays due to the presence of heparin. The heparinase is also useful for the in vivo neutralization of heparin during surgical procedures. Advantages of this enzyme are that it achieves neutralization faster and more completely than previously available enzymes and is stable for long periods of time.

Title: Network traffic management
Inventor: PRATT CHRISTOPHER D
IPC: H04L1/18
Filed: 1991-10-09
Abstract: A network traffic management system and method for a relay-based communications network such as Frame Mode Bearer Service (FMBS) in which terminals (A and B) are linked by nodes (N) through which calls are routed, consists of setting a Recovery Needed flag at a node on detection of incorrect transmission of a frame or congestion at a node which discards the frame. The destination terminal (B) is notified by transmitting a null frame giving rise to a negative acknowledgement (NAK) received at the source terminal (A). The discarded frame is retransmitted with a Recovery flag set. At the node (N) the Recovery nag is detected and the frame is transmitted toward the destination terminal in the normal way. If the Recovery flag is not set and the Recovery Needed flag is set the frame is discarded. In this way, the rest of the network is not burdened with the transmission of frames that will be discarded by the destination terminal in any event until the discarded frame is correctly received. Furthermore, discarding frames that will not ultimately be transmitted successfully allows more accurate monitoring of successfully completed frame transmissions in order that more accurate billing of the customer can be employed.
