Abstract: A semi-batch process is provided for making a diene rubber latex. The process involves (a) providing an amount of an initial liquid batch composition (containing water, emulsifier and diene monomer), sufficient to occupy from 50 to 80 volume percent of a pressure reaction vessel based on the total volume of the vessel, (b) feeding to the vessel a liquid feed composition containing diene monomer and initiator, (c) providing cooling to the vessel to cool the liquid and vapor therein, and (d) reacting the diene monomer to a final diene monomer conversion level of at least 80 mol percent based on the total moles of diene monomer used in the reaction, and the final liquid volume level in the vessel being at least 80 volume percent based on the total volume of the vessel. The process allows for a high initial reaction rate which peaks early in the process when efficient vapor phase cooling is maximized, and maintains a low latex viscosity throughout the process thereby providing efficient liquid phase cooling during latex in the process. The present process allows for higher levels of production over batch utilizing the same vessel volume. A rubber latex is also provided having a narrow particle size distribution, and a vinyl aromatic-diene rubber graft copolymer is provided exhibiting certain advantageous properties.

Title: Nitrogen generation method and apparatus
Inventor: NAUMOVITZ JOSEPH P
IPC: F25J3/04
Filed: 1996-10-09
Abstract: A method and apparatus for generating nitrogen from the separation of air in a single column nitrogen generator. Nitrogen rich vapor is condensed to form reflux through the vaporization of an oxygen-rich liquid stream produced as column bottoms. The vaporized oxygen-rich stream is in part recompressed in a recycle compressor, cooled and reintroduced back into the column to increase nitrogen production. The vaporized oxygen-rich stream is also in part expanded with the performance of work. The work of expansion is applied to the compression. A supplemental refrigerant stream produced by a nitrogen liquefaction unit allows the nitrogen to be taken as a liquid and increases the amount of work of expansion able to be applied to the compression.

Title: Asphalt plant with collapsible material bin
Inventor: DAHL JOEL MILLARD
IPC: B60P3/06
Filed: 1996-11-22
Abstract: The present invention discloses a method of constructing collapsible raw material bins for a portable asphalt plant in such a manner that said raw material bins may be located on the same flatbed semi trailer as the rest of the asphalt plant. The collapsible material bins are constructed in such that, when not in use, they may collapse in an accordion-like fashion upon one another. This is done by having one wall of two of the bins constructed so that it may slide in and out within the respective bin. Additionally, the bins themselves are mounted on a sliding rail system which allows for the necessary movement of the bin walls. The end result of this design is that it provides a compact enough raw material bin system to allow it to be constructed on the same flatbed trailer as the asphalt tumbler, and yet provides a large enough raw material bin capacity to allow for the efficient operation of the portable asphalt plant.

Patent CA-2199631-A1 (CA)
Title: Impedance monitoring system
Inventor: BAURA GAIL D
IPC: A61M5/00
Filed: 1995-09-11
Abstract: Impedance to fluid flow in a fluid delivery line is measured. Two techniques are used depending on the flow rate selected. For high flow rates, the pump (18) is controlled to vary the flow rate and the change in pressure is divided by the change in flow to directly determine the resistance. For low flow rates, a processor (14) controls the pump (18) to pump flow quantities in accordance with a pseudo-random binary code. The resulting pressure signal sensed at the conduit (22) is decoded in accordance with that code. Pressures received during code periods of no flow are subtracted from pressures received during code periods of flow. Pressure offset is also removed and a least squares estimation approach is used with a linear prediction model to determine impedance. The coefficients determined in the model are used to calculate the resistance to fluid flow of the system. A quality supervisor monitors the resistance determination process and controls the display (28) of resistance depending on the quality determined. A resistance display (28) continuously displays the resistance of the system.

Filed: 1997-06-06
Abstract: A knit slide fastener stringer including a fastener tape knitted in a warp-knit ground structure and having along one longitudinal edge an element-attaching portion, and a continuous fastener element row knitted in and along the element-attaching portion of the fastener tape and secured by two or more wales of anchoring chain stitch yarns simultaneously with the knitting of the fastener tape.  In this knit slide fastener stringer, successive needle loops of each of the two or more wales formed of the anchoring chain stitch yarns press the continuous fastener element row toward the warp-knit structure of said fastener tape from the upper side, and successive sinker loops constitute part of the ground structure. And a number of warp-inlaid yarns are each laid in and interlaced with at least part of the successive sinker loops.  The result is that the ground structure of the element-attaching marginal portion is kept in accurate size to prevent the coupled fastener element rows from locally splitting.
