Title: Process for the manufacture of poly(hydrocarbylene aryl phosphate) compositions
Inventor: BRADY BILL
IPC: C07F9/12
Filed: 1994-03-02
Abstract: Arylene poly (diarylphosphate) compositions can be formed by a process which comprises: (a) forming a reaction mixture comprising diaryl halophosphate and, as by-products, a mixture of monoaryl dihalophosphate and triarylphosphate, by reaction of phosphorus oxyhalide and a phenol in a first reactor; (b) if a preponderance of lower oligomers is desired, optionally transferring the reaction mixture from (a) to a subsequent reactor where at least a portion of the monoaryl dihalophosphate is recycled to the first reactor for reaction with the phenol contained therein to form additional diaryl halophosphate in the first reactor and the reaction mixture in (b) becomes enriched with diaryl halophosphate to ultimately favor the ultimate formation of a product of lower molecular weight distribution; and (c) reacting the product from (a) or (b), as selected, with an aromatic diol to form the arylene poly (diarylphosphate) product.

Patent CA-2121738-A1 (CA)
Inventor: HEISMANN FRED LUDWIG
IPC: G02F1/035
Filed: 1994-04-20
Abstract: The effects of polarization dependent hole burning and/or polarization dependent loss are reduced by modulating the state of polarization (SOP) of an optical signal being launched into the transmission path periodically between first and second states of polarization of at least one pair of orthogonal states of polarization. Ideally, the launched modulated signal should spend equal time intervals in both states of the orthogonal pair. In one exemplary embodiment, the SOP is modulated such that it moves along a great circle on the Poincare' sphere. In another exemplary embodiment, the SOP is modulated such that it traces a complete great circle on the Poincare' sphere. In a preferred embodiment, a complete great circle is traced at a uniform speed on the Poincare' sphere.

Patent CA-2124707-A1 (CA)
Inventor: DORWARD SEAN M
IPC: H03M13/35
Filed: 1994-05-31
Abstract: A method of tailored error protection coding is disclosed. An illustrative coding method according to the present invention concerns encoding a first signal and a second signal to provide error protection for the signals, wherein the first signal requires greater error protection than the second signal. According to the method, the first signal is encoded with a first error protection code. The encoded first signal is then combined with the second signal. The combination of the encoded first signal and the second signal is further encoded with a second error protection code to generate a combined error protected signal, wherein the firstsignal is coded with both the first and second error protection codes. A second embodiment concerns the use of separate coders which apply different error protection codes to two signals. The two encoded signals are then combined into a single signal.

Title: Integrated food sorting and analysis apparatus
Inventor: WEST JAMES K
IPC: B07C5/342
Filed: 1995-01-13
Abstract: An integrated bulk food sorting and analysis apparatus comprises a wide-belt product conveyor which receives and conveys a laterally-distributed stream of bulk food articles past a product diverter. An upstream camera is positioned to view the stream of food articles upstream of the product diverter.  Automated sorting logic is responsive to the upstream camera to individually determine optical characteristics of each food article. The product diverter is responsive to the automated sorting logic to divert a portion of the food articles from the stream depending upon their individual optical characteristics. The apparatus also includes a downstream camera positioned to view the stream of food articles downstream of the product diverter. A data processor is responsive to both the upstream camera and the downstream camera to periodically examine samples of food articles and to calculate upstream and downstream quality statistics regarding the stream of food articles. The data processor is programmed to compare the calculated upstream and downstream quality statistics to derive diverted product quality statistics regarding the food articles diverted by the product diverter. The data processor also calculates settings for the automated sorting logic based upon the calculated quality statistics.

Abstract: An elevator car braking system in which a pair of brake shoes engage and grip the hoisting ropes, part of the hoisting apparatus or the car guide rails when compressed springs, which are normally held in a compressed state by an electrically operable locking assembly, are released. The springs are compressible by a fluid operable piston and cylinder assembly. The springs move a cam follower, linked to one of the shoes, along cam surfaces shaped and disposed to cause the cam follower to move one brake shoe toward the other brake shoe. The locking assembly is responsive to car speed and/or movement of the car from a floor with its doors open. Switches operable by the cam follower control the car electrical controls so that movement of the car is prevented when the springs are not compressed and when there is excessive shoe wear.

Title: Drilling a well with gas supply in the drilling liquid
Inventor: GRAY BENJAMIN
IPC: E21B47/18
Filed: 1995-01-20
Abstract: A conventional well bore drilling system includes a coiled tubing mounted on a reel and connected to a mud supply for supplying mud through the tubing to a downhole end of the tubing to which is attached the downhole drilling tool. The system is modified by the addition of an inner tubing attached to the reel shaft and extending through the outer tubing to the drilling tool. The drilling mud is supplied in the space between the inner and outer tubes and a gas is supplied through the inner tube. The gas is vented through a coupling at the drilling tool into the well bore so as to enter the well bore and reduce the hydrostatic head of the fluids within the well bore to an under balanced condition below the pressure of the producing zone. As the gas is supplied through the inner tube, it is maintained separate from the liquid outside the inner tube and accordingly can be by passed into the well bore without entering the downhole MWD or motor drive systems and in addition the mud pulses generated by the downhole MWD system can be communicated through the drilling mud in conventional manner without losses due to gas within the liquid.
