Title: Apparatus and process for a polycondensation reaction
Inventor: BHATIA KAMLESH KUMAR
IPC: B01J19/18
Filed: 1997-03-24
Abstract: An improved process and apparatus for the production of a polyester or other condensation polymer is disclosed. In particular, polymerization is conducted in a reaction vessel equipped with a specially designed agitator that exposes the polymer melt partially filling the reaction vessel to inert gas flowing through the vessel. The agitator comprises a plurality of elements that lift a portion of a polymer melt in the reaction vessel and generate films of the polymer melt which films extend in planes that are parallel to the axis of the agitator and the flow of gas through the reaction vessel. In a preferred process, a melt of bis(2-hydroxyethyl)terephthalate, or its low molecular oligomers, obtained by esterifying terephthalic acid or transesterifying dimethyl terephthalate with ethylene glycol, is contacted with an inert gas at about atmospheric pressure in order to remove the reaction by-products and facilitate polymerization.

Abstract: A divider plate preferably made of flat plastic sheet inserted into built up channels on the upper and lower sides and bottom of a multigang box is disclosed. The channels are strategically placed within the multigang box to allow the divider plate, when inserted, to create distinct and separate single gang openings. The channel walls form, with the edges of the divider plate, a triple layer barrier protection against wires from one opening from entering an adjacent opening, such as through a gap between the divider and the box. In another embodiment, the multigang box is molded with a groove to accept the divider plate. Also disclosed is a divider plate permanently embedded in the box, as by adhesive or integrally molding, to divide compartments while eliminating the potential for gaps to exist.

Title: Method and apparatus for automated provisioning and billing of communication services
Inventor: FRASER ALEXANDER GIBSON
IPC: H04Q3/00
Filed: 1997-01-16
Abstract: A method for operating a communication network where the tie between the provisioning of and billing for service and the terminating point of the telecommunication network to which service is provided is severed. Instead, an association is maintained between the provisioning and billing for service and a piece of telecommunication equipment, regardless of the point of that equipment's connection to the network. This enables a customer to appear at any point of the telecommunication network and still obtain service, and it allows the telecommunication carrier to streamline the processes of provisioning, billing and collecting of moneys. An account is maintained by the telecommunication carrier for a specific piece of telecommunication equipment. The account is established by forwarding to the telecommunication carrier a service request including information that uniquely identifies the telecommunication equipment and information that enables the carrier to bill the customer. The carrier optionally establishes a relationship with a credit card enterprise to pay for services rendered to the registered equipment.

Title: Arc fault detector with circuit interrupter
Inventor: ROSE WILLIAM J
IPC: H02H3/33
Filed: 1998-12-16
Abstract: An arc fault detector embodied as both a stand alone device and in combination with a circuit interrupting device such as a ground fault circuit interrupter (GFCI) functions to provide protection from potentially dangerous arc fault conditions. The device utilizes line side and load side pickup coils to permit distinguishing between arc faults occurring on the line side and the load side of the device. The arc fault circuit interrupter (AFCI) circuitry portion of the device shares components from the GFCI circuitry portion as an integral part of its functionality. The AFCI utilizes the electromechanical power carrying portion of the GFCI, including the AC line disconnect circuitry, the power supply and the physical housing. In addition, the AFCI employs quantitative detection using variable gain control in combination with either a load disconnect or audible/visual alarm indication. The device also includes a timer circuit, which permits the user to temporarily inhibit or disable the arc detection, and selective frequency filtering permitting are detection in the presence of power line carrier communications. In addition, the device includes communication means to permit the device to communicate the occurrence and location of an arc fault to a centralized monitoring station.

At least one of the two field generators generates a magnetic field whose amplitude is variable over time so that the resultant is a magnetic field moving in the field plane having a variable amplitude and a direction moving at an angular velocity such as to obtain the highest possible gradient of the vector product.
