Title: Process for the fluorination of synthetic resin articles
Inventor: REBHAN DIETER
IPC: C08J7/12
Filed: 1988-11-25
Abstract: Articles to be fluorinated must be brought into contact with fluorine-containing gas. Elemental fluorine is a hazardous material whose handling requires a complex plant design. In a particularly safe process for fluorinating plastic containers, the fluorination is carried out by introducing the article into a gas-tight chamber and positioned therein, and a fluorinating treatment gas is then produced with the aid of a plasma burner from a base gas mixture containing a fluorine-containing compound.

Title: Welding apparatus
Inventor: JOHNSON MICHAEL J
IPC: B29C65/18
Filed: 1999-07-09
Granted: 2003-09-03
Abstract: A conduction welding apparatus and method for bonding abutted thermal plastic tubular end portions is particularly suitable for welding PFA. In a preferred embodiment, a folding weld head embraces the abutted the tubular end portions to be welded, each tubular end portion including a flange spaced from the surfaces to be joined. The weld head includes means for securing the flanges within the weld head and further include bias means. The bias means provide an inward axial bias on the adjoined tubular end portions when the tubular end portions are displaced axially outward from the weld head due to the expansion of the plastic during the weld process. The bias means in a preferred embodiment is substantially inoperative prior to the weld and provides bias, or a substantial increase in bias, when the flanges are displaced due to the expansion of the molten PFA during the weld process. In a preferred embodiment, the securing means comprises a pair of clamps which each attach to and encompass the respective tubular end portions at the end portion flanges. The tubing clamps fit into recesses in the weld head. In such a preferred embodiment the bias means is provided by a spring loaded plate which is deflectable in an axial direction outward from the weld head. The invention also includes a process for accomplishing a weld with the described apparatus.

Title: PABX common channel relay system
Inventor: BABIARZ JOZEF Z
IPC: H04Q11/04
Filed: 1992-09-29
Granted: 1996-01-17
Abstract: A high speed communication link between peripheral nodes and a single multi-link layer protocol (MLAP) controller with an integrated HDLC framer in a main control complex. Peripheral nodes contain a very simple control that forwards all the HDLC D-channel data from the peripherals to a single MLAP controller, thus making the peripheral nodes small in physical size, extremely flexible to connect to new interfaces and very portable. Accordingly it facilitates the efficient distributed deployment of the PABX. Using the described system, the PABX itself may be distributed around a building, using a backbone high speed link. Peripheral nodes may be located at various places in a building with peripherals such as line interfaces and associated digital telephones at locations as needed. They need not be centralized, adjacent the main control complex, as is now required. This facilitates the provision of a building with a flexible communication system having substantially reduced wiring requirements. The bit rate of transmission of HDLC formatted data is changed from 16 kb/s or 64 kb/s to 2.048 mb/s and visa versa. Plural modified HDLC packets are multiplexed to one physical link that is terminated by an HDLC framer inside the multi-link access protocol controller or, from one MLAP controller, many peripherals can be accessed and controlled. The functions of the present invention are transparent to the end-point HDLC framers and hence to the link layer protocol and peripheral software.
