Title: Atm cell assembling and disassembling system and method
Inventor: NISHINO TETSUO
IPC: H04L47/43
Filed: 1992-08-27
Abstract: In an ATM cell assembling and disassembling method for a communications network having first and second communications nodes, HDLC data is transferred from a first terminal to the first communications node via a first transmission line, the HDLC data conforming to an HDLC format.  It is started to assemble, in the first communications node, at least one cell from the HDLC data when data which is contained in the HDLC data and equal to one cell has been received.  Then the above at least one cell is transferred from the first communications node to the second communications node. Disassembly is started, in the second communications node, of the above at least one cell to thereby generate original HDLC data when a fluctuation compensation time has elapsed after a first cell among the above-mentioned at least one cell is received by the second communications node.  The fluctuation compensation time is based on a maximum fluctuation time of a route connecting the first and second communications nodes to each other as well as a bit rate of the first transmission line.  Finally, the original HDLC data is transferred to a second terminal from the second communications node via a second transmission line.

Title: Enzymatic synthesis of soluble phosphatides from phospholipids
Inventor: TREMBLAY PAUL A
IPC: C07F9/10
Filed: 1991-04-16
Abstract: A method of preparing a soluble monovalent salt of a phosphatidyl ester which comprises reacting a phospholipid with a primary alcohol in the presence of an enzyme catalyst in a divalent cationic buffered solution and a water immiscible non-ether solvent that does not inactivate the enzyme, to form a divalent cationic salt of the phosphatidyl ester, and suspending the product in the presence of a stoichiometric amount of a monovalent cationic salt whose anion forms an insoluble salt with the divalent cation. The use of Centrifugal Partition Chromatography facilitates the enzyme reaction. The monovalent salt is preferably an ammonium/sodium mixed salt.      Phosphatidyl ester salts prepared by processes disclosed herein are useful products for making liposomes and lipid-based complexes.

Title: Plastic extruder with automatic shut-off valve
Inventor: DURINA MICHAEL F
IPC: B29C45/18
Filed: 1992-10-23
Abstract: ABSTRACT OF THE DISCLOSURE           A plastic extruder comprising a rotating helical screw within a cylindrical shell. An automatic shut-off valve is mounted at the forward end of the helical screw.  The valve includes a unitary or integral valve body and a poppet which is axially  movable and is rotatable relative to the valve body.  A rearwardly extending axial bore is provided at the forward end of the screw and the valve body extends into and is secured to the screw within said bore.  The poppet has an axial stem which extends through the valve body into the axial bore.  A compression spring is mounted on the rearward end of the poppet stem to act cooperatively with respect to the poppet to urge the poppet against a seating surface of the valve body and maintain the valve in a normally closed position.  Flow of plastic through the valve upon rotation of the screw causes the valve to open.          However, the valve automatically closes upon cessation of screw rotation to prevent back-flow of plastic during the injection step.

Inventor: GELLERT JOBST U
IPC: B29C45/26
Filed: 1992-11-19
Abstract: An injection molding nozzle and method of making it having an electrical heating element extending in a pair of alternating coils in a spiral channel around a central melt passage. The heating element has a U-shaped bend near the forward end of the nozzle and two ends at an external terminal-near the rear end. A central wire in the heating element has a fine coiled heating portion extending between two larger diameter conductive portions which extend to the terminal. One of the conductive portions of the central wire is a predetermined length longer than the other and extends in one of the alternating coils of the heating element along a rear portion of the nozzle adjacent the terminal. The heating portion of the wire extends in both of the alternating coils of the heating element along a forward portion of the nozzle so the heating element provides substantially less heat along the rear portion than along the forward portion of the nozzle.

Title: Microwave monolithic integrated circuit testing
Inventor: KRUMM CHARLES F
IPC: G01R31/26
Filed: 1993-12-10
Abstract: MICROWAVE MONOLITHIC INTEGRATED CIRCUIT TESTING                                ABSTRACT The present invention performs RF performance measurements on basic transistors of a microwave monolithic integrated circuit while it is being fabricated. The circuitry necessary to assess the performance potential at the frequency and power levels of interest is provided by incorporating matching elements onto RF probes used for in-process tests. This invention measures the RF performance potential of GaAs monolithic microwave integrated circuits at an early stage in the process before expen-sive process sequence has been completed. The essence of the invention is that the transistors are measured with an RF probe that has RF matching circuitry included as an integral part of the probe. Consequently, the performance potential of circuits on the wafer is assessed at the earliest possible point in the manufacturing process; specifically as soon as Schottky barrier gates have been deposited. This in-process measurement approach may be applied to any microwave monolithic integrated circuit. Once thecorrelation between in-process and post-process measurement results are established, the present method may be used to routinely screen wafers, thereby saving roughly two-thirds of the processing costs of "RF bad" wafers.

Title: Sensor head for a fiber-optic current measuring device
Inventor: MEIER MARKUS
IPC: G01R15/24
Filed: 1994-02-03
Abstract: ABSTRACT OF THE DISCLOSURE        The sensor head (1)  is intended for a fiber-optic current measuring device.  It exhibits a twisted low-birefringence LB fiber (14) which is guided around a current conductor (2) and serves to conduct polarized light. Using the LB fiber (14), the Faraday rotation of the polarized light, which rotation is generated by the magnetic field (H) of the current (J) to be measured, is detected. The LB fiber (14)  is spliced at its two ends in each instance with one of two polarization-con-serving, light-conducting HB fibers (6, 7), one (6) of which supplies the polarized light. The two HB fibers (6, 7) are secured in each instance in the vicinity of the two splice locations (19, 20) with the absorption of the torsional force generated by the twisting of the LB fiber (14).        In spite of having a simple and sturdy struc-ture, the sensor head (1) is distinguished by a high degree of measurement accuracy.            (Single Figure)
