Abstract: A method and apparatus for the continuous separation of a target protein from a protein mixture containing two or more proteins and at a pH equal to the pI of the target protein is disclosed. The method and apparatus employ a non-ionic, non-electrically conductive porous conduit (10) through which the protein mixture is passed. The conduit is subjected to the influence of an electrical field substantially perpendicular to the flow of fluid therethrough resulting in movement of all charged protein from the conduit lumen. The target protein, which is unaffected by the electric field since it is not charged at a pH equal to its pI, is collected from the conduit outlet in substantially purified form.

Abstract: Advanced packaging techniques are utilized to provide updated packaging for optical transmitters and receivers. In particular, the hybrid integrated circuit (HIC) used to form either the transmitter or receiver circuitry in the prior art has been replaced by a plastic dual-in-line package (DIP) (66). The DIP includes specialized leads (prongs) (68, 70) formed through the short end of the DIP to provide direct connection to the optical device (61). These endprong leads thus significantly decrease the parasitic capacitance associated with conventional DIP connections. A capacitor may be molded into the DIP across the power supply leads to provide filtering for the package. Thermal dissipation is provided by two separate means in this package. First, the leadframe of the DIP is formed to include relatively long leads (72) which extend through the bottom of the package to carry away the heat generated by the integrated circuit and the DIP itself may be disposed on a thermally conductive substrate which will also dissipate heat generated by the integrated circuit (80). Second, the metal cover (76) of the package is attached to the optical device by a thermally conductive epoxy to provide a heat path for the optical device. Molded plastic piece parts are utilized to form the optical sleeve (58) and an optical frame assembly.

Abstract: An in-line strapping system which is particularly adaptable for strapping a compressible stack of sheet material includes a stack feeding mechanism which captures and holds the stack with its vertical side faces squared through the strapping cycle. A pair of vertically disposed compression belts captures the stack fed from an upstream squaring mechanism (10) and feeds the stack into a strapping station (11) to partially encircle the stack with a strap disposed in the path of movement. Only one lateral side of the stack is captured between the compression belts such that the stack is held in cantilevered fashion in the strapping station with the opposite lateral side unsupported. A rotary strap arm (40) supports the partially wrapped strap and carries it around the unsupported rear portion of the stack to a sealing position overlapping the free end of the strap beneath the stack. A heat sealing apparatus seals the overlapping portions of the plastic strap, simultaneously cuts the strap to provide a new free end and clamps the new free end in a preliminary holding position. The strapped stack exits the system and the rotary strap arm continues in the same direction to an upper position and repositions the strap in the path of the next incoming stack. The heat sealing apparatus and associated strap clamping mechanism are operated by a common camshaft adapted to provide one complete operating cycle in a single revolution. The unidirectional rotation of the rotary strap arm allows the use of much simplified strap clamping mechanisms.

Abstract: An animal-resistant optical fiber cable (20) includes a core (22) which comprises a transmission medium and a sheath system. The sheath system includes an outer jacket (65) and a dielectric armor (40) in the form of a shell. The shell comprises a plurality of longitudinally extending preformed segments (42-42) each having a cross section transverse to a longitudinal axis of the cable each of which covers less than half of the periphery of the core. Further, the shell segments are stranded helically about the core with at least portions of longitudinal edge surfaces of adjacent segments being in engagement with each other. The shell segments not only provide rodent protection for the cable, but also they provide suitable tensile and compressive strength. Further, because the cable in the preferred embodiment has an all-dielectric sheath system, it is inherently lightning, corrosion and EMP resistant.

Abstract: Stations in a sequence accepting a vector from preceding stations in the sequence communicate data packets to other stations in the sequence. Each station receiving the vector becomes spliced out of the sequence by communicating such a desire to the preceding station, which then provides for the passing of the vector to the station following the next station. Alternatively, an individual station (not in the sequence) between the communicating and next stations can be spliced into the sequence by communicating to all stations such a desire before any response from the next station. If the next station does not respond to the communicating station, the communicating station can splice the next station out of the sequence and provide for the passing of the vector to the following station. Some or all stations may be in a performance mode higher than a set-up mode. Any station preprogrammed to be active in the sequence and to operate in the performance mode may initiate the operation of the performance mode sequence when the stations are operating in the set-up mode. In each cycle, if no station in the performance mode requests the operation to continue in such mode, the stations will revert to the set-up mode. If several successive stations become lost from the sequence, the sequence becomes patched by a special communication from each station to patch the next station into the sequence. In a start-up operation, a first station identifies itself by a communication to the other stations and the special communication in the sequence described in the previous sentence to progressively patch the other stations into the sequence.

Abstract: In an optical fiber laying structure for an electric power cable line trouble occurrence location detecting system for detecting a trouble occurrence location by laying an optical fiber (5A to 5D) along an electric power cable line (1), the portion of the optical fiber laid along the cable of one of the two adjacent sections (4A to 4D) is superposed on the portion of the optical fiber laid along the cable of the other sections in an area in the vicinity of the boundary (7A to 7C) of the electric power cable line. Thus, if a temperature rise occurs due to a trouble such as a ground-fault in the boundary area, the temperature peak position, i.e., the trouble occurrence location can be detected by the two different optical fibers. Therefore, the trouble occurrence location in the boundary area can be accurately detected.

Abstract: A magnetic thin film structure comprising a first layer (12) of magnetic material having a low anisotropy H k  magnetically coupled to a second layer (14) magnetic material having a high anisotropy H k  and a low coercivity. The laminate provides a dual anisotropy behavior such that the laminate exhibits a high initial permeability at relatively small applied fields during the read operation and a high anisotropy at high applied fields during the write operation. The laminate of the present invention reduces inductive head domain instability produced by the write operation while maintaining high reproducing sensitivity during the read operation. Use of the higher H k  material also reduces the sensitivity of the head performance to variation in process-induced stresses.

Abstract: Apparatus having reduced background for measuring radiation activity in aerosol particles. A continuous air monitoring sampler is described for use in detecting the presence of alpha-emitting aerosol particles. An inlet fractionating screen has been demonstrated to remove about 95% of freshly-formed radon progeny from the aerosol sample, and approximately 33% of partially-aged progeny. Addition of an electrical condenser and a modified dichotomous virtual impactor are expected to produce considerable improvement in these numbers, the goal being to enrich the transuranic (TRU) fraction of the aerosols. This offers the possibility of improving the signal-to-noise ratio for the detected alpha-particle energy spectrum in the region of interest for detecting TRU materials associated with aerosols, thereby enhancing the performance of background-compensation algorithms for improving the quality of alarm signals intended to warn personnel of potentially harmful quantities of TRU materials in the ambient air.
