Abstract: A multicapillary bundle for use in a gas chromatograph. Each of the capillaries in the bundle is formed using a coating solution containing a stationary phase and a solvent. The capillaries are coated with stationary phase by reducing pressure at a vacuum end of the capillary and creating a moving interface between the coating solution and a film of stationary phase deposited on each of the capillaries. The reducing pressure at the vacuum end of the capillary and the temperature of the capillary are controlled to maintain motion of the moving interface away from the vacuum end of the capillary. Maintained movement of the interface prevents recoating of the stationary phase. A heating wire and capillaries are embedded in a thermally conductive polymer to create a highly responsive method of heating the multicapillary column. An electronic control device controls the feedback temperature of the multicapillary column using the heating wire.

Abstract: NTLM compliant clients and servers are mutually authenticated in accordance with the Kerberos authentication protocol without migrating the clients or servers to Kerberos. With an RPC framework, a target name is generated from the server host name. The target name includes an indication that mutual authentication is to be accomplished. During the initial stages of the RPC session, the target name is sent to the server. If the server recognizes the target name, the client and server are mutually authenticated in accordance with the Kerberos protocol. If the server does not recognize the target name, the client is authenticated in accordance with the NTLM authentication protocol.

Abstract: Code information is marked by tags and tags are embedded into pieces of code or files called “codetags” that map tags to pieces of code. These tags can then be updated, searched, sorted, recombined, and tracked, among many other feedback mechanisms. These tags and their feedback mechanisms help to illuminate the engineering metadata and business metadata of pieces of code so as to help engineering management and business management of companies to better guide their software resources.

Abstract: Modifications to security information associated with accessing an object are evaluated. Evaluations are performed to determine if excessive access rights or permissions have been granted on the object, which could lead to compromised security. A security verifier intercepts the security information and determines if an identified owner constitutes an untrusted security entity. If so, a notification to that effect is issued. The security verifier also determines whether access rights granted to other entities create a security threat. If so, a notification to that effect is issued. Multiple levels of potential threat may be employed, and notifications of varying severity may be used to illustrate the disparity between the multiple levels of threat.

Abstract: A master controller and various nodes capable of performing disparate functions are configured to cause devices to manipulate an aircraft seat. The nodes operate independently and without interference of the master controller. The master controller provides programs to the nodes. A node initiates a program when commanded to do so by the master controller resulting in a device manipulating an aircraft seat or otherwise operating in conjunction with the aircraft seat. The node also monitors and provides various real time information and performs calibration, power management, diagnostic and other similar types of operations.

Abstract: There is disclosed a process for the mineralization of collagen fibers whereby collagen fibers formed from collagen are contacted with a solution of calcium and phosphate ions under conditions to effect nucleation and in-vitro growth of mineral crystals within and on the surface of the collagen fibers to form intact collagen fibers with subfibrillar substructure and wherein preparations of such mineralized collagen fibers are used in bone replacement therapy as well as to induce repair in bony defects.

Abstract: A method of operating a transport refrigeration system having a compressor driven by a prime mover at a selected one of high and low speeds, an evaporator, and an evaporator blower driven by the prime mover. Refrigeration control provides an error value which controls the temperature of a load space to a predetermined set point via heating and cooling modes. The method includes the steps of driving the compressor at high speed during pull down, and injecting hot gas into the evaporator when the error is reduced to a predetermined value. The prime mover is maintained at high speed, to keep evaporator air flow at a high rate, continuing a relatively rapid temperature pull-down across the entire load space. The speed of the prime mover is reduced to low speed when the error is further reduced to a second value, which also initiates suction line modulation while maintaining hot gas injection.

Abstract: A method of determining if the refrigerant charge in a refrigeration system is within an acceptable range, including the step of developing a model evaporator temperature-versus-time signature for a system known to have a recommended refrigerant charge level. The model developing step includes the steps of isolating an evaporator from a space to be conditioned by the system, operating the system in a cooling mode to cool the evaporator, trapping refrigerant in the cooled evaporator to introduce an instability into the cooling cycle, and continuing the cooling mode for a time sufficient for a system having an acceptable charge level to recover from the trapping step. A test signature is then provided for a system to be checked, using steps similar to those used to develop the model signature, and the test signature is compared with the model signature to determine if the refrigerant charge is within an acceptable range.

Abstract: A method of controlling a refrigeration system by determining an average air temperature by sensing and averaging evaporator return and discharge air temperatures, and developing an average error by using the average air temperature and a selected set point temperature. The average air temperature is then used to calculate a proportional error and an integral error, and the discharge air temperature is used to calculate a floor error. The proportional error, integral error and floor error are weighted by predetermined gain factors and then summed to provide an error signal which is used to modulate the capacity of the refrigeration system, with the control mode depending upon the location of the error signal relative to set point.

Abstract: A power line carrier communication system for monitoring refrigerated containers which includes a master monitoring unit and a first power line interface which interchange messages in a first format. The first power line interface translates the first format to a second format suitable for power line environment, and messages in the second format are applied to a power line. Remote monitoring units receive the messages from the power line, and they return messages to the power line containing status data relative to refrigerated containers. The second format includes a message starting preamble having a duration and logic level which is not duplicated by normal operation of the apparatus, enhancing the probability of proper message synchronization and reception over noisy power line environments.

Abstract: A microprocessor based system monitors and controls a transport refrigeration system having a two speed compressor coupled to a condenser and an evaporator and further having two speed condenser and evaporator fans, a refrigerant modulating valve, and heater means to cool or heat a served space. A keypad is provided for operator entry of the temperature setpoint and for display selections. Return air and discharge air temperature sensors provide signals to the microprocessor for temperature control. The microprocessor is programmed to sequence or control the compressor, the fans, the modulating valve and the heater means for temperature control in accordance with one of four stored algorithms. One of the temperature sensors is used for control, and if it is detected to have failed automatic switchover is made to use of the other temperature sensor for temperature control.
