Abstract: Distributed Reference Links (“DRLs”) for managing the referential integrity between objects in a distributed directory server system are described. In a preferred embodiment, DRLs specify a set of attributes, precedents, and algorithms that define how a resource can notify other resource managers of a change in the identity information of one of its objects. Using DRLs, before an external reference to an object is created, a “UsedBy” attribute identifying the partition that will include contain the external reference is added to any R/W replica of the object prior to the creation of the external reference object.

Abstract: A magnetic brush development station includes, a housing forming a reservoir for developer materials. A plurality of augers are located in the housing for mixing developer material. A development roller is mounted within the housing for delivering developer material from the reservoir to a development zone. The development roller includes a core magnet inside a shell, having relative rotation. The core magnet extends less than the entire length of the development roller such that a developer nap on the shell does not extend to the respective ends. A metering skive controls the quantity of developer material delivered from the reservoir. A metering skive is positioned parallel to a longitudinal axis of the development roller at a location upstream in the direction of shell rotation prior to the development zone. A magnetic seal is located in association with the skive at each end to substantially prevent leakage of developer material.

A development roller is mounted within the housing for delivering developer material from the reservoir to a development zone. A plurality of rotatable augers are located in said housing for mixing developer material within the reservoir, and are arranged substantially side-by-side with respective parallel longitudinal axes, the most outboard of the plurality of augers being positioned to be raised and toward the center with respect to the housing of the development station. Accordingly the overall width of the development station is reduced while maintaining centerline distances between each of the plurality of augers so that individual augers do not interfere with one another.

Abstract: A preamplifier for a resistive transducer, configured to generate an amplified output indicative of potential difference across the transducer (while the transducer is biased and in the presence of a magnetic field) and to generate a resistance signal indicative of the transducer's resistance, and a method for measuring the resistance of a resistive transducer during operation of the transducer in the presence of a changing magnetic field. The preamplifier preferably includes circuitry for generating a current signal indicative of the instantaneous current through the transducer and analog divider circuitry for generating the resistance signal from a signal indicative of the potential difference across the transducer and the current signal. When the resistance signal is an analog signal, the preamplifier can include circuitry for processing the analog resistance signal to generate a word of binary data indicative of a value proportional to the transducer resistance.

Abstract: A loop detector circuit for detecting the loop current of a telephone circuit in a ground start mode and a normal mode which obviates the need for a separate TIP ground detector circuit. A pair of light emitting diodes (LED) 52, 54 are associated with a photoelectric device, such as a phototransistor 56, 58, connected across TIP and RING with a series resistor. Each resistor 60, 62, is selected to provide a predetermined voltage drop during a ground start mode and a normal mode, thus enabling the loop detector to detect loop current during both modes. The loop detector circuit is thus able to detect the off-hook status of a subscriber handset during a ground start mode without the use of a separate TIP ground circuit.

Abstract: A composite material rotor is disclosed which is made from a plurality of stacked and bonded epoxied filament wound discs, each disc providing a specially wound construction so that the modulus of the rotor body may be varied in proportion to the maximum stress encountered by the rotor during ultracentrifugation. Such a layered disc assembly allows the rotor to be fine-tuned to respond to a variety of stress encountered during ultracentrifugation. Where upper hoop stress is greater, upper disc 28 might be wound using a higher modulus filament fiber than the fiber used by disc 26.

Abstract: A method of and device for machining workpieces on a multi-tool machine provided with a numerical control system. For the automatic, simultaneous execution of machining instructions which relate to the control of more than one tool, instruction groups are formed from machining instructions which can be simultaneously executed on the basis of their mutual independence. Within an instruction group, partial dependency can exist, on the basis whereof a subsequent instruction is executed, after a condition imposed in a previous instruction has been satisfied.
