Abstract: A roll press with two press rolls which together form a press gap and whose axes are situated in a press plane. A journal is disposed on the ends of each roll, with pillow blocks for receiving the journals, with a rack for supporting the pillow blocks, and with tie rods which are arranged on both sides of the press plane and at least approximately parallel to it. Cradles are provided which support the pillow blocks. Between the cradles and the pillow blocks is an articulated joint which enables the pillow blocks to pivot about an axis which extends perpendicularly to the press plane and essentially in the axial plane of the respective roll.

Abstract: A soil sampling probe includes a handle for grasping the probe and a rod member extending therefrom. The handle comprises an annular ring integrally formed with the rod member. A number of soil sampling slots are formed along in the rod member for collecting and retaining soil samples. The soil sampling slots slope inwardly and downwardly in the rod member. A substantially vertical rib is formed adjacent the slots to reinforce the rod member adjacent the soil sampling slots.

Abstract: Apparatus and method for detecting rotor (12) position in a switched reluctance motor (18) having multiple stator phases (A-A', B-B', and C-C'). A multiplexer (48) intermittently connects a known resistor (54) to a non-conducting stator phase. Circuitry (62 and 68) detects the amplitude of the current passing through the resistor (54) and the phase difference between the varying voltage and the current passing through resistor (54). The resulting signal is proportional to the position of rotor (12).

Abstract: In telecommunications switching system, software is frequently modified, enhanced or replaced altogether by new versions. The implementation or integration of the new or revised software into the operational system must be accomplished in accordance with strict requirements for not disturbing the ongoing activities of the system. Therefore, it is desirable that the system not be halted while the change to the new software is made. Rather, the preferred approach is to be able to replace software modules with new versions on the fly, during system operation. The smooth modification made possible in the disclosed system allows such changes with minimal disturbance to ongoing activities. The disclosed system provides the ability to change software during operation by treating the dynamic operations of a telecommunications system as a set of parallel, independent transactions, with each transaction consisting of a series of connected activities.

Abstract: In a radio communications system having at least one base station, the base station including a plurality of transceivers, a control method and apparatus includes the steps of comparing the number of transceivers in a call state to a first predefined number. If the number of call state transceivers is greater than the first predefined number, then all of the idle transceivers except at least one are switched off. If the number of call state transceivers is less than the first predefined number, then all excess idle transceivers are switched off. Also, after switching off the first subset of the plurality of transceivers, a second subset may be switched off after waiting a predetermined time period. The number of operational transceivers in the second subset is less than in the first subset.

Abstract: A method for restructuring input data having a prespecified input data structure with a data management engine, such as a translation engine, which is dynamically configured by the input data to conform the input data to an output data structure. When the data management engine takes the form of a translation engine, capability exists to translate data to and from various electronic data interchange (EDI) formats. Because the data management engine is dynamically configured by the input data, the translation process is independent of the specific details of EDI protocol and capable of coordinating multiple data sources/destinations without requiring any recoding of the engine. Initially, data protocol utilized in the data interchange system is ascertained. Then, the protocol data related to the data protocol and protocol processing instruction data is initialized.

Abstract: A screw gun drive is adapted to adjust itself automatically to the pitch of the threading of the screw being driven. For this purpose a spindle-type spring biassed coupling is provided between the screw driving blade and the drive shaft of the motor. As a result of such a coupling the screw driving blade first begins a rotational movement when the drive motor is switched on, and then it superimposes an automatic axial feed advance which adapts itself to the pitch of the screw being driven. An adjustment member provides for adjusting the spindle coupling to the length of the screws being driven.

Abstract: A model-based alarm coordination system coordinates primary and secondary alarm notifications in order to ascertain whether they are caused by a single fault, or multiple faults, in a complex electrical system. The alarm coordination function is part of a larger overall Fault Management Support (FMS) system. The FMS system is a framework that, when combined with object-specific fault management parts, offers uniform fault management functions to managed objects (MOs) within the electrical system. Each MO is viewed as a self-contained, functional unit, and is responsible for its own internal fault management. Therefore, there are no global or centralized fault management functions. Object relation models, based on functional dependencies between objects, are used to automatically solve the alarm coordination problem which arises when a large number of faults are reported in response to a single fault which causes out-of-specification performance in many dependent objects.

Abstract: A communications protocol for a cellular network comprised of a plurality of exchanges each of which includes a software package for providing services to a plurality of subscribers. According to this protocol, efficient communication between two exchanges can be implemented through a handshake procedure in which each exchange identifies the capabilities and features of its software package to the other exchange.

Abstract: An apparatus for separating out the contaminants in a pulp slurry in which the housing of the separator is divided by a perforated screen into an inlet and an outlet section. The inlet section of the separator has a rotating blade mixing means to propel the liquid mixture in the pulp slurry away from the screen and toward the housing wall. The outlet section of the separator has a rotating blade cleaning means which is adjacent the downstream side of the screen for removing contaminants from the upstream side of the screen and moving the removed contaminants into the inlet chamber for further mixing and removal therefrom.

Abstract: A digital switch serves a number of terminal units for switching signal traffic therebetween, the traffic being logically divided into data time slots and control time slots with control packets. It comprises a switch memory for receiving the data time slots, a control memory containing information for facilitating through connection of the data time slots in the switch memory, a control memory terminal for receiving the control time slots and control packets located therein, for writing information into the control memory, and for transmitting acknowledgement packets to called and calling ones of the terminal units, and an occupied/unoccupied memory cooperating with the control memory terminal and storing actual status of each of the terminal units.

Abstract: In a radiotelephone base station receiver having components which cause degradation of a received radio signal, an apparatus for producing a correctly compensated radio signal strength information (RSSI) signal from the degraded received radio signal has an analog radio frequency unit and a digital control unit. The analog radio frequency unit receives the degraded received radio signal and generates a degraded RSSI signal, and includes an analog circuit and addressable memory. The addressable memory has compensated RSSI signal values stored at addresses, and the compensated RSSI signal values correspond to possible degraded RSSI signal values. The addresses are generated from the degraded RSSI signal, which may serve directly as the addresses. The digital control unit is coupled to the analog radio frequency unit, and receives the degraded RSSI signal and generates compensated RSSI signal values based on those in the addressable memory.

Abstract: A slotted rail terminal for highway guardrails. The rail of the terminal contains at least one slotted section extending along the rail and having at least one longitudinal slot of a size sufficient to reduce the ability of the rail to resist bending in response to a loading from one end or the side of the rail. A slot guard is provided which is adapted to be attached to the rail on the side facing away from the highway and downstream of each slotted section relative to expected longitudinal loadings on the rail. The slot guard is configured to abut the rail and span its respective slotted section so as to resist enlargement of each slot. The slot guard enables the slotted section to resist and oppose lateral impacting forces such that the slotted section of the guardrail will act to substantially redirect laterally impacting vehicles.

Abstract: A substantially single phase, single crystalline, highly epitaxial film of Bi.sub.2 CaSr.sub.2 Cu.sub.2 O.sub.8 superconductor which has a T.sub.c (zero resistance) of 83K is provided on a lattice-matched substrate with no intergrowth. This film is produced by a Liquid Phase Epitaxy method which includes the steps of forming a dilute supercooled molten solution of a single phase superconducting mixture of oxides of Bi, Ca, Sr, and Cu having an atomic ratio of about 2:1:2:2 in a nonreactive flux such as KCl, introducing the substrate, e.g., NdGaO.sub.3, into the molten solution at 850.degree. C., cooling the solution from 850.degree. C. to 830.degree. C. to grow the film and rapidly cooling the substrate to room temperature to maintain the desired single phase, single crystalline film structure.

Abstract: An apparatus is described for depositing a thin film (9) of compound materials on selected substrates (48) in an evacuable coating chamber. This apparatus includes a rotating primary surrogate magnetron cathode surface (19) which acts to receive, in-situ, material to be sputtered. Vapor crucibles (2) expose the rotating cathode surface (19) to material vapors (8) which condense on the thermally cooled cathode surface (19) to combine with other coatings on the cathode and are thence rotated through the associated plasma sputter zone (26P) to sputter deposit desired film (9). Auxiliary rotating magnetron cathodes (32) can deposit additional material onto rotating primary cathode (19). Molten material crucible assemblies (31) having coating rollers (34) can convey molten material onto rotating auxiliary thermally cooled cathode surfaces (32) which sputter coat primary cathode.

Abstract: Two press units have axes which lie in a pressing plane which is inclined to the vertical direction and they form a press nip with each other. The two press units are supported by bearing brackets which are coupled in pairs to each other by detachable tension bars which transmit the pressing force. The bearing brackets of the one press unit are supported rigidly (i.e. directly on a machine frame, foundation, or the like) and bear at least a part of the weight of the other press unit. A support device on the machine frame, foundation, or the like at least temporarily takes up a component of the weight of the other press unit which is directed transverse to the pressing plane.

Abstract: A method of effecting automatic callback in a mobile telecommunication system. A calling subscriber is permanently connected to a public switched telephone network and a called subscriber is a mobile unit which moves in the public land mobile network. A centrally located home location register keeps an account of where all mobiles registered in the mobile telecommunication network are located, with the aid of local databases, so-called visitor location registers. The called subscriber calls the called subscriber and finds that the subscriber is busy. The calling subscriber then dials a code, wherewith a reference is stored in a queue in the home location register, this queue relating to the called subscriber. When the called subscriber is free to receive a call, the calling subscriber is informed to this effect. The calling subscriber then lifts his telephone receiver and a connection is set-up between the two subscribers. When the called subscriber answers, the call is considered to have been connected.
