Abstract: SECURITY CONTROLLED INFORMATION EXCHANGE SYSTEM Abstract of the Disclosure security con-trolled information exchange system for controlling the orderly exchange of information between two or more users under primary control of security identifiers. Each user is set up with a local user identifier (LUID) and a number of remote user identifiers (RUID).  Also, associated with selected ones of the RUIDs, are jobs which are to be communicated.  A user initiates communication transfer by forwarding to another terminal its LUID and the receiving user compares the received LUID with its list of RUIDs and if a compare is made, the receiver forwards its own LUID to the initiating party.  If a compare is not made, it dis-connects.  The initiating party then compares the LUID which has been forwarded to it with its list of RUIDs and if no compare is made, it disconnects.  If a compare is made, however, it holds onto the line and the called party then sends the jobs which are associated with the RUID which corresponds to the LUID which it received.  Each RUID may be associated with a single unique job which may be forwarded to a calling user or may be associated with a number of jobs which may be chained and automatically forwarded to the calling user.  In addition, a number of RUIDs may be assoc-iated with the same job or with selected ones of jobs in the complete job list.

Abstract: ABSTRACT OF THE DISCLOSURE     A hydrodynamic bearing capable of transmitting thrust and radial loads and able to accommodate angular misalignment between an inner load applying or supporting member rotatably connected to the bearing utilizes an outer cylindrical array of bearing pads disposed about a longitudinal axis, the pads having movable face portions with spherically curved bearing surfaces having a common center of curvature located on the longitudinal axis, the curved surfaces mating with a spherically curved periphery on the load supporting member. The face portions of the bearing pads are supported by a curved, laminated elastomer-inelastic material so that they are swingable about "swing points" located between the axis of rotation of the bearing and the face, portions thereof under the combined influences of friction and load forces exerted thereagainst by the load applying or support-ing member, so that wedge-shaped hydrodynamic gaps are created between the relatively moving bearing surfaces that are filled by the lubricant to maintain the surfaces apart while the motion is occurring through hydrodynamic action. Radial and thrust loads,, as well as angular misalignment between the load supporting member and the bearing pads, are all accommodated by reason of the particular ball and socket relationship between the bearing members, without adversely affecting the hydrodynamic action of the bearing.

Abstract: 47,300 SYSTEM FOR MULTI-MODE CONTROL OF A BOILER FEDPUMP TURBINE              ABSTRACT OF THE DISCLOSURE         A boiler feedpump turbine (BFPT) control system for controlling the rotating speed of a boiler feedpump turbine in a selected one of at least three control modes is disclosed.  The boiler feedpump turbine is mechanically coupled to a boiler feedpump for governing the flow of feedwater pumped by the feedpump to a boiler.  A boiler control turbine speed signal which represents the feedwater requirement of the boiler is provided to the BPFT control system from a conventional boiler feedwater control system.          The flow of feedwater pumped by the feedpump is a function of the rotating speed of the boiler feedpump turbine which is controlled in a selected one of three modes in accordance with the adjustment of a speed set point.  The three control modes include adjusting the speed set point in relation to a turbine speed demand signal generated within the BFPT con-trol system only at values below the boiler control turbine speed signal, adjusting the speed set point in relation to the boiler control turbine speed signal, and overriding the adjustment of the speed set point by the boiler control turbine speed signal to permit adjustment of the speed set point by the turbine speed demand signal beyond the value of the boiler control turbine speed signal.  Transfers between the control modes are performed automatically in response to a set of predetermined conditions and commands.  The BFPT additionally provides for conducting an overspeed test which permits adjustment of the speed set point by the turbine speed demand signal in a predetermined range beyond a rated 47,300 turbine speed value.  This overspeed test function prohibits the speed set point from remaining above the rated turbine speed values at times when not conducting the overspeed test.  The BFPT control system employs a closed-loop primary speed controller which calculates its turbine speed feedback signal from a selected one of two speed transducers.  The other of the two speed transducers may be used if a malfunc-tion is detected in the selected speed transducer.  The BFPT control system further incorporates a degraded manual backup controller which assumes control responsibilities when a malfunction is detected which renders the primary controller inoperative.
