Abstract: ABSTRACT            Data processing equipment suitable for recording details of manually connected telephone calls has a plurality of operator stations with keyboards and VDU's connected in groups to operator's control units which respond to keyed instructions to obtain data from peripheral units storing such data and for recording on magnetic tape cartridge the details of the calls.  The magnetic tape cartridge recording units are duplicated and the data recorded in the two units, which would be the same, is compared and their validity checked.  If both signals are valid, whether they differ or not, they are recorded.  If only one set of signals is valid only the valid signals are recorded by both recorders.  A marker signal may be recorded to indicate that the data signals recorded may be incorrect.

Abstract: METHOD AND APPARATUS FOR SUPPORTING TAPE       ALONG THE PATH OF A ROTATING HEAD          ABSTRACT         In rotating-head magnetic recording, the rotor carrying the magnetic transducer is enlarged in width so that the width of the rotor is much greater than the track width of the head.  The rotor is mounted in the middle of an air bearing mandrel around which magnetic tape is wrapped.  The wide rotor also provides an air bearing for the tape.  The air bearing for the rotor and mandrel is accomplished by forcing air through their cylindrical surfaces.  These cylindrical surfaces may be either a porous material or a nonporous material with holes through which the air may flow.          The wide air bearing rotor provides a very stable platform upon which the magnetic tape may rest while it is scanned by the rotating head.

Abstract: APPARATUS AND METHOD FOR CONDUCTING FINANCIAL TRANSACTIONS Abstract of the Disclosure A currency dispensing apparatus employs a removable portable cartridge having a plurality of compartments for storing currency of differing denominations to be dispensed during successive transactions, another compartment for receiving a journal record printed as each transaction is completed, and a different compartment (preferably defined by a detachable portion of the cartridge) for storing rejected currency.  Upon removal from the apparatus, the cartridge will thus contain all undispensed currency, including rejected currency, and also contain a complete journal record of all transactions conducted at the apparatus using that particular cartridge.  The cartridge comprises two concentric members, the outer having an opening through which currency is dispensed, and the inner providing the compartments.          The appropriate currency compartment is rotatably aligned with the dispensing opening, which is adjacent a dispensing station.  The outer member is also rotatable independently of the inner member to change the position of the opening to enable detachment and later reinsertion of the different compartment.  In a multiple dispensing station transaction terminal having three access stations 120° apart, the outer member is rotatable to the respective stations so that all may be serviced by a single cartridge.

Abstract: ABSTRACT OF THE DISCLOSURE           There is disclosed an apparatus for supporting roll chocks of a work roll in a roll stand housing. This apparatus includes a thrust transmitting head member between the roll chock and a rolling force effecting mechanism such as a screw of a screw down mechanism. The head member has a spherical surface at one end in contact with a mating spherical surface formed at one end of the screw. These spherical surfaces have different radii to make point contact therebetween and to enable rolling contact movement between the head member and the screw in the rocking motion of the roll chock caused by a force in a work-piece generated during a rolling operation, to thereby provide more accurate measurement of tension in the workpiece being rolled by employing force sensing devices acting on the roll chocks. The head member also has inclined surfaces at the other end thereof in registration with mating inclined surfaces formed at one side of the roll chock.  The registration of these mating inclined surfaces make it possible to center the roll chock in the roll stand housing.

Such apparatus includes a connector releasably connecting terminal end portions of said cable for forming said loop, and elements co-operating with such connector and cable for effecting the releasable connection between said portions of each cable, and the seating and tensioning of each newly installed cable to take a share of the load equal to that of each of the other cables while said load is carried by the other cables.  The steps of the method include preforming a uniform section of each terminal end portion of the new, or replacement cable between first holding forces applied at the ends of each section with corresponding bends, and then, while so held, said cable is slack-positioned over a sheave and below the kiln or drum to form an endless loop disposed in one plane, and said sections are then held by a second holding force.  Thereafter, said first holding forces are removed and the loop of said cable between said sections are tensioned by applying a pulling force on one of said sections outwardly of said loop while restricting movement of the other section until the tension of said loop is substantially equal to the tension of the corresponding loops of the other cables, and then holding the tension of said one cable against slackening while removing the pulling force from said one of said sections.

Abstract: Abstract of the Disclosure A decoder for decoding control signals received by a central record/reproduce mechanism of a central dictation system, which control signals are of different levels to control different operating functions of the mechanism.  The control signal is received by a plurality of threshold level detectors each of which is supplied with a different predetermined threshold level.  Depending upon which threshold levels are exceeded by the control signal, respective energizing signals are produced by the associated threshold detectors and these energizing signals are supplied to correspond-ing sensors which produce output signals indicating the level of the control signal,  Diode circuits supply the respective energizing signals from the threshold level detectors to the respective sensors.  An inhibit circuit is connected between the output of a respective threshold level detector and the diode circuit which is connected to the threshold level detector associ-ated with the next lower threshold level.  The inhibit circuit biases the diode circuit in a manner to inhibit the sensor which is connected to the next lower threshold level detector so that when two adjacent threshold levels are exceeded by a control signal, only the sensor associated with the higher of these threshold levels produces an output signal; operation of the next lower sensor is inhibited.

Abstract: 47,512 A FLOW RATE MEASURING DEVICE              ABSTRACT OF THE DISCLOSURE A flow rate metering device having an inlet plenum chamber which accepts fluid flow of any velocity distribu-tion and disperses that fluid to a homogeneous, essentially zero velocity fluid body from which a flow nozzle draws such zero velocity fluid and accelerates it therethrough to obtain a pressure drop.  By measuring the pressure at selec-ted locations upstream and downstream from the nozzle inlet, fluid flow rate through the nozzle can be metered by ref-erence to conventional pressure differential correlations. The upstream pressure tap is preferably in the plenum chamber near the point where fluid velocity is near zero and the downstream pressure tap is preferably disposed in either of two locations:  the downstream race of the flow nozzle or through the wall of a conduit into which the differential pressure nozzle discharges.  Disposed within the plenum chamber is a flow deceleration device which augments the plenum chamber's inherent capability of reducing entering fluid flow velocity to substantially zero.  The flow decel-eration device is preferably located in a low velocity region of the plenum chamber so as to minimize pressure drop therethrough.  The cross-sectional flow area of the plenum chamber is preferably at least nine times that of its inlet port and the length of the plenum chamber in the direction of normal fluid flow is preferably at least three times the inlet port's equivalent diameter.
