Abstract: ABSTRACT A stored program telecommunications system of the hybrid PBX/ey system type. The system uses two level distributed processor architecture for control and switching and pulse code mudulation (PCM) for speech transmission. The system controller directs operation of the second level or group controllers, there being one group controller for each group of ports. Ports may be station instruments of either the single line or multiple line type, trunk lines or data terminals. Data from the data terminals is generally slower than the repetition rate of PCM data, therefore system time slots capable of PCM transmission may be allotted to handle more than one data terminal through sub-multiplexing of time slots. The sub-multiplexing of PCM time slots is controlled by the system controller acting through the controller for the group initiating the call with a data interface circuit providing access between a data terminal and a group level speech bus. One data interface circuit may control up to four data terminals.

Abstract: INK JET PRINTER             Abstract of the Disclosure An ink jet printer for depositing drops of ink at a plurality of print positions on a moving print receiving medium includes a print head producing at least one jet drop stream directed toward the medium and a charge electrode positioned adjacent the point of drop formation of the jet drop stream.  A charging means repetitively applies a high guard drop potential to the charge electrode during formation of at least every second drop for charging of the drops to a guard charge level.          During formation of the remainder of the drops, either one of a number of relatively low print potentials or a substantially larger catch potential is applied to the charge electrode.  Drops formed during application of a print potential to the electrode may carry a charge of either electrical polarity due the drop-to-drop cross talk from previously formed guard drops.  Drops carrying a guard charge level and drops carrying a catch charge level are deflected by an electric field to a catcher, and drops carrying any of the print charge levels are deflected by the field to associated print positions on the medium.

The direction of motion of each web is changed by the corresponding roller before entry into a roller nip and the web is continuously supported by roller surfaces until departure from the third roller nip. All rollers taking part in transporting the web are individually driven and are individually controll-able in order to regulate the tensions of the entering webs.

Abstract: ABSTRACT OF THE DISCLOSURE         The invention relates to a guide bushing used to maintain alignment of a rotary shaft and in particular to a guide bushing for use as a mining deck bushing.  When drilling blast holes in surface mining operations, it is conventional to pass the drill pipe through a deck bushing located on the floor or deck of the blast hole drill.  During drilling operations the drill pipe has a tendency to run off laterally, and vibrate vertically.  The purpose of the deck bushing is to keep the drill pipe as straight as possible, and prevent wear of the more costly deck.  The pres-ent invention provides a guide bushing for use as a deck bushing and is equipped with a rotatably inner sleeve which is supported by angular journal bearing surfaces and ball bearings located in elongate annular grooves, which allow the guide bushing to main-tain alignment of the drill pipe without premature failure of the ball bearings, grooves or other bearing surfaces.

Abstract: Abstract of the disclosure "Method for fabricating composite transducers".          A  simplified method for fabricating composite transducers by bonding together plates of active (12, 14, 16, 18) and passive (11, 13, 15, 17, 19) materials to form a laminated block (10). The active material is preferably a piezoelectric ceramic. Thereafter, a series of cuts are made in the laminated block to obtain a laminated plate (20) wherein strips (22, 24, 26, 28) of active material are separated from one another by strips (21, 22, 25, 27, 29) of passive material. Laminated plates (20a, 20b, 20c, 20d) and plates (31, 32, 33, 34, 35) of passive material are bonded together to form a block (30) of composite material from which transducers can be cut. Each transducer com-prises a matrix of isolated active regions surrounded by passive material. The method provides composite transducers having fine structures which can be produced without the difficulty of assembling many small rods or sawing deep, narrow grooves.

Abstract: ARRANGEMENT FOR REMOTE ADJUSTMENT OF THE DIMENSIONS OF           A STRAND DURING CONTINUOUS CASTING                 ABSTRACT OF THE DISCLOSURE        A vertical continuous casting mold has a pair of wide walls, and a pair of narrow walls which are received between the wide walls.  The narrow walls are translatable back-and-forth, and also pivotable, in order to change the width of a strand cast in the mold.  Each of the narrow walls is driven by an arrangement which permits the respective narrow wall to be remotely adjusted during casting.  The arrangement for each narrow wall includes a pair of internally threaded sleeves which are respectively articulated to an upper and a lower portion of the corresponding wall.  A rotatable spindle is threaded into each sleeve.  The spindles are operative to cause axial displacement of the associated sleeves in response to rotation of the spindles.  The two spindles for each narrow wall are rotated by a common motor.  A first transmission transmits motion from the motor to one of the spindles, and a second transmission transmits motion from the motor to the other spindle.  The two transmissions are coupled to one another by a coupling device which also connects the transmissions with the motor.  The design is such that, in spite of the mechanical connection between the transmissions, one of the spindles is adjustable independently of the other spindle.  The mechanical connection between the two transmissions associated with a narrow wall reduces the likelihood of uncontrolled rotation of one spindle by itself. The independent adjustability of one of the spindles for each narrow wall makes it possible to achieve all motions of the respective wall which are necessary to change the width of a strand.

During playback, when the remote control signal is detected, the tape is rewound to the beginning of the outgoing message, and the apparatus is set in the record mode to record a new outgoing message.  After the new outgoing message is recorded to the predetermined position, the tape is rewound to the beginning of the outgoing message, and the apparatus is set in the play mode.  During playback, when the remote control signal is detected, the corresponding tape position is detected, thereby preventing the remote control signal from being recorded at the end of the new outgoing message.

The orifice has a central passage for the fuel jet which is discharged from the nozzle and a number of openings surrounding  the  passage.   In order to reduce the noise concomitant with the operation of the burner, the spacing between the peripheries of the neighbouring openings equals at least 50% of the diameter of the openings, and/or the openings in the orifice plate are associated with at least one air duct in the direction of flow.
