Abstract: A B S T R A C T      DIGITAL SWITCHING NETWORK FOR TELECOMMUNICATIONS EXCHANGE      A number of methods are used in the prior art to provide speech sample security in a duplicated switch plane telecommunications switching system and these fall into three categories; (i) use the switching planes in a main/standby mode with errors detected by a check code accompanying the speech sample on the plane in use detected errors cause the standby to be switched-to, (ii) transmit speech across both planes simultaneously and compare and (iii) as per (ii) accompanied by a check code to identify the plane at fault.  Categories (i) and (iii) require "extra" routes to transmit the check code whereas category (ii) can not detect which sample is in error. In the serial transmission switch planes there are no "spare" routes available without creating extra routes for the check code alone.  The basic principle of the invention is to pass the speech through one plane only which is known as the "biased to" plane.  A checkcode is passed through the other "biased from" plane.  Identical routes are used by the speech data and the check code through these respective planes.  The check code is generated in the RX DLT and both the checkcode and the speech data are checked in the Tx DLT.  The DLT selects the biased-to plane under the control of the switch  control system.  The checkcode format used comprises a 4 bit  speech checkcode and a  4 bit checkcode check allowing faults in the "biased from" plane to be detected.

Title: Transitioning between multiple modes of inverter control in a load commutated inverter motor drive

Abstract: TRANSITIONING BETWEEN MULTIPLE MODES OF INVERTER CONTROL IN A LOAD COMMUTATED INVERTER MOTOR DRIVE          Abstract of the Disclosure The load side converter or inverter in a load commutated inverter motor drive, including a source side AC to DC converter coupled to a DC to AC converter via a DC link circuit, is adapted to have at least three and preferably four modes of operation for bringing an AC motor load, and more particularly a synchronous motor, up to speed.  In the preferred embodiment, the first mode constitutes an idle mode wherein the converter thyristors are maintained in a non-conducting state until commanded for normal operation.  The second mode constitutes an initial start-up mode which assumes no knowledge of initial rotor position of the motor and simply utilizes a fixed low frequency firing signal to sequentially gate the thyristors using forced commutation to commutate the off-going thyristor.  Thirdly, a second type of forced commutation mode is next entered into where the inverter frequency is synchronized to the rotor of the motor by sensing pseudo-flux waveforms until 5% to 10% of rated motor speed is achieved whereupon a fourth mode is entered into which comprises a self-commutation mode utilizing a phase lock loop operation using pseudo-flux wave zero crossings as synchronizing signals.         In the three mode embodiment, the third mode is eliminated and the second mode modified to vary the load side converter frequency on a time basis until reaching some preset value (e.g., five (5) to fifteen (15) percent of motor rated frequency) at which time transition is made to the self-commutation mode.

Abstract: ABSTRACT OF THE DISCLOSURE          A two-stage actuator comprises a pair of axially aligned bellows   molded from a thermoplastic material and connected at their adjacent ends by a molded link section integal with the bellows  .  The other end of one of the bellows   is designed to be con-nected to a stationary machine part while the other end of the other bellows is designed to be connected to a movable machine part.  Each bellows has an accordion-type convolution section pneumatically connected through a conduit and a valve to a vacuum source so that the convolution section is axially collapsed by vacuum when applied.  A link member axially extends over the con-volution section of the other bellows and has an end fixed relative to the one bellows.  The other end of the other bellows is in the form of an axially elongated protrusion slidably extending through an opening formed in the other end of the link member.  The protrusion and the opening cooperate to form a one-way connection which allows the protrusion to be moved relative to the opening toward the one bellows but prevents the protru-sion from being moved relative to the opening toward the movable machine part whereby, when the one bellows is axially collapsed, the link member and the other bellows are moved a distance toward the stationary machine part to pull the movable machine part the same distance and, when the other bellows is axially collapsed with the one bellows kept collapsed, the movable machine part is fur-ther pulled an additional distance toward the stationary machine part.

Abstract: Abstract of the Disclosure Method and apparatus for imparting visual surface effects to a relatively moving, thermally modifiable substrate by application of discrete streams of heated pressurized gas to surface areas of the substrate.  The apparatus includes an elongate manifold assembly comprising two gas receiving compartments, each extending across the path of said substrate.  Heated gas from the first compartment passes into the second compartment, which is comprised of a series of chambers with an elongate exit slot positioned closely adjacent the substrate surface.  The gas is uniformly mixed within this second compartment, and may then be directed from the exit slot onto the substrate as a thin, continuous stream or curtain extending the length of the manifold.  By use of blocking streams of relatively cool gas which deflect and dilute selected lateral segments of the heated gas stream in accordance with pattern information after the curtain of heated gas emerges from the exit slot, smaller streams or groups of streams may be formed which squarely impinge on the substrate surface and impart, via thermal modification of the surface, a selected pattern to the substrate.

Abstract: ABSTRACT OF THE DISCLOSURE            An image processing system is characterized in that a plurality of image processing devices having different resolutions are included. An original image to be sent from a selected image processing device is constituted by a base image corresponding to the lowest resolution, and one or more error compensation data corresponding to resolutions changing stepwise from the resolution of the base image to that of the original image. The base image is generated by reducing stepwise the resolution of the original image. The error compensation data is generated by predicting from either a lower resolution image whose resolution is lower than that of the original image, or, the base image, a higher resolution image whose resolution is one step higher, and by encoding error between the predicted image and an actual higher reso-lution image.  When the original image is to be sent to another selected image processing device, image data only up to the one having a resolution of another device are sent.
